Slash Commands
==============
Slash Commands are currently supported in enhanced-discord.py using a system on top of ext.commands.
This system is very simple to use, and can be enabled via :attr:`.Bot.slash_commands` globally,
or only for specific commands via :attr:`.Command.slash_command`.
There is also the parameter ``slash_command_guilds`` which can be passed to either :class:`.Bot` or the command
decorator in order to only upload the commands as guild commands to these specific guild IDs, however this
should only be used for testing or small (<10 guilds) bots.
If you want to add option descriptions to your commands, you should use :class:`.Option`
For troubleshooting, see the :ref:`FAQ <ext_commands_slash_command_troubleshooting>`
.. admonition:: Slash Command Only
For parts of the docs specific to slash commands, look for this box!

.. _ext_commands_slash_command_troubleshooting:
You need to invite your bot with the ``application.commands`` scope on each guild and
you need the :attr:`Permissions.use_slash_commands` permission in order to see slash commands.
.. image:: /images/discord_oauth2_slash_scope.png
:alt: The scopes checkbox with "bot" and "applications.commands" ticked.
Global slash commands (created by not specifying :attr:`~ext.commands.Bot.slash_command_guilds`) will also take up an
hour to refresh on discord's end, so it is recommended to set :attr:`~ext.commands.Bot.slash_command_guilds` for development.
If none of this works, make sure you are actually running enhanced-discord.py by doing ``print(bot.slash_commands)``
My bot won't start after enabling slash commands!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This means some of your command metadata is invalid for slash commands.
Make sure your command names and option names are lowercase, and they have to match the regex ``^[\w-]{1,32}$``
If you cannot figure out the problem, you should disable slash commands globally (:attr:`~ext.commands.Bot.slash_commands`\=False)
then go through commands, enabling them specifically with :attr:`~.commands.Command.slash_command`\=True until it
errors, then you can debug the problem with that command specifically.
