The property returns NSNotFound when there is no selection. This seems to be consistent with NSArrayController’s selectionIndex (but inconsistent with many other views, like NSTableView, which return -1 when there is no selection).
While AppKit identifiers are generally strings, which have more flexibility, I think this is mainly because NSUUID was introduced later, and for tab items, identifiers must be unique, which is not enforced (or implied) when using strings.
Apparently the window’s delegate is not used for context menu actions in full screen mode, although NSApp’s targetForAction: does find the receiver, so this appears to be a framework bug.
Some users report a significant delay from executing mate until the TextMate window is brought to front.
The debug information can be extracted by running the following in a terminal:
log show --predicate 'subsystem = "com.macromates.TextMate" && category = "BringToFront"'
Alternatively use `stream` instead of `log` to get a live stream of debug output.
See `man log` for options such as `--start date/time` (to limit the query to e.g. the last 10 minutes)
This is because we may sometimes want to enable implicit animations when updating this property, by making it read-only we limit places from where it can be updated, to make it easier to audit the code.
Currently no-one outside the class actually uses the property, so we could (and may) make it private.
For users on an OS earlier than 10.12, the tab bar will always be visible, even when configured to not show for windows with only a single document (tab).
This makes the title bar render in the same color as it did prior to building on 10.14, so that the current tab colors match.
It does however make sheets appear from “above” the title bar and makes the Dark Mode style darker, so this is just an intermediate fix until the tab bar gets revamped for 10.14.
Also, switch to use the new divider styles in most places. The remaining usage of the old "OakCreateLine" functions are in the OakChooser windows. These will be refactor for better dark mode support next.
For example when implicitly opening documents because we are duplicating the active document in the file browser, or closing a document because its file got deleted in the file browser, we want focus to stay in the file browser.
Previously we refocused the file browser when closing documents as a result of deleting files.
For duplicating files, this seemed to work because the file browser would not start editing the new file name until it had detected disk changes, thus it would happen after a slight delay.
