+# Architecture
+
+This document covers the internal architecture of the Logfile Navigator (lnav),
+a terminal-based tool for viewing and analyzing log files.
+
+## Goals
+
+The following goals drive the design and implementation of lnav:
+
+- Don't make the user do something that can be done automatically.
+
+ Example: Automatically detect log formats for files instead of making them
+ specify the format for each file.
+
+- Be performant on low-spec hardware.
+
+ Example: Prefer single-threaded optimizations over trying to parallelize
+
+- Operations should be "live" and not block the user from continuing to work.
+
+ Example: Searches are run in the background.
+
+- Provide context-sensitive help.
+
+ Example: When the cursor is over a SQL keyword/function, the help text for
+ that is shown above.
+
+- Show a preview of operations so the user knows what is going to happen.
+
+ Example: When entering a `:filter-out` command, the matched parts of the
+ lines are highlighted in red.
+
+## Overview
+
+The whole of lnav consists of a
+[log file parser](https://docs.lnav.org/en/latest/formats.html),
+[text UI](https://docs.lnav.org/en/latest/ui.html),
+[integrations with SQLite](https://docs.lnav.org/en/latest/sqlext.html),
+[command-line interface](https://docs.lnav.org/en/latest/cli.html), and
+[commands for operating on logs](https://docs.lnav.org/en/latest/commands.html).
+Since the majority of lnav's operations center around logs, the core
+data-structure is the combined log message index. The message index is populated
+when new messages are read from log files. The text UI displays a subset of
+messages from the index. The SQLite virtual-tables allow for programmatic access
+to the messages and lnav's internal state.
+
+[![lnav architecture](docs/lnav-architecture.png)](https://whimsical.com/lnav-architecture-UM594Qo4G3nt2XWaSZA1mh)
+
+## File Monitoring
+
+Each file being monitored by lnav has an associated [`logfile`](src/logfile.hh)
+object, be they plaintext files or files with a recognized format. These
+objects are periodically polled by the main event loop to check if the file
+was deleted, truncated, or new lines added. While reading new lines, if no
+log format has matched yet, each line will be passed through the log format
+regular expressions to try and find a match. Each line that is read is added
+to an index
+
+#### Why is `mmap()` not used?
+
+Note that file contents are consumed using `pread(2)`/`read(2)` and not
+`mmap(2)` since `mmap(2)` does not react well to files changing out from
+underneath it. For example, a truncated file would likely result in a
+`SIGBUS`.
+
+## Log Messages
+
+As files are being indexed, if a matching format is found, the file is
+"promoted" from a plaintext file to a log file. When the file is promoted,
+it is added to the [logfile_sub_source](src/logfile_sub_source.hh), which
+collates all log messages together into a single index.
+
+### Timestamp Parsing
+
+Since all log messages need to have a timestamp, timestamp parsing needs to be
+very efficient. The standard `strptime()` function is quite expensive, so lnav
+includes an optimized custom parser and code-generator in the
+[ptimec](src/ptimec.hh) component. The code-generator is used at compile-time
+to generate parsers for several [common formats](src/time_formats.am).
+
+## Log Formats
+
+[log_format](src/log_format.hh) instances are used to parse lines from files
+into `logline` objects. The majority of log formats are
+[external_log_format](src/log_format_ext.hh) objects that are create from
+[JSON format definitions](https://docs.lnav.org/en/latest/formats.html). The
+built-in definitions are located in the [formats](src/formats) directory. Log
+formats that cannot be handled through a simple regular expression are
+implemented in the [log_format_impls.cc](src/log_format_impls.cc) file.
+
+## User Interface
+
+The lnav text-user-interface is built on top of
+[ncurses](https://invisible-island.net/ncurses/announce.html).
+However, the higher-level functionality of panels, widgets, and such is not
+used. Instead, the following custom components are built on top of the ncurses
+primitives:
+
+- [view_curses](src/view_curses.hh) - Provides the basics for text roles, which
+ allows for themes to color and style text. The `mvwattrline()` function does
+ all the heavy lifting of drawing ["attributed" lines](src/base/attr_line.hh),
+ which are strings that have attributes associated with a given range of
+ characters.
+- [listview_curses](src/listview_curses.hh) - Displays a list of items that are
+ provided by a source.
+- [textview_curses](src/textview_curses.hh) - Builds on the list view by adding
+ support for searching, filtering, bookmarks, etc... The main panel that
+ displays the logs/plaintext/help is a textview.
+- [statusview_curses](src/state-extension-functions.cc) - Draws the status bars
+ at the top and bottom of the TUI.
+- [vt52_curses](src/vt52_curses.hh) - Adapts vt52 escape codes to the ncurses
+ API.
+- [readline_curses](src/readline_curses.hh) - Provides access to the readline
+ library. The readline code is executed in a child process since readline
+ does not get along with ncurses. The child process and readline is set to
+ use a vt52 terminal and the vt52_curses view is uses to translate those
+ escape codes to ncurses.
+
+The following diagram shows the underlying components that make up the TUI:

+Foundation, Inc.
+

+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+## lnav v0.11.1
+
+Features:
+* Additional validation checks for log formats have been
+ added and will result in warnings. Pass `-W` on the
+ command-line to view the warnings. The following new
+ check have been added:
+ - Each regex must have a corresponding sample log message
+ that it matches.
+ - Each sample must be matched by only one regex.
+* Added built-in support for anonymizing content. The
+ `:write-*` commands now accept an `--anonymize` option
+ and there is an `anonymize()` SQL function. The
+ anonymization process will try to replace identifying
+ information with random data. For example, IPv4 addresses
+ are replaced with addresses in the 10.0.0.0/8 range.
+ (This feature is mainly intended to help with providing
+ information to lnav support that does not have sensitive
+ values.)
+* Added `parse_url()` and `unparse_url()` SQL functions for
+ parsing URLs into a JSON object and then back again. Note
+ that the implementation relies on libcurl which has some
+ limitations, like not supporting all types of schemes
+ (e.g. `mailto:`).
+* Added the `subsecond-field` and `subsecond-units` log
+ format properties to allow for specifying a separate
+ field for the sub-second portion of a timestamp.
+* Added a keymap for Swedish keyboards.
+
+Breaking changes:
+* The `regexp_capture()` table-valued-function now returns NULL
+ instead of an empty string for the `capture_name` column if
+ the capture is not named.
+
+Fixes:
+* Reduce the "no patterns have a capture" error to a warning
+ so that it doesn't block lnav from starting up.
+* Some ANSI escape sequences will now be removed before testing
+ regexes against a log message.
+* If a line in a JSON-lines log file does not start with a
+ `{`, it will now be shown as-is and will not have the JSON
+ parse error.
+
+Cost of Doing Business:
+* Migrated from pcre to pcre2.
+
+## lnav v0.11.0
+
+Features:
+* Redesigned the top status area to allow for user-specified
+ messages and added a second line that displays an interactive
+ breadcrumb bar. The top status line now shows the clock and
+ the remaining area displays whatever messages are inserted
+ into the lnav_user_notifications table. The information that
+ was originally on top is now in a second line and organized
+ as breadcrumbs. Pressing `ENTER` will activate the breadcrumb bar
+ and the left/right cursor keys can be used to select a particular
+ crumb while the up/down keys can select a value to switch to.
+ While a crumb is selected, you can also type in some text to do
+ a fuzzy search on the possibilities or, if the crumb represents
+ an array of values, enter the index to jump to.
+* The pretty-print view will now show breadcrumbs that indicate the
+ location of the top line in the view with the prettified structure.
+* Markdown files (those with a .md extension) are now rendered in the
+ TEXT view. The breadcrumb bar at the top will also be updated
+ depending on the section of the document that you are in and you
+ can use it to jump to different parts of the doc.
+* The `:goto` command will now accept anchor links (i.e. `#section-id`)
+ as an argument when the text file being viewed has sections. You
+ can also specify an anchor when opening a file by appending
+ `#<link-name>`. For example, `README.md#screenshot`.
+* Log message comments are now treated as markdown and rendered
+ accordingly in the overlay. Multi-line comments are now supported
+ as well.
+* Metadata embedded in files can now be accessed by the
+ `lnav_file_metadata` table. Currently, only the front-matter in
+ Markdown files is supported.
+* Added an integration with regex101.com to make it easier to edit
+ log message regular expressions. Using the new "management CLI"
+ (activated by the `-m` option), a log format can be created from
+ a regular expression entry on regex101.com and existing patterns
+ can be edited.
+* In the spectrogram view, the selected value range is now shown by
+ an overlay that includes a summary of the range and the number of
+ values that fall in that range. There is also a detail panel at
+ the bottom that shows the log-messages/DB-rows whose values are in
+ that range. You can then press TAB to focus on the detail view
+ and scroll around.
+* Add initial support for pcap(3) files using tshark(1).
+* SQL statement execution can now be canceled by pressing `CTRL+]`
+ (same as canceling out of a prompt).
+* To make it possible to automate some operations, there is now an
+ `lnav_events` table that is updated when internal events occur
+ within lnav (e.g. opening a file, format is detected). You
+ can then add SQLite `TRIGGER`s to this table that can perform a
+ task by updating other tables.
+* Tags can automatically be added to messages by defining a pattern
+ in a log format. Under a format definition, add the tag name
+ into the "tags" object in a format definition. The "pattern"
+ property specifies the regular expression to match against a line
+ in a file that matches the format. If a match is found, the tag
+ will be applied to the log message. To restrict matches to
+ certain files, you can add a "paths" array whose object elements
+ contain a "glob" property that will be matched against file names.
+* Log messages can now be detected automatically via "watch
+ expressions". These are SQL expressions that are executed for
+ each log message. If the expressions evaluates to true, an
+ event is published to the `lnav_events` table that includes the
+ message contents.
+* Added the `regexp_capture_into_json()` table-valued-function that
+ is similar to `regexp_capture()`, but returns a single row with a
+ JSON value for each match instead of a row for each capture.
+* Added a `top_meta` column to the lnav_views table that contains
+ metadata related to the top line in the view.
+* Added a `log_opid` hidden column to all log tables that contains
+ the "operation ID" as specified in the log format.
+* Moved the `log_format` column from the all_logs table to a hidden
+ column on all tables.
+* Add format for UniFi gateway.
+* Added a `glob` property to search tables defined in log formats
+ to constrain searches to log messages from files that have a
+ matching log_path value.
+* Initial indexing of large files should be faster. Decompression
+ and searching for line-endings are now pipelined, so they happen
+ in a thread that is separate from the regular expression matcher.
+* Writing to the clipboard now falls back to OSC 52 escape sequence
+ if none of the clipboard commands could be detected. Your
+ terminal software will need to support the sequence and you may
+ need to explicitly enable it in the terminal.
+* Added the `:export-session-to <path>` command that writes the
+ current session state to a file as a list of commands/SQL
+ statements. This script file can be executed to restore the
+ majority of the current state.
+* Added the `echoln()` SQL function that behaves similarly to the
+ `:echo` command, writing its first argument to the current
+ output.
+* Added `encode()` and `decode()` SQL functions for transcoding
+ blobs or text values using one of the following algorithms:
+ base64, hex, or uri.
+* In regular expressions, capture group names are now semantically
+ highlighted (e.g. in the capture, `(?<name>\w+)`, "name" would
+ have a unique color). Also, operations or previews that use
+ that regular expression will highlight the matched data with
+ the same color.
+* Added an lnav_views_echo table that is a real SQLite table that
+ you can create TRIGGERs on in order to perform actions when
+ scrolling in a view.
+* Added a `yaml_to_json()` SQL function that converts a YAML
+ document to the equivalent JSON.
+
+Breaking Changes:
+* Formats definitions are now checked to ensure that values have a
+ corresponding capture in at least one pattern.
+* Added a 'language' column to the lnav_view_filters table that
+ specifies the language of the 'pattern' column, either 'regex'
+ or 'sql'.
+* Timestamps that do not have a day or month are rewritten to a
+ full timestamp like YYYY-MM-DD HH:MM:SS.
+* Removed the summary overlay at the bottom of the log view that
+ displayed things like "Error rate" and the time span. It doesn't
+ seem like anyone used it.
+* Removed the `log_msg_instance` column from the logline and search
+ tables since it causes problems with performance.
+* Search tables now search for multiple matches within a message
+ instead of stopping at the first hit. Each additional match is
+ returned as a separate row. A `match_index` column has been
+ added to capture the index of the match within the message.
+ The table regex is also compiled with the "multiline" flag enabled
+ so the meaning of the `^` and `$` metacharacters are changed
+ to match the start/end of a line instead of the start/end of
+ the entire message string.
+* Search tables defined in formats are now constrained to only
+ match log messages that are in that log format instead of all
+ log messages. As a benefit, the search table now includes
+ the columns that are defined as part of the format.
+* The lnav_view_filters table will treats the tuple of
+ (view_name, type, language, pattern) as a `UNIQUE` index and
+ will raise a conflict error on an `INSERT`. Use `REPLACE INTO`
+ instead of `INSERT INTO` to ignore conflict error.
+* The types of SQL values stored as local variables in scripts
+ is now preserved when used as bound variables at a later point
+ in the script.
+
+Fixes:
+* Toggling enabled/disabled filters when there is a SQL expression
+ no longer causes a crash.
+* Fix a crash related to long lines that are word wrapped.
+* Multiple SQL statements in a SQL block of a script are now
+ executed instead of just the first one.
+* In cases where there were many colors on screen, some text would
+ be colored incorrectly.
+* The pretty-print view now handles ANSI escape sequences.
+* The "overstrike" convention for doing bold and underline is now
+ supported. (Overstrike is a character followed by a backspace
+ and then the same character for bold or an underscore for
+ underline.)
+* The `:eval` command now works with searching (using the '/'
+ prefix).
+
+## lnav v0.10.1
+
+Features:
+* Added `:show-only-this-file` command that hides all files except the
+ one for the top line in the view.
+* The `:write-raw-to` command now accepts a `--view` flag that specifies
+ the source view for the data to write. For example, to write the
+ results of a SQL query, you would pass `--view=db` to the command.
+* The commands used to access the clipboard are now configured through
+ the "tuning" section of the configuration.
+* Added an `lnav_version()` SQL function that returns the current
+ version string.
+* Added basic support for the logfmt file format. Currently, only files
+ whose lines are entirely logfmt-encoded are supported. The lines
+ must also contain either a field named `time` or `ts` that contains
+ the timestamp.
+* Added the `logfmt2json()` SQL function to convert a string containing
+ a logfmt-encoded message into a JSON object that can be operated on
+ more easily.
+* Added the `gzip()` and `gunzip()` SQL functions to compress values
+ into a blob and decompress a blob into a string.
+Interface changes:
+* The xclip implementation for accessing the system clipboard now writes
+ to the "clipboard" selection instead of the "primary" selection.
+* The 'query' bookmark type and `y`/`Y` hotkeys have been removed due to
+ performance issues and the functionality is probably rarely used.
+Bug Fixes:
+* The text "send-input" would show up on some terminals instead of
+ ignoring the escape sequence. This control sequence was only
+ intended to be used in the test suite.
+* Remote file synchronization has been optimized a bit.
+* Configuration values loaded from the `~/.lnav/configs` directory
+ are now included in the default configuration, so they won't be
+ saved into the `~/.lnav/config.json` user configuration file.
+* Key handling in the visual filter editor will no longer swallow
+ certain key-presses when editing a filter.
+* Scrolling performance restored in the SQL view.
+* The `:redirect-to` command now works with `/dev/clipboard`
+* The field overlay (opened by pressing 'p') now shows `log_time`
+ for the timestamp field instead of the name defined in the format.
+* The search term in the bottom status bar will now update properly
+ when switching views.
+* The "Out-Of-Time-Order Message" overlay will be shown again.
+* The tab for the "Files" panel will be highlighted in red if there
+ is an issue opening a file.
+* Overwritten files should be reloaded again.
+* The `jget()` SQL function now returns numbers with the correct type.
+* The `json_contains()` SQL function now returns false if the first
+ argument is NULL instead of NULL.
+* The local copies of remote files are now cleaned up after a couple
+ days of the host not being accessed.
+* The initial loading and indexing phase has been optimized.
+
+## lnav v0.10.0
+
+Features:
+* Files on remote machines can be viewed/tailed if they are accessible
+ via SSH. The syntax for specifying the host and path is similar to
+ scp. For example, to view the files in the /var/log directory on the
+ machine `host1.example.org`:
+ ```console
+ $ lnav user@host1.example.org:/var/log
+ ```
+ Note that you must be able to log into the machine without any
+ interaction.
+* Added the `:filter-expr` command to filter log messages based on an SQL
+ expression. This command allows much greater control over filtering.
+* Added the `:mark-expr` command to mark log messages based on an SQL
+ expression. This command makes it easier to programmatically mark
+ log messages compared to using SQL.
+* Added support for archive files, like zip, and other compression formats,
+ like xz, when compiled with libarchive. When one of these types of
+ files is detected, they are unpacked into a temporary directory and
+ all the files are loaded into lnav.
+* Added an `xpath()` table-valued function for extracting values from
+ strings containing XML snippets.
+* Added the `:prompt` command to allow for more customization of prompts.
+ Combined with a custom keymapping, you can now open a prompt and prefill
+ it with a given value. For example, a key could be bound to the
+ following command to open the command prompt with `:filter-in `
+ already filled in:
+ ```lnav
+ :prompt command : 'filter-in '
+ ```
+* Added support for the W3C Extended Log File Format with the name
+ `w3c_log`. Similarly to the bro log format, the header is used to
+ determine the columns in a particular file. However, since the columns
+ can be different between files, the SQL table only has a well-known set
+ of columns and the remainder are accessible through JSON-objects stored
+ in columns like `cs_headers` and `sc_headers`.
+* Added support for the S3 Access File Format.
+* To jump to the first search hit above the top line in a view, you can
+ press `CTRL+J` instead of `ENTER` in the search prompt. Pressing `ENTER`
+ will jump to the first hit below the current window.
+* Filtering, as a whole, can be now disabled/enabled without affecting
+ the state of individual filters. This includes text and time-filters
+ (i.e. `:hide-lines-before`). You can enable/disable filtering by:
+ pressing `f` in the filter editor UI; executing the `:toggle-filtering`
+ command; or by doing an `UPDATE` on the "filtering" column of the
+ `lnav_views` SQLite table.
+* Themes can now include definitions for text highlights under:
+ `/ui/theme-defs/<theme_name>/highlights`
+* Added a "grayscale" theme that isn't so colorful.
+* Added the `humanize_file_size()` SQL function that converts a numeric size
+ to a human-friendly string.
+* Added the `sparkline()` SQL function that returns a "sparkline" bar made
+ out of unicode characters. It can be used with a single value or as
+ an aggregator.
+* Added a `log_time_msecs` hidden column to the log tables that returns
+ the timestamp as the number of milliseconds from the epoch.
+* Added an `lnav_top_file()` SQL function that can be used to get the
+ name of the top line in the top view or NULL if the line did not come
+ from a file.
+* Added a `mimetype` column to the lnav_file table that returns a guess as
+ to the MIME type of the file contents.
+* Added a `content` hidden column to the lnav_file table that can be used
+ to read the contents of the file. The contents can then be passed to
+ functions that operate on XML/JSON data, like `xpath()` or `json_tree()`.
+* Added an `lnav_top_view` SQL VIEW that returns the row for the top view
+ in the lnav_views table.
+* The `generate_series()` SQLite extension is now included by default.
+ One change from the standard implementation is that both the start and
+ stop are required parameters.
+* Added the `;.read` SQL command for executing a plain SQL file.
+* Added the `-N` flag so that lnav will run without opening the default
+ syslog file.
+
+Interface Changes:
+* When copying log lines, the file name and time offset will be included
+ in the copy if they are enabled.
+* Log messages that cannot be parsed properly will be given an "invalid"
+ log level and the invalid portions colored yellow.
+* The range_start and range_stop values of the `regexp_capture()` results
+ now start at 1 instead of zero to match with what the other SQL string
+ functions expect.
+* The `:write-cols-to` command has been renamed to `:write-table-to`.
+* The DB view will limit the maximum column width to 120 characters.
+* The `:echo` command now evaluates its message to do variable
+ substitution.
+* The `:write-raw-to` command has been changed to write the original
+ log file content of marked lines. For example, when viewing a JSON
+ log, the JSON-Line values from the log file will be written to the
+ output file. The `:write-view-to` command has been added to perform
+ the previous work of `:write-raw-to` where the raw content of the view
+ is written to the file.
+
+Fixes:
+* Unicode text can now be entered in prompts.
+* The `replicate()` SQL function would cause a crash if the number of
+ replications was zero.
+* Many internal improvements.
+
+## lnav v0.9.0
+
+Features:
+* Added support for themes and included a few as well: default, eldar,
+ monocai, night-owl, solarized-light, and solarized-dark. The theme
+ can be changed using the `:config` command, like so:
+ ```lnav
+ :config /ui/theme night-owl
+ ```
+ Consult the online documentation for defining a new theme at:
+ https://lnav.readthedocs.io/en/latest/config.html#theme-definitions
+* Added support for custom keymaps and included the following: de, fr,
+ uk, us. The keymap can be changed using the `:config` command, like so:
+ ```lnav
+ :config /ui/keymap uk
+ ```
+ Consult the online documentation for defining a new keymap at:
+ https://lnav.readthedocs.io/en/latest/config.html#keymap-definitions
+* The following JSON-Schemas have been published for the log format and
+ configuration JSON files:
+ - https://lnav.org/schemas/format-v1.schema.json
+ - https://lnav.org/schemas/config-v1.schema.json
+
+ Formats should be updated to reference the schema using the `$schema`
+ property.
+* Indexing of new data in log files can now be paused by pressing `=`
+ and unpaused by pressing it again. The bottom status bar will display
+ 'Paused' in the right corner while paused.
+* CMake is now a supported way to build.
+* When viewing data from the standard-input, a symbolic name can be used
+ to preserve session state. The name can be changed using the
+ `|rename-stdin` lnav script or by doing an `UPDATE` to the filepath
+ column of the lnav_file table. For example, to assign the name
+ "journald", the following SQL statement can be executed in lnav:
+ ```lnav
+ ;UPDATE lnav_file SET filepath='journald' WHERE filepath='stdin'
+ ```
+* The size of the terminal can be accessed in SQL using the `$LINES` and
+ `$COLS` variables.
+* The `raise_error(msg)` SQL function has been added to make it easier to
+ raise an error in an lnav script to stop execution and notify the user.
+* Added the `json_concat()` function to make it easier to append/concatenate
+ values onto arrays.
+* Added the `:write-jsonlines-to` command that writes the result of a SQL
+ query to a file in the JSON Lines format.
+
+Interface Changes:
+* Data piped into lnav is no longer dumped to the console after exit.
+ Instead, a file containing the data is left in `.lnav/stdin-captures/`
+ and a message is printed to the console indicating the file name.
+* In time-offset mode, the deltas for messages before the first mark
+ are now negative instead of relative to the start of the log.
+* The $XDG_CONFIG_HOME environment variable (or `~/.config` directory) are
+ now respected for storing lnav's configuration. If you have an existing
+ `~/.lnav` directory, that will continue to be used until you move it to
+ `$XDG_CONFIG_HOME/lnav` or `~/.config/lnav`.
+* Removed the `:save-config` command. Changes to the configuration are now
+ immediately saved.
+
+Fixes:
+* Added 'notice' log level.
+* If a `timestamp-format` is used in an element of a `line-format`, the
+ field name is ignored and a formatted timestamp is always used.
+* Ignore stdin when it is connected to `/dev/null`.
+
+## lnav v0.8.5
+
+Features:
+* Added a visual filter editor to make it easier to update existing
+ filters. The editor can be opened by pressing `TAB`. Once the editor
+ is opened, you can create/delete, enable/disable, and edit the patterns
+ with hotkeys.
+* Added an `lnav_view_filters` SQL table that can be used to
+ programmatically manipulate filters.
+* Added an `lnav_view_filter_stats` SQL table that contains the number of
+ times a given filter matched a line in the view.
+* Added a `log_filters` column to log tables that can be used to see what
+ filters matched the log message.
+* A history of locations in a view is now kept so that you can jump back
+ to where you were previously using the `{` and `}` keys. The location
+ history can also be accessed through the `:prev-location` and
+ `:next-location` commands.
+* The `:write-*` commands will now accept `/dev/clipboard` as a file name
+ that writes to the system clipboard.
+* The `:write-to` and `:write-raw-to` commands will now print out comments
+ and tags attached to the lines.
+* Added a `:redirect-to <path>` command to redirect command output to the
+ given file. This command is mostly useful in scripts where one might
+ want to redirect all output from commands like `:echo` and `:write-to -`
+ to a single file.
+* If a log file format has multiple patterns for matching log messages,
+ each pattern is now tried to match a message in a file. Previously,
+ only one pattern was ever used for an entire file.
+* Added haproxy log format from Peter Hoffmann.
+* Added `spooky_hash()` and `group_spooky_hash()` SQL functions to
+ generate a hash of their parameters.
+* Added `time_offset` to the `lnav_file` table so that the timestamps in
+ a file can be adjusted programmatically.
+
+Interface Changes:
+* The auto-complete behavior in the prompt has been modified to fall back
+ to a fuzzy search if the prefix search finds no matches. For example,
+ typing in `:fin` and pressing TAB would previously not do anything.
+ Now, the `:fin` will be completed to `:filter-in ` since that is a
+ strong fuzzy match. If there are multiple matches, as would happen
+ with `:dfil`, readline's menu-complete behavior will be engaged and
+ you can press `TAB` cycle through the options.
+* Added `CTRL+F` to toggle the enabled/disabled state of all filters for the
+ current view.
+* The `-r` flag is now for recursively loading files. The functionality
+ for loading rotated files is now under the `-R` flag.
+* The current search term is now shown in the bottom status bar.
+* Some initial help text is now shown for the search and SQL prompts to
+ refresh the memory.
+* When entering the `:comment` command for a line with a comment, the
+ command prompt will be filled in with the existing comment to make
+ editing easier.
+* Hidden fields now show up as a unicode vertical ellipsis (⋮) instead of
+ three-dot ellipsis to save space.
+* Pressing 7/8 will now move to the previous/next minute.
+* The `:write-raw-to` command has been changed to write the entire
+ contents of the current view and a `:write-screen-to` command has been
+ added to write only the current screen contents.
+* Disabled filters are now saved in sessions.
+* The `:adjust-log-time` command now accepts relative times as input.
+
+Fixes:
+* The `:write-json-to` command will now pass through JSON cells as their
+ JSON values instead of a JSON-encoded string.
+
+## lnav v0.8.4
+
+Features:
+* Added the `:comment` command that can be used to attach a comment to a
+ log line. The comment will be displayed below the line, like so:
+ ```
+ 2017-01-01T15:30:00 error: computer is on fire
+ + This is where it all went wrong
+ ```
+ The `:clear-comment` command will remove the attached comment. Comments
+ are searchable with the standard search mechanism and they are available
+ in SQL through the `log_comment` column.
+* Added the `:tag`, `:untag`, and `:delete-tags` commands that can be used
+ to attach/detach tags on the top log line and delete all instances of
+ a tag. Tags are also searchable and are available in SQL as a JSON
+ array in the `log_tags` column.
+* Pressing left-arrow while viewing log messages will reveal the source
+ file name for each line and the unique parts of the source path.
+ Pressing again will reveal the full path.
+* The file name section of the top status line will show only the unique
+ parts of the log file path if there is not enough room to show the full
+ path.
+* Added the `:hide-unmarked-lines` and `:show-unmarked-lines` commands
+ that hide/show lines based on whether they are bookmarked.
+* Added the `json_contains()` SQL function to check if a JSON value
+ contains a number of a string.
+* The relative time parser recognizes "next" at the beginning of the
+ input, for example, "next hour" or "next day". Handy for use in the
+ `:goto` command.
+* Added a "text-transform" option for formatting JSON log messages. The
+ supported options are: none, uppercase, lowercase, and capitalize.
+* Added a special `__level__` field name for formatting JSON messages so
+ that the lnav level name can be used instead of the internal value in
+ the JSON object.
+* Added a log format for journald JSON logs.
+
+Interface Changes:
+* When typing in a search, instead of moving the view to the first match
+ that was found, the first ten matches will be displayed in the preview
+ window.
+* The pretty-print view maintains highlighting from the log view.
+* The pretty-print view no longer tries to reverse lookup IP addresses.
+* The online help for commands and SQL functions now includes a 'See Also'
+ section that lists related commands/functions.
+
+Fixes:
+* The HOME key should now work in the command-prompt and move the cursor
+ to the beginning of the line.
+* The `:delete-filter` command should now tab-complete existing filters.
+* Milliseconds can now be used in relative times (e.g. 10:00:00.123)
+* The `J`/`K` hotkeys were not marking lines correctly when the bottom of
+ the view was reached.
+* The level field in JSON logs should now be recognized by the level
+ patterns in the format.
+
+## lnav v0.8.3
+
+Features:
+* Support for the Bro Network Security Monitor (https://www.bro.org) log
+ file format.
+* Added an `fstat()` table-valued function for querying the local
+ filesystem.
+* Added `readlink()` and `realpath()` SQL functions.
+* Highlights specified in log formats can now specify the colors to use
+ for the highlighted parts of the log message.
+* Added a `:quit` command.
+* Added a `/ui/default-colors` configuration option to specify that the
+ terminal's default background and foreground colors should be used
+ instead of black and white.
+
+Interface Changes:
+* Pressing delete at a command-prompt will exit the prompt if there is no
+ other input.
+
+Fixes:
+* The help view now includes all the command-help that would pop up as
+ you entered commands and SQL queries.
+* Hidden fields and lines hidden before/after times are now saved in the
+ current session and restored.
+* Unicode characters should now be displayed correctly (make sure you
+ have LANG set to a UTF-8 locale).
+
+## lnav v0.8.2
+
+Features:
+* The timestamp format for JSON log files can be specified with the
+ `timestamp-format` option in the `line-format` array.
+* Added "min-width", "max-width", "align", and "overflow" options to the
+ "line-format" in format definitions for JSON log files. These options
+ give you more control over how the displayed line looks.
+* Added a "hidden" option to log format values so that you can hide JSON
+ log fields from being displayed if they are not in the line format.
+* Added a `rewriter` field to log format value definitions that is a
+ command used to rewrite the field in the pretty-printed version of a
+ log message. For example, the HTTP access log format will rewrite the
+ status code field to include the textual version (e.g. 200 (OK)).
+* Log message fields can now be hidden using the `:hide-fields` command or
+ by setting the 'hidden' property in the log format. When hidden, the
+ fields will be replaced with a yellow ellipsis when displayed. Hiding
+ large fields that contain extra details can make the log easier to read.
+ The `x` hotkey can be used to quickly toggle whether these fields are
+ displayed or not.
+* Added a `:mark` command to bookmark the top line in the current view.
+* Added an `:alt-msg` command that can be used to set the text to be
+ displayed in the bottom right of the command line. This command is
+ mostly intended for use by hotkey maps to set the help text.
+* In lnav scripts, the first row of a SQL query result will now be turned
+ into local variables that can be referenced in other commands or
+ queries. For example, the following script will print the number one:
+ ```lnav
+ ;SELECT 1 as foobar
+ :eval :echo ${foobar}
+ ```
+* Added an `lnav_view_stack` SQL table that gives access to the view
+ stack.
+* Added a `top_time` column to the lnav_views table so that you can get
+ the timestamp for the top line in views that are time-based as well as
+ allowing you to move the view to a given time with an UPDATE statement.
+* Added a 'search' column to the lnav_views table so that you can perform
+ a text search programmatically.
+* Added a `regexp_capture(<string>, <pattern>)` table-valued function for
+ getting detailed results from matching a regular expression against a
+ string.
+* Added a `timediff(<time1>, <time2>)` SQL function for computing the
+ difference between two relative or absolute timestamps.
+* Log formats can now define a default set of highlights with the
+ "highlights" property.
+* Added a `|search-for <pattern>` built-in script that can be used to
+ start a search from the command-line.
+* Log format definitions can now specify the expected log level for a
+ sample line. This check should make it easier to validate the
+ definition.
+
+Interface Changes:
+* Command and SQL documentation is now displayed in a section at the
+ bottom of the screen when a command or query is being entered. Some
+ commands will also display a preview of the command results. For
+ example, the `:open` command will display the first ten lines of the
+ file to be opened and the `:filter-out` command will highlight text
+ that matches in the current view. The preview pane can be shown/hidden
+ by pressing `CTRL-P`.
+* The color used for text colored via `:highlight` is now based on the
+ the regex instead of randomly picked so that colors are consistent
+ across invocations.
+* The "graph" view has been removed since it's functionality has been
+ obsoleted by other features, like `:create-search-table`.
+* When doing a search, if a hit is found within a second after hitting
+ `<ENTER>`, the view will move to the matched line. The previous behavior
+ was to stay on the current line, which tended to be a surprise to new
+ users.
+* Pressing `n`/`N` to move through the next/previous search hit will now
+ skip adjacent lines, up to the vertical size of the view. This should
+ make scanning through clusters of hits much faster. Repeatedly
+ pressing these keys within a short time will also accelerate scanning
+ by moving the view at least a full page at a time.
+
+Breaking Changes:
+* The captured timestamp text in log files must fully match a known format
+ or an error will be reported. The previous behavior was to ignore any
+ text at the end of the line.
+
+Fixes:
+* You can now execute commands from the standard input by using a dash (`-`)
+ with the `-f` command-line argument. Reading commands from a file
+ descriptor should also work, for example, with the following bash
+ syntax:
+ ```console
+ $ lnav -f <(echo :open the-file-to-open)
+ ```
+* Programming language syntax highlighting should now only be applied to
+ source code files instead of everywhere.
+
+## lnav v0.8.1
+
+Features:
+* Added a spectrogram command and view that displays the values of a
+ numeric field over time. The view works for log message fields or
+ for database result columns.
+* Log formats can now create SQL views and execute other statements
+ by adding `.sql` files to their format directories. The SQL scripts
+ will be executed on startup.
+* Added `json_group_object` and `json_group_array` aggregate SQL
+ functions that collects values from a GROUP BY query into a JSON
+ object or array, respectively.
+* The SQL view will now graph values found in JSON objects/arrays in
+ addition to the regular columns in the result.
+* Added an `regexp_match(<re>, <str>)` SQL function that can be used to
+ extract values from a string using a regular expression.
+* Added an `extract(<str>)` SQL function that extracts values using the
+ same data discover/extraction parser used in the `logline` table.
+* Added a "summary" overlay line to the bottom of the log view that
+ displays how long ago the last message was received, along with the
+ total number of files and the error rate over the past five minutes.
+* Pressing `V` in the DB view will now check for a column with a
+ timestamp and move to the corresponding time in the log view.
+* Added `a`/`A` hotkeys to restore a view previously popped with `q`/`Q`.
+* Added `:hide-lines-before`, `:hide-lines-after`, and
+ `:show-lines-before-and-after` commands so that you can filter out
+ log lines based on time.
+* Scripts containing lnav commands/queries can now be executed using
+ the pipe (`|`) hotkey. See the documentation for more information.
+* Added an `:eval` command that can be used to execute a command or
+ query after performing environment variable substitution.
+* Added an `:echo` command that can be useful for scripts to message
+ the user.
+* The `log_part` column can now be set with an SQL `UPDATE` statement.
+* Added a `log_body` hidden column that returns the body of the log
+ message.
+* Added `:config`, `:reset-config`, and `:save-config` commands to change
+ configuration options, reset to default, and save them for future
+ executions.
+* Added a `/ui/clock-format` configuration option that controls the time
+ format in the top-left corner.
+* Added a `/ui/dim-text` configuration option that controls the brightness
+ of text in the UI.
+* Added support for TAI64 timestamps (http://cr.yp.to/libtai/tai64.html).
+* Added a safe execution mode. If the `LNAVSECURE` environment variable is
+ set before executing lnav, the following commands are disabled:
+ - `:open`
+ - `:pipe-to`
+ - `:pipe-line-to`
+ - `:write-*-to`
+
+ This makes it easier to run lnav with escalated privileges in restricted
+ environments, without the risk of users being able to use the above
+ mentioned commands to gain privileged access.
+
+Interface Changes:
+* The `o`/`O` hotkeys have been reassigned to navigate through log
+ messages that have a matching "opid" field. The old action of
+ moving forward and backward by 60 minutes can be simulated by
+ using the `:goto` command with a relative time and the `r`/`R`
+ hotkeys.
+* Log messages with timestamps that pre-date previous log messages will
+ have the timestamp highlighted in yellow and underlined. These out-
+ of-time-order messages will be assigned the time of the previous
+ message for sorting purposes. You can press the 'p' hotkey to examine
+ the 'Received Time' of the message as well as the time parsed from the
+ original message. A `log_actual_time` hidden field has also been
+ added to the SQLite virtual table so you can operate on the original
+ message time from the file.
+* The `A`/`B` hotkeys for moving forward/backward by 10% line increments
+ have been reassigned to `[` and `]`. The `a` and `A` hotkeys are now
+ used to return to the previously popped view while trying to preserve
+ the time range. For example, after leaving the spectrogram view with
+ 'q', you can press 'A' return to the view with the top time in the
+ spectrogram matching the top time in the log view.
+* The 'Q' hotkey now pops the current view off of the stack while
+ maintaining the top time between views.
+
+Fixes:
+* Issues with tailing JSON logs have been fixed.
+* The `jget()` SQL function should now work for objects nested in arrays.
+
+## lnav v0.8.0
+
+Features:
+* Integration with "papertrailapp.com" for querying and tailing
+ server log and syslog messages. See the Papertrail section in
+ the online help for more details.
+* Remote files can be opened when lnav is built with libcurl v7.23.0+
+* SQL queries can now be done on lines that match a regular expression
+ using the `log_search` table or by creating custom tables with the
+ `:create-search-table` command.
+* Log formats that are "containers" for other log formats, like
+ syslog, are now supported. See the online help for more
+ information.
+* Formats can be installed from git repositories using the `-i` option.
+ A standard set of extra formats can be installed by doing
+ `lnav -i extra`. (You must have git installed for this to work.)
+* Added support for 'VMware vSphere Auto Deploy' log format.
+* Added a 'sudo' log format.
+* Added hotkeys to move left/right by a smaller increment (H/L or
+ Shift+Left/Shift+Right).
+* A color-coded bar has been added to the left side to show where
+ messages from one file stop and messages from another file start.
+* The `-C` option will now try to check any specified log files to
+ make sure the format(s) match all of the lines.
+* Added an `all_logs` SQLite table that contains the message format
+ extracted from each log line. Also added a `;.msgformat` SQL command
+ that executes a query that returns the counts for each format and the
+ first line where the format was seen.
+* Added an `lnav_views` SQLite table that can be used to query and
+ change the lnav view state.
+* When typing in a command, the status bar will display a short
+ summary of the currently entered command.
+* Added a `:delete-filter` command.
+* Added a `log_msg_instance` column to the logline and log_search
+ tables to make it easier to join tables that are matching log
+ messages that are ordered.
+* Added a `timeslice()` function to SQLite so that it is easier to
+ group log messages by time buckets.
+* The `:goto` command now supports relative time values like
+ `a minute ago`, `an hour later`, and many more.
+
+Interface Changes:
+* The `r`/`R` hotkeys have been reassigned to navigate through the log
+ messages by the relative time value that was last used with the
+ `:goto` command.
+
+Fixes:
+* The pretty-print view should now work for text files.
+* Nested fields in JSON logs are now supported for levels, bodies, etc...
+* Tab-completion should work for quoted SQL identifiers.
+* 'lo-fi' mode key shortcut changed to `CTRL+L`.
+* 'redraw' shortcut removed. Relegated to just a command.
+* Fixed lnav hang in pretty-print mode while doing a dns lookup.
+* The generic log message parser used to extract data has been
+ optimized and should be a bit faster.
+
+## lnav v0.7.3
+
+Features:
+* Add `:pipe-to` and `:pipe-line-to` commands that pipe the currently
+ marked lines or the current log message to a shell command,
+ respectively.
+* Added a "pretty-print" view (P hotkey) that tries to reformat log
+ messages so that they are easier to read.
+* Added a `:redraw` command (CTRL+L hotkey) to redraw the window in
+ case it has been corrupted.
+* Added a `:relative-goto` command to move the current view relative
+ to its current position.
+* Experimental support for linking with jemalloc.
+* The plain text view now supports filtering.
+* Added `:next-mark` and `:prev-mark` commands to jump to the next or
+ previous bookmarked line (e.g. error, warning, ...)
+* Added a `:zoom-to` command to change the zoom level of the histogram
+ view.
+* Log formats can now define their own timestamp formats with the
+ `timestamp-format` field.
+
+Fixes:
+* Autotools scripts overhaul.
+* Added a configure option to disable linking with libtinfo. The newer
+ versions of ncurses don't require it, however the build silently pulls
+ it in as a dependency, if it is available on the system. This can be
+ explicitly disabled using the `--disable-tinfo` option during configure.
+* Fixed the configure script behavior to ignore the values specified using
+ the CFLAGS and LDFLAGS environment variables while searching for sqlite3
+ when `--with-sqlite3` switch was specified without the prefix.
+* The configure script now recognizes libeditline symlink'ed to masquerade
+ as libreadline. This previously used to cause problems at compile time,
+ specially on OS X. If you come across this error, use the
+ `--with-readline=prefix` switch to specify the path to the correct
+ location of libreadline.
+* The order that log formats are tried against a log file is now
+ automatically determined so that more specific formats are tested
+ before more general ones. The order is determined on startup based on
+ how each format matches each other formats sample lines.
+* Command files (i.e. those executed via the `-f` flag) now support
+ commands/queries that span more than one line.
+* Added more log levels: stats, debug2 - debug5.
+
+## lnav v0.7.2
+
+* Added log formats for vdsm, openstack, and the vmkernel.
+* Added a "lo-fi" mode (L hotkey) that dumps the displayed log lines
+ to the terminal without any decorations. The `:write-to`, `:write-json-to`,
+ and `:write-csv-to` commands will also write their output to the terminal
+ when passed `-` as the file name. This mode can be useful for copying
+ plain text lines to the clipboard.
+* (OS X) Text search strings are copied to the system's "find" clipboard.
+ Also, when starting a new search, the current value in the "find"
+ clipboard can be tab-completed.
+
+## lnav v0.7.1
+
+Features:
+* Added an `environ` SQL table that reflects lnav's environment
+ variables. The table can be read and written to using SQL
+ `SELECT`, `INSERT`, `UPDATE`, and `DELETE` statements. Setting
+ variables can be a way to use SQL query results in lnav commands.
+* Added a `jget()` SQLite function that can extract fields from a JSON-
+ encoded value.
+* Added log formats for the OpenAM identity provider.
+* Added a `:clear-highlight` command to clear previous calls to the
+ `:highlight` command.
+* Fixed some performance bugs in indexing JSON log formats. Loading
+ times should be at least five times faster.
+* Filtering performance should be improved so that enabling/disabling
+ filters should be almost instantaneous.
+* The `:filter-in`, `:filter-out`, and `:highlight` commands now support
+ tab-completion of text in the current view.
+* Add a `-i` flag that installs format files in: `~/.lnav/formats/installed`
+
+## lnav v0.7.0
+
+Features:
+* Add the '.schema' SQL command to open a view that displays the schema
+ for the internal tables and any attached databases. If lnav was only
+ executed with a SQLite database and no text files, this view will open
+ by default.
+* The scroll bar now indicates the location of errors/warnings, search
+ hits, and bookmarks.
+* The xterm title is update to reflect the file name for the top line
+ in the view.
+* Added a "headless" mode so that you can execute commands and run SQL
+ queries from the command-line without having to do it from the curses
+ UI.
+* When doing a search or SQL query, any text that is currently being
+ displayed can be tab-completed.
+* The `-H` option was added so you can view the internal help text.
+* Added the 'g/G' hotkeys to move to the top/bottom of the file.
+* Added a `log_mark` column to the log tables that indicates whether or
+ not a log message is bookmarked. The field is writable, so you can
+ bookmark lines using an SQL UPDATE query.
+* Added syntax-highlighting when editing SQL queries or search regexes.
+* Added a `:write-json-to` command that writes the result of a SQL query
+ to a JSON-formatted file.
+* The "elapsed time" column now uses red/green coloring to indicate
+ sharp changes in the message rate.
+* Added a `:set-min-log-level` command to filter out log messages that
+ are below a given level.
+
+Fixes:
+* Performance improvements.
+* Multi-line filtering has been fixed.
+* A collator has been added to the log_level column in the log tables
+ so that you can write expressions like `log_level > 'warning'`.
+* The log_time datetime format now matches what is returned by
+ `datetime('now')` so that collating works correctly.
+* If a search string is not valid PCRE syntax, a search is done for
+ the exact string instead of just returning an error.
+* Static-linking has been cleaned up.
+* OpenSSL is no longer a requirement.
+* Alpha support for Windows/cygwin.
+* Environment variables can now be accessed in SQL queries using
+ the syntax: `$VAR_NAME`
+* An internal log is kept and written out on a crash.
+* Partition bookmarks are now tracked separately from regular user
+ bookmarks. You can start a partition with the 'partition-name'
+ command and remove it with the 'clear-partition' command.
+* Improved display of possible matches during tab-completion in the
+ command-prompt. The matches are now shown in a separate view and
+ pressing tab repeatedly will scroll through the view.
+* The "open" command now does shell word expansion for file names.
+* More config directory paths have been added: `/etc/lnav`,
+ `$prefix/etc/lnav`, and directories passed on the command-line
+ with `-I`.
+
+## lnav v0.6.2
+
+Features:
+* Word-wrap support.
+
+Fixes:
+* Fix some OS X Mavericks build/runtime issues.
+
+## lnav v0.6.1
+Features:
+* Support for JSON-encoded log files.
+
+Fixes:
+* Some minor fixes and performance improvements.
+

