1.先看上一篇文章
如果你还没有配置VSCode相关C++的环境和扩展，先看上一篇文章macOS使用VSCode编辑Cpp(c++)
2.tasks.json
这个是无注释的文件
{
"version": "2.0.0",
"tasks": [
{
"label": "g++ compile",
"type": "shell",
"command": "g++",
"args": [
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}.out",
"-W",
"-Wall",
"-g",
"-std=c++17"
],
"group": {
"kind": "build",
"isDefault": true
},
"presentation": {
"echo": true,
"reveal": "silent",
"focus": false,
"panel": "shared",
"showReuseMessage": true,
"clear": false
},
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": {
"owner": "cpp",
"fileLocation": "absolute",
"pattern": {
"regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
"file": 1,
"line": 2,
"column": 3,
"severity": 4,
"message": 5
}
}
},
{
"label": "Open Terminal.app",
"type": "shell",
"command": "osascript -e 'tell application \"Terminal\"\ndo script \"echo now VS Code is able to open Terminal.app\"\nend tell'",
"problemMatcher": [],
"group": "none"
}
]
}
这个是带注释的文件，但是可能由于编辑原因，直接复制这个可能会报错，需要自己手动更改，这里仅作注释参考
{
// Tasks in VS Code can be configured to run scripts and start processes
// so that many of these existing tools can be used from within VS Code
// without having to enter a command line or write new code.
// Workspace or folder specific tasks are configured from the tasks.json file in the .vscode folder for a workspace.
"version": "2.0.0",
"tasks": [
{
// The task's label used in the user interface.
// Terminal -> Run Task... 看到的名字
"label": "g++ compile",
// The task's type. For a custom task, this can either be shell or process.
// If shell is specified, the command is interpreted as a shell command (for example: bash, cmd, or PowerShell).
// If process is specified, the command is interpreted as a process to execute.
"type": "shell",// shell: 输入命令
// The actual command to execute.
// 因为g++已经在环境变量中了，所以我们这里写命令就行不用写g++的绝对路径
"command": "g++",
"args": [
"${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
},

3.launch.json
这个是无注释的文件
{
"version": "0.2.0",
"configurations": [
{
"type": "cppdbg",
"request": "launch",
"name": "C++ Debug",
"preLaunchTask": "g++ compile",
"program": "${fileDirname}/${fileBasenameNoExtension}.out",
"args": [],
"environment": [],
"cwd": "${workspaceFolder}",
"stopAtEntry": false,
"externalConsole": true,
"MIMode": "lldb"
}
]
}

{
// 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",
}
]
}
直接F5开始调试（如果你设置了多个launch可能需要在边栏Run哪里勾选相应的）
这里可能遇到一个问题，终端没有任何输出。这是什么原因呢？？？
GitHub issue｜VS Code因权限无法打开系统终端（大概1/2的地方）
回到tasks.json，快捷键⇧⌘P调出VSCode的命令窗口，搜索task，点击Tasks: Run Task，选择Open Terminal.app；给VS Code打开终端的权限。
