GhosttyKit builds
Always rebuild the xcframework with Release optimizations:
cd ghostty && zig build -Demit-xcframework=true -Dxcframework-target=universal -Doptimize=ReleaseFast
Submodule workflow
Ghostty changes are committed in the ghostty submodule and pushed to the manaflow-ai/ghostty fork. Keep docs/ghostty-fork.md current with fork changes and conflict notes.
Always run git remote -v first and push to whichever remote is manaflow-ai/ghostty. .gitmodules sets the submodule URL to that fork, so in a normal checkout it is origin; older setups tracked upstream as origin and added the fork as manaflow. Substitute the right name below.
cd ghostty
git remote -v # find the manaflow-ai/ghostty remote (usually origin)
git checkout -b <branch>
git add <files>
git commit -m "..."
git push origin <branch>
To pull in changes from upstream ghostty-org/ghostty, add it as an explicit remote first, since no checkout has it by default:
cd ghostty
git remote add upstream https://github.com/ghostty-org/ghostty.git # once
git fetch upstream
git checkout main
git merge upstream/main
git push origin main
Then record the new SHA in the parent repo:
cd ..
git add ghostty
git commit -m "Update ghostty submodule"
Submodule safety
For any submodule (ghostty, vendor/bonsplit, homebrew-cmux), push the submodule commit to its remote branch before committing the updated pointer in the parent repo. Never commit on a detached HEAD or a temporary branch: the parent then points at a SHA unreachable from any remote branch, and a future checkout or CI job fails to fetch it.
Verify the commit is reachable from the branch the pointer should track, using the remote you just pushed to:
cd ghostty && git fetch origin main && git merge-base --is-ancestor HEAD origin/main