+* UI improvements, support for 256 color terminals
+
+## lnav v0.5.1
+
+Features:
+* Added the `-t` and `-w` options which can be used to prepend a
+ timestamp to any data piped in on stdin and to specify a file to
+ write the contents of stdin to.
+
+Fixes:
+* Cleanup for packaging.
+
+## lnav v0.5.0
+
+Features:
+* Files can be specified on the command-line using wildcards so that

+* Copying to the clipboard on OS X is now supported.
+* Many bug fixes.
+
+## lnav v0.4.0
+
+Features:
+* Files that are not recognized as containing log messages have been
+ broken out to a separate text files view. You can flip between the
+ log view and the text file view with the `t` hotkey. When viewing
+ text files, the `f` hotkey will switch between files.
+* Files compressed with bzip2 are recognized and decompressed on the
+ fly.
+* Added a "session" file and command for storing commands that should
+ be executed on startup. For example, if you always want some
+ highlighting to be done, you can add that command to the session
+ file.
+
+Fixes:
+* Add some more log file formats for generic log files.
+* Performance improvements for compressed files.
+* Works on OS X now.
+
+## lnav v0.3.0
+
+Changes:
+* The hotkey for the SQL view was changed to `v` and `V` from '.'.
+
+Features:
+* You can now switch between the SQL result view and the log view while
+ keeping the top of the views in sync with the `log_line` column.
+
+Fixes:
+* The `log_line` column is no longer included in the SQL result view's
+ stacked bar graph.
+* Added a "warnings" count to the histogram view.

+LNAV
+----
+
+The log file navigator, lnav, is an enhanced log file viewer that
+takes advantage of any semantic information that can be gleaned from
+the files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+
+
+PREREQUISITES
+-------------
+
+The following software packages are required to build/run lnav:
+
+ gcc/clang - A C++14-compatible compiler.
+ libpcre2 - The Perl Compatible Regular Expression v2 (PCRE2) library.
+ sqlite - The SQLite database engine. Version 3.9.0 or higher is required.
+ ncurses - The ncurses text UI library.
+ readline - The readline line editing library.
+ zlib - The zlib compression library.
+ bz2 - The bzip2 compression library.
+ re2c - The re2c scanner generator.
+ libcurl - The cURL library for downloading files from URLs. Version
+ 7.23.0 or higher is required.
+ libarchive - The libarchive library for opening archive files, like zip/tgz.
+ wireshark - The 'tshark' program is used to interpret pcap files.
+
+
+INSTALLATION
+------------
+
+Lnav follows the usual GNU style for configuring and installing software:
+
+Run "./autogen.sh" if compiling from a cloned repository.
+
+ $ ./configure
+ $ make
+ $ sudo make install
+
+
+USING
+-----
+
+The only file installed is the executable, "lnav". You can execute it
+with no arguments to view the default set of files:
+
+ $ lnav

+
+# LNAV -- The Logfile Navigator
+
+The Log File Navigator, **lnav** for short, is an advanced log file viewer
+for the small-scale. It is a terminal application that can understand
+your log files and make it easy for you to find problems with little to
+no setup.
+
+## Screenshot
+
+The following screenshot shows a syslog file. Log lines are displayed with
+highlights. Errors are red and warnings are yellow.
+
+[![Screenshot](docs/assets/images/lnav-syslog-thumb.png)](docs/assets/images/lnav-syslog.png)
+
+## Features
+
+- Log messages from different files are collated together into a single view
+- Automatic detection of log format
+- Automatic decompression of GZip and BZip2 files
+- Filter log messages based on regular expressions
+- Use SQL to analyze your logs
+- And more...
+
+## Installation
+
+[Download a statically-linked binary for Linux/MacOS from the release page](https://github.com/tstack/lnav/releases/latest#release-artifacts)
+
+## Usage
+
+The only file installed is the executable, `lnav`. You can execute it
+with no arguments to view the default set of files:
+
+```
+$ lnav
+```
+
+You can view all the syslog messages by running:
+
+```
+$ lnav /var/log/messages*
+```
+
+### Usage with `systemd-journald`
+
+On systems running `systemd-journald`, you can use `lnav` as the pager:
+
+```
+$ journalctl | lnav
+```
+
+or in follow mode:
+
+```
+$ journalctl -f | lnav
+```
+
+Since `journalctl`'s default output format omits the year, if you are
+viewing logs which span multiple years you will need to change the
+output format to include the year, otherwise `lnav` gets confused:
+
+```
+$ journalctl -o short-iso | lnav
+```
+
+It is also possible to use `journalctl`'s json output format and `lnav`
+will make use of additional fields such as PRIORITY and \_SYSTEMD_UNIT:
+
+```
+$ journalctl -o json | lnav
+```
+
+In case some MESSAGE fields contain special characters such as
+ANSI color codes which are considered as unprintable by journalctl,
+specifying `journalctl`'s `-a` option might be preferable in order
+to output those messages still in a non-binary representation:
+
+```
+$ journalctl -a -o json | lnav
+```
+
+If using systemd v236 or newer, the output fields can be limited to
+the ones actually recognized by `lnav` for increased efficiency:
+
+```
+$ journalctl -o json --output-fields=MESSAGE,PRIORITY,_PID,SYSLOG_IDENTIFIER,_SYSTEMD_UNIT | lnav
+```
+
+If your system has been running for a long time, for increased
+efficiency you may want to limit the number of log lines fed into
+`lnav`, e.g. via `journalctl`'s `-n` or `--since=...` options.
+
+In case of a persistent journal, you may want to limit the number
+of log lines fed into `lnav` via `journalctl`'s `-b` option.

+# CHANGES:
+#
+# 2012-01-31, Lars Bilke
+# - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg
+# - Added support for Clang.
+# - Some additional usage instructions.
+#
+# 2016-02-03, Lars Bilke
+# - Refactored functions to use named parameters
+#
+# 2017-06-02, Lars Bilke
+# - Merged with modified version from github.com/ufz/ogs
+#
+# 2019-05-06, Anatolii Kurotych
+# - Remove unnecessary --coverage flag
+#
+# 2019-12-13, FeRD (Frank Dana)
+# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
+# of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
+# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
+# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
+# - Set lcov basedir with -b argument
+# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
+# overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
+# - Delete output dir, .info file on 'make clean'
+# - Remove Python detection, since version mismatches will break gcovr
+# - Minor cleanup (lowercase function names, update examples...)
+#
+# 2019-12-19, FeRD (Frank Dana)
+# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
+#
+# 2020-01-19, Bob Apthorpe
+# - Added gfortran support
+#
+# 2020-02-17, FeRD (Frank Dana)
+# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
+# in EXCLUDEs, and remove manual escaping from gcovr targets
+#
+# USAGE:
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
+# using a CMake option() to enable it just optionally):
+# include(CodeCoverage)
+#
+# 3. Append necessary compiler flags:
+# append_coverage_compiler_flags()
+#
+# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
+#
+# 4. If you need to exclude additional directories from the report, specify them
+# using full paths in the COVERAGE_EXCLUDES variable before calling
+# setup_target_for_coverage_*().
+# Example:
+# set(COVERAGE_EXCLUDES
+# '${PROJECT_SOURCE_DIR}/src/dir1/*'
+# '/path/to/my/src/dir2/*')
+# Or, use the EXCLUDE argument to setup_target_for_coverage_*().
+# Example:
+# setup_target_for_coverage_lcov(
+# NAME coverage
+# EXECUTABLE testrunner
+# EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
+#
+# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
+# relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
+# Example:
+# set(COVERAGE_EXCLUDES "dir1/*")
+# setup_target_for_coverage_gcovr_html(
+# NAME coverage
+# EXECUTABLE testrunner
+# BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
+# EXCLUDE "dir2/*")
+#
+# 5. Use the functions described below to create a custom make target which
+# runs your test executable and produces a code coverage report.
+#
+# 6. Build a Debug build:
+# cmake -DCMAKE_BUILD_TYPE=Debug ..
+# make
+# make my_coverage_target
+#

+
+## Single Log View
+
+All log file contents are merged into a single view based on message timestamps.
+You no longer need to manually correlate timestamps across multiple windows or
+figure out the order in which to view rotated log files. The color bars on the
+left-hand side help to show which file a message belongs to.
+
+![Screenshot of lnav showing messages from multiple files](/assets/images/lnav-multi-file2.png)
+
+## Automatic Log Format Detection
+
+The log message format is automatically determined by lnav while scanning your
+files. The following formats are built in by default:
+
+* Common Web Access Log format
+* CUPS page_log
+* Syslog
+* Glog
+* VMware ESXi/vCenter Logs
+* dpkg.log
+* uwsgi
+* "Generic" - Any message that starts with a timestamp
+* Strace
+* sudo
+
+GZIP'ed and BZIP2'ed files are also detected automatically and decompressed on-the-fly.
+
+## Filters
+
+Display only lines that match or do not match a set of regular expressions.
+Useful for removing extraneous log lines that you are not interested in.
+
+## Timeline View
+
+The timeline view shows a histogram of messages over time. The number of
+warnings and errors are highlighted in the display so that you can easily see
+where problems have occurred. Once you have found a period of time that is of
+interest, a key-press will take you back to the log message view at the
+corresponding time.
+
+![Screenshot of timeline view](/assets/images/lnav-hist.png)
+
+## Pretty-Print View
+
+The pretty-print view will reformat structured data, like XML or JSON, so that
+it is easier to read. Simply press SHIFT+P in the log view to have all the
+currently displayed lines pretty-printed.
+
+The following screenshot shows an XML blob with no indentation:
+
+![A flat blob of XML](/assets/images/lnav-before-pretty.png)
+
+After pressing SHIFT+P, the XML is pretty-printed for easier viewing:
+
+![A pretty-printed blob of XML](/assets/images/lnav-after-pretty.png)
+
+## Query Logs Using SQL
+
+Log files are directly used as the backing for SQLite virtual tables. This
+means you can perform queries on messages without having to load the data into
+an SQL database. For example, the screenshot below shows the result of
+running the following query against an Apache access_log file:
+
+```sql
+SELECT c_ip, count(*), sum(sc_bytes) AS total FROM access_log
+ GROUP BY c_ip ORDER BY total DESC;
+```
+
+![The results of a SQL query](/assets/images/lnav-query.png)
+
+## "Live" Operation
+
+Searches are done as you type; new log lines are automatically loaded and
+searched as they are added; filters apply to lines as they are loaded; and, SQL
+queries are checked for correctness as you type.
+
+## Themes
+
+The UI can be [customized through themes](https://lnav.readthedocs.io/en/latest/config.html#theme-definitions).
+
+![Animation of the UI cycling through themes](/assets/images/lnav-theme-cycle.gif)
+
+## Syntax Highlighting
+
+Errors and warnings are colored in red and yellow, respectively. Highlights are
+also applied to: SQL keywords, XML tags, file and line numbers in Java
+backtraces, and quoted strings. The search and SQL query prompt are also
+highlighted as you type, making it easier to see errors and matching brackets.
+
+![Animation of syntax highlighting](/assets/images/lnav-syntax-highlight.gif)
+
+## Tab-completion
+
+The command prompt supports tab-completion for almost all operations. For
+example, when doing a search, you can tab-complete words that are displayed on
+screen rather than having to do a copy & paste.
+
+![Animation of TAB-completion](/assets/images/lnav-tab-complete.gif)
+
+## Custom Keymaps
+
+[Hotkeys can be customized](https://lnav.readthedocs.io/en/latest/config.html#keymap-definitions)
+to run lnav commands or scripts.
+
+## Sessions
+
+Session information is saved automatically and restored when you are viewing the
+same set of files. The current location in files, bookmarks, and applied filters
+are all saved as part of the session.
+
+## Headless Mode
+
+The log processing features of lnav can be used in scripts if you have a canned
+set of operations or queries that you want to perform regularly. You can enable
+headless mode with the '-n' switch on the command-line and then use the '-c'
+flag to specify the commands or queries you want to execute. For example, to get
+the top 10 client IP addresses from an apache access log file and write the
+results to standard out in CSV format:
+
+```console
+$ lnav -n \
+ -c ';SELECT c_ip, count(*) AS total FROM access_log GROUP BY c_ip ORDER BY total DESC LIMIT 10' \
+ -c ':write-csv-to -' \
+ access.log
+
+c_ip,total
+10.208.110.176,2989570
+10.178.4.102,11183
+10.32.110.197,2020
+10.29.165.250,443

+These tutorials are provided to help you learn how **lnav** works
+without having to install anything. They are running on a shared
+[fly.io](https://fly.io) instance, so please be kind.
+
+The tutorials are implemented using features in **lnav** and not
+built in to the code itself. The tutorial text is
+[markdown](https://docs.lnav.org/en/latest/ui.html#markdown),
+the logic is written [SQL](https://docs.lnav.org/en/latest/sqlext.html),
+and the reactions are triggered through
+[events](https://docs.lnav.org/en/latest/events.html).

+title: "Support for JSON-encoded logs in v0.6.1"
+date: 2013-09-10 00:00:00
+excerpt: Turning JSON barf into something readable.
+---
+
+Making logs easily digestible by machines is becoming a concern as tools like
+elasticsearch become more popular. One of the popular strategies is to encode
+the whole log message in JSON and then write that as a single line to a file.
+For example:
+
+```json
+{"time": "2013-09-04T23:55:09.274041Z", "level" : "INFO", "body" : "Hello, World!" }
+{"time": "2013-09-04T23:56:00.285224Z", "level" : "ERROR", "body" : "Something terrible has happened!", "tb": " foo.c:12\n bar.y:33" }
+```
+
+Unfortunately, what is good for a machine is not so great for a human. To try to
+improve the situation, the latest release of lnav includes support for parsing
+JSON log messages and transforming them on-the-fly. The display format is
+specified in a log format configuration and can specify which fields should be
+displayed on the main message line. Any unused fields that are found in the
+message will be displayed below the main field so you don't miss anything.
+
+The above log lines can be transformed using the following format configuration:
+
+```json
+{
+ "json_ex_log": {
+ "title": "Example JSON Log",
+ "description": "An example log format configuration for JSON logs",
+ "json": true,
+ "file-pattern": "test-log\\.json.*",
+ "level-field": "level",
+ "line-format": [
+ {
+ "field": "time"
+ },
+ " ",
+ {
+ "field": "body"
+ }
+ ]
+ }
+}
+```
+
+After copying this config to `~/.lnav/formats/test/format.json`, the log messages
+will look like this when viewed in lnav:
+
+```
+2013-09-04T23:55:09.274041Z Hello, World!
+2013-09-04T23:56:00.285224Z Something terrible has happened!
+ tb: foo.c:12
+ tb: bar.y:33
+```

+The [first commit](https://github.com/tstack/lnav/commit/b4ec432515e95e86ec9d711833b8cb34d0912546)
+to the [lnav repository](https://github.com/tstack/lnav) was four years ago
+today! I started working on lnav a couple of years before that, but this was

+title: "Competing with 'tail -f'"
+date: 2013-09-10 00:00:00
+excerpt: The standard utilities are tough competition.
+---
+
+Probably the toughest competition for lnav is the standard Unix utilities like
+tail, grep, less, and emacs/vim. It can be hard trying to convince people that
+these built-in commands that they've used for forever can be improved upon. The
+advanced features of lnav might even work against it since folks are expecting
+to have to learn a bunch of stuff to see any benefits.
+
+The reality is that there are quite a few "passive" features in lnav that can
+provide value with no effort required by the user. For example, lnav can easily
+replace 'tail -f', it's even shorter to type! Beyond the basic task of
+displaying new lines appended to a log file, you also get to see log messages
+from multiple files interleaved, the ability to scroll backwards, syntax
+highlighting, live searching, and so on. These basic features do not have the
+same "wow" factor as executing a SQL query over data automatically extracted
+from a log file, but they're the features that get used 90% of the time.
+
+Anyways, I think I'm gaining a new appreciation for marketing/sales...

+excerpt: Packing more information into the right scrollbar.
+---
+
+I've made some changes to the scrollbar that is shown on the right side of the
+display based on some feedback from users. The scroll area now has a single
+vertical line extending from the top to the bottom. Previously, this area would
+show log message characters and it wasn't very clear that the scroll bar
+existed. The line is colored based whether there are errors or warnings in that
+part of the log. The coloring should make it easier to see the distribution of
+errors across the whole log. Similarly, there are notches added to the left and
+right side of the line to show search hits and bookmarks, respectively. See the
+following screenshot to get an idea of what it looks like:
+
+![Screenshot of the redesigned scrollbar](/assets/images/scrollbar-change-2.png)
+
+These changes are currently only in the latest code from git. I'll be playing
+with things a bit more before making a release.

+Copying text to the clipboard can be done by marking lines with the

+accept `/dev/clipboard` as a way to write to the clipboard. However, if the
+native clipboard isn't supported, or you're on an SSH connection, you can
+now switch to "lo-fi" mode. In "lo-fi" mode, lnav drops out of the curses
+display and prints the raw text to the terminal. You can switch to "lo-fi"
+mode in a view by pressing `CTRL-L`. For commands, you can use a dash `-`
+to switch to "lo-fi" and print to standard out.

+excerpt: Automatically reformat structured data with "SHIFT+P".
+---
+
+I wanted to call out the pretty-print feature in the latest release of lnav.
+This idea came from a coworker of Suresh who was having a hard time trying to
+read some unformatted XML in a log. They wanted the XML pretty-printed and were
+hoping that could be done by just piping the message to xmlpp or the like. So,
+first we implemented the 'pipe-to' and 'pipe-line-to' commands that will let you
+pipe log messages to a command and then display the result inside of lnav. That
+worked well enough, but pretty-printing is such a frequent operation that having
+to execute a command was kind of a pain. It would also be nice if it worked for
+a variety of text, like JSON or Python data. The solution we came up with was to
+leverage the existing code for parsing log messages to create a simple
+pretty-printer that should work for most data formats. Another benefit is that
+the log message does not have to be well-formed for the printer to work, any
+leading or trailing garbage shouldn't confuse things.
+
+As an example, here is a screenshot of the log message with the unformatted XML
+text with word-wrapping turned on:
+
+![Screenshot of raw XML](/assets/images/lnav-before-pretty.png)
+
+That's not very easy to read and it's hard to figure out the structure of the
+message. Now, here is that same message after pressing SHIFT+P to switch to the
+pretty-print view of lnav:
+
+![Screenshot of pretty-printed XML](/assets/images/lnav-after-pretty.png)
+
+The XML text is indented nicely and the usual syntax highlighting is applied.
+Also notice that lnav will automatically try to lookup the DNS name for IP
+addresses. Overall, I think it's a major improvement over the raw view.
+
+This is a pretty simple feature but I have found it quite useful in the couple
+weeks that it has been implemented. It's so useful that I'm kicking myself for
+not having thought of it before.

+XML snippets in log messages can now be queried using the

+For example, given following XML document:
+
+```xml
+<msg>Hello, World!</msg>
+```
+

+
+Of course, you won't typically be passing XML values as string literals, you
+will be extracting them from log messages. Assuming your log format already
+extracts the XML data, you can do a `SELECT` on the log format table and join

+---
+
+*(This change is in [**v0.10.0+**](https://github.com/tstack/lnav/releases/tag/v0.10.0))*
+
+One of the new features in the upcoming v0.10.0 release of lnav is support
+for tailing log files on remote hosts via SSH. This feature allows you to
+view local files and files from multiple remote hosts alongside each other
+in the log view. The only setup required is to ensure the machines can be
+accessed via SSH without any interaction, meaning the host key must have
+been previously accepted and public key authentication configured. Opening
+a remote file is then simply a matter of specifying the location using the
+common scp syntax (i.e. `user@host:/path/to/file`).
+
+When lnav accesses a remote host, it transfers an agent (called the
+"tailer") to the host to handle file system requests from lnav. The agent
+is an [αcτµαlly pδrταblε εxεcµταblε](https://justine.lol/ape.html) that
+should run on most X86 Operating Systems. The agent will monitor the
+files of interest and synchronize their contents back to the host machine.
+In addition, the agent can be used to satisfy interactive requests for
+TAB-completion of remote file paths and previewing directory and file
+contents.
+
+The following asciicast shows lnav opening log files on MacOS and FreeBSD:

+title: Integration with regex101.com
+excerpt: Create/edit format files using regex101.com
+---
+
+*(This change will be in the upcoming v0.11.0 release)*
+
+Creating and updating format files for **lnav** can be a bit tedious and
+error-prone. To help streamline the process, an integration with regex101.com
+has been added. Now, you can create regular expressions for plaintext log
+files on https://regex101.com and then create a skeleton format file with a
+simple command. If you already have a format file that needs to be updated,
+you can push the regexes up to regex101, edit them with their interface, and
+then pull the changes back down as a format patch file.
+
+To further improve the experience of developing with format files, there is
+also work underway to improve error messages. Many messages should be clearer,
+more context is provided, and they should look nicer as well. For example, the
+following error is displayed when a format regex is not valid:
+
+![Screenshot of an error message](/assets/images/lnav-invalid-regex-error.png)
+
+## Management CLI
+
+The regex101 integration can be accessed through the new "management-mode CLI".
+This mode can be accessed by passing `-m` as the first option to **lnav**. The
+management CLI is organized as a series of nested commands. If you're not sure
+what to do at a given level, run the command as-is and the CLI should print out
+help text to guide you through the hierarchy of commands and required
+parameters.
+
+### Create a format from a regular expression
+
+The `regex101 import` command can be used to import a regular expression from
+regex101.com and create or patch a format file. The command takes the URL of
+the regex, the format name, and the name of the regex in the log format (
+defaults to "std" if not given). For example, the following command can be used
+to import the regex at "https://regex101.com/r/zpEnjV/2" into the format named "
+re101_example_log":
+
+```console
+$ lnav -m regex101 import https://regex101.com/r/zpEnjV/2 re101_example_log
+```
+
+If the import was successful, the path to the skeleton format file will be
+printed. You will most likely need to edit the file to fill in more details
+about your log format.
+
+### Editing an existing regular expression
+
+If you have a log format with a regex that needs to be updated, you can push
+the regex to regex101.com for editing with a command like (replace
+"myformat_log"/"std" with the name of your format and regex):
+
+```console
+$ lnav -m format myformat_log regex std regex101 push
+```
+
+Along with the regex, the format's samples will be added to the entry to ensure
+changes won't break existing matches. If the push was successful, the URL for
+the new regex101.com entry will be printed out. You can use that URL to edit the
+regex to your needs. Once you're done editing the regex, you can pull the
+changes down to a "patch" file using the following command:
+
+```console
+$ lnav -m format myformat_log regex std regex101 pull
+```
+
+The patch file will be evaluated after the original format file and override
+the values from the original. Once you are satisfied with the changes, you
+can move the contents of the patch file to the original file and delete the
+patch.

+title: Pretty error messages
+excerpt: Error message improvements
+---
+
+*(This change will be in the upcoming v0.11.0 release)*
+
+Taking a page from compilers like rustc, I've spent some time
+improving error messages to make them look nicer and be more
+helpful. Fortunately, SQLite has improved their error reporting
+as well by adding
+[sqlite3_error_offset()](http://sqlite.com/c3ref/errcode.html).
+This function can point to the part of the SQL statement that
+was in error. As an example of the improvement, a SQL file
+that contained the following content:
+
+```sql
+
+-- This is a test
+SELECT abc),
+rtrim(def)
+FROM mytable;
+```
+
+Would report an error like the following on startup in v0.10.1:
+
+```text
+error:/Users/tstack/.config/lnav/formats/installed/test.sql:2:near ")": syntax error
+```
+
+Now, you will get a clearer error message with a syntax-highlighted
+code snippet and a pointer to the part of the code that has the
+problem:
+
+![Screenshot of a SQL error](/assets/images/lnav-sql-error-msg.png)

+time or when input is received. Here is an example showing an error
+for an invalid regular expression:

+
+*(This change will be in the upcoming v0.11.0 release)*
+
+As part of the effort to polish the lnav TUI, I wanted to make the builtin
+help text look a bit nicer. The current help text is a plain text file with
+some ANSI escape sequences for colors. It's not easy to write or read. Since
+Markdown has become a dominant way to write this type of document, I figured
+I could use that and have the side benefit of allowing lnav to read Markdown
+docs. Fortunately, the [MD4C](https://github.com/mity/md4c) library exists.
+This library provides a nice event-driven parser for documents instead of
+just converting directly to HTML. In addition, document structure is now
+shown/navigable through the new breadcrumb bar at the top. I think the
+result is pretty nice:
+
+<script id="asciicast-2hx3UiyzOHQXBQOBf31ztKvHc"
+ src="https://asciinema.org/a/2hx3UiyzOHQXBQOBf31ztKvHc.js"
+ async>
+</script>
+
+## Viewing Markdown Files
+
+Files with an `.md` suffix will be considered as Markdown and will be
+parsed as such. As an example, here is lnav displaying its README.md file:
+
+<script id="asciicast-iw4rwddZNGCe3v8DyOfItERG9"
+ src="https://asciinema.org/a/iw4rwddZNGCe3v8DyOfItERG9.js"
+ async>

+title: Playground and Tutorial
+excerpt: Try lnav without having to install anything
+---
+
+To make it easier to try out **lnav**, I've deployed an ssh-based playground
+and tutorial. You can SSH as follows to try them out:
+
+```console
+$ ssh playground@demo.lnav.org
+$ ssh tutorial1@demo.lnav.org
+```
+
+<script id="asciicast-HiiUMMmRKZh0uCVKm1Uw8WLlw"
+ src="https://asciinema.org/a/HiiUMMmRKZh0uCVKm1Uw8WLlw.js"
+ async>
+</script>
+
+The playground has a couple of example logs to play with. The tutorial
+tries to guide you through the basics of navigating log files with lnav.
+The server is running on the free-tier of [fly.io](https://fly.io), so
+please be kind.
+
+This effort was inspired by the `git.charm.sh` SSH server and by the
+[fasterthanli.me](https://fasterthanli.me/articles/remote-development-with-rust-on-fly-io)
+post on doing remote development on fly.io.

+title: VSCode Extension for lnav
+excerpt: Syntax highlighting for lnav scripts
+---
+
+I've published a simple [Visual Studio Code extension for lnav](
+https://marketplace.visualstudio.com/items?itemName=lnav.lnav)
+that adds syntax highlighting for scripts. The following is a
+screenshot showing the `dhclient-summary.lnav` script that is
+builtin:
+
+![Screenshot of an lnav script](/assets/images/lnav-vscode-extension.png)
+
+The lnav commands, those prefixed with colons, are marked as
+keywords and the SQL blocks are treated as an embedded language
+and highlighted accordingly.
+
+If people find this useful, we can take it further and add
+support for running the current script/snippet in a new lnav
+process or even talking to an existing one.

+
+Command Line Interface
+======================
+
+There are two command-line interfaces provided by **lnav**, one for viewing
+files and one for managing **lnav**'s configuration. The file viewing mode is
+the default and is all that most people will need. The management mode can
+be useful for those that are developing log file formats and is activated by
+passing the :option:`-m` option as the first argument.
+
+File Viewing Mode
+-----------------
+
+The following options can be used when starting **lnav**. There are not
+many flags because the majority of the functionality is accessed using
+the :option:`-c` option to execute :ref:`commands<commands>` or
+:ref:`SQL queries<sql-ext>`.
+
+Options
+^^^^^^^
+
+.. option:: -h
+
+ Print these command-line options and exit.
+
+.. option:: -H
+
+ Start lnav and switch to the help view.
+
+.. option:: -C
+
+ Check the given files against the configuration, report any errors, and
+ exit. This option can be helpful for validating that a log format is
+ well-formed.
+
+.. option:: -c <command>
+
+ Execute the given lnav command, SQL query, or lnav script. The
+ argument must be prefixed with the character used to enter the prompt
+ to distinguish between the different types (i.e. ':', ';', '|').
+ This option can be given multiple times.
+
+.. option:: -f <path>
+
+ Execute the given command file. This option can be given multiple times.
+
+.. option:: -I <path>
+
+ Add a configuration directory.
+
+.. option:: -i
+
+ Install the format files in the :file:`.lnav/formats/` directory.
+ Individual files will be installed in the :file:`installed`

+
+Management Mode (v0.11.0+)
+--------------------------
+
+The management CLI mode provides functionality for query **lnav**'s log
+format definitions.
+
+Options
+^^^^^^^
+
+.. option:: -m
+
+ Switch to management mode. This must be the first option passed on the
+ command-line.
+
+Subcommands
+^^^^^^^^^^^
+
+.. option:: regex101 import <regex101-url> <format-name> [<regex-name>]
+
+ Convert a regex101.com entry into a skeleton log format file.
+
+.. option:: format <format-name> regex <regex-name> push
+
+ Push a log format regular expression to regex101.com .
+
+.. option:: format <format-name> regex <regex-name> pull
+
+ Pull changes to a regex that was previously pushed to regex101.com .
+
+Environment Variables
+---------------------
+
+.. envvar:: XDG_CONFIG_HOME
+
+ If this variable is set, lnav will use this directory to store its
+ configuration in a sub-directory named :file:`lnav`.
+
+.. envvar:: HOME
+
+ If :envvar:`XDG_CONFIG_HOME` is not set, lnav will use this directory
+ to store its configuration in a sub-directory named :file:`.lnav`.
+
+.. envvar:: APPDATA
+
+ On Windows, lnav will use this directory instead of HOME
+ to store its configuration in a sub-directory named :file:`.lnav`.
+
+.. envvar:: TZ
+
+ The timezone setting is used in some log formats to convert UTC timestamps
+ to the local timezone.
+
+
+Examples
+--------
+
+ To load and follow the system syslog file:
+
+ .. prompt:: bash
+
+ lnav
+
+ To load all of the files in :file:`/var/log`:
+
+ .. prompt:: bash
+
+ lnav /var/log
+
+ To watch the output of make with timestamps prepended:
+
+ .. prompt:: bash
+
+ make 2>&1 | lnav -t

+
+Commands
+========
+
+Commands provide access to some of the more advanced features in **lnav**, like
+:ref:`filtering<filtering>` and
+:ref:`"search tables"<search_tables>`. You can activate the command
+prompt by pressing the :kbd:`:` key. At the prompt, you can start typing
+in the desired command and/or double-tap :kbd:`TAB` to activate
+auto-completion and show the available commands. To guide you in the usage of
+the commands, a help window will appear above the command prompt with an
+explanation of the command and its parameters (if it has any). For example,
+the screenshot below shows the help for the :code:`:open` command:
+
+.. figure:: open-help.png
+ :align: center
+ :figwidth: 50%
+
+ Screenshot of the online help for the :code:`:open` command.
+
+In addition to online help, many commands provide a preview of the effects that
+the command will have. This preview will activate shortly after you have
+finished typing, but before you have pressed :kbd:`Enter` to execute the
+command. For example, the :code:`:open` command will show a preview of the
+first few lines of the file given as its argument:
+
+.. figure:: open-preview.png
+ :align: center
+
+ Screenshot of the preview shown for the :code:`:open` command.
+
+The :lnavcmd:`:filter-out pattern` command is another instance where the preview behavior
+can help you craft the correct command-line. This command takes a PCRE2 regular
+expression that specifies the log messages that should be filtered out of the
+view. The preview for this command will highlight the portion of the log
+messages that match the expression in red. Thus, you can be certain that the
+regular expression is matching the log messages you are interested in before
+committing the filter. The following screenshot shows an example of this
+preview behavior for the string "launchd":
+
+.. figure:: filter-out-preview.png
+ :align: center
+
+ Screenshot showing the preview for the :code:`:filter-out` command.
+
+Any errors detected during preview will be shown in the status bar right above
+the command prompt. For example, an attempt to open an unknown file will show
+an error message in the status bar, like so:
+
+.. figure:: open-error.png
+ :align: center
+
+ Screenshot of the error shown when trying to open a non-existent file.
+
+.. tip::
+
+ Note that almost all commands support TAB-completion for their arguments.
+ So, if you are in doubt as to what to type for an argument, you can double-
+ tap the :kbd:`TAB` key to get suggestions. For example, the
+ TAB-completion for the :code:`filter-in` command will suggest words that are
+ currently displayed in the view.
+
+.. note:: The following commands can be disabled by setting the ``LNAVSECURE``
+ environment variable before executing the **lnav** binary:
+
+ - :code:`:open`
+ - :code:`:pipe-to`
+ - :code:`:pipe-line-to`
+ - :code:`:write-*-to`
+
+ This makes it easier to run **lnav** in restricted environments without the
+ risk of privilege escalation.
+
+I/O Commands
+------------
+
+Anonymization
+^^^^^^^^^^^^^
+
+Anonymization is the process of removing identifying information from content
+to make it safer for sharing with others. For example, an IP address can
+often be used to uniquely identify an entity. Substituting all instances of
+a particular IP with the same dummy value would remove the identifying data
+without losing statistical accuracy. **lnav** has built-in support for
+anonymization through the :code:`--anonymize` flag on the :code:`:write-*`
+collection of commands. While the anonymization process should catch most
+
+ :IPv4 Addresses: Are replaced with addresses in the :code:`10.0.0.0/8` range.
+
+ :IPv6 Addresses: Are replaced with addresses in the :code:`2001:db8::/32` range.
+
+ :URL User Names: Are replaced with a random animal name.
+
+ :URL Passwords: Are replaced with a hash of the input password.
+
+ :URL Hosts: Are replaced with a random name under the example.com domain.
+
+ :URL Paths: Are recursively examined for substitution.
+
+ :URL Query Strings: Are recursively examined for substitution.
+
+ :URL Fragments: Are recursively examined for substitution.
+
+ :Paths: Are recursively examined for substitution.
+
+ :Credit Card Numbers: Are replaced with a 16 digit hash of the input number.
+
+ :MAC Addresses: Are replaced with addresses in the :code:`00:00:5E:00:53:00` range.
+
+ :Hex Dumps: Are replaced with a hash of the input replicated to the size of input.
+
+ :Email User Names: Are replaced with a random animal name.
+
+ :Email Host Names: Are replaced with a random name under the example.com domain.
+
+ :Words: Are replaced with a random word with a matching case style.
+
+ :Quoted Strings: Are recursively examined for substitution.
+
+ :UUID: Are replaced with a hash of the input.
+
+ :XML Attribute Values: Are recursively examined for substitution.

