+# arrayops.bash --- hide some of the nasty syntax for manipulating bash arrays
+# Author: Noah Friedman <friedman@splode.com>
+# Created: 2016-07-08

+
+# Commentary:
+
+# These functions try to tame the syntactic nightmare that is bash array
+# syntax, which makes perl's almost look reasonable.
+#
+# For example the apush function below lets you write:
+#
+# apush arrayvar newval
+#
+# instead of
+#
+# ${arrayvar[${#arrayvar[@]}]}=newval
+#
+# Because seriously, you've got to be kidding me.
+
+# These functions avoid the use of local variables as much as possible
+# (especially wherever modification occurs) because those variable names
+# might shadow the array name passed in. Dynamic scope!
+
+# Code:
+
+#:docstring apush:
+# Usage: apush arrayname val1 {val2 {...}}
+#
+# Appends VAL1 and any remaining arguments to the end of the array
+# ARRAYNAME as new elements.
+#:end docstring:
+apush()
+{
+ eval "$1=(\"\${$1[@]}\" \"\${@:2}\")"
+}
+
+#:docstring apop:
+# Usage: apop arrayname {n}
+#
+# Removes the last element from ARRAYNAME.
+# Optional argument N means remove the last N elements.
+#:end docstring:
+apop()
+{
+ eval "$1=(\"\${$1[@]:0:\${#$1[@]}-${2-1}}\")"
+}
+
+#:docstring aunshift:
+# Usage: aunshift arrayname val1 {val2 {...}}
+#
+# Prepends VAL1 and any remaining arguments to the beginning of the array
+# ARRAYNAME as new elements. The new elements will appear in the same order
+# as given to this function, rather than inserting them one at a time.
+#
+# For example:
+#
+# foo=(a b c)
+# aunshift foo 1 2 3
+# => foo is now (1 2 3 a b c)
+# but
+#
+# foo=(a b c)

