| 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 | 81 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
| 82 arguments are not expanded when the autocommand is defined. These will be | |
| 83 expanded when the Event is recognized, and the {cmd} is executed. The only | |
| 84 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
| 85 > | |
| 86 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
| 87 | |
| 88 Here Vim expands <sfile> to the name of the file containing this line. | |

99 augroup END |
| 7 | 100 |
| 101 If you don't want to remove all autocommands, you can instead use a variable | |
| 102 to ensure that Vim includes the autocommands only once: > | |
| 103 | |
| 104 :if !exists("autocommands_loaded") | |
| 105 : let autocommands_loaded = 1 | |
| 106 : au ... | |
| 107 :endif | |
| 108 | |
| 109 When the [group] argument is not given, Vim uses the current group (as defined | |
| 110 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
| 111 that [group] must have been defined before. You cannot define a new group | |
| 112 with ":au group ..."; use ":augroup" for that. | |
| 113 | |
| 114 While testing autocommands, you might find the 'verbose' option to be useful: > | |
| 115 :set verbose=9 | |
| 116 This setting makes Vim echo the autocommands as it executes them. | |
| 117 | |
| 118 When defining an autocommand in a script, it will be able to call functions | |
| 119 local to the script and use mappings local to the script. When the event is | |
| 120 triggered and the command executed, it will run in the context of the script | |
| 121 it was defined in. This matters if |<SID>| is used in a command. | |
| 122 | |
| 1621 | 123 When executing the commands, the message from one command overwrites a |
| 7 | 124 previous message. This is different from when executing the commands |
| 125 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
| 126 prompt. When one command outputs two messages this can happen anyway. | |
| 127 | |
| 128 ============================================================================== | |
| 129 3. Removing autocommands *autocmd-remove* | |
| 130 | |
| 131 :au[tocmd]! [group] {event} {pat} [nested] {cmd} | |
| 132 Remove all autocommands associated with {event} and | |
| 133 {pat}, and add the command {cmd}. See | |
| 134 |autocmd-nested| for [nested]. | |
| 135 | |
| 136 :au[tocmd]! [group] {event} {pat} | |
| 137 Remove all autocommands associated with {event} and | |
| 138 {pat}. | |
| 139 | |
| 140 :au[tocmd]! [group] * {pat} | |
| 141 Remove all autocommands associated with {pat} for all | |
| 142 events. | |
| 143 | |
| 144 :au[tocmd]! [group] {event} | |
| 145 Remove ALL autocommands for {event}. | |

154 group, it breaks plugins, syntax highlighting, etc. |
| 7 | 155 |
| 156 When the [group] argument is not given, Vim uses the current group (as defined | |
| 157 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
| 158 | |
| 159 ============================================================================== | |
| 160 4. Listing autocommands *autocmd-list* | |
| 161 | |
| 162 :au[tocmd] [group] {event} {pat} | |
| 163 Show the autocommands associated with {event} and | |
| 164 {pat}. | |
| 165 | |
| 166 :au[tocmd] [group] * {pat} | |
| 167 Show the autocommands associated with {pat} for all | |
| 168 events. | |
| 169 | |
| 170 :au[tocmd] [group] {event} | |
| 171 Show all autocommands for {event}. | |
| 172 | |
| 173 :au[tocmd] [group] Show all autocommands. | |
| 174 | |
| 175 If you provide the [group] argument, Vim lists only the autocommands for | |
| 176 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 177 argument behavior differs from that for defining and removing autocommands. | |
| 178 | |
| 40 | 179 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 180 or <buffer=N>. See |autocmd-buflocal|. | |
| 181 | |
| 500 | 182 *:autocmd-verbose* |
| 183 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 184 was last defined. Example: > | |
| 185 | |
| 186 :verbose autocmd BufEnter | |
| 187 FileExplorer BufEnter | |
| 856 | 188 * call s:LocalBrowse(expand("<amatch>")) |
| 500 | 189 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
| 190 < | |
| 191 See |:verbose-cmd| for more information. | |
| 192 | |
| 7 | 193 ============================================================================== |
| 194 5. Events *autocmd-events* *E215* *E216* | |
| 195 | |
| 579 | 196 You can specify a comma-separated list of event names. No white space can be |
| 197 used in this list. The command applies to all the events in the list. | |
| 198 | |
| 199 For READING FILES there are four kinds of events possible: | |
| 200 BufNewFile starting to edit a non-existent file | |
| 201 BufReadPre BufReadPost starting to edit an existing file | |
| 202 FilterReadPre FilterReadPost read the temp file with filter output | |
| 203 FileReadPre FileReadPost any other file read | |
| 204 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 205 "Post" events are both triggered, before and after reading the file. | |
| 206 | |
| 207 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 208 are not allowed to change the current buffer (you will get an error message if | |
| 209 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 210 | |
| 211 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 212 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 213 autocommands, this doesn't happen. | |
| 214 | |
| 215 You can use the 'eventignore' option to ignore a number of events or all | |
| 216 events. | |
| 7 | 217 *autocommand-events* *{event}* |
| 218 Vim recognizes the following events. Vim ignores the case of event names | |
| 219 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 220 | |

