vim编辑器对python的扩展

vim是我最常用的编辑器，功能足够丰富，并且支持扩展，下面对vim加一个Vundle插件。Vundle对应vim，就像pip对于python一样，是可以装其他plugin的管理器。再通过Vundle安装YouCompleteMe engine

# cat /etc/centos-release
CentOS release 6.7 (Final)
# vim --version|head -n 1
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jul 24 2015 02:23:23)

安装Vundle，git克隆 Vundle，要不然其他插件就装不上了。设置.vimrc

git clone代码
[root@vm01 ~]# git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim
[root@vm01 ~]# cd ~/.vim/bundle/YouCompleteMe/
安装遇到找不到ycmd/build.py
[root@vm01 YouCompleteMe]# ./install.py -clang-completer
File /root/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py does not exist; you probably forgot to run:
	git submodule update --init --recursive
 
[root@vm01 YouCompleteMe]# cd ..
[root@vm01 bundle]# mv YouCompleteMe y
[root@vm01 bundle]# git clone https://github.com/Valloric/YouCompleteMe.git
[root@vm01 bundle]# cd YouCompleteMe/
再次安装
[root@vm01 YouCompleteMe]# ./install.sh
WARNING: this script is deprecated. Use the install.py script instead.

安装遇到c++编译器不支持
[root@vm01 YouCompleteMe]# ./install.py --clang-completer

.vimrc配置中，上面一段是启用Vundle，并且安装2个插件gmarik/Vundle.vim 和 vim-scripts/indentpython.vim，即github的项目名称。接着是安装Valloric/YouCompleteMe插件，此插件比较大。再往下依次是vim原来的设置、python缩进、pyenv的设置。完成后上面.vimrc配置文件后，就在vim安装插件吧。

输入vim后，再输入”:BundleInstall”或者”:PluginInstall” 即可安装，因为YouCompleteMe比较大，所以安装要一小时，我这里上传到了网盘(https://pan.baidu.com/s/1nvhm4op)，vimrc的配置在.vim文件夹内，在root目录下解压缩vim.tar.gz ,复制.vim/.vimrc到根目录即可。这样就完事了。

发现另外一个python的vim插件：python-mode，上面的配置文件YouCompleteMe就不用安装了。在配置中添加如下安装

Bundle ‘klen/python-mode’ 即可，所以.vimrc文件如下：

# cat ~/.vimrc 
set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'gmarik/Vundle.vim'
call vundle#end()            
filetype plugin indent on 
 
Bundle 'klen/python-mode'
 
syntax on
set nohlsearch
set encoding=utf-8
 
py << EOF
import os
import sys
if 'VIRTUAL_ENV' in os.environ:
	project_base_dir = os.environ['VIRTUAL_ENV']
	activate_this = os.path.join(project_base_dir, 'bin/activate_this.py')
	execfile(activate_this, dict(__file__=activate_this))
EOF

编辑好.vimrc文件，打开vim，输入 :PluginInstall 即可安装模块，安装完成后就可以使用
