Changed

• Improved error messages were rolled back, they created an implicit dependency on dry-types (@flash-gordon)

Compare v3.1.0...v3.1.1

v3.1.0

• Improved error messages on type mismatch (@swerling)
• [BREAKING] Minimal supported Ruby version is 2.7 (@flash-gordon)

Compare v3.0.4...v3.1.0

v3.0.4

Fixed

• Arity check for lambdas used for coercion (@flash-gordon)

Compare v3.0.3...v3.0.4

Fix underscored names of param/option-s

v3.0.1

Fix validation of underscored names

Support of wrapped and nested types

class Test
  extend Dry::Initializer

  # Wrapped type
  option :foo, [proc(&:to_s)]

  # Nested type
  option :bar do
    option :baz, proc(&:to_s)
  end

  # Both wrapped and nested type
  option :qux, [] do
    option :sax, proc(&:to_s)
  end
end

test = Test.new foo: 4, bar: { baz: 5 }, qux: { sax: 6 }

# Wrapped type wraps a coerced value to array
test.foo # => ["4"]

# Nested type builds the nested structure
test.bar.baz # => "5"

# Their composition wraps the result of nesting
test.qux.first.sax # => 6

Fix coercion of `nil`

v2.6.0

Bump v2.6.0

Switch operands to test for undefined attrs

v2.5.0

Bump v.2.5.0

Add dispatchers for extending syntax

v2.4.0

Bump v2.4.0

Type coercer can take second argument for the initialized instance

This allows to wrap assigned value to the object that refers back
to the initializer instance. More verbose example:

class Location < String
  attr_reader :parameter # refers back to its parameter

  def initialize(name, parameter)
    super(name)
    @parameter = parameter
  end
end

class Parameter
  extend Dry::Initializer
  param :name
  param :location, ->(value, param) { Location.new(value, param) }
end

offset = Parameter.new "offset", location: "query"
offset.name     # => "offset"
offset.location # => "query"
offset.location.parameter == offset # true

Add option `:desc` to param/option, and `#inch` to the initializer's config
