| 8457 * do_autocmd() -- implements the :autocmd command. Can be used in the | |
| 8458 * following ways: | |
| 8459 * | |
| 8460 * :autocmd <event> <pat> <cmd> Add <cmd> to the list of commands that | |
| 8461 * will be automatically executed for <event> | |
| 8462 * when editing a file matching <pat>, in | |
| 8463 * the current group. | |
| 8464 * :autocmd <event> <pat> Show the auto-commands associated with | |
| 8465 * <event> and <pat>. | |
| 8466 * :autocmd <event> Show the auto-commands associated with | |
| 8467 * <event>. | |
| 8468 * :autocmd Show all auto-commands. | |
| 8469 * :autocmd! <event> <pat> <cmd> Remove all auto-commands associated with | |
| 8470 * <event> and <pat>, and add the command | |
| 8471 * <cmd>, for the current group. | |
| 8472 * :autocmd! <event> <pat> Remove all auto-commands associated with | |
| 8473 * <event> and <pat> for the current group. | |
| 8474 * :autocmd! <event> Remove all auto-commands associated with | |
| 8475 * <event> for the current group. | |
| 8476 * :autocmd! Remove ALL auto-commands for the current | |
| 8477 * group. | |
| 8478 * | |
| 8479 * Multiple events and patterns may be given separated by commas. Here are | |
| 8480 * some examples: | |
| 8481 * :autocmd bufread,bufenter *.c,*.h set tw=0 smartindent noic | |
| 8482 * :autocmd bufleave * set tw=79 nosmartindent ic infercase | |
| 8483 * | |
| 8484 * :autocmd * *.c show all autocommands for *.c files. | |
| 609 | 8485 * |
| 8486 * Mostly a {group} argument can optionally appear before <event>. | |
