| 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. | |

| 40 | 71 The special pattern <buffer> or <buffer=N> defines a buffer-local autocommand. |
| 72 See |autocmd-buflocal|. | |
| 73 | |
| 23164 | 74 If the `:autocmd` is in Vim9 script (a script that starts with `:vim9script` |
| 75 and in a `:def` function) then {cmd} will be executed as in Vim9 | |
| 22958 | 76 script. Thus this depends on where the autocmd is defined, not where it is |
| 77 triggered. | |
| 78 | |
| 25619 | 79 {cmd} can be a block, like with `:command`, see |:command-repl|. Example: > |

| 7 | 98 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
| 99 arguments are not expanded when the autocommand is defined. These will be | |
| 100 expanded when the Event is recognized, and the {cmd} is executed. The only | |
| 101 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
| 102 > | |
| 103 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
| 104 | |
| 105 Here Vim expands <sfile> to the name of the file containing this line. | |

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

| 174 When the [group] argument is not given, Vim uses the current group (as defined | |

| 178 4. Listing autocommands *autocmd-list* | |
| 179 | |
| 180 :au[tocmd] [group] {event} {pat} | |
| 181 Show the autocommands associated with {event} and | |
| 182 {pat}. | |
| 183 | |
| 184 :au[tocmd] [group] * {pat} | |
| 185 Show the autocommands associated with {pat} for all | |
| 186 events. | |
| 187 | |
| 188 :au[tocmd] [group] {event} | |
| 189 Show all autocommands for {event}. | |
| 190 | |
| 191 :au[tocmd] [group] Show all autocommands. | |
| 192 | |
| 193 If you provide the [group] argument, Vim lists only the autocommands for | |
| 194 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 195 argument behavior differs from that for defining and removing autocommands. | |
| 196 | |
| 40 | 197 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 198 or <buffer=N>. See |autocmd-buflocal|. | |
| 199 | |
| 500 | 200 *:autocmd-verbose* |
| 201 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 202 was last defined. Example: > | |
| 203 | |
| 204 :verbose autocmd BufEnter | |
| 205 FileExplorer BufEnter | |
| 856 | 206 * call s:LocalBrowse(expand("<amatch>")) |

| 579 | 214 You can specify a comma-separated list of event names. No white space can be |
| 215 used in this list. The command applies to all the events in the list. | |
| 216 | |
| 217 For READING FILES there are four kinds of events possible: | |
| 218 BufNewFile starting to edit a non-existent file | |
| 219 BufReadPre BufReadPost starting to edit an existing file | |
| 220 FilterReadPre FilterReadPost read the temp file with filter output | |
| 221 FileReadPre FileReadPost any other file read | |
| 222 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 223 "Post" events are both triggered, before and after reading the file. | |
| 224 | |
| 225 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 226 are not allowed to change the current buffer (you will get an error message if | |
| 227 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 228 | |
| 229 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 230 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 231 autocommands, this doesn't happen. | |
| 232 | |
| 233 You can use the 'eventignore' option to ignore a number of events or all | |
| 234 events. | |
| 7 | 235 *autocommand-events* *{event}* |
| 236 Vim recognizes the following events. Vim ignores the case of event names | |
| 237 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 238 | |
| 579 | 239 First an overview by function with a short explanation. Then the list |
| 843 | 240 alphabetically with full explanations |autocmd-events-abc|. |

