*various.txt* For Vim version 6.0. Last change: 2001 Sep 15 VIM REFERENCE MANUAL by Bram Moolenaar Various commands *various* 1. Various commands |various-cmds| 2. Online help |online-help| 3. Printing |printing| 4. Using Vim like less or more |less| ============================================================================== 1. Various commands *various-cmds* *CTRL-L* CTRL-L Clear and redraw the screen (later). *: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. *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. 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 Mnemonic: Get Ascii value. {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. Example of a character with three composing characters: > e0 b8 81 + e0 b8 b9 + e0 b9 89 < {not in Vi} *:p* *:pr* *:print* :[range]p[rint] Print [range] lines (default current line). Note: If you are looking for a way to print your text file, you need an external program for that. In the GUI you can use the File.Print menu entry. (For printing on paper see |:hardcopy|) :[range]p[rint] {count} Print {count} lines, starting with [range] (default current line |cmdline-ranges|). *:P* *:Print* :[range]P[rint] [count] Just as ":print". Was apparently added to Vi for people that keep the shift key pressed too long... *:l* *:list* :[range]l[ist] [count] Same as :print, but display unprintable characters with '^'. *:nu* *:number* :[range]nu[mber] [count] Same as :print, but precede each line with its line number. (See also 'highlight' option). *:#* :[range]# [count] synonym for :number. *: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; otherwise, the current window size is used. :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 location ~ ---- ---------- --------- ------------ + 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 src fwd = 1/2 src 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} *:=* := Print the cursor line number. :{range}= Prints the last line number in {range}. :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} is executed like it is typed. For undo all commands are undone together. If the [!] is given, mappings will not be used. {commands} should be a complete command. If {commands} does not finish a command, the last one will be aborted as if <Esc> was typed. The display isn't updated while doing this. This implies that an insert command must be completed (to start Insert mode, see |:startinsert|). A ":" command must be completed as well. 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'. When this command is called from a non-remappable mapping |:noremap|, the argument can be mapped anyway. An alternative is to use |:execute|, which uses an expression as argument. This allows the use of printable characters. Example: > :exe "normal \<c-w>\<c-w>" < {not in Vi, of course} Not available when |+ex_extra| feature was disabled at compile time. :{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} Not available when |+ex_extra| feature was disabled at compile time. *: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 ! \!". After the command has been executed, the timestamp of the current file is checked |timestamp|. There cannot be a '|' in {cmd}, see |:bar|. 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|. 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 S small N normal B big H huge m manually enabled (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* *+ARP* Amiga only: ARP support included N *+autocmd* |:autocmd|, automatic commands m *+balloon_eval* |balloon-eval| support N *+browse* |:browse| command N *+builtin_terms* some terminals builtin |builtin-terms| B *++builtin_terms* maximal terminals builtin |builtin-terms| N *+byte_offset* support for 'o' flag in 'statusline' option, "go" and ":goto" commands.

This was previously used to check the version number of a .vimrc file. It was removed, because you can now use the ":if" command for version-dependent behavior. {not in Vi} *:redi* *:redir* :redi[r][!] > {file} Redirect messages to file {file}. 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. When [!] is included, an existing file is overwritten. When [!] is omitted, and {file} exists, this command fails. To stop the messages and commands from being echoed to the screen, put the commands in a function and call it with ":silent call Function()". {not in Vi} :redi[r] >> {file} Redirect messages to file {file}. Append if {file} already exists. {not in Vi} :redi[r] @{a-zA-Z} Redirect messages to register {a-z}. Append to the contents of the register if its name is given uppercase {A-Z}. {not in Vi} :redi[r] @* Redirect messages to the clipboard. {not in Vi} :redi[r] @" Redirect messages to the unnamed register. {not in Vi} :redi[r] END End redirecting messages. {not in Vi} *:sil* *:silent* :sil[ent][!] {command} Execute {command} silently. Normal messages will not be given. 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". *:verb* *:verbose* :[count]verb[ose] {command} Execute {command} with 'verbose' set to [count]. If [count] is omitted one is used. 