| 2 | " Language: PHP |
| 3 | " Author: Miles Lott <milos@groupwhere.org> |
| 4 | " URL: http://milosch.dyndns.org/php.vim |
| 5 | " Last Change: 2004 May 18 |
| 6 | " Version: 0.5 |
| 7 | " Notes: Close all switches with default:\nbreak; and it will look better. |
| 8 | " Also, open and close brackets should be alone on a line. |
| 9 | " This is my preference, and the only way this will look nice. |
| 10 | " Try an older version if you care less about the formatting of |
| 11 | " switch/case. It is nearly perfect for anyone regardless of your |
| 12 | " stance on brackets. |
| 13 | " |
| 14 | " Changes: 0.5 - fix duplicate indent on open tag, and empty bracketed |
| 15 | " statements. |
| 16 | " 0.4 - Fixes for closing php tag, switch statement closure, and php_indent_shortopentags |
| 17 | " option from Steffen Bruentjen <vim@kontraphon.de> |
| 18 | " |
| 19 | " Options: php_noindent_switch=1 -- do not try to indent switch/case statements (version 0.1 behavior) |
| 20 | " php_indent_shortopentags=1 -- indent after short php open tags, too |
| 21 | |
