💎 Gem Digest

A powerful CLI tool that analyzes your Gemfile.lock, fetches the latest gem versions from RubyGems, and categorizes updates by semantic versioning (major, minor, patch).

• Smart Analysis: Parses Gemfile.lock and compares with latest versions from RubyGems
• Semantic Categorization: Groups updates by major, minor, and patch versions
• Multiple Output Formats: Console output with colors and tables, or Markdown reports
• Comprehensive Reporting: Shows current vs latest versions with source information
• Cross-Platform: Works on Linux, macOS, and Windows

Add this line to your application's Gemfile:

gem 'gem-digest'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install gem-digest

Analyze your current directory's Gemfile.lock:

$ gemd analyze

# Specify a different Gemfile.lock path
$ gemd analyze --gemfile-lock /path/to/Gemfile.lock

# Generate a markdown report
$ gemd analyze --format markdown --output-dir reports

# Show gems that are already up to date
$ gemd analyze --show-up-to-date

# Verbose output
$ gemd analyze --verbose

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

$ bundle exec rspec

$ bundle exec rubocop
