Rubyrator
Python like method decorators for Ruby.
Installation
gem install rubyrator
Usage
Extend Rubyrator in a class where you want to use it, and then stick decorate :decorator_method_name before your method declaration to decorate the method.
You can set multiple decorators for your methods.
class Html
extend Rubyrator
def bold(dec_args, orig, *args, &block)
"<b>" + orig.call(*args, &block) + "</b>"
end
def italic(dec_args, orig, *args, &block)
"<i>" + orig.call(*args, &block) + "</i>"
end
decorate :bold
decorate :italic
def text(text)
text
end
end
puts Html.new.text("decorate me please") # => "<b><i>decorate me please</i></b>"You can add parameters to your decorator methods. Just pass them after a decorator method name, separated by the comma.
class Spamer
extend Rubyrator
def retry(dec_args, orig, *args, &block)
retry_num = dec_args[0]
retry_num.times do
orig.call(*args, &block)
end
end
decorate :retry, 3
def spam(spam_message)
print spam_message
end
end
Spamer.new.spam("spam") # => "spamspamspam"License