413 during startup. |
| 579 | 414 The BufCreate event is for historic reasons. |
| 415 NOTE: When this autocommand is executed, the | |
| 416 current buffer "%" may be different from the | |
| 417 buffer being created "<afile>". | |
| 418 *BufDelete* | |
| 419 BufDelete Before deleting a buffer from the buffer list. | |
| 420 The BufUnload may be called first (if the | |
| 421 buffer was loaded). | |
| 422 Also used just before a buffer in the buffer | |
| 423 list is renamed. | |
| 424 NOTE: When this autocommand is executed, the | |
| 425 current buffer "%" may be different from the | |
| 1621 | 426 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 427 Don't change to another buffer, it will cause |
| 428 problems. | |
| 579 | 429 *BufEnter* |
| 430 BufEnter After entering a buffer. Useful for setting | |
| 431 options for a file type. Also executed when | |
| 432 starting to edit a buffer, after the | |
| 433 BufReadPost autocommands. | |
| 434 *BufFilePost* | |
| 435 BufFilePost After changing the name of the current buffer | |
| 436 with the ":file" or ":saveas" command. | |
| 625 | 437 *BufFilePre* |
| 579 | 438 BufFilePre Before changing the name of the current buffer |
| 439 with the ":file" or ":saveas" command. | |
| 440 *BufHidden* | |
| 17261 | 441 BufHidden Just before a buffer becomes hidden. That is, |
| 442 when there are no longer windows that show | |
| 579 | 443 the buffer, but the buffer is not unloaded or |
| 444 deleted. Not used for ":qa" or ":q" when | |
| 445 exiting Vim. | |
| 446 NOTE: When this autocommand is executed, the | |
| 447 current buffer "%" may be different from the | |
| 448 buffer being unloaded "<afile>". | |
| 449 *BufLeave* | |
| 450 BufLeave Before leaving to another buffer. Also when | |
| 451 leaving or closing the current window and the | |
| 452 new current window is not for the same buffer. | |
| 453 Not used for ":qa" or ":q" when exiting Vim. | |
| 454 *BufNew* | |
| 455 BufNew Just after creating a new buffer. Also used | |
| 456 just after a buffer has been renamed. When | |
| 457 the buffer is added to the buffer list BufAdd | |
| 458 will be triggered too. | |
| 459 NOTE: When this autocommand is executed, the | |
| 460 current buffer "%" may be different from the | |
| 461 buffer being created "<afile>". | |
| 7 | 462 *BufNewFile* |
| 463 BufNewFile When starting to edit a file that doesn't | |
| 464 exist. Can be used to read in a skeleton | |
| 465 file. | |
| 466 *BufRead* *BufReadPost* | |
| 467 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 468 reading the file into the buffer, before | |
| 469 executing the modelines. See |BufWinEnter| | |
| 470 for when you need to do something after | |
| 471 processing the modelines. | |
| 472 This does NOT work for ":r file". Not used | |
| 473 when the file doesn't exist. Also used after | |
| 474 successfully recovering a file. | |
| 3682 | 475 Also triggered for the filetypedetect group |
| 476 when executing ":filetype detect" and when | |
| 477 writing an unnamed buffer in a way that the | |
| 478 buffer gets a name. | |
| 625 | 479 *BufReadCmd* |
| 7 | 480 BufReadCmd Before starting to edit a new buffer. Should |
| 481 read the file into the buffer. |Cmd-event| | |
| 625 | 482 *BufReadPre* *E200* *E201* |
| 579 | 483 BufReadPre When starting to edit a new buffer, before |
| 484 reading the file into the buffer. Not used | |
| 485 if the file doesn't exist. | |
| 486 *BufUnload* | |
| 487 BufUnload Before unloading a buffer. This is when the | |
| 488 text in the buffer is going to be freed. This | |
| 489 may be after a BufWritePost and before a | |
| 490 BufDelete. Also used for all buffers that are | |
| 491 loaded when Vim is going to exit. | |
| 492 NOTE: When this autocommand is executed, the | |
| 493 current buffer "%" may be different from the | |
| 494 buffer being unloaded "<afile>". | |

498 event is not triggered. |
| 579 | 499 *BufWinEnter* |
| 500 BufWinEnter After a buffer is displayed in a window. This | |
| 501 can be when the buffer is loaded (after | |
| 1621 | 502 processing the modelines) or when a hidden |
| 579 | 503 buffer is displayed in a window (and is no |
| 1621 | 504 longer hidden). |
| 505 Does not happen for |:split| without | |
| 506 arguments, since you keep editing the same | |
| 507 buffer, or ":split" with a file that's already | |
| 1668 | 508 open in a window, because it re-uses an |
| 509 existing buffer. But it does happen for a | |
| 510 ":split" with the name of the current buffer, | |
| 511 since it reloads that buffer. | |

514 commands won't work. Use |TerminalOpen| instead. |
| 579 | 515 *BufWinLeave* |
| 516 BufWinLeave Before a buffer is removed from a window. | |
| 517 Not when it's still visible in another window. | |
| 518 Also triggered when exiting. It's triggered | |
| 519 before BufUnload or BufHidden. | |
| 520 NOTE: When this autocommand is executed, the | |
| 521 current buffer "%" may be different from the | |
| 522 buffer being unloaded "<afile>". | |

524 event is not triggered. |
| 579 | 525 *BufWipeout* |
| 526 BufWipeout Before completely deleting a buffer. The | |
| 527 BufUnload and BufDelete events may be called | |
| 528 first (if the buffer was loaded and was in the | |
| 529 buffer list). Also used just before a buffer | |
| 530 is renamed (also when it's not in the buffer | |
| 531 list). | |
| 532 NOTE: When this autocommand is executed, the | |
| 533 current buffer "%" may be different from the | |
| 534 buffer being deleted "<afile>". | |
| 1919 | 535 Don't change to another buffer, it will cause |
| 536 problems. | |
| 7 | 537 *BufWrite* *BufWritePre* |
| 538 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
| 539 *BufWriteCmd* | |
| 540 BufWriteCmd Before writing the whole buffer to a file. | |
| 541 Should do the writing of the file and reset | |
| 39 | 542 'modified' if successful, unless '+' is in |
| 543 'cpo' and writing to another file |cpo-+|. | |
| 544 The buffer contents should not be changed. | |
| 3082 | 545 When the command resets 'modified' the undo |
| 546 information is adjusted to mark older undo | |
| 547 states as 'modified', like |:write| does. | |
| 39 | 548 |Cmd-event| |
| 579 | 549 *BufWritePost* |
| 550 BufWritePost After writing the whole buffer to a file | |
| 551 (should undo the commands for BufWritePre). | |
| 6154 | 552 *CmdUndefined* |
| 553 CmdUndefined When a user command is used but it isn't | |
| 554 defined. Useful for defining a command only | |
| 555 when it's used. The pattern is matched | |
| 556 against the command name. Both <amatch> and | |
| 557 <afile> are set to the name of the command. | |
| 558 NOTE: Autocompletion won't work until the | |
| 559 command is defined. An alternative is to | |
| 560 always define the user command and have it | |
| 561 invoke an autoloaded function. See |autoload|. | |

