25 ============================================================================== | |
26 1. Introduction *autocmd-intro* | |
27 | |
22 | 28 You can specify commands to be executed automatically when reading or writing |
29 a file, when entering or leaving a buffer or window, and when exiting Vim. | |
30 For example, you can create an autocommand to set the 'cindent' option for | |
31 files matching *.c. You can also use autocommands to implement advanced | |
7 | 32 features, such as editing compressed files (see |gzip-example|). The usual |
33 place to put autocommands is in your .vimrc or .exrc file. | |
34 | |
13231 | 35 *E203* *E204* *E143* *E855* *E937* *E952* |
7 | 36 WARNING: Using autocommands is very powerful, and may lead to unexpected side |
37 effects. Be careful not to destroy your text. | |
38 - It's a good idea to do some testing on an expendable copy of a file first. | |
39 For example: If you use autocommands to decompress a file when starting to | |
40 edit it, make sure that the autocommands for compressing when writing work | |
41 correctly. | |
42 - Be prepared for an error halfway through (e.g., disk full). Vim will mostly | |
43 be able to undo the changes to the buffer, but you may have to clean up the | |
44 changes to other files by hand (e.g., compress a file that has been | |
45 decompressed). | |
46 - If the BufRead* events allow you to edit a compressed file, the FileRead* | |
47 events should do the same (this makes recovery possible in some rare cases). | |
48 It's a good idea to use the same autocommands for the File* and Buf* events | |
49 when possible. | |
50 | |
51 ============================================================================== | |
52 2. Defining autocommands *autocmd-define* | |
53 | |
54 *:au* *:autocmd* | |
55 :au[tocmd] [group] {event} {pat} [nested] {cmd} | |
56 Add {cmd} to the list of commands that Vim will | |
57 execute automatically on {event} for a file matching | |

7 | 79 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
80 arguments are not expanded when the autocommand is defined. These will be | |
81 expanded when the Event is recognized, and the {cmd} is executed. The only | |
82 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
83 > | |
84 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
85 | |
86 Here Vim expands <sfile> to the name of the file containing this line. | |

96 augroup END |
7 | 97 |
98 If you don't want to remove all autocommands, you can instead use a variable | |
99 to ensure that Vim includes the autocommands only once: > | |
100 | |
101 :if !exists("autocommands_loaded") | |
102 : let autocommands_loaded = 1 | |
103 : au ... | |
104 :endif | |
105 | |
106 When the [group] argument is not given, Vim uses the current group (as defined | |
107 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
108 that [group] must have been defined before. You cannot define a new group | |
109 with ":au group ..."; use ":augroup" for that. | |
110 | |
111 While testing autocommands, you might find the 'verbose' option to be useful: > | |
112 :set verbose=9 | |
113 This setting makes Vim echo the autocommands as it executes them. | |
114 | |
115 When defining an autocommand in a script, it will be able to call functions | |
116 local to the script and use mappings local to the script. When the event is | |
117 triggered and the command executed, it will run in the context of the script | |
118 it was defined in. This matters if |<SID>| is used in a command. | |
119 | |
1621 | 120 When executing the commands, the message from one command overwrites a |
7 | 121 previous message. This is different from when executing the commands |
122 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
123 prompt. When one command outputs two messages this can happen anyway. | |
124 | |
125 ============================================================================== | |
126 3. Removing autocommands *autocmd-remove* | |
127 | |
128 :au[tocmd]! [group] {event} {pat} [nested] {cmd} | |
129 Remove all autocommands associated with {event} and | |
130 {pat}, and add the command {cmd}. See | |
131 |autocmd-nested| for [nested]. | |
132 | |
133 :au[tocmd]! [group] {event} {pat} | |
134 Remove all autocommands associated with {event} and | |
135 {pat}. | |
136 | |
137 :au[tocmd]! [group] * {pat} | |
138 Remove all autocommands associated with {pat} for all | |
139 events. | |
140 | |
141 :au[tocmd]! [group] {event} | |
142 Remove ALL autocommands for {event}. | |

