possible.

| 24 ============================================================================== | |
| 25 1. Introduction *autocmd-intro* | |
| 26 | |
| 22 | 27 You can specify commands to be executed automatically when reading or writing |
| 28 a file, when entering or leaving a buffer or window, and when exiting Vim. | |
| 29 For example, you can create an autocommand to set the 'cindent' option for | |
| 30 files matching *.c. You can also use autocommands to implement advanced | |
| 7 | 31 features, such as editing compressed files (see |gzip-example|). The usual |
| 32 place to put autocommands is in your .vimrc or .exrc file. | |
| 33 | |
| 13231 | 34 *E203* *E204* *E143* *E855* *E937* *E952* |
| 7 | 35 WARNING: Using autocommands is very powerful, and may lead to unexpected side |
| 36 effects. Be careful not to destroy your text. | |
| 37 - It's a good idea to do some testing on an expendable copy of a file first. | |
| 38 For example: If you use autocommands to decompress a file when starting to | |
| 39 edit it, make sure that the autocommands for compressing when writing work | |
| 40 correctly. | |
| 41 - Be prepared for an error halfway through (e.g., disk full). Vim will mostly | |
| 42 be able to undo the changes to the buffer, but you may have to clean up the | |
| 43 changes to other files by hand (e.g., compress a file that has been | |
| 44 decompressed). | |
| 45 - If the BufRead* events allow you to edit a compressed file, the FileRead* | |
| 46 events should do the same (this makes recovery possible in some rare cases). | |
| 47 It's a good idea to use the same autocommands for the File* and Buf* events | |
| 48 when possible. | |

| 7 | 86 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
| 87 arguments are not expanded when the autocommand is defined. These will be | |
| 88 expanded when the Event is recognized, and the {cmd} is executed. The only | |
| 89 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
| 90 > | |
| 91 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
| 92 | |
| 93 Here Vim expands <sfile> to the name of the file containing this line. | |

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

160 group, it breaks plugins, syntax highlighting, etc. |
| 7 | 161 |
| 162 When the [group] argument is not given, Vim uses the current group (as defined | |
| 163 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
| 164 | |
| 165 ============================================================================== | |
| 166 4. Listing autocommands *autocmd-list* | |
| 167 | |
| 168 :au[tocmd] [group] {event} {pat} | |
| 169 Show the autocommands associated with {event} and | |
| 170 {pat}. | |
| 171 | |
| 172 :au[tocmd] [group] * {pat} | |
| 173 Show the autocommands associated with {pat} for all | |
| 174 events. | |
| 175 | |
| 176 :au[tocmd] [group] {event} | |
| 177 Show all autocommands for {event}. | |
| 178 | |
| 179 :au[tocmd] [group] Show all autocommands. | |
| 180 | |
| 181 If you provide the [group] argument, Vim lists only the autocommands for | |
| 182 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 183 argument behavior differs from that for defining and removing autocommands. | |
| 184 | |
| 40 | 185 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 186 or <buffer=N>. See |autocmd-buflocal|. | |
| 187 | |
| 500 | 188 *:autocmd-verbose* |
| 189 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 190 was last defined. Example: > | |
| 191 | |
| 192 :verbose autocmd BufEnter | |
| 193 FileExplorer BufEnter | |
| 856 | 194 * call s:LocalBrowse(expand("<amatch>")) |
| 500 | 195 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
| 196 < | |
| 197 See |:verbose-cmd| for more information. | |
| 198 | |
| 7 | 199 ============================================================================== |
| 200 5. Events *autocmd-events* *E215* *E216* | |
| 201 | |
| 579 | 202 You can specify a comma-separated list of event names. No white space can be |
| 203 used in this list. The command applies to all the events in the list. | |
| 204 | |
| 205 For READING FILES there are four kinds of events possible: | |
| 206 BufNewFile starting to edit a non-existent file | |
| 207 BufReadPre BufReadPost starting to edit an existing file | |
| 208 FilterReadPre FilterReadPost read the temp file with filter output | |
| 209 FileReadPre FileReadPost any other file read | |
| 210 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 211 "Post" events are both triggered, before and after reading the file. | |
| 212 | |
| 213 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 214 are not allowed to change the current buffer (you will get an error message if | |
| 215 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 216 | |
| 217 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 218 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 219 autocommands, this doesn't happen. | |
| 220 | |
| 221 You can use the 'eventignore' option to ignore a number of events or all | |
| 222 events. | |
| 7 | 223 *autocommand-events* *{event}* |
| 224 Vim recognizes the following events. Vim ignores the case of event names | |
| 225 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 226 | |
| 579 | 227 First an overview by function with a short explanation. Then the list |
| 843 | 228 alphabetically with full explanations |autocmd-events-abc|. |