+
+Configuration
+=============
+
+The configuration for **lnav** is stored in the following JSON files in
+:file:`~/.lnav`:
+
+* :file:`config.json` -- Contains local customizations that were done using the
+ :code:`:config` command.
+* :file:`configs/default/*.json` -- The default configuration files that are
+ built into lnav are written to this directory with :file:`.sample` appended.
+ Removing the :file:`.sample` extension and editing the file will allow you to
+ do basic customizations.
+* :file:`configs/installed/*.json` -- Contains configuration files installed
+ using the :option:`-i` flag (e.g. :code:`$ lnav -i /path/to/config.json`).
+* :file:`configs/*/*.json` -- Other directories that contain :file:`*.json`
+ files will be loaded on startup. This structure is convenient for installing
+ **lnav** configurations, like from a git repository.
+
+A valid **lnav** configuration file must contain an object with the
+:code:`$schema` property, like so:
+
+.. code-block:: json
+
+ {
+ "$schema": "https://lnav.org/schemas/config-v1.schema.json"
+ }
+
+.. note::
+
+ Log format definitions are stored separately in the :file:`~/.lnav/formats`
+ directly. See the :ref:`Log Formats<log_formats>` chapter for more
+ information.
+
+
+Options
+-------
+
+The following configuration options can be used to customize the **lnav** UI to
+your liking. The options can be changed using the :code:`:config` command.
+
+.. jsonschema:: ../schemas/config-v1.schema.json#/properties/ui/properties/keymap
+
+.. jsonschema:: ../schemas/config-v1.schema.json#/properties/ui/properties/theme

+
+
+.. _themes:
+
+Theme Definitions
+-----------------
+
+User Interface themes are defined in a JSON configuration file. A theme is
+made up of the style definitions for different types of text in the UI. A
+:ref:`definition<theme_style>` can include the foreground/background colors
+and the bold/underline attributes. The style definitions are broken up into
+multiple categories for the sake of organization. To make it easier to write
+a definition, a theme can define variables that can be referenced as color
+values.
+
+Variables
+^^^^^^^^^
+
+The :code:`vars` object in a theme definition contains the mapping of variable
+names to color values. These variables can be referenced in style definitions
+by prefixing them with a dollar-sign (e.g. :code:`$black`). The following
+variables can also be defined to control the values of the ANSI colors that
+are log messages or plain text:
+
+.. csv-table:: ANSI colors
+ :header: "Variable Name", "ANSI Escape"
+
+ "black", "ESC[30m"
+ "red", "ESC[31m"
+ "green", "ESC[32m"
+ "yellow", "ESC[33m"
+ "blue", "ESC[34m"
+ "magenta", "ESC[35m"
+ "cyan", "ESC[36m"
+ "white", "ESC[37m"
+
+Specifying Colors
+^^^^^^^^^^^^^^^^^
+
+Colors can be specified using hexadecimal notation by starting with a hash
+(e.g. :code:`#aabbcc`) or using a color name as found at
+http://jonasjacek.github.io/colors/. If colors are not specified for a style,
+the values from the :code:`styles/text` definition.
+
+.. note::
+
+ When specifying colors in hexadecimal notation, you do not need to have an

+
+The following example sets the black/background color for text to a dark grey
+using a variable and sets the foreground to an off-white. This theme is
+incomplete, but it works enough to give you an idea of how a theme is defined.
+You can copy the code block, save it to a file in
+:file:`~/.lnav/configs/installed/` and then activate it by executing
+:code:`:config /ui/theme example` in lnav. For a more complete theme
+definition, see one of the definitions built into **lnav**, like

+
+Keymap Definitions
+------------------
+
+Keymaps in **lnav** map a key sequence to a command to execute. When a key is
+pressed, it is converted into a hex-encoded string that is looked up in the
+keymap. The :code:`command` value associated with the entry in the keymap is
+then executed. Note that the "command" can be an **lnav**
+:ref:`command<commands>`, a :ref:`SQL statement/query<sql-ext>`, or an
+**lnav** script. If an :code:`alt-msg` value is included in the entry, the
+bottom-right section of the UI will be updated with the help text.
+
+.. note::
+
+ Not all functionality is available via commands or SQL at the moment. Also,
+ some hotkeys are not implemented via keymaps.
+
+Key Sequence Encoding
+^^^^^^^^^^^^^^^^^^^^^
+
+Key presses are converted into a hex-encoded string that is used to lookup an
+entry in the keymap. Each byte of the keypress value is formatted as an
+:code:`x` followed by the hex-encoding in lowercase. For example, the encoding
+for the £ key would be :code:`xc2xa3`. To make it easier to discover the
+encoding for unassigned keys, **lnav** will print in the command prompt the
+:code:`:config` command and
+`JSON-Pointer <https://tools.ietf.org/html/rfc6901>`_ for assigning a command
+to the key.
+
+.. figure:: key-encoding-prompt.png
+ :align: center
+
+ Screenshot of the command prompt when an unassigned key is pressed.
+
+.. note::
+
+ Since **lnav** is a terminal application, it can only receive keypresses that
+ can be represented as characters or escape sequences. For example, it cannot
+ handle the press of a modifier key.

+
+Log Handling
+------------
+
+The handling of logs is largely determined by the
+:ref:`log file formats<log_formats>`, this section covers options that are not
+specific to a particular format.
+
+Watch Expressions (v0.11.0+)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Watch expressions can be used to fire an event when a log message matches a
+condition. You can then install a listener for these events and trigger an
+action to be performed. For example, to automate filtering based on
+identifiers, a watch expression can match messages that mention the ID and then
+a trigger can install a filter for that ID. Creating a watch expression is
+done by adding an entry into the :code:`/log/watch-expressions` configuration
+tree. For example, to create a watch named "dhcpdiscover" that matches
+DHCPDISCOVER messages from the :code:`dhclient` daemon, you would run the
+following:
+
+.. code-block:: lnav
+
+ :config /log/watch-expressions/dhcpdiscover/expr :log_procname = 'dhclient' AND startswith(:log_body, 'DHCPDISCOVER')
+
+The watch expression can refer to column names in the log message by prefixing
+them with a colon. The expression is evaluated by passing the log message
+fields as bound parameters and not against a table. The easiest way to test
+out an expression is with the :ref:`mark_expr` command, since it will behave
+similarly. After changing the configuration, you'll need to restart lnav
+for the effect to take place. You can then query the :code:`lnav_events`
+table to see any generated
+:code:`https://lnav.org/event-log-msg-detected-v1.schema.json` events from the
+logs that were loaded:
+
+.. code-block:: custsqlite
+
+ ;SELECT * FROM lnav_events
+
+From there, you can create a SQLite trigger on the :code:`lnav_events` table
+that will examine the event contents and perform an action. See the
+:ref:`Events` section for more information on handling events.

+Cookbook
+========
+
+This chapter contains recipes for common tasks that can be done in **lnav**.
+These recipes can be used as a starting point for your own needs after some
+adaptation.
+
+
+Log Formats
+-----------
+
+TBD
+
+Defining a New Format
+^^^^^^^^^^^^^^^^^^^^^
+
+TBD
+
+
+Annotating Logs
+---------------
+
+Log messages can be annotated in a couple of different ways in **lnav** to help
+you get organized.
+
+Create partitions for Linux boots
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When digging through logs that can be broken up into multiple sections,
+**lnav**'s :ref:`partitioning feature<taking_notes>` can be used to keep track
+of which section you are in. For example, if a collection of Linux logs
+covered multiple boots, the following script could be used to create partitions
+for each boot. After the partition name is set for the log messages, the
+current name will show up in the top status bar next to the current time.
+
+.. literalinclude:: ../../src/scripts/partition-by-boot.lnav
+ :language: custsqlite
+ :caption: partition-by-boot.lnav
+ :linenos:
+
+Tagging SSH log messages
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Log messages can be tagged interactively with the :ref:`:tag<tag>` command or
+programmatically using the :ref:`sql-ext`. This example uses a script to
+search for interesting SSH messages and automatically adds an appropriate tag.
+
+.. literalinclude:: ../../example-scripts/tag-ssh-msgs.lnav
+ :language: custsqlite
+ :caption: tag-ssh-msgs.lnav
+ :linenos:
+
+Log Analysis
+------------
+
+Most log analysis within **lnav** is done through the :ref:`sql-ext`. The
+following examples should give you some ideas to start leveraging this
+functionality. One thing to keep in mind is that if a query gets to be too
+large or multiple statements need to be executed, you can create a
+:code:`.lnav` script that contains the statements and execute it using the
+:kbd:`\|` command prompt.
+
+Count client IPs in web access logs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To count the occurrences of an IP in web access logs and order the results
+from highest to lowest:
+
+ .. code-block:: custsqlite
+
+ ;SELECT c_ip, count(*) as hits FROM access_log GROUP BY c_ip ORDER BY hits DESC
+
+
+Show only lines where a numeric field is in a range
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The :ref:`:filter-expr<filter_expr>` command can be used to filter web access
+logs to only show lines where the number of bytes transferred to the client is
+between 10,000 and 40,000 bytes like so:
+
+ .. code-block:: custsqlite
+
+ :filter-expr :sc_bytes BETWEEN 10000 AND 40000
+
+
+Generating a Report
+^^^^^^^^^^^^^^^^^^^
+
+Reports can be generated by writing an **lnav** :ref:`script<scripts>` that
+uses SQL queries and commands to format a document. A basic script can simply
+execute a SQL query that is shown in the DB view. More sophisticated scripts
+can use the following commands to generate customized output for a report:
+
+* The :ref:`:echo<echo>` command to write plain text
+* :ref:`SQL queries<sql-ext>` followed by a "write" command, like
+ :ref:`:write-table-to<write_table_to>`.

+
+Extracting Data
+===============
+
+**Note**: This feature is still in **BETA**, you should expect bugs and
+incompatible changes in the future.
+
+Log messages contain a good deal of useful data, but it's not always easy to get
+at. The log parser built into **lnav** is able to extract data as described by
+:ref:`log_formats` as well as discovering data in plain text messages. This data
+can then be queried and processed using the SQLite front-end that is also
+incorporated into **lnav**. As an example, the following Syslog message from
+:code:`sudo` can be processed to extract several key/value pairs::
+
+ Jul 31 11:42:26 Example-MacBook-Pro.local sudo[87024]: testuser : TTY=ttys004 ; PWD=/Users/testuser/github/lbuild ; USER=root ; COMMAND=/usr/bin/make install
+
+The data that can be extracted by the parser is viewable directly in **lnav**
+by pressing the 'p' key. The results will be shown in an overlay like the
+following::
+
+ Current Time: 2013-07-31T11:42:26.000 Original Time: 2013-07-31T11:42:26.000 Offset: +0.000
+ Known message fields:
+ ├ log_hostname = Example-MacBook-Pro.local
+ ├ log_procname = sudo
+ ├ log_pid = 87024
+ Discovered message fields:
+ ├ col_0 = testuser
+ ├ TTY = ttys004
+ ├ PWD = /Users/testuser/github/lbuild
+ ├ USER = root
+ └ COMMAND = /usr/bin/make install
+
+Notice that the parser has detected pairs of the form '<key>=<value>'. The data
+parser will also look for pairs separated by a colon. If there are no clearly
+demarcated pairs, then the parser will extract anything that looks like data
+values and assign them keys of the form 'col_N'. For example, two data values,
+an IPv4 address and a symbol, will be extracted from the following log
+message::
+
+ Apr 29 08:13:43 sample-centos5 avahi-daemon[2467]: Registering new address record for 10.1.10.62 on eth0.
+
+Since there are no keys for the values in the message, the parser will assign
+'col_0' for the IP address and 'col_1' for the symbol, as seen here::
+
+ Current Time: 2013-04-29T08:13:43.000 Original Time: 2013-04-29T08:13:43.000 Offset: +0.000
+ Known message fields:
+ ├ log_hostname = sample-centos5
+ ├ log_procname = avahi-daemon
+ ├ log_pid = 2467
+ Discovered message fields:
+ ├ col_0 = 10.1.10.62
+ └ col_1 = eth0
+
+Now that you have an idea of how the parser works, you can begin to perform
+queries on the data that is being extracted. The SQLite database engine is
+embedded into **lnav** and its `Virtual Table
+<http://www.sqlite.org/vtab.html>`_ mechanism is used to provide a means to
+process this log data. Each log format has its own table that can be used to
+access all of the loaded messages that are in that format. For accessing log
+message content that is more free-form, like the examples given here, the
+**logline** table can be used. The **logline** table is recreated for each
+query and is based on the format and pairs discovered in the log message at
+the top of the display.
+
+Queries can be performed by pressing the semi-colon (;) key in **lnav**. After
+pressing the key, the overlay showing any known or discovered fields will be
+displayed to give you an idea of what data is available. The query can be any
+`SQL query <http://sqlite.org/lang.html>`_ supported by SQLite. To make
+analysis easier, **lnav** includes many extra functions for processing strings,
+paths, and IP addresses. See :ref:`sql-ext` for more information.
+
+As an example, the simplest query to perform initially would be a "select all",
+like so:
+
+.. code-block:: sql
+
+ SELECT * FROM logline
+
+When this query is run against the second example log message given above, the
+following results are received::
+
+ log_line log_part log_time log_idle_msecs log_level log_hostname log_procname log_pid col_0 col_1

+
+Note that **lnav** is not returning results for all messages that are in this
+syslog file. Rather, it searches for messages that match the format for the
+given line and returns only those messages in results. In this case, that
+format is "Registering new address record for <IP> on <symbol>", which
+corresponds to the parts of the message that were not recognized as data.
+
+More sophisticated queries can be done, of course. For example, to find out the
+frequency of IP addresses mentioned in these messages, you can run:
+
+.. code-block:: sql
+
+ SELECT col_0,count(*) FROM logline GROUP BY col_0
+
+The results for this query are::
+
+ col_0 count(*)
+
+ 10.0.2.15 1
+ 10.1.10.49 2
+ 10.1.10.62 2
+ 10.1.10.64 2
+ 10.1.10.75 6
+ 10.1.10.103 2
+ 10.1.10.111 1
+ fe80::a00:27ff:fe98:7f6e 6
+
+Since this type of query is fairly common, **lnav** includes a "summarize"
+command that will compute the frequencies of identifiers as well as min, max,
+average, median, and standard deviation for number columns. In this case, you
+can run the following to compute the frequencies and return an ordered set of
+results::
+
+ :summarize col_0
+
+
+Recognized Data Types
+---------------------
+
+When searching for data to extract from log messages, **lnav** looks for the
+following set of patterns:
+
+
+Strings
+ Single and double-quoted strings. Example: "The quick brown fox."
+
+URLs
+ URLs that contain the '://' separator. Example: http://example.com
+
+Paths
+ File system paths. Examples: /path/to/file, ./relative/path
+
+MAC Address
+ Ethernet MAC addresses. Example: c4:2c:03:0e:e4:4a
+
+Hex Dumps
+ A colon-separated string of hex numbers. Example: e8:06:88:ff
+
+Date/Time
+ Date and time stamps of the form "YYYY-mm-DD" and "HH:MM:SS".
+
+IP Addresses
+ IPv4 and IPv6 addresses. Examples: 127.0.0.1, fe80::c62c:3ff:fe0e:e44a%en0
+
+UUID
+ The common formatting for 128-bit UUIDs. Example:
+ 0E305E39-F1E9-4DE4-B10B-5829E5DF54D0
+
+Version Numbers
+ Dot-separated version numbers. Example: 3.7.17
+
+Numbers
+ Numbers in base ten, hex, and octal formats. Examples: 1234, 0xbeef, 0777
+
+E-Mail Address
+ Strings that look close to an e-mail address. Example: gary@example.com
+
+Constants
+ Common constants in languages, like: true, false, null, None.
+
+Symbols
+ Words that follow the common conventions for symbols in programming
+ languages. For example, containing all capital letters, or separated
+ by colons. Example: SOME_CONSTANT_VALUE, namespace::value

+Events (v0.11.0+)
+=================
+
+The events mechanism allows **lnav** to be automated based on events that
+occur during processing. For example, filters could be added only when a
+particular log file format is detected instead of always installing them.
+Events are published through the :ref:`lnav_events<table_lnav_events>` SQLite
+table. Reacting to events can be done by creating a SQLite trigger on the
+table and inspecting the content of the event.
+
+Trigger Example
+---------------
+
+The following is an example of a trigger that adds an out filter when a
+syslog file is loaded. You can copy the code into an :file:`.sql` file and
+install it by running :code:`lnav -i my_trigger.sql`.

+Frequently Asked Questions
+==========================
+
+Q: How can I copy & paste without decorations?
+----------------------------------------------
+
+:Answer: There are a few ways to do this:
+
+ * Use the :ref:`bookmark<hotkeys_bookmarks>` hotkeys to mark lines and then
+ press :kbd:`c` to copy to the local system keyboard.
+
+ * Press :kbd:`CTRL` + :kbd:`l` to temporarily switch to "lo-fi"
+ mode where the contents of the current view are printed to the terminal.
+ This option is useful when you are logged into a remote host.
+
+
+Q: How can I force a format for a file?
+---------------------------------------
+
+:Answer: The log format for a file is automatically detected and cannot be
+ forced.
+
+:Solution: Add some of the log file lines to the :ref:`sample<format_sample>`
+ array and then startup lnav to get a detailed explanation of where the format
+ patterns are not matching the sample lines.
+
+:Details: The first lines of the file are matched against the
+ :ref:`regular expressions defined in the format definitions<format_regex>`.
+ The order of the formats is automatically determined so that more specific
+ formats are tried before more generic ones. Therefore, if the expected
+ format is not being chosen for a file, then it means the regular expressions
+ defined by that format are not matching the first few lines of the file.

+Q: Why isn't my log file highlighted correctly?
+-----------------------------------------------
+
+TBD
+
+Q: Why isn't a file being displayed?
+------------------------------------
+
+:Answer: Plaintext files are displayed separately from log files in the TEXT
+ view.
+
+:Solution: Press the :kbd:`t` key to switch to the text view. Or, open the
+ files configuration panel by pressing :kbd:`TAB` to cycle through the
+ panels, and then press :kbd:`/` to search for the file you're interested in.
+ If the file is a log, a new :ref:`log format<log_formats>` will need to be
+ created or an existing one modified.
+
+:Details: If a file being monitored by lnav does not match a known log file
+ format, it is treated as plaintext and will be displayed in the TEXT view.

+
+Log Formats
+===========
+
+Log files loaded into **lnav** are parsed based on formats defined in
+configuration files. Many
+formats are already built in to the **lnav** binary and you can define your own
+using a JSON file. When loading files, each format is checked to see if it can
+parse the first few lines in the file. Once a match is found, that format will
+be considered that files format and used to parse the remaining lines in the
+file. If no match is found, the file is considered to be plain text and can
+be viewed in the "text" view that is accessed with the **t** key.
+
+The following log formats are built into **lnav**:
+
+.. csv-table::
+ :header: "Name", "Table Name", "Description"
+ :widths: 8 5 20
+ :file: format-table.csv
+
+In addition to the above formats, the following self-describing formats are
+supported:
+
+* The
+ `Bro Network Security Monitor <https://www.bro.org/sphinx/script-reference/log-files.html>`_
+ TSV log format is supported in lnav versions v0.8.3+. The Bro log format is
+ self-describing, so **lnav** will read the header to determine the shape of
+ the file.
+* The
+ `W3C Extend Log File Format <https://www.w3.org/TR/WD-logfile.html>`_
+ is supported in lnav versions v0.10.0+. The W3C log format is
+ self-describing, so **lnav** will read the header to determine the shape of
+ the file.
+
+There is also basic support for the `logfmt <https://brandur.org/logfmt>`_
+convention for formatting log messages. Files that use this format must
+have the entire line be key/value pairs and the timestamp contained in a
+field named :code:`time` or :code:`ts`. If the file you're using does not
+quite follow this formatting, but wraps logfmt data with another recognized
+format, you can use the :ref:`logfmt2json` SQL function to convert the data
+into JSON for further analysis.
+
+
+Defining a New Format
+---------------------
+
+New log formats can be defined by placing JSON configuration files in
+subdirectories of the :file:`~/.lnav/formats/` directory. The directories and
+files can be named anything you like, but the files must have the '.json' suffix. A
+sample file containing the builtin configuration will be written to this
+directory when **lnav** starts up. You can consult that file when writing your
+own formats or if you need to modify existing ones. Format directories can
+also contain '.sql' and '.lnav' script files that can be used automate log file
+analysis.
+
+Creating a Format Using Regex101.com (v0.11.0+)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For plain-text log files, the easiest way to create a log format definition is
+to create the regular expression that recognizes log messages using
+https://regex101.com . Simply copy a log line into the test string input box
+on the site and then start editing the regular expression. When building the
+regular expression, you'll want to use named captures for the structured parts
+of the log message. Any raw message text should be matched by a captured named
+"body". Once you have a regex that matches the whole log message, you can use
+**lnav**'s "management CLI" to create a skeleton format file. The skeleton
+will be populated with the regular expression from the site and the test
+string, along with any unit tests, will be added to the "samples" list. The
+"regex101 import" management command is used to create the skeleton and has
+the following form:
+
+.. prompt:: bash
+
+ lnav -m regex101 import <regex101-url> <format-name> [<regex-name>]
+
+If the import was successful, the path to the new format file should be
+printed out. The skeleton will most likely need some changes to make it
+fully functional. For example, the :code:`kind` properties for captured values
+default to :code:`string`, but you'll want to change them to the appropriate
+type.
+
+Format File Reference
+^^^^^^^^^^^^^^^^^^^^^
+
+An **lnav** format file must contain a single JSON object, preferably with a
+:code:`$schema` property that refers to the
+`format-v1.schema <https://lnav.org/schemas/format-v1.schema.json>`_,
+like so:
+
+.. code-block:: json
+
+ {
+ "$schema": "https://lnav.org/schemas/format-v1.schema.json"
+ }
+
+Each format to be defined in the file should be a separate field in the top-level
+object. The field name should be the symbolic name of the format. This value
+will also be used as the SQL table name for the log. The value for each field
+should be another object with the following fields:
+
+ :title: The short and human-readable name for the format.
+ :description: A longer description of the format.
+ :url: A URL to the definition of the format.
+
+ :file-pattern: A regular expression used to match log file paths. Typically,
+ every file format will be tried during the detection process. This field
+ can be used to limit which files a format is applied to in case there is
+ a potential for conflicts.
+
+ .. _format_regex:
+
+ :regex: This object contains sub-objects that describe the message formats
+ to match in a plain-text log file. Each :code:`regex` MUST only match one
+ type of log message. It must not match log messages that are matched by
+ other regexes in this format. This uniqueness requirement is necessary
+ because **lnav** will "lock-on" to a regex and use it to match against
+ the next line in a file. So, if the regexes do not uniquely match each
+ type of log message, messages can be matched by the wrong regex. The
+ "lock-on" behavior is needed to avoid the performance hit of having to
+ try too many different regexes.
+
+ .. note:: Log files that contain JSON messages should not specify this field.
+
+ :pattern: The regular expression that should be used to match log messages.
+ The `PCRE2 <http://www.pcre.org>`_ library is used by **lnav** to do all
+ regular expression matching.
+
+ :module-format: If true, this regex will only be used to parse message
+ bodies for formats that can act as containers, such as syslog. Default:
+ false.
+
+ :json: True if each log line is JSON-encoded.
+
+ :line-format: An array that specifies the text format for JSON-encoded
+ log messages. Log files that are JSON-encoded will have each message
+ converted from the raw JSON encoding into this format. Each element
+ is either an object that defines which fields should be inserted into
+ the final message string and or a string constant that should be
+ inserted. For example, the following configuration will tranform each
+ log message object into a string that contains the timestamp, followed
+ by a space, and then the message body:
+
+ .. code-block:: json
+
+ [ { "field": "ts" }, " ", { "field": "msg" } ]
+
+ :field: The name or `JSON-Pointer <https://tools.ietf.org/html/rfc6901>`_
+ of the message field that should be inserted at this point in the
+ message. The special :code:`__timestamp__` field name can be used to
+ insert a human-readable timestamp. The :code:`__level__` field can be
+ used to insert the level name as defined by lnav.
+
+ .. tip::
+
+ Use a JSON-Pointer to reference nested fields. For example, to include
+ a "procname" property that is nested in a "details" object, you would
+ write the field reference as :code:`/details/procname`.
+
+ :min-width: The minimum width for the field. If the value for the field
+ in a given log message is shorter, padding will be added as needed to
+ meet the minimum-width requirement. (v0.8.2+)
+ :max-width: The maximum width for the field. If the value for the field
+ in a given log message is longer, the overflow algorithm will be applied
+ to try and shorten the field. (v0.8.2+)
+ :align: Specifies the alignment for the field, either "left" or "right".
+ If "left", padding to meet the minimum-width will be added on the right.
+ If "right", padding will be added on the left. (v0.8.2+)
+ :overflow: The algorithm used to shorten a field that is longer than
+ "max-width". The following algorithms are supported:
+
+ :abbrev: Removes all but the first letter in dotted text. For example,
+ "com.example.foo" would be shortened to "c.e.foo".
+ :truncate: Truncates any text past the maximum width.
+ :dot-dot: Cuts out the middle of the text and replaces it with two
+ dots (i.e. '..').
+
+ (v0.8.2+)
+ :timestamp-format: The timestamp format to use when displaying the time
+ for this log message. (v0.8.2+)
+ :default-value: The default value to use if the field could not be found
+ in the current log message. The built-in default is "-".
+ :text-transform: Transform the text in the field. Supported options are:
+ none, uppercase, lowercase, capitalize
+
+ :timestamp-field: The name of the field that contains the log message
+ timestamp. Defaults to "timestamp".
+
+ :timestamp-format: An array of timestamp formats using a subset of the
+ strftime conversion specification. The following conversions are
+ supported: %a, %b, %L, %M, %H, %I, %d, %e, %k, %l, %m, %p, %y, %Y, %S, %s,
+ %Z, %z. In addition, you can also use the following:
+
+ :%L: Milliseconds as a decimal number (range 000 to 999).
+ :%f: Microseconds as a decimal number (range 000000 to 999999).
+ :%N: Nanoseconds as a decimal number (range 000000000 to 999999999).
+ :%q: Seconds from the epoch as a hexidecimal number.
+ :%i: Milliseconds from the epoch.
+ :%6: Microseconds from the epoch.
+
+ :timestamp-divisor: For JSON logs with numeric timestamps, this value is used
+ to divide the timestamp by to get the number of seconds and fractional
+ seconds.
+
+ :subsecond-field: (v0.11.1+) The path to the property in a JSON-lines log
+ message that contains the sub-second time value
+
+ :subsecond-units: (v0.11.1+) The units of the subsecond-field property value.
+ The following values are supported:
+
+ :milli: for milliseconds
+ :micro: for microseconds
+ :nano: for nanoseconds
+
+ :ordered-by-time: (v0.8.3+) Indicates that the order of messages in the file
+ is time-based. Files that are not naturally ordered by time will be sorted
+ in order to display them in the correct order. Note that this sorting can
+ incur a performance penalty when tailing logs.
+
+ :level-field: The name of the regex capture group that contains the log
+ message level. Defaults to "level".
+
+ :body-field: The name of the field that contains the main body of the
+ message. Defaults to "body".
+
+ :opid-field: The name of the field that contains the "operation ID" of the
+ message. An "operation ID" establishes a thread of messages that might
+ correspond to a particular operation/request/transaction. The user can
+ press the 'o' or 'Shift+O' hotkeys to move forward/backward through the
+ list of messages that have the same operation ID. Note: For JSON-encoded
+ logs, the opid field can be a path (e.g. "foo/bar/opid") if the field is
+ nested in an object and it MUST be included in the "line-format" for the
+ 'o' hotkeys to work.
+
+ :module-field: The name of the field that contains the module identifier
+ that distinguishes messages from one log source from another. This field
+ should be used if this message format can act as a container for other
+ types of log messages. For example, an Apache access log can be sent to
+ syslog instead of written to a file. In this case, **lnav** will parse
+ the syslog message and then separately parse the body of the message to
+ determine the "sub" format. This module identifier is used to help
+ **lnav** quickly identify the format to use when parsing message bodies.
+
+ :hide-extra: A boolean for JSON logs that indicates whether fields not
+ present in the line-format should be displayed on their own lines.
+
+ :level: A mapping of error levels to regular expressions. During scanning
+ the contents of the capture group specified by *level-field* will be
+ checked against each of these regexes. Once a match is found, the log
+ message level will set to the corresponding level. The available levels,
+ in order of severity, are: **fatal**, **critical**, **error**,
+ **warning**, **stats**, **info**, **debug**, **debug2-5**, **trace**.
+ For JSON logs with exact numeric levels, the number for the corresponding
+ level can be supplied. If the JSON log format uses numeric ranges instead
+ of exact numbers, you can supply a pattern and the number found in the log
+ will be converted to a string for pattern-matching.
+
+ :multiline: If false, **lnav** will consider any log lines that do not
+ match one of the message patterns to be in error when checking files with
+ the '-C' option. This flag will not affect normal viewing operation.
+ Default: true.
+
+ :value: This object contains the definitions for the values captured by the
+ regexes.
+
+ :kind: The type of data that was captured **string**, **integer**,
+ **float**, **json**, **quoted**.
+ :collate: The name of the SQLite collation function for this value.
+ The standard SQLite collation functions can be used as well as the
+ ones defined by lnav, as described in :ref:`collators`.
+ :identifier: A boolean that indicates whether or not this field represents
+ an identifier and should be syntax colored.
+ :foreign-key: A boolean that indicates that this field is a key and should
+ not be graphed. This should only need to be set for integer fields.
+ :hidden: A boolean for log fields that indicates whether they should
+ be displayed. The behavior is slightly different for JSON logs and text
+ logs. For a JSON log, this property determines whether an extra line
+ will be added with the key/value pair. For text logs, this property
+ controls whether the value should be displayed by default or replaced
+ with an ellipsis.
+ :rewriter: A command to rewrite this field when pretty-printing log
+ messages containing this value. The command must start with ':', ';',
+ or '|' to signify whether it is a regular command, SQL query, or a script
+ to be executed. The other fields in the line are accessible in SQL by
+ using the ':' prefix. The text value of this field will then be replaced
+ with the result of the command when pretty-printing. For example, the
+ HTTP access log format will rewrite the status code field to include the
+ textual version (e.g. 200 (OK)) using the following SQL query:
+
+ .. code-block:: sql
+
+ ;SELECT :sc_status || ' (' || (
+ SELECT message FROM http_status_codes
+ WHERE status = :sc_status) || ') '
+
+ :tags: This object contains the tags that should automatically be added to
+ log messages.
+
+ :pattern: The regular expression evaluated over a line in the log file as
+ it is read in. If there is a match, the log message the line is a part
+ of will have this tag added to it.
+ :paths: This array contains objects that define restrictions on the file
+ paths that the tags will be applied to. The objects in this array can
+ contain:
+
+ :glob: A glob pattern to check against the log files read by lnav.
+
+ .. _format_sample:
+
+ :sample: A list of objects that contain sample log messages. All formats
+ must include at least one sample and it must be matched by one of the
+ included regexes. Each object must contain the following field:
+
+ :line: The sample message.
+ :level: The expected error level. An error will be raised if this level
+ does not match the level parsed by lnav for this sample message.
+
+ :highlights: This object contains the definitions for patterns to be
+ highlighted in a log message. Each entry should have a name and a
+ definition with the following fields:
+
+ :pattern: The regular expression to match in the log message body.
+ :color: The foreground color to use when highlighting the part of the
+ message that matched the pattern. If no color is specified, one will be
+ picked automatically. Colors can be specified using hexadecimal notation
+ by starting with a hash (e.g. #aabbcc) or using a color name as found
+ at http://jonasjacek.github.io/colors/.
+ :background-color: The background color to use when highlighting the part
+ of the message that matched the pattern. If no background color is
+ specified, black will be used. The background color is only considered
+ if a foreground color is specified.
+ :underline: If true, underline the part of the message that matched the
+ pattern.
+ :blink: If true, blink the part of the message that matched the pattern.
+
+Example format:
+
+.. code-block:: json
+
+ {
+ "$schema": "https://lnav.org/schemas/format-v1.schema.json",
+ "example_log" : {
+ "title" : "Example Log Format",
+ "description" : "Log format used in the documentation example.",
+ "url" : "http://example.com/log-format.html",
+ "regex" : {
+ "basic" : {
+ "pattern" : "^(?<timestamp>\\d{4}-\\d{2}-\\d{2}T\\d{2}:\\d{2}:\\d{2}\\.\\d{3}Z)>>(?<level>\\w+)>>(?<component>\\w+)>>(?<body>.*)$"
+ }
+ },
+ "level-field" : "level",
+ "level" : {
+ "error" : "ERROR",
+ "warning" : "WARNING"
+ },
+ "value" : {
+ "component" : {
+ "kind" : "string",
+ "identifier" : true
+ }
+ },
+ "sample" : [
+ {
+ "line" : "2011-04-01T15:14:34.203Z>>ERROR>>core>>Shit's on fire yo!"
+ }
+ ]
+ }
+ }
+
+Patching an Existing Format
+---------------------------
+
+When loading log formats from files, **lnav** will overlay any new data over
+previously loaded data. This feature allows you to override existing value or
+append new ones to the format configurations. For example, you can separately
+add a new regex to the example log format given above by creating another file
+with the following contents:
+
+.. code-block:: json
+
+ {
+ "$schema": "https://lnav.org/schemas/format-v1.schema.json",
+ "example_log" : {
+ "regex" : {
+ "custom1" : {
+ "pattern" : "^(?<timestamp>\\d{4}-\\d{2}-\\d{2}T\\d{2}:\\d{2}:\\d{2}\\.\\d{3}Z)<<(?<level>\\w+)--(?<component>\\w+)>>(?<body>.*)$"
+ }
+ },
+ "sample" : [
+ {
+ "line" : "2011-04-01T15:14:34.203Z<<ERROR--core>>Shit's on fire yo!"
+ }
+ ]
+ }
+ }
+
+.. _scripts:
+
+Scripts
+-------
+
+Format directories may also contain :file:`.sql` and :file:`.lnav` files to help automate
+log file analysis. The SQL files are executed on startup to create any helper
+tables or views and the '.lnav' script files can be executed using the pipe
+hotkey :kbd:`|`. For example, **lnav** includes a "partition-by-boot" script that
+partitions the log view based on boot messages from the Linux kernel. A script
+can have a mix of SQL and **lnav** commands, as well as include other scripts.
+The type of statement to execute is determined by the leading character on a
+line: a semi-colon begins a SQL statement; a colon starts an **lnav** command;
+and a pipe :code:`|` denotes another script to be executed. Lines beginning with a
+hash are treated as comments. The following variables are defined in a script:
+
+.. envvar:: #
+
+ The number of arguments passed to the script.
+
+.. envvar:: __all__
+
+ A string containing all the arguments joined by a single space.
+
+.. envvar:: 0
+
+ The path to the script being executed.
+
+.. envvar:: 1-N
+
+ The arguments passed to the script.
+
+Remember that you need to use the :ref:`:eval<eval>` command when referencing
+variables in most **lnav** commands. Scripts can provide help text to be
+displayed during interactive usage by adding the following tags in a comment
+header:
+
+ :@synopsis: The synopsis should contain the name of the script and any
+ parameters to be passed. For example::
+
+ # @synopsis: hello-world <name1> [<name2> ... <nameN>]
+
+ :@description: A one-line description of what the script does. For example::
+
+ # @description: Say hello to the given names.
+
+
+
+.. tip::
+
+ The :ref:`:eval<eval>` command can be used to do variable substitution for
+ commands that do not natively support it. For example, to substitute the
+ variable, :code:`pattern`, in a :ref:`:filter-out<filter_out>` command:
+
+ .. code-block:: lnav
+
+ :eval :filter-out ${pattern}
+
+VSCode Extension
+^^^^^^^^^^^^^^^^
+
+The `lnav VSCode Extension <https://marketplace.visualstudio.com/items?itemName=lnav.lnav>`_
+can be installed to add syntax highlighting to lnav scripts.
+
+Installing Formats
+------------------
+
+File formats are loaded from subdirectories in :file:`/etc/lnav/formats` and
+:file:`~/.lnav/formats/`. You can manually create these subdirectories and
+copy the format files into there. Or, you can pass the '-i' option to **lnav**
+to automatically install formats from the command-line. For example:
+
+.. code-block:: bash
+
+ $ lnav -i myformat.json
+ info: installed: /home/example/.lnav/formats/installed/myformat_log.json
+
+Format files installed using this method will be placed in the :file:`installed`
+subdirectory and named based on the first format name found in the file.
+
+You can also install formats from git repositories by passing the repository's
+clone URL. A standard set of repositories is maintained at
+(https://github.com/tstack/lnav-config) and can be installed by passing 'extra'
+on the command line, like so:
+
+.. prompt:: bash
+
+ lnav -i extra
+
+These repositories can be updated by running **lnav** with the '-u' flag.
+
+Format files can also be made executable by adding a shebang (#!) line to the
+top of the file, like so::
+
+ #! /usr/bin/env lnav -i
+ {
+ "myformat_log" : ...
+ }
+
+Executing the format file should then install it automatically:
+
+.. code-block:: bash
+
+ $ chmod ugo+rx myformat.json
+ $ ./myformat.json
+ info: installed: /home/example/.lnav/formats/installed/myformat_log.json
+
+.. _format_order:
+
+Format Order When Scanning a File
+---------------------------------
+
+When **lnav** loads a file, it tries each log format against the first 15,000
+lines [#]_ of the file trying to find a match. When a match is found, that log
+format will be locked in and used for the rest of the lines in that file.
+Since there may be overlap between formats, **lnav** performs a test on
+startup to determine which formats match each others sample lines. Using
+this information it will create an ordering of the formats so that the more
+specific formats are tried before the more generic ones. For example, a
+format that matches certain syslog messages will match its own sample lines,
+but not the ones in the syslog samples. On the other hand, the syslog format
+will match its own samples and those in the more specific format. You can
+see the order of the format by enabling debugging and checking the **lnav**
+log file for the "Format order" message:
+
+.. prompt:: bash
+
+ lnav -d /tmp/lnav.log
+
+.. [#] The maximum number of lines to check can be configured. See the
+ :ref:`tuning` section for more details.