| 365 | |
| 366 The alphabetical list of autocommand events: *autocmd-events-abc* | |
| 367 | |
| 368 *BufCreate* *BufAdd* | |
| 369 BufAdd or BufCreate Just after creating a new buffer which is | |
| 370 added to the buffer list, or adding a buffer | |
| 371 to the buffer list. | |
| 372 Also used just after a buffer in the buffer | |
| 373 list has been renamed. | |
| 374 The BufCreate event is for historic reasons. | |
| 375 NOTE: When this autocommand is executed, the | |
| 376 current buffer "%" may be different from the | |
| 377 buffer being created "<afile>". | |
| 378 *BufDelete* | |
| 379 BufDelete Before deleting a buffer from the buffer list. | |
| 380 The BufUnload may be called first (if the | |
| 381 buffer was loaded). | |
| 382 Also used just before a buffer in the buffer | |
| 383 list is renamed. | |
| 384 NOTE: When this autocommand is executed, the | |
| 385 current buffer "%" may be different from the | |
| 1621 | 386 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 387 Don't change to another buffer, it will cause |
| 388 problems. | |
| 579 | 389 *BufEnter* |
| 390 BufEnter After entering a buffer. Useful for setting | |
| 391 options for a file type. Also executed when | |
| 392 starting to edit a buffer, after the | |
| 393 BufReadPost autocommands. | |
| 394 *BufFilePost* | |
| 395 BufFilePost After changing the name of the current buffer | |
| 396 with the ":file" or ":saveas" command. | |
| 625 | 397 *BufFilePre* |
| 579 | 398 BufFilePre Before changing the name of the current buffer |
| 399 with the ":file" or ":saveas" command. | |
| 400 *BufHidden* | |
| 401 BufHidden Just after a buffer has become hidden. That | |
| 402 is, when there are no longer windows that show | |
| 403 the buffer, but the buffer is not unloaded or | |
| 404 deleted. Not used for ":qa" or ":q" when | |
| 405 exiting Vim. | |
| 406 NOTE: When this autocommand is executed, the | |
| 407 current buffer "%" may be different from the | |
| 408 buffer being unloaded "<afile>". | |
| 409 *BufLeave* | |
| 410 BufLeave Before leaving to another buffer. Also when | |
| 411 leaving or closing the current window and the | |
| 412 new current window is not for the same buffer. | |
| 413 Not used for ":qa" or ":q" when exiting Vim. | |
| 414 *BufNew* | |
| 415 BufNew Just after creating a new buffer. Also used | |
| 416 just after a buffer has been renamed. When | |
| 417 the buffer is added to the buffer list BufAdd | |
| 418 will be triggered too. | |
| 419 NOTE: When this autocommand is executed, the | |
| 420 current buffer "%" may be different from the | |
| 421 buffer being created "<afile>". | |
| 7 | 422 *BufNewFile* |
| 423 BufNewFile When starting to edit a file that doesn't | |
| 424 exist. Can be used to read in a skeleton | |
| 425 file. | |
| 426 *BufRead* *BufReadPost* | |
| 427 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 428 reading the file into the buffer, before | |
| 429 executing the modelines. See |BufWinEnter| | |
| 430 for when you need to do something after | |
| 431 processing the modelines. | |
| 432 This does NOT work for ":r file". Not used | |
| 433 when the file doesn't exist. Also used after | |
| 434 successfully recovering a file. | |
| 3682 | 435 Also triggered for the filetypedetect group |
| 436 when executing ":filetype detect" and when | |
| 437 writing an unnamed buffer in a way that the | |
| 438 buffer gets a name. | |
| 625 | 439 *BufReadCmd* |
| 7 | 440 BufReadCmd Before starting to edit a new buffer. Should |
| 441 read the file into the buffer. |Cmd-event| | |
| 625 | 442 *BufReadPre* *E200* *E201* |
| 579 | 443 BufReadPre When starting to edit a new buffer, before |
| 444 reading the file into the buffer. Not used | |
| 445 if the file doesn't exist. | |
| 446 *BufUnload* | |
| 447 BufUnload Before unloading a buffer. This is when the | |
| 448 text in the buffer is going to be freed. This | |
| 449 may be after a BufWritePost and before a | |
| 450 BufDelete. Also used for all buffers that are | |
| 451 loaded when Vim is going to exit. | |
| 452 NOTE: When this autocommand is executed, the | |
| 453 current buffer "%" may be different from the | |
| 454 buffer being unloaded "<afile>". | |

458 event is not triggered. |
| 579 | 459 *BufWinEnter* |
| 460 BufWinEnter After a buffer is displayed in a window. This | |
| 461 can be when the buffer is loaded (after | |
| 1621 | 462 processing the modelines) or when a hidden |
| 579 | 463 buffer is displayed in a window (and is no |
| 1621 | 464 longer hidden). |
| 465 Does not happen for |:split| without | |
| 466 arguments, since you keep editing the same | |
| 467 buffer, or ":split" with a file that's already | |
| 1668 | 468 open in a window, because it re-uses an |
| 469 existing buffer. But it does happen for a | |
| 470 ":split" with the name of the current buffer, | |
| 471 since it reloads that buffer. | |

| 477 Not when it's still visible in another window. | |
| 478 Also triggered when exiting. It's triggered | |
| 479 before BufUnload or BufHidden. | |
| 480 NOTE: When this autocommand is executed, the | |
| 481 current buffer "%" may be different from the | |
| 482 buffer being unloaded "<afile>". | |