| 232 Reading | |

395 during startup. |
| 579 | 396 The BufCreate event is for historic reasons. |
| 397 NOTE: When this autocommand is executed, the | |
| 398 current buffer "%" may be different from the | |
| 399 buffer being created "<afile>". | |
| 400 *BufDelete* | |
| 401 BufDelete Before deleting a buffer from the buffer list. | |
| 402 The BufUnload may be called first (if the | |
| 403 buffer was loaded). | |
| 404 Also used just before a buffer in the buffer | |
| 405 list is renamed. | |
| 406 NOTE: When this autocommand is executed, the | |
| 407 current buffer "%" may be different from the | |
| 1621 | 408 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 409 Don't change to another buffer, it will cause |
| 410 problems. | |
| 579 | 411 *BufEnter* |
| 412 BufEnter After entering a buffer. Useful for setting | |
| 413 options for a file type. Also executed when | |
| 414 starting to edit a buffer, after the | |
| 415 BufReadPost autocommands. | |
| 416 *BufFilePost* | |
| 417 BufFilePost After changing the name of the current buffer | |
| 418 with the ":file" or ":saveas" command. | |
| 625 | 419 *BufFilePre* |
| 579 | 420 BufFilePre Before changing the name of the current buffer |
| 421 with the ":file" or ":saveas" command. | |
| 422 *BufHidden* | |
| 17261 | 423 BufHidden Just before a buffer becomes hidden. That is, |
| 424 when there are no longer windows that show | |
| 579 | 425 the buffer, but the buffer is not unloaded or |
| 426 deleted. Not used for ":qa" or ":q" when | |
| 427 exiting Vim. | |
| 428 NOTE: When this autocommand is executed, the | |
| 429 current buffer "%" may be different from the | |
| 430 buffer being unloaded "<afile>". | |
| 431 *BufLeave* | |
| 432 BufLeave Before leaving to another buffer. Also when | |
| 433 leaving or closing the current window and the | |
| 434 new current window is not for the same buffer. | |
| 435 Not used for ":qa" or ":q" when exiting Vim. | |
| 436 *BufNew* | |
| 437 BufNew Just after creating a new buffer. Also used | |
| 438 just after a buffer has been renamed. When | |
| 439 the buffer is added to the buffer list BufAdd | |
| 440 will be triggered too. | |
| 441 NOTE: When this autocommand is executed, the | |
| 442 current buffer "%" may be different from the | |
| 443 buffer being created "<afile>". | |
| 7 | 444 *BufNewFile* |
| 445 BufNewFile When starting to edit a file that doesn't | |
| 446 exist. Can be used to read in a skeleton | |
| 447 file. | |
| 448 *BufRead* *BufReadPost* | |
| 449 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 450 reading the file into the buffer, before | |
| 451 executing the modelines. See |BufWinEnter| | |
| 452 for when you need to do something after | |
| 453 processing the modelines. | |
| 454 This does NOT work for ":r file". Not used | |
| 455 when the file doesn't exist. Also used after | |
| 456 successfully recovering a file. | |
| 3682 | 457 Also triggered for the filetypedetect group |
| 458 when executing ":filetype detect" and when | |
| 459 writing an unnamed buffer in a way that the | |
| 460 buffer gets a name. | |
| 625 | 461 *BufReadCmd* |
| 7 | 462 BufReadCmd Before starting to edit a new buffer. Should |
| 463 read the file into the buffer. |Cmd-event| | |
| 625 | 464 *BufReadPre* *E200* *E201* |
| 579 | 465 BufReadPre When starting to edit a new buffer, before |
| 466 reading the file into the buffer. Not used | |
| 467 if the file doesn't exist. | |
| 468 *BufUnload* | |
| 469 BufUnload Before unloading a buffer. This is when the | |
| 470 text in the buffer is going to be freed. This | |
| 471 may be after a BufWritePost and before a | |
| 472 BufDelete. Also used for all buffers that are | |
| 473 loaded when Vim is going to exit. | |
| 474 NOTE: When this autocommand is executed, the | |
| 475 current buffer "%" may be different from the | |
| 476 buffer being unloaded "<afile>". | |

