VIM配置

Linux下的编辑器以vim和emacs为主流，一个编辑器之神，一个是神的编辑器。

本文以主要介绍如何在linux下以vim为基础搭建一个比较顺手的代码编辑器。

• 有两种比较流行的方式：

自动安装
手动安装

• 自动安装

　　这种是方法是比较省事的方法，只要一个.vimrc配置文件就可以搞定所有的事情，一次配好即可。以后只要有这个配置文件，就可以走遍天下。
这种方式需要使用一个VIM插件管理工具来自动管理VIM插件的安装与卸载，笔者使用的Vundle来管理VIM插件，Vundle的全称是Vim Bundle，它是一款Vim插件管理工具。Vundle让你可以非常轻松地安装、更新、搜索和清理Vim插件。它还能管理你的运行时环境，并帮助标记。

• • 可以在Github上下载Vundle： https://github.com/VundleVim/Vundle.vim

下载完成后，解压到用户根目录的.vim目录下即可

• • 在终端（命令行）中使用git clone获取： git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

clone完成后， 会在用户根目录下多出来一个bundle目录，此时Vundle已经安装完成。安装好Vundle以后，就可以根据自己的需要安装插件了。Vundle提供了几种不同的插件安装方式，一般我们用到的插件在github都可以找到，因此最常用的一般就是直接找github上插件对应的仓名，添加到.vimrc中即可。然后打开vim，执行:PluginInstall命令，即可自动安装，等待Vundle执行完下载安装操作后，就可以开始享受VIM了。

笔者的.vimrc文件配置如下：

"===============================================================================================
set nocompatible " be iMproved, required
filetype off " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'

" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'

" plugin from http://vim-scripts.org/vim/scripts.html
Plugin 'L9'

" Git plugin not hosted on GitHub
"Plugin 'git://git.wincent.com/command-t.git'

" git repos on your local machine (i.e. when working on your own plugin)
"Plugin 'file:///home/gmarik/path/to/plugin'

" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
"Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}

" Install L9 and avoid a Naming conflict if you've already installed a
" different version somewhere else.
"Plugin 'ascenator/L9', {'name': 'newL9'}

" All of your Plugins must be added before the following line

• 手动安装

手动安装，当然是要自己一个一个地安装插件了。这种方式的特点是需要自己一个一下下载vim插件，然后手动进行安装。虽然比较费事，但如果之前有vim插件安装包的备份文件，那就可以不依赖于网络。所以还是推荐在自己的本地留一份常用插件的安装包备份。手动安装的过程比较简单，基本上就是“下载-解压”，先从网卡下载好插件的压缩包，一般来说直接解压到.vim目录中即可。

笔者常用的几个插件如下，一般都可以在github上找到，其实从上面的配置文件中就可以找到笔者使用了哪些vim插件。
Plugin 'scrooloose/nerdtree'
Plugin 'kien/ctrlp.vim'
Plugin 'vim-airline/vim-airline'
Plugin 'vim-airline/vim-airline-themes'
Plugin 'majutsushi/tagbar'
Plugin 'tacahiroy/ctrlp-funky'
Plugin 'jlanzarotta/bufexplorer'
Plugin 'easymotion/vim-easymotion'
Plugin 'haya14busa/incsearch.vim'
Plugin 'dkprice/vim-easygrep'
Plugin 'dyng/ctrlsf.vim'
Plugin 'Xuyuanp/nerdtree-git-plugin'
Plugin 'hfts/Porsche'
Plugin 'vim-scripts/OmniCppComplete'
Plugin 'vim-scripts/AutoComplPop'
Plugin 'scrooloose/nerdcommenter'

最后，附上笔者vim的两张截图：
