我的vimrc配置

　　从上个暑假开始接触vim，一下子爱上了这个轻量的文本编辑器。目前我用vim主要是用来写python代码，下一步想要接触一下LaTex和Markdown。接触过vim的人都知道，vimrc是每个人的心血，每个爱折腾的人都有一个强大的vimrc。vim也正是因为插件和高度自定义化赢得越来越多的人的喜爱。下面把自己的vimrc记录在此，权当做个备份。

syntax on                  " Enable syntax highlighting.
filetype plugin indent on  " Enable file type based indentation.

set autoindent             " Respect indentation when starting a new line.
set expandtab              " Expand tabs to spaces. Essential in Python.
set tabstop=4              " Number of spaces tab is counted for.
set shiftwidth=4           " Number of spaces to use for autoindent.
set mouse=a               " 可以使用鼠标
set backspace=2            " Fix backspace behavior on most terminals.