480 event is not triggered. |
| 579 | 481 *BufWinEnter* |
| 482 BufWinEnter After a buffer is displayed in a window. This | |
| 483 can be when the buffer is loaded (after | |
| 1621 | 484 processing the modelines) or when a hidden |
| 579 | 485 buffer is displayed in a window (and is no |
| 1621 | 486 longer hidden). |
| 487 Does not happen for |:split| without | |
| 488 arguments, since you keep editing the same | |
| 489 buffer, or ":split" with a file that's already | |
| 1668 | 490 open in a window, because it re-uses an |
| 491 existing buffer. But it does happen for a | |
| 492 ":split" with the name of the current buffer, | |
| 493 since it reloads that buffer. | |

| 521 *BufWriteCmd* | |
| 522 BufWriteCmd Before writing the whole buffer to a file. | |
| 523 Should do the writing of the file and reset | |
| 39 | 524 'modified' if successful, unless '+' is in |
| 525 'cpo' and writing to another file |cpo-+|. | |
| 526 The buffer contents should not be changed. | |
| 3082 | 527 When the command resets 'modified' the undo |
| 528 information is adjusted to mark older undo | |
| 529 states as 'modified', like |:write| does. | |
| 39 | 530 |Cmd-event| |
| 579 | 531 *BufWritePost* |
| 532 BufWritePost After writing the whole buffer to a file | |
| 533 (should undo the commands for BufWritePre). | |
| 6154 | 534 *CmdUndefined* |
| 535 CmdUndefined When a user command is used but it isn't | |
| 536 defined. Useful for defining a command only | |
| 537 when it's used. The pattern is matched | |
| 538 against the command name. Both <amatch> and | |
| 539 <afile> are set to the name of the command. | |
| 540 NOTE: Autocompletion won't work until the | |
| 541 command is defined. An alternative is to | |
| 542 always define the user command and have it | |
| 543 invoke an autoloaded function. See |autoload|. | |

| 579 | 632 *CursorHold* |
| 633 CursorHold When the user doesn't press a key for the time | |

| 635 until the user has pressed a key (i.e. doesn't | |
| 636 fire every 'updatetime' ms if you leave Vim to | |
| 637 make some coffee. :) See |CursorHold-example| | |
| 638 for previewing tags. | |
| 639 This event is only triggered in Normal mode. | |
| 1154 | 640 It is not triggered when waiting for a command |
| 641 argument to be typed, or a movement after an | |
| 642 operator. | |
| 610 | 643 While recording the CursorHold event is not |
| 644 triggered. |q| | |
| 6259 | 645 *<CursorHold>* |
| 646 Internally the autocommand is triggered by the | |
| 647 <CursorHold> key. In an expression mapping | |
| 648 |getchar()| may see this character. | |
| 649 | |
| 579 | 650 Note: Interactive commands cannot be used for |
| 651 this event. There is no hit-enter prompt, | |
| 652 the screen is updated directly (when needed). | |
| 653 Note: In the future there will probably be | |
| 654 another option to set the time. | |
| 655 Hint: to force an update of the status lines | |
| 656 use: > | |

| 18972 | 658 < {only on Amiga, Unix, Win32 and all GUI |

| 699 This event is triggered when making the first | |
| 700 change in a buffer or the first change after | |
| 823 | 701 'readonly' was set, just before the change is |
| 702 applied to the text. | |
| 579 | 703 WARNING: If the autocommand moves the cursor |

| 733 cancelled if there is a modified buffer that | |
| 734 isn't automatically saved, use |VimLeavePre| | |
| 735 for really exiting. | |
| 7 | 736 *FileChangedShell* |
| 737 FileChangedShell When Vim notices that the modification time of | |
| 738 a file has changed since editing started. | |
| 739 Also when the file attributes of the file | |
| 5908 | 740 change or when the size of the file changes. |
| 741 |timestamp| | |
| 7 | 742 Mostly triggered after executing a shell |
| 743 command, but also with a |:checktime| command | |
| 11473 | 744 or when gvim regains input focus. |
| 7 | 745 This autocommand is triggered for each changed |
| 746 file. It is not used when 'autoread' is set | |
| 747 and the buffer was not changed. If a | |
| 748 FileChangedShell autocommand is present the | |
| 749 warning message and prompt is not given. | |
| 179 | 750 The |v:fcs_reason| variable is set to indicate |
| 751 what happened and |v:fcs_choice| can be used | |
| 752 to tell Vim what to do next. | |
| 7 | 753 NOTE: When this autocommand is executed, the |
| 754 current buffer "%" may be different from the | |
| 11347 | 755 buffer that was changed, which is in "<afile>". |
| 7 | 756 NOTE: The commands must not change the current |

