• vim下使用YouCompleteMe实现代码提示、补全以及跳转设置


    配置YouCompleteMe

    1. 安装vundle

    vundle是一个管理vim插件的工具,使用vundle安装YouCompleteMe比较方便。

    按照作者在https://github.com/gmarik/Vundle.vim#about提供的方法安装好vundle。(主要是下载解压,病略微修改 .vimrc)

    2. 使用vundle安装YouCompleteMe

    主要根据作者自己的建议整理 https://github.com/Valloric/YouCompleteMe

    在.vimrc中 vundle部分,添加一行:

    Plugin ‘Valloric/YouCompleteMe‘

    然后,打开vim,输入命令

    :PluginInstall

    就会开始自动安装vundle指定的各种插件。

    由于要安装clang等,安装过程是非常久的,大概需要一个小时,这个时间完全可以去做些别的。

    等安装好后,在.vim/vundle/YouCompleteMe目录下多了一堆目录和文件。

    3. 使用YouCompleteMe

    YouCompleteMe进行补全时需要查找一个 ycm_global_ycm_extra_conf文件。可以每次在工作目录中放置这个文件,也可以设置全局。全局设置要在.vimrc中添加一行

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

    4. 效果图

    主要参考http://www.cnblogs.com/ma6174/archive/2011/12/10/2283393.html。 加入了前面介绍的ctags, YouCompleteMe的配置。1 " Suzzz 2014.11.03

      3 " 额外添加了 ctags, YouCompleteMe等
      4 "  主要特点
      5 
      6 "1.按F5可以直接编译并执行C、C++、java代码以及执行shell脚本,按“F8”可进行C、C++代码的调试
      7 "2.自动插入文件头 ,新建C、C++源文件时自动插入表头:包括文件名、作者、联系方式、建立时间等,读者可根据需求自行更改
      8 "3.映射“Ctrl + A”为全选并复制快捷键,方便复制代码
      9 "4.按“F2”可以直接消除代码中的空行
     10 "5.“F3”可列出当前目录文件,打开树状文件目录
     11 "6. 支持鼠标选择、方向键移动
     12 "7. 代码高亮,自动缩进,显示行号,显示状态行
     13 "8. 按“Ctrl + P”可自动补全
     14 "9. []、{}、()、""、‘ ‘等都自动补全   --- 如果需要{}做函数形式的补全(右括号自动换行,加一个空行,光标定位到空行,可以看下面的修改提示)
     15 "10. 使用YouCompleteMe提供C++的自动补全提示,效果类似 Visual Studio那种,可以解析系统头文件

     配置

    不同于很多vim插件,YCM首先需要编译,另外还需要有配置。在vim启动后,YCM会找寻当前路径以及上层路径的.ycm_extra_conf.py.在~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py中提供了默认的模板。也可以参考我的(就在模板上改改而已)。不过这个解决了标准库提示找不到的问题。

    一般来说,我会在~目录下放一个默认的模板,而后再根据不同的项目在当前目录下再拷贝个.ycm_extra_conf.py。

    YouCompleteMe提供的其他功能

    YCM除了提供了基本的补全功能,自动提示错误的功能外,还提供了类似tags的功能:

    • 跳转到定义GoToDefinition
    • 跳转到声明GoToDeclaration
    • 以及两者的合体GoToDefinitionElseDeclaration

    可以在.vimrc中配置相应的快捷键。

    1
    2
    3
    nnoremap <leader>gl :YcmCompleter GoToDeclaration<CR>
    nnoremap <leader>gf :YcmCompleter GoToDefinition<CR>
    nnoremap <leader>gg :YcmCompleter GoToDefinitionElseDeclaration<CR>

    另外,YCM也提供了丰富的配置选项,同样在.vimrc中配置。具体请参考

    1
    2
    let g:ycm_error_symbol = '>>'
    let g:ycm_warning_symbol = '>*'

    同时,YCM可以打开location-list来显示警告和错误的信息:YcmDiags。个人关于ycm的配置如下:

    1
    2
    3
    4
    5
    6
    7
    " for ycm
    let g:ycm_error_symbol = '>>'
    let g:ycm_warning_symbol = '>*'
    nnoremap <leader>gl :YcmCompleter GoToDeclaration<CR>
    nnoremap <leader>gf :YcmCompleter GoToDefinition<CR>
    nnoremap <leader>gg :YcmCompleter GoToDefinitionElseDeclaration<CR>
    nmap <F4> :YcmDiags<CR>

    YCM提供的跳跃功能采用了vim的jumplist,往前跳和往后跳的快捷键为Ctrl+O以及Ctrl+I。

    总结

    YouCompleteMe是我用过的最爽的一个自动补全的插件了。之前使用acp时,遇到大文件基本上就卡死了,以至于都不怎么敢使用。由于YCM使用的时C/S结构,部分使用vim脚本编写,部分认为原生代码,使得跑起来速度飞快。

    抛弃Vim自带的坑爹的补全吧,抛弃ctags吧,抛弃cscope吧,YCM才是终极补全神器。