| 658 make some coffee. :) See |CursorHold-example| | |
| 659 for previewing tags. | |
| 660 This event is only triggered in Normal mode. | |
| 1154 | 661 It is not triggered when waiting for a command |
| 662 argument to be typed, or a movement after an | |
| 663 operator. | |

| 667 Internally the autocommand is triggered by the | |
| 668 <CursorHold> key. In an expression mapping | |
| 669 |getchar()| may see this character. | |
| 670 | |
| 579 | 671 Note: Interactive commands cannot be used for |
| 672 this event. There is no hit-enter prompt, | |
| 673 the screen is updated directly (when needed). | |
| 674 Note: In the future there will probably be | |
| 675 another option to set the time. | |
| 676 Hint: to force an update of the status lines | |
| 677 use: > | |

| 687 *CursorMoved* | |
| 4911 | 688 CursorMoved After the cursor was moved in Normal or Visual |
| 689 mode. Also when the text of the cursor line | |
| 690 has been changed, e.g., with "x", "rx" or "p". | |
| 25402 | 691 Not triggered when there is typeahead, while |
| 692 executing commands in a script file, when | |
| 25161 | 693 an operator is pending or when moving to |
| 694 another window while remaining at the same | |
| 695 cursor position. | |
| 667 | 696 For an example see |match-parens|. |
| 16023 | 697 Note: This can not be skipped with |
| 698 `:noautocmd`. | |
| 4264 | 699 Careful: This is triggered very often, don't |
| 700 do anything that the user does not expect or | |
| 701 that is slow. | |
| 661 | 702 *CursorMovedI* |
| 703 CursorMovedI After the cursor was moved in Insert mode. | |
| 3082 | 704 Not triggered when the popup menu is visible. |

| 708 changed. Useful to set up fonts, for example. | |
| 7 | 709 *FileAppendCmd* |
| 710 FileAppendCmd Before appending to a file. Should do the | |
| 26 | 711 appending to the file. Use the '[ and '] |
| 25973 | 712 marks for the range of lines. |Cmd-event| |
| 579 | 713 *FileAppendPost* |
| 714 FileAppendPost After appending to a file. | |
| 715 *FileAppendPre* | |

| 717 marks for the range of lines. | |
| 718 *FileChangedRO* | |
| 719 FileChangedRO Before making the first change to a read-only | |
| 720 file. Can be used to check-out the file from | |
| 721 a source control system. Not triggered when | |
| 722 the change was caused by an autocommand. | |
| 723 This event is triggered when making the first | |
| 724 change in a buffer or the first change after | |
| 823 | 725 'readonly' was set, just before the change is |
| 726 applied to the text. | |
| 579 | 727 WARNING: If the autocommand moves the cursor |
| 728 the effect of the change is undefined. | |
| 819 | 729 *E788* |
| 730 It is not allowed to change to another buffer | |
| 731 here. You can reload the buffer but not edit | |
| 732 another one. | |

| 757 cancelled if there is a modified buffer that | |
| 758 isn't automatically saved, use |VimLeavePre| | |
| 759 for really exiting. | |
| 7 | 760 *FileChangedShell* |
| 761 FileChangedShell When Vim notices that the modification time of | |
| 762 a file has changed since editing started. | |
| 763 Also when the file attributes of the file | |
| 5908 | 764 change or when the size of the file changes. |
| 765 |timestamp| | |
| 7 | 766 Mostly triggered after executing a shell |
| 767 command, but also with a |:checktime| command | |
| 11473 | 768 or when gvim regains input focus. |
| 7 | 769 This autocommand is triggered for each changed |
| 770 file. It is not used when 'autoread' is set | |
| 771 and the buffer was not changed. If a | |
| 772 FileChangedShell autocommand is present the | |
| 773 warning message and prompt is not given. | |
| 179 | 774 The |v:fcs_reason| variable is set to indicate |
| 775 what happened and |v:fcs_choice| can be used | |
| 776 to tell Vim what to do next. | |
| 7 | 777 NOTE: When this autocommand is executed, the |
| 778 current buffer "%" may be different from the | |
| 11347 | 779 buffer that was changed, which is in "<afile>". |
| 7 | 780 NOTE: The commands must not change the current |
| 781 buffer, jump to another buffer or delete a | |

782 buffer. *E246* *E811* |
| 7 | 783 NOTE: This event never nests, to avoid an |
| 784 endless loop. This means that while executing | |
| 785 commands for the FileChangedShell event no | |
| 786 other FileChangedShell event will be | |
| 787 triggered. | |
| 766 | 788 *FileChangedShellPost* |
| 789 FileChangedShellPost After handling a file that was changed outside | |
| 790 of Vim. Can be used to update the statusline. | |
| 579 | 791 *FileEncoding* |
| 792 FileEncoding Obsolete. It still works and is equivalent | |
| 793 to |EncodingChanged|. | |
| 794 *FileReadCmd* | |
| 795 FileReadCmd Before reading a file with a ":read" command. | |
| 796 Should do the reading of the file. |Cmd-event| | |
| 797 *FileReadPost* | |
| 798 FileReadPost After reading a file with a ":read" command. | |
| 799 Note that Vim sets the '[ and '] marks to the | |
| 800 first and last line of the read. This can be | |
| 801 used to operate on the lines just read. | |
| 802 *FileReadPre* | |
| 803 FileReadPre Before reading a file with a ":read" command. | |
| 804 *FileType* | |
| 1154 | 805 FileType When the 'filetype' option has been set. The |
| 806 pattern is matched against the filetype. | |
| 579 | 807 <afile> can be used for the name of the file |