758 buffer. *E246* *E811* |
| 7 | 759 NOTE: This event never nests, to avoid an |
| 760 endless loop. This means that while executing | |
| 761 commands for the FileChangedShell event no | |
| 762 other FileChangedShell event will be | |
| 763 triggered. | |
| 766 | 764 *FileChangedShellPost* |
| 765 FileChangedShellPost After handling a file that was changed outside | |
| 766 of Vim. Can be used to update the statusline. | |
| 579 | 767 *FileEncoding* |
| 768 FileEncoding Obsolete. It still works and is equivalent | |
| 769 to |EncodingChanged|. | |
| 770 *FileReadCmd* | |
| 771 FileReadCmd Before reading a file with a ":read" command. | |
| 772 Should do the reading of the file. |Cmd-event| | |
| 773 *FileReadPost* | |
| 774 FileReadPost After reading a file with a ":read" command. | |
| 775 Note that Vim sets the '[ and '] marks to the | |
| 776 first and last line of the read. This can be | |
| 777 used to operate on the lines just read. | |
| 778 *FileReadPre* | |
| 779 FileReadPre Before reading a file with a ":read" command. | |
| 780 *FileType* | |
| 1154 | 781 FileType When the 'filetype' option has been set. The |
| 782 pattern is matched against the filetype. | |

| 788 *FileWriteCmd* | |
| 789 FileWriteCmd Before writing to a file, when not writing the | |
| 790 whole buffer. Should do the writing to the | |
| 791 file. Should not change the buffer. Use the | |
| 792 '[ and '] marks for the range of lines. | |
| 793 |Cmd-event| | |
| 794 *FileWritePost* | |
| 795 FileWritePost After writing to a file, when not writing the | |
| 796 whole buffer. | |
| 797 *FileWritePre* | |
| 798 FileWritePre Before writing to a file, when not writing the | |
| 799 whole buffer. Use the '[ and '] marks for the | |
| 800 range of lines. | |
| 801 *FilterReadPost* | |
| 802 FilterReadPost After reading a file from a filter command. | |
| 803 Vim checks the pattern against the name of | |
| 804 the current buffer as with FilterReadPre. | |
| 805 Not triggered when 'shelltemp' is off. | |
| 806 *FilterReadPre* *E135* | |
| 807 FilterReadPre Before reading a file from a filter command. | |
| 808 Vim checks the pattern against the name of | |
| 809 the current buffer, not the name of the | |
| 810 temporary file that is the output of the | |
| 811 filter command. | |
| 812 Not triggered when 'shelltemp' is off. | |
| 813 *FilterWritePost* | |
| 814 FilterWritePost After writing a file for a filter command or | |
| 15334 | 815 making a diff with an external diff (see |
| 816 DiffUpdated for internal diff). | |
| 579 | 817 Vim checks the pattern against the name of |
| 818 the current buffer as with FilterWritePre. | |
| 819 Not triggered when 'shelltemp' is off. | |
| 820 *FilterWritePre* | |
| 821 FilterWritePre Before writing a file for a filter command or | |
| 15334 | 822 making a diff with an external diff. |
| 579 | 823 Vim checks the pattern against the name of |
| 824 the current buffer, not the name of the | |
| 825 temporary file that is the output of the | |
| 826 filter command. | |
| 827 Not triggered when 'shelltemp' is off. | |
| 7 | 828 *FocusGained* |
| 829 FocusGained When Vim got input focus. Only for the GUI | |
| 830 version and a few console versions where this | |
| 831 can be detected. | |
| 832 *FocusLost* | |
| 833 FocusLost When Vim lost input focus. Only for the GUI | |
| 834 version and a few console versions where this | |
| 11 | 835 can be detected. May also happen when a |
| 836 dialog pops up. | |
| 7 | 837 *FuncUndefined* |
| 838 FuncUndefined When a user function is used but it isn't | |
| 839 defined. Useful for defining a function only | |
| 1154 | 840 when it's used. The pattern is matched |
| 841 against the function name. Both <amatch> and | |
| 842 <afile> are set to the name of the function. | |
| 6154 | 843 NOTE: When writing Vim scripts a better |
| 844 alternative is to use an autoloaded function. | |
| 161 | 845 See |autoload-functions|. |
| 579 | 846 *GUIEnter* |
| 847 GUIEnter After starting the GUI successfully, and after | |
| 848 opening the window. It is triggered before | |
| 849 VimEnter when using gvim. Can be used to | |
| 850 position the window from a .gvimrc file: > | |
| 851 :autocmd GUIEnter * winpos 100 50 | |
| 1154 | 852 < *GUIFailed* |
| 853 GUIFailed After starting the GUI failed. Vim may | |
| 854 continue to run in the terminal, if possible | |
| 855 (only on Unix and alikes, when connecting the | |
| 856 X server fails). You may want to quit Vim: > | |
| 857 :autocmd GUIFailed * qall | |
| 579 | 858 < *InsertChange* |
| 859 InsertChange When typing <Insert> while in Insert or | |
| 860 Replace mode. The |v:insertmode| variable | |
| 861 indicates the new mode. | |
| 862 Be careful not to move the cursor or do | |
| 863 anything else that the user does not expect. | |
| 2845 | 864 *InsertCharPre* |
| 865 InsertCharPre When a character is typed in Insert mode, | |
| 866 before inserting the char. | |
| 867 The |v:char| variable indicates the char typed | |
| 868 and can be changed during the event to insert | |
| 869 a different character. When |v:char| is set | |
| 870 to more than one character this text is | |
| 871 inserted literally. | |
| 872 It is not allowed to change the text |textlock|. | |
| 873 The event is not triggered when 'paste' is | |
| 13437 | 874 set. {only with the +eval feature} |
| 579 | 875 *InsertEnter* |
| 1154 | 876 InsertEnter Just before starting Insert mode. Also for |
| 877 Replace mode and Virtual Replace mode. The | |
| 579 | 878 |v:insertmode| variable indicates the mode. |
| 4448 | 879 Be careful not to do anything else that the |
| 880 user does not expect. | |
| 881 The cursor is restored afterwards. If you do | |
| 882 not want that set |v:char| to a non-empty | |
| 883 string. | |
| 579 | 884 *InsertLeave* |
| 885 InsertLeave When leaving Insert mode. Also when using | |
| 886 CTRL-O |i_CTRL-O|. But not for |i_CTRL-C|. | |
| 887 *MenuPopup* | |
| 888 MenuPopup Just before showing the popup menu (under the | |
| 889 right mouse button). Useful for adjusting the | |
| 890 menu for what is under the cursor or mouse | |
| 891 pointer. | |

