Visual Studio Code 中 launch.json 的通用变量 [英] Common variables for launch.json in Visual Studio Code

问题描述

我已经看到 Visual Studio Code 的 launch.json 如何访问 ${workspaceFolder}.它是否也可以访问其他公共变量?我想访问当前用户的 AppData 文件夹，以便我可以这样做:

I have seen how launch.json for Visual Studio Code has access to ${workspaceFolder}. Does it also have access to other common variables? I would like to have access to the current user's AppData folder so I can do:

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

而不是将其硬编码为:

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

推荐答案

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}.

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

VS Code 支持 launch.json 中字符串内的变量替换，与 tasks.json 相同.

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} 当前打开文件的基名
• ${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

• ${workspaceFolder} the path of the folder opened in VS Code
• ${file} the current opened file
• ${relativeFile} the current opened file relative to workspaceRoot
• ${fileBasename} the current opened file's basename
• ${fileDirname} the current opened file's dirname
• ${fileExtname} the current opened file's extension
• ${cwd} the task runner's current working directory on startup

您还可以通过 ${env:Name} 引用环境变量(例如${env:PATH}).确保匹配环境变量名称的大小写，例如 env:Path 在 Windows 上.

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.
