" This script does more useful indenting for Mako HTML templates. It indents
|
|
|
|
|
" inside of control blocks, defs, etc. Note that this indenting style will
|
|
|
|
|
" sacrifice readability of the output text for the sake of readability of the
|
|
|
|
|
" template.
|
|
|
|
|
"
|
|
|
|
|
" We'll use HTML indenting globally, python inside <% %> blocks. Inspired by
|
|
|
|
|
" the excellent PHP + HTML indentation files such as php.vim by Pim Snel.