| 1047 Only used when the "-" argument was used when | |
| 1048 Vim was started |--|. | |
| 1049 *SwapExists* | |
| 1050 SwapExists Detected an existing swap file when starting | |
| 1051 to edit a file. Only when it is possible to | |
| 1052 select a way to handle the situation, when Vim | |
| 1053 would ask the user what to do. | |
| 1054 The |v:swapname| variable holds the name of | |
| 590 | 1055 the swap file found, <afile> the file being |
| 1056 edited. |v:swapcommand| may contain a command | |
| 1057 to be executed in the opened file. | |
| 1058 The commands should set the |v:swapchoice| | |
| 1059 variable to a string with one character to | |
| 1060 tell Vim what should be done next: | |
| 579 | 1061 'o' open read-only |
| 1062 'e' edit the file anyway | |
| 1063 'r' recover | |
| 1064 'd' delete the swap file | |
| 1065 'q' quit, don't edit the file | |
| 1066 'a' abort, like hitting CTRL-C | |
| 1067 When set to an empty string the user will be | |
| 1068 asked, as if there was no SwapExists autocmd. | |

| 1122 |b:changedtick| has changed (also when that | |

| 1243 6. Patterns *autocmd-patterns* *{pat}* | |
| 1244 | |
| 6741 | 1245 The {pat} argument can be a comma separated list. This works as if the |
| 1246 command was given with each pattern separately. Thus this command: > | |
| 1247 :autocmd BufRead *.txt,*.info set et | |
| 1248 Is equivalent to: > | |
| 1249 :autocmd BufRead *.txt set et | |
| 1250 :autocmd BufRead *.info set et | |
| 1251 | |
| 7 | 1252 The file pattern {pat} is tested for a match against the file name in one of |
| 1253 two ways: | |
| 1254 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1255 the tail part of the file name (without its leading directory path). | |

1258 it to a full path and resolving symbolic links). |
| 7 | 1259 |
| 40 | 1260 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1261 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1262 of a buffer. | |
| 1263 | |
| 7 | 1264 Examples: > |
| 1265 :autocmd BufRead *.txt set et | |
| 1266 Set the 'et' option for all text files. > | |
| 1267 | |
| 1268 :autocmd BufRead /vim/src/*.c set cindent | |
| 1269 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1270 | |
| 1271 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1272 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1273 you start editing "/tmp/test.c", this autocommand will match. | |
| 1274 | |
| 1275 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1276 the first character. Example: > | |
| 1277 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1278 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1279 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1280 | |
| 1281 | |
| 1282 The file name that the pattern is matched against is after expanding | |
| 1621 | 1283 wildcards. Thus if you issue this command: > |
| 7 | 1284 :e $ROOTDIR/main.$EXT |
| 1285 The argument is first expanded to: > | |
| 1286 /usr/root/main.py | |
| 1287 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1288 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1289 expect. | |
| 1290 | |
| 1291 | |
| 1292 Environment variables can be used in a pattern: > | |
| 1293 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1294 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1295 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1296 :autocmd BufRead ~archive/* set readonly | |
| 1297 The environment variable is expanded when the autocommand is defined, not when | |
| 1298 the autocommand is executed. This is different from the command! | |
| 1299 | |
| 1300 *file-pattern* | |
| 1301 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1302 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1303 separators |
| 7 | 1304 ? matches any single character |
| 1305 \? matches a '?' | |
| 1306 . matches a '.' | |
| 1307 ~ matches a '~' | |
| 1308 , separates patterns | |
| 1309 \, matches a ',' | |
| 1310 { } like \( \) in a |pattern| | |
| 1311 , inside { }: like \| in a |pattern| | |

