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." :)
Like the notification sent when accounts are ready (IM_PROTOCOL_READY),
one's been added for when accounds have disconnected/are disabled:
IM_PROTOCOL_DISABLED.
Also, error BAlerts (created with IM_ERROR messages) are now more
detailed, showing the associated accounts' name in the header.
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.
When a new message is posted (or the user is messaged), the room's item
in the roomlist is now highlighted, like Vision.
Chat also auto-scrolls when new messages are posted.
If the user's in a one-on-one chat, notify on every message― otherwise,
only notify when the user's name/ID is mentioned by another user.
Notifications should be managed by roomflags, but that's for another
time.
Base-level replacement of the Vision-derived text RunView― a couple
important features supported by the replacee haven't been implemented yet,
including:
* Right-click menu
* URL-highlighting/selection
* Emote support
The StatusView (below the roomlist) now shows a default icon if no
accounts have associated avatars, and will use an account's cached avatar
if available.
The BTextBox used for sending messages has been moved from the main
window to individual ConversationViews, allowing seperate histories,
texts, etc., to exist in different conversations.
EditingFilter (a filter that hooked into MainWindow) was previously used
to field special key combos with this textbox, including "ENTER" for
sending, but this has been replaced with a new textview subclass
(SendTextView).
It doesn't make sense to lump the user themself with their contacts
list― their Contact object is now stored seperately.
BBitmap loading for RosterItems are fixed, as well.
Fixes#33
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.
The settings file-hierarchy has been changed a bit:
* Cardie/
* preferences
* Accounts/
* Cache/
* Accounts/
* Add-Ons/
`Cardie/Protocols` is now `Cardie/Accounts`, and the cache directory
has been split into two. `Cache/Accounts/` is for account-specific
cached data (e.g., cached roster icons, data, etc.), and
`Cache/Protocols` is for protocol-wide settings/data.
For purple, this will be used as the user's libpurple directory,
which has been moved from the default of `~/.purple` (yikes!)
Some plugin search-paths have been given to purple, too― lib
directories + "/purple2/", and Cardie/Cache/Add-Ons/purple/plugins/.
Registration of custom chat commands and menu-items for protocols was
done by the IM_REGISTER_* messages, and is now done through direct calls
to the CayaProtocol object.
The new model for call/message for protocols is this: Temporary
information (chat messages, roster members, etc.) should be accessed
through messages. Relatively static data (protocol name, commands)
should be accessed through direct calls to the protocol object.
Now roster members can be deleted through the RosterEditWindow.
IM_CONTACT_LIST_REMOVED_CONTACT was renamed to
IM_CONTACT_LIST_CONTACT_REMOVED to fit style of other API messages.
Fixes#1.
Roster members' can now be edited (through Roster->Edit Roster / CMD+R)
TemplateWindows can now be populated through sending any IM_MESSAGE to
it (it will assume the slots of the message correspond to the
template's).
IM_CONTACT_LIST_ADDED_CONTACT was removed (for redundancy), and
IM_CONTACT_LIST_EDIT_CONTACT was added.
The base for roster management (RosterEditWindow) has been made, and
adding new contacts works. Up next is contact removal and editing.
This leverages a new template (as defined in a protocol's
CayaProtocol::SettingsTemplate()), "roster," which should contain all
slots pertinent to editing/adding a contact member.
Two new API messages were added for this― IM_CONTACT_LIST_CONTACT_ADDED
and IM_CONTACT_LIST_CONTACT_REMOVED. The former will functionally just
be IM_CONTACT_INFO, but with some semantical meaning.
A new CayaMessage (CAYA_EDIT_ROSTER) was also added.
TemplateWindow was also edited to this end: Now, like RosterWindow/View,
it can be given a specific accounts' instance id, and it will prevent
the selection of another account. A new constructor was also added, to
allow a ProtocolTemplate to be explicitly passed to it― probably from
the program itself.
Most of RosterWindow's special functions have been split into a special
BGroupView (including both the roster search-box and roster list),
RosterView.
This will give some more flexibility in other uses of the roster list.
In addition, RosterViews can be tied to a specific account by its
looper's instance ID, allowing it to either show all contacts (globally;
if the ID is set to -1) or only those of the specified account.
This can be useful, for example, when inviting contacts to a room―
you can only invite contacts that use the same protocol, and are
associated with your account, so showing all contacts doesn't make
sense.
The SearchBarTextControl class was removed, as it isn't particularly
necessary.
Explicit room-creation using protocol's own "room" template is now
supported.
Two new protocol API messages were added― IM_CREATE_ROOM and
IM_ROOM_CREATED, which are parallels to IM_CREATE_CHAT and
IM_CHAT_CREATED. Rather than the latter two, though, these are wholy
based on the "room" template― their slots are completely determined by
the protocol.
A generic "TemplateWindow" was created, which allows catch-all creation
of windows that leverage protocols' templates. It's used for the
room-creation window (Chat->New Room / Alt+N), for example.
At some point, it ideally should replace even the JoinRoom window, and
maybe others.
A nice templating system is used for account settings dialogues― the
required slots are specified by the protocol, and are reflected in the
settings dialogue.
To generalize this templating system (and eventually use elsewhere),
ProtocolSettings was split into two classes― ProtocolSettings and
ProtocolTemplate.
The CayaProtocol::SettingsTemplate() call was also edited to require a
string parameter, naming the specific template that should be returned.
"account" is used for the account settings dialogue, and other values
are TBA.
