This commit is in response to #1523.
Whispers are now only added to the `/mentions` tab if they also match a
user name or phrase highlight. On a related note, the `highlightVisual_`
member has been removed as it is no longer necessary.
* HighlightPhrase: Fix wrong documentation
* Use right constructor for new HighlightPhrases
* Fix preset highlights changing unintentionally
Prior to this commit, the callback for reacting to user input on the
highlight table (namely, `HighlightingPage::tableCellClicked`) only
checked for the row number in order to determine whether preset
highlights (self highlights, whispers, and subscriptions) need to be
updated. Hence, changing rows 0 through 2 in the "User Highlights" tab
would also update the preset highlights.
This commit adds a check to determine whether the callback was triggered
by the "Messages" highlight tab, or not.
Since #1320, subscription messages are treated as highlights in order to
allow customization. This caused subscription messages to highlight the
split(s) the message was received in. This is not intended behavior.
This commit fixes the issue by additionally checking if the
`Subscription` flag is set on a highlighted message.
* Support for user-defined sounds and colors
* Make color & sound columns selectable
* Add custom row for subscription highlights
* Add subscriptions to custom highlights and centrally manage highlight colors
* Dynamically update message highlight colors
* Introduce crossPlatformCopy()
It sets the text of the clipboard and also syncs it with the selection
clipboard if it is supported. Such behaviour is pretty common for X11
application on Unix-like Operating Systems.
* Fix clang-format remarks
* Fix weird clang-format config discrepancy between my machine and CI
* Remove clipboard argument from crossPlatformCopy
* Fix clang-format remarks