149 group, it breaks plugins, syntax highlighting, etc. |
7 | 150 |
151 When the [group] argument is not given, Vim uses the current group (as defined | |
152 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
153 | |
154 ============================================================================== | |
155 4. Listing autocommands *autocmd-list* | |
156 | |
157 :au[tocmd] [group] {event} {pat} | |
158 Show the autocommands associated with {event} and | |
159 {pat}. | |
160 | |
161 :au[tocmd] [group] * {pat} | |
162 Show the autocommands associated with {pat} for all | |
163 events. | |
164 | |
165 :au[tocmd] [group] {event} | |
166 Show all autocommands for {event}. | |
167 | |
168 :au[tocmd] [group] Show all autocommands. | |
169 | |
170 If you provide the [group] argument, Vim lists only the autocommands for | |
171 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
172 argument behavior differs from that for defining and removing autocommands. | |
173 | |
40 | 174 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
175 or <buffer=N>. See |autocmd-buflocal|. | |
176 | |
500 | 177 *:autocmd-verbose* |
178 When 'verbose' is non-zero, listing an autocommand will also display where it | |
179 was last defined. Example: > | |
180 | |
181 :verbose autocmd BufEnter | |
182 FileExplorer BufEnter | |
856 | 183 * call s:LocalBrowse(expand("<amatch>")) |
500 | 184 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
185 < | |
186 See |:verbose-cmd| for more information. | |
187 | |
7 | 188 ============================================================================== |
189 5. Events *autocmd-events* *E215* *E216* | |
190 | |
579 | 191 You can specify a comma-separated list of event names. No white space can be |
192 used in this list. The command applies to all the events in the list. | |
193 | |
194 For READING FILES there are four kinds of events possible: | |
195 BufNewFile starting to edit a non-existent file | |
196 BufReadPre BufReadPost starting to edit an existing file | |
197 FilterReadPre FilterReadPost read the temp file with filter output | |
198 FileReadPre FileReadPost any other file read | |
199 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
200 "Post" events are both triggered, before and after reading the file. | |
201 | |
202 Note that the autocommands for the *ReadPre events and all the Filter events | |
203 are not allowed to change the current buffer (you will get an error message if | |
204 this happens). This is to prevent the file to be read into the wrong buffer. | |
205 | |
206 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
207 and BufNewFile autocommands. But when the 'modified' option was set by the | |
208 autocommands, this doesn't happen. | |
209 | |
210 You can use the 'eventignore' option to ignore a number of events or all | |
211 events. | |
7 | 212 *autocommand-events* *{event}* |
213 Vim recognizes the following events. Vim ignores the case of event names | |
214 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
215 | |
579 | 216 First an overview by function with a short explanation. Then the list |

359 The alphabetical list of autocommand events: *autocmd-events-abc* | |
360 | |
361 *BufCreate* *BufAdd* | |
362 BufAdd or BufCreate Just after creating a new buffer which is | |
363 added to the buffer list, or adding a buffer | |
364 to the buffer list. | |
365 Also used just after a buffer in the buffer | |
366 list has been renamed. | |
367 The BufCreate event is for historic reasons. | |
368 NOTE: When this autocommand is executed, the | |
369 current buffer "%" may be different from the | |
370 buffer being created "<afile>". | |
371 *BufDelete* | |
372 BufDelete Before deleting a buffer from the buffer list. | |
373 The BufUnload may be called first (if the | |
374 buffer was loaded). | |
375 Also used just before a buffer in the buffer | |
376 list is renamed. | |
377 NOTE: When this autocommand is executed, the | |
378 current buffer "%" may be different from the | |
1621 | 379 buffer being deleted "<afile>" and "<abuf>". |
1919 | 380 Don't change to another buffer, it will cause |
381 problems. | |
579 | 382 *BufEnter* |
383 BufEnter After entering a buffer. Useful for setting | |
384 options for a file type. Also executed when | |
385 starting to edit a buffer, after the | |
386 BufReadPost autocommands. | |
387 *BufFilePost* | |
388 BufFilePost After changing the name of the current buffer | |
389 with the ":file" or ":saveas" command. | |
625 | 390 *BufFilePre* |
579 | 391 BufFilePre Before changing the name of the current buffer |
392 with the ":file" or ":saveas" command. | |
393 *BufHidden* | |
394 BufHidden Just after a buffer has become hidden. That | |
395 is, when there are no longer windows that show | |
396 the buffer, but the buffer is not unloaded or | |
397 deleted. Not used for ":qa" or ":q" when | |
398 exiting Vim. | |
399 NOTE: When this autocommand is executed, the | |
400 current buffer "%" may be different from the | |
401 buffer being unloaded "<afile>". | |
402 *BufLeave* | |
403 BufLeave Before leaving to another buffer. Also when | |
404 leaving or closing the current window and the | |
405 new current window is not for the same buffer. | |
406 Not used for ":qa" or ":q" when exiting Vim. | |
407 *BufNew* | |
408 BufNew Just after creating a new buffer. Also used | |
409 just after a buffer has been renamed. When | |
410 the buffer is added to the buffer list BufAdd | |
411 will be triggered too. | |
412 NOTE: When this autocommand is executed, the | |
413 current buffer "%" may be different from the | |
414 buffer being created "<afile>". | |
7 | 415 *BufNewFile* |
416 BufNewFile When starting to edit a file that doesn't | |
417 exist. Can be used to read in a skeleton | |
418 file. | |
419 *BufRead* *BufReadPost* | |
420 BufRead or BufReadPost When starting to edit a new buffer, after | |
421 reading the file into the buffer, before | |
422 executing the modelines. See |BufWinEnter| | |
423 for when you need to do something after | |
424 processing the modelines. | |
425 This does NOT work for ":r file". Not used | |
426 when the file doesn't exist. Also used after | |
427 successfully recovering a file. | |
3682 | 428 Also triggered for the filetypedetect group |
429 when executing ":filetype detect" and when | |
430 writing an unnamed buffer in a way that the | |
431 buffer gets a name. | |
625 | 432 *BufReadCmd* |
7 | 433 BufReadCmd Before starting to edit a new buffer. Should |
434 read the file into the buffer. |Cmd-event| | |
625 | 435 *BufReadPre* *E200* *E201* |

437 reading the file into the buffer. Not used | |
438 if the file doesn't exist. | |
439 *BufUnload* | |
440 BufUnload Before unloading a buffer. This is when the | |
441 text in the buffer is going to be freed. This | |
442 may be after a BufWritePost and before a | |
443 BufDelete. Also used for all buffers that are | |
444 loaded when Vim is going to exit. | |
445 NOTE: When this autocommand is executed, the | |
446 current buffer "%" may be different from the | |
447 buffer being unloaded "<afile>". | |

