Arguments for Commands in VS Code

Question

So obviously there are arguments for commands and registering a command like

vscode.commands.registerCommand("bla", (arg1: any, arg2: any) => {});

brings arg1 with a strange object containing only one key and that's context; an object holding some information about - you guessed it - the context.

There is also no way for the user to specify arguments. Not through the command palette and not for keybindings.

So are those arguments only for internal stuff or are they supposed to be used by an extension developer?

Answer 1

In keybindings.json you can specify arguments as such:

{
    "command": "workbench.action.tasks.runTask",
    "key": "alt+d",
    "args": "docker"
}

To access keybindings.json open View > Command Palette and type/choose Preferences: Open Keyboard Shortcuts (JSON). You may also want to assign a keyboard shortcut to this command.