484 event is not triggered. |
| 579 | 485 *BufWipeout* |
| 486 BufWipeout Before completely deleting a buffer. The | |
| 487 BufUnload and BufDelete events may be called | |
| 488 first (if the buffer was loaded and was in the | |
| 489 buffer list). Also used just before a buffer | |
| 490 is renamed (also when it's not in the buffer | |
| 491 list). | |
| 492 NOTE: When this autocommand is executed, the | |
| 493 current buffer "%" may be different from the | |
| 494 buffer being deleted "<afile>". | |
| 1919 | 495 Don't change to another buffer, it will cause |
| 496 problems. | |
| 7 | 497 *BufWrite* *BufWritePre* |
| 498 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
| 499 *BufWriteCmd* | |
| 500 BufWriteCmd Before writing the whole buffer to a file. | |
| 501 Should do the writing of the file and reset | |
| 39 | 502 'modified' if successful, unless '+' is in |
| 503 'cpo' and writing to another file |cpo-+|. | |
| 504 The buffer contents should not be changed. | |
| 3082 | 505 When the command resets 'modified' the undo |
| 506 information is adjusted to mark older undo | |
| 507 states as 'modified', like |:write| does. | |
| 39 | 508 |Cmd-event| |
| 579 | 509 *BufWritePost* |
| 510 BufWritePost After writing the whole buffer to a file | |
| 511 (should undo the commands for BufWritePre). | |
| 6154 | 512 *CmdUndefined* |
| 513 CmdUndefined When a user command is used but it isn't | |
| 514 defined. Useful for defining a command only | |
| 515 when it's used. The pattern is matched | |
| 516 against the command name. Both <amatch> and | |
| 517 <afile> are set to the name of the command. | |
| 518 NOTE: Autocompletion won't work until the | |
| 519 command is defined. An alternative is to | |
| 520 always define the user command and have it | |
| 521 invoke an autoloaded function. See |autoload|. | |

| 3682 | 574 *CompleteDone* |
| 575 CompleteDone After Insert mode completion is done. Either | |
| 576 when something was completed or abandoning | |
| 577 completion. |ins-completion| | |
| 6909 | 578 The |v:completed_item| variable contains |
| 579 information about the completed item. | |
| 3682 | 580 |
| 579 | 581 *CursorHold* |
| 582 CursorHold When the user doesn't press a key for the time | |
| 583 specified with 'updatetime'. Not re-triggered | |
| 584 until the user has pressed a key (i.e. doesn't | |
| 585 fire every 'updatetime' ms if you leave Vim to | |
| 586 make some coffee. :) See |CursorHold-example| | |
| 587 for previewing tags. | |
| 588 This event is only triggered in Normal mode. | |
| 1154 | 589 It is not triggered when waiting for a command |
| 590 argument to be typed, or a movement after an | |
| 591 operator. | |
| 610 | 592 While recording the CursorHold event is not |
| 593 triggered. |q| | |
| 6259 | 594 *<CursorHold>* |
| 595 Internally the autocommand is triggered by the | |
| 596 <CursorHold> key. In an expression mapping | |
| 597 |getchar()| may see this character. | |
| 598 | |
| 579 | 599 Note: Interactive commands cannot be used for |
| 600 this event. There is no hit-enter prompt, | |
| 601 the screen is updated directly (when needed). | |
| 602 Note: In the future there will probably be | |
| 603 another option to set the time. | |
| 604 Hint: to force an update of the status lines | |
| 605 use: > | |
| 606 :let &ro = &ro | |
| 607 < {only on Amiga, Unix, Win32, MSDOS and all GUI | |
| 608 versions} | |
| 661 | 609 *CursorHoldI* |

| 620 an operator is pending. | |
| 667 | 621 For an example see |match-parens|. |

| 624 that is slow. | |
| 661 | 625 *CursorMovedI* |

| 641 *FileChangedRO* | |
| 642 FileChangedRO Before making the first change to a read-only | |
| 643 file. Can be used to check-out the file from | |
| 644 a source control system. Not triggered when | |
| 645 the change was caused by an autocommand. | |
| 646 This event is triggered when making the first | |
| 647 change in a buffer or the first change after | |
| 823 | 648 'readonly' was set, just before the change is |
| 649 applied to the text. | |
| 579 | 650 WARNING: If the autocommand moves the cursor |
| 651 the effect of the change is undefined. | |
| 819 | 652 *E788* |
| 653 It is not allowed to change to another buffer | |
| 654 here. You can reload the buffer but not edit | |
| 655 another one. | |

| 679 cancelled if there is a modified buffer that | |
| 680 isn't automatically saved, use |VimLeavePre| | |
| 681 for really exiting. | |
| 7 | 682 *FileChangedShell* |
| 683 FileChangedShell When Vim notices that the modification time of | |
| 684 a file has changed since editing started. | |
| 685 Also when the file attributes of the file | |
| 5908 | 686 change or when the size of the file changes. |
| 687 |timestamp| | |
| 7 | 688 Mostly triggered after executing a shell |
| 689 command, but also with a |:checktime| command | |
| 11473 | 690 or when gvim regains input focus. |
| 7 | 691 This autocommand is triggered for each changed |
| 692 file. It is not used when 'autoread' is set | |
| 693 and the buffer was not changed. If a | |
| 694 FileChangedShell autocommand is present the | |
| 695 warning message and prompt is not given. | |
| 179 | 696 The |v:fcs_reason| variable is set to indicate |
| 697 what happened and |v:fcs_choice| can be used | |
| 698 to tell Vim what to do next. | |
| 7 | 699 NOTE: When this autocommand is executed, the |
| 700 current buffer "%" may be different from the | |
| 11347 | 701 buffer that was changed, which is in "<afile>". |
| 7 | 702 NOTE: The commands must not change the current |
| 703 buffer, jump to another buffer or delete a | |