451 event is not triggered. |
579 | 452 *BufWinEnter* |
453 BufWinEnter After a buffer is displayed in a window. This | |
454 can be when the buffer is loaded (after | |
1621 | 455 processing the modelines) or when a hidden |
579 | 456 buffer is displayed in a window (and is no |
1621 | 457 longer hidden). |
458 Does not happen for |:split| without | |
459 arguments, since you keep editing the same | |
460 buffer, or ":split" with a file that's already | |
1668 | 461 open in a window, because it re-uses an |
462 existing buffer. But it does happen for a | |
463 ":split" with the name of the current buffer, | |
464 since it reloads that buffer. | |
579 | 465 *BufWinLeave* |
466 BufWinLeave Before a buffer is removed from a window. | |
467 Not when it's still visible in another window. | |
468 Also triggered when exiting. It's triggered | |
469 before BufUnload or BufHidden. | |
470 NOTE: When this autocommand is executed, the | |
471 current buffer "%" may be different from the | |
472 buffer being unloaded "<afile>". | |

474 event is not triggered. |
579 | 475 *BufWipeout* |
476 BufWipeout Before completely deleting a buffer. The | |
477 BufUnload and BufDelete events may be called | |
478 first (if the buffer was loaded and was in the | |
479 buffer list). Also used just before a buffer | |
480 is renamed (also when it's not in the buffer | |
481 list). | |
482 NOTE: When this autocommand is executed, the | |
483 current buffer "%" may be different from the | |
484 buffer being deleted "<afile>". | |
1919 | 485 Don't change to another buffer, it will cause |
486 problems. | |
7 | 487 *BufWrite* *BufWritePre* |
488 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
489 *BufWriteCmd* | |
490 BufWriteCmd Before writing the whole buffer to a file. | |
491 Should do the writing of the file and reset | |
39 | 492 'modified' if successful, unless '+' is in |
493 'cpo' and writing to another file |cpo-+|. | |
494 The buffer contents should not be changed. | |
3082 | 495 When the command resets 'modified' the undo |
496 information is adjusted to mark older undo | |
497 states as 'modified', like |:write| does. | |
39 | 498 |Cmd-event| |
579 | 499 *BufWritePost* |
500 BufWritePost After writing the whole buffer to a file | |
501 (should undo the commands for BufWritePre). | |
6154 | 502 *CmdUndefined* |
503 CmdUndefined When a user command is used but it isn't | |
504 defined. Useful for defining a command only | |
505 when it's used. The pattern is matched | |
506 against the command name. Both <amatch> and | |
507 <afile> are set to the name of the command. | |
508 NOTE: Autocompletion won't work until the | |
509 command is defined. An alternative is to | |
510 always define the user command and have it | |
511 invoke an autoloaded function. See |autoload|. | |

555 name of the actual file where this option was | |
556 set, and <amatch> for the new colorscheme | |
557 name. | |
558 | |
661 | 559 |
3682 | 560 *CompleteDone* |
561 CompleteDone After Insert mode completion is done. Either | |
562 when something was completed or abandoning | |
563 completion. |ins-completion| | |
6909 | 564 The |v:completed_item| variable contains |
565 information about the completed item. | |
3682 | 566 |
579 | 567 *CursorHold* |
568 CursorHold When the user doesn't press a key for the time | |
569 specified with 'updatetime'. Not re-triggered | |
570 until the user has pressed a key (i.e. doesn't | |
571 fire every 'updatetime' ms if you leave Vim to | |
572 make some coffee. :) See |CursorHold-example| | |
573 for previewing tags. | |
574 This event is only triggered in Normal mode. | |
1154 | 575 It is not triggered when waiting for a command |
576 argument to be typed, or a movement after an | |
577 operator. | |
610 | 578 While recording the CursorHold event is not |
579 triggered. |q| | |
6259 | 580 *<CursorHold>* |
581 Internally the autocommand is triggered by the | |
582 <CursorHold> key. In an expression mapping | |
583 |getchar()| may see this character. | |
584 | |
579 | 585 Note: Interactive commands cannot be used for |
586 this event. There is no hit-enter prompt, | |
587 the screen is updated directly (when needed). | |
588 Note: In the future there will probably be | |
589 another option to set the time. | |
590 Hint: to force an update of the status lines | |
591 use: > | |
592 :let &ro = &ro | |
593 < {only on Amiga, Unix, Win32, MSDOS and all GUI | |
594 versions} | |
661 | 595 *CursorHoldI* |
596 CursorHoldI Just like CursorHold, but in Insert mode. | |