+Introduction
+============
+
+The Log File Navigator, **lnav**, is an advanced log file viewer for the
+terminal. It provides an :ref:`easy-to-use interface<ui>` for monitoring and
+analyzing your log files with little to no setup. Simply point **lnav** at
+your log files and it will automatically detect the :ref:`log_formats`, index
+their contents, and display a combined view of all log messages. You can
+navigate through your logs using a variety of :ref:`hotkeys<hotkeys>`.
+:ref:`Commands<commands>` give you additional control over **lnav**'s behavior
+for doing things like applying filters, tagging messages, and more. You can
+then analyze your log messages using the :ref:`sql-ext`.
+
+Dependencies
+------------
+
+When compiling from source, the following dependencies are required:
+
+* `NCurses <http://www.gnu.org/s/ncurses/>`_
+* `PCRE2 <http://www.pcre.org>`_
+* `SQLite <http://www.sqlite.org>`_
+* `ZLib <http://wwww.zlib.net>`_
+* `Bzip2 <http://www.bzip.org>`_
+* `Readline <http://www.gnu.org/s/readline>`_
+* `libcurl <https://curl.haxx.se>`_
+* `libarchive <https://libarchive.org>`_
+
+Installation
+------------
+
+Check the `downloads page <http://lnav.org/downloads>`_ to see if there are
+packages for your operating system. To compile from source, use the following
+commands:
+
+.. prompt:: bash
+
+ ./configure
+ make
+ sudo make install
+
+
+Viewing Logs
+------------
+
+The arguments to **lnav** are the log files, directories, or URLs to be viewed.
+For example, to view all of the CUPS logs on your system:
+
+.. prompt:: bash
+
+ lnav /var/log/cups
+
+The formats of the logs are determined automatically and indexed on-the-fly.
+See :ref:`log_formats` for a listing of the predefined formats and how to
+define your own.
+
+If no arguments are given, **lnav** will try to open the syslog file on your
+system:
+
+.. prompt:: bash
+
+ lnav
+
+
+Setup
+-----
+
+After starting **lnav**, you might want to set the
+:ref:`configuration options<Configuration>` mentioned below. Configuration in
+**lnav** is done using the :code:`:config` command. To change a configuration
+option, start by pressing :kbd:`:` to enter the command prompt. Then,
+type "config" followed by the option name and value.
+
+.. note::
+
+ Tab-completion is available for these configuration options and, in some
+ cases, their values as well.
+
+
+Keymap
+^^^^^^
+
+The keymap defines the mapping from :ref:`hotkeys<hotkeys>` to commands to
+execute. The default mapping is for "U.S." keyboards. The following command
+can be used to change the keymap:
+
+.. code-block:: lnav
+
+ :config /ui/keymap <keymap-name>
+
+The builtin keymaps are:
+
+ :de: `German <https://github.com/tstack/lnav/blob/master/src/keymaps/de-keymap.json>`_
+ :fr: `French <https://github.com/tstack/lnav/blob/master/src/keymaps/fr-keymap.json>`_
+ :sv: `Swedish <https://github.com/tstack/lnav/blob/master/src/keymaps/sv-keymap.json>`_
+ :uk: `United Kingdom <https://github.com/tstack/lnav/blob/master/src/keymaps/uk-keymap.json>`_
+ :us: `United States <https://github.com/tstack/lnav/blob/master/src/keymaps/us-keymap.json>`_
+
+To create or customize a keymap, consult the :ref:`keymaps` section.
+
+
+Theme
+^^^^^
+
+The visual styling of **lnav** can be customized using a theme. The following
+command can be used to the change the theme:
+
+.. code-block:: lnav
+
+ :config /ui/theme <theme-name>
+
+The builtin themes are:
+`default <https://github.com/tstack/lnav/blob/master/src/themes/default-theme.json>`_,
+`eldar <https://github.com/tstack/lnav/blob/master/src/themes/eldar.json>`_,
+`grayscale <https://github.com/tstack/lnav/blob/master/src/themes/grayscale.json>`_,
+`monocai <https://github.com/tstack/lnav/blob/master/src/themes/monocai.json>`_,
+`night-owl <https://github.com/tstack/lnav/blob/master/src/themes/night-owl.json>`_,
+`solarized-dark <https://github.com/tstack/lnav/blob/master/src/themes/solarized-dark.json>`_,
+and
+`solarized-light <https://github.com/tstack/lnav/blob/master/src/themes/default-theme.json>`_.
+
+To create or customize a theme, consult the :ref:`themes` section.
+
+
+Log Formats
+^^^^^^^^^^^
+
+In order for **lnav** to understand your log files, it needs to told how to
+parse the log messages using a log format definition. There are many log
+formats builtin and **lnav** will automatically determine the best format to
+use. In case your log file is not recognized, consult the :ref:`log_formats`
+section for information on how to create a format.

+
+SQLite Interface
+================
+
+Log analysis in **lnav** can be done using the SQLite interface. Log messages
+can be accessed via `virtual tables <https://www.sqlite.org/vtab.html>`_ that
+are created for each file format. The tables have the same name as the log
+format and each message is its own row in the table. For example, given the
+following log message from an Apache access log::
+
+ 127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326
+
+These columns would be available for its row in the :code:`access_log` table:
+
+.. csv-table::
+ :class: query-results
+ :header-rows: 1
+
+ log_line,log_part,log_time,log_idle_msecs,log_level,log_mark,log_comment,log_tags,log_filters,c_ip,cs_method,cs_referer,cs_uri_query,cs_uri_stem,cs_user_agent,cs_username,cs_version,sc_bytes,sc_status
+ 0,<NULL>,2000-10-10 13:55:36.000,0,info,1,<NULL>,<NULL>,<NULL>,127.0.0.1,GET,<NULL>,<NULL>,/apache_pb.gif,<NULL>,frank,HTTP/1.0,2326,200
+
+.. note:: Some columns are hidden by default to reduce the amount of noise in
+ results, but they can still be accessed when explicitly used. The hidden
+ columns are: :code:`log_path`, :code:`log_text`, :code:`log_body`, and
+ :code:`log_raw_text`.
+
+You can activate the SQL prompt by pressing the :kbd:`;` key. At the
+prompt, you can start typing in the desired SQL statement and/or double-tap
+:kbd:`TAB` to activate auto-completion. A help window will appear above
+the prompt to guide you in the usage of SQL keywords and functions.
+
+.. figure:: sql-help.png
+ :align: center
+
+ Screenshot of the online help for the SQL prompt.
+
+.. figure:: group_concat-help.png
+ :align: center
+
+ Screenshot of the online help for the :code:`group_concat()` function.
+
+A simple query to perform on an Apache access log might be to get the average
+and maximum number of bytes returned by the server, grouped by IP address:
+
+.. code-block:: custsqlite
+
+ ;SELECT c_ip, avg(sc_bytes), max(sc_bytes) FROM access_log GROUP BY c_ip
+
+After pressing :kbd:`Enter`, SQLite will execute the query using **lnav**'s
+virtual table implementation to extract the data directly from the log files.
+Once the query has finished, the main window will switch to the DB view to
+show the results. Press :kbd:`q` to return to the log view and press :kbd:`v`
+to return to the log view. If the SQL results contain a
+:code:`log_line` column, you can press to :kbd:`Shift` + :kbd:`V` to
+switch between the DB view and the log
+
+.. figure:: query-results.png
+ :align: center
+
+ Screenshot of the SQL results view.
+
+The DB view has the following display features:
+
+* Column headers stick to the top of the view when scrolling.
+* A stacked bar chart of the numeric column values is displayed underneath the
+ rows. Pressing :kbd:`TAB` will cycle through displaying no columns, each
+ individual column, or all columns.
+* JSON columns in the top row can be pretty-printed by pressing :kbd:`p`.
+ The display will show the value and JSON-Pointer path that can be passed to
+ the `jget`_ function.
+
+
+Log Tables
+----------
+
+Each log format has its own database table that can be used to access log
+messages that match that format. The table name is the same as the format
+name, for example, the :code:`syslog_log` format will have a table that is
+also named :code:`syslog_log`. There is also an :code:`all_logs` table
+that provides access to all messages from all formats.
+
+.. note:: Only the displayed log messages are reflected in the SQLite
+ interface. Any log messages that have been filtered out are not
+ accessible.
+
+The columns in the log tables are made up of several builtins along with
+the values captured by the log format specification. Use the :code:`.schema`
+command in the SQL prompt to examine a dump of the current database schema.
+
+The following columns are builtin and included in a :code:`SELECT *`:
+
+ :log_line: The line number for the message in the log view.
+ :log_part: The partition the message is in. This column can be changed by
+ an :code:`UPDATE` or the :ref:`:parition-name<partition_name>` command.
+ :log_time: The adjusted timestamp for the log message. This time can differ
+ from the log message's time stamp if it arrived out-of-order and the log
+ format expects log files to be time-ordered.
+ :log_actual_time: The log messages original timestamp in the file.
+ :log_idle_msecs: The difference in time between this messages and the
+ previous. The unit of time is milliseconds.
+ :log_level: The log message level.
+ :log_mark: True if the log message was marked by the user.
+ :log_comment: The comment for the message. This column can be changed by
+ an :code:`UPDATE` or the :ref:`:comment<comment>` command.
+ :log_tags: A JSON list of tags for the message. This column can be changed
+ by an :code:`UPDATE` or the :ref:`:tag<tag>` command.
+ :log_filters: A JSON list of filter IDs that matched this message
+
+The following columns are builtin and are hidden, so they will *not* be
+included in a :code:`SELECT *`:
+
+ :log_time_msecs: The adjusted timestamp for the log message as the number of
+ milliseconds from the epoch. This column can be more efficient to use for
+ time-related operations, like :ref:`timeslice()<timeslice>`.
+ :log_path: The path to the log file this message is from.
+ :log_text: The full text of the log message.
+ :log_body: The body of the log message.
+ :log_raw_text: The raw text of this message from the log file. In this case
+ of JSON and CSV logs, this will be the exact line of JSON-Line and CSV
+ text from the file.
+
+Extensions
+----------
+
+To make it easier to analyze log data from within **lnav**, there are several
+built-in extensions that provide extra functions and collators beyond those
+`provided by SQLite <http://www.sqlite.org/lang_corefunc.html>`_. The majority
+of the functions are from the
+`extensions-functions.c <http://www.sqlite.org/contrib>`_ file available from
+the `sqlite.org <http://sqlite.org>`_ web site.
+
+.. tip:: You can include a SQLite database file on the command-line and use
+ **lnav**'s interface to perform queries. The database will be attached with
+ a name based on the database file name.
+
+Commands
+--------
+
+A SQL command is an internal macro implemented by lnav.
+
+* .schema - Open the schema view. This view contains a dump of the schema
+ for the internal tables and any tables in attached databases.
+* .msgformats - Executes a canned query that groups and counts log messages by
+ the format of their message bodies. This command can be useful for quickly
+ finding out the types of messages that are most common in a log file.
+
+Variables
+---------
+
+The following variables are available in SQL statements:
+
+* $LINES - The number of lines in the terminal window.
+* $COLS - The number of columns in the terminal window.
+
+Environment
+-----------
+
+Environment variables can be accessed in queries using the usual syntax of
+:code:`$VAR_NAME`. For example, to read the value of the "USER" variable, you

+
+SQLite Tables Reference
+=======================
+
+In addition to the tables generated for each log format, **lnav** includes
+the following tables/views:
+
+* `environ`_
+* `lnav_events`_
+* `lnav_file`_
+* `lnav_user_notifications`_
+* `lnav_views`_
+* `lnav_views_echo`_
+* `lnav_view_stack`_
+* `lnav_view_filters`_
+* `lnav_view_filter_stats`_
+* `lnav_view_filters_and_stats`_
+* `all_logs`_
+* `http_status_codes`_
+* `regexp_capture(<string>, <regex>)`_
+
+These extra tables provide useful information and can let you manipulate
+**lnav**'s internal state. You can get a dump of the entire database schema
+by executing the '.schema' SQL command, like so::
+
+ ;.schema
+
+environ
+-------
+
+The **environ** table gives you access to the **lnav** process' environment
+variables. You can SELECT, INSERT, and UPDATE environment variables, like
+so:
+
+.. code-block:: custsqlite
+
+ ;SELECT * FROM environ WHERE name = 'SHELL'
+ name value
+ SHELL /bin/tcsh
+
+ ;UPDATE environ SET value = '/bin/sh' WHERE name = 'SHELL'
+
+Environment variables can be used to store simple values or pass values
+from **lnav**'s SQL environment to **lnav**'s commands. For example, the
+"open" command will do variable substitution, so you can insert a variable
+named "FILENAME" and then open it in **lnav** by referencing it with
+"$FILENAME":
+
+.. code-block:: custsqlite
+
+ ;INSERT INTO environ VALUES ('FILENAME', '/path/to/file')
+ :open $FILENAME
+
+
+.. _table_lnav_events:
+
+lnav_events
+-----------
+
+The **lnav_events** table allows you to react to events that occur while
+**lnav** is running using SQLite triggers. For example, when a file is
+opened, a row is inserted into the :code:`lnav_events` table that contains
+a timestamp and a JSON object with the event ID and the path of the file.
+The following columns are available in this table:
+
+ :ts: The timestamp of the event.
+ :content: A JSON object that contains the event information. See the
+ :ref:`event_reference` for more information about the types
+ of events that are available.
+
+lnav_file
+---------
+
+The **lnav_file** table allows you to examine and perform limited updates to
+the metadata for the files that are currently loaded into **lnav**. The
+following columns are available in this table:
+
+ :device: The device the file is stored on.
+ :inode: The inode for the file on the device.
+ :filepath: If this is a real file, it will be the absolute path. Otherwise,
+ it is a symbolic name. If it is a symbolic name, it can be UPDATEd so that
+ this file will be considered when saving and loading session information.
+ :format: The log file format for the file.
+ :lines: The number of lines in the file.
+ :time_offset: The millisecond offset for timestamps. This column can be
+ UPDATEd to change the offset of timestamps in the file.
+
+.. _table_lnav_user_notifications:
+
+lnav_user_notifications
+-----------------------
+
+The :code:`lnav_user_notifications` table allows you to display a custom message
+in the top-right corner of the UI. For example, to display "Hello, World!",
+you can enter:
+
+.. code-block:: custsqlite
+
+ ;REPLACE INTO lnav_user_notifications (message) VALUES ('Hello, World!')
+
+There are additional columns to have finer control of what is displayed and
+when:
+
+ :id: The unique ID for the message, defaults to "org.lnav.user". This is
+ the primary key for the table, so more than one type of message is not
+ allowed.
+ :priority: The priority of the message. Higher priority messages will be
+ displayed until they are cleared or are expired.
+ :created: The time the message was created.
+ :expiration: The time when the message should expire or NULL if it should
+ not automatically expire.
+ :views: A JSON array of view names where the message is applicable or NULL
+ if the message should be shown in all views.
+ :message: The message itself.
+
+This table will most likely be used in combination with :ref:`Events` and the
+`lnav_views_echo`_ table.
+
+lnav_views
+----------
+
+The **lnav_views** table allows you to SELECT and UPDATE information related
+to **lnav**'s "views" (e.g. log, text, ...). The following columns are
+available in this table:
+
+ :name: The name of the view.
+ :top: The line number at the top of the view. This value can be UPDATEd to
+ move the view to the given line.
+ :left: The left-most column number to display. This value can be UPDATEd to
+ move the view left or right.
+ :height: The number of lines that are displayed on the screen.
+ :inner_height: The number of lines of content being displayed.
+ :top_time: The timestamp of the top line in the view or NULL if the view is
+ not time-based. This value can be UPDATEd to move the view to the given
+ time.
+ :paused: Indicates if the view is paused and will not load new data.
+ :search: The search string for this view. This value can be UPDATEd to
+ initiate a text search in this view.
+
+lnav_views_echo
+---------------
+
+The :code:`lnav_views_echo` table is a real SQLite table that you can create
+TRIGGERs on in order to react to users moving around in a view.
+
+.. note::
+
+ The table is periodically updated to reflect the current state of the views.
+ The changes are *not* performed immediately after the user action.
+
+lnav_view_stack
+---------------
+
+The **lnav_view_stack** table allows you to SELECT and DELETE from the stack of
+**lnav** "views" (e.g. log, text, ...). The following columns are available in
+this table:
+
+ :name: The name of the view.
+
+.. _table_lnav_view_filters:
+
+lnav_view_filters
+-----------------
+
+The **lnav_view_filters** table allows you to manipulate the filters in the
+**lnav** views. The following columns are available in this table:
+
+ :view_name: The name of the view the filter is applied to.
+ :filter_id: The filter identifier. This will be assigned on insertion.
+ :enabled: Indicates whether this filter is enabled or disabled.
+ :type: The type of filter, either 'in' or 'out'.
+ :pattern: The regular expression to filter on.
+
+This table supports SELECT, INSERT, UPDATE, and DELETE on the table rows to
+read, create, update, and delete filters for the views.
+
+lnav_view_filter_stats
+----------------------
+
+The **lnav_view_filter_stats** table allows you to get information about how
+many lines matched a given filter. The following columns are available in
+this table:
+
+ :view_name: The name of the view.
+ :filter_id: The filter identifier.
+ :hits: The number of lines that matched this filter.
+
+This table is read-only.
+
+lnav_view_filters_and_stats
+---------------------------
+
+The **lnav_view_filters_and_stats** view joins the **lnav_view_filters** table
+with the **lnav_view_filter_stats** table into a single view for ease of use.
+
+all_logs
+--------
+
+.. f0:sql.tables.all_logs
+
+The **all_logs** table lets you query the format derived from the **lnav**
+log message parser that is used to automatically extract data, see
+:ref:`data-ext` for more details.
+
+http_status_codes
+-----------------
+
+The **http_status_codes** table is a handy reference that can be used to turn
+HTTP status codes into human-readable messages.
+
+regexp_capture(<string>, <regex>)
+---------------------------------
+
+The **regexp_capture()** table-valued function applies the regular expression
+to the given string and returns detailed results for the captured portions of
+the string.

+
+User Interface
+==============
+
+The **lnav** TUI displays the content of the current "view" in the middle,
+with status bars above and below, and the interactive prompt as the last line.
+
+.. figure:: lnav-ui.png
+ :align: center
+ :alt: Screenshot of lnav showing a mix of syslog and web access_log messages.
+
+ Screenshot of **lnav** viewing syslog and web access_log messages.
+
+The default view shows the log messages from the log files that have been
+loaded. There are other views for displaying content like plaintext files
+and SQL results. The :ref:`ui_views` section describes the characteristics of
+each view in more detail. You can switch to the different views using the
+hotkeys described in the :ref:`hotkeys_display` section or by pressing
+:kbd:`ENTER` to activate the breadcrumb bar, moving to the first crumb, and
+then selecting the desired view. You can switch back to the previous view by
+pressing :kbd:`q`. You can switch forward to the new view by pressing
+:kbd:`a`. If the views are time-based (e.g. log and histogram), pressing
+:kbd:`Shift` + :kbd:`q` and :kbd:`Shift` + :kbd:`a` will synchronize the top
+times in the views.
+
+The right side of the display has a proportionally sized 'scrollbar' that
+shows:
+
+* the current position in the file;
+* the locations of errors/warnings in the log files by using red or yellow
+ coloring;
+* the locations of search hits by using a tick-mark pointing to the left;
+* the locations of bookmarks by using a tick-mark pointing to the right.
+
+Top Status Bar
+--------------
+
+The top status bar shows the current time and messages stored in the
+:ref:`table_lnav_user_notifications` table.
+
+Below the top status bar is the breadcrumb bar that displays the semantic
+location of the top line in the main view. For example, within a
+pretty-printed JSON document, it will show the path to property at the top
+of the view. The actual content of the bar depends on the current view and
+will be updated as you navigate around the main view. The bar can also be
+used to navigate around the document by focusing on it.
+
+Breadcrumb Bar
+--------------
+
+.. figure:: lnav-breadcrumbs-help.png
+ :align: center
+ :figwidth: 90%
+
+ Screenshot of the breadcrumb bar focused and navigating the help text
+
+To focus on the breadcrumb bar, press :kbd:`ENTER`. The :kbd:`←`/:kbd:`→`
+cursor keys can be used to select a crumb and the :kbd:`↑`/:kbd:`↓` keys can
+be used select a value of that crumb. To accept a value and drop focus on the
+bar, press :kbd:`ENTER`. To accept a value and move to the next crumb, press
+:kbd:`→`. Using :kbd:`→` makes it quicker to drill down into a document
+without having to constantly switch focus. To drop focus on the bar without
+accepting anything, press :kbd:`Escape`.
+
+There are three types of crumbs:
+
+* a dropdown where one of a limited set of values can be selected;
+* a combobox where a value can be entered directly or selected;
+* a numeric input for entering array indexes.
+
+When a dropdown or combobox is selected, you can type part of the desired value
+to filter the list of values. For example, the first crumb is always the
+current view, typing in "hi" will filter the list down to the "HIST" value.
+
+Configuration Panels
+--------------------
+
+.. figure:: lnav-config-header.png
+ :align: center
+ :figwidth: 90%
+
+ Screenshot of the header for the configuration panels when they are hidden.
+
+After the main view content, there is a header bar for two configuration
+panels: Files and Filters. These panels provide visual access to parts of
+lnav's configuration. To access the panels, press the :kbd:`TAB` key.
+To hide the panels again, press :kbd:`q`.
+
+.. figure:: lnav-files-panel.png
+ :align: center
+ :figwidth: 90%
+
+ Screenshot of the files panel showing the loaded files.
+
+The Files panel is open initially to display progress in loading files.
+The following information can be displayed for each file:
+
+* the "unique" portion of the path relative to the other files;
+* the amount of data that has been indexed;
+* the date range of log messages contained in the file;
+* the errors that were encountered while trying to index the file;
+* the notes recorded for files where some automatic action was taken,
+ like hiding the file if it was seen as a duplicate of another file.
+
+.. figure:: lnav-filters-panel.png
+ :align: center
+ :figwidth: 90%
+
+ Screenshot of the filters panel showing an OUT and a disabled IN filter.
+
+If the view supports filtering, there will be a status line showing the
+following:
+
+* the number of enabled filters and the total number of filters;
+* the number of lines that are **not** displayed because of filtering.
+
+To edit the filters, you can press TAB to change the focus from the main
+view to the filter editor. The editor allows you to create, enable/disable,
+and delete filters easily.
+
+Bottom Status Bar
+-----------------
+
+The second to last line is the bottom status bar, which shows the following:
+
+* the line number of the top line, starting from zero;
+* the location within the view, as a percentage;
+* the current search hit, the total number of hits, and the search term;
+* the loading indicator.
+
+When the interactive prompt is active, this bar can show the prompt
+description, help text, or error message.
+
+Prompt
+------
+
+Finally, the last line on the display is where you can enter search
+patterns and execute internal commands, such as converting a
+unix-timestamp into a human-readable date. The following key-presses
+will activate a corresponding prompt:
+
+* :kbd:`/` - The search prompt. You can enter a PCRE2-flavored regular
+ expression to search for in the current view.
+* :kbd:`:` - The command prompt. Commands are used to perform common
+ operations.
+* :kbd:`;` - The SQL prompt. SQL queries can be used for log analysis
+ and manipulating **lnav**'s state.
+* :kbd:`|` - The script prompt. Enter a path to the lnav script to
+ execute, along with the arguments to pass in.
+
+The command-line is by the readline library, so the usual set of keyboard
+shortcuts can be used for editing and moving within the command-line.
+
+.. _ui_views:
+
+Views
+-----
+
+The accessible content within lnav is separated into the following views.
+
+LOG
+^^^
+
+The log view displays the log messages from any loaded log files in time
+order. This view will be shown by default if any log messages are available.
+
+On color displays, the log messages will be highlighted as follows:
+
+* Errors will be colored in red;
+* warnings will be yellow;
+* search hits are reverse video;
+* various color highlights will be applied to: IP addresses, SQL keywords,
+ XML tags, file and line numbers in Java backtraces, and quoted strings;
+* "identifiers" in the messages will be randomly assigned colors based on their
+ content (works best on "xterm-256color" terminals).
+
+.. note::
+
+ If the coloring is too much for your tastes, you can change to the
+ "grayscale" theme by entering the following command:
+
+ .. code-block:: lnav
+
+ :config /ui/theme grayscale
+
+.. note::
+
+ If a log message has a timestamp that is out-of-order with its neighboring
+ messages, the timestamp will be highlighted in yellow. When one of these
+ messages is at the top of the log view, an overlay will display the
+ difference between the "actual time" and the "received time". The "actual
+ time" is the original textual timestamp. The "received time" is the time
+ of an earlier message that is larger than this log message's time.
+
+The breadcrumb bar will show the following crumbs:
+
+* the timestamp for the top line;
+* the log format for the top line;
+* the name of the file the top line was pulled from;
+* the "operation ID" of the top log message, if it is supported by the log
+ format.
+
+These crumbs are interactive and can be used to navigate to different parts
+of the log view. For example, selecting a different value in the log format
+crumb will jump to the first message with that format.
+
+TEXT
+^^^^
+
+The text view displays files for which lnav could not detect any log messages.
+
+Markdown
+""""""""
+
+Files with an :code:`.md` (or :code:`.markdown`) extension will be treated as
+Markdown files and rendered separately.
+
+DB
+^^
+
+The DB view shows the results of queries done through the SQLite interface.
+You can execute a query by pressing :kbd:`;` and then entering a SQL statement.
+You can switch to the SQL view by pressing :kbd:`v`.
+
+HELP
+^^^^
+
+The help view displays the builtin help text. Press :kbd:`?` to switch to the
+help view at any time. While in the help view, the breadcrumb bar can be used
+to navigate to different sections of the document.
+
+HIST
+^^^^
+
+The histogram view displays a stacked bar chart of messages over time
+classified by their log level and whether they've been bookmarked. Press
+:kbd:`i` to switch back and forth to the histogram view. You can also press
+:kbd:`Shift`+:kbd:`i` to toggle the histogram view while synchronizing the top
+time. While in the histogram view, pressing :kbd:`z`/:kbd:`Shift`+:kbd:`z`
+will zoom in/out.
+
+PRETTY
+^^^^^^
+
+The pretty-print view takes the text displayed in the current view and shows
+the result of a pretty-printer run on that text. For example, if a log
+message contained an XML message on a single line, the pretty-printer would
+break the XML across multiple lines with appropriate indentation.
+
+SCHEMA
+^^^^^^
+
+The schema view displays the current schema of the builtin SQLite database.
+
+SPECTRO
+^^^^^^^
+
+The spectrogram view is a "three"-dimensional display of data points of a log
+field or a SQL query column. The dimensions are time on the Y axis, the range
+of data point values on the X axis, and the number of data points as a color.
+For example, if you were to visualize process CPU usage over time, the range
+of values on the X axis would be CPU percentages and there would be colored
+blocks at each point on the line where a process had that CPU percentage, like
+so
+
+.. figure:: lnav-spectro-cpu-pct.png
+ :align: center
+
+ Screenshot of the **lnav** spectrogram view showing CPU usage of processes.
+
+The colors correspond to the relative number of data points in a bucket.
+The legend overlaid at the top line in the view shows the counts of data
+points that are in a particular color, with green having the fewest number of
+data points, yellow the middle, and red the most. You can select a particular
+bucket using the cursor keys to see the exact number of data points and the
+range of values. The panel at the bottom of the view shows the data points
+themselves from the original source, the log file or the SQL query results.
+You can press :kbd:`TAB` to focus on the details panel so you can scroll
+around and get a closer look at the values.

+
+Usage
+=====
+
+This chapter contains an overview of how to use **lnav**.
+
+
+Basic Controls
+--------------
+
+Like most file viewers, scrolling through files can be done with the usual
+:ref:`hotkeys<hotkeys>`. For non-trivial operations, you can enter the
+:ref:`command<commands>` prompt by pressing :kbd:`:`. To analyze data in a
+log file, you can enter the :ref:`SQL prompt<sql-ext>` by pressing :kbd:`;`.
+
+.. tip::
+
+ Check the bottom right corner of the screen for tips on hotkeys that might
+ be useful in the current context.
+
+ .. figure:: hotkey-tips.png
+ :align: center
+
+ When **lnav** is first open, it suggests using :kbd:`e` and
+ :kbd:`Shift` + :kbd:`e` to jump to error messages.
+
+
+Viewing Files
+-------------
+
+The files to view in **lnav** can be given on the command-line or passed to the
+:ref:`:open<open>` command. A
+`glob pattern <https://en.wikipedia.org/wiki/Glob_(programming)>`_ can be given
+to watch for files with a common name. If the path is a directory, all of the
+files in the directory will be opened and the directory will be monitored for
+files to be added or removed from the view. If the path is an archive or
+compressed file (and lnav was built with libarchive), the archive will be
+extracted to a temporary location and the files within will be loaded. The
+files that are found will be scanned to identify their file format. Files
+that match a log format will be collated by time and displayed in the LOG
+view. Plain text files can be viewed in the TEXT view, which can be accessed
+by pressing :kbd:`t`.
+
+
+Archive Support
+^^^^^^^^^^^^^^^
+
+.. f0:archive
+
+If **lnav** is compiled with `libarchive <https://www.libarchive.org>`_,
+any files to be opened will be examined to see if they are a supported archive
+type. If so, the contents of the archive will be extracted to the
+:code:`$TMPDIR/lnav-user-${UID}-work/archives/` directory. Once extracted, the
+files within will be loaded into lnav. To speed up opening large amounts of
+files, any file that meets the following conditions will be automatically
+hidden and not indexed:
+
+* Binary files
+* Plain text files that are larger than 128KB
+* Duplicate log files
+
+The unpacked files will be left in the temporary directory after exiting
+**lnav** so that opening the same archive again will be faster. Unpacked
+archives that have not been accessed in the past two days will be automatically
+deleted the next time **lnav** is started.
+
+
+.. _remote:
+
+Remote Files
+^^^^^^^^^^^^
+
+Files on remote machines can be viewed and tailed if you have access to the
+machines via SSH. First, make sure you can SSH into the remote machine without
+any interaction by: 1) accepting the host key as known and 2) copying your
+identity's public key to the :file:`.ssh/authorized_keys` file on the remote
+machine. Once the setup is complete, you can open a file on a remote host
+using the same syntax as :command:`scp(1)` where the username and host are
+given, followed by a colon, and then the path to the files, like so::
+
+ [user@]host:/path/to/logs
+
+For example, to open :file:`/var/log/syslog.log` on "host1.example.com" as the
+user "dean", you would write:
+
+.. prompt:: bash
+
+ lnav dean@host1.example.com:/var/log/syslog.log
+
+Remote files can also be opened using the :ref:`:open<open>` command. Opening
+a remote file in the TUI has the advantage that the file path can be
+:kbd:`TAB`-completed and a preview is shown of the first few lines of the
+file.
+
+.. note::
+
+ If lnav is installed from the `snap <https://snapcraft.io/lnav>`_, you will
+ need to connect it to the
+ `ssh-keys plug <https://snapcraft.io/docs/ssh-keys-interface>`_ using the
+ following command:
+
+ .. prompt:: bash
+
+ sudo snap connect lnav:ssh-keys
+
+.. note::
+
+ Remote file access is implemented by transferring an
+ `αcτµαlly pδrταblε εxεcµταblε <https://justine.lol/ape.html>`_ to the
+ destination and invoking it. An APE binary can run on most any x86_64
+ machine and OS (i.e. MacOS, Linux, FreeBSD, Windows). The binary is
+ baked into the lnav executable itself, so there is no extra setup that
+ needs to be done on the remote machine.
+
+ The binary file is named ``tailer.bin.XXXXXX`` where *XXXXXX* is 6 random digits.
+ The file is, under normal circumstancies, deleted immediately.
+
+Searching
+---------
+
+Any log messages that are loaded into **lnav** are indexed by time and log
+level (e.g. error, warning) to make searching quick and easy with
+:ref:`hotkeys<hotkeys>`. For example, pressing :kbd:`e` will jump to the
+next error in the file and pressing :kbd:`Shift` + :kbd:`e` will jump to
+the previous error. Plain text searches can be done by pressing :kbd:`/`
+to enter the search prompt. A regular expression can be entered into the
+prompt to start a search through the current view.
+
+
+.. _filtering:
+
+Filtering
+---------
+
+To reduce the amount of noise in a log file, **lnav** can hide log messages
+that match certain criteria. The following sub-sections explain ways to go
+about that.
+
+
+Regular Expression Match
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+If there are log messages that you are not interested in, you can do a
+"filter out" to hide messages that match a pattern. A filter can be created
+using the interactive editor, the :ref:`:filter-out<filter_out>` command, or
+by doing an :code:`INSERT` into the
+:ref:`lnav_view_filters<table_lnav_view_filters>` table.
+
+If there are log messages that you are only interested in, you can do a
+"filter in" to only show messages that match a pattern. The filter can be
+created using the interactive editor, the :ref:`:filter-in<filter_in>` command,
+or by doing an :code:`INSERT` into the
+:ref:`lnav_view_filters<table_lnav_view_filters>` table.
+
+
+SQLite Expression
+^^^^^^^^^^^^^^^^^
+
+Complex filtering can be done by passing a SQLite expression to the
+:ref:`:filter-expr<filter_expr>` command. The expression will be executed for
+every log message and if it returns true, the line will be shown in the log
+view.
+
+
+Time
+^^^^
+
+To limit log messages to a given time frame, the
+:ref:`:hide-lines-before<hide_lines_before>` and
+:ref:`:hide-lines-after<hide_lines_after>` commands can be used to specify
+the beginning and end of the time frame.
+
+
+Log level
+^^^^^^^^^
+
+To hide messages below a certain log level, you can use the
+:ref:`:set-min-log-level<set_min_log_level>` command.
+
+.. _search_tables:
+
+Search Tables
+-------------
+
+Search tables allow you to access arbitrary data in log messages through
+SQLite virtual tables. If there is some data in a log message that you can
+match with a regular expression, you can create a search-table that matches
+that data and any capture groups will be plumbed through as columns in the
+search table.
+
+Creating a search table can be done interactively using the
+:ref:`:create-search-table<create_search_table>` command or by adding it to
+a :ref:`log format definition<log_formats>`. The main difference between
+the two is that tables defined as part of a format will only search messages
+from log files with that format and the tables will include log message
+columns defined in that format. Whereas a table created with the command
+will search messages from all different formats and no format-specific
+columns will be included in the table.
+
+.. _taking_notes:
+
+Taking Notes
+------------
+
+A few of the columns in the log tables can be updated on a row-by-row basis to
+allow you to take notes. The majority of the columns in a log table are
+read-only since they are backed by the log files themselves. However, the
+following columns can be changed by an :code:`UPDATE` statement:
+
+* **log_part** - The "partition" the log message belongs to. This column can
+ also be changed by the :ref:`:partition-name<partition_name>` command.
+* **log_mark** - Indicates whether the line has been bookmarked.
+* **log_comment** - A free-form text field for storing commentary. This
+ column can also be changed by the :ref:`:comment<comment>` command.
+* **log_tags** - A JSON list of tags associated with the log message. This
+ column can also be changed by the :ref:`:tag<tag>` command.
+
+While these columns can be updated by through other means, using the SQL
+interface allows you to make changes automatically and en masse. For example,
+to bookmark all lines that have the text "something interesting" in the log
+message body, you can execute:
+
+.. code-block:: custsqlite
+
+ ;UPDATE all_logs SET log_mark = 1 WHERE log_body LIKE '%something interesting%'
+
+As a more advanced example of the power afforded by SQL and **lnav**'s virtual
+tables, we will tag log messages where the IP address bound by dhclient has
+changed. For example, if dhclient reports "bound to 10.0.0.1" initially and
+then reports "bound to 10.0.0.2", we want to tag only the messages where the
+IP address was different from the previous message. While this can be done
+with a single SQL statement [#]_, we will break things down into a few steps for
+this example. First, we will use the :ref:`:create-search-table<create_search_table>`
+command to match the dhclient message and extract the IP address:
+
+.. code-block:: lnav
+
+ :create-search-table dhclient_ip bound to (?<ip>[^ ]+)
+
+The above command will create a new table named :code:`dhclient_ip` with the
+standard log columns and an :code:`ip` column that contains the IP address.
+Next, we will create a view over the :code:`dhclient_ip` table that returns
+the log message line number, the IP address from the current row and the IP
+address from the previous row:
+
+.. code-block:: custsqlite
+
+ ;CREATE VIEW IF NOT EXISTS dhclient_ip_changes AS SELECT log_line, ip, lag(ip) OVER (ORDER BY log_line) AS prev_ip FROM dhclient_ip
+
+Finally, the following :code:`UPDATE` statement will concatenate the tag
+"#ipchanged" onto the :code:`log_tags` column for any rows in the view where
+the current IP is different from the previous IP:
+
+.. code-block:: custsqlite
+
+ ;UPDATE syslog_log SET log_tags = json_concat(log_tags, '#ipchanged') WHERE log_line IN (SELECT log_line FROM dhclient_ip_changes WHERE ip != prev_ip)
+
+Since the above can be a lot to type out interactively, you can put these
+commands into a :ref:`script<scripts>` and execute that script with the
+:kbd:`\|` hotkey.
+
+.. [#] The expression :code:`regexp_match('bound to ([^ ]+)', log_body) as ip`
+ can be used to extract the IP address from the log message body.
+
+Sharing Sessions With Others
+----------------------------
+
+After setting up filters, bookmarks, and making notes, you might want to share
+your work with others. If they have access to the same log files, you can
+use the :ref:`:export-session-to<export_session_to>` command to write an
+executable **lnav** script that will recreate the current session state. The
+script contains various SQL statements and **lnav** commands that capture the
+current state. So, you should feel free to modify the script or use it as a
+reference to learn about more advanced uses of lnav.
+
+The script will capture the file paths that were explicitly specified and
+not the files that were actually opened. For example, if you specified
+"/var/log" on the command line, the script will include
+:code:`:open /var/log/*` and not an individual open for each file in that
+directory.
+
+Also, in order to support archives of log files, lnav will try to find the
+directory where the archive was unpacked and use that as the base for the
+:code:`:open` command. Currently, this is done by searching for the top
+"README" file in the directory hierarchy containing the files [1]_. The
+consumer of the session script can then set the :code:`LOG_DIR_0` (or 1, 2,
+...) environment variable to change where the log files will be loaded from.
+
+.. [1] It is assumed a log archive would have a descriptive README file.
+ Other heuristics may be added in the future.

