First, this commit modifies libghostty to use a single unified action
dispatch system based on a tagged union versus the one-off callback
system that was previously in place. This change simplifies the code on
both the core and consumer sides of the library. Importantly, as we
introduce new actions, we can now maintain ABI compatibility so long as
our union size does not change (something I don't promise yet).
Second, this moves a lot more of the functions call on a surface into
the action system. This affects all apprts and continues the previous
work of introducing a more unified API for optional surface features.
This was breaking various other features:
- Popovers stopped working
- Split divider drag gestures stopped working
For now we document the top part of the window is draggable... we
can look into removing that limitation later.
This only works on macOS 15 because it uses the new `pointerStyle` API.
I don't have the interest to backport this to older macOS versions but
I'm happy to accept a PR if someone else wants to do it.
Fixes#1833
This is an attempt to simplify the logic that has organically grown
convoluted over time with regards to how the titlebar and tab bar is
styled.
This field is one unified field that ONLY addresses titlebar and tab bar
styling. It can be one of "native", "transparent", or "tabs". The
"native" field is the new behavior in this commit: it makes the titlebar
and tab bar appearance be absolutely native. We do not color anything
(if we do its a bug).
The "transparent" option is the previous `macos-titlebar-tabs = false`
setting where the titlebar/tab bar is native but colored according to
the window background color.
The "tabs" option is `macos-titlebar-tabs = true`.
The `window-theme = auto` affect on titlebar appearance has been
removed. Now, the titlebar will NEVER be styled with "native" and MAY be
styled with "transparent" and will ALWAYS be styled with "tabs" (since
that's a totally custom look anyways).
Fixes#1771
I'm not convinced this fix won't regress some other behavior, but in my
titlebar tab and native tab modes with and without transparency, this
has looked okay to me.
