13==============================================================================
141. Various commands *various-cmds*
15
16 *CTRL-L*
17CTRL-L Clear and redraw the screen (later).
18
19 *:redr* *:redraw*
20:redr[aw][!] Redraw the screen right now. When ! is included it is
21 cleared first.
22 Useful to update the screen halfway executing a script
23 or function. Also when halfway a mapping and
24 'lazyredraw' is set.
25
26 *:redraws* *:redrawstatus*
27:redraws[tatus][!] Redraw the status line of the current window. When !
28 is included all status lines are redrawn.
29 Useful to update the status line(s) when 'statusline'
30 includes an item that doesn't cause automatic
31 updating.
32
33 *N<Del>*
34<Del> When entering a number: Remove the last digit.
35 Note: if you like to use <BS> for this, add this
36 mapping to your .vimrc: >
37 :map CTRL-V <BS> CTRL-V <Del>
38< See |:fixdel| if your <Del> key does not do what you
39 want.
40
41:as[cii] or *ga* *:as* *:ascii*
42ga Print the ascii value of the character under the
43 cursor in decimal, hexadecimal and octal. For
44 example, when the cursor is on a 'R':
45 <R> 82, Hex 52, Octal 122 ~
46 When the character is a non-standard ASCII character,
47 but printable according to the 'isprint' option, the
48 non-printable version is also given. When the
49 character is larger than 127, the <M-x> form is also
50 printed. For example:
51 <~A> <M-^A> 129, Hex 81, Octal 201 ~
52 <p> <|~> <M-~> 254, Hex fe, Octal 376 ~
53 (where <p> is a special character)
54 The <Nul> character in a file is stored internally as
55 <NL>, but it will be shown as:
56 <^@> 0, Hex 00, Octal 000 ~
57 Mnemonic: Get Ascii value. {not in Vi}
58
59 *g8*
60g8 Print the hex values of the bytes used in the
61 character under the cursor, assuming it is in |UTF-8|
62 encoding. This also shows composing characters.
63 Example of a character with three composing
64 characters:
65 e0 b8 81 + e0 b8 b9 + e0 b9 89 ~
66 {not in Vi}
67
68 *:p* *:pr* *:print*
69:[range]p[rint] Print [range] lines (default current line).
70 Note: If you are looking for a way to print your text
71 file, you need an external program for that. In the
72 GUI you can use the File.Print menu entry.
73 (For printing on paper see |:hardcopy|)
74
75:[range]p[rint] {count}
76 Print {count} lines, starting with [range] (default
77 current line |cmdline-ranges|).
78
79 *:P* *:Print*
80:[range]P[rint] [count]
81 Just as ":print". Was apparently added to Vi for
82 people that keep the shift key pressed too long...
83
84 *:l* *:list*
85:[range]l[ist] [count]
86 Same as :print, but display unprintable characters
87 with '^'.
88
89 *:nu* *:number*
90:[range]nu[mber] [count]
91 Same as :print, but precede each line with its line
92 number. (See also 'highlight' option).
93
94 *:#*
95:[range]# [count] synonym for :number.
96
97 *:z* *E144*
98:{range}z[+-^.=]{count} Display several lines of text surrounding the line
99 specified with {range}, or around the current line
100 if there is no {range}. If there is a {count}, that's
101 how many lines you'll see; otherwise, the current
102 window size is used.
103
104 :z can be used either alone or followed by any of
105 several punctuation marks. These have the following
106 effect:
107
108 mark first line last line new location ~
109 ---- ---------- --------- ------------
110 + current line 1 scr forward 1 scr forward
111 - 1 scr back current line current line
112 ^ 2 scr back 1 scr back 1 scr back
113 . 1/2 scr back 1/2 scr fwd 1/2 src fwd
114 = 1/2 src back 1/2 scr fwd current line
115
116 Specifying no mark at all is the same as "+".
117 If the mark is "=", a line of dashes is printed
118 around the current line.