| 579 | 811 See |filetypes|. |
| 812 *FileWriteCmd* | |
| 813 FileWriteCmd Before writing to a file, when not writing the | |
| 814 whole buffer. Should do the writing to the | |
| 815 file. Should not change the buffer. Use the | |
| 816 '[ and '] marks for the range of lines. | |
| 817 |Cmd-event| | |
| 818 *FileWritePost* | |
| 819 FileWritePost After writing to a file, when not writing the | |

| 822 FileWritePre Before writing to a file, when not writing the | |
| 823 whole buffer. Use the '[ and '] marks for the | |
| 824 range of lines. | |
| 825 *FilterReadPost* | |
| 826 FilterReadPost After reading a file from a filter command. | |
| 827 Vim checks the pattern against the name of | |
| 828 the current buffer as with FilterReadPre. | |
| 829 Not triggered when 'shelltemp' is off. | |
| 830 *FilterReadPre* *E135* | |
| 831 FilterReadPre Before reading a file from a filter command. | |
| 832 Vim checks the pattern against the name of | |
| 833 the current buffer, not the name of the | |
| 834 temporary file that is the output of the | |
| 835 filter command. | |
| 836 Not triggered when 'shelltemp' is off. | |
| 837 *FilterWritePost* | |
| 838 FilterWritePost After writing a file for a filter command or | |
| 15334 | 839 making a diff with an external diff (see |
| 25973 | 840 |DiffUpdated| for internal diff). |
| 579 | 841 Vim checks the pattern against the name of |
| 842 the current buffer as with FilterWritePre. | |
| 843 Not triggered when 'shelltemp' is off. | |
| 844 *FilterWritePre* | |
| 845 FilterWritePre Before writing a file for a filter command or | |
| 15334 | 846 making a diff with an external diff. |
| 579 | 847 Vim checks the pattern against the name of |
| 848 the current buffer, not the name of the | |
| 849 temporary file that is the output of the | |
| 850 filter command. | |
| 851 Not triggered when 'shelltemp' is off. | |
| 7 | 852 *FocusGained* |
| 853 FocusGained When Vim got input focus. Only for the GUI | |
| 854 version and a few console versions where this | |
| 855 can be detected. | |
| 856 *FocusLost* | |
| 857 FocusLost When Vim lost input focus. Only for the GUI | |
| 858 version and a few console versions where this | |
| 11 | 859 can be detected. May also happen when a |
| 860 dialog pops up. | |
| 7 | 861 *FuncUndefined* |
| 862 FuncUndefined When a user function is used but it isn't | |
| 863 defined. Useful for defining a function only | |
| 1154 | 864 when it's used. The pattern is matched |
| 865 against the function name. Both <amatch> and | |
| 866 <afile> are set to the name of the function. | |
| 23305 | 867 Not triggered when compiling a |Vim9| |
| 868 function. | |
| 6154 | 869 NOTE: When writing Vim scripts a better |
| 870 alternative is to use an autoloaded function. | |
| 161 | 871 See |autoload-functions|. |
| 579 | 872 *GUIEnter* |
| 873 GUIEnter After starting the GUI successfully, and after | |
| 874 opening the window. It is triggered before | |
| 875 VimEnter when using gvim. Can be used to | |
| 876 position the window from a .gvimrc file: > | |
| 877 :autocmd GUIEnter * winpos 100 50 | |
| 1154 | 878 < *GUIFailed* |
| 879 GUIFailed After starting the GUI failed. Vim may | |
| 880 continue to run in the terminal, if possible | |
| 881 (only on Unix and alikes, when connecting the | |
| 882 X server fails). You may want to quit Vim: > | |
| 883 :autocmd GUIFailed * qall | |
| 579 | 884 < *InsertChange* |
| 885 InsertChange When typing <Insert> while in Insert or | |
| 886 Replace mode. The |v:insertmode| variable | |
| 887 indicates the new mode. | |
| 888 Be careful not to move the cursor or do | |
| 889 anything else that the user does not expect. | |
| 2845 | 890 *InsertCharPre* |
| 891 InsertCharPre When a character is typed in Insert mode, | |
| 892 before inserting the char. | |
| 893 The |v:char| variable indicates the char typed | |
| 894 and can be changed during the event to insert | |
| 895 a different character. When |v:char| is set | |
| 896 to more than one character this text is | |
| 897 inserted literally. | |
| 898 It is not allowed to change the text |textlock|. | |
| 899 The event is not triggered when 'paste' is | |
| 13437 | 900 set. {only with the +eval feature} |
| 579 | 901 *InsertEnter* |
| 1154 | 902 InsertEnter Just before starting Insert mode. Also for |
| 903 Replace mode and Virtual Replace mode. The | |
| 579 | 904 |v:insertmode| variable indicates the mode. |
| 4448 | 905 Be careful not to do anything else that the |
| 906 user does not expect. | |
| 907 The cursor is restored afterwards. If you do | |
| 908 not want that set |v:char| to a non-empty | |
| 909 string. | |

