Linux主机:Ubuntu 16.04 x64

一、手动安装YouCompleteMe

1.确保vim至少是 7.4.143并且支持python2或者python3

在命令行中输入vim --version,我的输出如图1:

2.安装YCM

3.语义支持

wget http://releases.llvm.org/3.9.1/clang+llvm-3.9.1-x86_64-linux-gnu-ubuntu-16.04.tar.xz
tar -Jxvf clang+llvm-3.9.1-x86_64-linux-gnu-ubuntu-16.04.tar.xz 
cd clang+llvm-3.9.1-x86_64-linux-gnu-ubuntu-16.04/
sudo cp -r * /usr/local #将对应的文件拷贝到/usr/local中的对应目录
clang --version #测试安装
    clang version 3.9.1 (tags/RELEASE_391/final)
    Target: x86_64-unknown-linux-gnu
    Thread model: posix
    InstalledDir: /usr/local/bin

4.编译ycm_core库

安装依赖项:

sudo apt-get install cmake
sudo apt-get install python-dev python3-dev

然后执行一下命令:

#创建编译目录
cd ~/.vim
mkdir ycm_build
cd ycm_build
#生成makefiles,这里LLVM参数指定clang位置,我安装位置/usr/local
cmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=/usr/local . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp
#成功的输出如下:

二、配置YouCompleteMe

"YouCompleteMe配置 
"默认配置文件路径"
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'
"打开vim时不再询问是否加载ycm_extra_conf.py配置"
let g:ycm_confirm_extra_conf=0
"让Vim的补全菜单行为与一般IDE一致
set completeopt=longest,menu
"python解释器路径"
let g:ycm_path_to_python_interpreter='/usr/bin/python'
"是否开启语义补全"
let g:ycm_seed_identifiers_with_syntax=1
"是否在注释中也开启补全"
let g:ycm_complete_in_comments=1
let g:ycm_collect_identifiers_from_comments_and_strings = 0
"开始补全的字符数"
let g:ycm_min_num_of_chars_for_completion=2
"补全后自动关闭预览窗口"
let g:ycm_autoclose_preview_window_after_completion=1
" 禁止缓存匹配项,每次都重新生成匹配项"
let g:ycm_cache_omnifunc=0
"字符串中也开启补全"
let g:ycm_complete_in_strings = 1
"离开插入模式后自动关闭预览窗口"
autocmd InsertLeave * if pumvisible() == 0|pclose|endif
 "上下左右键的行为 会显示其他信息
inoremap       pumvisible() ? "\" : "\"
inoremap         pumvisible() ? "\" : "\"
inoremap   pumvisible() ? "\\\" : "\"
inoremap     pumvisible() ? "\\\" : "\"

flags = [
'-Wall',
'-Wextra',
'-Werror',
'-Wno-long-long',
....省略...
'./tests/gmock',
'-isystem',
'./tests/gmock/include',
]

'-isystem',
'/usr/include',
'-isystem',
'/usr/include/c++/5.4.0',
'-isystem',
'/usr/include',
'/usr/include/x86_64-linux-gnu/c++',

注意每加入一个路径,都要加入一句 '-isystem',

一个简单的效果如图2:

三、一些问题

有时候中英文混合书写的时候,YouCompleteMe有时候不会自动弹出补全框,这个时候你可以使用vim自己带的补全工具, 快捷键是 ctrl+n 或者 ctrl+p

Windows主机:Windows 10 x64

一、依赖软件

• Python2 x64 && Python3 x64
  注意64位系统下载64位的Python,32位系统下载32位Python.如果你打算使用Python3编译,那 么你最好先安装Python3,然后再安装Python2.
• CMake
  下载完成后,需要将其添加到环境变量,在执行如下命令前请注意不要敲错命令看错说明, 这话我已经说了,搞错环境变量的话,后果自己承担,否则字节老老实实用GUI的方式添加环境 变量去吧.命令行添加环境变量的方法为: wmic environment where 'UserName="<system>" and name="Path"' set VariableValue="%Path%;C:\Users\Programs\cmake\bin" 注意将其中的C:\Users\Programs\cmake\bin替换为你自己的路径.
• Visual Studio
  自己去下载社区版本的安装即可,建议下载安装Visual Studio 2015.
• 7-zip
  下载完毕后,设置环境变量: wmic environment where 'UserName="<system>" and name="Path"' set VariableValue="%Path%;C:\Users\Programs\7-Zip" 注意将其中的C:\Users\Programs\7-Zip修改为你自己的安装目录.
• 在vim中安装YCM
  打开vim的配置文件_vimrc,添加 Plugin 'Valloric/YouCompleteMe',然后执行:PluginInstall来安装.
• 安装clang
  安装过程中选择将LLVM添加到环境变量中去.

