vim插件和配置

插件

pathogen 能够方便地管理vim插件

在没有pathogen的状况下，vim插件的文件所有都放在.vim目录，卸载插件很麻烦，pathogen能够将不一样的插件放在一个单独的目录下，安装插件只须要将插件的文件夹复制到制定文件夹（bundle）内，卸载插件时只须要删除文件夹，方便好用。

如下插件均可以采用“下载zip包到vundle文件夹，解压zip包”的方法进行安装

配置

基本配置

按键映射

按键映射的配置都写在.vimrc中，.vimrc放在主目录

imap jk <ESC\>              " 按jk退出编辑状态，不再用小指头按Esc了
map wq <ESC>:wq<CR>         " 按wq就直接保存退出
imap wq <ESC>:wq<CR>        " 按wq就直接保存退出
map qq <ESC>:q!<CR>         " 按qq就直接不保存退出
imap qq <ESC>:q!<CR>        " 按qq就直接不保存退出
map <F2> <ESC><C-W><C-W>    " 按F2进行窗口切换，不按<C-W><C-W>
map <F3> <ESC>:Tagbar<CR>   " 按F3打开代码结构
map <F4> <ESC>:NERDTreeToggle<CR>
map <F12> <ESC>:!ctags -R --c++-kinds=+px --fields=+aiKSz --extra=+q .<CR>  " 按F12生成tag

ctrlp按键映射

map ,pp <ESC>:CtrlP<CR>             "搜索文件
map ,pd <ESC>:CtrlPDir<CR>          "搜索文件夹
map ,pu <ESC>:CtrlPUndo<CR>         "搜索修改记录，能够回退
map ,pl <ESC>:CtrlPLine<CR>         "搜索行
map ,pc <ESC>:CtrlPChangeAll<CR>    "搜索修改记录，能够定位光标
map ,pm <ESC>:CtrlPMRU<CR>          "搜索最近修改的文件

补全

vim中的自动补全很麻烦，可是写代码没有自动补全彻底没法接受。为了实现自动补全，我一开始使用omnicppcomplete和AutoComplPop，后来据说有个牛逼的插件叫作YouCompleteMe，能够进行语法分析，实现自动补全，因而我就去试试。咱们的开发机没法访问外网，也不能直接用root用户下直接安装软件，安装YouCompleteMe确实麻烦。我前后用源码编译安装了cmake、llvm、python、vim和YouCompleteMe，花了很多时间，终于把YouCompleteMe装好了，不过使用的时候，补全仍是不够智能，没有想象中那么好。后来搬到了新的开发机，不想再从新安装YouCompleteMe了，从新回到omnicppcomplete和AutoComplPop。最后我发现，omnicppcomplete和AutoComplPop实现的补全效果比YouCompleteMe好。几乎每一个vim使用者都会面临自动补全的功能，在这里，我建议使用omnicppcomplete和AutoComplPop组合，简单方便，效果又好。

由于项目是使用blade build编译，BUILD记录了项目的依赖，因而我写了一个python脚本去分析BUILD文件，获取相应的依赖，再根据依赖去生成tag，提升代码补全能力。最终，vim的代码补全能力也不错！使用方法以下：

1. 安装ctags、omnicppcomplete和AutoComplPop
2. 在vim中添加一句配置：set tags+=./deps_tags
3. 在BUILD所在目录下运行deps_tag.py脚本，根据依赖生成deps_tags
4. 按F12生成本项目的tags
5. 愉快地使用补全
6. 这里其实能够作到每次保存文件都自动从新生成tags，可是由于tags是根据所在工做路径的，若是不是在项目路径就会生成不必的tags

最后，欢迎使用个人vim配置