7 | 660 *FileChangedShell* |
661 FileChangedShell When Vim notices that the modification time of | |
662 a file has changed since editing started. | |
663 Also when the file attributes of the file | |
5908 | 664 change or when the size of the file changes. |
665 |timestamp| | |
7 | 666 Mostly triggered after executing a shell |
667 command, but also with a |:checktime| command | |
11473 | 668 or when gvim regains input focus. |
7 | 669 This autocommand is triggered for each changed |
670 file. It is not used when 'autoread' is set | |
671 and the buffer was not changed. If a | |
672 FileChangedShell autocommand is present the | |
673 warning message and prompt is not given. | |
179 | 674 The |v:fcs_reason| variable is set to indicate |
675 what happened and |v:fcs_choice| can be used | |
676 to tell Vim what to do next. | |
7 | 677 NOTE: When this autocommand is executed, the |
678 current buffer "%" may be different from the | |
11347 | 679 buffer that was changed, which is in "<afile>". |
7 | 680 NOTE: The commands must not change the current |
681 buffer, jump to another buffer or delete a | |

682 buffer. *E246* *E811* |
7 | 683 NOTE: This event never nests, to avoid an |
684 endless loop. This means that while executing | |
685 commands for the FileChangedShell event no | |
686 other FileChangedShell event will be | |
687 triggered. | |
766 | 688 *FileChangedShellPost* |
689 FileChangedShellPost After handling a file that was changed outside | |
690 of Vim. Can be used to update the statusline. | |
579 | 691 *FileEncoding* |
692 FileEncoding Obsolete. It still works and is equivalent | |
693 to |EncodingChanged|. | |
694 *FileReadCmd* | |

696 Should do the reading of the file. |Cmd-event| | |
697 *FileReadPost* | |
698 FileReadPost After reading a file with a ":read" command. | |
699 Note that Vim sets the '[ and '] marks to the | |
700 first and last line of the read. This can be | |
701 used to operate on the lines just read. | |
702 *FileReadPre* | |
703 FileReadPre Before reading a file with a ":read" command. | |

726 FilterReadPost After reading a file from a filter command. | |
727 Vim checks the pattern against the name of | |
728 the current buffer as with FilterReadPre. | |
729 Not triggered when 'shelltemp' is off. | |
730 *FilterReadPre* *E135* | |
731 FilterReadPre Before reading a file from a filter command. | |

761 FuncUndefined When a user function is used but it isn't | |
762 defined. Useful for defining a function only | |
1154 | 763 when it's used. The pattern is matched |
764 against the function name. Both <amatch> and | |
765 <afile> are set to the name of the function. | |
6154 | 766 NOTE: When writing Vim scripts a better |
767 alternative is to use an autoloaded function. | |
161 | 768 See |autoload-functions|. |
579 | 769 *GUIEnter* |
770 GUIEnter After starting the GUI successfully, and after | |
771 opening the window. It is triggered before | |
772 VimEnter when using gvim. Can be used to | |
773 position the window from a .gvimrc file: > | |
774 :autocmd GUIEnter * winpos 100 50 | |
1154 | 775 < *GUIFailed* |
776 GUIFailed After starting the GUI failed. Vim may | |
777 continue to run in the terminal, if possible | |
778 (only on Unix and alikes, when connecting the | |
779 X server fails). You may want to quit Vim: > | |
780 :autocmd GUIFailed * qall | |
579 | 781 < *InsertChange* |

786 anything else that the user does not expect. | |
2845 | 787 *InsertCharPre* |
788 InsertCharPre When a character is typed in Insert mode, | |
789 before inserting the char. | |
790 The |v:char| variable indicates the char typed | |
791 and can be changed during the event to insert | |
792 a different character. When |v:char| is set | |
793 to more than one character this text is | |
794 inserted literally. | |
795 It is not allowed to change the text |textlock|. | |
796 The event is not triggered when 'paste' is | |
13437 | 797 set. {only with the +eval feature} |
579 | 798 *InsertEnter* |
1154 | 799 InsertEnter Just before starting Insert mode. Also for |
800 Replace mode and Virtual Replace mode. The | |
579 | 801 |v:insertmode| variable indicates the mode. |
4448 | 802 Be careful not to do anything else that the |
803 user does not expect. | |
804 The cursor is restored afterwards. If you do | |
805 not want that set |v:char| to a non-empty | |
806 string. | |
579 | 807 *InsertLeave* |
808 InsertLeave When leaving Insert mode. Also when using | |
809 CTRL-O |i_CTRL-O|. But not for |i_CTRL-C|. | |
810 *MenuPopup* | |
811 MenuPopup Just before showing the popup menu (under the | |
812 right mouse button). Useful for adjusting the | |
813 menu for what is under the cursor or mouse | |
814 pointer. | |
815 The pattern is matched against a single | |
816 character representing the mode: | |
817 n Normal | |
818 v Visual | |
819 o Operator-pending | |
820 i Insert | |
843 | 821 c Command line |
6935 | 822 *OptionSet* |
823 OptionSet After setting an option. The pattern is | |
824 matched against the long option name. | |
825 The |v:option_old| variable indicates the | |
826 old option value, |v:option_new| variable | |
827 indicates the newly set value, the | |
828 |v:option_type| variable indicates whether | |

