Contributing to cmux

Prerequisites

  • macOS 14+
  • Xcode 15+
  • Zig (install via brew install zig)

Getting Started

  1. Clone the repository with submodules:

    git clone --recursive https://github.com/manaflow-ai/cmux.git
    cd cmux
    
  2. Run the setup script:

    ./scripts/setup.sh
    

    This will:

    • Initialize git submodules (ghostty, homebrew-cmux)
    • Build the GhosttyKit.xcframework from source
    • Create the necessary symlinks
  3. Build and run the debug app:

    ./scripts/reload.sh
    

Development Scripts

Script Description
./scripts/setup.sh One-time setup (submodules + xcframework)
./scripts/reload.sh Build and launch Debug app
./scripts/reloadp.sh Build and launch Release app
./scripts/reload2.sh Reload both Debug and Release
./scripts/rebuild.sh Clean rebuild

Rebuilding GhosttyKit

If you make changes to the ghostty submodule, rebuild the xcframework:

cd ghostty
zig build -Demit-xcframework=true -Doptimize=ReleaseFast

Running Tests

Basic tests (run on VM)

ssh cmux-vm 'cd /Users/cmux/GhosttyTabs && xcodebuild -project GhosttyTabs.xcodeproj -scheme cmux -configuration Debug -destination "platform=macOS" build && pkill -x "cmux DEV" || true && APP=$(find /Users/cmux/Library/Developer/Xcode/DerivedData -path "*/Build/Products/Debug/cmux DEV.app" -print -quit) && open "$APP" && for i in {1..20}; do [ -S /tmp/cmux.sock ] && break; sleep 0.5; done && python3 tests/test_update_timing.py && python3 tests/test_signals_auto.py && python3 tests/test_ctrl_socket.py && python3 tests/test_notifications.py'

UI tests (run on VM)

ssh cmux-vm 'cd /Users/cmux/GhosttyTabs && xcodebuild -project GhosttyTabs.xcodeproj -scheme cmux -configuration Debug -destination "platform=macOS" -only-testing:GhosttyTabsUITests test'

Ghostty Submodule

The ghostty submodule points to manaflow-ai/ghostty, a fork of the upstream Ghostty project.

Making changes to ghostty

cd ghostty
git checkout -b my-feature
# make changes
git add .
git commit -m "Description of changes"
git push manaflow my-feature

Keeping the fork updated

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

Then update the parent repo:

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

See docs/ghostty-fork.md for details on fork changes and conflict notes.
