GhosttyKit builds

When rebuilding GhosttyKit.xcframework, always use Release optimizations:

cd ghostty && zig build -Demit-xcframework=true -Dxcframework-target=universal -Doptimize=ReleaseFast

Submodule workflow

Ghostty changes must be committed in the ghostty submodule and pushed to the manaflow-ai/ghostty fork. Keep docs/ghostty-fork.md up to date with any fork changes and conflict notes.

cd ghostty
git remote -v  # origin = upstream, manaflow = fork
git checkout -b <branch>
git add <files>
git commit -m "..."
git push manaflow <branch>

To keep the fork up to date with upstream:

cd ghostty
git fetch origin
git checkout main
git merge origin/main
git push manaflow main

Then update the parent repo with the new submodule SHA:

cd ..
git add ghostty
git commit -m "Update ghostty submodule"

Submodule safety

When modifying a submodule, always push the submodule commit to its remote main branch before committing the updated pointer in the parent repo. Never commit on a detached HEAD or temporary branch; the commit can be orphaned and lost.

Verify with:

cd <submodule> && git merge-base --is-ancestor HEAD origin/main

Detailed reference

• Read references/submodule-safety.md before committing submodule pointer updates or resolving Ghostty fork conflicts.
