VIM+LaTeX 自动补全

先看看效果如何：

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 ：

• https://github.com/junegunn/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
\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
   


snippet docb "book" b
\documentclass[11pt]{book}
\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
]
