Support for multiple rubies? about appraisal

[adrianthedev]

I was just about to post the same question.

In https://github.com/avo-hq/avo/ we want to test the package against a few ruby 2.x versions and 3.0. We are using the https://github.com/ddnexus/pagy gem and they use different versions for ruby 2.x and 3.x.

Thank you for your support!

Not sure how this would work. I am on 2.7 and when I run this script it raises an error that it can't install pagy 4 on ruby <2.7 (the host's ruby).

Just as a clarification pagy 3 is for ruby <3.x and pagy 4 for ruby >=3.0.

["6.0", "6.1"].each do |rails_version|
  appraise "rails-#{rails_version}-ruby-2.6" do
    gem "rails", "~> #{rails_version}.0"
  end

  appraise "rails-#{rails_version}-ruby-2.7" do
    gem "rails", "~> #{rails_version}.0"
  end

  appraise "rails-#{rails_version}-ruby-3.0" do
    ruby "3.0"

    gem "rails", "~> #{rails_version}.0"
    gem "pagy", "~> 4.0"
  end
end

@etagwerker you can also try #176

My immediate feeling is that #176 would be the right way to do this (I'm going to look at this once I fix several bundler compatibility issues we currently have as I write this).

On projects with multiple Rubies and Appraisal, I typically do this instead: https://github.com/thoughtbot/administrate/blob/main/.circleci/config.yml (see thoughtbot/administrate#1932 for using GitHub Actions instead)

So unlike in your examples, we're running a different Ruby version per container and keep the same Appraisal per Ruby version.

I'm going to close this as it's not moved along in a long time — and hopefully #176 if good enough as a solution for most cases.
