`Array.prototype.splice` will return the array of removed items, not a new array. The array operated on is actually modified in-place.
This was causing a few weird things to happen: https://github.com/vector-im/riot-web/issues/4511 and https://github.com/vector-im/riot-web/issues/4533. This should fix both of them but it is concerning that doing the tab completion is required to reproduce. Let's just see how this goes before closing the issues.
Thanks @turt2live for reproducing both bugs, giving enough information for a fix :)
Accepting an invite would cause a room to arrive via /sync only for it to throw an error in the auto complete code and cause the client to go wibbly (infinite spinner or preview bar).
The logs that lead to the debugging of this are https://github.com/matrix-org/riot-web-rageshakes/issues/239
Hopefully the error being throw isn't totally unrelated but looking at the sync handling for inviteRooms in sync.js, new rooms are stored and _then_ the Room event is emitted. The Room event could trigger setUserListFromRoom, which is where the bug was. So the room should have been stored regardless of this bug and the client should have been recoverable by swapping away and viewing the room again.
Which are:
- the emoji to complete is at the start of the query
- there is a whitespace character before the emoji
- there is an emoji before the emoji (so that several emoji can be input in-a-row)
Fixes https://github.com/vector-im/riot-web/issues/4498 (although it seems to be fixed through some other fix)
QueryMatcher: sort results based on the position of the query within the matching value. The closer to the beginning of the word, the higher the result apears.
UserProvider: perf improvement (slice early) and refactor onUserSpoke
Plaintext emojis that start with ":" will also match against the shorthand regex but the match won't include the important part of the plaintext emoji. This means some emoji like ":)" won't be matched.
To fix this, put the ascii emoji regex first so that the match will be plaintext or otherwise it will fall through to the shorthand match (if there is one).
Fixes https://github.com/vector-im/riot-web/issues/4467
When a fully plaintext, ascii emoji is typed like ";-)", pressing tab will suggest emojione to replace it with based off of the meta data provided by emojione.
e.g. the aliases_ascii for `😃` are [":D",":-D","=D"] so typing ":D *tab*" will insert a real 😃
As of v2.7.2, fuse.js introduces a regression where the second argument to the constructor `Fuse` is assumed to be an object. There was one instance where we were not passing any argument. This fixes that.
