安装VS Code

https://code.visualstudio.com/

sudo dpkg -i code_xxxx_amd64.deb

安装插件

GNU Global

sudo apt install global

# 在工程目录执行以便建立索引
gtags -v

# 增量更新索引
gtags -vi

# 查找函数或变量的定义和申明
global -x <variable name or function name>

# 查找函数或变量的引用
global -xr <variable name or function name>

生成三个文，GTAGS是定义的数据库，GRTAGS是引用的数据库，GPATH是路径的数据库

右键即可使用Go to Definition、Peak Definition、Find All References

Lint

sudo apt install clang
sudo apt install cppcheck

违反语言规则或则检查规则，将在违规处显示告警信息，能显著减少编译时间，提高效率。

CMake

sudo apt install cmake

# 创建CMake工程
CMake:Quick Start

# 常用功能
CMake:Configure
CMake:Build
CMake:Clean
CMake:Run
CMake:Debug
CMake:Install

C/C++

如下配置用于研究linux kernel，其他工程也类似

Ctrl + Shift + P >> “C/C++:Edit configurations…(json)”

自动生成“.vscode/c_cpp_properties.json”，在“includePath”中增加头文件路径

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/include/**",

                "${workspaceFolder}/arch/arm64/**",
                "${workspaceFolder}/arch/arm64/include/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",

            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

Ctrl + Shift + P >> Preferences: Open Workspace Settings (JSON)

自动生成“.vscode/settings.json”

设置垂直标尺

打开"settings"，所有“editor.rulers”，点击“settings.json”

填入120，表示120个字符。下图右边为垂直标尺。

格式化文件

可自定义代码格式，并将名为“.clang-format”的格式文件放到VS Code工程根目录。

sudo apt install clang-format
# 生成llvm风格的格式
clang-format -style="{BasedOnStyle: llvm, IndentWidth: 4}" -dump-config > .clang-format
# 生成google风格的格式
clang-format -style="{BasedOnStyle: google, IndentWidth: 4}" -dump-config > .clang-format

自定义格式，参考 https://zhuanlan.zhihu.com/p/356143396

快捷键：ctrl + shift + I

或则右键并选择Format Document

重命名

选择需重名的Symbol，右键并选择“Rename Symbol”，输入New Symbol

按“Shift+Enter”，然后选择需要修改的代码，并按“Shift+Enter“

Git

在“Source Control”进行操作

Remote - SSH

配置和使用请参考：

https://code.visualstudio.com/docs/remote/ssh#_getting-started

公司的办公环境一般是window，开发环境为ubuntu。通过此插件连接到ubuntu进行开发，大部分功能是在ubuntu上执行，PC仅显示和编辑代码。

备注: 连接到Remote Server，须选择本地的插件安装到Remote server

代理

由于数据安全，大公司会屏蔽部分外网功能并提供代理服务。

打开“settings”，搜索“proxy”，在“Http:Proxy”中输入代理网址