+An h1 header
+============
+
+Paragraphs are separated by a blank line.
+
+2nd paragraph. *Italic*, **bold**, and `monospace`. Itemized lists
+look like:
+
+ * this one
+ * that one
+ * the other one
+
+Note that --- not considering the asterisk --- the actual text
+content starts at 4-columns in.
+
+> Block quotes are
+> written like so.
+>
+> They can span multiple paragraphs,
+> if you like.
+
+Use 3 dashes for an em-dash. Use 2 dashes for ranges (ex., "it's all
+in chapters 12--14"). Three dots ... will be converted to an ellipsis.
+Unicode is supported. ☺
+
+
+
+An h2 header
+------------
+
+Here's a numbered list:
+
+ 1. first item
+ 2. second item
+ 3. third item
+
+Note again how the actual text starts at 4 columns in (4 characters
+from the left side). Here's a code sample:
+
+ # Let me re-iterate ...
+ for i in 1 .. 10 { do-something(i) }
+
+As you probably guessed, indented 4 spaces. By the way, instead of
+indenting the block, you can use delimited blocks, if you like:
+
+~~~
+define foobar() {
+ print "Welcome to flavor country!";
+}
+~~~
+
+(which makes copying & pasting easier). You can optionally mark the
+delimited block for Pandoc to syntax highlight it:
+
+~~~python
+import time
+# Quick, count to ten!
+for i in range(10):
+ # (but not *too* quick)
+ time.sleep(0.5)
+ print i
+~~~
+
+
+
+### An h3 header ###
+
+Now a nested list:
+
+ 1. First, get these ingredients:
+
+ * carrots
+ * celery
+ * lentils
+
+ 2. Boil some water.
+
+ 3. Dump everything in the pot and follow
+ this algorithm:
+
+ find wooden spoon
+ uncover pot
+ stir
+ cover pot
+ balance wooden spoon precariously on pot handle
+ wait 10 minutes
+ goto first step (or shut off burner when done)
+
+ Do not bump wooden spoon or it will fall.
+
+Notice again how text always lines up on 4-space indents (including
+that last line which continues item 3 above).
+
+Here's a link to [a website](https://lnav.org), to a [local
+doc](../index.md), and to a [section heading in the current
+doc](#an-h2-header). Here's a footnote [^1].
+
+[^1]: Footnote text goes here.
+
+Tables can look like this:
+
+size material color
+---- ------------ ------------
+9 leather brown
+10 hemp canvas natural
+11 glass transparent
+
+Table: Shoes, their sizes, and what they're made of
+
+(The above is the caption for the table.) Pandoc also supports
+multi-line tables:
+
+-------- -----------------------
+keyword text
+-------- -----------------------
+red Sunsets, apples, and
+ other red or reddish
+ things.
+
+green Leaves, grass, frogs
+ and other things it's
+ not easy being.
+-------- -----------------------
+
+A horizontal rule follows.
+
+***
+
+Here's a definition list:
+
+apples
+ : Good for making applesauce.
+oranges
+ : Citrus!
+tomatoes
+ : There's no "e" in tomatoe.
+
+Again, text is indented 4 spaces. (Put a blank line between each
+term/definition pair to spread things out more.)
+
+Here's a "line block":
+
+| Line one
+| Line too
+| Line tree
+
+and images can be specified like so:
+
+![example image](../../../assets/images/lnav-front-page.png "An exemplary image")
+
+Inline math equations go in like so: $\omega = d\phi / dt$. Display
+math should get its own line and be put in in double-dollarsigns:
+
+$$I = \int \rho R^{2} dV$$
+
+And note that you can backslash-escape any punctuation characters
+which you wish to be displayed literally, ex.: \`foo\`, \*bar\*, etc. \ No newline at end of file

+# Tutorial 1
+
+Welcome to the first _interactive_ **lnav** tutorial!
+
+This tutorial will guide you through the basics of navigating log files.
+Pressing `q` will display an example log file to try out commands on.
+Pressing `y` will return you to the next step in the tutorial.
+
+## Step 1
+
+Finding errors quickly is one of the main use-cases for **lnav**. To
+make that quick and easy, **lnav** parses the log messages in log files
+as they are loaded and builds indexes of the errors and warnings. You
+can then use the following hotkeys to jump to them in the log view:
+
+| Key | Action |
+|-----------|----------------------------------------------------------------------------------|
+| `e` | Move to the next <span class="-lnav_log-level-styles_error">error</span> |
+| `Shift+E` | Move to the previous <span class="-lnav_log-level-styles_error">error</span> |
+| `w` | Move to the next <span class="-lnav_log-level-styles_warning">warning</span> |
+| `Shift+W` | Move to the previous <span class="-lnav_log-level-styles_warning">warning</span> |
+
+To complete this step in the tutorial, you'll need to navigate to the
+errors and warnings in the sample log file. You can check the upper-right
+↗↗↗ status bar for tips on what you need to do next. Now, press `q` to
+switch to the log view and begin navigating the sample log file.
+
+## Step 2
+
+To search for text in files, you can press `/` to enter the search
+prompt. To make it easier to search for text that is on-screen, you
+can press `TAB` to complete values that are shown on screen. For
+example, to search for the UUID "1AF9293A-F42D-4318-BCDF-60234B240955"
+that is in one of the error messages, you can enter "1AF9" and then
+press `TAB` to complete the rest of the UUID.
+
+Press `q` to switch to the log view and try searching for the UUID.
+
+## Step 3
+
+To move to a particular time in the logs, you have a few options:
+
+* The number keys can be used to move to messages at the ten-minute
+ marks within an hour. For example, pressing `2` will move to the
+ first message after the next twenty-minute mark, pressing `3`
+ will move to the next half-hour mark, and so on.
+* Pressing `ENTER` to focus on the breadcrumb bar, then you
+ can press `TAB` (or right-arrow) to move to the time crumb.
+ With the time crumb selected, you can then type in an absolute
+ or relative time. Or, you can use the up and down arrow keys
+ to select a preset relative time.
+* Pressing `:` will activate the command prompt, then you can use
+ the `:goto` command to move to a given timestamp (or line number).
+
+Press `q` to switch to the log view and try moving to different
+times.

+.SH NAME
+lnav \- ncurses-based log file viewer
+.SH SYNOPSIS
+.B lnav
+[\-hVsar] [logfile1 logfile2 ...]
+.SH DESCRIPTION
+The log file navigator, lnav, is an enhanced log file viewer that
+takes advantage of any semantic information that can be gleaned from
+the files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+.SH KEY BINDINGS
+.TP
+?
+View/leave the online help text.
+.TP
+q
+Quit the program.

+# SYNOPSIS
+#
+# AX_CHECK_GNU_MAKE([run-if-true],[run-if-false])
+#
+# DESCRIPTION
+#
+# This macro searches for a GNU version of make. If a match is found:
+#
+# * The makefile variable `ifGNUmake' is set to the empty string, otherwise
+# it is set to "#". This is useful for including a special features in a
+# Makefile, which cannot be handled by other versions of make.
+# * The makefile variable `ifnGNUmake' is set to #, otherwise
+# it is set to the empty string. This is useful for including a special
+# features in a Makefile, which can be handled
+# by other versions of make or to specify else like clause.
+# * The variable `_cv_gnu_make_command` is set to the command to invoke
+# GNU make if it exists, the empty string otherwise.
+# * The variable `ax_cv_gnu_make_command` is set to the command to invoke
+# GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
+# * If GNU Make is found, its version is extracted from the output of
+# `make --version` as the last field of a record of space-separated
+# columns and saved into the variable `ax_check_gnu_make_version`.
+# * Additionally if GNU Make is found, run shell code run-if-true
+# else run shell code run-if-false.
+#
+# Here is an example of its use:
+#
+# Makefile.in might contain:
+#
+# # A failsafe way of putting a dependency rule into a makefile
+# $(DEPEND):
+# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+# @ifGNUmake@ include $(DEPEND)
+# @ifGNUmake@ else
+# fallback code
+# @ifGNUmake@ endif
+#
+# Then configure.in would normally contain:
+#
+# AX_CHECK_GNU_MAKE()
+# AC_OUTPUT(Makefile)
+#
+# Then perhaps to cause gnu make to override any other make, we could do
+# something like this (note that GNU make always looks for GNUmakefile
+# first):
+#
+# if ! test x$_cv_gnu_make_command = x ; then
+# mv Makefile GNUmakefile
+# echo .DEFAULT: > Makefile ;
+# echo \ $_cv_gnu_make_command \$@ >> Makefile;
+# fi
+#
+# Then, if any (well almost any) other make is called, and GNU make also
+# exists, then the other make wraps the GNU make.

+# (Warnings, however, are ignored)
+#
+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

+#
+# If EXTRA-FLAGS is defined, it is added to the linker's default flags
+# when the check is done. The check is thus made with the flags: "LDFLAGS
+# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
+# issue an error when a bad flag is given.

+# SYNOPSIS
+#
+# AX_CHECK_PCRE2([bits], [action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+# Search for an installed libpcre2-8 library. If nothing was specified
+# when calling configure, it searches first in /usr/local and then in
+# /usr, /opt/local and /sw. If the --with-pcre2=DIR is specified, it will
+# try to find it in DIR/include/pcre2.h and DIR/lib/libpcre2-8. If
+# --without-pcre2 is specified, the library is not searched at all.
+#
+# If 'bits' is empty or '8', PCRE2 8-bit character support is checked
+# only. If 'bits' contains '16', PCRE2 8-bit and 16-bit character support
+# are checked. If 'bits' contains '32', PCRE2 8-bit and 32-bit character
+# support are checked. When 'bits' contains both '16' and '32', PCRE2
+# 8-bit, 16-bit, and 32-bit character support is checked.
+#
+# If either the header file (pcre2.h), or the library (libpcre2-8) is not
+# found, or the specified PCRE2 character bit width is not supported,
+# shell commands 'action-if-not-found' is run. If 'action-if-not-found' is
+# not specified, the configuration exits on error, asking for a valid
+# PCRE2 installation directory or --without-pcre2.
+#
+# If both header file and library are found, and the specified PCRE2 bit
+# widths are supported, shell commands 'action-if-found' is run. If
+# 'action-if-found' is not specified, the default action appends
+# '-I${PCRE2_HOME}/include' to CPFLAGS, appends '-L$PCRE2_HOME}/lib' to
+# LDFLAGS, prepends '-lpcre2-8' to LIBS, and calls AC_DEFINE(HAVE_PCRE2).
+# You should use autoheader to include a definition for this symbol in a
+# config.h file. Sample usage in a C/C++ source is as follows:
+#
+# #ifdef HAVE_PCRE2
+# #define PCRE2_CODE_UNIT_WIDTH 8
+# #include <pcre2.h>
+# #endif /* HAVE_PCRE2 */

+# SYNOPSIS
+#
+# AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
+# in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD variables of every
+# build target (program or library) which should be built with code
+# coverage support. Also add rules using AX_ADD_AM_MACRO_STATIC; and
+# $enable_code_coverage which can be used in subsequent configure output.
+# CODE_COVERAGE_ENABLED is defined and substituted, and corresponds to the
+# value of the --enable-code-coverage option, which defaults to being
+# disabled.
+#
+# Test also for gcov program and create GCOV variable that could be
+# substituted.
+#
+# Note that all optimization flags in CFLAGS must be disabled when code
+# coverage is enabled.
+#
+# Usage example:
+#
+# configure.ac:
+#
+# AX_CODE_COVERAGE
+#
+# Makefile.am:
+#
+# include $(top_srcdir)/aminclude_static.am
+#
+# my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
+# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+# clean-local: code-coverage-clean
+# distclean-local: code-coverage-dist-clean
+#
+# This results in a "check-code-coverage" rule being added to any
+# Makefile.am which do "include $(top_srcdir)/aminclude_static.am"
+# (assuming the module has been configured with --enable-code-coverage).
+# Running `make check-code-coverage` in that directory will run the
+# module's test suite (`make check`) and build a code coverage report
+# detailing the code which was touched, then print the URI for the report.
+#
+# This code was derived from Makefile.decl in GLib, originally licensed
+# under LGPLv2.1+.

+#
+# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+# Check for baseline language coverage in the compiler for the specified
+# version of the C++ standard. If necessary, add switches to CXX and
+# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
+# or '14' (for the C++14 standard).
+#
+# The second argument, if specified, indicates whether you insist on an
+# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+# -std=c++11). If neither is specified, you get whatever works, with
+# preference for no added switch, and then for an extended mode.
+#
+# The third argument, if specified 'mandatory' or if left unspecified,
+# indicates that baseline support for the specified C++ standard is
+# required and that the macro should error out if no mode with that
+# support is found. If specified 'optional', then configuration proceeds
+# regardless, after defining HAVE_CXX${VERSION} if and only if a
+# supporting mode is found.

+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
+# The value of these variables can be overridden by the user by specifying
+# a compiler with an environment variable (like you do for standard CC).
+#
+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
+# substituted in the Makefile.

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also to link with them as well. For example, you might link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threaded programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+# SYNOPSIS
+#
+# AX_WITH_CURSES
+#
+# DESCRIPTION
+#
+# This macro checks whether a SysV or X/Open-compatible Curses library is
+# present, along with the associated header file. The NcursesW
+# (wide-character) library is searched for first, followed by Ncurses,
+# then the system-default plain Curses. The first library found is the
+# one returned.
+#
+# The following options are understood: --with-ncursesw, --with-ncurses,
+# --without-ncursesw, --without-ncurses. The "--with" options force the
+# macro to use that particular library, terminating with an error if not
+# found. The "--without" options simply skip the check for that library.
+# The effect on the search pattern is:
+#
+# (no options) - NcursesW, Ncurses, Curses
+# --with-ncurses --with-ncursesw - NcursesW only [*]
+# --without-ncurses --with-ncursesw - NcursesW only [*]
+# --with-ncursesw - NcursesW only [*]
+# --with-ncurses --without-ncursesw - Ncurses only [*]
+# --with-ncurses - NcursesW, Ncurses [**]
+# --without-ncurses --without-ncursesw - Curses only
+# --without-ncursesw - Ncurses, Curses
+# --without-ncurses - NcursesW, Curses
+#
+# [*] If the library is not found, abort the configure script.
+#
+# [**] If the second library (Ncurses) is not found, abort configure.
+#
+# The following preprocessor symbols may be defined by this macro if the
+# appropriate conditions are met:
+#
+# HAVE_CURSES - if any SysV or X/Open Curses library found
+# HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions
+# HAVE_CURSES_COLOR - if library supports color (enhanced functions)
+# HAVE_CURSES_OBSOLETE - if library supports certain obsolete features
+# HAVE_NCURSESW - if NcursesW (wide char) library is to be used
+# HAVE_NCURSES - if the Ncurses library is to be used
+#
+# HAVE_CURSES_H - if <curses.h> is present and should be used
+# HAVE_NCURSESW_H - if <ncursesw.h> should be used
+# HAVE_NCURSES_H - if <ncurses.h> should be used
+# HAVE_NCURSESW_CURSES_H - if <ncursesw/curses.h> should be used
+# HAVE_NCURSES_CURSES_H - if <ncurses/curses.h> should be used
+#
+# (These preprocessor symbols are discussed later in this document.)
+#
+# The following output variable is defined by this macro; it is precious
+# and may be overridden on the ./configure command line:
+#
+# CURSES_LIB - library to add to xxx_LDADD
+#
+# The library listed in CURSES_LIB is NOT added to LIBS by default. You
+# need to add CURSES_LIB to the appropriate xxx_LDADD line in your
+# Makefile.am. For example:
+#
+# prog_LDADD = @CURSES_LIB@
+#
+# If CURSES_LIB is set on the configure command line (such as by running
+# "./configure CURSES_LIB=-lmycurses"), then the only header searched for
+# is <curses.h>. The user may use the CPPFLAGS precious variable to
+# override the standard #include search path. If the user needs to
+# specify an alternative path for a library (such as for a non-standard
+# NcurseW), the user should use the LDFLAGS variable.
+#
+# The following shell variables may be defined by this macro:
+#
+# ax_cv_curses - set to "yes" if any Curses library found
+# ax_cv_curses_enhanced - set to "yes" if Enhanced functions present
+# ax_cv_curses_color - set to "yes" if color functions present
+# ax_cv_curses_obsolete - set to "yes" if obsolete features present
+#
+# ax_cv_ncursesw - set to "yes" if NcursesW library found
+# ax_cv_ncurses - set to "yes" if Ncurses library found
+# ax_cv_plaincurses - set to "yes" if plain Curses library found
+# ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no"
+#
+# These variables can be used in your configure.ac to determine the level
+# of support you need from the Curses library. For example, if you must
+# have either Ncurses or NcursesW, you could include:
+#
+# AX_WITH_CURSES
+# if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
+# AX_MSG_ERROR([requires either NcursesW or Ncurses library])
+# fi
+#
+# If any Curses library will do (but one must be present and must support
+# color), you could use:
+#
+# AX_WITH_CURSES
+# if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
+# AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
+# fi
+#
+# Certain preprocessor symbols and shell variables defined by this macro
+# can be used to determine various features of the Curses library. In
+# particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
+# library found conforms to the traditional SysV and/or X/Open Base Curses
+# definition. Any working Curses library conforms to this level.
+#
+# HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
+# library supports the X/Open Enhanced Curses definition. In particular,
+# the wide-character types attr_t, cchar_t and wint_t, the functions
+# wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
+# are checked. The Ncurses library does NOT conform to this definition,
+# although NcursesW does.
+#
+# HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
+# supports color functions and macros such as COLOR_PAIR, A_COLOR,
+# COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the
+# X/Open Base Curses definition, but are part of the Enhanced set of
+# functions. The Ncurses library DOES support these functions, as does
+# NcursesW.
+#
+# HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
+# library supports certain features present in SysV and BSD Curses but not
+# defined in the X/Open definition. In particular, the functions
+# getattrs(), getcurx() and getmaxx() are checked.
+#
+# To use the HAVE_xxx_H preprocessor symbols, insert the following into
+# your system.h (or equivalent) header file:
+#
+# #if defined HAVE_NCURSESW_CURSES_H
+# # include <ncursesw/curses.h>
+# #elif defined HAVE_NCURSESW_H
+# # include <ncursesw.h>
+# #elif defined HAVE_NCURSES_CURSES_H
+# # include <ncurses/curses.h>
+# #elif defined HAVE_NCURSES_H
+# # include <ncurses.h>
+# #elif defined HAVE_CURSES_H
+# # include <curses.h>
+# #else
+# # error "SysV or X/Open-compatible Curses header file required"
+# #endif
+#
+# For previous users of this macro: you should not need to change anything
+# in your configure.ac or Makefile.am, as the previous (serial 10)
+# semantics are still valid. However, you should update your system.h (or
+# equivalent) header file to the fragment shown above. You are encouraged
+# also to make use of the extended functionality provided by this version
+# of AX_WITH_CURSES, as well as in the additional macros
+# AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.

+# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
+# [ACTION-IF-YES], [ACTION-IF-NO])
+# ----------------------------------------------------------
+# David Shaw <dshaw@jabberwocky.com> May-09-2006
+#
+# Checks for libcurl. DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-libcurl or --without-libcurl.
+# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
+# minimum version of libcurl to accept. Pass the version as a regular
+# version number like 7.10.1. If not supplied, any version is
+# accepted. ACTION-IF-YES is a list of shell commands to run if
+# libcurl was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-libcurl does run ACTION-IF-NO.
+#
+# This macro #defines HAVE_LIBCURL if a working libcurl setup is
+# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
+# values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
+# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
+# where yyy are the various protocols supported by libcurl. Both xxx
+# and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
+# the macro for the complete list of possible defines. Shell
+# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
+# defined to 'yes' for those features and protocols that were found.
+# Note that xxx and yyy keep the same capitalization as in the
+# curl-config list (e.g. it's "HTTP" and not "http").
+#
+# Users may override the detected values by doing something like:
+# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
+#
+# For the sake of sanity, this macro assumes that any libcurl that is
+# found is after version 7.7.2, the first version that included the
+# curl-config script. Note that it is very important for people
+# packaging binary versions of libcurl to include this script!
+# Without curl-config, we can only guess what protocols are available,
+# or use curl_version_info to figure it out at runtime.

+This library will provide common mathematical and string functions in
+SQL queries using the operating system libraries or provided
+definitions. It includes the following functions:
+
+Math: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference,
+degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp,
+log, log10, power, sign, sqrt, square, ceil, floor, pi.
+
+String: replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim,
+replace, reverse, proper, padl, padr, padc, strfilter.
+
+Aggregate: stdev, variance, mode, median, lower_quartile,
+upper_quartile.
+
+The string functions ltrim, rtrim, trim, replace are included in
+recent versions of SQLite and so by default do not build.
+
+Compilation instructions:
+ Compile this C source file into a dynamic library as follows:
+ * Linux:
+ gcc -fPIC -lm -shared extension-functions.c -o libsqlitefunctions.so
+ * Mac OS X:
+ gcc -fno-common -dynamiclib extension-functions.c -o libsqlitefunctions.dylib
+ (You may need to add flags
+ -I /opt/local/include/ -L/opt/local/lib -lsqlite3
+ if your sqlite3 is installed from Mac ports, or
+ -I /sw/include/ -L/sw/lib -lsqlite3
+ if installed with Fink.)
+ * Windows:
+ 1. Install MinGW (http://www.mingw.org/) and you will get the gcc
+ (gnu compiler collection)
+ 2. add the path to your path variable (isn't done during the
+ installation!)
+ 3. compile:
+ gcc -shared -I "path" -o libsqlitefunctions.so extension-functions.c
+ (path = path of sqlite3ext.h; i.e. C:\programs\sqlite)
+
+Usage instructions for applications calling the sqlite3 API functions:
+ In your application, call sqlite3_enable_load_extension(db,1) to
+ allow loading external libraries. Then load the library libsqlitefunctions
+ using sqlite3_load_extension; the third argument should be 0.
+ See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
+ Select statements may now use these functions, as in
+ SELECT cos(radians(inclination)) FROM satsum WHERE satnum = 25544;
+
+Usage instructions for the sqlite3 program:
+ If the program is built so that loading extensions is permitted,
+ the following will work:
+ sqlite> SELECT load_extension('./libsqlitefunctions.so');
+ sqlite> select cos(radians(45));
+ 0.707106781186548
+ Note: Loading extensions is by default prohibited as a
+ security measure; see "Security Considerations" in
+ http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
+ If the sqlite3 program and library are built this
+ way, you cannot use these functions from the program, you
+ must write your own program using the sqlite3 API, and call
+ sqlite3_enable_load_extension as described above, or else
+ rebuilt the sqlite3 program to allow loadable extensions.
+
+Alterations:
+The instructions are for Linux, Mac OS X, and Windows; users of other
+OSes may need to modify this procedure. In particular, if your math
+library lacks one or more of the needed trig or log functions, comment
+out the appropriate HAVE_ #define at the top of file. If you do not
+wish to make a loadable module, comment out the define for
+COMPILE_SQLITE_EXTENSIONS_AS_LOADABLE_MODULE. If you are using a
+version of SQLite without the trim functions and replace, comment out
+the HAVE_TRIM #define.

+
+History:
+2010-01-06 Correct check for argc in squareFunc, and add Windows
+compilation instructions.
+2009-06-24 Correct check for argc in properFunc.
+2008-09-14 Add check that memory was actually allocated after
+sqlite3_malloc or sqlite3StrDup, call sqlite3_result_error_nomem if
+not. Thanks to Robert Simpson.
+2008-06-13 Change to instructions to indicate use of the math library
+and that program might work.
+2007-10-01 Minor clarification to instructions.
+2007-09-29 Compilation as loadable module is optional with
+COMPILE_SQLITE_EXTENSIONS_AS_LOADABLE_MODULE.
+2007-09-28 Use sqlite3_extension_init and macros
+SQLITE_EXTENSION_INIT1, SQLITE_EXTENSION_INIT2, so that it works with
+sqlite3_load_extension. Thanks to Eric Higashino and Joe Wilson.
+New instructions for Mac compilation.
+2007-09-17 With help from Joe Wilson and Nuno Luca, made use of
+external interfaces so that compilation is no longer dependent on
+SQLite source code. Merged source, header, and README into a single
+file. Added casts so that Mac will compile without warnings (unsigned
+and signed char).
+2007-09-05 Included some definitions from sqlite 3.3.13 so that this
+will continue to work in newer versions of sqlite. Completed
+description of functions available.
+2007-03-27 Revised description.
+2007-03-23 Small cleanup and a bug fix on the code. This was mainly
+letting errno flag errors encountered in the math library and checking
+the result, rather than pre-checking. This fixes a bug in power that
+would cause an error if any non-positive number was raised to any
+power.
+2007-02-07 posted by Mikey C to sqlite mailing list.

+# lnav
+
+A fancy log file viewer for the terminal.
+
+## Overview
+
+The Logfile Navigator, **lnav**, is an enhanced log file viewer that
+takes advantage of any semantic information that can be gleaned from
+the files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+
+## Opening Paths/URLs
+
+The main arguments to lnav are the local/remote files, directories,
+glob patterns, or URLs to be viewed. If no arguments are given, the
+default syslog file for your system will be opened. These arguments
+will be polled periodically so that any new data or files will be
+automatically loaded. If a previously loaded file is removed or
+replaced, it will be closed and the replacement opened.
+
+Note: When opening SFTP URLs, if the password is not provided for the
+host, the SSH agent can be used to do authentication.
+
+## Options
+
+Lnav takes a list of files to view and/or you can use the flag
+arguments to load well-known log files, such as the syslog log
+files. The flag arguments are:
+
+* `-a` Load all of the most recent log file types.
+* `-r` Recursively load files from the given directory hierarchies.
+* `-R` Load older rotated log files as well.
+
+When using the flag arguments, lnav will look for the files relative
+to the current directory and its parent directories. In other words,
+if you are working within a directory that has the well-known log
+files, those will be preferred over any others.
+
+If you do not want the default syslog file to be loaded when
+no files are specified, you can pass the `-N` flag.
+
+Any files given on the command-line are scanned to determine their log
+file format and to create an index for each line in the file. You do
+not have to manually specify the log file format. The currently
+supported formats are: syslog, apache, strace, tcsh history, and
+generic log files with timestamps.
+
+Lnav will also display data piped in on the standard input. The
+following options are available when doing so:
+
+* `-t` Prepend timestamps to the lines of data being read in
+ on the standard input.
+* `-w file` Write the contents of the standard input to this file.
+
+To automatically execute queries or lnav commands after the files
+have been loaded, you can use the following options:
+
+* `-c cmd` A command, query, or file to execute. The first character
+ determines the type of operation: a colon (`:`) is used for the
+ built-in commands; a semi-colon (`;`) for SQL queries; and a
+ pipe symbol (`|`) for executing a file containing other
+ commands. For example, to open the file "foo.log" and go
+ to the tenth line in the file, you can do:
+
+ ```shell
+ lnav -c ':goto 10' foo.log
+ ```
+
+ This option can be given multiple times to execute multiple
+ operations in sequence.
+* `-f file` A file that contains commands, queries, or files to execute.
+ This option is a shortcut for `-c '|file'`. You can use a dash
+ (`-`) to execute commands from the standard input.
+
+To execute commands/queries without opening the interactive text UI,
+you can pass the `-n` option. This combination of options allows you to
+write scripts for processing logs with lnav. For example, to get a list
+of IP addresses that dhclient has bound to in CSV format:
+
+```lnav
+#! /usr/bin/lnav -nf
+
+# Usage: dhcp_ip.lnav /var/log/messages
+# Only include lines that look like:
+# Apr 29 00:31:56 example-centos5 dhclient: bound to 10.1.10.103 -- renewal in 9938 seconds.
+
+:filter-in dhclient: bound to
+
+# The log message parser will extract the IP address
+# as col_0, so we select that and alias it to "dhcp_ip".
+;SELECT DISTINCT col_0 AS dhcp_ip FROM logline;
+
+# Finally, write the results of the query to stdout.
+:write-csv-to -
+```
+
+## Display
+
+The main part of the display shows the log lines from the files interleaved
+based on time-of-day. New lines are automatically loaded as they are appended
+to the files and, if you are viewing the bottom of the files, lnav will scroll
+down to display the new lines, much like `tail -f`.
+
+On color displays, the lines will be highlighted as follows:
+
+* Errors will be colored in <span class="-lnav_log-level-styles_error">red</span>;
+* warnings will be <span class="-lnav_log-level-styles_warning">yellow</span>;
+* boundaries between days will be ${ansi_underline}underlined${ansi_norm}; and
+* various color highlights will be applied to: IP addresses, SQL keywords,
+ XML tags, file and line numbers in Java backtraces, and quoted strings.
+
+To give you an idea of where you are spatially, the right side of the
+display has a proportionally sized 'scroll bar' that indicates your
+current position in the files. The scroll bar will also show areas of
+the file where warnings or errors are detected by coloring the bar
+yellow or red, respectively. Tick marks will also be added to the
+left and right-hand side of the bar, for search hits and bookmarks.
+
+The bar on the left side indicates the file the log message is from. A
+break in the bar means that the next log message comes from a different
+file. The color of the bar is derived from the file name. Pressing the
+left-arrow or `h` will reveal the source file names for each message and
+pressing again will show the full paths.
+
+Above and below the main body are status lines that display a variety
+of information. The top line displays:
+
+* The current time, configurable by the `/ui/clock-format` property.
+* The highest priority message from the `lnav_user_notifications` table.
+ You can insert rows into this table to display your own status messages.
+ The default message displayed on startup explains how to focus on the
+ next status line at the top, which is an interactive breadcrumb bar.
+
+The second status line at the top display breadcrumbs for the top line
+in the main view. Pressing `ENTER` will focus input on the breadcrumb
+bar, the cursor keys can be used to select a breadcrumb. The common
+breadcrumbs are:
+
+* The name of the current view.
+* In the log view, the timestamp of the top log message.
+* In the log view, the format of the log file the top log message is from.
+* The name of the file the top line was pulled from.
+* If the top line is within a larger chunk of structured data, the path to
+ the value in the top line will be shown.
+
+Notes:
+
+1. Pressing `CTRL-A`/`CTRL-E` will select the first/last breadcrumb.
+1. Typing text while a breadcrumb is selected will perform a fuzzy
+ search on the possibilities.
+
+The bottom status bar displays:
+
+* The line number for the top line in the display.
+* The current search hit, the total number of hits, and the search term.
+
+If the view supports filtering, there will be a status line showing the
+following:
+
+* The number of enabled filters and the total number of filters.
+* The number of lines not displayed because of filtering.
+
+To edit the filters, you can press TAB to change the focus from the main
+view to the filter editor. The editor allows you to create, enable/disable,
+and delete filters easily.
+
+Along with filters, a "Files" panel will also be available for viewing
+and controlling the files that lnav is currently monitoring.
+
+Finally, the last line on the display is where you can enter search
+patterns and execute internal commands, such as converting a
+unix-timestamp into a human-readable date. The command-line is
+implemented using the readline library, so the usual set of keyboard
+shortcuts are available. Most commands and searches also support
+tab-completion.
+
+The body of the display is also used to display other content, such
+as: the help file, histograms of the log messages over time, and
+SQL results. The views are organized into a stack so that any time
+you activate a new view with a key press or command, the new view
+is pushed onto the stack. Pressing the same key again will pop the
+view off of the stack and return you to the previous view. Note
+that you can always use `q` to pop the top view off of the stack.
+
+## Default Key Bindings
+
+### Views
+
+| Key(s) | Action |
+| ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **?** | View/leave this help message. |
+| **q** | Leave the current view or quit the program when in the log file view. |
+| Q | Similar to `q`, except it will try to sync the top time between the current and former views. For example, when leaving the spectrogram view with `Q`, the top time in that view will be matched to the top time in the log view. |
+| TAB | Toggle focusing on the filter editor or the main view. |
+| ENTER | Focus on the breadcrumb bar. |
+| a/A | Restore the view that was previously popped with `q`/`Q`. The `A` hotkey will try to match the top times between the two views. |
+| X | Close the current text file or log file. |
+
+### Spatial Navigation
+
+| Key(s) | Action |
+| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| g/Home | Move to the top of the file. |
+| G/End | Move to the end of the file. If the view is already at the end, it will move to the last line. |
+| SPACE/PgDn | Move down a page. |
+| b/PgUp | Move up a page. |
+| j/&DownArrow; | Move down a line. |
+| k/&UpArrow; | Move up a line. |
+| h/&LeftArrow; | Move to the left. In the log view, moving left will reveal the source log file names for each line. Pressing again will reveal the full path. |
+| l/&RightArrow; | Move to the right. |
+| H/Shift &LeftArrow; | Move to the left by a smaller increment. |
+| L/Shift &RightArrow; | Move to the right by a smaller increment. |
+| e/E | Move to the next/previous error. |
+| w/W | Move to the next/previous warning. |
+| n/N | Move to the next/previous search hit. When pressed repeatedly within a short time, the view will move at least a full page at a time instead of moving to the next hit. |
+| f/F | Move to the next/previous file. In the log view, this moves to the next line from a different file. In the text view, this rotates the view to the next file. |
+| &gt;/&lt; | Move horizontally to the next/previous search hit. |
+| o/O | Move forward/backward to the log message with a matching 'operation ID' (opid) field. |
+| u/U | Move forward/backward through any user bookmarks you have added using the 'm' key. This hotkey will also jump to the start of any log partitions that have been created with the 'partition-name' command. |
+| s/S | Move to the next/previous "slow down" in the log message rate. A slow down is detected by measuring how quickly the message rate has changed over the previous several messages. For example, if one message is logged every second for five seconds and then the last message arrives five seconds later, the last message will be highlighted as a slow down. |
+| {/} | Move to the previous/next location in history. Whenever you jump to a new location in the view, the location will be added to the history. The history is not updated when using only the arrow keys. |
+
+### Chronological Navigation
+
+| Key(s) | Action |
+| ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| d/D | Move forward/backward 24 hours from the current position in the log file. |
+| 1-6/Shift 1-6 | Move to the next/previous n'th ten minute of the hour. For example, '4' would move to the first log line in the fortieth minute of the current hour in the log. And, '6' would move to the next hour boundary. |
+| 7/8 | Move to the previous/next minute. |
+| 0/Shift 0 | Move to the next/previous day boundary. |
+| r/R | Move forward/backward based on the relative time that was last used with the 'goto' command. For example, executing ':goto a minute later' will move the log view forward a minute and then pressing 'r' will move it forward a minute again. Pressing 'R' will then move the view in the opposite direction, so backwards a minute. |
+
+### Bookmarks
+
+| Key(s) | Action |
+| ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| m | Mark/unmark the line at the top of the display. The line will be highlighted with reverse video to indicate that it is a user bookmark. You can use the `u` hotkey to iterate through marks you have added. |
+| M | Mark/unmark all the lines between the top of the display and the last line marked/unmarked. |
+| J | Mark/unmark the next line after the previously marked line. |
+| K | Like `J` except it toggles the mark on the previous line. |
+| c | Copy the marked text to the X11 selection buffer or OS X clipboard. |
+| C | Clear all marked lines. |
+
+### Display options
+
+| Key(s) | Action |
+| ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| P | Switch to/from the pretty-printed view of the log or text files currently displayed. In this view, structured data, such as XML, will be reformatted to make it easier to read. |
+| t | Switch to/from the text file view. The text file view is for any files that are not recognized as log files. |
+| = | Pause/unpause loading of new file data. |
+| Ctrl-L | (Lo-fi mode) Exit screen-mode and write the displayed log lines in plain text to the terminal until a key is pressed. Useful for copying long lines from the terminal without picking up any of the extra decorations. |
+| T | Toggle the display of the "elapsed time" column that shows the time elapsed since the beginning of the logs or the offset from the previous bookmark. Sharp changes in the message rate are highlighted by coloring the separator between the time column and the log message. A red highlight means the message rate has slowed down and green means it has sped up. You can use the "s/S" hotkeys to scan through the slow downs. |
+| i | View/leave a histogram of the log messages over time. The histogram counts the number of displayed log lines for each bucket of time. The bars are layed out horizontally with colored segments representing the different log levels. You can use the `z` hotkey to change the size of the time buckets (e.g. ten minutes, one hour, one day). |
+| I | Switch between the log and histogram views while keeping the time displayed at the top of each view in sync. For example, if the top line in the log view is "11:40", hitting `I` will switch to the histogram view and scrolled to display "11:00" at the top (if the zoom level is hours). |
+| z/Shift Z | Zoom in or out one step in the histogram view. |
+| v | Switch to/from the SQL result view. |
+| V | Switch between the log and SQL result views while keeping the top line number in the log view in sync with the log_line column in the SQL view. For example, doing a query that selects for "log_idle_msecs" and "log_line", you can move the top of the SQL view to a line and hit 'V' to switch to the log view and move to the line number that was selected in the "log_line" column. If there is no "log_line" column, lnav will find the first column with a timestamp and move to corresponding time in the log view. |
+| TAB/Shift TAB | In the SQL result view, cycle through the columns that are graphed. Initially, all number values are displayed in a stacked graph. Pressing TAB will change the display to only graph the first column. Repeatedly pressing TAB will cycle through the columns until they are all graphed again. |
+| p | In the log view: enable or disable the display of the fields that the log message parser knows about or has discovered. This overlay is temporarily enabled when the semicolon key (;) is pressed so that it is easier to write queries. |
+| | In the DB view: enable or disable the display of values in columns containing JSON-encoded values in the top row. The overlay will display the JSON-Pointer reference and value for all fields in the JSON data. |
+| CTRL-W | Toggle word-wrapping. |
+| CTRL-P | Show/hide the data preview panel that may be opened when entering commands or SQL queries. |
+| CTRL-F | Toggle the enabled/disabled state of all filters in the current view. |
+| x | Toggle the hiding of log message fields. The hidden fields will be replaced with three bullets and highlighted in yellow. |
+| F2 | Toggle mouse support. |
+
+### Query
+
+| Key(s) | Action |
+| -------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **/**_regexp_ | Start a search for the given regular expression. The search is live, so when there is a pause in typing, the currently running search will be canceled and a new one started. The first ten lines that match the search will be displayed in the preview window at the bottom of the view. History is maintained for your searches so you can rerun them easily. Words that are currently displayed are also available for tab-completion, so you can easily search for values without needing to copy-and-paste the string. If there is an error encountered while trying to interpret the expression, the error will be displayed in red on the status line. While the search is active, the 'hits' field in the status line will be green, when finished it will turn back to black. |
+| **:**&lt;command&gt; | Execute an internal command. The commands are listed below. History is also supported in this context as well as tab-completion for commands and some arguments. The result of the command replaces the command you typed. |
+| **;**&lt;sql&gt; | Execute an SQL query. Most supported log file formats provide a sqlite virtual table backend that can be used in queries. See the SQL section below for more information. |
+| **&VerticalLine;**&lt;script&gt; [arg1...] | Execute an lnav script contained in a format directory (e.g. \~/.lnav/formats/default). The script can contain lines starting with `:`, `;`, or `\|` to execute commands, SQL queries or execute other files in lnav. Any values after the script name are treated as arguments can be referenced in the script using `\$1`, `\$2`, and so on, like in a shell script. |
+| CTRL+], ESCAPE | Abort command-line entry started with `/`, `:`, `;`, or `\|`. |
+
+> **Note**: The regular expression format used by lnav is
+> [PCRE](http://perldoc.perl.org/perlre.html)
+> (Perl-Compatible Regular Expressions).
+>
+> If the search string is not valid PCRE, a search
+> is done for the exact string instead of doing a
+> regex search.
+
+## Session
+
+| Key(s) | Action |
+| ------ | ---------------------------------------------------------------------------------------------------------------------------------------- |
+| CTRL-R | Reset the session state. This will save the current session state (filters, highlights) and then reset the state to the factory default. |
+
+## Filter Editor
+
+The following hotkeys are only available when the focus is on the filter
+editor. You can change the focus by pressing TAB.
+
+| Key(s) | Action |
+| ------------- | ------------------------------------------------------------------- |
+| q | Switch the focus back to the main view. |
+| j/&DownArrow; | Select the next filter. |
+| k/&UpArrow; | Select the previous filter. |
+| o | Create a new "out" filter. |
+| i | Create a new "in" filter . |
+| SPACE | Toggle the enabled/disabled state of the currently selected filter. |
+| t | Toggle the type of filter between "in" and "out". |
+| ENTER | Edit the selected filter. |
+| D | Delete the selected filter. |
+
+## Mouse Support (experimental)
+
+If you are using Xterm, or a compatible terminal, you can use the mouse to
+mark lines of text and move the view by grabbing the scrollbar.
+
+NOTE: You need to manually enable this feature by setting the LNAV_EXP
+environment variable to "mouse". F2 toggles mouse support.
+
+## SQL Queries (experimental)
+
+Lnav has support for performing SQL queries on log files using the
+Sqlite3 "virtual" table feature. For all supported log file types,
+lnav will create tables that can be queried using the subset of SQL
+that is supported by Sqlite3. For example, to get the top ten URLs
+being accessed in any loaded Apache log files, you can execute:
+
+```lnav
+;SELECT cs_uri_stem, count(*) AS total FROM access_log
+ GROUP BY cs_uri_stem ORDER BY total DESC LIMIT 10;
+```
+
+The query result view shows the results and graphs any numeric
+values found in the result, much like the histogram view.
+
+The builtin set of log tables are listed below. Note that only the
+log messages that match a particular format can be queried by a
+particular table. You can find the file format and table name for
+the top log message by looking in the upper right hand corner of the
+log file view.
+
+Some commonly used format tables are:
+
+| Name | Description |
+| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
+| access_log | Apache common access log format |
+| syslog_log | Syslog format |
+| strace_log | Strace log format |
+| generic_log | 'Generic' log format. This table contains messages from files that have a very simple format with a leading timestamp followed by the message. |
+
+NOTE: You can get a dump of the schema for the internal tables, and
+any attached databases, by running the `.schema` SQL command.
+
+The columns available for the top log line in the view will
+automatically be displayed after pressing the semicolon (`;`) key.
+All log tables contain at least the following columns:
+
+| Column | Description |
+| -------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| log_line | The line number in the file, starting at zero. |
+| log_part | The name of the partition. You can change this column using an UPDATE SQL statement or with the 'partition-name' command. After a value is set, the following log messages will have the same partition name up until another name is set. |
+| log_time | The time of the log entry. |
+| log_idle_msecs | The amount of time, in milliseconds, between the current log message and the previous one. |
+| log_level | The log level (e.g. info, error, etc...). |
+| log_mark | The bookmark status for the line. This column can be written to using an UPDATE query. |
+| log_path | The full path to the file. |
+| log_text | The raw line of text. Note that this column is not included in the result of a 'select *', but it does exist. |
+
+The following tables include the basic columns as listed above and
+include a few more columns since the log file format is more
+structured.
+
+* `syslog_log`
+
+ | Column | Description |
+ | ------------ | ---------------------------------------------------- |
+ | log_hostname | The hostname the message was received from. |
+ | log_procname | The name of the process that sent the message. |
+ | log_pid | The process ID of the process that sent the message. |
+
+* `access_log` (The column names are the same as those in the
+ Microsoft LogParser tool.)
+
+ | Column | Description |
+ | ------------- | ----------------------------------------- |
+ | c_ip | The client IP address. |
+ | cs_username | The client user name. |
+ | cs_method | The HTTP method. |
+ | cs_uri_stem | The stem portion of the URI. |
+ | cs_uri_query | The query portion of the URI. |
+ | cs_version | The HTTP version string. |
+ | sc_status | The status number returned to the client. |
+ | sc_bytes | The number of bytes sent to the client. |
+ | cs_referrer | The URL of the referring page. |
+ | cs_user_agent | The user agent string. |
+
+* `strace_log` (Currently, you need to run strace with the `-tt -T`
+ options so there are timestamps for each function call.)
+
+ | Column | Description |
+ | ----------- | ---------------------------------------- |
+ | funcname | The name of the syscall. |
+ | result | The result code. |
+ | duration | The amount of time spent in the syscall. |
+ | arg0 - arg9 | The arguments passed to the syscall. |
+
+These tables are created dynamically and not stored in memory or on
+disk. If you would like to persist some information from the tables,
+you can attach another database and create tables in that database.
+For example, if you wanted to save the results from the earlier
+example of a top ten query into the "/tmp/topten.db" file, you can do:
+
+```lnav
+;ATTACH DATABASE '/tmp/topten.db' AS topten;
+;CREATE TABLE topten.foo AS SELECT cs_uri_stem, count(*) AS total
+ FROM access_log GROUP BY cs_uri_stem ORDER BY total DESC
+ LIMIT 10;
+```
+
+## Dynamic logline Table (experimental)
+
+(NOTE: This feature is still very new and not completely reliable yet,
+use with care.)
+
+For log formats that lack message structure, lnav can parse the log
+message and attempt to extract any data fields that it finds. This
+feature is available through the `logline` log table. This table is
+dynamically created and defined based on the message at the top of
+the log view. For example, given the following log message from "sudo",
+lnav will create the "logline" table with columns for "TTY", "PWD",
+"USER", and "COMMAND":
+
+```
+May 24 06:48:38 Tim-Stacks-iMac.local sudo[76387]: stack : TTY=ttys003 ; PWD=/Users/stack/github/lbuild ; USER=root ; COMMAND=/bin/echo Hello, World!
+```
+
+Queries executed against this table will then only return results for
+other log messages that have the same format. So, if you were to
+execute the following query while viewing the above line, you might
+get the following results:
+
+```lnav
+;SELECT USER,COMMAND FROM logline;
+```
+
+| USER | COMMAND |
+| ---- | ------------------------- |
+| root | /bin/echo Hello, World! |
+| mal | /bin/echo Goodbye, World! |
+
+The log parser works by examining each message for key/value pairs
+separated by an equal sign (=) or a colon (:). For example, in the
+previous example of a "sudo" message, the parser sees the "USER=root"
+string as a pair where the key is "USER" and the value is "root".
+If no pairs can be found, then anything that looks like a value is
+extracted and assigned a numbered column. For example, the following
+line is from "dhcpd":
+
+```
+Sep 16 22:35:57 drill dhcpd: DHCPDISCOVER from 00:16:ce:54:4e:f3 via hme3
+```
+
+In this case, the lnav parser recognizes that "DHCPDISCOVER", the MAC
+address and the "hme3" device name are values and not normal words. So,
+it builds a table with three columns for each of these values. The
+regular words in the message, like "from" and "via", are then used to
+find other messages with a similar format.
+
+If you would like to execute queries against log messages of different
+formats at the same time, you can use the 'create-logline-table' command
+to permanently create a table using the top line of the log view as a
+template.
+
+## Other SQL Features
+
+Environment variables can be used in SQL statements by prefixing the
+variable name with a dollar-sign (\$). For example, to read the value of
+the `HOME` variable, you can do:
+
+```lnav
+;SELECT \$HOME;
+```
+
+To select the syslog messages that have a hostname field that is equal
+to the `HOSTNAME` variable:
+
+```lnav
+;SELECT * FROM syslog_log WHERE log_hostname = \$HOSTNAME;
+```
+
+NOTE: Variable substitution is done for fields in the query and is not
+a plain text substitution. For example, the following statement
+WILL NOT WORK:
+
+```lnav
+;SELECT * FROM \$TABLE_NAME; -- Syntax error
+```
+
+Access to lnav's environment variables is also available via the "environ"
+table. The table has two columns (name, value) and can be read and written
+to using SQL SELECT, INSERT, UPDATE, and DELETE statements. For example,
+to set the "FOO" variable to the value "BAR":
+
+```lnav
+;INSERT INTO environ SELECT 'FOO', 'BAR';
+```
+
+As a more complex example, you can set the variable "LAST" to the last
+syslog line number by doing:
+
+```lnav
+;INSERT INTO environ SELECT 'LAST', (SELECT max(log_line) FROM syslog_log);
+```
+
+A delete will unset the environment variable:
+
+```lnav
+;DELETE FROM environ WHERE name='LAST';
+```
+
+The table allows you to easily use the results of a SQL query in lnav
+commands, which is especially useful when scripting lnav.

