nonnax -

What's "tap"?:

csspretty.rb:2: undefined method `tap' for #<String:0x21fb4c>
(NoMethodError)

Thanks,

You could install the ruby facets gem. Or you could implement the tap
method itself (from facets):

def tap(&b)
if block_given?
b.arity == 1 ? yield(self) : instance_eval(&b)
end
self
end

In the facets gem, they implemented that in the Kernel module.

And here's an article on "tap": http://www.infoq.com/news/2008/02/tap-method-ruby19

Object#tap is also implemented in ruby 1.8.7
