1.2.0 2019-10-06

Changed

• Dry::Types.[] used to work with classes, now it's deprecated (flash-gordon)

Fixed

• Bug with using a Bool-named struct as a schema key (flash-gordon)
• A bunch of issues related to using meta on complex types (flash-gordon)
• Types.Constructor(...) returns a Types::Array as it should (flash-gordon)

Added

• Optional::Params types that coerce empty strings to nil (flash-gordon)

  Dry::Types['optional.params.integer'].('') # => nil
  Dry::Types['optional.params.integer'].('140') # => 140
  Dry::Types['optional.params.integer'].('asd') # => exception!

  Keep in mind, Dry::Types['optional.params.integer'] and Dry::Types['params.integer'].optional are not the same, the latter doesn't handle empty strings.

• Predicate inferrer was ported from dry-schema (authored by solnic)

  require 'dry/types/predicate_inferrer'
  Dry::Types::PredicateInferrer.new[Types::String]
  # => [:str?]
  Dry::Types::PredicateInferrer.new[Types::String | Types::Integer]
  # => [[[:str?], [:int?]]]

  Note that the API of the predicate inferrer can change in the stable version, it's dictated by the needs of dry-schema so it should be considered as semi-stable. If you depend on it, write specs covering the desired behavior. Another option is copy-and-paste the whole thing to your project.

• Primitive inferrer was ported from dry-schema (authored by solnic)

  require 'dry/types/primitive_inferrer'
  Dry::Types::PrimitiveInferrer.new[Types::String]
  # => [String]
  Dry::Types::PrimitiveInferrer.new[Types::String | Types::Integer]
  # => [String, Integer]
  Dry::Types::PrimitiveInferrer.new[Types::String.optional]
  # => [NilClass, String]

  The primitive inferrer should be stable by now, you can rely on it.

• The monads extension adds Dry::Types::Result#to_monad. This makes it compatible with do notation from dry-monads. Load it with Dry::Types.load_extensions(:monads) (skryukov)

  Types = Dry.Types
  Dry::Types.load_extensions(:monads)
  
  class AddTen
    include Dry::Monads[:result, :do]
  
    def call(input)
      integer = yield Types::Coercible::Integer.try(input)
  
      Success(integer + 10)
    end
  end