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 ~ *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' 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", a count before "K" is inserted after the "man" command and before the keyword. For example, using "2K" while the cursor is on "mkdir", results in: > !man 2 mkdir < - When 'keywordprg' is equal to "man -s", a count before "K" is inserted after the "-s". If there is no count, the "-s" is removed. {not in Vi} *v_K* {Visual}K Like "K", but use the visually highlighted text for the keyword. Only works when the highlighted text is not more than one line. {not in Vi} [N]gs *gs* *:sl* *:sleep* :[N]sl[eep] [N] [m] Do nothing for [N] seconds. When [m] is included, sleep for [N] milliseconds. The count for "gs" always uses seconds. The default is one second. > :sleep "sleep for one second :5sleep "sleep for five seconds :sleep 100m "sleep for a hundred milliseconds 10gs "sleep for ten seconds < Can be interrupted with CTRL-C (CTRL-Break on MS-DOS). "gs" stands for "goto sleep". While sleeping the cursor is positioned in the text (if visible). {not in Vi} *g_CTRL-A* g CTRL-A Only when Vim was compiled with MEM_PROFILING defined (which is very rare): print memory usage statistics. Only useful for debugging Vim. ============================================================================== 2. Online help *online-help* *help* *<Help>* *:h* *:help* *<F1>* *i_<F1>* *i_<Help>* <Help> or :h[elp] Open a window and display the help file in read-only mode. If there is a help window open already, use that one. Otherwise, if the current window uses the full width of the screen or is at least 80 characters wide, the help window will appear just above the current window. Otherwise the new window is put at the very top. {not in Vi} *{subject}* *E149* :h[elp] {subject} Like ":help", additionally jump to the tag {subject}. {subject} can include wildcards like "*", "?" and "[a-z]": :help z? jump to help for any "z" command :help z. jump to the help for "z." If there is no full match for the pattern, or there are several matches, the "best" match will be used. A sophisticated algorithm is used to decide which match is better than another one. These items are considered in the computation: - A match with same case is much better than a match with different case. - A match that starts after a non-alphanumeric character is better than a match in the middle of a word. - A match at or near the beginning of the tag is better than a match further on. - The more alphanumeric characters match, the better. - The shorter the length of the match, the better. Note that the longer the {subject} you give, the less matches will be found. You can get an idea how this all works by using commandline completion (type CTRL-D after ":help subject"). If there are several matches, you can have them listed by hitting CTRL-D. Example: > :help cont<Ctrl-D> < To use a regexp |pattern|, first do ":help" and then use ":tag {pattern}" in the help window. The ":tnext" command can then be used to jump to other matches, "tselect" to list matches and choose one. > :help index| :tse z. < This command can be followed by '|' and another command, but you don't need to escape the '|' inside a help command. So these both work: > :help | :help k| only < Note that a space before the '|' is seen as part of the ":help" argument. You can also use <LF> or <CR> to separate the help command from a following command. You need to type CTRL-V first to insert the <LF> or <CR>. Example: > :help so<C-V><CR>only < {not in Vi} When no argument is given the file given with the 'helpfile' option will be opened. Otherwise the specified tag is searched for in all "doc/tags" files in the directories specified in the 'runtimepath' option. The initial height of the help window can be set with the 'helpheight' option (default 20). Jump to specific subjects by using tags. This can be done in two ways: - Use the "CTRL-]" command while standing on the name of a command or option. This only works when the tag is a keyword. "<C-Leftmouse>" and "g<LeftMouse>" work just like "CTRL-]". - use the ":ta {subject}" command. This also works with non-keyword characters. Use CTRL-T or CTRL-O to jump back. Use ":q" to close the help window. If there are several matches for an item you are looking for, this is how you can jump to each one of them: 1. open a help window 2. Use the ":tag" command with a slash prepended to the tag. E.g.: > :tag /min 3. Use ":tnext" to jump to the next matching tag. It is possible to add help files for plugins and other items. You don't need to change the distributed help files for that. See |add-local-help| To write a local help file, see |write-local-help|. Note that the title lines from the local help files are automagically added to the "LOCAL ADDITIONS" section in the "help.txt" help file. This is done when viewing the file in Vim, the file itself is not changed. It is done by going through all help files and obtaining the first line of each file. The files in $VIMRUNTIME/doc are skipped. *help-xterm-window* If you want to have the help in another xterm window, you could use this command: :!xterm -e vim +help & *:helpfind* *:helpf* :helpf[ind] Like |:help|, but use a dialog