Support Variable Substitution for Keyboard Binding Command Arguments

[ericdrobinson]

Issue Type: Feature Request

I am working on a debugger extension for VSCode that provides a command to run a configurable script in a configurable host. Users would very much benefit from the ability to specify the same variables that they can in launch.json in the Command Arguments for a given keyboard binding that triggers the "Run Target Script" command.

An example might look like:

{
    "key": "cmd+alt+j",
    "command": "extension.extendscript-debug.evalInHost",
    "args": {
        "hostAppSpecifier": "premierepro-22",
        "engineName": "NewWorld",
        "filePath": "${file}",    // <-- Variable Substitution!
        "debugLevel": 0,
    },
}

I tried

{
    "key": "ctrl+q c",
    "command": "type",
    "when": "editorTextFocus",
    "args": {
        "text": "${fileDirname}/${selectedText}"
    }
}

and it does not substitute the variables.

I really need this feature. Any plans to add it?

Currently seems like the substitution is done by the command reciever like in workbench.action.findInFiles, so other commands like editor.action.startFindReplaceAction dont. See #151311.

It would be much simpler if the substitution happened before sending the arguments like suggested in this issue.

@alexdima I would be willing to contribute a PR if you can point out the relevant code.
