一、是什么？

二、使用步骤

1.引入库

代码如下（示例）：

launch.json

{
  // One of the key features of Visual Studio Code is its great debugging support.
  // VS Code's built-in debugger helps accelerate your edit, compile and debug loop.
  // VS Code keeps debugging configuration information in a launch.json file
  // located in a .vscode folder in your workspace (project root folder).
  "version": "0.2.0",
  "configurations": [
    {
      /* ------ these three options are mandatory ------ */
      // The type of debugger to use for this launch configuration.
      "type": "cppdbg", // C++ debug
      // The request type of this launch configuration. Currently, launch and attach are supported.
      //   If you come from a server or desktop background, 
      //   it's quite normal to have your editor launch your process for you, 
      //   and your editor automatically attaches its debugger to the newly launched process.
      //   A launch configuration starts your app in debug mode before VS Code attaches to it.
      // 大概意思是说，如果你开始debug的时候你的项目已经启起来了，那就attach（把debug的工具附加上去）
      // 如果你开始debug的时机和你启动项目的时机是相同的，那就launch
      "request": "launch", // debug的类型，launch表示启动，attach表示附加
      // The reader-friendly name to appear in the Debug launch configuration drop-down.
      "name": "C++ Debug", // 在VSCode侧边栏Run那里看到的名字（可以随便起）
      /* ------ some optional attributes available to all launch configurations ------ */
      // To launch a task before the start of a debug session, set this attribute to the label of a task specified in tasks.json.
      "preLaunchTask": "g++ compile", //在调试之前要进行的工作 compile是在 tasks.json 的编译任务里面的label
      /* ------ Many debuggers support some of the following attributes: ------ */
      // executable or file to run when launching the debugger
      // ！！不要在程序和代码的路径及文件名中出现空格！！否则无法调试（我尝试解决这个问题，但真的无法解决）
      "program": "${fileDirname}/${fileBasenameNoExtension}.out", // debug的对象(-g编译出来的二进制文件)，需要和.vscode/tasks.json中生成的可执行文件一致
      // arguments passed to the program to debug
      "args": [], // 比如运行你的程序添加输入参数（argc/argv），需要在这里添加
      // Environment variables to add to the environment for the program
      "environment": [], // 放置环境变量
      // current working directory for finding dependencies and other files
      "cwd": "${workspaceFolder}",
      // break immediately when the program launches
      "stopAtEntry": false,
      // If true, a console is launched for the debuggee.
      // If false, on Linux and Windows, it will appear in the Integrated Console.
      "externalConsole": true,
      // 为true则会打开系统终端在其中进行交互
      // 如果为 true，则为调试对象启动控制台。如果为 false，它在 Linux 和 Windows 上会显示在集成控制台中
      // macOS不适用：https://code.visualstudio.com/docs/cpp/launch-json-reference#_externalconsole
      /* ------ Customizing GDB or LLDB ------ */
      // Indicates the debugger that VS Code will connect to. Must be set to gdb or lldb. 
      // 但是macOS只安装了llbd（有可能是安装命令行工具的时候安装的），那就用lldb吧
      "MIMode": "lldb",
    }
  ]
}

2.tasks.json

代码如下（示例）：

{
  // Tasks in VS Code can be configured to run scripts and start processes
  // so that many of these existing tools can be used from within VS Code 
  // without having to enter a command line or write new code.
  // Workspace or folder specific tasks are configured from the tasks.json file in the .vscode folder for a workspace.
  "version": "2.0.0",
  "tasks": [
    {
      // The task's label used in the user interface.
      // Terminal -> Run Task... 看到的名字
      "label": "g++ compile",
      // The task's type. For a custom task, this can either be shell or process.
      // If shell is specified, the command is interpreted as a shell command (for example: bash, cmd, or PowerShell).
      // If process is specified, the command is interpreted as a process to execute.
      "type": "shell",// shell: 输入命令
      // The actual command to execute.
      // 因为g++已经在环境变量中了，所以我们这里写命令就行不用写g++的绝对路径
      "command": "g++",
      "args": [
        "${file}", // 表示当前文件（绝对路径）
        // 在这里添加你还需要链接的.cpp文件
        "-o",
        "${fileDirname}/${fileBasenameNoExtension}.out",
        "-W",
        "-Wall",
        "-g",
        "-std=c++17",
      ],
      // Defines to which execution group this task belongs to.
      // It supports "build" to add it to the build group and "test" to add it to the test group.
      // Tasks that belong to the build/test group can be executed by running Run Build/Test Task from the Command Palette (sft cmd P).
      // Valid values:
      //   "build",
      //   {"kind":"build","isDefault":true}, 
      //   "test",
      //   {"kind":"test","isDefault":true}, 
      //   "none".
      "group": {
        "kind": "build",
        "isDefault": true, // Defines if this task is the default task in the group.
      },
      // Configures the panel that is used to present the task's output and reads its input.
      "presentation": {
        // Controls whether the executed command is echoed to the panel. Default is true.
        "echo": true, // 打开可以看到编译的命令，把命令本身输出一次
        // Controls whether the terminal running the task is revealed or not. Default is "always".
        //   always: Always reveals the terminal when this task is executed.
        //   silent: Only reveals the terminal if the task exits with an error or the problem matcher finds an error.(会显示错误，但不会显示警告)
        //   never: Never reveals the terminal when this task is executed.
        "reveal": "silent", // 控制在集成终端中是否显示。如果没问题那我不希望终端被切换、如果有问题我希望能看到编译过程哪里出错，所以选silent(可能always会好一些)
        // Controls whether the panel takes focus. Default is false.
        "focus": false, // 我的理解是：是否将鼠标移过去。因为这个是编译任务，我们不需要输入什么东西，所以选false
        // Controls if the panel is shared between tasks, dedicated to this task or a new one is created on every run.
        "panel": "shared", // shared:不同任务的输出使用同一个终端panel（为了少生成几个panel我们选shared）
        // Controls whether to show the `Terminal will be reused by tasks, press any key to close it` message.
        "showReuseMessage": true, // 就一句话，你想看就true，不想看就false
        // Controls whether the terminal is cleared before executing the task.
        "clear": false, // 还是保留之前的task输出信息比较好。所以不清理
      },
      // Other two choices: options & runOptions (cmd I to use IntelliSense)
      "options": {
        // The current working directory of the executed program or script. If omitted Code's current workspace root is used.
        "cwd": "${workspaceFolder}",// 默认就是这个，删掉也没问题
      },
      // problemMatcher: 用正则表达式提取g++的输出中的错误信息并将其显示到VS Code下方的Problems窗口
      // check: https://code.visualstudio.com/docs/editor/tasks#_defining-a-problem-matcher
      "problemMatcher": {
        "owner": "cpp",
        "fileLocation": "absolute",
        "pattern": {
          "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
          "file": 1,
          "line": 2,
          "column": 3,
          "severity": 4,
          "message": 5,
        },
      },
      // 官网教程 https://code.visualstudio.com/docs/cpp/config-clang-mac#_build-helloworldcpp 
      // 提到了另一种problemMatcher，但试了之后好像不起作用，甚至还把我原本的电脑搞出了一些问题……
    },