+SYNOPSIS
+ autoload [-ps]
+ autoload [-xuremloyv] [function ...]
+ autoload -a directory [-oyv]
+ autoload -f [-oyv]
+ autoload [-h]
+
+ autoreload [function ...]
+
+DESCRIPTION
+
+ An implementation of the 'autoload' functionality built into other
+ shells, of which 'ksh' is the most prominent. It allows for a keeping
+ the process environment small by loading small 'shim' functions into
+ memory that will, on first call, load the full text of the given
+ function and run it. Subsequent calls to the function just run the
+ function.
+
+ 'autoreload' is a synonym for 'autoload -r'. See below.
+
+USAGE
+
+ o Each function to be autoloaded should be defined in a single file,
+ named exactly the same as the function.
+
+ o In order to avoid side effects, do NOT put code other than the
+ function definition in the file. Unless of course you want to do some
+ one-time initialization. But beware that if you reload the function
+ for any reason, you will rerun the initialization code. Make sure
+ your initialization is re-entrant. Or, better yet,
+
+ *** do NOT put code other than the function definition in the file ***
+
+ o These function definition files should be placed in a directory that
+ is in the FPATH environment variable. Subdirectories are NOT scanned.
+
+ o The autoload script should be sourced into the current process as
+ early as possible in process start up. See NOTES below for
+ suggestions.
+
+ o The calls to the autoload function must be made in the current
+ process. If your calls are in their own script, that script must be
+ sourced in. Command line invocations are also sufficient. (But see
+ '-l' below.)
+
+ o The first time the function is called, the shim function that was
+ created by the 'autoload' call is what is executed. This function
+ then goes and finds the appropriate file in FPATH, sources it in and
+ then calls the actual function with any arguments you just passed in
+ to the shim function. Subsequent calls just run the function.
+
+OPTIONS
+
+ -a Autoload (a)ll the functions found in the given directory.
+
+ -f Autoload all the functions found in all the directories on the
+ FPATH.
+
+ -p Print all the autoloaded functions.
+
+ -s Print all the autoloaded functions and add their export status.
+
+ -x Export the specified functions to the environment for use in
+ subshells.
+
+ -u Unset the function, so it can be reloaded.
+
+ -r Reload the shims of the specified functions, even if the functions
+ have been already been executed. This will allow you to modify the
+ functions' source and have the new version executed next time the
+ function is called.
+
+ It would be very easy to modify a function's script, run the
+ function and scratch your head for a long time trying to figure out
+ why your changes are not being executed. That's why we provide the
+ '-e' flag described below for modifications.
+
+ Reloads, of course, only apply in the context of the current session
+ and any future subshell you start from the current session. Existing
+ sessions will need to have the same 'autoload -r' command run in
+ them.
+
+ -e Find the scripts in which the specified functions are defined and
+ start up \$EDITOR on those scripts. Reload the ones that were
+ modified when you exit \$EDITOR. (Note: If you use 'autoload -e foo'
+ to edit function 'foo', and then in your editor you separately load
+ up function 'bar', 'autoload' has no way of knowing that you edited
+ 'bar' and will NOT reload 'bar' for you.)
+
+ Reloads, of course, only apply in the context of the current session
+ and any future subshell you start from the current session. Existing
+ sessions will need to have the same 'autoload -r' command run in
+ them.
+
+ -m Find the scripts in which the specified functions are defined and
+ run \$PAGER on them ('m' is for 'more', because 'p' (page) and 'l'
+ (load) are already used as options in 'autoload').
+
+ -l When autoloading a function, eval the shim immediately in order to
+ load the true function code. See "Using '-l'" in the NOTES below for
+ details.
+
+ -o Optimize. When autoloading, take the time to execute
+
+ 'theCharCount=\$(wc -c \$theFuncFile)'
+
+ for each funcion and
+
+ if \$theCharCount < \$AUTOLOAD_SHIM_OVERHEAD
+
+ don't shim it, just eval directly.
+
+ -y Summar(y). Print the number of loaded, exported and optimized
+ functions.
+
+ -v Turns up the chattiness.
+
+NOTES
+
+ o Calling 'autoload' on a function that already exists (either shimmed
+ or expanded) silently ignores the request to load the shim unless it
+ has been previously removed (-u) or you force the reload (-r).
+
+ o Changing and reloading a function that has been exported does not
+ require it be re-exported; the modifications will appear in
+ subsequent subshells.
+
+ o Using '-1'
+
+ If you are running under set -x and/or set -v, you may see that the
+ shim does not appear to "work"; instead of seeing the shim first and
+ the real code subsequently, you may see the shim evaluated multiple
+ times.
+
+ This may not be an error; review your code. What is most likely
+ happening is that you are calling the function in subshells via
+ backticks or $(), or in a script that is not being sourced into the
+ current environment. If you have not previously called the function
+ in question at your command line or in a script that was sourced into
+ the current envirnoment, then the various subshells are going to
+ encounter the shim and replace with the real code before executing.
+
+ Remember, however, that environment modifications that occur in a
+ subshell are NOT propagated back to the calling shell or over to any
+ sibling shells. So, if you call an autoloaded function in a very
+ tight loop of very many subshells, you may want to make an 'autoload
+ -l' call before you start your loop. '-l' will instruct 'autoload' to
+ bypass the shim creation and just source in the function's file
+ directly. For a few calls, the overhead of repeatedly running the
+ shim is not expensive, but in a tight loop, it might be. Caveat
+ Programer.
+
+ o Although the number of functions in the environment does not change
+ by using 'autoload', the amount of memory they take up can be greatly
+ reduced, depending on the size of your functions. If you have a lot
+ of small functions, then it is possible that the shim text will be
+ larger than your actual functions, rendering the memory savings moot.
+
+ 'small' in this case can be determined by calling the function
+ 'autoload_calc_shimsize' with the name of the function to determine
+ its shim size.
+
+ o In order to support the -p and -s options, we need a way to determine
+ if a function 'func' has been autoloaded or if it was loaded
+ diredctly. In order to do that, we modify the function's code by
+ adding the text
+
+ local AUTOLOADED='func';
+
+ to the shim and to the actual function text, just after the opening
+ brace. Then supporting -p and -s is just a matter of grepping through
+ all the function text in memory. Even though grepping through the
+ environment may not be the most efficient way to support this, it is
+ the simplest to implement for -p and -s operations that are not
+ heavily used.
+
+ As a consquence of this (and other reasons), the AUTOLOAD* namespace
+ is reserved for autoloading. Make sure you check any functions that
+ you bring under autoload for use of variables or functions that start
+ with AUTOLOAD and change them.
+
+ o The easiest way to load shims for all functions on the FPATH is to run
+
+ autoload -f -x
+
+ in the profile that gets run for login shells.
+
+ When called in the profile of a login shell where no definitions
+ exist, -f will load all functions it can find on FPATH and -x will
+ export all of those functions to be available in subshells when this
+ is called in a login shell. Using this option will relieve you of the
+ need to call 'autoload' after Every Single Function Definition, nor
+ will you need to call it in subshells.
+
+ The only thing left to do is to load up the autoload function itself
+ and its helper functions. That needs to happen in your profile:
+
+ export FPATH=~/functions # or wherever you stash them
+ if [ -z $(declare -F autoload) ]
+ then
+ . ~/bin/autoload # or wherever you've put it
+ fi
+
+ The 'if' statement is used to make sure we don't reload autoload
+ needlessly. Sourcing in the autoload script loads the 'autoload'
+ function and all of its support functions. Additionally, we export
+ all of these functions so that they are available in subshells; you
+ do not have to re-source the autoload file in '.bashrc'.
+
+ o Even with all of these shenanigans, you will find cases where no
+ matter how hard you try, your autoloaded functions will be
+ unavailable to you, even if you run 'autoload -x -f'. The typical
+ condition for this is starting up not a subshell, but a brand new
+ DIFFERENT shell. And the typical example of this is git extentions.
+
+ At the time of this writing, git extentions work by taking a command
+ 'git foo' and looking for a file 'git-foo' on the path. 'git' then
+ executes 'git-foo' in a new shell - it executes your command in
+ /bin/sh. That's not a subshell of your process. It will not get your
+ exported shell functions. Ballgame over.
+
+ If you find that you want your functions to be available in such
+ circumstances, convert them back to plain old scripts, make sure they
+ are 'sh' compliant and take the read/parse hit every time they are
+ run.