704 buffer. *E246* *E811* |
| 7 | 705 NOTE: This event never nests, to avoid an |
| 706 endless loop. This means that while executing | |
| 707 commands for the FileChangedShell event no | |
| 708 other FileChangedShell event will be | |
| 709 triggered. | |
| 766 | 710 *FileChangedShellPost* |
| 711 FileChangedShellPost After handling a file that was changed outside | |
| 712 of Vim. Can be used to update the statusline. | |
| 579 | 713 *FileEncoding* |
| 714 FileEncoding Obsolete. It still works and is equivalent | |
| 715 to |EncodingChanged|. | |
| 716 *FileReadCmd* | |
| 717 FileReadCmd Before reading a file with a ":read" command. | |
| 718 Should do the reading of the file. |Cmd-event| | |
| 719 *FileReadPost* | |
| 720 FileReadPost After reading a file with a ":read" command. | |
| 721 Note that Vim sets the '[ and '] marks to the | |
| 722 first and last line of the read. This can be | |
| 723 used to operate on the lines just read. | |
| 724 *FileReadPre* | |
| 725 FileReadPre Before reading a file with a ":read" command. | |
| 726 *FileType* | |
| 1154 | 727 FileType When the 'filetype' option has been set. The |
| 728 pattern is matched against the filetype. | |

| 579 | 733 See |filetypes|. |
| 734 *FileWriteCmd* | |
| 735 FileWriteCmd Before writing to a file, when not writing the | |
| 736 whole buffer. Should do the writing to the | |
| 737 file. Should not change the buffer. Use the | |
| 738 '[ and '] marks for the range of lines. | |
| 739 |Cmd-event| | |
| 740 *FileWritePost* | |

| 744 FileWritePre Before writing to a file, when not writing the | |
| 745 whole buffer. Use the '[ and '] marks for the | |
| 746 range of lines. | |
| 747 *FilterReadPost* | |
| 748 FilterReadPost After reading a file from a filter command. | |
| 749 Vim checks the pattern against the name of | |
| 750 the current buffer as with FilterReadPre. | |
| 751 Not triggered when 'shelltemp' is off. | |
| 752 *FilterReadPre* *E135* | |
| 753 FilterReadPre Before reading a file from a filter command. | |
| 754 Vim checks the pattern against the name of | |
| 755 the current buffer, not the name of the | |
| 756 temporary file that is the output of the | |
| 757 filter command. | |
| 758 Not triggered when 'shelltemp' is off. | |
| 759 *FilterWritePost* | |
| 760 FilterWritePost After writing a file for a filter command or | |
| 761 making a diff. | |
| 762 Vim checks the pattern against the name of | |

| 764 Not triggered when 'shelltemp' is off. | |
| 765 *FilterWritePre* | |
| 766 FilterWritePre Before writing a file for a filter command or | |
| 767 making a diff. | |
| 768 Vim checks the pattern against the name of | |
| 769 the current buffer, not the name of the | |
| 770 temporary file that is the output of the | |
| 771 filter command. | |
| 772 Not triggered when 'shelltemp' is off. | |
| 7 | 773 *FocusGained* |

| 775 version and a few console versions where this | |
| 776 can be detected. | |
| 777 *FocusLost* | |
| 778 FocusLost When Vim lost input focus. Only for the GUI | |
| 779 version and a few console versions where this | |
| 11 | 780 can be detected. May also happen when a |
| 781 dialog pops up. | |
| 7 | 782 *FuncUndefined* |
| 783 FuncUndefined When a user function is used but it isn't | |
| 784 defined. Useful for defining a function only | |
| 1154 | 785 when it's used. The pattern is matched |
| 786 against the function name. Both <amatch> and | |
| 787 <afile> are set to the name of the function. | |
| 6154 | 788 NOTE: When writing Vim scripts a better |
| 789 alternative is to use an autoloaded function. | |
| 161 | 790 See |autoload-functions|. |
| 579 | 791 *GUIEnter* |
| 792 GUIEnter After starting the GUI successfully, and after | |
| 793 opening the window. It is triggered before | |
| 794 VimEnter when using gvim. Can be used to | |
| 795 position the window from a .gvimrc file: > | |
| 796 :autocmd GUIEnter * winpos 100 50 | |
| 1154 | 797 < *GUIFailed* |
| 798 GUIFailed After starting the GUI failed. Vim may | |
| 799 continue to run in the terminal, if possible | |
| 800 (only on Unix and alikes, when connecting the | |
| 801 X server fails). You may want to quit Vim: > | |
| 802 :autocmd GUIFailed * qall | |
| 579 | 803 < *InsertChange* |
| 804 InsertChange When typing <Insert> while in Insert or | |
| 805 Replace mode. The |v:insertmode| variable | |
| 806 indicates the new mode. | |
| 807 Be careful not to move the cursor or do | |
| 808 anything else that the user does not expect. | |
| 2845 | 809 *InsertCharPre* |
| 810 InsertCharPre When a character is typed in Insert mode, | |
| 811 before inserting the char. | |
| 812 The |v:char| variable indicates the char typed | |
| 813 and can be changed during the event to insert | |
| 814 a different character. When |v:char| is set | |
| 815 to more than one character this text is | |
| 816 inserted literally. | |
| 817 It is not allowed to change the text |textlock|. | |
| 818 The event is not triggered when 'paste' is | |
| 13437 | 819 set. {only with the +eval feature} |
| 579 | 820 *InsertEnter* |
| 1154 | 821 InsertEnter Just before starting Insert mode. Also for |
| 822 Replace mode and Virtual Replace mode. The | |
| 579 | 823 |v:insertmode| variable indicates the mode. |
| 4448 | 824 Be careful not to do anything else that the |
| 825 user does not expect. | |
| 826 The cursor is restored afterwards. If you do | |
| 827 not want that set |v:char| to a non-empty | |
| 828 string. | |
| 579 | 829 *InsertLeave* |
| 830 InsertLeave When leaving Insert mode. Also when using | |
| 831 CTRL-O |i_CTRL-O|. But not for |i_CTRL-C|. | |
| 832 *MenuPopup* | |
| 833 MenuPopup Just before showing the popup menu (under the | |
| 834 right mouse button). Useful for adjusting the | |
| 835 menu for what is under the cursor or mouse | |
| 836 pointer. | |
| 837 The pattern is matched against a single | |
| 838 character representing the mode: | |
| 839 n Normal | |
| 840 v Visual | |
| 841 o Operator-pending | |
| 842 i Insert | |
| 843 | 843 c Command line |
| 6935 | 844 *OptionSet* |
| 845 OptionSet After setting an option. The pattern is | |
| 846 matched against the long option name. | |
| 847 The |v:option_old| variable indicates the | |
| 848 old option value, |v:option_new| variable | |
| 849 indicates the newly set value, the | |
| 850 |v:option_type| variable indicates whether | |
| 851 it's global or local scoped and |<amatch>| | |
| 852 indicates what option has been set. | |
| 853 | |
| 854 Is not triggered on startup and for the 'key' | |
| 855 option for obvious reasons. | |

