Release Process

This document describes how to create releases for the lnk project using GoReleaser.

Prerequisites

• Push access to the main repository
• Git tags pushed to GitHub trigger releases automatically
• GoReleaser is configured in .goreleaser.yml
• GitHub Actions will handle the release process
• Access to the homebrew-lnk tap repository

Creating a Release

1. Ensure everything is ready

# Run all quality checks
make check

# Test GoReleaser configuration
make goreleaser-check

# Test build process
make goreleaser-snapshot

2. Create and push a version tag

# Create a new tag (replace x.y.z with actual version)
git tag -a v1.0.0 -m "Release v1.0.0"

# Push the tag to trigger the release
git push origin v1.0.0

3. Monitor the release

• GitHub Actions will automatically build and release when the tag is pushed
• Check the Actions tab for build status
• The release will appear in GitHub Releases
• The Homebrew formula will be automatically updated in homebrew-lnk

What GoReleaser Does

1. Builds binaries for multiple platforms:

   • Linux (amd64, arm64)
   • macOS (amd64, arm64)
   • Windows (amd64)

2. Creates archives with consistent naming:

   • lnk_Linux_x86_64.tar.gz
   • lnk_Darwin_arm64.tar.gz
   • etc.

3. Generates checksums for verification

4. Creates GitHub release with:

   • Automatic changelog from conventional commits
   • Installation instructions
   • Download links for all platforms

5. Updates Homebrew formula automatically in the homebrew-lnk tap

Manual Release (if needed)

If you need to create a release manually:

# Export GitHub token
export GITHUB_TOKEN="your_token_here"

# Create release (requires a git tag)
goreleaser release --clean

Testing Releases Locally

# Test the build process without releasing
make goreleaser-snapshot

# Built artifacts will be in dist/
ls -la dist/

# Test a binary
./dist/lnk_<platform>/lnk --version

Installation Methods

After a release is published, users can install lnk using multiple methods:

1. Shell Script (Recommended)

curl -sSL https://raw.githubusercontent.com/yarlson/lnk/main/install.sh | bash

2. Homebrew (macOS/Linux)

brew tap yarlson/lnk
brew install lnk

3. Manual Download

# Download from GitHub releases
wget https://github.com/yarlson/lnk/releases/latest/download/lnk_Linux_x86_64.tar.gz
tar -xzf lnk_Linux_x86_64.tar.gz
sudo mv lnk /usr/local/bin/

Version Numbering

We use Semantic Versioning:

• v1.0.0 - Major release (breaking changes)
• v1.1.0 - Minor release (new features, backward compatible)
• v1.1.1 - Patch release (bug fixes)

Changelog

GoReleaser automatically generates changelogs from git commits using conventional commit format:

• feat: - New features
• fix: - Bug fixes
• docs: - Documentation changes (excluded from changelog)
• test: - Test changes (excluded from changelog)
• ci: - CI changes (excluded from changelog)

Homebrew Tap

The Homebrew formula is automatically maintained in the homebrew-lnk repository. When a new release is created:

1. GoReleaser automatically creates/updates the formula
2. The formula is committed to the tap repository
3. Users can immediately install the new version via brew install yarlson/lnk/lnk

Troubleshooting

Release failed to create

1. Check that the tag follows the format vX.Y.Z
2. Ensure GitHub Actions has proper permissions
3. Check the Actions log for detailed error messages

Missing binaries in release

1. Verify GoReleaser configuration: make goreleaser-check
2. Test build locally: make goreleaser-snapshot
3. Check the build matrix in .goreleaser.yml

Changelog is empty

1. Ensure commits follow conventional commit format
2. Check that there are commits since the last tag
3. Verify changelog configuration in .goreleaser.yml

Homebrew formula not updated

1. Check that the GITHUB_TOKEN has access to the homebrew-lnk repository
2. Verify the repository name and owner in .goreleaser.yml
3. Check the release workflow logs for Homebrew-related errors
4. Ensure the homebrew-lnk repository exists and is accessible