918 Only used when the "-" argument was used when | |
919 Vim was started |--|. | |
920 *SwapExists* | |
921 SwapExists Detected an existing swap file when starting | |
922 to edit a file. Only when it is possible to | |
923 select a way to handle the situation, when Vim | |
924 would ask the user what to do. | |
925 The |v:swapname| variable holds the name of | |
590 | 926 the swap file found, <afile> the file being |
927 edited. |v:swapcommand| may contain a command | |
928 to be executed in the opened file. | |
929 The commands should set the |v:swapchoice| | |
930 variable to a string with one character to | |
931 tell Vim what should be done next: | |
579 | 932 'o' open read-only |
933 'e' edit the file anyway | |
934 'r' recover | |
935 'd' delete the swap file | |
936 'q' quit, don't edit the file | |
937 'a' abort, like hitting CTRL-C | |
938 When set to an empty string the user will be | |
939 asked, as if there was no SwapExists autocmd. | |
1919 | 940 *E812* |
941 It is not allowed to change to another buffer, | |
942 change a buffer name or change directory | |
943 here. | |
13437 | 944 {only available with the +eval feature} |
579 | 945 *Syntax* |
1154 | 946 Syntax When the 'syntax' option has been set. The |
947 pattern is matched against the syntax name. | |
579 | 948 <afile> can be used for the name of the file |
949 where this option was set, and <amatch> for | |
950 the new value of 'syntax'. | |
951 See |:syn-on|. | |

579 | 966 *TermChanged* |
967 TermChanged After the value of 'term' has changed. Useful | |
968 for re-loading the syntax file to update the | |
969 colors, fonts and other terminal-dependent | |
970 settings. Executed for all loaded buffers. | |
971 *TermResponse* | |
972 TermResponse After the response to |t_RV| is received from | |
973 the terminal. The value of |v:termresponse| | |
974 can be used to do things depending on the | |
2788 | 975 terminal version. Note that this event may be |
976 triggered halfway executing another event, | |
977 especially if file I/O, a shell command or | |
978 anything else that takes time is involved. | |
4264 | 979 *TextChanged* |
980 TextChanged After a change was made to the text in the | |
981 current buffer in Normal mode. That is when | |
982 |b:changedtick| has changed. | |
983 Not triggered when there is typeahead or when | |
984 an operator is pending. | |
985 Careful: This is triggered very often, don't | |
986 do anything that the user does not expect or | |
987 that is slow. | |
988 *TextChangedI* | |
989 TextChangedI After a change was made to the text in the | |
990 current buffer in Insert mode. | |
991 Not triggered when the popup menu is visible. | |
992 Otherwise the same as TextChanged. | |

7 | 1081 ============================================================================== |
1082 6. Patterns *autocmd-patterns* *{pat}* | |
1083 | |
6741 | 1084 The {pat} argument can be a comma separated list. This works as if the |
1085 command was given with each pattern separately. Thus this command: > | |
1086 :autocmd BufRead *.txt,*.info set et | |
1087 Is equivalent to: > | |
1088 :autocmd BufRead *.txt set et | |
1089 :autocmd BufRead *.info set et | |
1090 | |
7 | 1091 The file pattern {pat} is tested for a match against the file name in one of |
1092 two ways: | |
1093 1. When there is no '/' in the pattern, Vim checks for a match against only | |
1094 the tail part of the file name (without its leading directory path). | |

|
1097 it to a full path and resolving symbolic links). |
7 | 1098 |
40 | 1099 The special pattern <buffer> or <buffer=N> is used for buffer-local |
1100 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
1101 of a buffer. | |
1102 | |
7 | 1103 Examples: > |
1104 :autocmd BufRead *.txt set et | |
1105 Set the 'et' option for all text files. > | |
1106 | |
1107 :autocmd BufRead /vim/src/*.c set cindent | |
1108 Set the 'cindent' option for C files in the /vim/src directory. > | |
1109 | |
1110 :autocmd BufRead /tmp/*.c set ts=5 | |
1111 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
1112 you start editing "/tmp/test.c", this autocommand will match. | |
1113 | |
1114 Note: To match part of a path, but not from the root directory, use a '*' as | |
1115 the first character. Example: > | |
1116 :autocmd BufRead */doc/*.txt set tw=78 | |
1117 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
1118 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
1119 | |
1120 | |
1121 The file name that the pattern is matched against is after expanding | |
1621 | 1122 wildcards. Thus if you issue this command: > |
7 | 1123 :e $ROOTDIR/main.$EXT |
1124 The argument is first expanded to: > | |
1125 /usr/root/main.py | |
1126 Before it's matched with the pattern of the autocommand. Careful with this | |
1127 when using events like FileReadCmd, the value of <amatch> may not be what you | |
1128 expect. | |
1129 | |
1130 | |
1131 Environment variables can be used in a pattern: > | |
1132 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
1133 And ~ can be used for the home directory (if $HOME is defined): > | |
1134 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
1135 :autocmd BufRead ~archive/* set readonly | |
1136 The environment variable is expanded when the autocommand is defined, not when | |
1137 the autocommand is executed. This is different from the command! | |
1138 | |
1139 *file-pattern* | |
1140 The pattern is interpreted like mostly used in file names: | |
5294 | 1141 * matches any sequence of characters; Unusual: includes path |

