Now, instead of using Utils.cpp's AccountCachePath and AddOnCachePath,
and add-on should implement ChatProtocol::SetAccountCachePath and
ChatProtocol::SetAddOnCachePath.
In addition, most path-related functions in Utils now return BPaths― and
some of interest to chat add-ons can accept the path given by
ChatProtocol::SetAccountCachePath as the main argument.
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.
Pidgin's icon has been borrowed as the add-on's icon― and protocol icons
are taken from `$DATA_DIR/pixmaps/Pidgin/protocol/`, just as
Pidgin/libpurple installs them.
Any third-party plugins will also install their icons there, even
if just locally.
I've updated the libpurple package to include these icons, hopefully
that'll get merged.
Now the purple add-on's starting to come together with a clear
structure:
* Add-on sends IM_MESSAGES etc to the server for processing
* Server sends all (reply/etc) messages to add-on, which sends
to app
It's worth noting that on the add-on's side, no looper or handler is
used for receiving messages, it's all through sending serialized
BMessages to the add-on's connect_thread buffer.
PurpleAccounts are now reliably associated with Cardie's account names
and the thread ID of their respective connect_thread.
The GLib main-loop is gone over regularly thanks to a message runner.
Now, the add-on can log into/create accounts, connect to them, and send
the IM_PROTOCOL_READY notification to Cardie as appropriate.
The libpurple add-on has been split into two parts― a background process
that will actually interface with libpurple, and an add-on that acts as
intermediary between Cardie and the process. This helps prevent
redundancy, and is giving me a lot less trouble that directly loading
libpurple.
The protocol amount and names are now returned by the add-on (through
protocol_count() and protocol_at() respectively)― you can see them in
Preferences' protocol list.