| 1061 | 1081 *SourceCmd* |
| 1082 SourceCmd When sourcing a Vim script. |:source| | |
| 1083 <afile> is the name of the file being sourced. | |
| 1084 The autocommand must source this file. | |
| 1085 |Cmd-event| | |
| 650 | 1086 *SpellFileMissing* |
| 1087 SpellFileMissing When trying to load a spell checking file and | |
| 1061 | 1088 it can't be found. The pattern is matched |
| 1089 against the language. <amatch> is the | |
| 1090 language, 'encoding' also matters. See | |
| 650 | 1091 |spell-SpellFileMissing|. |
| 579 | 1092 *StdinReadPost* |
| 1093 StdinReadPost After reading from the stdin into the buffer, | |
| 1094 before executing the modelines. Only used | |
| 1095 when the "-" argument was used when Vim was | |
| 1096 started |--|. | |
| 1097 *StdinReadPre* | |
| 1098 StdinReadPre Before reading from stdin into the buffer. | |
| 1099 Only used when the "-" argument was used when | |
| 1100 Vim was started |--|. | |
| 1101 *SwapExists* | |
| 1102 SwapExists Detected an existing swap file when starting | |
| 1103 to edit a file. Only when it is possible to | |
| 1104 select a way to handle the situation, when Vim | |
| 1105 would ask the user what to do. | |
| 1106 The |v:swapname| variable holds the name of | |
| 590 | 1107 the swap file found, <afile> the file being |
| 1108 edited. |v:swapcommand| may contain a command | |
| 1109 to be executed in the opened file. | |
| 1110 The commands should set the |v:swapchoice| | |
| 1111 variable to a string with one character to | |
| 1112 tell Vim what should be done next: | |
| 579 | 1113 'o' open read-only |
| 1114 'e' edit the file anyway | |
| 1115 'r' recover | |
| 1116 'd' delete the swap file | |
| 1117 'q' quit, don't edit the file | |
| 1118 'a' abort, like hitting CTRL-C | |
| 1119 When set to an empty string the user will be | |
| 1120 asked, as if there was no SwapExists autocmd. | |
| 1919 | 1121 *E812* |
| 1122 It is not allowed to change to another buffer, | |
| 1123 change a buffer name or change directory | |
| 1124 here. | |
| 13437 | 1125 {only available with the +eval feature} |
| 579 | 1126 *Syntax* |
| 1154 | 1127 Syntax When the 'syntax' option has been set. The |
| 1128 pattern is matched against the syntax name. | |
| 579 | 1129 <afile> can be used for the name of the file |
| 1130 where this option was set, and <amatch> for | |
| 1131 the new value of 'syntax'. | |
| 1132 See |:syn-on|. | |

| 1314 6. Patterns *autocmd-patterns* *{pat}* | |
| 1315 | |
| 6741 | 1316 The {pat} argument can be a comma separated list. This works as if the |
| 1317 command was given with each pattern separately. Thus this command: > | |
| 1318 :autocmd BufRead *.txt,*.info set et | |
| 1319 Is equivalent to: > | |
| 1320 :autocmd BufRead *.txt set et | |
| 1321 :autocmd BufRead *.info set et | |
| 1322 | |
| 7 | 1323 The file pattern {pat} is tested for a match against the file name in one of |
| 1324 two ways: | |
| 1325 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1326 the tail part of the file name (without its leading directory path). | |

1329 it to a full path and resolving symbolic links). |
| 7 | 1330 |
| 40 | 1331 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1332 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1333 of a buffer. | |
| 1334 | |
| 7 | 1335 Examples: > |
| 1336 :autocmd BufRead *.txt set et | |
| 1337 Set the 'et' option for all text files. > | |
| 1338 | |
| 1339 :autocmd BufRead /vim/src/*.c set cindent | |
| 1340 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1341 | |
| 1342 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1343 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1344 you start editing "/tmp/test.c", this autocommand will match. | |
| 1345 | |
| 1346 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1347 the first character. Example: > | |
| 1348 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1349 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1350 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1351 | |
| 1352 | |
| 1353 The file name that the pattern is matched against is after expanding | |
| 1621 | 1354 wildcards. Thus if you issue this command: > |
| 7 | 1355 :e $ROOTDIR/main.$EXT |
| 1356 The argument is first expanded to: > | |
| 1357 /usr/root/main.py | |
| 1358 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1359 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1360 expect. | |
| 1361 | |
| 1362 | |
| 1363 Environment variables can be used in a pattern: > | |
| 1364 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1365 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1366 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1367 :autocmd BufRead ~archive/* set readonly | |
| 1368 The environment variable is expanded when the autocommand is defined, not when | |
| 1369 the autocommand is executed. This is different from the command! | |
| 1370 | |
| 1371 *file-pattern* | |
| 1372 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1373 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1374 separators |
| 7 | 1375 ? matches any single character |
| 1376 \? matches a '?' | |
| 1377 . matches a '.' | |
| 1378 ~ matches a '~' | |
| 1379 , separates patterns | |
| 1380 \, matches a ',' | |
| 1381 { } like \( \) in a |pattern| | |
| 1382 , inside { }: like \| in a |pattern| | |

