" Version: 0.5
|

" Created: Sat, 16 Feb 2002 16:50:19 +0100

" Last Change: Mar, 27 Jun 2011 11:46:35 +0200
|

" Last Update: 18th feb 2002, by LH :
|
||||
" (*) better support for the option
|
||||
" (*) use some regex instead of several '||'.
|
||||
" Oct 9th, 2003, by JT:
|
||||
" (*) don't change indentation of lines starting with '%'
|
||||
" 2005/06/15, Moshe Kaminsky <kaminsky@math.huji.ac.il>
|
||||
" (*) New variables:
|
||||
" g:tex_items, g:tex_itemize_env, g:tex_noindent_env
|
||||
" 2011/3/6, by Zhou Yi Chao <broken.zhou@gmail.com>
|
||||
" (*) Don't change indentation of lines starting with '%'
|
||||
" I don't see any code with '%' and it doesn't work properly
|
||||
" so I add some code.
|
||||
" (*) New features: Add smartindent-like indent
|
||||
" for "{}" and "[]".
|
||||
" (*) New variables: g:tex_indent_brace
|
||||
"
|
||||
" Options: {{{
|
||||
"
|
||||
" To set the following options (ok, currently it's just one), add a line like
|
||||
" let g:tex_indent_items = 1
|
||||
" to your ~/.vimrc.
|
||||
"
|
||||
" * g:tex_indent_brace
|
||||
"
|
||||
" If this variable is unset or non-zero, it will use smartindent-like style
|
||||
" for "{}" and "[]"
|
||||
"
|
||||
" * g:tex_indent_items
|
||||
"
|
||||
" If this variable is set, item-environments are indented like Emacs does
|
||||
" it, i.e., continuation lines are indented with a shiftwidth.
|
||||
"
|
||||
" NOTE: I've already set the variable below; delete the corresponding line
|
||||
" if you don't like this behaviour.
|
||||
"
|
||||
" Per default, it is unset.
