Binary logs are no longer stored as a single message with a list of
strings and int64s ("body", "user_name", "user_id", "when"), but a
message with sub-messages (IM_MESSAGE_RECEIVED) verbatim saved.
This has the main benefit of preserving message formatting (coloring,
bold, italics, etc).
Chat messages can now be formatted with colors in addition to varying
faces with "color_start," "color_length," and "color" slots in
IM_MESSAGE_RECEIVED.
Now addons can format messages with new slots accepted by
IM_MESSAGE_RECEIVED: "face_start," "face_length," and "face".
The first two deal with the position of the face-change by character
offset in the string, and the last being the face flag affected.
Now, per each account, there is a read-only chat view associated with
it, accessible through its item in the conversations list. This can be
used to place system messages, MOTDs, insignificant errors, etc.
Protocols can send text to this buffer by specifying no "chat_id" in
an IM_MESSAGE_RECEIVED message.
Some chat protocol messages' names have been changed to more fitting or
consistent names― e.g., "IM_AVATAR_SET" to "IM_USER_AVATAR_SET", or
"IM_CONTACT_LIST_*" to "IM_ROSTER_*" (to agree with Cardie's usage of
the word).
The API version has been bumped― for the forseeable future (at least
several months, I promise!) no compatibility-breaking changes will be
introduced. Until then, any new feautures or message slots will be
additive and optional.
Currently, add-ons are disconnected when ChatProtocol::Shutdown() is
called, which the add-on can do by itself― but there is no standard way
for add-ons to notify the app about their Shutdown. Because of this,
they tend to not call Shutdown()― instead (as in the case of the Jabber
add-on), they display a BAlert (IM_ERROR) notifying the user of the
connection error, but the account is considered active by Cardie (and
its threads are still existant, including its ProtocolLooper).
Zombies are bad, so this is redesigned somewhat with this commit:
Protocols should no longer call ChatProtocol::Shutdown() themselves,
they must send an IM_MESSAGE of IM_PROTOCOL_DISABLE to the app.
This will delete its ProtocolLooper, which in turn will send a
notification to the user and delete the ChatProtocol, and so
calling ChatProtocol::Shutdown().
In the included protocols, an IM_ERROR is sent right before
IM_PROTOCOL_DISABLE is sent if due to a connection error. This is not
required, but it is courteous to inform your user about the "why." :)
Connection errors are now sent to Cardie through an IM_ERROR message
(which appear in a BAlert), and an IM_PROTOCOL_DISABLED IM_MESSAGE is
sent to Cardie when the account is disabled/connection fails.
Sometimes a protocol's commands are dynamic, or change based on certain
events― and it's necessary in these cases that commands be reloaded.
The IM_PROTOCOL_RELOAD_COMMANDS message is now added to the API, which
will force Cardie to reload commands from the protocol.
The "room" template has been split into two seperate
templates― "join_room" and "create_room". Before, "room" was used in the
room creation window, but now that's delegated to "create_room".
"join_room" is used with the join window― so now, the add-on has total
control over the slots used to join/create rooms generally, if they
specify the templates. Even a "/join" command could be overriden by the
add-on.
Also, default templates are now in use. Rather than add-ons being
required to specify templates, there are sensible defaults included with
Cardie for each one.
