node-semver written in Ruby for comparison and inclusion of semantic versions and ranges.

NOTE: current master and releases >= 3 use keyword arguments instead of positional arguments to pass options. If you used SemanticRange.compare(a, b, true) in SemanticRange 2, in SemanticRange 3 use SemanticRange.compare(a, b, loose: true)

Add this line to your application's Gemfile:

gem 'semantic_range'

And then execute:

$ bundle

Or install it yourself as:

$ gem install semantic_range

SemanticRange.valid?('1.2.3') # true
SemanticRange.valid?('a.b.c') # false
SemanticRange.valid('1.2.3') # '1.2.3'
SemanticRange.valid('a.b.c') # nil
SemanticRange.clean('  =v1.2.3   ') # '1.2.3'
SemanticRange.filter(['0.9.0', '1.3.0', '1.5.0', '2.0.5'], '1.3.0 || <1.0.0 || >2.0.0') # ['0.9.0', '1.3.0', '2.0.5']
SemanticRange.satisfies?('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') # true
SemanticRange.gt?('1.2.3', '9.8.7') # false
SemanticRange.lt?('1.2.3', '9.8.7') # true

All functions support optional keyword arguments that modify default behavior. The options supported are:

• loose Be more forgiving about not-quite-valid semver strings. Any resulting output will always be 100% strict compliant. false by default.

Some functions support platform option:

• platform Changes behavior for 'Rubygems' and 'Packagist'. nil by default. See #59

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 tags, and push the .gem file to rubygems.org.
