class lightbulb.context.base.ApplicationContext(app: app_.BotApp, event: hikari.InteractionCreateEvent, command: commands.base.ApplicationCommand)[source]#

get_channel() → GuildChannel | Snowflake | None[source]#: The channel object for the context’s channel ID.

async respond(*args: Any, delete_after: float | int | None = None, **kwargs: Any) → ResponseProxy[source]#

Create a response for this context. The first time this method is called, the initial interaction response will be created by calling create_initial_response with the response type set to MESSAGE_CREATE if not otherwise specified.

Subsequent calls will instead create followup responses to the interaction by calling execute.

Parameters:

*args (Any) – Positional arguments passed to CommandInteraction.create_initial_response or CommandInteraction.execute.
delete_after (Union[int, float, None]) – The number of seconds to wait before deleting this response.
**kwargs – Keyword arguments passed to CommandInteraction.create_initial_response or CommandInteraction.execute.

Returns:

Proxy wrapping the response of the respond call.

Return type:

ResponseProxy

New in version 2.2.0: delete_after kwarg.

async respond_with_modal(title: str, custom_id: str, component: hikari.UndefinedOr[special_endpoints.ComponentBuilder] = UNDEFINED, components: hikari.UndefinedOr[t.Sequence[special_endpoints.ComponentBuilder]] = UNDEFINED) → None[source]#

Create a modal response to this context.

Parameters:

title (str) – The title that will show up in the modal.
custom_id (str) – Developer set custom ID used for identifying interactions with this modal.
component (UndefinedOr[hikari.api.special_endpoints.ComponentBuilder]) – A component builder to send in this modal.
components (UndefinedOr[Sequence[hikari.api.special_endpoints.ComponentBuilder]]) – A sequence of component builders to send in this modal.

Returns:

None

Raises:

ValueError – If both component and components are specified or if neither are specified.

class lightbulb.context.base.OptionsProxy(options: Dict[str, Any])[source]#

Proxy for the options that the command was invoked with allowing access using dot notation as well as dictionary lookup.

Parameters:: options (Dict[str, Any]) – Options to act as a proxy for.

items() → ItemsView[str, Any][source]#

Iterates through the options and returns a series of key:value pairs.

Returns:

The options items. This: is functionally similar to a list of tuples, where for each tuple, the key is the option name, and the value is the option value.

Return type:

ItemsView[str, Any]

class lightbulb.context.base.ResponseProxy(message: Message | None = None, fetcher: Callable[[], Coroutine[Any, Any, Message]] | None = None, editor: Callable[[ResponseProxy], Coroutine[Any, Any, Message]] | None = None, deleteable: bool = True)[source]#

Proxy for context responses. Allows fetching of the message created from the response lazily instead of a follow-up request being made immediately.

async delete() → None[source]#

Deletes the message that this object is proxying.

Returns:: None
Raises:: UnsupportedResponseOperation – This response cannot be deleted (for some ephemeral interaction responses).

async edit(*args: Any, **kwargs: Any) → Message[source]#

Edits the message that this object is proxying. Shortcut for hikari.messages.Message.edit.

Parameters:

*args – Args passed in to hikari.messages.Message.edit
**kwargs – Kwargs passed in to hikari.messages.Message.edit

Returns:

New message after edit.

Return type:

Message

Raises:

UnsupportedResponseOperation – This response cannot be edited (for ephemeral interaction followup responses).

async message() → Message[source]#

Fetches and/or returns the created message from the context response.

Returns:: The response’s created message.
Return type:: Message

Note

This object is awaitable (since version 2.2.2), hence the following is also valid.

# Where 'resp' is an instance of ResponseProxy

# Calling this method
message = await resp.message()
# Awaiting the object itself
message = await resp

Prefix Context#

class lightbulb.context.prefix.PrefixContext(app: app_.BotApp, event: hikari.MessageCreateEvent, command: t.Optional[commands.prefix.PrefixCommand], invoked_with: str, prefix: str)[source]#

Bases: Context

Parameters:

app (BotApp) – The BotApp instance that the context is linked to.
event (MessageCreateEvent) – The event to create the context from.
command (Optional[PrefixCommand]) – The command that the context is for, or None if no command could be resolved.
invoked_with (str) – The name or alias that the command was invoked with.
prefix (str) – The prefix that was used in this context.

get_channel() → GuildChannel | Snowflake | None[source]#: The channel object for the context’s channel ID.

async respond(*args: Any, delete_after: float | int | None = None, **kwargs: Any) → ResponseProxy[source]#

Create a response for this context. This method directly calls respond. You should note that it is not possible to send ephemeral messages as responses to prefix commands. All message flags will be removed before the call to respond.

Parameters:

*args (Any) – Positional arguments passed to respond.
delete_after (Union[int, float, None]) – The number of seconds to wait before deleting this response.
**kwargs (Any) – Keyword arguments passed to respond.

Returns:

The created message object.

Return type:

Message

New in version 2.2.0: delete_after kwarg.

Method only preserved for API consistency. If you attempt to call this method for a prefix command, a NotImplementedError will always be raised.

Raises:: NotImplementedError – Always