40 | 1165 *autocmd-changes* |
7 | 1166 Matching with the pattern is done when an event is triggered. Changing the |
1167 buffer name in one of the autocommands, or even deleting the buffer, does not | |
1168 change which autocommands will be executed. Example: > | |
1169 | |
1170 au BufEnter *.foo bdel | |
1171 au BufEnter *.foo set modified | |
1172 | |
1173 This will delete the current buffer and then set 'modified' in what has become | |
1174 the current buffer instead. Vim doesn't take into account that "*.foo" | |
1175 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
1176 buffer at the moment the event was triggered. | |
1177 | |
40 | 1178 However, buffer-local autocommands will not be executed for a buffer that has |
1179 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
1180 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
1181 still executed. | |
1182 | |
7 | 1183 ============================================================================== |
856 | 1184 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
1185 *<buffer=N>* *<buffer=abuf>* *E680* | |
40 | 1186 |
1187 Buffer-local autocommands are attached to a specific buffer. They are useful | |
1188 if the buffer does not have a name and when the name does not match a specific | |
1189 pattern. But it also means they must be explicitly added to each buffer. | |
1190 | |
1191 Instead of a pattern buffer-local autocommands use one of these forms: | |
1192 <buffer> current buffer | |
1193 <buffer=99> buffer number 99 | |
1194 <buffer=abuf> using <abuf> (only when executing autocommands) | |
1195 |<abuf>| | |
1196 | |
1197 Examples: > | |
1198 :au CursorHold <buffer> echo 'hold' | |
1199 :au CursorHold <buffer=33> echo 'hold' | |

|
1200 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
40 | 1201 |
1202 All the commands for autocommands also work with buffer-local autocommands, | |
1203 simply use the special string instead of the pattern. Examples: > | |
856 | 1204 :au! * <buffer> " remove buffer-local autocommands for |
1205 " current buffer | |
1206 :au! * <buffer=33> " remove buffer-local autocommands for | |
1207 " buffer #33 | |
1621 | 1208 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
856 | 1209 " buffers |
1210 :au * <buffer> " list buffer-local autocommands for | |
1211 " current buffer | |
40 | 1212 |
1213 Note that when an autocommand is defined for the current buffer, it is stored | |
1214 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
1215 number of the current buffer. You will see this when listing autocommands, | |
1216 for example. | |
1217 | |
1218 To test for presence of buffer-local autocommands use the |exists()| function | |
1219 as follows: > | |
1220 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
1221 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
1222 | |
1223 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
1224 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
1225 unlisted, the autocommands are still present. In order to see the removal of | |
1226 buffer-local autocommands: > | |
1227 :set verbose=6 | |
1228 | |
1229 It is not possible to define buffer-local autocommands for a non-existent | |
1230 buffer. | |
1231 | |
1232 ============================================================================== | |
1233 8. Groups *autocmd-groups* | |
7 | 1234 |
1235 Autocommands can be put together in a group. This is useful for removing or | |
1236 executing a group of autocommands. For example, all the autocommands for | |
1237 syntax highlighting are put in the "highlight" group, to be able to execute | |
1238 ":doautoall highlight BufRead" when the GUI starts. | |
1239 | |
1240 When no specific group is selected, Vim uses the default group. The default | |
1241 group does not have a name. You cannot execute the autocommands from the | |
1242 default group separately; you can execute them only by executing autocommands | |
1243 for all groups. | |
1244 | |
1245 Normally, when executing autocommands automatically, Vim uses the autocommands | |
1246 for all groups. The group only matters when executing autocommands with | |
1247 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
1248 | |
1249 The group name can contain any characters except white space. The group name | |
1250 "end" is reserved (also in uppercase). | |
1251 | |
1252 The group name is case sensitive. Note that this is different from the event | |
1253 name! | |
1254 | |
1255 *:aug* *:augroup* | |
1256 :aug[roup] {name} Define the autocmd group name for the | |
1257 following ":autocmd" commands. The name "end" | |
1258 or "END" selects the default group. | |

1268 you will get error E936. |
7 | 1269 |
1270 To enter autocommands for a specific group, use this method: | |
1271 1. Select the group with ":augroup {name}". | |
1272 2. Delete any old autocommands with ":au!". | |
1273 3. Define the autocommands. | |
1274 4. Go back to the default group with "augroup END". | |
1275 | |
1276 Example: > | |
1277 :augroup uncompress | |
1278 : au! | |
1279 : au BufEnter *.gz %!gunzip | |
1280 :augroup END | |
1281 | |
1282 This prevents having the autocommands defined twice (e.g., after sourcing the | |
1283 .vimrc file again). | |
1284 | |
1285 ============================================================================== | |
40 | 1286 9. Executing autocommands *autocmd-execute* |
7 | 1287 |
1288 Vim can also execute Autocommands non-automatically. This is useful if you | |
1289 have changed autocommands, or when Vim has executed the wrong autocommands | |
1290 (e.g., the file pattern match was wrong). | |
1291 | |
1292 Note that the 'eventignore' option applies here too. Events listed in this | |
1293 option will not cause any commands to be executed. | |
1294 | |
1295 *:do* *:doau* *:doautocmd* *E217* | |
3356 | 1296 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
7 | 1297 Apply the autocommands matching [fname] (default: |
1298 current file name) for {event} to the current buffer. | |
1299 You can use this when the current file name does not | |
1300 match the right pattern, after changing settings, or | |
1301 to execute autocommands for a certain event. | |
1302 It's possible to use this inside an autocommand too, | |
1303 so you can base the autocommands for one extension on | |
1304 another extension. Example: > | |
3224 | 1305 :au BufEnter *.cpp so ~/.vimrc_cpp |
1306 :au BufEnter *.cpp doau BufEnter x.c | |
7 | 1307 < Be careful to avoid endless loops. See |
1308 |autocmd-nested|. | |
1309 | |
1310 When the [group] argument is not given, Vim executes | |
1311 the autocommands for all groups. When the [group] | |
1312 argument is included, Vim executes only the matching | |
1313 autocommands for that group. Note: if you use an | |
1314 undefined group name, Vim gives you an error message. | |
3350 | 1315 *<nomodeline>* |
1316 After applying the autocommands the modelines are | |
1317 processed, so that their settings overrule the | |
1318 settings from autocommands, like what happens when | |
1319 editing a file. This is skipped when the <nomodeline> | |
1320 argument is present. You probably want to use | |
1321 <nomodeline> for events that are not used when loading | |
1322 a buffer, such as |User|. | |

