How work this example?

• edit somewhere_dir/something.txt show filename in console from the task labeled "show_filename".

• edit (workspace_root)/js/something.js run JavaScript on node command in the task labeled "run_js".

• edit (workspace_root)/index.html run the task labeled "show_filename" to open index.html in browser.(in Windows)

• edit somewhere_dir/index-1234.html

• edit somewhere_dir/index-256.html open index-{number}.html in browser (in Windows)

How to get part of changed file

1. define in "inputs" section like the following.

    "inputs": [
        {
            "id": "inputId",
            "type": "command",
            "command": "watch-run.getFilename",
            "args" : "run_js"
        }
    ]

• the "args" is the same as the label of task.

2. use ${input:inputId} in command of task to get the path.

Command	Value
getFilename	c:\work\temp\file.ext
getDirname	c:\work\temp
getBasename	file.ext
