Is there a clean way to extract the version string from a .gemspec file?

  • 0

Is there a clean way to extract the version string from a .gemspec file? (The gem is not yet installed)

e.g. somethingcool.gemspec is

Gem::Specification.new do |s|
  s.name = "somethingcool"
  s.version = "1.2.3"
  ... etc ...
end

I want to extract “1.2.3”.

I could grep it out but there must be a better way.

    require "rubygems"
    
    spec = Gem::Specification::load("example.gemspec")
    puts spec.version