| 40 | 1397 *autocmd-changes* |
| 7 | 1398 Matching with the pattern is done when an event is triggered. Changing the |
| 1399 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1400 change which autocommands will be executed. Example: > | |
| 1401 | |
| 1402 au BufEnter *.foo bdel | |
| 1403 au BufEnter *.foo set modified | |
| 1404 | |
| 1405 This will delete the current buffer and then set 'modified' in what has become | |
| 1406 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1407 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1408 buffer at the moment the event was triggered. | |
| 1409 | |
| 40 | 1410 However, buffer-local autocommands will not be executed for a buffer that has |
| 1411 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1412 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1413 still executed. | |
| 1414 | |
| 7 | 1415 ============================================================================== |
| 856 | 1416 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1417 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1418 |
| 1419 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1420 if the buffer does not have a name and when the name does not match a specific | |
| 1421 pattern. But it also means they must be explicitly added to each buffer. | |
| 1422 | |
| 1423 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1424 <buffer> current buffer | |
| 1425 <buffer=99> buffer number 99 | |
| 1426 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1427 |<abuf>| | |
| 1428 | |
| 1429 Examples: > | |
| 1430 :au CursorHold <buffer> echo 'hold' | |
| 1431 :au CursorHold <buffer=33> echo 'hold' | |

|
1432 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1433 |
| 1434 All the commands for autocommands also work with buffer-local autocommands, | |
| 1435 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1436 :au! * <buffer> " remove buffer-local autocommands for |
| 1437 " current buffer | |
| 1438 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1439 " buffer #33 | |
| 1621 | 1440 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1441 " buffers |
| 1442 :au * <buffer> " list buffer-local autocommands for | |
| 1443 " current buffer | |
| 40 | 1444 |
| 1445 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1446 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1447 number of the current buffer. You will see this when listing autocommands, | |
| 1448 for example. | |
| 1449 | |
| 1450 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1451 as follows: > | |
| 1452 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1453 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1454 | |
| 1455 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1456 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1457 unlisted, the autocommands are still present. In order to see the removal of | |
| 1458 buffer-local autocommands: > | |
| 1459 :set verbose=6 | |
| 1460 | |
| 1461 It is not possible to define buffer-local autocommands for a non-existent | |
| 1462 buffer. | |
| 1463 | |
| 1464 ============================================================================== | |
| 1465 8. Groups *autocmd-groups* | |
| 7 | 1466 |
| 1467 Autocommands can be put together in a group. This is useful for removing or | |
| 1468 executing a group of autocommands. For example, all the autocommands for | |
| 1469 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1470 ":doautoall highlight BufRead" when the GUI starts. | |
| 1471 | |
| 1472 When no specific group is selected, Vim uses the default group. The default | |
| 1473 group does not have a name. You cannot execute the autocommands from the | |
| 1474 default group separately; you can execute them only by executing autocommands | |
| 1475 for all groups. | |
| 1476 | |
| 1477 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1478 for all groups. The group only matters when executing autocommands with | |
| 1479 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1480 | |
| 1481 The group name can contain any characters except white space. The group name | |
| 1482 "end" is reserved (also in uppercase). | |

1498 this group! You will get a warning if doing |
| 21676 | 1499 it anyway. When the group is the current |
| 1500 group you will get error E936. | |
| 7 | 1501 |
| 1502 To enter autocommands for a specific group, use this method: | |
| 1503 1. Select the group with ":augroup {name}". | |
| 1504 2. Delete any old autocommands with ":au!". | |
| 1505 3. Define the autocommands. | |
| 1506 4. Go back to the default group with "augroup END". | |
| 1507 | |
| 1508 Example: > | |
| 1509 :augroup uncompress | |
| 1510 : au! | |
| 1511 : au BufEnter *.gz %!gunzip | |
| 1512 :augroup END | |
| 1513 | |
| 1514 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1515 .vimrc file again). | |
| 1516 | |
| 25880 | 1517 *FileExplorer* |
| 1518 There is one group that is recognized by Vim: FileExplorer. If this group | |
| 1519 exists Vim assumes that editing a directory is possible and will trigger a | |
| 1520 plugin that lists the files in that directory. This is used by the |netrw| | |
| 1521 plugin. This allows you to do: > | |
| 1522 browse edit | |
| 1523 | |
| 7 | 1524 ============================================================================== |
| 40 | 1525 9. Executing autocommands *autocmd-execute* |
| 7 | 1526 |
| 1527 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1528 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1529 (e.g., the file pattern match was wrong). | |
| 1530 | |
| 1531 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1532 option will not cause any commands to be executed. | |
| 1533 | |
| 16944 | 1534 *:do* *:doau* *:doaut* *:doautocmd* *E217* |
| 3356 | 1535 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1536 Apply the autocommands matching [fname] (default: |
| 1537 current file name) for {event} to the current buffer. | |
| 1538 You can use this when the current file name does not | |
| 1539 match the right pattern, after changing settings, or | |
| 1540 to execute autocommands for a certain event. | |
| 1541 It's possible to use this inside an autocommand too, | |
| 1542 so you can base the autocommands for one extension on | |
| 1543 another extension. Example: > | |
| 3224 | 1544 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1545 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1546 < Be careful to avoid endless loops. See |
| 1547 |autocmd-nested|. | |
| 1548 | |
| 1549 When the [group] argument is not given, Vim executes | |
| 1550 the autocommands for all groups. When the [group] | |
| 1551 argument is included, Vim executes only the matching | |
| 1552 autocommands for that group. Note: if you use an | |
| 1553 undefined group name, Vim gives you an error message. | |
| 3350 | 1554 *<nomodeline>* |
| 1555 After applying the autocommands the modelines are | |
| 1556 processed, so that their settings overrule the | |
| 1557 settings from autocommands, like what happens when | |
| 1558 editing a file. This is skipped when the <nomodeline> | |
| 1559 argument is present. You probably want to use | |
| 1560 <nomodeline> for events that are not used when loading | |
| 1561 a buffer, such as |User|. | |

