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
|