900 Also see |ExitPre|. |
| 579 | 901 *RemoteReply* |
| 902 RemoteReply When a reply from a Vim that functions as | |
| 1154 | 903 server was received |server2client()|. The |
| 904 pattern is matched against the {serverid}. | |
| 579 | 905 <amatch> is equal to the {serverid} from which |
| 906 the reply was sent, and <afile> is the actual | |
| 907 reply string. | |
| 908 Note that even if an autocommand is defined, | |
| 909 the reply should be read with |remote_read()| | |
| 910 to consume it. | |
| 911 *SessionLoadPost* | |
| 912 SessionLoadPost After loading the session file created using | |
| 913 the |:mksession| command. | |
| 724 | 914 *ShellCmdPost* |
| 915 ShellCmdPost After executing a shell command with |:!cmd|, | |
| 916 |:shell|, |:make| and |:grep|. Can be used to | |
| 917 check for any changed files. | |
| 918 *ShellFilterPost* | |
| 919 ShellFilterPost After executing a shell command with | |
| 920 ":{range}!cmd", ":w !cmd" or ":r !cmd". | |
| 921 Can be used to check for any changed files. | |
| 716 | 922 *SourcePre* |
| 923 SourcePre Before sourcing a Vim script. |:source| | |
| 1061 | 924 <afile> is the name of the file being sourced. |
| 925 *SourceCmd* | |
| 926 SourceCmd When sourcing a Vim script. |:source| | |
| 927 <afile> is the name of the file being sourced. | |
| 928 The autocommand must source this file. | |
| 929 |Cmd-event| | |
| 650 | 930 *SpellFileMissing* |
| 931 SpellFileMissing When trying to load a spell checking file and | |
| 1061 | 932 it can't be found. The pattern is matched |
| 933 against the language. <amatch> is the | |
| 934 language, 'encoding' also matters. See | |
| 650 | 935 |spell-SpellFileMissing|. |
| 579 | 936 *StdinReadPost* |
| 937 StdinReadPost After reading from the stdin into the buffer, | |
| 938 before executing the modelines. Only used | |
| 939 when the "-" argument was used when Vim was | |
| 940 started |--|. | |
| 941 *StdinReadPre* | |
| 942 StdinReadPre Before reading from stdin into the buffer. | |
| 943 Only used when the "-" argument was used when | |
| 944 Vim was started |--|. | |
| 945 *SwapExists* | |
| 946 SwapExists Detected an existing swap file when starting | |
| 947 to edit a file. Only when it is possible to | |
| 948 select a way to handle the situation, when Vim | |
| 949 would ask the user what to do. | |
| 950 The |v:swapname| variable holds the name of | |
| 590 | 951 the swap file found, <afile> the file being |
| 952 edited. |v:swapcommand| may contain a command | |
| 953 to be executed in the opened file. | |
| 954 The commands should set the |v:swapchoice| | |
| 955 variable to a string with one character to | |
| 956 tell Vim what should be done next: | |
| 579 | 957 'o' open read-only |
| 958 'e' edit the file anyway | |
| 959 'r' recover | |
| 960 'd' delete the swap file | |
| 961 'q' quit, don't edit the file | |
| 962 'a' abort, like hitting CTRL-C | |
| 963 When set to an empty string the user will be | |
| 964 asked, as if there was no SwapExists autocmd. | |
| 1919 | 965 *E812* |
| 966 It is not allowed to change to another buffer, | |
| 967 change a buffer name or change directory | |
| 968 here. | |
| 13437 | 969 {only available with the +eval feature} |
| 579 | 970 *Syntax* |
| 1154 | 971 Syntax When the 'syntax' option has been set. The |
| 972 pattern is matched against the syntax name. | |
| 579 | 973 <afile> can be used for the name of the file |
| 974 where this option was set, and <amatch> for | |
| 975 the new value of 'syntax'. | |
| 976 See |:syn-on|. | |

| 1117 6. Patterns *autocmd-patterns* *{pat}* | |
| 1118 | |
| 6741 | 1119 The {pat} argument can be a comma separated list. This works as if the |
| 1120 command was given with each pattern separately. Thus this command: > | |
| 1121 :autocmd BufRead *.txt,*.info set et | |
| 1122 Is equivalent to: > | |
| 1123 :autocmd BufRead *.txt set et | |
| 1124 :autocmd BufRead *.info set et | |
| 1125 | |
| 7 | 1126 The file pattern {pat} is tested for a match against the file name in one of |
| 1127 two ways: | |
| 1128 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1129 the tail part of the file name (without its leading directory path). | |

