We need this to get info about the padding, even if we do derive the
grid and screen size separately.
In the future this should possibly be changed to a message that only
sends the padding info and nothing else.
If this was Swift code, we'd be using a strong reference, which would
retain the layer for us and release it when the object is deallocated,
but this is Zig land so we have to do that manually.
NOTE: We don't *have* to do this, but it fits much better with Zig idiom
and hopefully avoids potential future footguns. We should do this to any
autoreleased objects that we persist a reference to in a Zig struct.
This commit is very large, representing about a month of work with many
interdependent changes that don't separate cleanly in to atomic commits.
The main change here is unifying the renderer logic to a single generic
renderer, implemented on top of an abstraction layer over OpenGL/Metal.
I'll write a more complete summary of the changes in the description of
the PR.
This wasn't working before but it just requires a restart of the machine
for the changes to take effect. The namespace runners have this prebuilt
so this should work now.
The other workaround was flaky for unknown reasons so I'd prefer to go
back to this.
We were depending on $GHOSTTY_RESOURCES_DIR for two reasons:
1. To locate our script-adjacent bash-preexec.sh script
2. To restrict our script's execution to environments in which
$GHOSTTY_RESOURCES_DIR is available (i.e. Ghostty-only shells)
For (1), we can instead determine our directory using $BASH_SOURCE[0].
This is slightly differently than our previous behavior, where we'd
always load bash-preexec.sh from the $GHOSTTY_RESOURCES_DIR hierarchy,
even if ghostty.bash from source from somewhere else on the file system
... but we never relied on that behavior, even in development.
For (2), there's no harm in source'ing this script outside of Ghostty,
and if that does become a concern, we can restore this condition or use
something more targeted based on those specific cases.
Historically, I believe (2) was in place to enable (1), so addressing
(1) removes the need for (2).
And lastly, none of the other shell integration scripts depend on
$GHOSTTY_RESOURCES_DIR.
Updates all copyright notices to include "Ghostty contributors" to
reflect the fact that Mitchell is not the sole copyright owner.
Also adds "Ghostty contributors" to the author section in the manpages,
linking https://github.com/ghostty-org/ghostty/graphs/contributors for
proper credit.
This updates our build script and CI to support Xcode 26 and macOS
Tahoe. **This doesn't update the Ghostty app to resolve any Tahoe
issues.**
For CI, we've added a new build job that runs on macOS Tahoe with Xcode
26. I've stopped short of updating our tip release job, since I think I
want to wait until I verify a bit more about Tahoe before we flip that
bit. Also, ideally, we'd run Xcode 26 on Sequoia (macOS 15) for
stability reasons and Namespace doesn't have Xcode 26 on 15 yet.
For builds, this updates our build script to find Metal binaries using
`xcodebuild -find-executable` instead of `xcrun`. The latter doesn't
work with Xcode 26, but the former does and also still works with older
Xcodes. I'm not sure if this is a bug but I did report it: FB17874042.
