安裝VS Code

https://code.visualstudio.com/

sudo dpkg -i code_xxxx_amd64.deb

安裝插件

GNU Global

sudo apt install global

# 在工程目錄執(zhí)行以便建立索引
gtags -v

# 增量更新索引
gtags -vi

# 查找函數(shù)或變量的定義和申明
global -x <variable name or function name>

# 查找函數(shù)或變量的引用
global -xr <variable name or function name>

生成三個(gè)文，GTAGS是定義的數(shù)據(jù)庫(kù)，GRTAGS是引用的數(shù)據(jù)庫(kù)，GPATH是路徑的數(shù)據(jù)庫(kù)

右鍵即可使用Go to Definition、Peak Definition、Find All References

Lint

sudo apt install clang
sudo apt install cppcheck

違反語(yǔ)言規(guī)則或則檢查規(guī)則，將在違規(guī)處顯示告警信息，能顯著減少編譯時(shí)間，提高效率。

CMake

sudo apt install cmake

# 創(chuàng)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，其他工程也類似

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

自動(dòng)生成“.vscode/c_cpp_properties.json”，在“includePath”中增加頭文件路徑

設(shè)置垂直標(biāo)尺

打開(kāi)"settings"，所有“editor.rulers”，點(diǎn)擊“settings.json”

填入120，表示120個(gè)字符。下圖右邊為垂直標(biāo)尺。

格式化文件

可自定義代碼格式，并將名為“.clang-format”的格式文件放到VS Code工程根目錄。

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

自定義格式，參考 https://zhuanlan.zhihu.com/p/356143396

快捷鍵：ctrl + shift + I

或則右鍵并選擇Format Document

重命名

選擇需重名的Symbol，右鍵并選擇“Rename Symbol”，輸入New Symbol

按“Shift+Enter”，然后選擇需要修改的代碼，并按“Shift+Enter“

Git

在“Source Control”進(jìn)行操作

Remote - SSH

配置和使用請(qǐng)參考：

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

公司的辦公環(huán)境一般是window，開(kāi)發(fā)環(huán)境為ubuntu。通過(guò)此插件連接到ubuntu進(jìn)行開(kāi)發(fā)，大部分功能是在ubuntu上執(zhí)行，PC僅顯示和編輯代碼。

備注: 連接到Remote Server，須選擇本地的插件安裝到Remote server

代理

由于數(shù)據(jù)安全，大公司會(huì)屏蔽部分外網(wǎng)功能并提供代理服務(wù)。

打開(kāi)“settings”，搜索“proxy”，在“Http:Proxy”中輸入代理網(wǎng)址
