Version 4200, io_panel with on_change method

[weiwang2021]

It is great to have io_panel，can the associated inputbox have the abilities of input_panel. For example, can I bind a on_change method to the inputbox in addition to on_input.

create_io_panel() returns two ordinary sublime.View instances both of which ordinary sublime_plugin.EventListener classes can be created for to handle all sorts of events.

As view.element() returns None for io panels’ input_views, a view specific setting (e.g. is_input_widget) may be required to identify input panel and handle specific events.

Here’s a minimal example with auto completion enabled.

from __future__ import annotations
import sublime
import sublime_plugin


class CreateIoPanel(sublime_plugin.WindowCommand):

    def run(self):
        self.out_view, self.input_view = self.window.create_io_panel("my_panel", on_input=self.on_input)
        # configure output view
        settings = self.out_view.settings()
        settings.set("gutter", False)
        # configure input view
        settings = self.input_view.settings()
        settings.set("is_input_widget", True)
        settings.set("auto_complete", True)
        settings.set("auto_complete_disabled", False)
        settings.set("auto_complete_selector", "source, text")

    def on_input(self, input):
        self.out_view.run_command("insert", {"characters": input + "\n"})


class IoPanelEventListener(sublime_plugin.EventListener):

    def on_modified(self, view: sublime.View):
        # only handle input_widget events
        if not view.settings().get("is_input_widget"):
            return

        print(f"View {view} changed")

    def on_query_completions(self, view: sublime.View, prefix: str, locations: list[sublime.Point]):
        # only handle input_widget events
        if not view.settings().get("is_input_widget"):
            return

        print(f"View {view} changed")