119
120:{range}z#[+-^.=]{count} *:z#*
121 Like ":z", but number the lines.
122 {not in all versions of Vi, not with these arguments}
123
124 *:=*
125:= Print the last line number.
126
127:{range}= Prints the last line number in {range}. For example,
128 this prints the current line number: >
129 :.=
130
131:norm[al][!] {commands} *:norm* *:normal*
132 Execute Normal mode commands {commands}. This makes
133 it possible to execute Normal mode commands typed on
134 the command-line. {commands} is executed like it is
135 typed. For undo all commands are undone together.
136 If the [!] is given, mappings will not be used.
137 {commands} should be a complete command. If
138 {commands} does not finish a command, the last one
139 will be aborted as if <Esc> or <C-C> was typed.
140 The display isn't updated while ":normal" is busy.
141 This implies that an insert command must be completed
142 (to start Insert mode, see |:startinsert|). A ":"
143 command must be completed as well.
144 {commands} cannot start with a space. Put a 1 (one)
145 before it, 1 space is one space.
146 The 'insertmode' option is ignored for {commands}.
147 This command cannot be followed by another command,
148 since any '|' is considered part of the command.
149 This command can be used recursively, but the depth is
150 limited by 'maxmapdepth'.
151 When this command is called from a non-remappable
152 mapping |:noremap|, the argument can be mapped anyway.
153 An alternative is to use |:execute|, which uses an
154 expression as argument. This allows the use of
155 printable characters. Example: >
156 :exe "normal \<c-w>\<c-w>"
157< {not in Vi, of course}
158 {not available when the |+ex_extra| feature was
159 disabled at compile time}
160
161:{range}norm[al][!] {commands} *:normal-range*
162 Execute Normal mode commands {commands} for each line
163 in the {range}. Before executing the {commands}, the
164 cursor is positioned in the first column of the range,
165 for each line. Otherwise it's the same as the
166 ":normal" command without a range.
167 {not in Vi}
168 Not available when |+ex_extra| feature was disabled at
169 compile time.
170
171 *:sh* *:shell* *E371*
172:sh[ell] This command starts a shell. When the shell exits
173 (after the "exit" command) you return to Vim. The
174 name for the shell command comes from 'shell' option.
175 *E360*
176 Note: This doesn't work when Vim on the Amiga was
177 started in QuickFix mode from a compiler, because the
178 compiler will have set stdin to a non-interactive
179 mode.
180
181 *:!cmd* *:!* *E34*
182:!{cmd} Execute {cmd} with the shell. See also the 'shell'
183 and 'shelltype' option.
184 Any '!' in {cmd} is replaced with the previous
185 external command (see also 'cpoptions'). But not when
186 there is a backslash before the '!', then that
187 backslash is removed. Example: ":!ls" followed by
188 ":!echo ! \! \\!" executes "echo ls ! \!".
189 After the command has been executed, the timestamp of
190 the current file is checked |timestamp|.
191 There cannot be a '|' in {cmd}, see |:bar|.
192 A newline character ends {cmd}, what follows is
193 interpreted as a following ":" command. However, if
194 there is a backslash before the newline it is removed
195 and {cmd} continues. It doesn't matter how many
196 backslashes are before the newline, only one is
197 removed.
198 On Unix the command normally runs in a non-interactive
199 shell. If you want an interactive shell to be used
200 (to use aliases) set 'shellcmdflag' to "-ic".
201 For Win32 also see |:!start|.
202 Vim redraws the screen after the command is finished,
203 because it may have printed any text. This requires a
204 hit-enter prompt, so that you can read any messages.
205 To avoid this use: >
206 :silent !{cmd}
207< The screen is not redrawn then, thus you have to use
208 CTRL-L or ":redraw!" if the command did display
209 something.
210 Also see |shell-window|.
211
212 *:!!*
213:!! Repeat last ":!{cmd}".
