在.vscode文件夹下建立launch.json

例子1：调试python

来自
https://github.com/chunleili/tiPBD/tree/amg

{"version": "0.2.0","configurations": [{"name": "hpbd 5 5","type": "python","request": "launch","program": "engine/volumetric/arap_multigrid.py","console": "integratedTerminal","args": ["--fine_iterations", "5","--coarse_iterations", "5","--solver_type", "Jacobian","--multigrid_type", "HPBD"]},]
}

逐行解释：
name是显示在侧边栏的名字，例如

program是要调试的程序

console是console打开的类型，分为内部（vscode内）和外部（额外弹出个终端模拟器）

args是调试传入参数，注意对应于命令行的每个空格都要单独分一个词。

例子2：调试c++

参考
https://github.com/chunleili/fast_mass_spring

{"version": "0.2.0","configurations": [{"name": "(msvc) Launch","type": "cppvsdbg","request": "launch",// Resolved by CMake Tools:"program": "${workspaceFolder}/fast_mass_spring/main.exe","args": [],"stopAtEntry": true,"cwd": "${workspaceFolder}/fast_mass_spring","environment": [{"name": "PATH","value": "${env:PATH}:${command:cmake.getLaunchTargetDirectory}"}],"console": "externalTerminal"}]
}

这里额外增加了几个

cwd是设定当前目录
stopAtEntry是是否在程序第一句暂停
environment是设定环境变量，这里将${command:cmake.getLaunchTargetDirectory}追加到PATH最后

GUI的使用

如图，
