Version 3.1

Changes:

• Added a @checks.is_owner check which raises a UserNotOwner exception
• Added a @checks.not_blacklisted check which raises a UserBlacklisted exception
• Using checks instead of same code for every command
• Various code cleanup

What's new is mostly the ability to use checks instead of code for checking if, for example, the user trying to execute the command is not an owner.

Before: (Blacklist check, had to be copied on every command)

@cog_ext.cog_slash(
  name="ping",
  description="Check if the bot is alive.",
)
async def ping(self, context: SlashContext):
  with open("blacklist.json") as file:
    blacklist = json.load(file)
  if context.author.id in blacklist["ids"]:
    return
  # Rest of the code

Now:

@cog_ext.cog_slash(
  name="ping",
  description="Check if the bot is alive.",
)
@checks.not_blacklisted() # Here is the difference
async def ping(self, context: SlashContext):
  # Rest of the code