| 40 | 1326 *autocmd-changes* |
| 7 | 1327 Matching with the pattern is done when an event is triggered. Changing the |
| 1328 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1329 change which autocommands will be executed. Example: > | |
| 1330 | |
| 1331 au BufEnter *.foo bdel | |
| 1332 au BufEnter *.foo set modified | |
| 1333 | |
| 1334 This will delete the current buffer and then set 'modified' in what has become | |
| 1335 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1336 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1337 buffer at the moment the event was triggered. | |
| 1338 | |
| 40 | 1339 However, buffer-local autocommands will not be executed for a buffer that has |
| 1340 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1341 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1342 still executed. | |
| 1343 | |
| 7 | 1344 ============================================================================== |
| 856 | 1345 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1346 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1347 |
| 1348 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1349 if the buffer does not have a name and when the name does not match a specific | |
| 1350 pattern. But it also means they must be explicitly added to each buffer. | |
| 1351 | |
| 1352 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1353 <buffer> current buffer | |
| 1354 <buffer=99> buffer number 99 | |
| 1355 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1356 |<abuf>| | |
| 1357 | |
| 1358 Examples: > | |
| 1359 :au CursorHold <buffer> echo 'hold' | |
| 1360 :au CursorHold <buffer=33> echo 'hold' | |

1361 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1362 |
| 1363 All the commands for autocommands also work with buffer-local autocommands, | |
| 1364 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1365 :au! * <buffer> " remove buffer-local autocommands for |
| 1366 " current buffer | |
| 1367 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1368 " buffer #33 | |
| 1621 | 1369 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1370 " buffers |
| 1371 :au * <buffer> " list buffer-local autocommands for | |
| 1372 " current buffer | |
| 40 | 1373 |
| 1374 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1375 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1376 number of the current buffer. You will see this when listing autocommands, | |
| 1377 for example. | |
| 1378 | |
| 1379 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1380 as follows: > | |
| 1381 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1382 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1383 | |
| 1384 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1385 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1386 unlisted, the autocommands are still present. In order to see the removal of | |
| 1387 buffer-local autocommands: > | |
| 1388 :set verbose=6 | |
| 1389 | |
| 1390 It is not possible to define buffer-local autocommands for a non-existent | |
| 1391 buffer. | |
| 1392 | |
| 1393 ============================================================================== | |
| 1394 8. Groups *autocmd-groups* | |
| 7 | 1395 |
| 1396 Autocommands can be put together in a group. This is useful for removing or | |
| 1397 executing a group of autocommands. For example, all the autocommands for | |
| 1398 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1399 ":doautoall highlight BufRead" when the GUI starts. | |
| 1400 | |
| 1401 When no specific group is selected, Vim uses the default group. The default | |
| 1402 group does not have a name. You cannot execute the autocommands from the | |
| 1403 default group separately; you can execute them only by executing autocommands | |
| 1404 for all groups. | |
| 1405 | |
| 1406 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1407 for all groups. The group only matters when executing autocommands with | |
| 1408 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1409 | |
| 1410 The group name can contain any characters except white space. The group name | |
| 1411 "end" is reserved (also in uppercase). | |
| 1412 | |
| 1413 The group name is case sensitive. Note that this is different from the event | |
| 1414 name! | |
| 1415 | |
| 1416 *:aug* *:augroup* | |
| 1417 :aug[roup] {name} Define the autocmd group name for the | |
| 1418 following ":autocmd" commands. The name "end" | |
| 1419 or "END" selects the default group. | |