1329 loaded buffer. Note that [fname] is used to select |
7 | 1330 the autocommands, not the buffers to which they are |
1331 applied. | |
1332 Careful: Don't use this for autocommands that delete a | |
1333 buffer, change to another buffer or change the | |
1334 contents of a buffer; the result is unpredictable. | |
1335 This command is intended for autocommands that set | |
1336 options, change highlighting, and things like that. | |
1337 | |
1338 ============================================================================== | |
40 | 1339 10. Using autocommands *autocmd-use* |
7 | 1340 |
1341 For WRITING FILES there are four possible sets of events. Vim uses only one | |
1342 of these sets for a write command: | |
1343 | |
1344 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
1345 FilterWritePre FilterWritePost writing to filter temp file | |
1346 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
1347 FileWriteCmd FileWritePre FileWritePost any other file write | |
1348 | |
1349 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
1350 writing. No further writing is done and the other events are not triggered. | |
1351 |Cmd-event| | |
1352 | |
1353 Note that the *WritePost commands should undo any changes to the buffer that | |
1354 were caused by the *WritePre commands; otherwise, writing the file will have | |
1355 the side effect of changing the buffer. | |
1356 | |
1357 Before executing the autocommands, the buffer from which the lines are to be | |
1358 written temporarily becomes the current buffer. Unless the autocommands | |
1359 change the current buffer or delete the previously current buffer, the | |
1360 previously current buffer is made the current buffer again. | |
1361 | |
1362 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
1363 which the lines are to be written. | |
1364 | |
1365 The '[ and '] marks have a special position: | |
1366 - Before the *ReadPre event the '[ mark is set to the line just above where | |
1367 the new lines will be inserted. | |
1368 - Before the *ReadPost event the '[ mark is set to the first line that was | |
1369 just read, the '] mark to the last line. | |
26 | 1370 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
1371 mark is set to the first line that will be written, the '] mark to the last | |
1372 line. | |
7 | 1373 Careful: '[ and '] change when using commands that change the buffer. |
1374 | |
1375 In commands which expect a file name, you can use "<afile>" for the file name | |
1376 that is being read |:<afile>| (you can also use "%" for the current file | |
1377 name). "<abuf>" can be used for the buffer number of the currently effective | |
1378 buffer. This also works for buffers that doesn't have a name. But it doesn't | |
1379 work for files without a buffer (e.g., with ":r file"). | |
1380 | |
1381 *gzip-example* | |
1382 Examples for reading and writing compressed files: > | |
1383 :augroup gzip | |
1384 : autocmd! | |
1385 : autocmd BufReadPre,FileReadPre *.gz set bin | |
1386 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
1387 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
1388 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
1389 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
1390 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
1391 | |
1392 : autocmd FileAppendPre *.gz !gunzip <afile> | |
1393 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
1394 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
1395 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
1396 :augroup END | |
1397 | |
1398 The "gzip" group is used to be able to delete any existing autocommands with | |
1399 ":autocmd!", for when the file is sourced twice. | |
1400 | |
1401 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
1402 | |
1403 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
1404 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
1405 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
1406 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
1407 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
1408 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
1409 'modified' option. | |
1410 | |
1411 To execute Normal mode commands from an autocommand, use the ":normal" | |
1412 command. Use with care! If the Normal mode command is not finished, the user | |
1413 needs to type characters (e.g., after ":normal m" you need to type a mark | |
1414 name). | |
1415 | |
1416 If you want the buffer to be unmodified after changing it, reset the | |
1417 'modified' option. This makes it possible to exit the buffer with ":q" | |
1418 instead of ":q!". | |
1419 | |
1420 *autocmd-nested* *E218* | |
1421 By default, autocommands do not nest. If you use ":e" or ":w" in an | |
1422 autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
1423 those commands. If you do want this, use the "nested" flag for those commands | |
1424 in which you want nesting. For example: > | |
1425 :autocmd FileChangedShell *.c nested e! | |
1426 The nesting is limited to 10 levels to get out of recursive loops. | |
1427 | |
1428 It's possible to use the ":au" command in an autocommand. This can be a | |
1429 self-modifying command! This can be useful for an autocommand that should | |
1430 execute only once. | |
1431 | |
590 | 1432 If you want to skip autocommands for one command, use the |:noautocmd| command |
1433 modifier or the 'eventignore' option. | |
7 | 1434 |
1435 Note: When reading a file (with ":read file" or with a filter command) and the | |
1436 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
1437 write (with ":write file" or with a filter command), if the same line is | |
1438 written again as the last line in a file AND 'binary' is set, Vim does not | |
1439 supply an <EOL>. This makes a filter command on the just read lines write the | |
1440 same file as was read, and makes a write command on just filtered lines write | |
1441 the same file as was read from the filter. For example, another way to write | |
1442 a compressed file: > | |
1443 | |
1444 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
