Last change: 2019 Jan 17 + + + VIM REFERENCE MANUAL by Bram Moolenaar + + +Various commands *various* + +1. Various commands |various-cmds| +2. Using Vim like less or more |less| + +============================================================================== +1. Various commands *various-cmds* + + *CTRL-L* +CTRL-L Clear and redraw the screen. The redraw may happen + later, after processing typeahead. + + *:redr* *:redraw* +:redr[aw][!] Redraw the screen right now. When ! is included it is + cleared first. + Useful to update the screen halfway executing a script + or function. Also when halfway a mapping and + 'lazyredraw' is set. + + *:redraws* *:redrawstatus* +:redraws[tatus][!] Redraw the status line of the current window. When ! + is included all status lines are redrawn. + Useful to update the status line(s) when 'statusline' + includes an item that doesn't cause automatic + updating. + + *:redrawt* *:redrawtabline* +:redrawt[abline] Redraw the tabline. Useful to update the tabline when + 'tabline' includes an item that doesn't trigger + automatic updating. + + *N<Del>* +<Del> When entering a number: Remove the last digit. + Note: if you like to use <BS> for this, add this + mapping to your .vimrc: > + :map CTRL-V <BS> CTRL-V <Del> +< See |:fixdel| if your <Del> key does not do what you + want. + +:as[cii] or *ga* *:as* *:ascii* +ga Print the ascii value of the character under the + cursor in decimal, hexadecimal and octal. + Mnemonic: Get Ascii value. + + For example, when the cursor is on a 'R': + <R> 82, Hex 52, Octal 122 ~ + When the character is a non-standard ASCII character, + but printable according to the 'isprint' option, the + non-printable version is also given. + + When the character is larger than 127, the <M-x> form + is also printed. For example: + <~A> <M-^A> 129, Hex 81, Octal 201 ~ + <p> <|~> <M-~> 254, Hex fe, Octal 376 ~ + (where <p> is a special character) + + The <Nul> character in a file is stored internally as + <NL>, but it will be shown as: + <^@> 0, Hex 00, Octal 000 ~ + + If the character has composing characters these are + also shown. The value of 'maxcombine' doesn't matter. + + If the character can be inserted as a digraph, also + output the two characters that can be used to create + the character: + <ö> 246, Hex 00f6, Oct 366, Digr o: ~ + This shows you can type CTRL-K o : to insert ö. + + {not in Vi} + + *g8* +g8 Print the hex values of the bytes used in the + character under the cursor, assuming it is in |UTF-8| + encoding. This also shows composing characters. The + value of 'maxcombine' doesn't matter. + Example of a character with two composing characters: + e0 b8 81 + e0 b8 b9 + e0 b9 89 ~ + {not in Vi} {only when compiled with the |+multi_byte| + feature} + + *8g8* +8g8 Find an illegal UTF-8 byte sequence at or after the + cursor. This works in two situations: + 1. when 'encoding' is any 8-bit encoding + 2. when 'encoding' is "utf-8" and 'fileencoding' is + any 8-bit encoding + Thus it can be used when editing a file that was + supposed to be UTF-8 but was read as if it is an 8-bit + encoding because it contains illegal bytes. + Does not wrap around the end of the file. + Note that when the cursor is on an illegal byte or the + cursor is halfway a multi-byte character the command + won't move the cursor. + {not in Vi} {only when compiled with the |+multi_byte| + feature} + + *:p* *:pr* *:print* *E749* +:[range]p[rint] [flags] + Print [range] lines (default current line). + Note: If you are looking for a way to print your text + on paper see |:hardcopy|. In the GUI you can use the + File.Print menu entry. + See |ex-flags| for [flags]. + The |:filter| command can be used to only show lines + matching a pattern. + +:[range]p[rint] {count} [flags] + Print {count} lines, starting with [range] (default + current line |cmdline-ranges|). + See |ex-flags| for [flags]. + + *:P* *:Print* +:[range]P[rint] [count] [flags] + Just