1.vscode-python代码调试
创建launch.json文件
{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "Python Debugger: My Current File","type": "debugpy","request": "launch","program": "${file}","cwd":"${workspaceFolder}/Path_to_FlashOcc/","console": "integratedTerminal"//"args": [// "${command:pickArgs}"//]}]
}
1.1 vscode中的${workspaceFolder}等变量
${workspaceFolder} :表示当前workspace文件夹路径，.vscode的绝对路经
${workspaceRootFolderName}:表示workspace的文件夹名，也即Test
${file}:文件自身的绝对路径，也即/home/Coding/Test/.vscode/tasks.json
${relativeFile}:文件在workspace中的路径，也即.vscode/tasks.json
${fileBasenameNoExtension}:当前文件的文件名，不带后缀，也即task
${fileBasename}:当前文件的文件名，tasks.json
${fileDirname}:文件所在的文件夹路径，也即/home/Coding/Test/.vscode
${fileExtname}:当前文件的后缀，也即.json
${lineNumber}:当前文件光标所在的行号
${env:PATH}:系统中的环境变量
1.2 vscode配置文件内容分析
1.2.1 launch.json
launch.json中存放运行或者调试可执行文件时的配置：
{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "g++ - Build and debug active file", // 名字随便取"type": "cppdbg","request": "launch",// program 指定调试那个可执行文件，需要绝对路径// ${fileDirname} 当前打开的文件所在的绝对路径，不包括文件名// ${fileBasenameNoExtension} 当前打开的文件的文件名，不包括路径和后缀名"program": "${fileDirname}/${fileBasenameNoExtension}.out", "args": [],"stopAtEntry": false,"cwd": "${fileDirname}", // cwd 字段来指定应用程序的当前工作目录，访问资源的时候从cwd指定的目录下访问。"environment": [],"externalConsole": false,"MIMode": "gdb","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true},{"description": "Set Disassembly Flavor to Intel","text": "-gdb-set disassembly-flavor intel","ignoreFailures": true}],"preLaunchTask": "C/C++: g++ build active file", // 在执行lanuch.json之前要做的任务"miDebuggerPath": "/bin/gdb" // 指定调试工具}]
}
其他参数解释：
${fileBasename} 当前打开的文件名+后缀名，不包括路径
${fileExtname} 当前打开的文件的后缀名
${cwd} the task runner's current working directory on startup
${workspaceFolder} .vscode所在目录的绝对路径
【注】文件名launch.json的前后不能有空格。如果你发现launch.json中明明正确的地方竟然都有红色的波浪线，很可能就是你的文件名launch.json有问题。
1.2.2 tasks.json
tasks.json中存放生成可执行文件的命令：
{"tasks": [{"type": "cppbuild","label": "C/C++: g++ build active file", // 任务名，在lanuch.json使用此任务名，从而执行此任务"command": "/bin/g++","args": ["-fdiagnostics-color=always","-g",// "${file}","${fileDirname}/*.cpp", // 编译当前打开的文件所在目录下的所有.cpp文件"-o","${fileDirname}/${fileBasenameNoExtension}.out" // 目标文件名],"options": {"cwd": "${fileDirname}"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true},"detail": "调试器生成的任务。"}],"version": "2.0.0"
}
1.2.3 c_cpp_properties.json
本小节使用cmake生成compile_commands.json，然后在c_cpp_properties.json中配置c_cpp_properties.json文件实现代码的跳转。具体见vscode使用compile_commands.json配置includePath环境.
这里的代码跳转指的是：光标移动到相应函数，然后按“ctrl+点击”就可以进行跳转。如果需要在debug的时候实现代码跳转，直接在launch.json中指定cmake生成的可执行文件就可以。
vscode中配置C/C++调试环境（launch.json和tasks.json）
windows下json文件：
launch.json

}
