Add setting for setting the history visibility.
Note this setting can only be read not set for Quotient version < 0.7 as there is no event definition for a history visibility state event and it doesn't seem worth creating one when not needed with Quotient 0.7.
BUG: 457840
This add the final list of settings in the main setting window as a new page notifications as there are quite a few now. This completes previous work on push rules giving the ability to set the default global rules. Adding keyword rules is also now supported.
This also uses the new mobileform layout. The settings are designed to give some visual feedback as options for whether notifications are on/off, play a sound or are highlighted are chosen. The left icon is designed to mimic the notification dot in the roomlist. The whole mobileform delegate can also be clicked to cycle through the available options.
The rationale for whether an option is available is as follows:
- Highlight is not available if would lead to every message in a room being highlighted
- Keyword notifications cannot be switched off instead the rule is just deleted
- Only keyword rules can be deleted, default rules cannot be touched
There is also rules plumbed in for features that don't exist in neochat yet, i.e. encrypted chats and rooms, calls. I figured I may as well plumb these in and test them my plan was to hide them before merge, they can then be unhidden when the features are complete.

This is the start of a significant refactoring of everything related to sending messages, which is roughly:
- the chatbox
- action handling
- message sending on the c++ side
- autocompletion of users/rooms/emojis/commands/things i forgot
Notable changes so far include:
- ChatBox is now a ColumnLayout. As part of this, i removed the height animations for now. <del>as far as i can tell, they were broken anyway.</del> I'll readd them later
- Actions were refactored to live outside of the message sending function and are now each an object; it's mostly a wrapper around a function that is executed when the action is invoked
- Everything that used to live in ChatBoxHelper is now in NeoChatRoom; that means that the exact input status (text, message being replied to, message being edited, attachment) is now saved between room switching).
- To edit/reply an event, set `NeoChatRoom::chatBox{edit,reply}Id` to the desired event id, `NeoChatRoom::chatBox{reply,edit}{User,Message}` will then be updated automatically
- Attachments behave equivalently with `NeoChatRoom::chatBoxAttachmentPath`
- Error message reporting from ActionsHandler has been fixed (same fix as in !517) and moved to NeoChatRoom
Broken at the moment:
- [x] Any kind of autocompletion
- [x] Mentions
- [x] Fancy effects
- [x] sed-style edits
- [x] last-user-message edits and replies
- [x] Some of the actions, probably
- [x] Replies from notifications
- [x] Lots of keyboard shortcuts
- [x] Custom emojis
- [x] ChatBox height animations
TODO:
- [x] User / room mentions based on QTextCursors instead of the hack we currently use
- [x] Refactor autocompletion stuff
- [x] ???
- [x] Profit
This commit adds the ability to set the master push rule and set push rules for individual rooms as per the matrix spec. See https://spec.matrix.org/v1.3/client-server-api/#push-rules.
The master push rule is just on/off and uses the existing notification setting in general setting to enable/disable the server default master push rule .m.rule.master.
For each room there is now a page in the room setting that allows the following to be set:
- Default
- All messages
- @mentions and keywords
- off
New room or override rules are added/removed to achieve this.
There is also functionality to check the master/room notification state whenever the setting menu is entered. This allows the status to be updated if changed in another client or get the initial state for a room as it isn't stored.
Note - There is currently no menu items in the room list for setting the room push rule settings. This will be added in a later commit, the aim is to focus on making sure the technical implementation is good for now.
### Summary
This merge request adds a horizontal bar at top of room list, which shows spaces. By clicking on a space, user can filter out rooms belonging only to that specific space.
### Pending/ Help needed
#### Segfault when loading active connection on startup
Refer `void SortFilterRoomListModel::cacheSpaceHierarchy()` ([link](8c372800d7 (b969e462c30df43ef3714ea441948d8d8027f6a0_117_126))) in `src/sortfilterroomlistmodel.cpp`.
On [line 129](8c372800d7 (b969e462c30df43ef3714ea441948d8d8027f6a0_117_129)), I have called `connection->allRooms()`, which segfaults if the active connection hasn't been loaded yet. Is there a way to ensure that `Controller::instance().activeConnection()` on line 128 waits till connection is loaded?
#### Avatars
Avatars on space horizontal bar aren't aligned to vertical middle. I'll need help with that.
Using the code below doesn't help with padding
```qml
delegate: QQC2.Control {
topPadding: 10
contentItem: Kirigami.Avatar { ..... }
}
```
This complains about uninitialized properties in `Kirigami.Avatar`. (`id`, `currentRoom`, `avatar`, `index` are properties utilized during run time)
After we get around these two issue, this MR will be ready from my side.
This adds support for displaying recieved spoilers, but not sending
them. Spoilers are displayed as a black rectangle, and can be clicked on
to be revealed. If the last message in a channel was a spoiler, it is
not shown on the left sidebar.
The spoiler blackening is done in CSS, but to check if a message
contains a spoiler for determining if it should cause a different cursor
to be displayed and if it should be shown in the sidebar, a simple check
of if the message contains "data-mx-spoiler" is used.
* Message with multiple mentions are not broken in IRC. Fix#267
* Editing a message won't remove mentions anymore
(cherry picked from commit bb3b3bc088)
Now lastEvent() return the last event and lastActiveTime() and
lastEventToString() are convenient functions to get the visual
representation and the timestamp.
We are also now fetching new events when the timeline is empty
so that we can correctly order the rooms. In the future, we should
instead probably cache the last event in an SQLite database to optimize
the startup time.
This also ignore state event when the configuration ask to ignore them.
Fix: #97
The C++ header signature was using a C++17 type alias and this was
confusing MOC. Just changing the signature to the more verbose type name
fix the bug.
