A simple gem containing one class SemverCheck::Compare to compare SemVer strings.
Install the gem and add to the application's Gemfile by executing:
$ bundle add semver_check
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install semver_check
The Compare class includes the Comparable module, so all methods from there and in addition != are available.
SemverCheck::Compare.new("1.2.3") < SemverCheck::Compare.new("1.2.4") # true
SemverCheck::Compare.new("1.2.3") > SemverCheck::Compare.new("1.2.2") # true
SemverCheck::Compare.new("1.2.3") <= SemverCheck::Compare.new("1.2.3") # true
SemverCheck::Compare.new("1.2.3") >= SemverCheck::Compare.new("1.2.3") # true
# works also with prerelease
SemverCheck::Compare.new("1.2.3-alpha") < SemverCheck::Compare.new("1.2.3-beta") # true
SemverCheck::Compare.new("1.2.3-alpha.2") > SemverCheck::Compare.new("1.2.3-alpha.1") # trueYou get the idea. If you wanna know more check out the test/test_compare.rb file.
