Add attribute readers for unknown attributes
default behavior remains unchanged
Unknown params and options are ignored but stored in their own attr_reader
class Test::Foo
extend Dry::Initializer
param :foo
param :bar, optional: true
end
foo = Test::Foo.new(1, 2, 3, 4)
foo.__dry_initializer_unknown_params__ # => [3, 4]
class Test::Foo
extend Dry::Initializer
option :foo
options :bar, optional: true
end
foo = Test::Foo.new(foo: 1, bar: 2, fizz: 3, buzz: 4)
foo.__dry_initializer_unknown_options__ # => {fizz: 3, buzz: 4}
rest params and rest options names are configurable
class Test::Foo
extend Dry::Initializer
param :foo
param :bar, optional: true
rest_param :unknown_params
end
foo = Test::Foo.new(1, 2, 3, 4)
foo.unknown_params # => [3, 4]
class Test::Foo
extend Dry::Initializer
option :foo
options :bar, optional: true
rest_options :unknown_options
end
foo = Test::Foo.new(foo: 1, bar: 2, fizz: 3, buzz: 4)
foo.unknown_options # => {fizz: 3, buzz: 4}
rest params and rest options can be turned off for strict mode
This adds support for strict checking of params and options: #68
class Test::Foo
extend Dry::Initializer
param :foo
param :bar, optional: true
rest_param false
end
Test::Foo.new(1, 2, 3, 4) => raises ArgumentError
class Test::Foo
extend Dry::Initializer
option :foo
options :bar, optional: true
rest_options :unknown_options
end
Test::Foo.new(foo: 1, bar: 2, fizz: 3, buzz: 4) # raises ArgumentError
Rubocop linting is needed but I'm loath to do that first as the class/module nesting changes lead to every line of the files getting whitespace changes that would obscure the code really being touched.
