官网中对应的页面如下

1 筹备

  • vscode 软件
  • C/C++ Extension Pack 插件

  • clang/clang++ 编译器

    • 查看已装置clang++

      clang++ -v
    • 如果未装置,请返回 app store 下载 xcode

2 .vscode配置

在当前工作区筹备以下文件(夹)

  • .vscode

    • tasks.json # 用于编译c++文件
    • launch.json # 用于应用vscode自带的debug工具(左侧的小虫图标)
    • c_cpp_properties.json # 用于应用vscode自带的代码提醒工具如 IntelliSense
  • main.cpp

    #include <iostream>#include <vector>#include <string>using namespace std;int main(){    vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};    for (const string& word : msg)    {        cout << word << " ";    }    cout << endl;}

配置tasks.json

command + shift + b,vscode会执行tasks.json中的工作。

本文配置的是c++编译,替换tasks.json的内容如下:

{  "version": "2.0.0",  "tasks": [    {      "label": "Build with Clang", //这个工作的名字在launch.json最初一项配置      "type": "shell",      "command": "clang++",      "args": [        "-std=c++17",        "-stdlib=libc++",        "-g",        // 生成调试信息,GUN可应用该参数        "${file}",        // file指正在关上的文件        "-o",        // 生成可执行文件        "${fileDirname}/${fileBasenameNoExtension}"        // fileDirname指正在关上的文件所在的文件夹        // fileBasenammeNoExtension指没有扩展名的文件,unix中可执行文件属于此类      ],      "options": {        "cwd": "${workspaceFolder}"      },      "problemMatcher": ["$gcc"],      "group": {        "kind": "build",        "isDefault": true      }    }  ]}

关上main.cpp,按command + shift + b(留神,按这组快捷键时main.cpp文件在vscode中是正在关上的),如下图

工作区中没有扩展名的main就是在mac os下生成的可执行文件(同理,如果是windows,有扩展名.exe)

在vscode内置的终端中,能够运行main,如下图:

配置 c_cpp_properties.json

c_cpp_properties.json 的作用是:代码提醒、代码跳转等

{  "configurations": [    {      "name": "Mac",      "includePath": [        "${workspaceFolder}/**",        "/Library/Developer/CommandLineTools/usr/include",        "/Library/Developer/CommandLineTools/usr/lib/clang/11.0.3/include",        // 请依据你的clang版本批改,我这里是11.0.3        "/usr/local/include"      ],      "defines": [],      "macFrameworkPath": [        "/System/Library/Frameworks",        "/Library/Frameworks"      ],      "compilerPath": "/usr/bin/clang++",      "cStandard": "c11",      "cppStandard": "c++17",      "intelliSenseMode": "clang-x64"      // "compileCommands": "${workspaceFolder}/build/compile_commands.json"    }  ],  "version": 4}

配置launch.json

launch.json是调用vscode debug性能的配置文件

{  "version": "0.2.0",  "configurations": [    {      "type": "lldb",      "request": "launch",      "name": "Debug",      "program": "${workspaceFolder}/${fileBasenameNoExtension}",      "args": [],      "cwd": "${workspaceFolder}",      "preLaunchTask": "Build with Clang"    }  ]}

关上debug窗口,打好断点,按下图操作

这三个配置文件中的参数阐明,在官网都有,我把一部分写在了正文里
