Usage
gem_changelog_diff
Run from a project directory with a Gemfile.lock. The tool detects outdated gems via bundle outdated, looks up their GitHub repositories, fetches release notes, and displays a formatted changelog diff.
gem_changelog_diff version # Print version
gem_changelog_diff --version # Same as above
GitHub Authentication
To avoid the 60 requests/hour unauthenticated rate limit, provide a GitHub personal access token:
gem_changelog_diff --token ghp_your_token
# or
export GITHUB_TOKEN=ghp_your_token
gem_changelog_diff
Output Control
gem_changelog_diff --verbose # Show detailed status messages
gem_changelog_diff --quiet # Suppress warnings
gem_changelog_diff --no-color # Disable colored output
The tool also respects the $NO_COLOR environment variable.