to enter the argument. Only for backwards compatibilty. It now executes the ToolBar.HelpFind menu entry instead of using a builtin dialog. {only when compiled with |+GUI_GTK|} *:helpt* *:helptags* *E154* *E150* *E151* *E152* *E153* :helpt[ags] {dir} Generate the help tags file for directory {dir}. All "*.txt" files in the directory are scanned for a help tag definition in between stars. The generated tags file is sorted. When there are duplicates an error message is given. An existing tags file is silently overwritten. ============================================================================== 3. Printing *printing* On MS-Windows Vim can print your text on any installed printer. On other systems a PostScript file is produced. This can be directly sent to a PostScript printer. For other printers a program like ghostscript needs to be used. {not in Vi} {only available when compiled with |+printer| feature} *:ha* *:hardcopy* *E237* *E238* *E324* :[range]ha[rdcopy][!] [arguments] Send [range] lines (default whole file) to the printer. On MS-Windows a dialog is displayed to allow selection of printer, paper size etc. To skip the dialog, use the [!]. In this case the printer defined by 'printdevice' is used, or, if 'printdevice' is empty, the system default printer. For systems other than MS-Windows, PostScript is written in a temp file and 'printexpr' is used to actually print it. Then [arguments] can be used by 'printexpr' through |v:cmdarg|. Otherwise [arguments] is ignored. 'printoptions' can be used to specify paper size, duplex, etc. :[range]ha[rdcopy][!] >{filename} As above, but write the resulting PostScript in file {filename}. Careful: An existing file is silently overwritten. {only available when compiled with the |+postscript| feature} On MS-Windows use the "print to file" feature of the printer driver. Progress is displayed during printing as a page number and a percentage. To abort printing use the interrupt key (CTRL-C or, on MS-systems, CTRL-Break). Printer output is controlled by the 'printfont' and 'printoptions' options. 'printheader' specifies the format of a page header. The printed file is always limited to the selected margins, irrespective of the current window's 'wrap' or 'linebreak' settings. The "wrap" item in 'printoptions' can be used to switch wrapping off. The current highlighting colors are used in the printout, with the following considerations: 1) The normal background is always rendered as white (i.e. blank paper.) 2) White text or the default foreground is rendered as black, so that it shows up! 3) If 'background' is "dark", then the colours are darkened to compensate for the fact that otherwise they would be too bright to show up clearly on white paper. 3.1 PostScript Printing *E455* *E456* *E457* Provided you have enough disk space there should be no problems generating a PostScript file. You need to have the runtime files correctly installed (if you can find the help files, they probably are). There are currently a number of limitations with PostScript printing: - 'printfont' - The font name is ignored (the Courier family is always used - it should be available on all PostScript printers) but the font size is used. - 'printoptions' - The duplex setting is used when generating PostScript output, but it is up to the printer to take notice of the setting. If the printer does not support duplex printing then it should be silently ignored. Some printers, however, don't print at all. - 8-bit and Multi-byte support - There is limited support for 8-bit character set encodings. It is based on the Latin-1 encoding, modified for the host platform so that what is printed should match what VIM displays on screen. There is no support for multi-byte character sets - the characters are replaced with spaces. 3.2 PostScript Printing Troubleshooting Usually the only sign of a problem when printing with PostScript is that your printout does not appear. If you are lucky you may get a printed page that tells you the PostScript operator that generated the error that prevented the print job completing. There are a number of possible causes as to why the printing may have failed: - Paper size. Some PostScript printers will abort printing a file if they do not support the requested paper size. By default VIM uses A4 paper. Find out what size paper your printer normally uses and set the appropriate paper size with 'printoptions'. If you cannot find the name of the paper used, measure a sheet and compare it with the table of supported paper sizes listed for 'printoptions', using the paper that is closest in both width AND height. Note: The dimensions of actual paper may vary slightly from the ones listed. If there is no paper listed close enough, then you may want to try psresize from PSUtils, discussed below. - Two-sided printing (duplex). Normally a PostScript printer that does not support two-sided printing will ignore any request to do it. However, some printers may abort the job altogether. Try printing with duplex turned off. Note: Duplex prints can be achieved manually using PS utils - see below. - Collated printing. As with Duplex printing, most PostScript printers that do not support collating printouts will ignore a request to do so. Some may not. Try printing with collation turned off. - Syntax highlighting. Some print management code may prevent the generated PostScript file from being printed on a black and white printer when syntax highlighting is turned on, even if solid black is the only color used. Try printing with syntax highlighting turned off. A safe printoptions setting to try is: > :set printoptions=paper:A4,duplex:off,collate:n,syntax:n Replace "A4" with the paper size that best matches your printer paper. 