How to undo the whole chain?

[saveman71]

Hello! Thanks for the great package.

Given the following:

  {
     "keys": ["ctrl+shift+up"],
     "command": "chain",
     "args": {
       "commands": [
         ["swap_line_up"],
         ["reindent", {"single_line": true}]
       ],
     },
   },
  {
    "keys": ["ctrl+shift+down"],
    "command": "chain",
    "args": {
      "commands": [
        ["swap_line_down"],
        ["reindent", {"single_line": true}]
      ],
    },
  },

I'd love sublime to understand that one "shortcut" should be undoable "as a whole action". Currently to undo the whole chain, i have to hit ctrl+z multiple times (sometimes only once if the "reindent" action didn't do anything.

Is anyone aware of any solution to make Sublime Text understand I want to wrap this whole "chain" (and whatever it does to the buffer) as one single atomic action?

Had the same problem. A discussion in the ST Discord revealed that this can be fixed by converting the plugin from WindowCommand to TextCommand:

import sublime_plugin

class chain(sublime_plugin.TextCommand):
    def run(self, edit, commands):
        for command in commands:
            self.view.window().run_command(*command)

You can make a small local plugin, or use PackageResourceViewer to unpack CoC and edit it. If this works well, this change should probably be made in CoC so that everyone can benefit, but I'm still evaluating this.

Also, judging by the source, Multicommand uses TextCommand and should be undoable all at once. Haven't tried it yet.

Yaay, I had these shortcuts commented for 1 year and a half now and finally I can use it! Thanks!