214
215 *:ve* *:version*
216:ve[rsion] Print the version number of the editor. If the
217 compiler used understands "__DATE__" the compilation
218 date is mentioned. Otherwise a fixed release-date is
219 shown.
220 The following lines contain information about which
221 features were enabled when Vim was compiled. When
222 there is a preceding '+', the feature is included,
223 when there is a '-' it is excluded. To change this,
224 you have to edit feature.h and recompile Vim.
225 To check for this in an expression, see |has()|.
226 Here is an overview of the features.
227 The first column shows the smallest version in which
228 they are included:
229 T tiny
230 S small
231 N normal
232 B big
233 H huge
234 m manually enabled or depends on other features
235 (none) system dependent
236 Thus if a feature is marked with "N", it is included
237 in the normal, big and huge versions of Vim.

358
359 */dyn* *E370* *E448*
360 To some of the features "/dyn" is added when the
361 feature is only available when the related library can
362 be dynamically loaded.
363
364:ve[rsion] {nr} Is now ignored. This was previously used to check the
365 version number of a .vimrc file. It was removed,
366 because you can now use the ":if" command for
367 version-dependent behavior. {not in Vi}
368
369 *:redi* *:redir*
370:redi[r][!] > {file} Redirect messages to file {file}. The messages which
371 are the output of commands are written to that file,
372 until redirection ends. The messages are also still
373 shown on the screen. When [!] is included, an
374 existing file is overwritten. When [!] is omitted,
375 and {file} exists, this command fails.
376 Only one ":redir" can be active at a time. Calls to
377 ":redir" will close any active redirection before
378 starting redirection to the new target.
379 To stop the messages and commands from being echoed to
380 the screen, put the commands in a function and call it
381 with ":silent call Function()".
382 {not in Vi}
383
384:redi[r] >> {file} Redirect messages to file {file}. Append if {file}
385 already exists. {not in Vi}
386
387:redi[r] @{a-zA-Z} Redirect messages to register {a-z}. Append to the
388 contents of the register if its name is given
389 uppercase {A-Z}. {not in Vi}
390
391:redi[r] @* Redirect messages to the clipboard. {not in Vi}
392
393:redi[r] @" Redirect messages to the unnamed register. {not in Vi}
394
395:redi[r] END End redirecting messages. {not in Vi}
396
397 *:sil* *:silent*
398:sil[ent][!] {command} Execute {command} silently. Normal messages will not
399 be given or added to the message history.
400 When [!] is added, error messages will also be
401 skipped, and commands and mappings will not be aborted
402 when an error is detected. |v:errmsg| is still set.
403 When [!] is not used, an error message will cause
404 further messages to be displayed normally.
405 Redirection, started with |:redir|, will continue as
406 usual, although there might be small differences.
407 This will allow redirecting the output of a command
408 without seeing it on the screen. Example: >
409 :redir >/tmp/foobar
410 :silent g/Aap/p
411 :redir END
412< To execute a Normal mode command silently, use the
413 |:normal| command. For example, to search for a
414 string without messages: >
415 :silent exe "normal /path\<CR>"
416< ":silent!" is useful to execute a command that may
417 fail, but the failure is to be ignored. Example: >
418 :let v:errmsg = ""
419 :silent! /^begin
420 :if v:errmsg != ""
421 : ... pattern was not found
422< ":silent" will also avoid the hit-enter prompt. When
423 using this for an external command, this may cause the
424 screen to be messed up. Use |CTRL-L| to clean it up
425 then.
426 ":silent menu ..." defines a menu that will not echo a
427 Command-line command. The command will still produce
428 messages though. Use ":silent" in the command itself
429 to avoid that: ":silent menu .... :silent command".
430
431 *:verb* *:verbose*
432:[count]verb[ose] {command}
433 Execute {command} with 'verbose' set to [count]. If
Bram Moolenaared203462004-06-16 11:19:22 +0000434 [count] is omitted one is used. ":0verbose" can be
435 used to set 'verbose' to zero.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000436 The additional use of ":silent" makes messages
437 generated but not displayed.
