Common variables for launch.json in Visual Studio Code

Question

I saw how start.json for Visual Studio Code has access to "$ {workspaceRoot}. Does it also have access to other shared variables? I would like to have access to the user's current appdata folder so that I can:

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

instead of hard coding:

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

Variable substitution in launch.json supports environment variables. For your use case you can use ${env.AppData}.

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

• $ {workspaceRoot} path to the folder opened in VS Code
• $ {file} current open file
• ${relativeFile} workspaceRoot
• ${fileBasename}
• ${fileDirname} dirname
• ${_}
• ${cwd}

${env.Name} (, ${Env.PATH}). , env.Path Windows.
