- ${fileWorkspaceFolder} - the current opened file's workspace folder
- ${relativeFile} - the current opened file relative to
workspaceFolder - ${relativeFileDirname} - the current opened file's dirname relative to
workspaceFolder - ${fileBasename} - the current opened file's basename
- ${fileBasenameNoExtension} - the current opened file's basename with no file extension
- ${fileExtname} - the current opened file's extension
- ${fileDirname} - the current opened file's folder path
- ${fileDirnameBasename} - the current opened file's folder name
- ${cwd} - the task runner's current working directory upon the startup of VS Code
- ${lineNumber} - the current selected line number in the active file
- ${selectedText} - the current selected text in the active file

${workspaceRoot} 已经不用了？ 改用${workspaceFolder}？
ts 在vscode下debug.
1. tsconfig.json 问题配置sourceMap选项, chrome和node能根据编译出的js 和map 文件，对应到原来ts文件.
{
"compilerOptions": {
"target": "es6",
"module": "es6",
"outDir": "../../bin/tsc/layaAir",
....
"sourceMap":true,
.....
}
}
2. .vscode/lauch.json的配置, 并且添加sourceMapPathOverrides 路径映射, 打开编译出的map file,
看到路径开关是什么，以它作为key, 工程中ts路径为value

},3. 缓存问题, userDataDir会缓存js代码，有时发现编译后代码还是旧的，可以删除.vscode/chrome目录，再调试.真系丢累老木