438 The combination of ":silent" and ":verbose" can be
439 used to generate messages and check them with
440 |v:statusmsg| and friends. For example: >
441 :let v:statusmsg = ""
442 :silent verbose runtime foobar.vim
443 :if v:statusmsg != ""
444 : " foobar.vim could not be found
445 :endif
446< When concatenating another command, the ":verbose"
447 only applies to the first one: >
448 :4verbose set verbose | set verbose
449< verbose=4 ~
450 verbose=0 ~
451
452 *K*
453K Run a program to lookup the keyword under the
454 cursor. The name of the program is given with the
455 'keywordprg' (kp) option (default is "man"). The
456 keyword is formed of letters, numbers and the
457 characters in 'iskeyword'. The keyword under or
458 right of the cursor is used. The same can be done
459 with the command >
460 :!{program} {keyword}
461< There is an example of a program to use in the tools
462 directory of Vim. It is called 'ref' and does a
463 simple spelling check.
464 Special cases:
465 - If 'keywordprg' is empty, the ":help" command is
466 used. It's a good idea to include more characters
467 in 'iskeyword' then, to be able to find more help.
468 - When 'keywordprg' is equal to "man", a count before
469 "K" is inserted after the "man" command and before
470 the keyword. For example, using "2K" while the
471 cursor is on "mkdir", results in: >
472 !man 2 mkdir
473< - When 'keywordprg' is equal to "man -s", a count
474 before "K" is inserted after the "-s". If there is
475 no count, the "-s" is removed.
476 {not in Vi}
477
478 *v_K*
479{Visual}K Like "K", but use the visually highlighted text for
480 the keyword. Only works when the highlighted text is
481 not more than one line. {not in Vi}
482
483[N]gs *gs* *:sl* *:sleep*

5022. Online help *online-help*
503
504 *help* *<Help>* *:h* *:help* *<F1>* *i_<F1>* *i_<Help>*
505<Help> or
506:h[elp] Open a window and display the help file in read-only
507 mode. If there is a help window open already, use
508 that one. Otherwise, if the current window uses the
509 full width of the screen or is at least 80 characters
510 wide, the help window will appear just above the
511 current window. Otherwise the new window is put at
512 the very top.
513 The 'helplang' option is used to select a language, if
514 the main help file is available in several languages.
515 {not in Vi}
516
517 *{subject}* *E149* *E661*
518:h[elp] {subject} Like ":help", additionally jump to the tag {subject}.
519 {subject} can include wildcards like "*", "?" and
520 "[a-z]":
521 :help z? jump to help for any "z" command
522 :help z. jump to the help for "z."
523 If there is no full match for the pattern, or there
524 are several matches, the "best" match will be used.
525 A sophisticated algorithm is used to decide which
526 match is better than another one. These items are
527 considered in the computation:
528 - A match with same case is much better than a match
529 with different case.
530 - A match that starts after a non-alphanumeric
531 character is better than a match in the middle of a
532 word.
533 - A match at or near the beginning of the tag is
534 better than a match further on.
535 - The more alphanumeric characters match, the better.
536 - The shorter the length of the match, the better.
537
538 The 'helplang' option is used to select a language, if
539 the {subject} is available in several languages.
540 To find a tag in a specific language, append "@ab",
541 where "ab" is the two-letter language code. See
542 |help-translated|.
543
544 Note that the longer the {subject} you give, the less
545 matches will be found. You can get an idea how this
546 all works by using commandline completion (type CTRL-D
547 after ":help subject").
548 If there are several matches, you can have them listed
549 by hitting CTRL-D. Example: >
550 :help cont<Ctrl-D>
551< To use a regexp |pattern|, first do ":help" and then
552 use ":tag {pattern}" in the help window. The
553 ":tnext" command can then be used to jump to other
554 matches, "tselect" to list matches and choose one. >
555 :help index| :tse z.
