release-prepare

Prepare Release

Analyzes commits since the last release and prepares all release artifacts.

Usage

/release-prepare auto       # Auto-detect version from commits
/release-prepare minor      # Force minor version bump
/release-prepare major      # Force major version bump
/release-prepare patch      # Force patch version bump

What This Does

1. Analyze Commits: Get all commits since last release tag
2. Determine Version: Calculate version bump based on commit types
3. Generate Changelog: Create changelog entries grouped by type
4. Create Release Notes: Generate comprehensive release notes
5. Prepare Files: Show what version files need updating

Workflow

Step 1: Get Last Release

Find the most recent release tag and analyze commits since then:

# Get last release tag
LAST_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "")
echo "Last release: ${LAST_TAG:-'No previous release'}"

# Count commits since last release
if [ -n "$LAST_TAG" ]; then
  COMMIT_COUNT=$(git rev-list --count $LAST_TAG..HEAD)
else
  COMMIT_COUNT=$(git rev-list --count HEAD)
fi
echo "Commits since last release: $COMMIT_COUNT"

Step 2: Analyze Commit Types

Parse commits using conventional commit format:

# Get commits since last tag
if [ -n "$LAST_TAG" ]; then
  COMMITS=$(git log $LAST_TAG..HEAD --pretty=format:"%s")
else
  COMMITS=$(git log --pretty=format:"%s")
fi

# Count by type
FEAT_COUNT=$(echo "$COMMITS" | grep -c "^feat" || echo "0")
FIX_COUNT=$(echo "$COMMITS" | grep -c "^fix" || echo "0")
BREAKING_COUNT=$(echo "$COMMITS" | grep -c "!" || echo "0")
BREAKING_FOOTER=$(echo "$COMMITS" | grep -c "BREAKING CHANGE" || echo "0")

echo "Features: $FEAT_COUNT"
echo "Fixes: $FIX_COUNT"
echo "Breaking changes: $((BREAKING_COUNT + BREAKING_FOOTER))"

Step 3: Determine Version Bump

Based on argument or auto-detection:

Auto-detection logic:

• Any breaking changes (! or BREAKING CHANGE) → MAJOR
• Any features (feat:) → MINOR
• Only fixes/docs/chores → PATCH
