VScode lanuch.json 预定变量

Variable substitution#

VS Code supports variable substitution inside strings in launch.json and has the following predefined variables:

• ${workspaceRoot} - the path of the folder opened in VS Code
• ${workspaceRootFolderName} - the name of the folder opened in VS Code without any slashes (/)
• ${file} - the current opened file
• ${relativeFile} - the current opened file relative to workspaceRoot
• ${fileBasename} - the current opened file's basename
• ${fileBasenameNoExtension} - the current opened file's basename with no file extension
• ${fileDirname} - the current opened file's dirname
• ${fileExtname} - the current opened file's extension
• ${cwd} - the task runner's current working directory on startup
• ${lineNumber} - the current selected line number in the active file

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

{
    "type": "node",
    "request": "launch",
    "name": "Launch Program",
    "program": "${workspaceRoot}/app.js",
    "cwd": "${workspaceRoot}",
    "args": [ "${env:USERNAME}" ]
}

 

You can reference VS Code settings and commands using the following syntax:

• ${config:Name} - example: ${config:editor.fontSize}
• ${command:CommandID} - example: ${command:explorer.newFolder}