1132 it to a full path and resolving symbolic links). |
| 7 | 1133 |
| 40 | 1134 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1135 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1136 of a buffer. | |
| 1137 | |
| 7 | 1138 Examples: > |
| 1139 :autocmd BufRead *.txt set et | |
| 1140 Set the 'et' option for all text files. > | |
| 1141 | |
| 1142 :autocmd BufRead /vim/src/*.c set cindent | |
| 1143 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1144 | |
| 1145 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1146 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1147 you start editing "/tmp/test.c", this autocommand will match. | |
| 1148 | |
| 1149 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1150 the first character. Example: > | |
| 1151 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1152 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1153 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1154 | |
| 1155 | |
| 1156 The file name that the pattern is matched against is after expanding | |
| 1621 | 1157 wildcards. Thus if you issue this command: > |
| 7 | 1158 :e $ROOTDIR/main.$EXT |
| 1159 The argument is first expanded to: > | |
| 1160 /usr/root/main.py | |
| 1161 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1162 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1163 expect. | |
| 1164 | |
| 1165 | |
| 1166 Environment variables can be used in a pattern: > | |
| 1167 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1168 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1169 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1170 :autocmd BufRead ~archive/* set readonly | |
| 1171 The environment variable is expanded when the autocommand is defined, not when | |
| 1172 the autocommand is executed. This is different from the command! | |
| 1173 | |
| 1174 *file-pattern* | |
| 1175 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1176 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1177 separators |
| 7 | 1178 ? matches any single character |
| 1179 \? matches a '?' | |
| 1180 . matches a '.' | |
| 1181 ~ matches a '~' | |
| 1182 , separates patterns | |
| 1183 \, matches a ',' | |
| 1184 { } like \( \) in a |pattern| | |
| 1185 , inside { }: like \| in a |pattern| | |

| 1193 Note that for all systems the '/' character is used for path separator (even | |

| 1195 in a pattern and to make the autocommands portable across different systems. | |

| 40 | 1200 *autocmd-changes* |
| 7 | 1201 Matching with the pattern is done when an event is triggered. Changing the |
| 1202 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1203 change which autocommands will be executed. Example: > | |
| 1204 | |
| 1205 au BufEnter *.foo bdel | |
| 1206 au BufEnter *.foo set modified | |
| 1207 | |
| 1208 This will delete the current buffer and then set 'modified' in what has become | |
| 1209 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1210 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1211 buffer at the moment the event was triggered. | |
| 1212 | |
| 40 | 1213 However, buffer-local autocommands will not be executed for a buffer that has |
| 1214 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1215 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1216 still executed. | |
| 1217 | |
| 7 | 1218 ============================================================================== |
| 856 | 1219 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1220 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1221 |
| 1222 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1223 if the buffer does not have a name and when the name does not match a specific | |
| 1224 pattern. But it also means they must be explicitly added to each buffer. | |
| 1225 | |
| 1226 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1227 <buffer> current buffer | |
| 1228 <buffer=99> buffer number 99 | |
| 1229 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1230 |<abuf>| | |
| 1231 | |
| 1232 Examples: > | |
| 1233 :au CursorHold <buffer> echo 'hold' | |
| 1234 :au CursorHold <buffer=33> echo 'hold' | |

1235 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1236 |
| 1237 All the commands for autocommands also work with buffer-local autocommands, | |
| 1238 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1239 :au! * <buffer> " remove buffer-local autocommands for |
| 1240 " current buffer | |
| 1241 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1242 " buffer #33 | |
| 1621 | 1243 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1244 " buffers |
| 1245 :au * <buffer> " list buffer-local autocommands for | |
| 1246 " current buffer | |
| 40 | 1247 |
| 1248 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1249 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1250 number of the current buffer. You will see this when listing autocommands, | |
| 1251 for example. | |
| 1252 | |
| 1253 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1254 as follows: > | |
| 1255 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1256 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1257 | |
| 1258 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1259 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1260 unlisted, the autocommands are still present. In order to see the removal of | |
| 1261 buffer-local autocommands: > | |
| 1262 :set verbose=6 | |
| 1263 | |
| 1264 It is not possible to define buffer-local autocommands for a non-existent | |
| 1265 buffer. | |
| 1266 | |
| 1267 ============================================================================== | |
| 1268 8. Groups *autocmd-groups* | |
| 7 | 1269 |
| 1270 Autocommands can be put together in a group. This is useful for removing or | |
| 1271 executing a group of autocommands. For example, all the autocommands for | |
| 1272 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1273 ":doautoall highlight BufRead" when the GUI starts. | |
| 1274 | |
| 1275 When no specific group is selected, Vim uses the default group. The default | |
| 1276 group does not have a name. You cannot execute the autocommands from the | |
| 1277 default group separately; you can execute them only by executing autocommands | |
| 1278 for all groups. | |
| 1279 | |
| 1280 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1281 for all groups. The group only matters when executing autocommands with | |
| 1282 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1283 | |
| 1284 The group name can contain any characters except white space. The group name | |
| 1285 "end" is reserved (also in uppercase). | |
| 1286 | |
| 1287 The group name is case sensitive. Note that this is different from the event | |
| 1288 name! | |
| 1289 | |
| 1290 *:aug* *:augroup* | |
| 1291 :aug[roup] {name} Define the autocmd group name for the | |
| 1292 following ":autocmd" commands. The name "end" | |
| 1293 or "END" selects the default group. | |