3.3 PostScript Utilities 3.3.1 Ghostscript Ghostscript is a PostScript and PDF interpreter that can be used to display and print on non-PostScript printers PostScript and PDF files. It can also generate PDF files from PostScript. Ghostscript will run on a wide variety of platforms. There are three available versions: - AFPL Ghostscript (formerly Aladdin Ghostscript) which is free for non-commercial use. It can be obtained from: http://www.cs.wisc.edu/~ghost/ - GNU Ghostscript which is available under the GNU General Public License. It can be obtained from: ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/gnu/ - A commercial version for inclusion in commercial products. Additional information on Ghostscript can also be found at: http://www.ghostscript.com/ Support for a number of non PostScript printers is provided in the distribution as standard, but if you cannot find support for your printer check the Ghostscript site for other printers not included by default. 3.3.2 Ghostscript Previewers. The interface to Ghostscript is very primitive so a number of graphical front ends have been created. These allow easier PostScript file selection, previewing at different zoom levels, and printing. Check supplied documentation for full details. X11 - Ghostview. Obtainable from: http://www.cs.wisc.edu/~ghost/gv/ - gv. Derived from Ghostview. Obtainable from: http://wwwthep.physik.uni-mainz.de/~plass/gv/ Copies (possibly not the most recent) can be found at: http://www.cs.wisc.edu/~ghost/gv/ OpenVMS - gv-vms. A port of gv to OpenVMS. Obtainable from: ftp://axp.psl.ku.dk/decwindows/xaw3d/ ftp://ftp.wku.edu/vms/fileserv/x11kit.zip Windows and OS/2 - GSview. Obtainable from: http://www.cs.wisc.edu/~ghost/gsview/ DOS - ps_view.

Binary distributions are available for many platforms, as well as the full source. PSUtils can be found at: http://www.dcs.ed.ac.uk/home/ajcd/psutils/ The utilities of interest include: - psnup. Convert PS files for N-up printing. - psselect. Select page range and order of printing. - psresize. Change the page size. - psbook. Reorder and lay out pages ready for making a book. The output of one program can be used as the input to the next, allowing for complex print document creation. N-UP PRINTING The psnup utility takes an existing PostScript file generated from VIM and convert it to an n-up version. The simplest way to create a 2-up printout is to first create a PostScript file with: > :hardcopy > test.ps Then on your command line execute: > psnup -n 2 test.ps final.ps Note: You may get warnings from some Ghostscript previewers for files produced by psnup - these may safely be ignored. Finally print the file final.ps to your PostScript printer with your platform's print command. (You will need to delete the two PostScript files afterwards yourself.) 'printexpr' could be modified to perform this extra step before printing. ALTERNATE DUPLEX PRINTING It is possible to achieve a poor man's version of duplex printing using the PS utility psselect. This utility has options -e and -o for printing just the even or odd pages of a PS file respectively. First generate a PS file with the 'hardcopy' command, then generate a new files with all the odd and even numbered pages with: > psselect -o test.ps odd.ps psselect -e test.ps even.ps Next print odd.ps with your platform's normal print command. Then take the print output, turn it over and place it back in the paper feeder. Now print even.ps with your platform's print command. All the even pages should now appear on the back of the odd pages. There a couple of points to bear in mind: 1. Position of the first page. If the first page is on top of the printout when printing the odd pages then you need to reverse the order that the odd pages are printed. This can be done with the -r option to psselect. This will ensure page 2 is printed on the back of page 1. Note: it is better to reverse the odd numbered pages rather than the even numbered in case there are an odd number of pages in the original PS file. 2. Paper flipping. When turning over the paper with the odd pages printed on them you may have to either flip them horizontally (along the long edge) or vertically (along the short edge), as well as possibly rotating them 180 degrees. All this depends on the printer - it will be more obvious for desktop ink jets than for small office laser printers where the paper path is hidden from view. ============================================================================== 4. 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 comands. vim:tw=78:ts=8:ft=help:norl:
