Vim编辑器配置

安装 cmake

sudo apt-get install cmake

安装Vim

sudo apt-get install vim

vim 的配色最好和终端的配色保持一致

git clone git://github.com/altercation/solarized.git
$ cd solarized
$ cd vim-colors-solarized/colors
$ mkdir -p ~/.vim/colors
$ cp solarized.vim ~/.vim/colors/

$ vi ~/.vimrc
syntax on
set background=dark
colorscheme solarized

下载Vundle管理插件到目录

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

安装Vundle插件，编辑~/.vimrc文件

set nocompatible              " required
filetype off                  " required
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'gmarik/Vundle.vim'
call vundle#end()            " required
filetype plugin indent on    " required
set nu
set mouse=a

vim 安装插件

$ vim           # 进入 vim 界面
:PluginInstall  # 进入安装

安装 YouCompleteMe

修改 .vimrc 文件，再次执行安装，在 call vundle#begin() 和 call vundle#end() 中间添加一行

Plugin 'Valloric/YouCompleteMe'

安装出现错误，忽略，进行下一步,编译 YouCompleteMe --clang-completer 参数实现对 c/c++ 语法支持

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

YouCompleteMe 安装完成，再执行 :PluginInstall 就没有错误了

配置代码自动补全

设置全局配置文件路径 ~/.vimrc

let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'

配置 .ycm_extra_conf.py

sudo apt-get install clang
echo | clang -v -E -x c++ -

将输出结果位于

#include "..." search starts here:
#include <...> search starts here:
和
End of search list.z
之间的部分添加到 .ycm_extra_conf.py 文件中
注意每条路径都要匹配一条语句 '-isyetem'

完善配置文件 .vimrc

代码自动格式化

vim-autoformat + astyle

安装 vim-autoformat

Plugin 'Chiel92/vim-autoformat'

astyle在线或者源码编译安装 make、make install

apt-get install astyle

利用 astyle 格式化

map <F4> :call FormatCode()<CR>
func! FormatCode()
    exec "w"
	if &filetype == 'C' || &filetype == 'h'
		exec "!astyle --style=allman --pad-oper %"
    elseif &filetype == 'cpp'
       	exec "!astyle --style=allman --pad-oper %"
    return
    endif
endfunc

利用 vim-autoformat 格式化，具体需要那种格式请看 astyle 文档

let g:formatdef_allman = '"astyle --style=allman --pad-oper"'
let g:formatters_cpp = ['allman']
let g:formatters_java = ['allman']
noremap <F5> :Autoformat<CR>
