visual-studio-code - Visual Studio Code 中 launch.json 的常用变量

Question

我看到了launch.json对于 Visual Studio Code 可以访问 ${workspaceFolder} .它是否也可以访问其他公共(public)变量？我想访问当前用户的 AppData 文件夹，所以我可以这样做:

"program": "${appData}\\Roaming\\npm\\node_modules\\gulp\\bin\\gulp.js"

而不是硬编码为:

"program": "C:\\Users\\jdoe\\AppData\\Roaming\\npm\\node_modules\\gulp\\bin\\gulp.js"

launch.json 中的变量替换支持环境变量。对于您的用例，您可以使用 ${env:AppData} .

VS Code supports variable substitution inside strings in launch.json the same way as for tasks.json.

${workspaceFolder} VS Code中打开的文件夹路径

${file}当前打开的文件

${relativeFile}当前打开的文件相对于 workspaceRoot

${fileBasename}当前打开文件的基本名称

${fileDirname}当前打开文件的目录名

${fileExtname}当前打开文件的扩展名

${cwd}启动时任务运行器的当前工作目录

You can also reference environment variables through ${env:Name} (e.g. ${env:PATH}). Be sure to match the environment variable name's casing, for example env:Path on Windows.