556< This command can be followed by '|' and another
557 command, but you don't need to escape the '|' inside a
558 help command. So these both work: >
559 :help |
560 :help k| only
561< Note that a space before the '|' is seen as part of
562 the ":help" argument.
563 You can also use <LF> or <CR> to separate the help
564 command from a following command. You need to type
565 CTRL-V first to insert the <LF> or <CR>. Example: >
566 :help so<C-V><CR>only
567< {not in Vi}
568
569:h[elp]! [subject] Like ":help", but in non-English help files prefer to
570 find a tag in a file with the same language as the
571 current file. See |help-translated|.
572
573 *:helpg* *:helpgrep*
Bram Moolenaar69a7cb42004-06-20 12:51:53 +0000574:helpg[rep] {pattern}[@xx]
Bram Moolenaar071d4272004-06-13 20:20:40 +0000575 Search all help text files and make a list of lines
576 in which {pattern} matches. Jumps to the first match.
Bram Moolenaar69a7cb42004-06-20 12:51:53 +0000577 The optional [@xx] specifies that only matches in the
578 "xx" language are to be found.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000579 You can navigate through the matches with the
580 |quickfix| commands, e.g., |:cnext| to jump to the
581 next one. Or use |:cwindow| to get the list of
582 matches in the quickfix window.
583 {pattern} is used as a Vim regexp |pattern|.
584 'ignorecase' is not used, add "\c" to ignore case.
585 Example for case sensitive search: >
586 :helpgrep Uganda
587< Example for case ignoring search: >
588 :helpgrep uganda\c
Bram Moolenaar69a7cb42004-06-20 12:51:53 +0000589< Example for searching in French help: >
590 :helpgrep backspace@fr
Bram Moolenaar071d4272004-06-13 20:20:40 +0000591< Cannot be followed by another command, everything is
592 used as part of the pattern. But you can use
593 |:execute| when needed.
594 Compressed help files will not be searched (Debian
595 compresses the help files).
596 {not in Vi}
597
Bram Moolenaarb5bf5b82004-12-24 14:35:23 +0000598 *:exu* *:exusage*
599:exu[sage] Show help on Ex commands. Added to simulate the Nvi
600 command. {not in Vi}
601
602 *:viu* *:viusage*
603:viu[sage] Show help on Normal mode commands. Added to simulate
604 the Nvi command. {not in Vi}
Bram Moolenaar071d4272004-06-13 20:20:40 +0000605
606When no argument is given to |:help| the file given with the 'helpfile' option
607will be opened. Otherwise the specified tag is searched for in all "doc/tags"
608files in the directories specified in the 'runtimepath' option.
609
610The initial height of the help window can be set with the 'helpheight' option
611(default 20).
612
613Jump to specific subjects by using tags. This can be done in two ways:
614- Use the "CTRL-]" command while standing on the name of a command or option.
615 This only works when the tag is a keyword. "<C-Leftmouse>" and
616 "g<LeftMouse>" work just like "CTRL-]".
617- use the ":ta {subject}" command. This also works with non-keyword
618 characters.
619
620Use CTRL-T or CTRL-O to jump back.
621Use ":q" to close the help window.
622
623If there are several matches for an item you are looking for, this is how you
624can jump to each one of them:
6251. Open a help window
6262. Use the ":tag" command with a slash prepended to the tag. E.g.: >
627 :tag /min
6283. Use ":tnext" to jump to the next matching tag.
629
630It is possible to add help files for plugins and other items. You don't need
631to change the distributed help files for that. See |add-local-help|.
632
633To write a local help file, see |write-local-help|.
634
635Note that the title lines from the local help files are automagically added to
636the "LOCAL ADDITIONS" section in the "help.txt" help file |local-additions|.
637This is done when viewing the file in Vim, the file itself is not changed. It
638is done by going through all help files and obtaining the first line of each
639file. The files in $VIMRUNTIME/doc are skipped.