1563 matching autocommands were executed. |
| 7 | 1564 |
| 1565 *:doautoa* *:doautoall* | |
| 3342 | 1566 :doautoa[ll] [<nomodeline>] [group] {event} [fname] |
| 7 | 1567 Like ":doautocmd", but apply the autocommands to each |
| 24278 | 1568 loaded buffer. The current buffer is done last. |
| 1569 | |
| 1570 Note that [fname] is used to select the autocommands, | |
| 24569 | 1571 not the buffers to which they are applied. Example: > |
| 1572 augroup mine | |
| 1573 autocmd! | |
| 1574 autocmd FileType * echo expand('<amatch>') | |
| 1575 augroup END | |
| 1576 doautoall mine FileType Loaded-Buffer | |
| 1577 < Sourcing this script, you'll see as many | |
| 1578 "Loaded-Buffer" echoed as there are loaded buffers. | |
| 24278 | 1579 |
| 7 | 1580 Careful: Don't use this for autocommands that delete a |
| 1581 buffer, change to another buffer or change the | |
| 1582 contents of a buffer; the result is unpredictable. | |
| 1583 This command is intended for autocommands that set | |
| 1584 options, change highlighting, and things like that. | |
| 1585 | |
| 1586 ============================================================================== | |
| 40 | 1587 10. Using autocommands *autocmd-use* |
| 7 | 1588 |
| 1589 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1590 of these sets for a write command: | |
| 1591 | |
| 1592 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1593 FilterWritePre FilterWritePost writing to filter temp file | |
| 1594 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1595 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1596 | |
| 1597 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1598 writing. No further writing is done and the other events are not triggered. | |
| 1599 |Cmd-event| | |
| 1600 | |
| 1601 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1602 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1603 the side effect of changing the buffer. | |
| 1604 | |
| 1605 Before executing the autocommands, the buffer from which the lines are to be | |
| 1606 written temporarily becomes the current buffer. Unless the autocommands | |
| 1607 change the current buffer or delete the previously current buffer, the | |
| 1608 previously current buffer is made the current buffer again. | |
| 1609 | |
| 1610 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1611 which the lines are to be written. | |
| 1612 | |
| 1613 The '[ and '] marks have a special position: | |
| 1614 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1615 the new lines will be inserted. | |
| 1616 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1617 just read, the '] mark to the last line. | |
| 26 | 1618 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1619 mark is set to the first line that will be written, the '] mark to the last | |
| 1620 line. | |
| 7 | 1621 Careful: '[ and '] change when using commands that change the buffer. |
| 1622 | |
| 1623 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1624 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1625 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1626 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1627 work for files without a buffer (e.g., with ":r file"). |
| 1628 | |
| 1629 *gzip-example* | |
| 1630 Examples for reading and writing compressed files: > | |
| 1631 :augroup gzip | |
| 1632 : autocmd! | |
| 1633 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1634 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1635 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 1636 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
| 1637 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
| 1638 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1639 | |
| 1640 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1641 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1642 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1643 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1644 :augroup END | |
| 1645 | |
| 1646 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1647 ":autocmd!", for when the file is sourced twice. | |
| 1648 | |
| 1649 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1650 | |
| 1651 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1652 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1653 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1654 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1655 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1656 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1657 'modified' option. | |
| 1658 | |
| 1659 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1660 command. Use with care! If the Normal mode command is not finished, the user | |
| 1661 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1662 name). | |
| 1663 | |
| 1664 If you want the buffer to be unmodified after changing it, reset the | |
| 1665 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1666 instead of ":q!". | |
| 1667 | |
| 1668 *autocmd-nested* *E218* | |
| 16023 | 1669 By default, autocommands do not nest. For example, if you use ":e" or ":w" in |
| 1670 an autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 7 | 1671 those commands. If you do want this, use the "nested" flag for those commands |
| 1672 in which you want nesting. For example: > | |