1429 you will get error E936. |
| 7 | 1430 |
| 1431 To enter autocommands for a specific group, use this method: | |
| 1432 1. Select the group with ":augroup {name}". | |
| 1433 2. Delete any old autocommands with ":au!". | |
| 1434 3. Define the autocommands. | |
| 1435 4. Go back to the default group with "augroup END". | |
| 1436 | |
| 1437 Example: > | |
| 1438 :augroup uncompress | |
| 1439 : au! | |
| 1440 : au BufEnter *.gz %!gunzip | |
| 1441 :augroup END | |
| 1442 | |
| 1443 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1444 .vimrc file again). | |
| 1445 | |
| 1446 ============================================================================== | |
| 40 | 1447 9. Executing autocommands *autocmd-execute* |
| 7 | 1448 |
| 1449 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1450 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1451 (e.g., the file pattern match was wrong). | |
| 1452 | |
| 1453 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1454 option will not cause any commands to be executed. | |
| 1455 | |
| 16944 | 1456 *:do* *:doau* *:doaut* *:doautocmd* *E217* |
| 3356 | 1457 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1458 Apply the autocommands matching [fname] (default: |
| 1459 current file name) for {event} to the current buffer. | |
| 1460 You can use this when the current file name does not | |
| 1461 match the right pattern, after changing settings, or | |
| 1462 to execute autocommands for a certain event. | |
| 1463 It's possible to use this inside an autocommand too, | |
| 1464 so you can base the autocommands for one extension on | |
| 1465 another extension. Example: > | |
| 3224 | 1466 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1467 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1468 < Be careful to avoid endless loops. See |
| 1469 |autocmd-nested|. | |
| 1470 | |
| 1471 When the [group] argument is not given, Vim executes | |
| 1472 the autocommands for all groups. When the [group] | |
| 1473 argument is included, Vim executes only the matching | |
| 1474 autocommands for that group. Note: if you use an | |
| 1475 undefined group name, Vim gives you an error message. | |
| 3350 | 1476 *<nomodeline>* |
| 1477 After applying the autocommands the modelines are | |
| 1478 processed, so that their settings overrule the | |
| 1479 settings from autocommands, like what happens when | |
| 1480 editing a file. This is skipped when the <nomodeline> | |
| 1481 argument is present. You probably want to use | |
| 1482 <nomodeline> for events that are not used when loading | |
| 1483 a buffer, such as |User|. | |

1490 loaded buffer. Note that [fname] is used to select |
| 7 | 1491 the autocommands, not the buffers to which they are |
| 1492 applied. | |
| 1493 Careful: Don't use this for autocommands that delete a | |
| 1494 buffer, change to another buffer or change the | |
| 1495 contents of a buffer; the result is unpredictable. | |
| 1496 This command is intended for autocommands that set | |
| 1497 options, change highlighting, and things like that. | |
| 1498 | |
| 1499 ============================================================================== | |
| 40 | 1500 10. Using autocommands *autocmd-use* |
| 7 | 1501 |
| 1502 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1503 of these sets for a write command: | |
| 1504 | |
| 1505 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1506 FilterWritePre FilterWritePost writing to filter temp file | |
| 1507 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1508 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1509 | |
| 1510 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1511 writing. No further writing is done and the other events are not triggered. | |
| 1512 |Cmd-event| | |
| 1513 | |
| 1514 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1515 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1516 the side effect of changing the buffer. | |
| 1517 | |
| 1518 Before executing the autocommands, the buffer from which the lines are to be | |
| 1519 written temporarily becomes the current buffer. Unless the autocommands | |
| 1520 change the current buffer or delete the previously current buffer, the | |
| 1521 previously current buffer is made the current buffer again. | |
| 1522 | |
| 1523 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1524 which the lines are to be written. | |
| 1525 | |
| 1526 The '[ and '] marks have a special position: | |
| 1527 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1528 the new lines will be inserted. | |
| 1529 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1530 just read, the '] mark to the last line. | |
| 26 | 1531 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1532 mark is set to the first line that will be written, the '] mark to the last | |
| 1533 line. | |
| 7 | 1534 Careful: '[ and '] change when using commands that change the buffer. |
| 1535 | |
| 1536 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1537 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1538 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1539 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1540 work for files without a buffer (e.g., with ":r file"). |
| 1541 | |
| 1542 *gzip-example* | |
| 1543 Examples for reading and writing compressed files: > | |
| 1544 :augroup gzip | |
| 1545 : autocmd! | |
| 1546 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1547 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1548 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 1549 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
| 1550 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
| 1551 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1552 | |
| 1553 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1554 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1555 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1556 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1557 :augroup END | |
| 1558 | |
| 1559 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1560 ":autocmd!", for when the file is sourced twice. | |
| 1561 | |
| 1562 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1563 | |
| 1564 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1565 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1566 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1567 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1568 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1569 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1570 'modified' option. | |
| 1571 | |
| 1572 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1573 command. Use with care! If the Normal mode command is not finished, the user | |
| 1574 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1575 name). | |
| 1576 | |
| 1577 If you want the buffer to be unmodified after changing it, reset the | |
| 1578 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1579 instead of ":q!". | |
| 1580 | |
| 1581 *autocmd-nested* *E218* | |
| 16023 | 1582 By default, autocommands do not nest. For example, if you use ":e" or ":w" in |
| 1583 an autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 7 | 1584 those commands. If you do want this, use the "nested" flag for those commands |
| 1585 in which you want nesting. For example: > | |

