Changelog CLI

A command line tool for managing changelogs following the Keep a Changelog format.

Adding Entries

To add a changelog entry, use the changelog add command:

changelog add --type <TYPE> <DESCRIPTION>

Change types:

• added (alias: a) – New features
• changed (alias: c) – Changes in existing functionality
• deprecated (alias: d) – Soon-to-be removed features
• removed (alias: r) – Removed features
• fixed (alias: f) – Bug fixes
• security (alias: s) – Security fixes

Entry Style Guide:

Voice & Tense:

• Use present tense to describe new behavior: “X now supports Y”
• Use past tense for removals/fixes: “Fixed X”, “X has been removed”
• Describe the state, don’t command: “Commands now accept…” not “Make commands accept…”

Formatting:

• Description should be lowercase (except proper nouns)
• Keep descriptions concise but informative

Examples:

changelog add --type added "commands now accept multiple arguments"
changelog add --type fixed "login bug that prevented oauth flow"
changelog add --type changed "error messages now include more context"
changelog add --type removed "deprecated v1 api endpoints have been removed"

To add an entry to a specific version instead of Unreleased:

changelog add --type fixed --version 1.0.1 "critical security patch"

Releasing Versions

To release the Unreleased section as a new version:

# Automatic semver increment
changelog release major  # 1.0.0 -> 2.0.0
changelog release minor  # 1.0.0 -> 1.1.0
changelog release patch  # 1.0.0 -> 1.0.1

# Explicit version
changelog release 1.0.0

# With custom date
changelog release 1.0.0 --date 2025-01-01

Reviewing Git Commits

To interactively review git commits and add them to the changelog:

changelog review

This opens an interactive selection interface similar to git rebase -i. Commits with conventional commit prefixes (feat:, fix:) are pre-selected. After selection, an editor opens to categorize and reword entries.