|
1673 :autocmd FileChangedShell *.c ++nested e! |
| 7 | 1674 The nesting is limited to 10 levels to get out of recursive loops. |
| 1675 | |
| 1676 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1677 self-modifying command! This can be useful for an autocommand that should | |
| 1678 execute only once. | |
| 1679 | |
| 590 | 1680 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1681 modifier or the 'eventignore' option. | |
| 7 | 1682 |
| 1683 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1684 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1685 write (with ":write file" or with a filter command), if the same line is | |
| 1686 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1687 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1688 same file as was read, and makes a write command on just filtered lines write | |
| 1689 the same file as was read from the filter. For example, another way to write | |
| 1690 a compressed file: > | |
| 1691 | |
| 1692 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1693 :autocmd FileWritePost *.gz undo|set nobin | |
| 1694 < | |
| 1695 *autocommand-pattern* | |
| 1696 You can specify multiple patterns, separated by commas. Here are some | |
| 1697 examples: > | |
| 1698 | |
| 1699 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
| 1700 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
| 1701 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
| 1702 :autocmd BufLeave .letter set dict= | |
| 1703 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
| 1704 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
| 1705 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1706 | |
| 1707 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1708 | |
| 1709 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1710 :autocmd BufLeave ?akefile* set include& | |
| 1711 | |
| 1712 To always start editing C files at the first function: > | |
| 1713 | |
| 1714 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1715 | |
| 1716 Without the "1;" above, the search would start from wherever the file was | |
| 1717 entered, rather than from the start of the file. | |
| 1718 | |
| 1719 *skeleton* *template* | |
| 1720 To read a skeleton (template) file when opening a new file: > | |
| 1721 | |
| 1722 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
| 1723 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
| 1724 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
| 1725 | |
| 1726 To insert the current date and time in a *.html file when writing it: > | |
| 1727 | |
| 1728 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1729 :fun LastMod() | |
| 1730 : if line("$") > 20 | |
| 1731 : let l = 20 | |
| 1732 : else | |
| 1733 : let l = line("$") | |
| 1734 : endif | |
| 1735 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
| 1736 : \ strftime("%Y %b %d") | |
| 1737 :endfun | |
| 1738 | |
| 1739 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1740 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1741 same line after it) with the current date and time. Explanation: | |
| 1742 ks mark current position with mark 's' | |
| 1743 call LastMod() call the LastMod() function to do the work | |
| 1744 's return the cursor to the old position | |
| 1745 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1746 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1747 lines the ":s" command is executed to replace the existing date with the | |
| 1748 current one. The ":execute" command is used to be able to use an expression | |
| 1749 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1750 function. You can change its argument to get another date string. | |
| 1751 | |
| 1752 When entering :autocmd on the command-line, completion of events and command | |
| 1753 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1754 | |
| 1755 Vim executes all matching autocommands in the order that you specify them. | |
| 1756 It is recommended that your first autocommand be used for all files by using | |
| 1757 "*" as the file pattern. This means that you can define defaults you like | |
| 1758 here for any settings, and if there is another matching autocommand it will | |
| 1759 override these. But if there is no other matching autocommand, then at least | |
| 1760 your default settings are recovered (if entering this file from another for | |
| 1761 which autocommands did match). Note that "*" will also match files starting | |
| 1762 with ".", unlike Unix shells. | |
| 1763 | |
| 1764 *autocmd-searchpat* | |
| 1765 Autocommands do not change the current search patterns. Vim saves the current | |
| 1766 search patterns before executing autocommands then restores them after the | |
| 1767 autocommands finish. This means that autocommands do not affect the strings | |
| 1768 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1769 use search patterns normally, e.g., with the "n" command. | |
| 1770 If you want an autocommand to set the search pattern, such that it is used | |
| 1771 after the autocommand finishes, use the ":let @/ =" command. | |
| 1772 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1773 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1774 highlighting when starting Vim. | |
| 1775 | |
| 1776 *Cmd-event* | |
| 1777 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1778 do the file reading, writing or sourcing. This can be used when working with |
| 1779 a special kind of file, for example on a remote system. | |
| 7 | 1780 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1781 making it impossible to read or write the matching files! Make sure you test | |
| 1782 your autocommands properly. Best is to use a pattern that will never match a | |
| 1783 normal file name, for example "ftp://*". | |
| 1784 | |
| 1785 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1786 editing session. When recovering from the original file, Vim reads only those | |
| 1787 parts of a file that are not found in the swap file. Since that is not | |
| 1788 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1789 original file isn't needed for recovery. You might want to do this only when | |
| 1790 you expect the file to be modified. | |
| 1791 | |
| 1061 | 1792 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1793 and "++ff=" argument that are effective. These should be used for the command | |
| 1794 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1795 used, zero otherwise. | |

| 1800 11. Disabling autocommands *autocmd-disable* | |
| 1801 | |
| 1802 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1803 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1804 afterwards, using a |:try| block with |:finally|. | |
| 1805 | |
| 1806 *:noautocmd* *:noa* | |
| 1807 To disable autocommands for just one command use the ":noautocmd" command | |
| 1808 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1809 following command. Example: > | |
| 1810 | |
| 1811 :noautocmd w fname.gz | |
| 1812 | |
| 1813 This will write the file without triggering the autocommands defined by the | |
| 1814 gzip plugin. | |
| 1815 | |
| 16023 | 1816 Note that some autocommands are not triggered right away, but only later. |
| 1817 This specifically applies to |CursorMoved| and |TextChanged|. | |
