Vim latex 自动补全
一般情况下，小的文档都是用 texworks 编辑的。但是 texworks 不如 vim 的操作方便，所以今天配置了一下。需要先安装 vim-plug ：
然后安装 ultisnips 和vim-snippets：
" vim-plug
call plug#begin('~/.vim/plugged')
Plug 'SirVer/ultisnips'
Plug 'honza/vim-snippets'
call plug#end()"
接着配置 ultisnips：
mkdir ~/.vim/UltiSnips
cd ~/.vim/UltiSnips
cd .>tex.snippets
现在打开用vim打开 tex.snippets
:e ~/.vim/tex.snippets
定义一个文档snippet：
snippet doca "article" b
\documentclass[11pt]{article}
\usepackage{fontspec, xunicode, xltxtra}
\usepackage[tmargin=1in,bmargin=1in,lmargin=1.25in,rmargin=1.25in]{geometry} \setmainfont{STSongti-TC-Bold}[ BoldFont = ToppanBunkyuMidashiMinchoStdN-ExtraBold, ItalicFont = HYShangWeiShouShuW-Regular, %BoldItalicFont = texgyrepagella-bolditalic.otf ] \usepackage{etoolbox}} \begin{document} ${0} \end{document} endsnippet $0 代表鼠标所在的位置
b 代表
UltiSnips 会自动抓取最新的修改，所以我们不用重启 vim，只要保存了 snippet 文件，就可以直接使用。简单来说，定义的一段 snip 的格式是这样的：
- snippet 关键词 “说明” 设定
- 内容
- endsnippet
在刚才那段 snip 里，std 就是我们可以展开的 关键词，"use namespace std"是一段说明（如果你用一些自动补全的插件，这段说明就会显示出来，我们之后自然会提到，放心），而 b 的是关于这个 snip 的设定，
- b 代表只有关键词出现在行首的时候，才可以被展开
- A 代表自动展开
- w 代表可以展开这个 “词”，具体 “词” 的定义可以查看
:help iskeyword。直观感觉就是，这个关键词是单独的，和其他文字分开的。比如前后都是空格。 - i 代表可以忽略前后字节，直接展开关键词。（这个设定比 w 要更松）
其他的还有r, s, t, m等等，都可以通过这个命令在自带文档里找到:
:help ultisnip

代码如下：
snippet class "class" b
class ${1:Class}{
public:
// constructors, asssignment, destructor
$1();
$1(const $1&); $1& operator=(const $1&); ~$1(); private: }; endsnippet 这是我的基本配置：
snippet doca "article" b
