RequiredRubyVersion

[marcandre]

The Gemspec/RequiredRubyVersion cop checks that spec.required_ruby_version= (if present) corresponds to TargetRubyVersion.

That's good.

I'd like a more basic check: that required_ruby_version is there at all. I believe that it should be an accepted community standard to have it; there is no valid reason not to have a required_ruby_version specified that I can think of.

I opened an rfc about that, but it would probably take time before this is accepted / implemented / released and mostly updated... A Rubocop might make things faster.

In case there is a .travis.yml file, it would be nice to check it correponds too.

1. How does a cop making required_ruby_version mandatory sound?

2. If that's a go, should it be a different cop?

3. What about .travis.yml check?

I like the idea. I can't come up with a good reason why a gem shouldn't specify some required Ruby version.

Should this gets closed?