+
+ lnav - A fancy log file viewer
+
+DESCRIPTION
+===========
+
+The log file navigator, lnav, is an enhanced log file viewer that
+takes advantage of any semantic information that can be gleaned from
+the files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+
+
+OPENING PATHS/URLs
+==================
+
+The main arguments to lnav are the files, directories, glob patterns,
+or URLs to be viewed. If no arguments are given, the default syslog
+file for your system will be opened. These arguments will be polled
+periodically so that any new data or files will be automatically
+loaded. If a previously loaded file is removed or replaced, it will
+be closed and the replacement opened.
+
+Note: When opening SFTP URLs, if the password is not provided for the
+host, the SSH agent can be used to do authentication.
+
+
+OPTIONS
+=======
+
+Lnav takes a list of files to view and/or you can use the flag
+arguments to load well-known log files, such as the syslog log
+files. The flag arguments are:
+
+ -a Load all of the most recent log file types.
+ -r Recursively load files from the given directory hierarchies.
+ -R Load older rotated log files as well.
+
+When using the flag arguments, lnav will look for the files relative
+to the current directory and its parent directories. In other words,
+if you are working within a directory that has the well-known log
+files, those will be preferred over any others.
+
+If you do not want the default syslog file to be loaded when
+no files are specified, you can pass the '-N' flag.
+
+Any files given on the command-line are scanned to determine their log
+file format and to create an index for each line in the file. You do
+not have to manually specify the log file format. The currently
+supported formats are: syslog, apache, strace, tcsh history, and
+generic log files with timestamps.
+
+Lnav will also display data piped in on the standard input. The
+following options are available when doing so:
+
+ -t Prepend timestamps to the lines of data being read in
+ on the standard input.
+ -w file Write the contents of the standard input to this file.
+
+To automatically execute queries or lnav commands after the files
+have been loaded, you can use the following options:
+
+ -c cmd A command, query, or file to execute. The first character
+ determines the type of operation: a colon is used for the
+ built-in commands; a semi-colon for SQL queries; and a
+ pipe symbol (|) for executing a file containing other
+ commands. For example, to open the file "foo.log" and go
+ to the tenth line in the file, you can do:
+
+ lnav -c ':goto 10' foo.log
+
+ This option can be given multiple times to execute multiple
+ operations in sequence.
+
+ -f file A file that contains commands, queries, or files to execute.
+ This option is a shortcut for "-c '|file'". You can use a
+ dash (-) to execute commands from the standard input.
+
+To execute commands/queries without the opening the interactive text UI,
+you can pass the '-n' option. This combination of options allows you to
+write scripts for processing logs with lnav. For example, to get a list
+of IP addresses that dhclient has bound to in CSV format:
+
+ #! /usr/bin/lnav -nf
+
+ # Usage: dhcp_ip.lnav /var/log/messages
+
+ # Only include lines that look like:
+ # Apr 29 00:31:56 example-centos5 dhclient: bound to 10.1.10.103 -- renewal in 9938 seconds.
+ :filter-in dhclient: bound to
+
+ # The log message parser will extract the IP address as col_0, so we
+ # select that and alias it to "dhcp_ip".
+ ;select distinct col_0 as dhcp_ip from logline;
+
+ # Finally, write the results of the query to stdout.
+ :write-csv-to -
+
+
+DISPLAY
+=======
+
+The main part of the display shows the log lines from the files interleaved
+based on time-of-day. New lines are automatically loaded as they are appended
+to the files and, if you are viewing the bottom of the files, lnav will scroll
+down to display the new lines, much like 'tail -f'.
+
+On color displays, the lines will be highlighted as follows:
+
+ * Errors will be colored in ${ansi_red}red${ansi_norm};
+ * warnings will be ${ansi_yellow}yellow${ansi_norm};
+ * boundaries between days will be ${ansi_underline}underlined${ansi_norm}; and
+ * various color highlights will be applied to: IP addresses, SQL keywords,
+ XML tags, file and line numbers in Java backtraces, and quoted strings.
+
+To give you an idea of where you are spatially, the right side of the
+display has a proportionally sized 'scroll bar' that indicates your
+current position in the files. The scroll bar will also show areas of
+the file where warnings or errors are detected by coloring the bar
+yellow or red, respectively. Tick marks will also be added to the
+left and right hand side of the bar, for search hits and bookmarks.
+
+A bar on the left side is color coded and broken up to indicate which
+messages are from the same file. Pressing the left-arrow or 'h' will
+reveal the source file names for each message and pressing again will
+show the full paths.
+
+When at the bottom of the log view, a summary line will be displayed on the
+right-hand-side to give you some more information about your logs, including:
+how long ago the last message was generated, the number of log files, the
+error rate, and how much time the logs cover. The error rate display shows
+the errors-per-minute over the last five minutes. A bar chart is also
+overlaid on the "Error rate" label to show the error rate over the past ten
+seconds. For example, if there have not been many errors in the past five
+minutes and there is a sudden spike, the bar chart will fill up completely.
+But, if there has been a steady stream of errors, then the chart will only
+partially fill based on the recent error frequency.
+
+Above and below the main body are status lines that display:
+
+ * the current time;
+ * the name of the file the top line was pulled from;
+ * the log format for the top line;
+ * the current view;
+ * the line number for the top line in the display;
+ * the current search hit, the total number of hits, and the search term;
+
+If the view supports filtering, there will be a status line showing the
+following:
+
+ * the number of enabled filters and the total number of filters;
+ * the number of lines not displayed because of filtering.
+
+To edit the filters, you can press TAB to change the focus from the main
+view to the filter editor. The editor allows you to create, enable/disable,
+and delete filters easily.
+
+Finally, the last line on the display is where you can enter search
+patterns and execute internal commands, such as converting a
+unix-timestamp into a human-readable date. The command-line is
+implemented using the readline library, so the usual set of keyboard
+shortcuts are available. Most commands and searches also support
+tab-completion.
+
+
+The body of the display is also used to display other content, such
+as: the help file, histograms of the log messages over time, and
+SQL results. The views are organized into a stack so that any time
+you activate a new view with a key press or command, the new view
+is pushed onto the stack. Pressing the same key again will pop the
+view off of the stack and return you to the previous view. Note
+that you can always use 'q' to pop the top view off of the stack.
+
+
+DEFAULT KEY BINDINGS
+====================
+
+Views
+-----
+
+ ? View/leave this help message.
+ q Leave the current view or quit the program when in
+ the log file view.
+ Q Similar to 'q', except it will try to sync the top time
+ between the current and former views. For example, when
+ leaving the spectrogram view with 'Q', the top time in that
+ view will be matched to the top time in the log view.
+
+ TAB Toggle focusing on the filter editor or the main view.
+
+ a/A Restore the view that was previously popped with 'q/Q'.
+ The 'A' hotkey will try to match the top times between the
+ two views.
+
+ X Close the current text file or log file.
+
+Spatial Navigation
+------------------
+
+ g/home Move to the top of the file.
+ G/end Move to the end of the file. If the view is already
+ at the end, it will move to the last line.
+ space/pgdn Move down a page.
+ b/bs/pgup Move up a page.
+ j/cr/down-arrow Move down a line.
+ k/up-arrow Move up a line.
+ h/left-arrow Move to the left. In the log view, moving left will reveal
+ the source log file names for each line. Pressing again
+ will reveal the full path.
+ l/right-arrow Move to the right.
+ H/Shift+left Move to the left by a smaller increment.
+ L/Shift+right Move to the right by a smaller increment.
+
+ e/E Move to the next/previous error.
+ w/W Move to the next/previous warning.
+ n/N Move to the next/previous search hit. When pressed
+ repeatedly within a short time, the view will move at
+ least a full page at a time instead of moving to the
+ next hit.
+ f/F Move to the next/previous file. In the log view, this
+ moves to the next line from a different file. In the
+ text view, this rotates the view to the next file.
+
+ >/< Move horizontally to the next/previous search hit.
+
+ o/O Move forward/backward to the log message with a matching
+ 'operation ID' (opid) field.
+
+ u/U Move forward/backward through any user bookmarks
+ you have added using the 'm' key. This hotkey will
+ also jump to the start of any log partitions that have
+ been created with the 'partition-name' command.
+
+ s/S Move to the next/previous "slow down" in the log message
+ rate. A slow down is detected by measuring how quickly
+ the message rate has changed over the previous several
+ messages. For example, if one message is logged every
+ second for five seconds and then the last message arrives
+ five seconds later, the last message will be highlighted
+ as a slow down.
+
+ {/} Move to the previous/next location in history. Whenever
+ you jump to a new location in the view, the location will
+ be added to the history. The history is not updated when
+ using only the arrow keys.
+
+
+Chronological Navigation
+------------------------
+
+ d/D Move forward/backward 24 hours from the current
+ position in the log file.
+
+ 1-6/Shift 1-6 Move to the next/previous n'th ten minute of the
+ hour. For example, '4' would move to the first
+ log line in the fortieth minute of the current
+ hour in the log. And, '6' would move to the next
+ hour boundary.
+
+ 7/8 Move to the previous/next minute.
+
+ 0/Shift 0 Move to the next/previous day boundary.
+
+ r/R Move forward/backward based on the relative time that
+ was last used with the 'goto' command. For example,
+ executing ':goto a minute later' will move the log view
+ forward a minute and then pressing 'r' will move it
+ forward a minute again. Pressing 'R' will then move the
+ view in the opposite direction, so backwards a minute.
+
+Bookmarks
+---------
+
+ m Mark/unmark the line at the top of the display.
+ The line will be highlighted with reverse video to
+ indicate that it is a user bookmark. You can use
+ the 'u' hotkey to iterate through marks you have
+ added.
+
+ M Mark/unmark all the lines between the top of the
+ display and the last line marked/unmarked.
+
+ J Mark/unmark the next line after the previously
+ marked line.
+
+ K Like 'J' except it toggles the mark on the
+ previous line.
+
+ c Copy the marked text to the X11 selection buffer or OS X
+ clipboard.
+
+ C Clear all marked lines.
+
+Display options
+---------------
+
+ P Switch to/from the pretty-printed view of the log or text
+ files currently displayed. In this view, structured data,
+ such as XML, will be reformatted to make it easier to read.
+
+ t Switch to/from the text file view. The text file view is
+ for any files that are not recognized as log files.
+
+ = Pause/unpause loading of new file data.
+
+ Ctrl-L (Lo-fi mode) Exit screen-mode and write the
+ displayed log lines in plain text to the terminal
+ until a key is pressed. Useful for copying long lines
+ from the terminal without picking up any of the extra
+ decorations.
+
+ T Toggle the display of the "elapsed time" column that shows
+ the time elapsed since the beginning of the logs or the
+ offset from the previous bookmark. Sharp changes in the
+ message rate are highlighted by coloring the separator
+ between the time column and the log message. A red
+ highlight means the message rate has slowed down and green
+ means it has sped up. You can use the "s/S" hotkeys to
+ scan through the slow downs.
+
+ i View/leave a histogram of the log messages over
+ time. The histogram counts the number of
+ displayed log lines for each bucket of time. The
+ bars are layed out horizontally with colored
+ segments representing the different log levels.
+ You can use the 'z' hotkey to change the size of
+ the time buckets (e.g. ten minutes, one hour, one
+ day).
+
+ I Switch between the log and histogram views while
+ keeping the time displayed at the top of each view
+ in sync. For example, if the top line in the log
+ view is "11:40", hitting 'I' will switch to the
+ histogram view and scrolled to display "11:00" at
+ the top (if the zoom level is hours).
+
+ z/Shift Z Zoom in or out one step in the histogram view.
+
+ v Switch to/from the SQL result view.
+
+ V Switch between the log and SQL result views while
+ keeping the top line number in the log view in
+ sync with the log_line column in the SQL view.
+ For example, doing a query that selects for
+ "log_idle_msecs" and "log_line", you can move the
+ top of the SQL view to a line and hit 'V' to switch
+ to the log view and move to the line number that was
+ selected in the "log_line" column. If there is no
+ "log_line" column, lnav will find the first column with
+ a timestamp and move to corresponding time in the log
+ view.
+
+ TAB/Shift+TAB In the SQL result view, cycle through the columns that
+ are graphed. Initially, all number values are displayed
+ in a stacked graph. Pressing TAB will change the display
+ to only graph the first column. Repeatedly pressing TAB
+ will cycle through the columns until they are all graphed
+ again.
+
+ p In the log view: enable or disable the display of the
+ fields that the log message parser knows about or has
+ discovered. This overlay is temporarily enabled when the
+ semicolon key (;) is pressed so that it is easier to write
+ queries.
+
+ In the DB view: enable or disable the display of values
+ in columns containing JSON-encoded values in the top row.
+ The overlay will display the JSON-Pointer reference and
+ value for all fields in the JSON data.
+
+ CTRL-W Toggle word-wrapping.
+
+ CTRL-P Show/hide the data preview panel that may be opened when
+ entering commands or SQL queries.
+
+ CTRL-F Toggle the enabled/disabled state of all filters in the
+ current view.
+
+ x Toggle the hiding of log message fields. The hidden fields
+ will be replaced with three bullets and highlighted in
+ yellow.
+
+ F2 Toggle mouse support.
+
+Query
+-----
+
+ /<regexp> Start a search for the given regular expression.
+ The search is live, so when there is a pause in
+ typing, the currently running search will be
+ canceled and a new one started. The first ten lines
+ that match the search will be displayed in the preview
+ window at the bottom of the view. History is
+ maintained for your searches so you can rerun them
+ easily. Words that are currently displayed are also
+ available for tab-completion, so you can easily
+ search for values without needing to copy-and-paste
+ the string. If there is an error encountered while
+ trying to interpret the expression, the error will
+ be displayed in red on the status line. While the
+ search is active, the 'hits' field in the status
+ line will be green, when finished it will turn
+ back to black.
+
+ Note: The regular expression format used by is PCRE
+ (Perl-Compatible Regular Expressions). For example,
+ if you wanted to search for ethernet device names,
+ regardless of their ID number, you can type:
+
+ eth\\d+
+
+ You can find more information about Perl regular
+ expressions at:
+
+ http://perldoc.perl.org/perlre.html
+
+ If the search string is not valid PCRE, a search
+ is done for the exact string instead of doing a
+ regex search.
+
+ :<command> Execute an internal command. The commands are
+ listed below. History is also supported in this
+ context as well as tab-completion for commands and
+ some arguments. The result of the command
+ replaces the command you typed.
+
+ ;<sql> Execute an SQL query. Most supported log file
+ formats provide a sqlite virtual table backend
+ that can be used in queries. See the SQL section
+ below for more information.
+
+ |<script> [arg1 .. argN]
+ Execute an lnav script contained in a format directory
+ (e.g. \~/.lnav/formats/default). The script can contain
+ lines starting with ':', ';', or '|' to execute commands,
+ SQL queries or execute other files in lnav. Any values
+ after the script name are treated as arguments can be
+ referenced in the script using '\$1', '\$2', and so on, like
+ in a shell script.
+
+ CTRL+], ESCAPE Abort command-line entry started with '/', ':', ';', or '|'.
+
+Session
+-------
+
+ CTRL-R Reset the session state. This will save the current
+ session state (filters, highlights) and then reset the
+ state to the factory default.
+
+Filter Editor
+-------------
+
+The following hotkeys are only available when the focus is on the filter
+editor. You can change the focus by pressing TAB.
+
+ q Switch the focus back to the main view.
+ j/down-arrow Select the next filter.
+ k/up-arrow Select the previous filter.
+ o Create a new "out" filter.
+ i Create a new "in" filter .
+ SPACE Toggle the enabled/disabled state of the currently
+ selected filter.
+ t Toggle the type of filter between "in" and "out".
+ ENTER Edit the selected filter.
+ D Delete the selected filter.
+
+
+MOUSE SUPPORT (experimental)
+============================
+
+If you are using Xterm, or a compatible terminal, you can use the mouse to
+mark lines of text and move the view by grabbing the scrollbar.
+
+NOTE: You need to manually enable this feature by setting the LNAV_EXP
+environment variable to "mouse". F2 toggles mouse support.
+
+
+COMMANDS
+========
+
+ help Switch to this help text view.
+
+ adjust-log-time <date|relative-time>
+ Change the time of the top log line to the given time or
+ adjusted by the relative time. All other log lines in the
+ same file will also be adjusted using the same offset.
+ After the adjustment, the displayed timestamp will be
+ rewritten to the new time and highlighted with a magenta
+ color.
+
+ This command is useful for lining up log files that
+ have timestamps from different machines.
+
+ unix-time <secs-or-date>
+ Convert a unix-timestamp in seconds to a
+ human-readable form or vice-versa.
+ BEWARE OF TIMEZONE DIFFERENCES.
+
+ current-time Print the current time in human-readable form and
+ as a unix-timestamp.
+
+ goto <line#|N%|abs-time|relative-time>
+ Go to the given line number, N percent into the
+ file, or the given timestamp in the log view. If the
+ line number is negative, it is considered an offset
+ from the last line. Relative time values, like
+ 'a minute ago', 'an hour later', and many other formats
+ are supported. When using a relative time, the 'r/R'
+ hotkeys can be used to move the same amount again or in
+ the same amount in the opposite direction.
+
+ relative-goto <line#|N%>
+ Move the current view up or down by the given amount.
+
+ comment <message>
+ Add a comment to the top line in the log view. The
+ comment will be saved in the session and will be available
+ the next time the file is loaded. Searches will also scan
+ the comment for any matches.
+

+
+SQL QUERIES (experimental)
+===========
+
+Lnav has support for performing SQL queries on log files using the
+Sqlite3 "virtual" table feature. For all supported log file types,
+lnav will create tables that can be queried using the subset of SQL
+that is supported by Sqlite3. For example, to get the top ten URLs
+being accessed in any loaded Apache log files, you can execute:
+
+ ;select cs_uri_stem, count(*) as total from access_log
+ group by cs_uri_stem order by total desc limit 10;
+
+The query result view shows the results and graphs any numeric
+values found in the result, much like the histogram view.
+
+The builtin set of log tables are listed below. Note that only the
+log messages that match a particular format can be queried by a
+particular table. You can find the file format and table name for
+the top log message by looking in the upper right hand corner of the
+log file view.
+
+Some commonly used format tables are:
+
+ access_log Apache common access log format
+ syslog_log Syslog format
+ strace_log Strace log format
+ generic_log 'Generic' log format. This table contains messages
+ from files that have a very simple format with a
+ leading timestamp followed by the message.
+
+NOTE: You can get a dump of the schema for the internal tables, and
+any attached databases, by running the '.schema' SQL command.
+
+The columns available for the top log line in the view will
+automatically be displayed after pressing the semicolon (;) key.
+All log tables contain at least the following columns:
+
+ log_line The line number in the file, starting at zero.
+ log_part The name of the partition. You can change this
+ column using an UPDATE SQL statement or with the
+ 'partition-name' command. After a value is set,
+ the following log messages will have the same
+ partition name up until another name is set.
+ log_time The time of the log entry.
+ log_idle_msecs The amount of time, in milliseconds, between the
+ current log message and the previous one.
+ log_level The log level (e.g. info, error, etc...).
+ log_mark The bookmark status for the line. This column
+ can be written to using an UPDATE query.
+ log_path The full path to the file.
+ log_text The raw line of text. Note that this column is
+ not included in the result of a 'select *', but
+ it does exist.
+
+The following tables include the basic columns as listed above and
+include a few more columns since the log file format is more
+structured.
+
+ syslog_log
+
+ log_hostname The hostname the message was received from.
+ log_procname The name of the process that sent the message.
+ log_pid The process ID of the process that sent the message.
+
+ access_log (The column names are the same as those in the
+ Microsoft LogParser tool.)
+
+ c_ip The client IP address.
+ cs_username The client user name.
+ cs_method The HTTP method.
+ cs_uri_stem The stem portion of the URI.
+ cs_uri_query The query portion of the URI.
+ cs_version The HTTP version string.
+ sc_status The status number returned to the client.
+ sc_bytes The number of bytes sent to the client.
+ cs_referrer The URL of the referring page.
+ cs_user_agent The user agent string.
+
+ strace_log (Currently, you need to run strace with the
+ "-tt -T" options so there are timestamps for
+ each function call.)
+
+ funcname The name of the syscall.
+ result The result code.
+ duration The amount of time spent in the syscall.
+ arg0 - arg9 The arguments passed to the syscall.
+
+These tables are created dynamically and not stored in memory or on
+disk. If you would like to persist some information from the tables,
+you can attach another database and create tables in that database.
+For example, if you wanted to save the results from the earlier
+example of a top ten query into the "/tmp/topten.db" file, you can do:
+
+ ;attach database "/tmp/topten.db" as topten;
+ ;create table topten.foo as select cs_uri_stem, count(*) as total
+ from access_log group by cs_uri_stem order by total desc
+ limit 10;
+
+
+DYNAMIC LOG LINE TABLE (experimental)
+======================
+
+(NOTE: This feature is still very new and not completely reliable yet,
+ use with care.)
+
+For log formats that lack message structure, lnav can parse the log
+message and attempt to extract any data fields that it finds. This
+feature is available through the "logline" log table. This table is
+dynamically created and defined based on the message at the top of
+the log view. For example, given the following log message from "sudo",
+lnav will create the "logline" table with columns for "TTY", "PWD",
+"USER", and "COMMAND":
+
+ May 24 06:48:38 Tim-Stacks-iMac.local sudo[76387]: stack : TTY=ttys003 ;
+ PWD=/Users/stack/github/lbuild ; USER=root ;
+ COMMAND=/bin/echo Hello, World!
+
+Queries executed against this table will then only return results for
+other log messages that have the same format. So, if you were to
+execute the following query while viewing the above line, you might
+get the following results:
+
+ ;select USER,COMMAND from logline;
+
+ USER | COMMAND
+ ---- | -------------------------
+ root | /bin/echo Hello, World!
+ mal | /bin/echo Goodbye, World!
+
+
+The log parser works by examining each message for key/value pairs
+separated by an equal sign (=) or a colon (:). For example, in the
+previous example of a "sudo" message, the parser sees the "USER=root"
+string as a pair where the key is "USER" and the value is "root".
+If no pairs can be found, then anything that looks like a value is
+extracted and assigned a numbered column. For example, the following
+line is from "dhcpd":
+
+ Sep 16 22:35:57 drill dhcpd: DHCPDISCOVER from 00:16:ce:54:4e:f3 via hme3
+
+In this case, the lnav parser recognizes that "DHCPDISCOVER", the MAC
+address and the "hme3" device name are values and not normal words. So,
+it builds a table with three columns for each of these values. The
+regular words in the message, like "from" and "via", are then used to
+find other messages with a similar format.
+
+If you would like to execute queries against log messages of different
+formats at the same time, you can use the 'create-logline-table' command
+to permanently create a table using the top line of the log view as a
+template.
+
+
+OTHER SQL FEATURES
+==================
+
+Environment variables can be used in SQL statements by prefixing the
+variable name with a dollar-sign (\$). For example, to read the value of
+the HOME variable, you can do:
+
+ ;SELECT \$HOME;
+
+To select the syslog messages that have a hostname field that is equal
+to the HOSTNAME variable:
+
+ ;SELECT * FROM syslog_log WHERE log_hostname = \$HOSTNAME;
+
+NOTE: Variable substitution is done for fields in the query and is not
+a plain text substitution. For example, the following statement
+WILL NOT WORK:
+
+ ;SELECT * FROM \$TABLE_NAME; -- Syntax error
+
+
+Access to lnav's environment variables is also available via the "environ"
+table. The table has two columns (name, value) and can be read and written
+to using SQL SELECT, INSERT, UPDATE, and DELETE statements. For example,
+to set the "FOO" variable to the value "BAR":
+
+ ;INSERT INTO environ SELECT 'FOO', 'BAR';
+
+As a more complex example, you can set the variable "LAST" to the last
+syslog line number by doing:
+
+ ;INSERT INTO environ SELECT 'LAST', (SELECT max(log_line) FROM syslog_log);
+
+A delete will unset the environment variable:
+
+ ;DELETE FROM environ WHERE name='LAST';
+
+The table allows you to easily use the results of a SQL query in lnav
+commands, which is especially useful when scripting lnav.
+
+
+PAPERTRAIL INTEGRATION
+======================
+
+Papertrail is a log management service with free and paid plans at:
+
+ http://papertrailapp.com
+
+To configure lnav to communicate with the papertrail service, you will
+need to set the PAPERTRAIL_API_TOKEN environment variable. You can
+get your API token from your user profile, available here:
+
+ https://papertrailapp.com/user/edit
+
+Searching papertrail using lnav can be done by prefixing the search terms
+with "pt:" and passing the value as a file name. For example, to search
+for log messages with the string 'Critical Error' when starting lnav you
+can do the following:
+
+ \$ setenv PAPERTRAIL_API_TOKEN xxxxxxxxx
+ \$ lnav "pt:'Critical Error'"
+
+If lnav is already started, you can use the ':open' command like so:
+
+ :open pt:'Critical Error'
+
+If you just want to tail your logs in papertrail, you can pass an empty
+search string (i.e. "pt:").
+
+Only one papertrail search can be active at a time. So, if an ':open'
+is done with a new query, the previous query will be closed first.

+
+K-Way Merge
+
+An implementation of "k-Way Merging" as described in "Fundamentals of Data Structures" by Horowitz/Sahni.
+
+The idea is to merge k sorted arrays limiting the number of comparisons. A tree is built containing the
+results of comparing the heads of each array. The top most node is always the smallest entry. Then, its
+corresponding leaf in the tree is refilled and the tree is processed again. It's easier to see in the
+following example:
+
+Imagine 4 sorted arrays:
+{5, 10, 15, 20}
+{10, 13, 16, 19}
+{2, 19, 26, 40}
+{18, 22, 23, 24}
+
+The initial tree looks like this:
+
+
+ 2
+ / \
+ 2 5
+ / \ / \
+ 18 2 10 5
+
+The '/' and '\' represent links. The bottom row has the leaves and they contain the heads of the arrays.
+The rows above the leaves represent the smaller of the two child nodes. Thus, the top node is the smallest.
+To process the next iteration, the top node gets popped and its leaf gets refilled. Then, the new leaf's
+associated nodes are processed. So, after the 2 is taken, it is filled with 19 (the next head of its array).
+After processing, the tree looks like this:
+
+
+ 5
+ / \
+ 18 5
+ / \ / \
+ 18 19 10 5
+
+So, you can see how the number of comparisons is reduced.
+
+A good use of this is when you have a very large array that needs to be sorted. Break it up into n small
+arrays and sort those. Then use this merge sort for the final sort. This can also be done with files. If
+you have n sorted files, you can merge them into one sorted file. K Way Merging works best when comparing
+is somewhat expensive.

+// SpookyHash: a 128-bit noncryptographic hash function
+// By Bob Jenkins, public domain
+// Oct 31 2010: alpha, framework + SpookyHash::Mix appears right
+// Oct 31 2011: alpha again, Mix only good to 2^^69 but rest appears right
+// Dec 31 2011: beta, improved Mix, tested it for 2-bit deltas
+// Feb 2 2012: production, same bits as beta
+// Feb 5 2012: adjusted definitions of uint* to be more portable
+// Mar 30 2012: 3 bytes/cycle, not 4. Alpha was 4 but wasn't thorough enough.
+// August 5 2012: SpookyV2 (different results)
+//
+// Up to 3 bytes/cycle for long messages. Reasonably fast for short messages.
+// All 1 or 2 bit deltas achieve avalanche within 1% bias per output bit.
+//
+// This was developed for and tested on 64-bit x86-compatible processors.
+// It assumes the processor is little-endian. There is a macro
+// controlling whether unaligned reads are allowed (by default they are).
+// This should be an equally good hash on big-endian machines, but it will
+// compute different results on them than on little-endian machines.
+//
+// Google's CityHash has similar specs to SpookyHash, and CityHash is faster
+// on new Intel boxes. MD4 and MD5 also have similar specs, but they are orders
+// of magnitude slower. CRCs are two or more times slower, but unlike
+// SpookyHash, they have nice math for combining the CRCs of pieces to form
+// the CRCs of wholes. There are also cryptographic hashes, but those are even
+// slower than MD5.

+# Tailer
+
+This directory contains the functionality for monitoring
+[remote files](https://docs.lnav.org/en/latest/usage.html#remote-files). The
+name "tailer" refers to the binary that is transferred to the remote host that
+takes care of tailing files and sending the contents back to the host that is
+running the main lnav binary. To ease integration with lnav's existing
+functionality, the remote files are mirrored locally. The tailer also
+supports interactive use by providing previews of file contents and
+TAB-completion possibilities.
+
+## Files
+
+The important files in this directory are:
+
+- [tailer.main.c](tailer.main.c) - The main() implementation for the tailer.
+- [tailer.looper.hh](tailer.looper.hh) - The service in the main lnav binary
+ that transfers tailers to hosts and communicates with them.
+- [tailer.h](tailer.h) and [tailerpp.hh](tailerpp.hh) - Utility libraries for
+ the tailer protocol.
+- tailer.ape - The [αcτµαlly pδrταblε εxεcµταblε](https://justine.lol/ape.html)
+ build of the tailer. This binary is produced by a GitHub Action and checked
+ in so the build process doesn't need to be supported on lots of platforms.
+
+## Flow
+
+When a remote-path is passed to lnav, the
+[file_collection.hh](../file_collection.hh) logic forwards the request to the
+`tailer::looper` service. This service makes two connections to the remote
+host using the `ssh` command so that the user's custom configurations will be
+used. The first connection is used to transfer the "tailer.ape" binary and
+make it executable. The second connection starts the tailer and uses
+stdin/stdout for a binary protocol and stderr for logging. The tailer then
+waits for requests to open files, preview files, and get possible paths for
+TAB-completions.

