deprecate

deprecate :foo deprecate bar: ‘message’ deprecate :foo, :bar, baz: ‘warning!’, qux: ‘gone!’

You can also use custom deprecator instance:

deprecate :foo, deprecator: MyLib::Deprecator.new deprecate :foo, bar: “warning!”, deprecator: MyLib::Deprecator.new

Custom deprecators must respond to deprecation_warning(deprecated_method_name, message, caller_backtrace) method where you can implement your custom warning behavior.

class MyLib::Deprecator

def deprecation_warning(deprecated_method_name, message, caller_backtrace = nil)
   message = "#{deprecated_method_name} is deprecated and will be removed from MyLibrary | #{message}"
   Kernel.warn message
end

end
