dry-types 1.9.0

v1.9.0

on Ruby Gems

Added

• params.* with .optional can now handle empty strings consistently with optional.params.* by returning nil instead of raising an error. (@baweaver in #487, @flash-gordon in #490)

  This behavior is not enabled by default because it's a breaking change. Set Dry::Types.use_namespaced_optionals(true) to enable it.

  Dry::Types["params.integer"].optional.("") # => CoercionError
  # Activate namespaced optionals
  Dry::Types.use_namespaced_optionals true
  Dry::Types["params.integer"].optional.("") # => nil

Changed

• Require Ruby 3.2 or later.
• Support bigdecimal version 4.0 as well as 3.0, improving compatibility with other gems that require 4.0 only. (@rus-max in #492)
• Improve sum type error handling documentation. (@baweaver in #486)

Fixed

• Fix Constructor#primitive? delegation for sum types. (@baweaver in #484)

  This now works without error:

  a = Types::String.constrained(size: 2) | Types::Hash
  b = Types::String.constrained(size: 1) | Types::Hash
  
  c = (a.constructor { |x| x.is_a?(Hash) ? x : x.downcase }) |
      (b.constructor { |x| x.is_a?(Hash) ? x : x.upcase })

• Fix Sum type to_s with Dry::Struct types. (@baweaver in #485)

  This now works without error:

  class A < Dry::Struct; end
  class B < Dry::Struct; end
  
  (A | B).to_s
