Homebrew Tap for Libra

This repository is a Homebrew tap for Libra, an AI agent-native version control system with Git on-disk compatibility.

Install

brew tap libra-tools/libra
brew install libra
libra --version

Upgrade

brew update
brew upgrade libra

Uninstall

brew uninstall libra
brew untap libra-tools/libra

Formula

The formula installs prebuilt Libra binaries from https://github.com/libra-tools/libra/releases and verifies the published SHA-256 digest for each supported platform.

Install Older Versions

This tap keeps Formula/libra.rb pointed at the latest released Libra version. To install an older version, install the formula from the tap commit that updated Libra to that version:

brew install https://raw.githubusercontent.com/libra-tools/homebrew-libra/<commit-sha>/Formula/libra.rb

Find the commit for a version with:

git clone https://github.com/libra-tools/homebrew-libra.git
cd homebrew-libra
git log --oneline -- Formula/libra.rb

Release automation should use commit messages in this format so versions are easy to find:

Update libra to v0.17.1446

Release Automation

The libra repository release workflow can update this tap after publishing GitHub Release assets:

scripts/update-formula.sh \
  v0.17.1446 \
  <sha256-for-libra-darwin-arm64> \
  <sha256-for-libra-linux-amd64> \
  <sha256-for-libra-linux-arm64>

Then commit the result directly to this repository's main branch:

git add Formula/libra.rb
git commit -m "Update libra to v0.17.1446"
git push origin main

Development

Run the local script test with:

bash test/update-formula-test.sh
