Description

This PR fixes an error while calling Client.unload_extension() due to the extension containing a callback (component or modal) that uses a regex pattern (re.Pattern) listener.

Changes

• Edited Extension.drop() to allow for dropping re.Pattern listeners, which are stored in a different dict inside Client

Test Scenarios

The command /test-unload should run without errors with the extension's command /test-a unloaded. You may need to reload your Discord client (hotkey ^R) to refresh the list of commands.

test.py (main)

from interactions import Client, Intents, slash_command, SlashContext
bot = Client(intents=Intents.DEFAULT)

@slash_command(name="test-unload", description="Unload test extension")
async def unload_cmd(ctx: SlashContext):
  bot.unload_extension("test_ext")
  await ctx.send("Extension is unloaded")

bot.load_extension("test_ext")
bot.start("token")

test_ext.py (extension)

The command in this extension has two different component callbacks: a str one and a re.Pattern one.

from interactions import (
  Extension,
  slash_command,
  SlashContext,
  Button,
  ButtonStyle,
  component_callback,
  ComponentContext,
)
import re

regex_callback = re.compile(r"button-[0-9]+")

class TestExtension(Extension):
  @slash_command(name="test-a", description="Test command")
  async def test_cmd_a(self, ctx: SlashContext):
    btn_1 = Button(label="1", style=ButtonStyle.BLURPLE, custom_id="button-0001")
    btn_2 = Button(label="2", style=ButtonStyle.BLURPLE, custom_id="button-0002")
    btn_a = Button(label="A", style=ButtonStyle.BLURPLE, custom_id="button-a")
    await ctx.send(components=[btn_1, btn_2, btn_a])

  @component_callback(regex_callback)
  async def re_btn(self, ctx: ComponentContext):
    await ctx.send(f"Clicked button with id `{ctx.custom_id}`")

  @component_callback("button-a")
  async def str_btn(self, ctx: ComponentContext):
    await ctx.send(f"Clicked button with id `button-a`")
