Release

Parse $ARGUMENTS for major, minor, or patch. Default to patch if empty or unrecognized.

4. Read Current Version

cd ~/eulard && node -p "require('./package.json').version"

5. Compute Next Version

Split the current version into major.minor.patch and increment the appropriate segment:

• major — increment major, reset minor and patch to 0
• minor — increment minor, reset patch to 0
• patch — increment patch

6. Gather Commits Since Last Tag

cd ~/eulard && git log $(git describe --tags --abbrev=0 2>/dev/null || git rev-list --max-parents=0 HEAD)..HEAD --oneline --no-decorate

If there are no commits since the last tag, STOP and tell the user there is nothing to release.

7. Generate Changelog Section

Categorize each commit by its prefix. Recognized prefixes and their display names:

Commits without a recognized prefix go under Other.

Build a changelog section in this format:

## v{version} — {YYYY-MM-DD}

### Features
- commit message (short sha)

### Bug Fixes
- commit message (short sha)

...

Only include category headings that have commits. Strip the prefix from the commit message in the list.

8. Update CHANGELOG.md

If ~/eulard/CHANGELOG.md does not exist, create it with this header:

# Changelog

All notable changes to eulard are documented in this file.

Prepend the new version section immediately after the header line (after the blank line following the description). Existing entries stay below.

9. Update package.json Version

cd ~/eulard && npm version {version} --no-git-tag-version

This updates the version field in package.json (and package-lock.json if present) without creating a git tag.

10. Commit

cd ~/eulard && git add CHANGELOG.md package.json package-lock.json 2>/dev/null; git add CHANGELOG.md package.json
cd ~/eulard && git commit -m "release: v{version}"

11. Tag

cd ~/eulard && git tag v{version}

12. Push

cd ~/eulard && git push origin main --follow-tags

13. Create PR to Stable

Use the changelog section generated in step 7 as the PR body.

cd ~/eulard && gh pr create --base stable --head main \
  --title "Release v{version}" \
  --body "$(cat <<'EOF'
{changelog section from step 7}

---
Merging this PR will auto-deploy to production.
EOF
)"

14. Report

## Release v{version}

**PR**: https://github.com/kelihi/eulard/pull/<number>
**Tag**: v{version}
**Bump**: {old_version} -> {version} ({bump_type})

### Changelog
{changelog section}

**Next step**: Merge the PR to `stable` to auto-deploy to production (https://eulard.kelihi.com).

Error Handling

• If git push fails, suggest git pull --rebase origin main and retry
• If gh pr create fails because a PR already exists from main to stable, find it and show its URL
• If there are no commits since the last tag, abort with a clear message — nothing to release
