Is there a way to find all the loaded and unloaded cogs in discord.py-rewrite

问题

I have a lot of cogs for my bot, but i load and unload them using commands

Still I get confused and load/unload a cog again-and-again

I wonder is there a way to check all the loaded and unloaded cogs using commands.(Other than the default help command)

回答1:

Looking at discord.py documentation, if you try to load a cog that is already loaded, it will raise a discord.ext.commands.ExtensionAlreadyLoaded exception. Using this error, you could do this:

from discord import commands

bot = commands.Bot(command_prefix="!")

@bot.command()
async def check_cogs(ctx, cog_name):
    try:
        bot.load_extension(f"cogs.{cog_name}")
    except commands.ExtensionAlreadyLoaded:
        await ctx.send("Cog is loaded")
    except commands.ExtensionNotFound:
        await ctx.send("Cog not found")
    else:
        await ctx.send("Cog is unloaded")
        bot.unload_extension(f"cogs.{cog_name}")

PS: your cogs will need to be in a cogs folder for this code to work.