二、编译YCM

进入vimfiles目录(位于$VIM/vimfiles),新建ycm_build目录,然后进入ycm_build目录.执行下面的命令:

cmake -G "Visual Studio 14 2015 Win64" -DPATH_TO_LLVM_ROOT="C:\Users\Programs\LLVM" .  "C:\Users\Programs\Vim\vimfiles\bundle\YouCompleteMe\third_party\ycmd\cpp" -DPYTHON_INCLUDE_DIR="C:\Users\Programs\Python3\include" -DPYTHON_LIBRARY="C:\Users\Programs\Python3\libs\python36.lib" -DUSE_PYTHON2=OFF

上面的"Visual Studio 14"可以打开你的 Visual Studio 安装目录,在路径中你可以看到那个 数值,更换为你的即可.成功输出如下:

-- The C compiler identification is MSVC 19.0.24215.1
-- The CXX compiler identification is MSVC 19.0.24215.1
-- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/x86_amd64/cl.exe

-- Looking for pthread.h
-- Looking for pthread.h - not found
-- Found Threads: TRUE
-- Configuring done
-- Generating done
-- Build files have been written to: C:/Users/Programs/Vim/vimfiles/ycm_build

现在开始编译:

 cmake --build . --target ycm_core --config Release 

编译成功后,配置_vimrc,在其中加入:

let g:ycm_global_ycm_extra_conf = 'C:\Users\Programs\Vim\vimfiles\bundle\YouCompleteMe\third_party\ycmd\cpp\ycm\.ycm_extra_conf.py'

"打开vim时不再询问是否加载ycm_extra_conf.py配置"
let g:ycm_confirm_extra_conf=0
"让Vim的补全菜单行为与一般IDE一致
set completeopt=longest,menu
"python解释器路径"
let g:ycm_path_to_python_interpreter='C:\Users\Programs\Python3/python.exe'
"是否开启语义补全"
let g:ycm_seed_identifiers_with_syntax=1

"是否在注释中也开启补全"
let g:ycm_complete_in_comments=1
let g:ycm_collect_identifiers_from_comments_and_strings = 0
"开始补全的字符数"
let g:ycm_min_num_of_chars_for_completion=2
"补全后自动关闭预览窗口"
let g:ycm_autoclose_preview_window_after_completion=1
" 禁止缓存匹配项,每次都重新生成匹配项"
let g:ycm_cache_omnifunc=0
"字符串中也开启补全"
let g:ycm_complete_in_strings = 1
"离开插入模式后自动关闭预览窗口"
autocmd InsertLeave * if pumvisible() == 0|pclose|endif

 "上下左右键的行为 会显示其他信息
inoremap       pumvisible() ? "\" : "\"
inoremap         pumvisible() ? "\" : "\"
inoremap   pumvisible() ? "\\\" : "\"
inoremap     pumvisible() ? "\\\" : "\"

然后再.ycm_extra_conf.py中的flags数组中加入如下语句:

'-isystem',
'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include',

WMIC命令

wmic 命令可以方便的设置环境变量,wmic environment相当于一个数据库, 该数据库的属性包括8个,分别为:

Caption,Description,InstallDate,Name,Status,SystemVariable,UserName,VariableValue

举两个例子:

<SYSTEM>\Path,<SYSTEM>\Path,Path,OK,TRUE,<SYSTEM>,%SystemRoot%\system32;%SystemRoot%
BLABLAHAHAHA\Administrator\TEMP,BLABLAHAHAHA\Administrator\TEMP,TEMP,OK,FALSE,BLABLAHAHAHA\Administrator,%USERPROFILE%\AppData\Local\Temp

以上面的例子来说明这8个属性,Caption指当前环境变量的具体归属, 比如说, <system>\Path 具体指定了系统归属里的 Path 环境变量,而 BLABLAHAHAHA\Administrator\TEMP 则指明了当前用户归属里的 TEMP 环境变量, Description是对当前环境变量的额外描述,但是一般默认情况下和 Caption 一样, InstallDate一般不用,设置为空.Name比较重要,指定了当前归属的环境变量名称, Status一般均设置为OK,SystemVariable指明当前环境变量是否为系统环境变量,如果是, 则为TRUE,若不是则为FALSE.然后是UserName,这个属性比较重要,它从整体上指明了要查询的环境 变量归属范围,最后的属性 VariableValue 指明了环境变量的值.这8个属性我们只需要关注3个, 分别是 UserName,Name,VariableValue

环境变量的归属,一般地我们用的就两个,一个是系统,一个是用户. 系统的名称在 wmic 中总是 <system>,而用户则是当前用户,其名称可以用 whoami 来获得.更直观的,下面是系统自带的GUI环境变量设置界面:

标记1处为环境变量的用户归属,而标记2处为环境变量的系统归属即 <system>. 现在我们可以使用wmic命令来增删改查环境变量了.

增加:
wmic environment create UserName="<system>",name="Hello",VariableValue="World"
修改:
wmic environment where 'UserName="<system>" and name="Hello"' set VariableValue="AnotherWorld"
查询:
wmic environment where 'UserName="<system>" and name="Hello"' get VariableValue
删除:
wmic environment where 'UserName="<system>" and name="Hello"' delete
注意where后面的语句需要用引号括起来,另外,如果UserName中有反斜线,比如说你的当前用户名 字为blablahahaha\administrator,那么你需要写成UserName="blablahahaha\\administrator"才可以.

2017-09-27/自定义项目补全

当我们自己写项目时,可能包含了一些头文件或者包,我们只需要将 .ycm_confirm_extra_conf.conf 拷贝到自己项目的顶级目录下面即可. 无须做任何修改,然后重新启动 vim,就可以补全自己头文件里面的类方法或者包方法.