640
641 *help-xterm-window*
642If you want to have the help in another xterm window, you could use this
643command: >
644 :!xterm -e vim +help &
645<
646
647 *:helpfind* *:helpf*
648:helpf[ind] Like |:help|, but use a dialog to enter the argument.
649 Only for backwards compatibility. It now executes the
650 ToolBar.FindHelp menu entry instead of using a builtin
651 dialog. {only when compiled with |+GUI_GTK|}
652< {not in Vi}
653
654 *:helpt* *:helptags*
655 *E154* *E150* *E151* *E152* *E153* *E670*
656:helpt[ags] {dir} Generate the help tags file(s) for directory {dir}.
657 All "*.txt" and "*.??x" files in the directory are
658 scanned for a help tag definition in between stars.
659 The "*.??x" files are for translated docs, they
660 generate the "tags-??" file, see |help-translated|.
661 The generated tags files are sorted.
662 When there are duplicates an error message is given.
663 An existing tags file is silently overwritten.
664 To rebuild the help tags in the runtime directory
665 (requires write permission there): >
666 :helptags $VIMRUNTIME/doc
667< {not in Vi}
668
669
670TRANSLATED HELP *help-translated*
671
672It is possible to add translated help files, next to the original English help
673files. Vim will search for all help in "doc" directories in 'runtimepath'.
674This is only available when compiled with the |+multi_lang| feature.
675
676A set of translated help files consists of these files:
677
678 help.abx
679 howto.abx
680 ...
681 tags-ab
682
683"ab" is the two-letter language code. Thus for Italian the names are:
684
685 help.itx
686 howto.itx
687 ...
688 tags-it
689
690The 'helplang' option can be set to the preferred language(s). The default is
691set according to the environment. Vim will first try to find a matching tag
692in the preferred language(s). English is used when it cannot be found.
693
694To find a tag in a specific language, append "@ab" to a tag, where "ab" is the
695two-letter language code. Example: >
696 :he user-manual@it
697 :he user-manual@en
698The first one finds the Italian user manual, even when 'helplang' is empty.
699The second one finds the English user manual, even when 'helplang' is set to
700"it".
701
702When using command-line completion for the ":help" command, the "@en"
703extention is only shown when a tag exists for multiple languages. When the
704tag only exists for English "@en" is omitted.
705
706When using |CTRL-]| or ":help!" in a non-English help file Vim will try to
707find the tag in the same language. If not found then 'helplang' will be used
708to select a language.
709
710Help files must use latin1 or utf-8 encoding. Vim assumes the encoding is
711utf-8 when finding non-ASCII characters in the first line. Thus you must
712translate the header with "For Vim version".
713
714The same encoding must be used for the help files of one language in one
715directory. You can use a different encoding for different languages and use
716a different encoding for help files of the same language but in a different
717directory.
718
719Hints for translators:
720- Do not translate the tags. This makes it possible to use 'helplang' to
721 specify the preferred language. You may add new tags in your language.
722- When you do not translate a part of a file, add tags to the English version,
723 using the "tag@en" notation.
724- Make a package with all the files and the tags file available for download.
725 Users can drop it in one of the "doc" directories and start use it.
726 Report this to Bram, so that he can add a link on www.vim.org.
727- Use the |:helptags| command to generate the tags files. It will find all
728 languages in the specified directory.

730==============================================================================
Bram Moolenaar071d4272004-06-13 20:20:40 +00007314. Using Vim like less or more *less*
732
733If you use the less or more program to view a file, you don't get syntax
734highlighting. Thus you would like to use Vim instead. You can do this by
735using the shell script "$VIMRUNTIME/macros/less.sh".
736
737This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim". It sets
738up mappings to simulate the commands that less supports. Otherwise, you can
739still use the Vim commands.
740
741This isn't perfect. For example, when viewing a short file Vim will still use
742the whole screen. But it works good enough for most uses, and you get syntax
743highlighting.
744
745The "h" key will give you a short overview of the available commands.