+Some examples of ready-to-dynamic-load builtins. Most of the
+examples given are reimplementations of standard commands whose
+execution time is dominated by process startup time. The
+exceptions are sleep, which allows you to sleep for fractions
+of a second, finfo, which provides access to the rest of the
+elements of the `stat' structure that `test' doesn't let you
+see, and pushd/popd/dirs, which allows you to compile them out
+of the shell.
+
+All of the new builtins in ksh93 that bash didn't already have
+are included here, as is the ksh `print' builtin.
+
+The configure script in the top-level source directory uses the
+support/shobj-conf script to set the right values in the Makefile,
+so you should not need to change the Makefile. If your system
+is not supported by support/shobj-conf, and it has the necessary
+facilities for building shared objects and support for the
+dlopen/dlsyn/dlclose/dlerror family of functions, please make
+the necessary changes to support/shobj-conf and send the changes
+to bash-maintainers@gnu.org.
+
+Loadable builtins are loaded into a running shell with
+
+ enable -f filename builtin-name
+
+enable uses a simple reference-counting scheme to avoid unloading a
+shared object that implements more than one loadable builtin before
+all loadable builtins implemented in the object are removed.
+
+Many of the details needed by builtin writers are found in hello.c,
+the canonical example. There is no real `builtin writers' programming
+guide'. The file template.c provides a template to use for creating
+new loadable builtins.
+
+The file "Makefile.inc" is created using the same values that configure
+writes into Makefile.in, and is installed in the same directory as the
+rest of the example builtins. It's intended to be a start at something
+that can be modified or included to help you build your own loadables
+without having to search for the right CFLAGS and LDFLAGS.
+
+basename.c Return non-directory portion of pathname.
+cat.c cat(1) replacement with no options - the way cat was intended.
+dirname.c Return directory portion of pathname.
+fdflags.c Change the flag associated with one of bash's open file desriptors.
+finfo.c Print file info.
+head.c Copy first part of files.
+hello.c Obligatory "Hello World" / sample loadable.
+id.c POSIX.2 user identity.
+ln.c Make links.
+loadables.h File loadable builtins can include for shell definitions.
+logname.c Print login name of current user.
+Makefile.in Simple makefile for the sample loadable builtins.
+Makefile.inc.in Sample makefile to use for loadable builtin development.
+mkdir.c Make directories.
+mypid.c Add $MYPID variable, demonstrate use of unload hook functio.n
+necho.c echo without options or argument interpretation.
+pathchk.c Check pathnames for validity and portability.
+print.c Loadable ksh-93 style print builtin.
+printenv.c Minimal builtin clone of BSD printenv(1).
+push.c Anyone remember TOPS-20?
+realpath.c Canonicalize pathnames, resolving symlinks.
+rm.c Remove files and directories.
+rmdir.c Remove directory.
+seq.c Print a sequence of decimal or floating point numbers.
+setpgid.c Set a process's pgrp; example of how to wrap a system call.
+sleep.c sleep for fractions of a second.
+stat.c populate an associative array with information about a file
+strftime.c Loadable builtin interface to strftime(3).
+sync.c Sync the disks by forcing pending filesystem writes to complete.
+tee.c Duplicate standard input.
+template.c Example template for loadable builtin.
+truefalse.c True and false builtins.
+tty.c Return terminal name.
+uname.c Print system information.
+unlink.c Remove a directory entry.
+whoami.c Print out username of current user.

+This illustrates how to build a perl interpreter into bash. It's not
+especially useful; more a proof of concept (it provides none of the

+
+This *may* require adding "-rpath /path/to/perl/CORE" and -lperl options
+when compiling bash itself.
