rux.rb is the source-of-truth Homebrew formula for the rux compiler. It builds from source via CMake using Homebrew's LLVM (Apple's bundled clang is too old for Rux's C++26 sources).

Homebrew formulae live in a tap repository, not in this repo, so the steps below copy rux.rb into a tap.

The Mach-O linker backend landed after the v0.2.2 tag, so an existing release won't include it. Cut a new tag from a commit that has the backend:

# Optionally bump CMakeLists.txt project(... VERSION x.y.z) to match the tag
# so `rux --version` reports it.
git tag v0.3.0
git push origin v0.3.0     # push to the canonical repo (rux-lang/Rux)

Then create a GitHub release for that tag (the formula points at the auto-generated source tarball).

1. Set url in rux.rb to the release tarball, e.g. https://github.com/rux-lang/Rux/archive/refs/tags/v0.3.0.tar.gz.

2. Compute and paste the checksum:

   curl -L https://github.com/rux-lang/Rux/archive/refs/tags/v0.3.0.tar.gz | shasum -a 256

# Create a repo named exactly `homebrew-rux` under the rux-lang org, then:
git clone https://github.com/rux-lang/homebrew-rux.git
mkdir -p homebrew-rux/Formula
cp rux.rb homebrew-rux/Formula/rux.rb
cd homebrew-rux && git add Formula/rux.rb && git commit -m "Add rux formula" && git push

brew install --build-from-source ./rux.rb   # local smoke test before pushing
brew test ./rux.rb
brew audit --new --formula ./rux.rb          # lint before publishing

# After the tap is pushed, end users install with:
brew install rux-lang/rux/rux

• Produced executables are x86-64 only; on Apple Silicon they run via Rosetta 2. The rux compiler itself builds and runs natively on arm64.
• head "...", branch: "main" lets brew install --HEAD rux build from the tip of main for testing unreleased changes.
