RBI provides a Ruby API to compose Ruby interface files consumed by Sorbet.

Add this line to your application's Gemfile:

gem 'rbi'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rbi

require "rbi"
rbi = RBI::File.new(strictness: "carview.php?tsp=true") do |file|
  file << RBI::Module.new("Foo") do |mod|
    mod << RBI::Method.new("foo")
  end
end
puts rbi.string

will produce:

# typed: true
module Foo
  def foo; end
end

• RBI generation API
• RBI parsing with Whitequark
• RBI formatting
• RBI validation
• RBI merging

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

This repo uses itself (rbi) to retrieve and generate gem RBIs. You can run dev rbi to update local gem RBIs with RBIs from the central repo.