as ":print". Was apparently added to Vi for + people that keep the shift key pressed too long... + Note: A user command can overrule this command. + See |ex-flags| for [flags]. + + *:l* *:list* +:[range]l[ist] [count] [flags] + Same as :print, but display unprintable characters + with '^' and put $ after the line. This can be + further changed with the 'listchars' option. + See |ex-flags| for [flags]. + + *:nu* *:number* +:[range]nu[mber] [count] [flags] + Same as :print, but precede each line with its line + number. (See also 'highlight' and 'numberwidth' + option). + See |ex-flags| for [flags]. + + *:#* +:[range]# [count] [flags] + synonym for :number. + + *:#!* +:#!{anything} Ignored, so that you can start a Vim script with: > + #!vim -S + echo "this is a Vim script" + quit +< + *:z* *E144* +:{range}z[+-^.=]{count} Display several lines of text surrounding the line + specified with {range}, or around the current line + if there is no {range}. If there is a {count}, that's + how many lines you'll see; if there is only one window + then twice the value of the 'scroll' option is used, + otherwise the current window height minus 3 is used. + + If there is a {count} the 'window' option is set to + its value. + + :z can be used either alone or followed by any of + several punctuation marks. These have the following + effect: + + mark first line last line new cursor line ~ + ---- ---------- --------- ------------ + + current line 1 scr forward 1 scr forward + - 1 scr back current line current line + ^ 2 scr back 1 scr back 1 scr back + . 1/2 scr back 1/2 scr fwd 1/2 scr fwd + = 1/2 scr back 1/2 scr fwd current line + + Specifying no mark at all is the same as "+". + If the mark is "=", a line of dashes is printed + around the current line. + +:{range}z#[+-^.=]{count} *:z#* + Like ":z", but number the lines. + {not in all versions of Vi, not with these arguments} + + *:=* +:= [flags] Print the last line number. + See |ex-flags| for [flags]. + +:{range}= [flags] Prints the last line number in {range}. For example, + this prints the current line number: > + :.= +< See |ex-flags| for [flags]. + +:norm[al][!] {commands} *:norm* *:normal* + Execute Normal mode commands {commands}. This makes + it possible to execute Normal mode commands typed on + the command-line. {commands} are executed like they + are typed. For undo all commands are undone together. + Execution stops when an error is encountered. + + If the [!] is given, mappings will not be used. + Without it, when this command is called from a + non-remappable mapping (|:noremap|), the argument can + be mapped anyway. + + {commands} should be a complete command. If + {commands} does not finish a command, the last one + will be aborted as if <Esc> or <C-C> was typed. + This implies that an insert command must be completed + (to start Insert mode, see |:startinsert|). A ":" + command must be completed as well. And you can't use + "Q" or "gQ" to start Ex mode. + + The display is not updated while ":normal" is busy. + + {commands} cannot start with a space. Put a count of + 1 (one) before it, "1 " is one space. + + The 'insertmode' option is ignored for {commands}. + + This command cannot be followed by another command, + since any '|' is considered part of the command. + + This command can be used recursively, but the depth is + limited by 'maxmapdepth'. + + An alternative is to use |:execute|, which uses an + expression as argument. This allows the use of + printable characters to represent special characters. + + Example: > + :exe "normal \<c-w>\<c-w>" +< {not in Vi, of course} + +:{range}norm[al][!] {commands} *:normal-range* + Execute Normal mode commands {commands} for each line + in the {range}. Before executing the {commands}, the + cursor is positioned in the first column of the range, + for each line. Otherwise it's the same as the + ":normal" command without a range. + {not in Vi} + + *:sh* *:shell* *E371* +:sh[ell] This command starts a shell. When the shell exits + (after the "exit" command) you return to Vim. The + name for the shell command comes from 'shell' option. + *E360* + Note: This doesn't work when Vim on the Amiga was + started in QuickFix mode from a compiler, because the + compiler will have set stdin to a non-interactive + mode. + + *:!cmd* *:!