如何理解VSCode tasks.json中的替换变量${workspaceFolder}的含义？

本文共计675个文字，预计阅读时间需要3分钟。

在编写任务配置时，使用一组预定义的常用变量通常很有用。VS Code 支持在 tasks.json 文件中的字符串内部进行变量替换，并提供了以下预定义变量：${workspaceFolder}。

When authoring tasks configurations, it is often useful to have a set of predefined common variables. VS Code supports variable substitution inside strings in the tasks.json file and has the following predefined variables:

• ${workspaceFolder} the path of the workspace folder that contains the tasks.json file
• ${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 the workspace folder containing the file
• ${fileBasename} the current opened file's basename
• ${fileBasenameNoExtension} the current opened file's basename without the 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} (for example, ${env:PATH}). Be sure to match the environment variable name's casing, for example ${env:Path} on Windows.

Below is an example of a custom task configuration that passes the current opened file to the TypeScript compiler.

{ "taskName": "TypeScript compile", "type": "shell", "command": "tsc ${file}", "problemMatcher": [ "$tsc" ] }

部分翻译：（来自互联网）

${workspaceRoot} 当前打开的文件夹的绝对路径+文件夹的名字

${workspaceRootFolderName} 当前打开的文件夹的名字

${file}当前打开正在编辑的文件名，包括绝对路径，文件名，文件后缀名

${relativeFile}从当前打开的文件夹到当前打开的文件的路径

如 当前打开的是test文件夹，当前的打开的是main.c，并有test / first / second / main.c

那么此变量代表的是 first / second / main.c

${fileBasename} 当前打开的文件名+后缀名，不包括路径

${fileBasenameNoExtension} 当前打开的文件的文件名，不包括路径和后缀名

${fileDirname} 当前打开的文件所在的绝对路径，不包括文件名

${fileExtname} 当前打开的文件的后缀名

${cwd} the task runner's current working directory on startup

不知道怎么描述，这是原文解释，

跟 cmd 里面的 cwd 是一样的

${lineNumber} 当前打开的文件，光标所在的行数
