先看看效果如何：
Vim latex 自動補全
一般情況下，小的文檔都是用 texworks 編輯的。但是 texworks 不如 vim 的操作方便，所以今天配置了一下。需要先安裝 vim-plug ：
然后安裝 ultisnips 和vim-snippets：
" vim-plug
call plug#begin('~/.vim/plugged')
Plug 'SirVer/ultisnips'
Plug 'honza/vim-snippets'
call plug#end()"
接著配置 ultisnips：
mkdir ~/.vim/UltiSnips
cd ~/.vim/UltiSnips
cd .>tex.snippets
現在打開用vim打開 tex.snippets
:e ~/.vim/tex.snippets
定義一個文檔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 代表鼠標所在的位置
b 代表
UltiSnips 會自動抓取最新的修改，所以我們不用重啟 vim，只要保存了 snippet 文件，就可以直接使用。簡單來說，定義的一段 snip 的格式是這樣的：
- snippet 關鍵詞 “說明” 設定
- 內容
- endsnippet
在剛才那段 snip 里，std 就是我們可以展開的 關鍵詞，"use namespace std"是一段說明（如果你用一些自動補全的插件，這段說明就會顯示出來，我們之后自然會提到，放心），而 b 的是關于這個 snip 的設定，
- b 代表只有關鍵詞出現在行首的時候，才可以被展開
- A 代表自動展開
-
w 代表可以展開這個 “詞”，具體 “詞” 的定義可以查看
:help iskeyword。直觀感覺就是，這個關鍵詞是單獨的，和其他文字分開的。比如前后都是空格。 -
i 代表可以忽略前后字節，直接展開關鍵詞。（這個設定比 w 要更松）
其他的還有r, s, t, m等等，都可以通過這個命令在自帶文檔里找到:
:help ultisnip

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