1586 :autocmd FileChangedShell *.c ++nested e! |
| 7 | 1587 The nesting is limited to 10 levels to get out of recursive loops. |
| 1588 | |
| 1589 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1590 self-modifying command! This can be useful for an autocommand that should | |
| 1591 execute only once. | |
| 1592 | |
| 590 | 1593 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1594 modifier or the 'eventignore' option. | |
| 7 | 1595 |
| 1596 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1597 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1598 write (with ":write file" or with a filter command), if the same line is | |
| 1599 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1600 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1601 same file as was read, and makes a write command on just filtered lines write | |
| 1602 the same file as was read from the filter. For example, another way to write | |
| 1603 a compressed file: > | |
| 1604 | |
| 1605 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1606 :autocmd FileWritePost *.gz undo|set nobin | |
| 1607 < | |
| 1608 *autocommand-pattern* | |

| 1613 :autocmd BufRead .letter set tw=72 fo=2tcrq | |

| 1618 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1619 | |
| 1620 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1621 | |
| 1622 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1623 :autocmd BufLeave ?akefile* set include& | |
| 1624 | |

| 1626 | |
| 1627 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1628 | |
| 1629 Without the "1;" above, the search would start from wherever the file was | |

| 1632 *skeleton* *template* | |
| 1633 To read a skeleton (template) file when opening a new file: > | |

| 1639 To insert the current date and time in a *.html file when writing it: > | |
| 1640 | |
| 1641 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1642 :fun LastMod() | |
| 1643 : if line("$") > 20 | |
| 1644 : let l = 20 | |
| 1645 : else | |
| 1646 : let l = line("$") | |
| 1647 : endif | |
| 1648 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
| 1649 : \ strftime("%Y %b %d") | |
| 1650 :endfun | |
| 1651 | |
| 1652 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1653 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1654 same line after it) with the current date and time. Explanation: | |
| 1655 ks mark current position with mark 's' | |
| 1656 call LastMod() call the LastMod() function to do the work | |
| 1657 's return the cursor to the old position | |
| 1658 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1659 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1660 lines the ":s" command is executed to replace the existing date with the | |
| 1661 current one. The ":execute" command is used to be able to use an expression | |
| 1662 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1663 function. You can change its argument to get another date string. | |
| 1664 | |
| 1665 When entering :autocmd on the command-line, completion of events and command | |
| 1666 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1667 | |
| 1668 Vim executes all matching autocommands in the order that you specify them. | |
| 1669 It is recommended that your first autocommand be used for all files by using | |
| 1670 "*" as the file pattern. This means that you can define defaults you like | |
| 1671 here for any settings, and if there is another matching autocommand it will | |
| 1672 override these. But if there is no other matching autocommand, then at least | |
| 1673 your default settings are recovered (if entering this file from another for | |
| 1674 which autocommands did match). Note that "*" will also match files starting | |
| 1675 with ".", unlike Unix shells. | |
| 1676 | |
| 1677 *autocmd-searchpat* | |
| 1678 Autocommands do not change the current search patterns. Vim saves the current | |
| 1679 search patterns before executing autocommands then restores them after the | |
| 1680 autocommands finish. This means that autocommands do not affect the strings | |
| 1681 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1682 use search patterns normally, e.g., with the "n" command. | |
| 1683 If you want an autocommand to set the search pattern, such that it is used | |
| 1684 after the autocommand finishes, use the ":let @/ =" command. | |
| 1685 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1686 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1687 highlighting when starting Vim. | |
| 1688 | |
| 1689 *Cmd-event* | |
| 1690 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1691 do the file reading, writing or sourcing. This can be used when working with |
| 1692 a special kind of file, for example on a remote system. | |
| 7 | 1693 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1694 making it impossible to read or write the matching files! Make sure you test | |
| 1695 your autocommands properly. Best is to use a pattern that will never match a | |
| 1696 normal file name, for example "ftp://*". | |
| 1697 | |
| 1698 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1699 editing session. When recovering from the original file, Vim reads only those | |
| 1700 parts of a file that are not found in the swap file. Since that is not | |
| 1701 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1702 original file isn't needed for recovery. You might want to do this only when | |
| 1703 you expect the file to be modified. | |
| 1704 | |
| 1061 | 1705 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1706 and "++ff=" argument that are effective. These should be used for the command | |
| 1707 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1708 used, zero otherwise. | |

| 1713 11. Disabling autocommands *autocmd-disable* | |
| 1714 | |
| 1715 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1716 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1717 afterwards, using a |:try| block with |:finally|. | |
| 1718 | |
| 1719 *:noautocmd* *:noa* | |
| 1720 To disable autocommands for just one command use the ":noautocmd" command | |
| 1721 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1722 following command. Example: > | |
| 1723 | |
| 1724 :noautocmd w fname.gz | |
| 1725 | |
| 1726 This will write the file without triggering the autocommands defined by the | |
| 1727 gzip plugin. | |
| 1728 | |
| 16023 | 1729 Note that some autocommands are not triggered right away, but only later. |
| 1730 This specifically applies to |CursorMoved| and |TextChanged|. | |
