If a command or a group raised a CommandError derived exception it
would be wrapped into CommandInvokeError. This fixes this case so it
raises the original exception instead.
This is to support people who want to clean up some external resource
that the extension is maintaining outside of a cog, where __unload
should be used instead.
The callable is the antipode of 'setup' and takes the same sole
parameter, the bot, after all commands, events, and cogs have been
unloaded.
Fixes#405.
Sometimes the bot would keep waiting for chunks that somehow finished
before getting to the `wait` call. This is more so a temporary fix
rather than a fully correct one.
Help formatter was not checking global bot-level checks, resulting in
showing commands a user did not have permission for with
show_check_failure disabled.
This is to allow people to set temporary local variables by injecting
them directly into the context via some decorator or some other
mechanism. Contexts are not kept alive long enough to warrant being
slotted.
Allow for easier use when trying to "reuse" the same discord.Embed
object by providing new methods such as Embed.clear_fields,
Embed.set_field_at, and allowing you to set things to Embed.Empty to
clear out an attribute.
For ease of use, things are automatically casted to ``str`` to prevent
the user from having HTTP 400 errors if they forgot to do so. The new
embed builder also supports "fluent-style" interface to allow you to
chain methods in a single line if necessary.
Certain parameters were removed since they were ignored by Discord
anyway such as `width` and `height` in Embed.set_image and
Embed.set_thumbnail.
Discord can sometimes send integer 0 as the emoji id instead of
null to signify a non-custom emoji, which was causing a crash due
to a 'is not None' check assuming the reaction was for an emoji
with id 0. Probably a discord bug, but preferable to handle here
rather than crash users.
This changes the event signature to be (reaction, user) instead of
(message, reaction, user) since the reaction data class already has
the message being reacted to as a member.
The name was shortened from on_message_reaction_ to on_reaction_ since
the message prefix was deemed redundant.
Reaction objects with custom Emoji are partial. If we know of this Emoji
(can find it on this client) then inject it. Otherwise, leave it as a
hollow Emoji. We can still react with a hollow Emoji, but can't get other
metadata about it.
Reactions can be be standard emojis, or custom server emojis.
