" Vim indent file
|
|
" Language: PHP
|
|
" Author: Miles Lott <milos@groupwhere.org>
|
|
" URL: http://milosch.dyndns.org/php.vim
|
|
" Last Change: 2004 May 18
|
|
" Version: 0.5
|
|
" Notes: Close all switches with default:\nbreak; and it will look better.
|
|
" Also, open and close brackets should be alone on a line.
|
|
" This is my preference, and the only way this will look nice.
|
|
" Try an older version if you care less about the formatting of
|
|
" switch/case. It is nearly perfect for anyone regardless of your
|
|
" stance on brackets.
|
|
"
|
|
" Changes: 0.5 - fix duplicate indent on open tag, and empty bracketed
|
|
" statements.
|
|
" 0.4 - Fixes for closing php tag, switch statement closure, and php_indent_shortopentags
|
|
" option from Steffen Bruentjen <vim@kontraphon.de>
|
|
"
|
|
" Options: php_noindent_switch=1 -- do not try to indent switch/case statements (version 0.1 behavior)
|
|
" php_indent_shortopentags=1 -- indent after short php open tags, too
|
|
|
|
" Only load this indent file when no other was loaded.
