discord.py 2.0+ slash command info and examples

00-deprecation.md

This gist has now been 'deprecated' and has moved...

... to my blog style space for easier contribution by third parties and to provide what I believe to be an easier reading experience. Please field all enquiries and issues to the source repository.

Can't link the line for some reason but line 7 to 10 in extension_with_group-py should be changed to the following:

class MyCog(commands.GroupCog, group_name="parent"):
  def __init__(self, bot: commands.Bot) -> None:
    self.bot = bot

Agreed, done.
I have also updated to show an actual hybrid commands example.

thank you for this.

The term hybrid is a new feature according to https://discordapp.com/channels/336642139381301249/381965829857738772/965731673717223495 that enables ext.commands to be re-used as slash commands.

You use the term hybrid but I don;t see you using @commands.hybrid_command() or @commands.hybrid_group()

Delayed, but this has been done.

Can we have same example but without cogs? Please ^^'

I also have this above.

How would I describe option in hybrid commands? With app_commands.describe? Or some other way?

Thank you, this gist is very helpful

I fail to understand how the bot is run, I cant see anywhere a bot.run(token=...) nor how to use this async def setup mind enlighting me please ? :D

@Tyskiep99 These are Cogs, and are meant to be used with a separate python script for the "main" bot, which will "load" or "import" these cogs.

the bot.run and setup() methods are defined elsewhere, and don't affect the way these cogs are written.

Yes I noticed afterward, I had deleted that comment, sorry about that, I have seen the https://discordpy.readthedocs.io/en/stable/migrating.html#asyncio-event-loop-changes thanks for the reply !

I've got one more question, please, I have trouble with the Greedy param from @AbstractUmbra example of sync command, it seems it doenst work:

discord.ext.commands.errors.ExtensionFailed: Extension 'eqdkp_ng.cogs.admin' raised an error: TypeError: unhashable type: 'Greedy'

my import in the cog is as follow:

import discord
from discord.ext import commands
# and the params:
guilds: commands.Greedy[discord.Object]

It is an annotation, not an assignment.

You have =, you should have :

sorry that was a typo, it is a : I also tried with guilds: commands.Greedy[discord.Guild] but same effect, I use it in a @app_commands.command() in the cog maybe that is why? Is it only reserved to old bot.command ?

Yes, app commands have no capability of consumption arguments. The sync command presented is designed as a Message command only.

Thanks a lot for the information.
Altho I have another question sorry to bother but I cant any information anywhere about it,
I have an app command using my models from db to load items for a converter (event: Enum('Events', Event.get_event_dict_enum_from_db())).
And I have another command to add new entry in the db. I dont use bot.tree.copy_global_to (should I?) I also dont use bot.tree.sync anywhere (yet).
The issue I am facing is when I add a new entry for the converter in the db, and after issuing the !sync or !sync ~ command, the list is not updated. I tried to put a .sync after the entry is added in the adding command but without success too.
How would you tackle this? Is it even possible? (the command converter list get updated after a reboot of the bot and a sync) - the bot is intended to be used only within one guild

This would be better discussed in the discord.py server as I'm not fully understanding what you're asking.

You do need to sync your slash commands, but read over this first.

Are we supposed to call setup ourselves via asyncio? It's not really clear. I'm coming from the old and easy on_message() and I'm totally lost.

and how do you load em to use em??? i cant load em in any wise idk

Hello Umbra, want to suggest some changes for #file-9-subclassing_group-py...

- # this a app command group
+ # this is an App command group
- # you can nest these up 1: 
- # `/group group` = VALID
+ # Valid combinations:
+ # /group subcommand (up to 25)
+ # /group subcommand group
+ # /group subcommand group subcommand (up to 25)
- # /group group group` = INVALID
- # etc... all invalid.

# this example shows one way to do this, subclassing
# the other is constructing an instance of app_commands.Group()
# that one is shown in "free_function_commands-py"

import discord
from discord import app_commands

- # the @app_commands.guilds and others (including checks) can be used above the class
+ # checks like @app_commands.guilds and @app_commands.default_permissions can be used above the class
- # these will apply to ALL subcommand, subcommands cannot have invidual perms!
+ # these will apply to all subcommands, subcommands cannot have individual perms.
@app_commands.guild_only()
class Group(app_commands.Group):

Done.

I know this is old, but do you have anything to add an input in the command, like /ban user:<user> reason:[reason] with <> being required and [] is optional?

You can give it a default value of something like None and check that in your function accordingly.

Im actually having trouble with this too haha! How do you read in "the rest of the message" my old way was to just

*args

But now i cant do that because of typing, *args: tuple doesn't work, nor does str, I'm at my wits end!

@KenwoodFox

The reason for this is not discord.py related. Slash commands themselves have no concept of "consumption args" or varargs like ext.commands implements.

You simply cannot do this this way.

The recommend way is to take a str input and then .split() it with a clear separator, or have N many arguments.
Sad but this is the most recommended ways of doing it.

That makes it really hard for users who don't usually have concepts of wrapping strings with " or using other deliminaters than space :c i might just not migrate these commands that expect full sentence strings until something can be figured out.

Hyperlink is outdated for CommandTree.copy_global_to at Syncing gotchas.

Thanks! Resolved.

can anyone tell me why i am unable to use slash commands while dming my bot? i have them in a tree, and sync without specifying any guilds, i.e. globally, i assumed this would sync to dms as well. but it just won't work. I know it is possible in theory to dm slash-commands, but i just see no documentation on how to achieve this with discord.py...

show me the code @D-Stacks