| 1305 To enter autocommands for a specific group, use this method: | |
| 1306 1. Select the group with ":augroup {name}". | |
| 1307 2. Delete any old autocommands with ":au!". | |
| 1308 3. Define the autocommands. | |
| 1309 4. Go back to the default group with "augroup END". | |
| 1310 | |
| 1311 Example: > | |
| 1312 :augroup uncompress | |
| 1313 : au! | |
| 1314 : au BufEnter *.gz %!gunzip | |
| 1315 :augroup END | |
| 1316 | |
| 1317 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1318 .vimrc file again). | |
| 1319 | |
| 1320 ============================================================================== | |
| 40 | 1321 9. Executing autocommands *autocmd-execute* |
| 7 | 1322 |
| 1323 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1324 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1325 (e.g., the file pattern match was wrong). | |
| 1326 | |
| 1327 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1328 option will not cause any commands to be executed. | |
| 1329 | |
| 1330 *:do* *:doau* *:doautocmd* *E217* | |
| 3356 | 1331 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1332 Apply the autocommands matching [fname] (default: |
| 1333 current file name) for {event} to the current buffer. | |
| 1334 You can use this when the current file name does not | |
| 1335 match the right pattern, after changing settings, or | |
| 1336 to execute autocommands for a certain event. | |
| 1337 It's possible to use this inside an autocommand too, | |
| 1338 so you can base the autocommands for one extension on | |
| 1339 another extension. Example: > | |
| 3224 | 1340 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1341 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1342 < Be careful to avoid endless loops. See |
| 1343 |autocmd-nested|. | |
| 1344 | |
| 1345 When the [group] argument is not given, Vim executes | |
| 1346 the autocommands for all groups. When the [group] | |
| 1347 argument is included, Vim executes only the matching | |
| 1348 autocommands for that group. Note: if you use an | |
| 1349 undefined group name, Vim gives you an error message. | |
| 3350 | 1350 *<nomodeline>* |
| 1351 After applying the autocommands the modelines are | |
| 1352 processed, so that their settings overrule the | |
| 1353 settings from autocommands, like what happens when | |
| 1354 editing a file. This is skipped when the <nomodeline> | |
| 1355 argument is present. You probably want to use | |
| 1356 <nomodeline> for events that are not used when loading | |
| 1357 a buffer, such as |User|. | |

