Fixes#2745
GTK uses a delayed surface initialization since we initialize on
GTKGLArea realize not on the actual callback. Because of that, our
inherited directory doesn't always work since that depends on a
previously focused widget.
This copies our desired inherited directory to an allocation so that we
can set it during realize.
adw_application_window_destroy and gtk_application_window_destroy do not
exist. I believe that this didn't trigger a compile error because the
errdefer got compiled out because there are no potential error returns
after this code in the function.
Rather than storing a list of errors we now store a list of
"diagnostics." Each diagnostic has a richer set of structured
information, including a message, a key, the location where it occurred.
This lets us show more detailed messages, more human friendly messages, and
also let's us filter by key or location. We don't take advantage of
all of this capability in this initial commit, but we do use every field
for something.
This takes advantage of CSS variables and color expressions to improve
the `window-theme=ghostty` support. The only visibile difference from
the previous implementation is that the header bar will darken if the
Ghostty window is in the background, which is standard for GTK apps.
This is conditional at runtime. If Ghostty detects that you're running
against GTK 4.16 or newer it will use the CSS variables and color calcs.
If you're running against older versions it will use CSS classes to
achieve nearly the same effect.
This simplifies the math for calculating scroll vectors based on mouse
scroll events. This was done to fix inverted horizontal scrolling on
macOS with natural scrolling enabled. Many assertions were added for
assumptions and our preconditions are clearly documented.
The preconditions are:
* Apprt scroll offsets are negative down/left, positive up/right
* Terminal vertical scroll is postive down, negative up (opposite
since scroll for a terminal means how many rows to move down).
* `Surface.scrollCallback` is always call with an apprt offset.
* Apprt is responsible for implementing natural scrolling. Surface
always assumes negative is down/left.
macOS 12 is officially EOL by Apple and the project only supports
officially supported versions of macOS. Once publicly released, users on
older macOS versions will have to use older released builds.
GTK4 version 4.16 split the environment variable `GDK_DEBUG` into `GDK_DEBUG`
and `GDK_DISABLE`. This is being done by using the helper function `atLeast` to
handle certain versions accordingly.
`GSK_RENDERER` also only needs to be set in later GTK versions (>=1.14.0).
