vi安装Vundle+YouCompleteMe+注释快捷'scrooloose/nerdcommenter'

Vundle is short for Vim bundle and is a Vim plugin manager.

• 从git上下载vundle

　　　　$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

• 配置vundle插件

1. 1. Put this at the top of your .vimrc to use Vundle. Remove plugins you don't need, they are for illustration purposes.

      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'}

      "下面这行是添加YouCompleteMe插件
      Bundle 'Valloric/YouCompleteMe'
      "下面这行是添加注释插件，可以\cc注释，用\cu取消注注释
      Bundle 'scrooloose/nerdcommenter'
      " 所有vundle管理的插件都要在下面这行结束之前写好
      call vundle#end()            " required
      filetype plugin indent on    " required
      " To ignore plugin indent changes, instead use:
      "filetype plugin on
      "
      " Brief help 下面是vi中的命令,可以打开vim之后命令模式下输入执行
      " :PluginList       - lists configured plugins
      " :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
      " :PluginSearch foo - searches for foo; append `!` to refresh local cache
      " :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
      "
      " see :h vundle for more details or wiki for FAQ
      " 下面可以加一些其它的自定义vi配置，比如说：
      set number
      set autoindent
      set cindent
      syntax enable
      syntax on
      "set c_Coo=256
      set backspace=indent,eol,start
      set tabstop=4
      set shiftwidth=4
      set smarttabet 
      "set softabstop=4
      set expandtab
      set encoding=utf-8
      set fileencodings=ucs-bom,utf-8,cp936,gb18030,big5,euc-jp,euc-kr,lantin1
      filetype on
      filetype indent on
      filetype plugin indent on

   2. 下载插件:

      打开vim并运行命令 :PluginInstall,会自动把上面添加的YouCompleteMe下载到~/.vim/bundle/YouCompleteMe

      To install from command line: vim +PluginInstall +qall

 

• 下载完成YouCompleteMe后，需要对其进行编译安装

  cd ~/.vim/bundle/YouCompleteMe
  ./install --clang-completer 

这里需要安装有python-dev和cmake包

打开vim时提示No .ycm_extra_conf.py file detected, so no compile flags are available. Thus no semantic support for C/C++/ObjC/ObjC++.。只需要设置.ycm_extra_conf.py文件的位置即可，在.virmc文件中添加如下内容let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'，如果该路径下没有，有可能 在let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'，然后重新打开vim即可。

• 配置YouCompleteMe

"下面这部分没改

为了补全C++代码，在Linux下我们需要修改.ycm_extra_conf.py文件中的flags部分，使用-isystem添加系统的头文件进行解析，使用-I添加第三方的头文件进行解析，在flags部分后添加如下内容：

'-isystem',

'/usr/include',

'-isystem',

'/usr/include/c++/4.8',

10. '-isystem',

11. '/usr/include',

12. '/usr/include/x86_64-linux-gun/c++',

使用YouCompleteMe进行代码跳转可以通过绑定一个快捷键：nnoremap <leader>jd :YcmCompleter GoToDefinitionElseDeclaration<CR>，很好理解，先跳到定义，如果没找到，则跳到声明处。\jd　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

From <http://feihu.me/blog/2014/intro-to-vim/>

:help map可以进入vi的快捷键的相关帮助文档

例如，本来需要按\jd转到变量的定义，那么现在只要按,jd就可以了

~/.vimrc：
let leader=','
letg:mapleader=','
nnoremap <leader>jd:Ycmcompleter GoToDefinitionElseDeclaration<CR>