* *E34* +:!{cmd} Execute {cmd} with the shell. See also the 'shell' + and 'shelltype' option. + + Any '!' in {cmd} is replaced with the previous + external command (see also 'cpoptions'). But not when + there is a backslash before the '!', then that + backslash is removed. Example: ":!ls" followed by + ":!echo ! \! \\!" executes "echo ls ! \!". + + A '|' in {cmd} is passed to the shell, you cannot use + it to append a Vim command. See |:bar|. + + If {cmd} contains "%" it is expanded to the current + file name. Special characters are not escaped, use + quotes to avoid their special meaning: > + :!ls "%" +< If the file name contains a "$" single quotes might + work better (but a single quote causes trouble): > + :!ls '%' +< This should always work, but it's more typing: > + :exe "!ls " . shellescape(expand("%")) +< + A newline character ends {cmd}, what follows is + interpreted as a following ":" command. However, if + there is a backslash before the newline it is removed + and {cmd} continues. It doesn't matter how many + backslashes are before the newline, only one is + removed. + + On Unix the command normally runs in a non-interactive + shell. If you want an interactive shell to be used + (to use aliases) set 'shellcmdflag' to "-ic". + For Win32 also see |:!start|. + + After the command has been executed, the timestamp and + size of the current file is checked |timestamp|. + + Vim redraws the screen after the command is finished, + because it may have printed any text. This requires a + hit-enter prompt, so that you can read any messages. + To avoid this use: > + :silent !{cmd} +< The screen is not redrawn then, thus you have to use + CTRL-L or ":redraw!" if the command did display + something. + Also see |shell-window|. + + *:!!* +:!! Repeat last ":!{cmd}". + + *:ve* *:version* +:ve[rsion] Print the version number of the editor. If the + compiler used understands "__DATE__" the compilation + date is mentioned. Otherwise a fixed release-date is + shown. + The following lines contain information about which + features were enabled when Vim was compiled. When + there is a preceding '+', the feature is included, + when there is a '-' it is excluded. To change this, + you have to edit feature.h and recompile Vim. + To check for this in an expression, see |has()|. + Here is an overview of the features. + The first column shows the smallest version in which + they are included: + T tiny (always) + S small + N normal + B big + H huge + m manually enabled or depends on other features + (none) system dependent + Thus if a feature is marked with "N", it is included + in the normal, big and huge versions of Vim. + + *+feature-list* + *+acl* |ACL| support included + *+ARP* Amiga only: ARP support included +B *+arabic* |Arabic| language support +T *+autocmd* |:autocmd|, automatic commands +H *+autoservername* Automatically enable |clientserver| +m *+balloon_eval* |balloon-eval| support in the GUI.

The messages which + are the output of commands are written to that file, + until redirection ends. The messages are also still + shown on the screen.

If the variable + exists, then it is initialized to an empty string. + The variable will remain empty until redirection ends. + Only string variables can be used. After the + redirection starts, if the variable is removed or + locked or the variable type is changed, then further + command output messages will cause errors. {not in Vi} + To get the output of one command the |execute()| + function can be used. + +:redi[r] =>> {var} Append messages to an existing variable.

