EventListener returning command doesn't seem to work?

#1

According to the docs, on_text_command should allow you to alter or run a different command, but if I return anything, the command just gets eaten. I think this should scroll if it hit 'ctrl+UP`. It prints out “scroll” but does not scroll the window. Why doesn’t this work?

class EventTrap(sublime_plugin.EventListener):
	def on_text_command(self, view, command, args):
		if command == 'scroll_lines':
			print("scroll")
			return (command, args)

on_text_command is also run for commands overridden by on_text_command. As such the code you’ve provided leads to an infinite loop. In order to not lock up the whole application this is detected and the command is ignored.

That makes sense.

It would be nice to log a msg, rather than silently eating the event.
