Add semver-string to your project's Gemfile and then bundle install.

gem 'semver-string', '~> 1'

Begin by requiring the gem:

require 'semver/string'

You can construct a Semver::String from a Ruby String:

version = Semver::String.parse('1.2.3-rc.1+build-123456789')

version.major #=> 1
version.minor #=> 2
version.patch #=> 3
version.pre_release #=> "rc.1"
version.build_metadata #=> "build-123456789"

You can also construct one from the semver components:

# only major, minor, and patch are required
version = Semver::String.new(
  major: 1,
  minor: 2,
  patch: 3,
  pre_release: 'rc.1',
  build_metadata: 'build-123456789')

version.to_s #=> "1.2.3-rc.1+build-123456789"

Semver::String objects can be compared and sorted. Sorting is done according to the rules defined at semver.org.

Semver::String.parse('1.10.0') < Semver::String.parse('1.2.0') #=> false
