Methods
class discord.Cog(*args: Any, **kwargs: Any)[исходный код]

The base class that all cogs must inherit from.

A cog is a collection of commands, listeners, and optional state to help group commands together. More information on them can be found on the Cogs page.

When inheriting from this class, the options shown in CogMeta are equally valid here.

get_commands()[исходный код]
Результат:

A list of ApplicationCommands that are defined inside this cog.

Примечание

This does not include subcommands.

Тип результата:

list[ApplicationCommand]

property qualified_name: str

Returns the cog’s specified name, not the class name.

property description: str

Returns the cog’s description, typically the cleaned docstring.

walk_commands()[исходный код]

An iterator that recursively walks through this cog’s commands and subcommands.

Yields:

Union[Command, Group] – A command or group from the cog.

get_listeners()[исходный код]

Returns a list of (name, function) listener pairs that are defined in this cog.

Результат:

The listeners defined in this cog.

Тип результата:

list[tuple[str, Callable[..., Any]]]

classmethod listener(name=..., once=False)[исходный код]

A decorator that marks a function as a listener.

This is the cog equivalent of Bot.listen().

Параметры:

  • name (str) – The name of the event being listened to. If not provided, it defaults to the function’s name.

  • once (bool) – If this listener should only be called once after each cog load. Defaults to false.

Исключение:

TypeError – The function is not a coroutine function or a string was not passed as the name.

Тип результата:

Callable[[TypeVar(FuncT, bound= Callable[..., Any])], TypeVar(FuncT, bound= Callable[..., Any])]

has_error_handler()[исходный код]

Checks whether the cog has an error handler.

Добавлено в версии 1.7.

Тип результата:

bool

cog_unload()[исходный код]

A special method that is called when the cog gets removed.

This function cannot be a coroutine. It must be a regular function.

Subclasses must replace this if they want special unloading behaviour.

Тип результата:

None

bot_check_once(ctx)[исходный код]

A special method that registers as a Bot.check_once() check.

This function can be a coroutine and must take a sole parameter, ctx, to represent the Context or ApplicationContext.

Параметры:

ctx (ApplicationContext) – The invocation context.

Тип результата:

bool

bot_check(ctx)[исходный код]

A special method that registers as a Bot.check() check.

This function can be a coroutine and must take a sole parameter, ctx, to represent the Context or ApplicationContext.

Параметры:

ctx (ApplicationContext) – The invocation context.

Тип результата:

bool

cog_check(ctx)[исходный код]

A special method that registers as a check() for every command and subcommand in this cog.

This function can be a coroutine and must take a sole parameter, ctx, to represent the Context or ApplicationContext.

Параметры:

ctx (ApplicationContext) – The invocation context.

Тип результата:

bool

await cog_command_error(ctx, error)[исходный код]

A special method that is called whenever an error is dispatched inside this cog.

This is similar to on_command_error() except only applying to the commands inside this cog.

This must be a coroutine.

Параметры:
Тип результата:

None

await cog_before_invoke(ctx)[исходный код]

A special method that acts as a cog local pre-invoke hook.

This is similar to ApplicationCommand.before_invoke().

This must be a coroutine.

Параметры:

ctx (ApplicationContext) – The invocation context.

Тип результата:

None

await cog_after_invoke(ctx)[исходный код]

A special method that acts as a cog local post-invoke hook.

This is similar to ApplicationCommand.after_invoke().

This must be a coroutine.

Параметры:

ctx (ApplicationContext) – The invocation context.

Тип результата:

None

Attributes
class discord.CogMeta(*args, **kwargs)[исходный код]

A metaclass for defining a cog.

Note that you should probably not use this directly. It is exposed purely for documentation purposes along with making custom metaclasses to intermix with other metaclasses such as the abc.ABCMeta metaclass.

For example, to create an abstract cog mixin class, the following would be done.

import abc

class CogABCMeta(discord.CogMeta, abc.ABCMeta):
    pass

class SomeMixin(metaclass=abc.ABCMeta):
    pass

class SomeCogMixin(SomeMixin, discord.Cog, metaclass=CogABCMeta):
    pass

Примечание

When passing an attribute of a metaclass that is documented below, note that you must pass it as a keyword-only argument to the class creation like the following example:

class MyCog(discord.Cog, name='My Cog'):
    pass
name

The cog name. By default, it is the name of the class with no modification.

Type:

str

description

The cog description. By default, it is the cleaned docstring of the class.

Добавлено в версии 1.6.

Type:

str

command_attrs

A list of attributes to apply to every command inside this cog. The dictionary is passed into the Command options at __init__. If you specify attributes inside the command attribute in the class, it will override the one specified inside this attribute. For example:

class MyCog(discord.Cog, command_attrs=dict(hidden=True)):
    @discord.slash_command()
    async def foo(self, ctx):
        pass # hidden -> True

    @discord.slash_command(hidden=False)
    async def bar(self, ctx):
        pass # hidden -> False
Type:

dict

guild_ids

A shortcut to command_attrs, what guild_ids should all application commands have in the cog. You can override this by setting guild_ids per command.

Добавлено в версии 2.0.

Type:

Optional[List[int]]
