Generate Changelog

Generate a human-readable changelog from git commits, grouped by conventional commit type.

Usage

/changelog [range]

• •No argument: commits since last tag, or last 20 commits if no tags exist
• •With argument: use as git log range (e.g., v1.0..HEAD, main..feat/branch)

Process

1. Determine Range

If $ARGUMENTS is provided, use it as the range.

Otherwise, find the latest tag:

git describe --tags --abbrev=0 2>/dev/null

• •If a tag exists, use <tag>..HEAD
• •If no tags, use --max-count 20 (no range, safe for repos with fewer than 20 commits)

2. Fetch Commits

If a range was determined:

git log <range> --pretty=format:"%h %s" --no-merges

If no tags and no argument (fallback):

git log --max-count 20 --pretty=format:"%h %s" --no-merges

Exclude merge commits to keep the changelog clean.

3. Group by Type

Parse conventional commit prefixes and group:

• •Features (feat:)
• •Bug Fixes (fix:)
• •Refactoring (refactor:)
• •Tests (test:)
• •Chores (chore:)
• •Documentation (docs:)
• •Other (commits without a recognized prefix)

4. Format Output

## Changelog

**Range**: `v1.0..HEAD` (12 commits)

### Features
- Add terminal resize support (a1b2c3d)
- Add repo deletion with cascade (d4e5f6a)

### Bug Fixes
- Fix WebSocket reconnection on timeout (b7c8d9e)

### Refactoring
- Refactor PTY manager for multi-session support (f0a1b2c)

### Chores
- Update dependencies (c3d4e5f)

Notes

• •Strip the prefix from commit messages in the output (e.g., feat: Add X becomes Add X)
• •Include the short commit hash for reference
• •Skip empty sections — only show categories that have commits
• •If all commits lack prefixes, just list them without categories