For example, to list only xml files: > + :filter /\.xml$/ oldfiles +< If the [!] is given, restrict the output of {command} + to lines that do NOT match {pat}. + + {pat} is a Vim search pattern. Instead of enclosing + it in / any non-ID character (see |'isident'|) can be + used, so long as it does not appear in {pat}. Without + the enclosing character the pattern cannot include the + bar character. + + The pattern is matched against the relevant part of + the output, not necessarily the whole line. Only some + commands support filtering, try it out to check if it + works. Some of the commands that support filtering: + |:#| - filter whole line + |:command| - filter by command name + |:files| - filter by file name + |:highlight| - filter by highlight group + |:jumps| - filter by file name + |:let| - filter by variable name + |:list| - filter whole line + |:llist| - filter by file name or module name + |:oldfiles| - filter by file name + |:clist| - filter by file name or module name + |:set| - filter by variable name + + Only normal messages are filtered, error messages are + not. + + *:sil* *:silent* *:silent!* +:sil[ent][!] {command} Execute {command} silently. Normal messages will not + be given or added to the message history. + When [!] is added, error messages will also be + skipped, and commands and mappings will not be aborted + when an error is detected. |v:errmsg| is still set. + When [!] is not used, an error message will cause + further messages to be displayed normally. + Redirection, started with |:redir|, will continue as + usual, although there might be small differences. + This will allow redirecting the output of a command + without seeing it on the screen. Example: > + :redir >/tmp/foobar + :silent g/Aap/p + :redir END +< To execute a Normal mode command silently, use the + |:normal| command. For example, to search for a + string without messages: > + :silent exe "normal /path\<CR>" +< ":silent!" is useful to execute a command that may + fail, but the failure is to be ignored. Example: > + :let v:errmsg = "" + :silent! /^begin + :if v:errmsg != "" + : ... pattern was not found +< ":silent" will also avoid the hit-enter prompt. When + using this for an external command, this may cause the + screen to be messed up. Use |CTRL-L| to clean it up + then. + ":silent menu ..." defines a menu that will not echo a + Command-line command. The command will still produce + messages though. Use ":silent" in the command itself + to avoid that: ":silent menu .... :silent command". + + *:uns* *:unsilent* +:uns[ilent] {command} Execute {command} not silently. Only makes a + difference when |:silent| was used to get to this + command. + Use this for giving a message even when |:silent| was + used. In this example |:silent| is used to avoid the + message about reading the file and |:unsilent| to be + able to list the first line of each file. > + :silent argdo unsilent echo expand('%') . ": " . getline(1) +< + + *:verb* *:verbose* +:[count]verb[ose] {command} + Execute {command} with 'verbose' set to [count]. If + [count] is omitted one is used. ":0verbose" can be + used to set 'verbose' to zero. + The additional use of ":silent" makes messages + generated but not displayed. + The combination of ":silent" and ":verbose" can be + used to generate messages and check them with + |v:statusmsg| and friends. For example: > + :let v:statusmsg = "" + :silent verbose runtime foobar.vim + :if v:statusmsg != "" + : " foobar.vim could not be found + :endif +< When concatenating another command, the ":verbose" + only applies to the first one: > + :4verbose set verbose | set verbose +< verbose=4 ~ + verbose=0 ~ + For logging verbose messages in a file use the + 'verbosefile' option. + + *:verbose-cmd* +When 'verbose' is non-zero, listing the value of a Vim option or a key map or +an abbreviation or a user-defined function or a command or a highlight group +or an autocommand will also display where it was last defined. If it was +defined manually then there will be no "Last set" message. When it was +defined while executing a function, user command or autocommand, the script in +which it was defined is reported. +{not available when compiled without the |+eval| feature} + + *K* +K Run a program to lookup the keyword under the + cursor. The name of the program is given with the + 'keywordprg' (kp) option (default is "man"). The + keyword is formed of letters, numbers and the + characters in 'iskeyword'. The keyword under or + right of the cursor is used. The same can be done + with the command > + :!{program} {keyword} +< There is an example of a program to use in the tools + directory of Vim. It is called "ref" and does a + simple spelling check. + Special cases: + - If 'keywordprg' begins with ":" it is invoked as + a Vim Ex command with [count]. + - If 'keywordprg' is empty, the ":help" command is + used. It's a good idea to include more characters + in 'iskeyword' then, to be able to find more help. + - When 'keywordprg' is equal to "man" or starts with + ":", a [count] before "K" is inserted after + keywordprg and before the keyword.

Using Vim like less or more *less* + +If you use the less or more program to view a file, you don't get syntax +highlighting. Thus you would like to use Vim instead. You can do this by +using the shell script "$VIMRUNTIME/macros/less.sh". + +This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim". It sets +up mappings to simulate the commands that less supports. Otherwise, you can +still use the Vim commands. + +This isn't perfect. For example, when viewing a short file Vim will still use +the whole screen. But it works good enough for most uses, and you get syntax +highlighting. + +The "h" key will give you a short overview of the available commands. + +If you want to set options differently when using less, define the +LessInitFunc in your vimrc, for example: > + + func LessInitFunc() + set nocursorcolumn nocursorline + endfunc +< + + vim:tw=78:ts=8:noet:ft=help:norl: |