1445 :autocmd FileWritePost *.gz undo|set nobin | |
1446 < | |
1447 *autocommand-pattern* | |
1448 You can specify multiple patterns, separated by commas. Here are some | |
1449 examples: > | |
1450 | |
1451 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
1452 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
1453 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
1454 :autocmd BufLeave .letter set dict= | |
1455 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
1456 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
1457 :autocmd BufLeave *.c,*.h unabbr FOR | |
1458 | |
1459 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
1460 | |
1461 :autocmd BufEnter ?akefile* set include=^s\=include | |
1462 :autocmd BufLeave ?akefile* set include& | |
1463 | |
1464 To always start editing C files at the first function: > | |
1465 | |
1466 :autocmd BufRead *.c,*.h 1;/^{ | |
1467 | |
1468 Without the "1;" above, the search would start from wherever the file was | |
1469 entered, rather than from the start of the file. | |
1470 | |
1471 *skeleton* *template* | |
1472 To read a skeleton (template) file when opening a new file: > | |
1473 | |
1474 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
1475 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
1476 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
1477 | |
1478 To insert the current date and time in a *.html file when writing it: > | |
1479 | |
1480 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
1481 :fun LastMod() | |
1482 : if line("$") > 20 | |
1483 : let l = 20 | |
1484 : else | |
1485 : let l = line("$") | |
1486 : endif | |
1487 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
1488 : \ strftime("%Y %b %d") | |
1489 :endfun | |
1490 | |
1491 You need to have a line "Last modified: <date time>" in the first 20 lines | |
1492 of the file for this to work. Vim replaces <date time> (and anything in the | |
1493 same line after it) with the current date and time. Explanation: | |
1494 ks mark current position with mark 's' | |
1495 call LastMod() call the LastMod() function to do the work | |
1496 's return the cursor to the old position | |
1497 The LastMod() function checks if the file is shorter than 20 lines, and then | |
1498 uses the ":g" command to find lines that contain "Last modified: ". For those | |
1499 lines the ":s" command is executed to replace the existing date with the | |
1500 current one. The ":execute" command is used to be able to use an expression | |
1501 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
1502 function. You can change its argument to get another date string. | |
1503 | |
1504 When entering :autocmd on the command-line, completion of events and command | |
1505 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
1506 | |
1507 Vim executes all matching autocommands in the order that you specify them. | |
1508 It is recommended that your first autocommand be used for all files by using | |
1509 "*" as the file pattern. This means that you can define defaults you like | |
1510 here for any settings, and if there is another matching autocommand it will | |
1511 override these. But if there is no other matching autocommand, then at least | |
1512 your default settings are recovered (if entering this file from another for | |
1513 which autocommands did match). Note that "*" will also match files starting | |
1514 with ".", unlike Unix shells. | |
1515 | |
1516 *autocmd-searchpat* | |
1517 Autocommands do not change the current search patterns. Vim saves the current | |
1518 search patterns before executing autocommands then restores them after the | |
1519 autocommands finish. This means that autocommands do not affect the strings | |
1520 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
1521 use search patterns normally, e.g., with the "n" command. | |
1522 If you want an autocommand to set the search pattern, such that it is used | |
1523 after the autocommand finishes, use the ":let @/ =" command. | |
1524 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
1525 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
1526 highlighting when starting Vim. | |
1527 | |
1528 *Cmd-event* | |
1529 When using one of the "*Cmd" events, the matching autocommands are expected to | |
1061 | 1530 do the file reading, writing or sourcing. This can be used when working with |
1531 a special kind of file, for example on a remote system. | |
7 | 1532 CAREFUL: If you use these events in a wrong way, it may have the effect of |
1533 making it impossible to read or write the matching files! Make sure you test | |
1534 your autocommands properly. Best is to use a pattern that will never match a | |
1535 normal file name, for example "ftp://*". | |
1536 | |
1537 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
1538 editing session. When recovering from the original file, Vim reads only those | |
1539 parts of a file that are not found in the swap file. Since that is not | |
1540 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
1541 original file isn't needed for recovery. You might want to do this only when | |
1542 you expect the file to be modified. | |
1543 | |
1061 | 1544 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
1545 and "++ff=" argument that are effective. These should be used for the command | |
1546 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
1547 used, zero otherwise. | |

1552 11. Disabling autocommands *autocmd-disable* | |
1553 | |
1554 To disable autocommands for some time use the 'eventignore' option. Note that | |
1555 this may cause unexpected behavior, make sure you restore 'eventignore' | |
1556 afterwards, using a |:try| block with |:finally|. | |
1557 | |
1558 *:noautocmd* *:noa* | |
1559 To disable autocommands for just one command use the ":noautocmd" command | |
1560 modifier. This will set 'eventignore' to "all" for the duration of the | |
1561 following command. Example: > | |
1562 | |
1563 :noautocmd w fname.gz | |
1564 | |
1565 This will write the file without triggering the autocommands defined by the | |
1566 gzip plugin. | |