+// which uses the Boost Software License - Version 1.0
+// see here - https://github.com/catchorg/Catch2/blob/master/LICENSE.txt
+//
+// The concept of subcases (sections in Catch) and expression decomposition are from there.
+// Some parts of the code are taken directly:
+// - stringification - the detection of "ostream& operator<<(ostream&, const T&)" and StringMaker<>
+// - the Approx() helper class for floating point comparison
+// - colors in the console
+// - breaking into a debugger
+// - signal / SEH handling
+// - timer
+// - XmlWriter class - thanks to Phil Nash for allowing the direct reuse (AKA copy/paste)
+//
+// The expression decomposing templates are taken from lest - https://github.com/martinmoene/lest
+// which uses the Boost Software License - Version 1.0

+ ******************************************/
+
+/* We process inlines in few phases:
+ *
+ * (1) We go through the block text and collect all significant characters
+ * which may start/end a span or some other significant position into
+ * ctx->marks[]. Core of this is what md_collect_marks() does.
+ *
+ * We also do some very brief preliminary context-less analysis, whether
+ * it might be opener or closer (e.g. of an emphasis span).
+ *
+ * This speeds the other steps as we do not need to re-iterate over all
+ * characters anymore.
+ *
+ * (2) We analyze each potential mark types, in order by their precedence.
+ *
+ * In each md_analyze_XXX() function, we re-iterate list of the marks,
+ * skipping already resolved regions (in preceding precedences) and try to
+ * resolve them.
+ *
+ * (2.1) For trivial marks, which are single (e.g. HTML entity), we just mark
+ * them as resolved.
+ *
+ * (2.2) For range-type marks, we analyze whether the mark could be closer
+ * and, if yes, whether there is some preceding opener it could satisfy.
+ *
+ * If not we check whether it could be really an opener and if yes, we
+ * remember it so subsequent closers may resolve it.
+ *
+ * (3) Finally, when all marks were analyzed, we render the block contents
+ * by calling MD_RENDERER::text() callback, interrupting by ::enter_span()
+ * or ::close_span() whenever we reach a resolved mark.
+ */

+/* The mark structure.

+ * '`': Maybe code span start/end.
+ * '&': Maybe start of entity.

+ * '>': Maybe end of raw HTML or autolink.
+ * '[': Maybe start of link label or link text.
+ * '!': Equivalent of '[' for image.

+ * '@': Maybe permissive e-mail auto-link (needs MD_FLAG_PERMISSIVEEMAILAUTOLINKS).
+ * ':': Maybe permissive URL auto-link (needs MD_FLAG_PERMISSIVEURLAUTOLINKS).
+ * '.': Maybe permissive WWW auto-link (needs MD_FLAG_PERMISSIVEWWWAUTOLINKS).
+ * 'D': Dummy mark, it reserves a space for splitting a previous mark
+ * (e.g. emphasis) or to make more space for storing some special data
+ * related to the preceding mark (e.g. link).

+//
+// * info: Each Node in the map has a corresponding info byte, so there are 2^n info bytes.
+// Each byte is initialized to 0, meaning the corresponding Node is empty. Set to 1 means the
+// corresponding node contains data. Set to 2 means the corresponding Node is filled, but it
+// actually belongs to the previous position and was pushed out because that place is already

+//
+// * infoSentinel: Sentinel byte set to 1, so that iterator's ++ can stop at end() without the

+//
+// According to STL, order of templates has effect on throughput. That's why I've moved the
+// boolean to the front.

+ where such license applies only to those patent claims licensable
+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate
+ as of the date such litigation is filed.
+
+ 4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without
+ modifications, and in Source or Object form, provided that You
+ meet the following conditions:
+

+ Derivative Works a copy of this License; and
+
+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and
+
+ (c) You must retain, in the Source form of any Derivative Works

+ the Derivative Works; and
+
+ (d) If the Work includes a "NOTICE" text file as part of its
+ distribution, then any Derivative Works that You distribute must
+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+ * to determine whether we allowe the fixed point and scientific notation respectively.

+******************************************************************************
+**
+** This file implements a C-language subroutine that converts the content
+** of an SQLite database into UTF-8 text SQL statements that can be used
+** to exactly recreate the original database. ROWID values are preserved.
+**
+** A prototype of the implemented subroutine is this:
+**
+** int sqlite3_db_dump(
+** sqlite3 *db,
+** const char *zSchema,
+** const char *zTable,
+** void (*xCallback)(void*, const char*),
+** void *pArg
+** );
+**
+** The db parameter is the database connection. zSchema is the schema within
+** that database which is to be dumped. Usually the zSchema is "main" but
+** can also be "temp" or any ATTACH-ed database. If zTable is not NULL, then
+** only the content of that one table is dumped. If zTable is NULL, then all
+** tables are dumped.
+**
+** The generate text is passed to xCallback() in multiple calls. The second
+** argument to xCallback() is a copy of the pArg parameter. The first
+** argument is some of the output text that this routine generates. The
+** signature to xCallback() is designed to make it compatible with fputs().
+**
+** The sqlite3_db_dump() subroutine returns SQLITE_OK on success or some error
+** code if it encounters a problem.
+**
+** If this file is compiled with -DDBDUMP_STANDALONE then a "main()" routine
+** is included so that this routine becomes a command-line utility. The
+** command-line utility takes two or three arguments which are the name
+** of the database file, the schema, and optionally the table, forming the
+** first three arguments of a single call to the library routine.

+*************************************************************************
+**
+** This file demonstrates how to create a table-valued-function using
+** a virtual table. This demo implements the generate_series() function
+** which gives similar results to the eponymous function in PostgreSQL.
+** Examples:
+**
+** SELECT * FROM generate_series(0,100,5);
+**
+** The query above returns integers from 0 through 100 counting by steps
+** of 5.
+**
+** SELECT * FROM generate_series(0,100);
+**
+** Integers from 0 through 100 with a step size of 1.
+**
+** SELECT * FROM generate_series(20) LIMIT 10;
+**
+** Integers 20 through 29.
+**
+** HOW IT WORKS
+**
+** The generate_series "function" is really a virtual table with the
+** following schema:
+**
+** CREATE TABLE generate_series(
+** value,
+** start HIDDEN,
+** stop HIDDEN,
+** step HIDDEN
+** );
+**
+** Function arguments in queries against this virtual table are translated
+** into equality constraints against successive hidden columns. In other
+** words, the following pairs of queries are equivalent to each other:
+**
+** SELECT * FROM generate_series(0,100,5);
+** SELECT * FROM generate_series WHERE start=0 AND stop=100 AND step=5;
+**
+** SELECT * FROM generate_series(0,100);
+** SELECT * FROM generate_series WHERE start=0 AND stop=100;
+**
+** SELECT * FROM generate_series(20) LIMIT 10;
+** SELECT * FROM generate_series WHERE start=20 LIMIT 10;
+**
+** The generate_series virtual table implementation leaves the xCreate method
+** set to NULL. This means that it is not possible to do a CREATE VIRTUAL
+** TABLE command with "generate_series" as the USING argument. Instead, there
+** is a single generate_series virtual table that is always available without
+** having to be created first.
+**
+** The xBestIndex method looks for equality constraints against the hidden
+** start, stop, and step columns, and if present, it uses those constraints
+** to bound the sequence of generated values. If the equality constraints
+** are missing, it uses 0 for start, 4294967295 for stop, and 1 for step.
+** xBestIndex returns a small cost when both start and stop are available,
+** and a very large cost if either start or stop are unavailable. This
+** encourages the query planner to order joins such that the bounds of the
+** series are well-defined.

+/*!
+ * @mainpage xxHash
+ *
+ * xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed
+ * limits.
+ *
+ * It is proposed in four flavors, in three families:
+ * 1. @ref XXH32_family
+ * - Classic 32-bit hash function. Simple, compact, and runs on almost all
+ * 32-bit and 64-bit systems.
+ * 2. @ref XXH64_family
+ * - Classic 64-bit adaptation of XXH32. Just as simple, and runs well on most
+ * 64-bit systems (but _not_ 32-bit systems).
+ * 3. @ref XXH3_family
+ * - Modern 64-bit and 128-bit hash function family which features improved
+ * strength and performance across the board, especially on smaller data.
+ * It benefits greatly from SIMD and 64-bit without requiring it.
+ *
+ * Benchmarks
+ * ---
+ * The reference system uses an Intel i7-9700K CPU, and runs Ubuntu x64 20.04.
+ * The open source benchmark program is compiled with clang v10.0 using -O3 flag.

+ * @note

+ * - Hashes with an asterisk are cryptographic. Note that MD5 is non-cryptographic

+ * https://github.com/Cyan4973/xxHash/wiki
+ *
+ * Usage
+ * ------
+ * All xxHash variants use a similar API. Changing the algorithm is a trivial
+ * substitution.
+ *
+ * @pre
+ * For functions which take an input and length parameter, the following
+ * requirements are assumed:
+ * - The range from [`input`, `input + length`) is valid, readable memory.
+ * - The only exception is if the `length` is `0`, `input` may be `NULL`.
+ * - For C++, the objects must have the *TriviallyCopyable* property, as the
+ * functions access bytes directly as if it was an array of `unsigned char`.
+ *
+ * @anchor single_shot_example
+ * **Single Shot**
+ *
+ * These functions are stateless functions which hash a contiguous block of memory,
+ * immediately returning the result. They are the easiest and usually the fastest
+ * option.
+ *
+ * XXH32(), XXH64(), XXH3_64bits(), XXH3_128bits()
+ *
+ * @code{.c}
+ * #include <string.h>
+ * #include "xxhash.h"
+ *
+ * // Example for a function which hashes a null terminated string with XXH32().
+ * XXH32_hash_t hash_string(const char* string, XXH32_hash_t seed)
+ * {
+ * // NULL pointers are only valid if the length is zero
+ * size_t length = (string == NULL) ? 0 : strlen(string);
+ * return XXH32(string, length, seed);
+ * }
+ * @endcode
+ *
+ * @anchor streaming_example
+ * **Streaming**
+ *
+ * These groups of functions allow incremental hashing of unknown size, even
+ * more than what would fit in a size_t.
+ *

+ * - Improved speed for both small and large inputs
+ * - True 64-bit and 128-bit outputs
+ * - SIMD acceleration
+ * - Improved 32-bit viability
+ *
+ * Speed analysis methodology is explained here:
+ *
+ * https://fastcompression.blogspot.com/2019/03/presenting-xxh3.html
+ *
+ * Compared to XXH64, expect XXH3 to run approximately
+ * ~2x faster on large inputs and >3x faster on small ones,
+ * exact differences vary depending on platform.
+ *
+ * XXH3's speed benefits greatly from SIMD and 64-bit arithmetic,
+ * but does not require it.
+ * Most 32-bit and 64-bit targets that can run XXH32 smoothly can run XXH3
+ * at competitive speeds, even without vector support. Further details are
+ * explained in the implementation.
+ *
+ * Optimized implementations are provided for AVX512, AVX2, SSE2, NEON, POWER8,
+ * ZVector and scalar targets. This can be controlled via the @ref XXH_VECTOR
+ * macro. For the x86 family, an automatic dispatcher is included separately
+ * in @ref xxh_x86dispatch.c.
+ *
+ * XXH3 implementation is portable:
+ * it has a generic C90 formulation that can be compiled on any platform,
+ * all implementations generage exactly the same hash value on all platforms.
+ * Starting from v0.8.0, it's also labelled "stable", meaning that
+ * any future version will also generate the same hash value.
+ *
+ * XXH3 offers 2 variants, _64bits and _128bits.
+ *
+ * When only 64 bits are needed, prefer invoking the _64bits variant, as it
+ * reduces the amount of mixing, resulting in faster speed on small inputs.
+ * It's also generally simpler to manipulate a scalar return type than a struct.
+ *
+ * The API supports one-shot hashing, streaming mode, and custom secrets.

+ * once compared to four integers independently. Even when pmulld was
+ * fastest, Sandy/Ivy Bridge, it is still not worth it to go into SSE

+ *
+ * - Four instructions are required to rotate,
+ * movqda tmp, v // not required with VEX encoding
+ * pslld tmp, 13 // tmp <<= 13
+ * psrld v, 19 // x >>= 19
+ * por v, tmp // x |= tmp
+ * compared to one for scalar:
+ * roll v, 13 // reliably fast across the board
+ * shldl v, v, 13 // Sandy Bridge and later prefer this for some reason
+ *
+ * - Instruction level parallelism is actually more beneficial here because
+ * the SIMD actually serializes this operation: While v1 is rotating, v2
+ * can load data, while v3 can multiply. SSE forces them to operate
+ * together.
+ *

+/*
+ * One goal of XXH3 is to make it fast on both 32-bit and 64-bit, while
+ * remaining a true 64-bit/128-bit hash function.
+ *
+ * This is done by prioritizing a subset of 64-bit operations that can be
+ * emulated without too many steps on the average 32-bit machine.
+ *
+ * For example, these two lines seem similar, and run equally fast on 64-bit:
+ *
+ * xxh_u64 x;
+ * x ^= (x >> 47); // good
+ * x ^= (x >> 13); // bad
+ *
+ * However, to a 32-bit machine, there is a major difference.
+ *
+ * x ^= (x >> 47) looks like this:
+ *
+ * x.lo ^= (x.hi >> (47 - 32));
+ *
+ * while x ^= (x >> 13) looks like this:
+ *
+ * // note: funnel shifts are not usually cheap.
+ * x.lo ^= (x.lo >> 13) | (x.hi << (32 - 13));
+ * x.hi ^= (x.hi >> 13);
+ *
+ * The first one is significantly faster than the second, simply because the
+ * shift is larger than 32. This means:
+ * - All the bits we need are in the upper 32 bits, so we can ignore the lower
+ * 32 bits in the shift.
+ * - The shift result will always fit in the lower 32 bits, and therefore,
+ * we can ignore the upper 32 bits in the xor.
+ *
+ * Thanks to this optimization, XXH3 only requires these features to be efficient:
+ *
+ * - Usable unaligned access
+ * - A 32-bit or 64-bit ALU
+ * - If 32-bit, a decent ADC instruction
+ * - A 32 or 64-bit multiply with a 64-bit result
+ * - For the 128-bit variant, a decent byteswap helps short inputs.
+ *
+ * The first two are already required by XXH32, and almost all 32-bit and 64-bit
+ * platforms which can run XXH32 can run XXH3 efficiently.
+ *
+ * Thumb-1, the classic 16-bit only subset of ARM's instruction set, is one
+ * notable exception.
+ *
+ * First of all, Thumb-1 lacks support for the UMULL instruction which
+ * performs the important long multiply. This means numerous __aeabi_lmul
+ * calls.
+ *
+ * Second of all, the 8 functional registers are just not enough.
+ * Setup for __aeabi_lmul, byteshift loads, pointers, and all arithmetic need
+ * Lo registers, and this shuffling results in thousands more MOVs than A32.
+ *
+ * A32 and T32 don't have this limitation. They can access all 14 registers,
+ * do a 32->64 multiply with UMULL, and the flexible operand allowing free
+ * shifts is helpful, too.
+ *
+ * Therefore, we do a quick sanity check.
+ *
+ * If compiling Thumb-1 for a target which supports ARM instructions, we will
+ * emit a warning, as it is not a "sane" platform to compile for.
+ *
+ * Usually, if this happens, it is because of an accident and you probably need
+ * to specify -march, as you likely meant to compile for a newer architecture.

+ *
+ * While PMULUDQ and VMULEUW both perform a mask, VMLAL.U32 performs an upcast.
+ *
+ * To do the same operation, the 128-bit 'Q' register needs to be split into
+ * two 64-bit 'D' registers, performing this operation::
+ *
+ * [ a | b ]
+ * | '---------. .--------' |
+ * | x |
+ * | .---------' '--------. |
+ * [ a & 0xFFFFFFFF | b & 0xFFFFFFFF ],[ a >> 32 | b >> 32 ]
+ *
+ * Due to significant changes in aarch64, the fastest method for aarch64 is
+ * completely different than the fastest method for ARMv7-A.
+ *
+ * ARMv7-A treats D registers as unions overlaying Q registers, so modifying
+ * D11 will modify the high half of Q5. This is similar to how modifying AH
+ * will only affect bits 8-15 of AX on x86.
+ *
+ * VZIP takes two registers, and puts even lanes in one register and odd lanes
+ * in the other.
+ *
+ * On ARMv7-A, this strangely modifies both parameters in place instead of
+ * taking the usual 3-operand form.
+ *
+ * Therefore, if we want to do this, we can simply use a D-form VZIP.32 on the
+ * lower and upper halves of the Q register to end up with the high and low
+ * halves where we want - all in one instruction.
+ *
+ * vzip.32 d10, d11 @ d10 = { d10[0], d11[0] }; d11 = { d10[1], d11[1] }
+ *
+ * Unfortunately we need inline assembly for this: Instructions modifying two
+ * registers at once is not possible in GCC or Clang's IR, and they have to
+ * create a copy.
+ *
+ * aarch64 requires a different approach.
+ *
+ * In order to make it easier to write a decent compiler for aarch64, many
+ * quirks were removed, such as conditional execution.
+ *
+ * NEON was also affected by this.
+ *
+ * aarch64 cannot access the high bits of a Q-form register, and writes to a
+ * D-form register zero the high bits, similar to how writes to W-form scalar
+ * registers (or DWORD registers on x86_64) work.
+ *
+ * The formerly free vget_high intrinsics now require a vext (with a few
+ * exceptions)
+ *
+ * Additionally, VZIP was replaced by ZIP1 and ZIP2, which are the equivalent
+ * of PUNPCKL* and PUNPCKH* in SSE, respectively, in order to only modify one
+ * operand.
+ *
+ * The equivalent of the VZIP.32 on the lower and upper halves would be this
+ * mess:
+ *
+ * ext v2.4s, v0.4s, v0.4s, #2 // v2 = { v0[2], v0[3], v0[0], v0[1] }
+ * zip1 v1.2s, v0.2s, v2.2s // v1 = { v0[0], v2[0] }
+ * zip2 v0.2s, v0.2s, v1.2s // v0 = { v0[1], v2[1] }
+ *
+ * Instead, we use a literal downcast, vmovn_u64 (XTN), and vshrn_n_u64 (SHRN):
+ *
+ * shrn v1.2s, v0.2d, #32 // v1 = (uint32x2_t)(v0 >> 32);
+ * xtn v0.2s, v0.2d // v0 = (uint32x2_t)(v0 & 0xFFFFFFFF);

+ * @ingroup tuning

+ *
+ * On AArch64 when not optimizing for size, XXH3 will run 6 lanes using NEON and

+ *
+ * This can be set to 2, 4, 6, or 8. ARMv7 will default to all 8 NEON lanes, as the
+ * emulated 64-bit arithmetic is too slow.
+ *
+ * Modern ARM CPUs are _very_ sensitive to how their pipelines are used.
+ *
+ * For example, the Cortex-A73 can dispatch 3 micro-ops per cycle, but it can't
+ * have more than 2 NEON (F0/F1) micro-ops. If you are only using NEON instructions,
+ * you are only using 2/3 of the CPU bandwidth.
+ *
+ * This is even more noticable on the more advanced cores like the A76 which
+ * can dispatch 8 micro-ops per cycle, but still only 2 NEON micro-ops at once.
+ *
+ * Therefore, @ref XXH3_NEON_LANES lanes will be processed using NEON, and the
+ * remaining lanes will use scalar instructions. This improves the bandwidth
+ * and also gives the integer pipelines something to do besides twiddling loop
+ * counters and pointers.

+ * class will fork off a child process that sends and receives VT52 keycodes(?)
+ * which is translated by this class into curses calls.
+ *
+ * VT52 seems to be the simplest terminal to emulate since we do not need to
+ * maintain the state of the screen, beyond past lines. For example, when
+ * inserting a character, VT52 moves the cursor to the insertion point, clears
+ * the rest of the line and then rewrites the rest of the line with the new
+ * character. This is in contrast to VT100 which moves the cursor to the
+ * insertion point and then sends a code to insert the character and relying
+ * on the terminal to shift the rest of the line to the right a character.

+ * bits of a chunk of JSON before the last bits are available (still on
+ * the network or disk). This makes the lexer more complex. The
+ * responsibility of the lexer is to handle transparently the case where
+ * a chunk boundary falls in the middle of a token. This is
+ * accomplished is via a buffer and a character reading abstraction.
+ *
+ * Overview of implementation
+ *
+ * When we lex to end of input string before end of token is hit, we
+ * copy all of the input text composing the token into our lexBuf.
+ *
+ * Every time we read a character, we do so through the readChar function.
+ * readChar's responsibility is to handle pulling all chars from the buffer
+ * before pulling chars from input text

+
+lnav
+
+A fancy log file viewer for the terminal.
+
+Overview
+
+The Logfile Navigator, lnav, is an enhanced log file viewer that takes
+advantage of any semantic information that can be gleaned from the
+files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+
+Opening Paths/URLs
+
+The main arguments to lnav are the local/remote files, directories,
+glob patterns, or URLs to be viewed. If no arguments are given, the
+default syslog file for your system will be opened. These arguments
+will be polled periodically so that any new data or files will be
+automatically loaded. If a previously loaded file is removed or
+replaced, it will be closed and the replacement opened.
+
+Note: When opening SFTP URLs, if the password is not provided for the
+host, the SSH agent can be used to do authentication.
+
+Options
+
+Lnav takes a list of files to view and/or you can use the flag
+arguments to load well-known log files, such as the syslog log files.
+The flag arguments are:
+
+ •  -a  Load all of the most recent log file types.
+ •  -r  Recursively load files from the given directory
+ hierarchies.
+ •  -R  Load older rotated log files as well.
+
+When using the flag arguments, lnav will look for the files relative
+to the current directory and its parent directories. In other words,
+if you are working within a directory that has the well-known log
+files, those will be preferred over any others.
+
+If you do not want the default syslog file to be loaded when no files
+are specified, you can pass the  -N  flag.
+
+Any files given on the command-line are scanned to determine their log
+file format and to create an index for each line in the file. You do
+not have to manually specify the log file format. The currently
+supported formats are: syslog, apache, strace, tcsh history, and
+generic log files with timestamps.
+
+Lnav will also display data piped in on the standard input. The
+following options are available when doing so:
+
+ •  -t  Prepend timestamps to the lines of data being read
+ in on the standard input.
+ •  -w file  Write the contents of the standard input to
+ this file.
+
+To automatically execute queries or lnav commands after the files have
+been loaded, you can use the following options:
+
+ •  -c cmd  A command, query, or file to execute. The
+ first character determines the type of operation: a colon
+ ( : ) is used for the built-in commands; a semi-colon ( ;
+ ) for SQL queries; and a pipe symbol ( | ) for executing
+ a file containing other commands. For example, to open
+ the file "foo.log" and go to the tenth line in the file,
+ you can do:
+
+ ▌lnav -c ':goto 10' foo.log 
+
+ This option can be given multiple times to execute
+ multiple operations in sequence.
+ •  -f file  A file that contains commands, queries, or
+ files to execute. This option is a shortcut for  -c '|file'
+ . You can use a dash ( - ) to execute commands from the
+ standard input.
+
+To execute commands/queries without opening the interactive text UI,
+you can pass the  -n  option. This combination of options allows you
+to write scripts for processing logs with lnav. For example, to get a
+list of IP addresses that dhclient has bound to in CSV format:
+
+ ▌#! /usr/bin/lnav -nf 
+ ▌ 
+ ▌# Usage: dhcp_ip.lnav /var/log/messages 
+ ▌# Only include lines that look like: 
+ ▌# Apr 29 00:31:56 example-centos5 dhclient: bound to 10.1.10.103 -- renewal in 9938 seconds. 
+ ▌ 
+ ▌:filter-in dhclient: bound to 
+ ▌ 
+ ▌# The log message parser will extract the IP address 
+ ▌# as col_0, so we select that and alias it to "dhcp_ip". 
+ ▌;SELECT DISTINCT col_0 AS dhcp_ip FROM logline; 
+ ▌ 
+ ▌# Finally, write the results of the query to stdout. 
+ ▌:write-csv-to - 
+
+Display
+
+The main part of the display shows the log lines from the files
+interleaved based on time-of-day. New lines are automatically loaded
+as they are appended to the files and, if you are viewing the bottom
+of the files, lnav will scroll down to display the new lines, much
+like  tail -f .
+
+On color displays, the lines will be highlighted as follows:
+
+ • Errors will be colored in red;
+ • warnings will be yellow;
+ • boundaries between days will be underlined; and
+ • various color highlights will be applied to: IP
+ addresses, SQL keywords, XML tags, file and line numbers
+ in Java backtraces, and quoted strings.
+
+To give you an idea of where you are spatially, the right side of the
+display has a proportionally sized 'scroll bar' that indicates your
+current position in the files. The scroll bar will also show areas of
+the file where warnings or errors are detected by coloring the bar
+yellow or red, respectively. Tick marks will also be added to the left
+and right-hand side of the bar, for search hits and bookmarks.
+
+The bar on the left side indicates the file the log message is from. A
+break in the bar means that the next log message comes from a
+different file. The color of the bar is derived from the file name.
+Pressing the left-arrow or  h  will reveal the source file names for
+each message and pressing again will show the full paths.
+
+Above and below the main body are status lines that display a variety
+of information. The top line displays:
+
+ • The current time, configurable by the  /ui/clock-format 
+ property.
+ • The highest priority message from the  lnav_user_notifications 
+ table. You can insert rows into this table to display
+ your own status messages. The default message displayed
+ on startup explains how to focus on the next status line
+ at the top, which is an interactive breadcrumb bar.
+
+The second status line at the top display breadcrumbs for the top line
+in the main view. Pressing  ENTER  will focus input on the breadcrumb
+bar, the cursor keys can be used to select a breadcrumb. The common
+breadcrumbs are:
+
+ • The name of the current view.
+ • In the log view, the timestamp of the top log message.
+ • In the log view, the format of the log file the top log
+ message is from.
+ • The name of the file the top line was pulled from.
+ • If the top line is within a larger chunk of structured
+ data, the path to the value in the top line will be
+ shown.
+
+Notes:
+
+ 1. Pressing  CTRL-A / CTRL-E  will select the first/last
+ breadcrumb.
+ 2. Typing text while a breadcrumb is selected will
+ perform a fuzzy search on the possibilities.
+
+The bottom status bar displays:
+
+ • The line number for the top line in the display.
+ • The current search hit, the total number of hits, and
+ the search term.
+
+If the view supports filtering, there will be a status line showing
+the following:
+
+ • The number of enabled filters and the total number of
+ filters.
+ • The number of lines not displayed because of filtering.
+
+To edit the filters, you can press TAB to change the focus from the
+main view to the filter editor. The editor allows you to create,
+enable/disable, and delete filters easily.
+
+Along with filters, a "Files" panel will also be available for viewing
+and controlling the files that lnav is currently monitoring.
+
+Finally, the last line on the display is where you can enter search
+patterns and execute internal commands, such as converting a
+unix-timestamp into a human-readable date. The command-line is
+implemented using the readline library, so the usual set of keyboard
+shortcuts are available. Most commands and searches also support
+tab-completion.
+
+The body of the display is also used to display other content, such
+as: the help file, histograms of the log messages over time, and SQL
+results. The views are organized into a stack so that any time you
+activate a new view with a key press or command, the new view is
+pushed onto the stack. Pressing the same key again will pop the view
+off of the stack and return you to the previous view. Note that you
+can always use  q  to pop the top view off of the stack.
+
+Default Key Bindings

+Views
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ ? View/leave this help message.
+ q Leave the current view or quit the program when in
+ the log file view.
+ Q Similar to  q , except it will try to sync the top
+ time between the current and former views. For
+ example, when leaving the spectrogram view with  Q
+ , the top time in that view will be matched to the
+ top time in the log view.
+ TAB Toggle focusing on the filter editor or the main
+ view.
+ ENTER Focus on the breadcrumb bar.
+ a/A Restore the view that was previously popped with  q
+ / Q . The  A  hotkey will try to match the top
+ times between the two views.
+ X Close the current text file or log file.
+
+Spatial Navigation
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════════
+ g/Home Move to the top of the file.
+ G/End Move to the end of the file. If the view is
+ already at the end, it will move to the last line.
+ SPACE/PgDn Move down a page.
+ b/PgUp Move up a page.
+ j/↓ Move down a line.
+ k/↑ Move up a line.
+ h/← Move to the left. In the log view, moving left
+ will reveal the source log file names for each
+ line. Pressing again will reveal the full path.
+ l/→ Move to the right.
+ H/Shift ← Move to the left by a smaller increment.
+ L/Shift → Move to the right by a smaller increment.
+ e/E Move to the next/previous error.
+ w/W Move to the next/previous warning.
+ n/N Move to the next/previous search hit. When pressed
+ repeatedly within a short time, the view will move
+ at least a full page at a time instead of moving
+ to the next hit.
+ f/F Move to the next/previous file. In the log view,
+ this moves to the next line from a different file.
+ In the text view, this rotates the view to the
+ next file.
+ >/< Move horizontally to the next/previous search hit.
+ o/O Move forward/backward to the log message with a
+ matching 'operation ID' (opid) field.
+ u/U Move forward/backward through any user bookmarks
+ you have added using the 'm' key. This hotkey will
+ also jump to the start of any log partitions that
+ have been created with the 'partition-name'
+ command.
+ s/S Move to the next/previous "slow down" in the log
+ message rate. A slow down is detected by measuring
+ how quickly the message rate has changed over the
+ previous several messages. For example, if one
+ message is logged every second for five seconds
+ and then the last message arrives five seconds
+ later, the last message will be highlighted as a
+ slow down.
+ {/} Move to the previous/next location in history.
+ Whenever you jump to a new location in the view,
+ the location will be added to the history. The
+ history is not updated when using only the arrow
+ keys.
+
+Chronological Navigation
+
+ Key(s) Action
+══════════════════════════════════════════════════════════════════
+ d/D Move forward/backward 24 hours from the current
+ position in the log file.
+ 1-6/Shift 1-6 Move to the next/previous n'th ten minute of the
+ hour. For example, '4' would move to the first log
+ line in the fortieth minute of the current hour in
+ the log. And, '6' would move to the next hour
+ boundary.
+ 7/8 Move to the previous/next minute.
+ 0/Shift 0 Move to the next/previous day boundary.
+ r/R Move forward/backward based on the relative time
+ that was last used with the 'goto' command. For
+ example, executing ':goto a minute later' will
+ move the log view forward a minute and then
+ pressing 'r' will move it forward a minute again.
+ Pressing 'R' will then move the view in the
+ opposite direction, so backwards a minute.
+
+Bookmarks
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ m Mark/unmark the line at the top of the display.
+ The line will be highlighted with reverse video to
+ indicate that it is a user bookmark. You can use
+ the  u  hotkey to iterate through marks you have
+ added.
+ M Mark/unmark all the lines between the top of the
+ display and the last line marked/unmarked.
+ J Mark/unmark the next line after the previously
+ marked line.
+ K Like  J  except it toggles the mark on the
+ previous line.
+ c Copy the marked text to the X11 selection buffer
+ or OS X clipboard.
+ C Clear all marked lines.
+
+Display options
+
+ Key(s) Action
+══════════════════════════════════════════════════════════════════
+ P Switch to/from the pretty-printed view of the log
+ or text files currently displayed. In this view,
+ structured data, such as XML, will be reformatted
+ to make it easier to read.
+ t Switch to/from the text file view. The text file
+ view is for any files that are not recognized as
+ log files.
+ = Pause/unpause loading of new file data.
+ Ctrl-L (Lo-fi mode) Exit screen-mode and write the
+ displayed log lines in plain text to the terminal
+ until a key is pressed. Useful for copying long
+ lines from the terminal without picking up any of
+ the extra decorations.
+ T Toggle the display of the "elapsed time" column
+ that shows the time elapsed since the beginning of
+ the logs or the offset from the previous bookmark.
+ Sharp changes in the message rate are highlighted
+ by coloring the separator between the time column
+ and the log message. A red highlight means the
+ message rate has slowed down and green means it
+ has sped up. You can use the "s/S" hotkeys to scan
+ through the slow downs.
+ i View/leave a histogram of the log messages over
+ time. The histogram counts the number of displayed
+ log lines for each bucket of time. The bars are
+ layed out horizontally with colored segments
+ representing the different log levels. You can use
+ the  z  hotkey to change the size of the time
+ buckets (e.g. ten minutes, one hour, one day).
+ I Switch between the log and histogram views while
+ keeping the time displayed at the top of each view
+ in sync. For example, if the top line in the log
+ view is "11:40", hitting  I  will switch to the
+ histogram view and scrolled to display "11:00" at
+ the top (if the zoom level is hours).
+ z/Shift Z Zoom in or out one step in the histogram view.
+ v Switch to/from the SQL result view.
+ V Switch between the log and SQL result views while
+ keeping the top line number in the log view in
+ sync with the log_line column in the SQL view. For
+ example, doing a query that selects for
+ "log_idle_msecs" and "log_line", you can move the
+ top of the SQL view to a line and hit 'V' to
+ switch to the log view and move to the line number
+ that was selected in the "log_line" column. If
+ there is no "log_line" column, lnav will find the
+ first column with a timestamp and move to
+ corresponding time in the log view.
+ TAB/Shift TAB In the SQL result view, cycle through the columns
+ that are graphed. Initially, all number values are
+ displayed in a stacked graph. Pressing TAB will
+ change the display to only graph the first column.
+ Repeatedly pressing TAB will cycle through the
+ columns until they are all graphed again.
+ p In the log view: enable or disable the display of
+ the fields that the log message parser knows about
+ or has discovered. This overlay is temporarily
+ enabled when the semicolon key (;) is pressed so
+ that it is easier to write queries.
+ In the DB view: enable or disable the display of
+ values in columns containing JSON-encoded values
+ in the top row. The overlay will display the
+ JSON-Pointer reference and value for all fields in
+ the JSON data.
+ CTRL-W Toggle word-wrapping.
+ CTRL-P Show/hide the data preview panel that may be
+ opened when entering commands or SQL queries.
+ CTRL-F Toggle the enabled/disabled state of all filters
+ in the current view.
+ x Toggle the hiding of log message fields. The
+ hidden fields will be replaced with three bullets
+ and highlighted in yellow.
+ F2 Toggle mouse support.
+
+Query
+
+ Key(s) Action
+════════════════════════════════════════════════════════════════════════
+ /regexp Start a search for the given regular expression.
+ The search is live, so when there is a pause in
+ typing, the currently running search will be
+ canceled and a new one started. The first ten
+ lines that match the search will be displayed in
+ the preview window at the bottom of the view.
+ History is maintained for your searches so you can
+ rerun them easily. Words that are currently
+ displayed are also available for tab-completion,
+ so you can easily search for values without
+ needing to copy-and-paste the string. If there is
+ an error encountered while trying to interpret the
+ expression, the error will be displayed in red on
+ the status line. While the search is active, the
+ 'hits' field in the status line will be green,
+ when finished it will turn back to black.
+ :<command> Execute an internal command. The commands are
+ listed below. History is also supported in this
+ context as well as tab-completion for commands and
+ some arguments. The result of the command replaces
+ the command you typed.
+ ;<sql> Execute an SQL query. Most supported log file
+ formats provide a sqlite virtual table backend
+ that can be used in queries. See the SQL section
+ below for more information.
+ |<script> [arg1...] Execute an lnav script contained in a format
+ directory (e.g. ~/.lnav/formats/default). The
+ script can contain lines starting with  : ,  ; ,
+ or  |  to execute commands, SQL queries or execute
+ other files in lnav. Any values after the script
+ name are treated as arguments can be referenced in
+ the script using  $1 ,  $2 , and so on, like in a
+ shell script.
+ CTRL+], ESCAPE Abort command-line entry started with  / ,  : ,  ;
+ , or  | .
+
+ ▌Note: The regular expression format used by lnav is PCRE[1]
+ ▌(Perl-Compatible Regular Expressions).
+ ▌
+ ▌ ▌[1] - http://perldoc.perl.org/perlre.html
+ ▌
+ ▌If the search string is not valid PCRE, a search is done for
+ ▌the exact string instead of doing a regex search.
+
+Session
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ CTRL-R Reset the session state. This will save the
+ current session state (filters, highlights) and
+ then reset the state to the factory default.
+
+Filter Editor
+
+The following hotkeys are only available when the focus is on the
+filter editor. You can change the focus by pressing TAB.
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ q Switch the focus back to the main view.
+ j/↓ Select the next filter.
+ k/↑ Select the previous filter.
+ o Create a new "out" filter.
+ i Create a new "in" filter .
+ SPACE Toggle the enabled/disabled state of the currently
+ selected filter.
+ t Toggle the type of filter between "in" and "out".
+ ENTER Edit the selected filter.
+ D Delete the selected filter.
+
+Mouse Support (experimental)
+
+If you are using Xterm, or a compatible terminal, you can use the
+mouse to mark lines of text and move the view by grabbing the
+scrollbar.
+
+NOTE: You need to manually enable this feature by setting the LNAV_EXP
+environment variable to "mouse". F2 toggles mouse support.
+
+SQL Queries (experimental)
+
+Lnav has support for performing SQL queries on log files using the
+Sqlite3 "virtual" table feature. For all supported log file types,
+lnav will create tables that can be queried using the subset of SQL
+that is supported by Sqlite3. For example, to get the top ten URLs
+being accessed in any loaded Apache log files, you can execute:
+
+ ▌;SELECT cs_uri_stem, count(*) AS total FROM access_log 
+ ▌ GROUP BY cs_uri_stem ORDER BY total DESC LIMIT 10; 
+
+The query result view shows the results and graphs any numeric values
+found in the result, much like the histogram view.
+
+The builtin set of log tables are listed below. Note that only the log
+messages that match a particular format can be queried by a particular
+table. You can find the file format and table name for the top log
+message by looking in the upper right hand corner of the log file
+view.
+
+Some commonly used format tables are:
+
+ Name Description
+════════════════════════════════════════════════════════════════
+ access_log Apache common access log format
+ syslog_log Syslog format
+ strace_log Strace log format
+ generic_log 'Generic' log format. This table contains messages
+ from files that have a very simple format with a
+ leading timestamp followed by the message.
+
+NOTE: You can get a dump of the schema for the internal tables, and
+any attached databases, by running the  .schema  SQL command.
+
+The columns available for the top log line in the view will
+automatically be displayed after pressing the semicolon ( ; ) key. All
+log tables contain at least the following columns:
+
+ Column Description
+═══════════════════════════════════════════════════════════════════
+ log_line The line number in the file, starting at zero.
+ log_part The name of the partition. You can change this
+ column using an UPDATE SQL statement or with the
+ 'partition-name' command. After a value is set,
+ the following log messages will have the same
+ partition name up until another name is set.
+ log_time The time of the log entry.
+ log_idle_msecs The amount of time, in milliseconds, between the
+ current log message and the previous one.
+ log_level The log level (e.g. info, error, etc...).
+ log_mark The bookmark status for the line. This column can
+ be written to using an UPDATE query.
+ log_path The full path to the file.
+ log_text The raw line of text. Note that this column is
+ not included in the result of a 'select *', but it
+ does exist.
+
+The following tables include the basic columns as listed above and
+include a few more columns since the log file format is more
+structured.
+
+ •  syslog_log 
+
+ Column Description
+ ═════════════════════════════════════════════════════════════════
+ log_hostname The hostname the message was received from.
+ log_procname The name of the process that sent the message.