1364 loaded buffer. Note that [fname] is used to select |
| 7 | 1365 the autocommands, not the buffers to which they are |
| 1366 applied. | |
| 1367 Careful: Don't use this for autocommands that delete a | |
| 1368 buffer, change to another buffer or change the | |
| 1369 contents of a buffer; the result is unpredictable. | |
| 1370 This command is intended for autocommands that set | |
| 1371 options, change highlighting, and things like that. | |
| 1372 | |
| 1373 ============================================================================== | |
| 40 | 1374 10. Using autocommands *autocmd-use* |
| 7 | 1375 |
| 1376 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1377 of these sets for a write command: | |
| 1378 | |
| 1379 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1380 FilterWritePre FilterWritePost writing to filter temp file | |
| 1381 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1382 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1383 | |
| 1384 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1385 writing. No further writing is done and the other events are not triggered. | |
| 1386 |Cmd-event| | |
| 1387 | |
| 1388 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1389 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1390 the side effect of changing the buffer. | |
| 1391 | |
| 1392 Before executing the autocommands, the buffer from which the lines are to be | |
| 1393 written temporarily becomes the current buffer. Unless the autocommands | |
| 1394 change the current buffer or delete the previously current buffer, the | |
| 1395 previously current buffer is made the current buffer again. | |
| 1396 | |
| 1397 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1398 which the lines are to be written. | |
| 1399 | |
| 1400 The '[ and '] marks have a special position: | |
| 1401 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1402 the new lines will be inserted. | |
| 1403 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1404 just read, the '] mark to the last line. | |
| 26 | 1405 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1406 mark is set to the first line that will be written, the '] mark to the last | |
| 1407 line. | |
| 7 | 1408 Careful: '[ and '] change when using commands that change the buffer. |
| 1409 | |
| 1410 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1411 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1412 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1413 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1414 work for files without a buffer (e.g., with ":r file"). |
| 1415 | |
| 1416 *gzip-example* | |
| 1417 Examples for reading and writing compressed files: > | |
| 1418 :augroup gzip | |
| 1419 : autocmd! | |
| 1420 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1421 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1422 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 1423 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
| 1424 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
| 1425 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1426 | |
| 1427 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1428 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1429 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1430 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1431 :augroup END | |
| 1432 | |
| 1433 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1434 ":autocmd!", for when the file is sourced twice. | |
| 1435 | |
| 1436 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1437 | |
| 1438 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1439 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1440 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1441 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1442 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1443 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1444 'modified' option. | |
| 1445 | |
| 1446 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1447 command. Use with care! If the Normal mode command is not finished, the user | |
| 1448 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1449 name). | |
| 1450 | |
| 1451 If you want the buffer to be unmodified after changing it, reset the | |
| 1452 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1453 instead of ":q!". | |
| 1454 | |
| 1455 *autocmd-nested* *E218* | |
| 1456 By default, autocommands do not nest. If you use ":e" or ":w" in an | |
| 1457 autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 1458 those commands. If you do want this, use the "nested" flag for those commands | |
| 1459 in which you want nesting. For example: > | |
| 1460 :autocmd FileChangedShell *.c nested e! | |
| 1461 The nesting is limited to 10 levels to get out of recursive loops. | |
| 1462 | |
| 1463 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1464 self-modifying command! This can be useful for an autocommand that should | |
| 1465 execute only once. | |
| 1466 | |
| 590 | 1467 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1468 modifier or the 'eventignore' option. | |
| 7 | 1469 |
| 1470 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1471 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1472 write (with ":write file" or with a filter command), if the same line is | |
| 1473 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1474 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1475 same file as was read, and makes a write command on just filtered lines write | |
| 1476 the same file as was read from the filter. For example, another way to write | |
| 1477 a compressed file: > | |
| 1478 | |
| 1479 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1480 :autocmd FileWritePost *.gz undo|set nobin | |
| 1481 < | |
| 1482 *autocommand-pattern* | |
| 1483 You can specify multiple patterns, separated by commas. Here are some | |
| 1484 examples: > | |
| 1485 | |
| 1486 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
| 1487 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
| 1488 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
| 1489 :autocmd BufLeave .letter set dict= | |
| 1490 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
| 1491 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
| 1492 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1493 | |
| 1494 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1495 | |
| 1496 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1497 :autocmd BufLeave ?akefile* set include& | |
| 1498 | |
| 1499 To always start editing C files at the first function: > | |
| 1500 | |
| 1501 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1502 | |
| 1503 Without the "1;" above, the search would start from wherever the file was | |
| 1504 entered, rather than from the start of the file. | |
| 1505 | |
| 1506 *skeleton* *template* | |
| 1507 To read a skeleton (template) file when opening a new file: > | |
| 1508 | |
| 1509 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
| 1510 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
| 1511 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
| 1512 | |
| 1513 To insert the current date and time in a *.html file when writing it: > | |
| 1514 | |
| 1515 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1516 :fun LastMod() | |
| 1517 : if line("$") > 20 | |
| 1518 : let l = 20 | |
| 1519 : else | |
| 1520 : let l = line("$") | |
| 1521 : endif | |
| 1522 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
| 1523 : \ strftime("%Y %b %d") | |
| 1524 :endfun | |
| 1525 | |
| 1526 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1527 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1528 same line after it) with the current date and time. Explanation: | |
| 1529 ks mark current position with mark 's' | |
| 1530 call LastMod() call the LastMod() function to do the work | |
| 1531 's return the cursor to the old position | |
| 1532 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1533 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1534 lines the ":s" command is executed to replace the existing date with the | |
| 1535 current one. The ":execute" command is used to be able to use an expression | |
| 1536 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1537 function. You can change its argument to get another date string. | |
| 1538 | |
| 1539 When entering :autocmd on the command-line, completion of events and command | |
| 1540 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1541 | |
| 1542 Vim executes all matching autocommands in the order that you specify them. | |
| 1543 It is recommended that your first autocommand be used for all files by using | |
| 1544 "*" as the file pattern. This means that you can define defaults you like | |
| 1545 here for any settings, and if there is another matching autocommand it will | |
| 1546 override these. But if there is no other matching autocommand, then at least | |
| 1547 your default settings are recovered (if entering this file from another for | |
| 1548 which autocommands did match). Note that "*" will also match files starting | |
| 1549 with ".", unlike Unix shells. | |
| 1550 | |
| 1551 *autocmd-searchpat* | |
| 1552 Autocommands do not change the current search patterns. Vim saves the current | |
| 1553 search patterns before executing autocommands then restores them after the | |
| 1554 autocommands finish. This means that autocommands do not affect the strings | |
| 1555 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1556 use search patterns normally, e.g., with the "n" command. | |
| 1557 If you want an autocommand to set the search pattern, such that it is used | |
| 1558 after the autocommand finishes, use the ":let @/ =" command. | |
| 1559 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1560 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1561 highlighting when starting Vim. | |
| 1562 | |
| 1563 *Cmd-event* | |
| 1564 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1565 do the file reading, writing or sourcing. This can be used when working with |
| 1566 a special kind of file, for example on a remote system. | |
| 7 | 1567 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1568 making it impossible to read or write the matching files! Make sure you test | |
| 1569 your autocommands properly. Best is to use a pattern that will never match a | |
| 1570 normal file name, for example "ftp://*". | |
| 1571 | |
| 1572 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1573 editing session. When recovering from the original file, Vim reads only those | |
| 1574 parts of a file that are not found in the swap file. Since that is not | |
| 1575 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1576 original file isn't needed for recovery. You might want to do this only when | |
| 1577 you expect the file to be modified. | |
| 1578 | |
| 1061 | 1579 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1580 and "++ff=" argument that are effective. These should be used for the command | |
| 1581 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1582 used, zero otherwise. | |

| 1587 11. Disabling autocommands *autocmd-disable* | |
| 1588 | |
| 1589 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1590 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1591 afterwards, using a |:try| block with |:finally|. | |
| 1592 | |
| 1593 *:noautocmd* *:noa* | |
| 1594 To disable autocommands for just one command use the ":noautocmd" command | |
| 1595 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1596 following command. Example: > | |
| 1597 | |
| 1598 :noautocmd w fname.gz | |
| 1599 | |
| 1600 This will write the file without triggering the autocommands defined by the | |
| 1601 gzip plugin. | |