+
+These tables are created dynamically and not stored in memory or on
+disk. If you would like to persist some information from the tables,
+you can attach another database and create tables in that database.
+For example, if you wanted to save the results from the earlier
+example of a top ten query into the "/tmp/topten.db" file, you can do:
+
+ ▌;ATTACH DATABASE '/tmp/topten.db' AS topten; 
+ ▌;CREATE TABLE topten.foo AS SELECT cs_uri_stem, count(*) AS total 
+ ▌ FROM access_log GROUP BY cs_uri_stem ORDER BY total DESC 
+ ▌ LIMIT 10; 
+
+Dynamic logline Table (experimental)
+
+(NOTE: This feature is still very new and not completely reliable yet,
+use with care.)
+
+For log formats that lack message structure, lnav can parse the log
+message and attempt to extract any data fields that it finds. This
+feature is available through the  logline  log table. This table is
+dynamically created and defined based on the message at the top of the
+log view. For example, given the following log message from "sudo",
+lnav will create the "logline" table with columns for "TTY", "PWD",
+"USER", and "COMMAND":
+
+ ▌May 24 06:48:38 Tim-Stacks-iMac.local sudo[76387]: stack : TTY=ttys003 ; PWD=/Users/stack/github/lbuild ; USER=root ; COMMAND=/bin/echo Hello, World! 
+
+Queries executed against this table will then only return results for
+other log messages that have the same format. So, if you were to
+execute the following query while viewing the above line, you might
+get the following results:
+
+ ▌;SELECT USER,COMMAND FROM logline; 
+
+ USER COMMAND
+═════════════════════════════════
+ root /bin/echo Hello, World!
+ mal /bin/echo Goodbye, World!
+
+The log parser works by examining each message for key/value pairs
+separated by an equal sign (=) or a colon (:). For example, in the
+previous example of a "sudo" message, the parser sees the "USER=root"
+string as a pair where the key is "USER" and the value is "root". If
+no pairs can be found, then anything that looks like a value is
+extracted and assigned a numbered column. For example, the following
+line is from "dhcpd":
+
+ ▌Sep 16 22:35:57 drill dhcpd: DHCPDISCOVER from 00:16:ce:54:4e:f3 via hme3 
+
+In this case, the lnav parser recognizes that "DHCPDISCOVER", the MAC
+address and the "hme3" device name are values and not normal words.
+So, it builds a table with three columns for each of these values. The
+regular words in the message, like "from" and "via", are then used to
+find other messages with a similar format.
+
+If you would like to execute queries against log messages of different
+formats at the same time, you can use the 'create-logline-table'
+command to permanently create a table using the top line of the log
+view as a template.
+
+Other SQL Features
+
+Environment variables can be used in SQL statements by prefixing the
+variable name with a dollar-sign ($). For example, to read the value
+of the  HOME  variable, you can do:
+
+ ▌;SELECT $HOME; 
+
+To select the syslog messages that have a hostname field that is equal
+to the  HOSTNAME  variable:
+
+ ▌;SELECT * FROM syslog_log WHERE log_hostname = $HOSTNAME; 
+
+NOTE: Variable substitution is done for fields in the query and is not
+a plain text substitution. For example, the following statement WILL
+NOT WORK:
+
+ ▌;SELECT * FROM $TABLE_NAME; -- Syntax error 
+
+Access to lnav's environment variables is also available via the
+"environ" table. The table has two columns (name, value) and can be
+read and written to using SQL SELECT, INSERT, UPDATE, and DELETE
+statements. For example, to set the "FOO" variable to the value "BAR":
+
+ ▌;INSERT INTO environ SELECT 'FOO', 'BAR'; 
+
+As a more complex example, you can set the variable "LAST" to the last
+syslog line number by doing:
+
+ ▌;INSERT INTO environ SELECT 'LAST', (SELECT max(log_line) FROM syslog_log); 
+
+A delete will unset the environment variable:
+
+ ▌;DELETE FROM environ WHERE name='LAST'; 
+
+The table allows you to easily use the results of a SQL query in lnav
+commands, which is especially useful when scripting lnav.

+
+LNAV – The Logfile Navigator
+
+The Log File Navigator, lnav for short, is an advanced log file viewer
+for the small-scale. It is a terminal application that can understand
+your log files and make it easy for you to find problems with little
+to no setup.
+
+Screenshot
+
+The following screenshot shows a syslog file. Log lines are displayed
+with highlights. Errors are red and warnings are yellow.

+
+Features
+
+ • Log messages from different files are collated together
+ into a single view
+ • Automatic detection of log format
+ • Automatic decompression of GZip and BZip2 files
+ • Filter log messages based on regular expressions
+ • Use SQL to analyze your logs
+ • And more...
+
+Installation
+
+Download a statically-linked binary for Linux/MacOS from the release
+page[1]
+
+ ▌[1] - https://github.com/tstack/lnav/releases/latest#release-artifacts
+
+Usage
+
+The only file installed is the executable,  lnav . You can execute it
+with no arguments to view the default set of files:
+
+ ▌$ lnav 
+
+You can view all the syslog messages by running:
+
+ ▌$ lnav /var/log/messages* 
+
+Usage with  systemd-journald 
+
+On systems running  systemd-journald , you can use  lnav  as the
+pager:
+
+ ▌$ journalctl | lnav 
+
+or in follow mode:
+
+ ▌$ journalctl -f | lnav 
+
+Since  journalctl 's default output format omits the year, if you are
+viewing logs which span multiple years you will need to change the
+output format to include the year, otherwise  lnav  gets confused:
+
+ ▌$ journalctl -o short-iso | lnav 
+
+It is also possible to use  journalctl 's json output format and  lnav
+will make use of additional fields such as PRIORITY and _SYSTEMD_UNIT:
+
+ ▌$ journalctl -o json | lnav 
+
+In case some MESSAGE fields contain special characters such as ANSI
+color codes which are considered as unprintable by journalctl,
+specifying  journalctl 's  -a  option might be preferable in order to
+output those messages still in a non-binary representation:
+
+ ▌$ journalctl -a -o json | lnav 
+
+If using systemd v236 or newer, the output fields can be limited to
+the ones actually recognized by  lnav  for increased efficiency:
+
+ ▌$ journalctl -o json --output-fields=MESSAGE,PRIORITY,_PID,SYSLOG_IDENTIFIER,_SYSTEMD_UNIT | lnav 
+
+If your system has been running for a long time, for increased
+efficiency you may want to limit the number of log lines fed into  lnav
+, e.g. via  journalctl 's  -n  or  --since=...  options.
+
+In case of a persistent journal, you may want to limit the number of
+log lines fed into  lnav  via  journalctl 's  -b  option.

+Building From Source
+
+Prerequisites
+
+The following software packages are required to build lnav:
+
+ • gcc/clang - A C++14-compatible compiler.
+ • libpcre2 - The Perl Compatible Regular Expression v2
+ (PCRE2) library.
+ • sqlite - The SQLite database engine. Version 3.9.0
+ or higher is required.
+ • ncurses - The ncurses text UI library.
+ • readline - The readline line editing library.
+ • zlib - The zlib compression library.
+ • bz2 - The bzip2 compression library.
+ • libcurl - The cURL library for downloading files
+ from URLs. Version 7.23.0 or higher is required.
+ • libarchive - The libarchive library for opening archive
+ files, like zip/tgz.
+ • wireshark - The 'tshark' program is used to interpret
+ pcap files.
+
+Build
+
+Lnav follows the usual GNU style for configuring and installing
+software:
+
+Run  ./autogen.sh  if compiling from a cloned repository.
+
+ ▌$ ./configure 
+ ▌$ make 
+ ▌$ sudo make install 
+
+See Also
+
+Angle-grinder[1] is a tool to slice and dice log files on the
+command-line. If you're familiar with the SumoLogic query language,
+you might find this tool more comfortable to work with.

+✘ error: unable to parse markdown file
+ reason: file has invalid UTF-8 at offset 4461: Expecting bytes in the following ranges: 00..7F C2..F4.
+
+UTF-8 decoder capability and stress test
+----------------------------------------
+
+Markus Kuhn <http://www.cl.cam.ac.uk/~mgk25/> - 2015-08-28 - CC BY 4.0
+
+This test file can help you examine, how your UTF-8 decoder handles
+various types of correct, malformed, or otherwise interesting UTF-8
+sequences. This file is not meant to be a conformance test. It does
+not prescribe any particular outcome. Therefore, there is no way to
+"pass" or "fail" this test file, even though the text does suggest a
+preferable decoder behaviour at some places. Its aim is, instead, to
+help you think about, and test, the behaviour of your UTF-8 decoder on a
+systematic collection of unusual inputs. Experience so far suggests
+that most first-time authors of UTF-8 decoders find at least one
+serious problem in their decoder using this file.
+
+The test lines below cover boundary conditions, malformed UTF-8
+sequences, as well as correctly encoded UTF-8 sequences of Unicode code
+points that should never occur in a correct UTF-8 file.
+
+According to ISO 10646-1:2000, sections D.7 and 2.3c, a device
+receiving UTF-8 shall interpret a "malformed sequence in the same way
+that it interprets a character that is outside the adopted subset" and
+"characters that are not within the adopted subset shall be indicated
+to the user" by a receiving device. One commonly used approach in
+UTF-8 decoders is to replace any malformed UTF-8 sequence by a
+replacement character (U+FFFD), which looks a bit like an inverted
+question mark, or a similar symbol. It might be a good idea to
+visually distinguish a malformed UTF-8 sequence from a correctly
+encoded Unicode character that is just not available in the current
+font but otherwise fully legal, even though ISO 10646-1 doesn't
+mandate this. In any case, just ignoring malformed sequences or
+unavailable characters does not conform to ISO 10646, will make
+debugging more difficult, and can lead to user confusion.
+
+Please check, whether a malformed UTF-8 sequence is (1) represented at
+all, (2) represented by exactly one single replacement character (or
+equivalent signal), and (3) the following quotation mark after an
+illegal UTF-8 sequence is correctly displayed, i.e. proper
+resynchronization takes place immediately after any malformed
+sequence. This file says "THE END" in the last line, so if you don't
+see that, your decoder crashed somehow before, which should always be
+cause for concern.
+
+All lines in this file are exactly 79 characters long (plus the line
+feed). In addition, all lines end with "|", except for the two test
+lines 2.1.1 and 2.2.1, which contain non-printable ASCII controls
+U+0000 and U+007F. If you display this file with a fixed-width font,
+these "|" characters should all line up in column 79 (right margin).
+This allows you to test quickly, whether your UTF-8 decoder finds the
+correct number of characters in every line, that is whether each
+malformed sequences is replaced by a single replacement character.
+
+Note that, as an alternative to the notion of malformed sequence used
+here, it is also a perfectly acceptable (and in some situations even
+preferable) solution to represent each individual byte of a malformed
+sequence with a replacement character. If you follow this strategy in
+your decoder, then please ignore the "|" column.
+
+
+Here come the tests: |
+ |
+1 Some correct UTF-8 text |
+ |
+You should see the Greek word 'kosme': "κόσμε" |
+ |
+2 Boundary condition test cases |
+ |
+2.1 First possible sequence of a certain length |
+ |
+2.1.1 1 byte (U-00000000): "

+
+LNAV – The Logfile Navigator
+
+The Log File Navigator, lnav for short, is an advanced log file viewer
+for the small-scale. It is a terminal application that can understand
+your log files and make it easy for you to find problems with little
+to no setup.
+
+Screenshot
+
+The following screenshot shows a syslog file. Log lines are displayed
+with highlights. Errors are red and warnings are yellow.

+
+Features
+
+ • Log messages from different files are collated together
+ into a single view
+ • Automatic detection of log format
+ • Automatic decompression of GZip and BZip2 files
+ • Filter log messages based on regular expressions
+ • Use SQL to analyze your logs
+ • And more...
+
+Installation
+
+Download a statically-linked binary for Linux/MacOS from the release
+page[1]
+
+ ▌[1] - https://github.com/tstack/lnav/releases/latest#release-artifacts
+
+Usage
+
+The only file installed is the executable,  lnav . You can execute it
+with no arguments to view the default set of files:
+
+ ▌$ lnav 
+
+You can view all the syslog messages by running:
+
+ ▌$ lnav /var/log/messages* 
+
+Usage with  systemd-journald 
+
+On systems running  systemd-journald , you can use  lnav  as the
+pager:
+
+ ▌$ journalctl | lnav 
+
+or in follow mode:
+
+ ▌$ journalctl -f | lnav 
+
+Since  journalctl 's default output format omits the year, if you are
+viewing logs which span multiple years you will need to change the
+output format to include the year, otherwise  lnav  gets confused:
+
+ ▌$ journalctl -o short-iso | lnav 
+
+It is also possible to use  journalctl 's json output format and  lnav
+will make use of additional fields such as PRIORITY and _SYSTEMD_UNIT:
+
+ ▌$ journalctl -o json | lnav 
+
+In case some MESSAGE fields contain special characters such as ANSI
+color codes which are considered as unprintable by journalctl,
+specifying  journalctl 's  -a  option might be preferable in order to
+output those messages still in a non binary representation:
+
+ ▌$ journalctl -a -o json | lnav 
+
+If using systemd v236 or newer, the output fields can be limited to
+the ones actually recognized by  lnav  for increased efficiency:
+
+ ▌$ journalctl -o json --output-fields=MESSAGE,PRIORITY,_PID,SYSLOG_IDENTIFIER,_SYSTEMD_UNIT | lnav 
+
+If your system has been running for a long time, for increased
+efficiency you may want to limit the number of log lines fed into  lnav
+, e.g. via  journalctl 's  -n  or  --since=...  options.
+
+In case of a persistent journal, you may want to limit the number of
+log lines fed into  lnav  via  journalctl 's  -b  option.

+Building From Source
+
+Prerequisites
+
+The following software packages are required to build lnav:
+
+ • gcc/clang - A C++14-compatible compiler.
+ • libpcre - The Perl Compatible Regular Expression
+ (PCRE) library.
+ • sqlite - The SQLite database engine. Version 3.9.0
+ or higher is required.
+ • ncurses - The ncurses text UI library.
+ • readline - The readline line editing library.
+ • zlib - The zlib compression library.
+ • bz2 - The bzip2 compression library.
+ • libcurl - The cURL library for downloading files
+ from URLs. Version 7.23.0 or higher is required.
+ • libarchive - The libarchive library for opening archive
+ files, like zip/tgz.
+ • wireshark - The 'tshark' program is used to interpret
+ pcap files.
+
+Build
+
+Lnav follows the usual GNU style for configuring and installing
+software:
+
+Run  ./autogen.sh  if compiling from a cloned repository.
+
+ ▌$ ./configure 
+ ▌$ make 
+ ▌$ sudo make install 
+
+See Also
+
+Angle-grinder[1] is a tool to slice and dice log files on the
+command-line. If you're familiar with the SumoLogic query language,
+you might find this tool more comfortable to work with.

+with no arguments to view the default set of files:
+
+ ▌$ lnav 
+
+You can view all the syslog messages by running:
+
+ ▌$ lnav /var/log/messages* 
+
+Usage with  systemd-journald 
+
+On systems running  systemd-journald , you can use  lnav  as the
+pager:
+
+ ▌$ journalctl | lnav 
+
+or in follow mode:
+
+ ▌$ journalctl -f | lnav 
+
+Since  journalctl 's default output format omits the year, if you are
+viewing logs which span multiple years you will need to change the
+output format to include the year, otherwise  lnav  gets confused:
+
+ ▌$ journalctl -o short-iso | lnav 
+
+It is also possible to use  journalctl 's json output format and  lnav
+will make use of additional fields such as PRIORITY and _SYSTEMD_UNIT:
+
+ ▌$ journalctl -o json | lnav 
+
+In case some MESSAGE fields contain special characters such as ANSI
+color codes which are considered as unprintable by journalctl,
+specifying  journalctl 's  -a  option might be preferable in order to
+output those messages still in a non-binary representation:
+
+ ▌$ journalctl -a -o json | lnav 
+
+If using systemd v236 or newer, the output fields can be limited to
+the ones actually recognized by  lnav  for increased efficiency:
+
+ ▌$ journalctl -o json --output-fields=MESSAGE,PRIORITY,_PID,SYSLOG_IDENTIFIER,_SYSTEMD_UNIT | lnav 
+
+If your system has been running for a long time, for increased
+efficiency you may want to limit the number of log lines fed into  lnav
+, e.g. via  journalctl 's  -n  or  --since=...  options.
+
+In case of a persistent journal, you may want to limit the number of
+log lines fed into  lnav  via  journalctl 's  -b  option.

+
+lnav
+
+A fancy log file viewer for the terminal.
+
+Overview
+
+The Logfile Navigator, lnav, is an enhanced log file viewer that takes
+advantage of any semantic information that can be gleaned from the
+files being viewed, such as timestamps and log levels. Using this
+extra semantic information, lnav can do things like interleaving
+messages from different files, generate histograms of messages over
+time, and providing hotkeys for navigating through the file. It is
+hoped that these features will allow the user to quickly and
+efficiently zero in on problems.
+
+Opening Paths/URLs
+
+The main arguments to lnav are the files, directories, glob patterns,
+or URLs to be viewed. If no arguments are given, the default syslog
+file for your system will be opened. These arguments will be polled
+periodically so that any new data or files will be automatically
+loaded. If a previously loaded file is removed or replaced, it will be
+closed and the replacement opened.
+
+Note: When opening SFTP URLs, if the password is not provided for the
+host, the SSH agent can be used to do authentication.
+
+Options
+
+Lnav takes a list of files to view and/or you can use the flag
+arguments to load well-known log files, such as the syslog log files.
+The flag arguments are:
+
+ • -a Load all of the most recent log file types.
+ • -r Recursively load files from the given directory
+ hierarchies.
+ • -R Load older rotated log files as well.
+
+When using the flag arguments, lnav will look for the files relative
+to the current directory and its parent directories. In other words,
+if you are working within a directory that has the well-known log
+files, those will be preferred over any others.
+
+If you do not want the default syslog file to be loaded when no files
+are specified, you can pass the -N flag.
+
+Any files given on the command-line are scanned to determine their log
+file format and to create an index for each line in the file. You do
+not have to manually specify the log file format. The currently
+supported formats are: syslog, apache, strace, tcsh history, and
+generic log files with timestamps.
+
+Lnav will also display data piped in on the standard input. The
+following options are available when doing so:
+
+ • -t Prepend timestamps to the lines of data being read
+ in on the standard input.
+ • -w file Write the contents of the standard input to
+ this file.
+
+To automatically execute queries or lnav commands after the files have
+been loaded, you can use the following options:
+
+ • -c cmd A command, query, or file to execute. The
+ first character determines the type of operation: a colon
+ ( : ) is used for the built-in commands; a semi-colon ( ;
+ ) for SQL queries; and a pipe symbol ( | ) for executing
+ a file containing other commands. For example, to open
+ the file "foo.log" and go to the tenth line in the file,
+ you can do:
+
+ ┃lnav -c ':goto 10' foo.log
+
+ This option can be given multiple times to execute
+ multiple operations in sequence.
+ • -f file A file that contains commands, queries, or
+ files to execute. This option is a shortcut for -c '|file'
+ . You can use a dash ( - ) to execute commands from the
+ standard input.
+
+To execute commands/queries without the opening the interactive text
+UI, you can pass the -n option. This combination of options allows
+you to write scripts for processing logs with lnav. For example, to
+get a list of IP addresses that dhclient has bound to in CSV format:
+
+ ┃#! /usr/bin/lnav -nf
+ ┃
+ ┃# Usage: dhcp_ip.lnav /var/log/messages
+ ┃# Only include lines that look like:
+ ┃# Apr 29 00:31:56 example-centos5 dhclient: bound to 10.1.10.103 -- renewal in 9938 seconds.
+ ┃
+ ┃:filter-in dhclient: bound to
+ ┃
+ ┃# The log message parser will extract the IP address
+ ┃# as col_0, so we select that and alias it to "dhcp_ip".
+ ┃;select distinct col_0 as dhcp_ip from logline;
+ ┃
+ ┃# Finally, write the results of the query to stdout.
+ ┃:write-csv-to -
+
+Display
+
+The main part of the display shows the log lines from the files
+interleaved based on time-of-day. New lines are automatically loaded
+as they are appended to the files and, if you are viewing the bottom
+of the files, lnav will scroll down to display the new lines, much
+like tail -f .
+
+On color displays, the lines will be highlighted as follows:
+
+ • Errors will be colored in red;
+ • warnings will be yellow;
+ • boundaries between days will be underlined; and
+ • various color highlights will be applied to: IP
+ addresses, SQL keywords, XML tags, file and line numbers
+ in Java backtraces, and quoted strings.
+
+To give you an idea of where you are spatially, the right side of the
+display has a proportionally sized 'scroll bar' that indicates your
+current position in the files. The scroll bar will also show areas of
+the file where warnings or errors are detected by coloring the bar
+yellow or red, respectively. Tick marks will also be added to the left
+and right hand side of the bar, for search hits and bookmarks.
+
+A bar on the left side is color coded and broken up to indicate which
+messages are from the same file. Pressing the left-arrow or h will
+reveal the source file names for each message and pressing again will
+show the full paths.
+
+Above and below the main body are status lines that display:
+
+ • the current time;
+ • the name of the file the top line was pulled from;
+ • the log format for the top line;
+ • the current view;
+ • the line number for the top line in the display;
+ • the current search hit, the total number of hits, and
+ the search term;
+
+If the view supports filtering, there will be a status line showing
+the following:
+
+ • the number of enabled filters and the total number of
+ filters;
+ • the number of lines not displayed because of filtering.
+
+To edit the filters, you can press TAB to change the focus from the
+main view to the filter editor. The editor allows you to create,
+enable/disable, and delete filters easily.
+
+Finally, the last line on the display is where you can enter search
+patterns and execute internal commands, such as converting a unix-
+timestamp into a human-readable date. The command-line is implemented
+using the readline library, so the usual set of keyboard shortcuts are
+available. Most commands and searches also support tab-completion.
+
+The body of the display is also used to display other content, such
+as: the help file, histograms of the log messages over time, and SQL
+results. The views are organized into a stack so that any time you
+activate a new view with a key press or command, the new view is
+pushed onto the stack. Pressing the same key again will pop the view
+off of the stack and return you to the previous view. Note that you
+can always use q to pop the top view off of the stack.
+
+Default Key Bindings
+
+Views
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ ? View/leave this help message.
+ q Leave the current view or quit the program when in
+ the log file view.
+ Q Similar to q , except it will try to sync the top
+ time between the current and former views. For
+ example, when leaving the spectrogram view with Q
+ , the top time in that view will be matched to the
+ top time in the log view.
+ TAB Toggle focusing on the filter editor or the main
+ view.
+ a/A Restore the view that was previously popped with q
+ / Q . The A hotkey will try to match the top
+ times between the two views.
+ X Close the current text file or log file.
+
+Spatial Navigation
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════════
+ g/Home Move to the top of the file.
+ G/End Move to the end of the file. If the view is
+ already at the end, it will move to the last line.
+ SPACE/PgDn Move down a page.
+ b/PgUp Move up a page.
+ j/↓ Move down a line.
+ k/↑ Move up a line.
+ h/← Move to the left. In the log view, moving left
+ will reveal the source log file names for each
+ line. Pressing again will reveal the full path.
+ l/→ Move to the right.
+ H/Shift ← Move to the left by a smaller increment.
+ L/Shift → Move to the right by a smaller increment.
+ e/E Move to the next/previous error.
+ w/W Move to the next/previous warning.
+ n/N Move to the next/previous search hit. When pressed
+ repeatedly within a short time, the view will move
+ at least a full page at a time instead of moving
+ to the next hit.
+ f/F Move to the next/previous file. In the log view,
+ this moves to the next line from a different file.
+ In the text view, this rotates the view to the
+ next file.
+ >/< Move horizontally to the next/previous search hit.
+ o/O Move forward/backward to the log message with a
+ matching 'operation ID' (opid) field.
+ u/U Move forward/backward through any user bookmarks
+ you have added using the 'm' key. This hotkey will
+ also jump to the start of any log partitions that
+ have been created with the 'partition-name'
+ command.
+ s/S Move to the next/previous "slow down" in the log
+ message rate. A slow down is detected by measuring
+ how quickly the message rate has changed over the
+ previous several messages. For example, if one
+ message is logged every second for five seconds
+ and then the last message arrives five seconds
+ later, the last message will be highlighted as a
+ slow down.
+ {/} Move to the previous/next location in history.
+ Whenever you jump to a new location in the view,
+ the location will be added to the history. The
+ history is not updated when using only the arrow
+ keys.
+
+Chronological Navigation
+
+ Key(s) Action
+══════════════════════════════════════════════════════════════════
+ d/D Move forward/backward 24 hours from the current
+ position in the log file.
+ 1-6/Shift 1-6 Move to the next/previous n'th ten minute of the
+ hour. For example, '4' would move to the first log
+ line in the fortieth minute of the current hour in
+ the log. And, '6' would move to the next hour
+ boundary.
+ 7/8 Move to the previous/next minute.
+ 0/Shift 0 Move to the next/previous day boundary.
+ r/R Move forward/backward based on the relative time
+ that was last used with the 'goto' command. For
+ example, executing ':goto a minute later' will
+ move the log view forward a minute and then
+ pressing 'r' will move it forward a minute again.
+ Pressing 'R' will then move the view in the
+ opposite direction, so backwards a minute.
+
+Bookmarks
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ m Mark/unmark the line at the top of the display.
+ The line will be highlighted with reverse video to
+ indicate that it is a user bookmark. You can use
+ the u hotkey to iterate through marks you have
+ added.
+ M Mark/unmark all the lines between the top of the
+ display and the last line marked/unmarked.
+ J Mark/unmark the next line after the previously
+ marked line.
+ K Like J except it toggles the mark on the
+ previous line.
+ c Copy the marked text to the X11 selection buffer
+ or OS X clipboard.
+ C Clear all marked lines.
+
+Display options
+
+ Key(s) Action
+══════════════════════════════════════════════════════════════════
+ P Switch to/from the pretty-printed view of the log
+ or text files currently displayed. In this view,
+ structured data, such as XML, will be reformatted
+ to make it easier to read.
+ t Switch to/from the text file view. The text file
+ view is for any files that are not recognized as
+ log files.
+ = Pause/unpause loading of new file data.
+ Ctrl-L (Lo-fi mode) Exit screen-mode and write the
+ displayed log lines in plain text to the terminal
+ until a key is pressed. Useful for copying long
+ lines from the terminal without picking up any of
+ the extra decorations.
+ T Toggle the display of the "elapsed time" column
+ that shows the time elapsed since the beginning of
+ the logs or the offset from the previous bookmark.
+ Sharp changes in the message rate are highlighted
+ by coloring the separator between the time column
+ and the log message. A red highlight means the
+ message rate has slowed down and green means it
+ has sped up. You can use the "s/S" hotkeys to scan
+ through the slow downs.
+ i View/leave a histogram of the log messages over
+ time. The histogram counts the number of displayed
+ log lines for each bucket of time. The bars are
+ layed out horizontally with colored segments
+ representing the different log levels. You can use
+ the z hotkey to change the size of the time
+ buckets (e.g. ten minutes, one hour, one day).
+ I Switch between the log and histogram views while
+ keeping the time displayed at the top of each view
+ in sync. For example, if the top line in the log
+ view is "11:40", hitting I will switch to the
+ histogram view and scrolled to display "11:00" at
+ the top (if the zoom level is hours).
+ z/Shift Z Zoom in or out one step in the histogram view.
+ v Switch to/from the SQL result view.
+ V Switch between the log and SQL result views while
+ keeping the top line number in the log view in
+ sync with the log_line column in the SQL view. For
+ example, doing a query that selects for "
+ log_idle_msecs" and "log_line", you can move the
+ top of the SQL view to a line and hit 'V' to
+ switch to the log view and move to the line number
+ that was selected in the "log_line" column. If
+ there is no "log_line" column, lnav will find the
+ first column with a timestamp and move to
+ corresponding time in the log view.
+ TAB/Shift TAB In the SQL result view, cycle through the columns
+ that are graphed. Initially, all number values are
+ displayed in a stacked graph. Pressing TAB will
+ change the display to only graph the first column.
+ Repeatedly pressing TAB will cycle through the
+ columns until they are all graphed again.
+ p In the log view: enable or disable the display of
+ the fields that the log message parser knows about
+ or has discovered. This overlay is temporarily
+ enabled when the semicolon key (;) is pressed so
+ that it is easier to write queries.
+ In the DB view: enable or disable the display of
+ values in columns containing JSON-encoded values
+ in the top row. The overlay will display the JSON-
+ Pointer reference and value for all fields in the
+ JSON data.
+ CTRL-W Toggle word-wrapping.
+ CTRL-P Show/hide the data preview panel that may be
+ opened when entering commands or SQL queries.
+ CTRL-F Toggle the enabled/disabled state of all filters
+ in the current view.
+ x Toggle the hiding of log message fields. The
+ hidden fields will be replaced with three bullets
+ and highlighted in yellow.
+ F2 Toggle mouse support.
+
+Query
+
+ Key(s) Action
+═════════════════════════════════════════════════════════════════════════════
+ /regexp Start a search for the given regular expression.
+ The search is live, so when there is a pause in
+ typing, the currently running search will be
+ canceled and a new one started. The first ten
+ lines that match the search will be displayed in
+ the preview window at the bottom of the view.
+ History is maintained for your searches so you can
+ rerun them easily. Words that are currently
+ displayed are also available for tab-completion,
+ so you can easily search for values without
+ needing to copy-and-paste the string. If there is
+ an error encountered while trying to interpret the
+ expression, the error will be displayed in red on
+ the status line. While the search is active, the '
+ hits' field in the status line will be green, when
+ finished it will turn back to black.
+ :<command> Execute an internal command. The commands are
+ listed below. History is also supported in this
+ context as well as tab-completion for commands and
+ some arguments. The result of the command replaces
+ the command you typed.
+ ;<sql> Execute an SQL query. Most supported log file
+ formats provide a sqlite virtual table backend
+ that can be used in queries. See the SQL section
+ below for more information.
+ |<script> [arg1 .. argN] Execute an lnav script contained in a format
+ directory (e.g. ~/.lnav/formats/default). The
+ script can contain lines starting with : , ; ,
+ or | to execute commands, SQL queries or execute
+ other files in lnav. Any values after the script
+ name are treated as arguments can be referenced in
+ the script using $1 , $2 , and so on, like in a
+ shell script.
+ CTRL+], ESCAPE Abort command-line entry started with / , :
+, ;
+ , or | .
+
+ ┃ Note: The regular expression format used by is PCRE
+ ┃ (Perl-Compatible Regular Expressions). For example,
+ ┃ if you wanted to search for ethernet device names,
+ ┃ regardless of their ID number, you can type:
+ ┃
+ ┃ eth\d+
+ ┃
+ ┃ You can find more information about Perl regular
+ ┃ expressions at:
+ ┃
+ ┃ http://perldoc.perl.org/perlre.html
+ ┃
+ ┃ If the search string is not valid PCRE, a search
+ ┃ is done for the exact string instead of doing a
+ ┃ regex search.
+
+Session
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ CTRL-R Reset the session state. This will save the
+ current session state (filters, highlights) and
+ then reset the state to the factory default.
+
+Filter Editor
+
+The following hotkeys are only available when the focus is on the
+filter editor. You can change the focus by pressing TAB.
+
+ Key(s) Action
+═══════════════════════════════════════════════════════════
+ q Switch the focus back to the main view.
+ j/↓ Select the next filter.
+ k/↑ Select the previous filter.
+ o Create a new "out" filter.
+ i Create a new "in" filter .
+ SPACE Toggle the enabled/disabled state of the currently
+ selected filter.
+ t Toggle the type of filter between "in" and "out".
+ ENTER Edit the selected filter.
+ D Delete the selected filter.
+
+Mouse Support (experimental)
+
+If you are using Xterm, or a compatible terminal, you can use the
+mouse to mark lines of text and move the view by grabbing the
+scrollbar.
+
+NOTE: You need to manually enable this feature by setting the LNAV_EXP
+environment variable to "mouse". F2 toggles mouse support.
+
+SQL Queries (experimental)
+
+Lnav has support for performing SQL queries on log files using the
+Sqlite3 "virtual" table feature. For all supported log file types,
+lnav will create tables that can be queried using the subset of SQL
+that is supported by Sqlite3. For example, to get the top ten URLs
+being accessed in any loaded Apache log files, you can execute:
+
+ ┃;select cs_uri_stem, count(*) as total from access_log
+ ┃ group by cs_uri_stem order by total desc limit 10;
+
+The query result view shows the results and graphs any numeric values
+found in the result, much like the histogram view.
+
+The builtin set of log tables are listed below. Note that only the log
+messages that match a particular format can be queried by a particular
+table. You can find the file format and table name for the top log
+message by looking in the upper right hand corner of the log file
+view.
+
+Some commonly used format tables are:
+
+ Name Description
+════════════════════════════════════════════════════════════════
+ access_log Apache common access log format
+ syslog_log Syslog format
+ strace_log Strace log format
+ generic_log 'Generic' log format. This table contains messages
+ from files that have a very simple format with a
+ leading timestamp followed by the message.
+
+NOTE: You can get a dump of the schema for the internal tables, and
+any attached databases, by running the .schema SQL command.
+
+The columns available for the top log line in the view will
+automatically be displayed after pressing the semicolon ( ; ) key. All
+log tables contain at least the following columns:
+
+ Column Description
+═══════════════════════════════════════════════════════════════════
+ log_line The line number in the file, starting at zero.
+ log_part The name of the partition. You can change this
+ column using an UPDATE SQL statement or with the '
+ partition-name' command. After a value is set,
+ the following log messages will have the same
+ partition name up until another name is set.
+ log_time The time of the log entry.
+ log_idle_msecs The amount of time, in milliseconds, between the
+ current log message and the previous one.
+ log_level The log level (e.g. info, error, etc...).
+ log_mark The bookmark status for the line. This column can
+ be written to using an UPDATE query.
+ log_path The full path to the file.
+ log_text The raw line of text. Note that this column is
+ not included in the result of a 'select *', but it
+ does exist.
+
+The following tables include the basic columns as listed above and
+include a few more columns since the log file format is more
+structured.
+
+ • syslog_log
+
+ Column Description
+ ═════════════════════════════════════════════════════════════════
+ log_hostname The hostname the message was received from.
+ log_procname The name of the process that sent the message.
+ log_pid The process ID of the process that sent the
+ message.
+ • access_log (The column names are the same as those in
+ the Microsoft LogParser tool.)
+
+ Column Description
+ ══════════════════════════════════════════════════════════
+ c_ip The client IP address.
+ cs_username The client user name.
+ cs_method The HTTP method.
+ cs_uri_stem The stem portion of the URI.
+ cs_uri_query The query portion of the URI.
+ cs_version The HTTP version string.
+ sc_status The status number returned to the client.
+ sc_bytes The number of bytes sent to the client.
+ cs_referrer The URL of the referring page.
+ cs_user_agent The user agent string.
+ • strace_log (Currently, you need to run strace with
+ the -tt -T options so there are timestamps for each
+ function call.)
+
+ Column Description
+ ═══════════════════════════════════════════════════════
+ funcname The name of the syscall.
+ result The result code.
+ duration The amount of time spent in the syscall.
+ arg0 - arg9 The arguments passed to the syscall.
+
+These tables are created dynamically and not stored in memory or on
+disk. If you would like to persist some information from the tables,
+you can attach another database and create tables in that database.
+For example, if you wanted to save the results from the earlier
+example of a top ten query into the "/tmp/topten.db" file, you can do:
+
+ ┃;attach database "/tmp/topten.db" as topten;
+ ┃;create table topten.foo as select cs_uri_stem, count(*) as total
+ ┃ from access_log group by cs_uri_stem order by total desc
+ ┃ limit 10;
+
+Dynamic logline Table (experimental)
+
+(NOTE: This feature is still very new and not completely reliable yet,
+use with care.)
+
+For log formats that lack message structure, lnav can parse the log
+message and attempt to extract any data fields that it finds. This
+feature is available through the logline log table. This table is
+dynamically created and defined based on the message at the top of the
+log view. For example, given the following log message from "sudo",
+lnav will create the "logline" table with columns for "TTY", "PWD", "
+USER", and "COMMAND":
+
+ ┃May 24 06:48:38 Tim-Stacks-iMac.local sudo[76387]: stack : TTY=ttys003 ; PWD=/Users/stack/github/lbuild ; USER=root ; COMMAND=/bin/echo Hello, World!
+
+Queries executed against this table will then only return results for
+other log messages that have the same format. So, if you were to
+execute the following query while viewing the above line, you might
+get the following results:
+
+ ┃;select USER,COMMAND from logline;
+
+ USER COMMAND
+═════════════════════════════════
+ root /bin/echo Hello, World!
+ mal /bin/echo Goodbye, World!
+
+The log parser works by examining each message for key/value pairs
+separated by an equal sign (=) or a colon (:). For example, in the
+previous example of a "sudo" message, the parser sees the "USER=root"
+string as a pair where the key is "USER" and the value is "root". If
+no pairs can be found, then anything that looks like a value is
+extracted and assigned a numbered column. For example, the following
+line is from "dhcpd":
+
+ ┃Sep 16 22:35:57 drill dhcpd: DHCPDISCOVER from 00:16:ce:54:4e:f3 via hme3
+
+In this case, the lnav parser recognizes that "DHCPDISCOVER", the MAC
+address and the "hme3" device name are values and not normal words.
+So, it builds a table with three columns for each of these values. The
+regular words in the message, like "from" and "via", are then used to
+find other messages with a similar format.
+
+If you would like to execute queries against log messages of different
+formats at the same time, you can use the 'create-logline-table'
+command to permanently create a table using the top line of the log
+view as a template.
+
+Other SQL Features
+
+Environment variables can be used in SQL statements by prefixing the
+variable name with a dollar-sign ($). For example, to read the value
+of the HOME variable, you can do:
+
+ ┃;SELECT $HOME;
+
+To select the syslog messages that have a hostname field that is equal
+to the HOSTNAME variable:
+
+ ┃;SELECT * FROM syslog_log WHERE log_hostname = $HOSTNAME;
+
+NOTE: Variable substitution is done for fields in the query and is not
+a plain text substitution. For example, the following statement WILL
+NOT WORK:
+
+ ┃;SELECT * FROM $TABLE_NAME; -- Syntax error
+
+Access to lnav's environment variables is also available via the "
+environ" table. The table has two columns (name, value) and can be
+read and written to using SQL SELECT, INSERT, UPDATE, and DELETE
+statements. For example, to set the "FOO" variable to the value "BAR":
+
+ ┃;INSERT INTO environ SELECT 'FOO', 'BAR';
+
+As a more complex example, you can set the variable "LAST" to the last
+syslog line number by doing:
+
+ ┃;INSERT INTO environ SELECT 'LAST', (SELECT max(log_line) FROM syslog_log);
+
+A delete will unset the environment variable:
+
+ ┃;DELETE FROM environ WHERE name='LAST';
+
+The table allows you to easily use the results of a SQL query in lnav
+commands, which is especially useful when scripting lnav.
