How to get only class name without namespace

ruby namespaces

If you are using Rails, you can actually use the demodulize method on the String class.http://apidock.com/rails/String/demodulize

bar.class.name.demodulize

ruby namespaces

The canonical way to do this is to invoke Object#class and Module#name. For example:

bar.class.name.split('::').last#=> "Bar"

ruby namespaces

I believe this would work fine too:

module Foo  class Bar  endendbar = Foo::Bar.newprint bar.class.to_s.split('::').last

This would result in

Bar

I also believe it would be a bit faster than the regular expression evaluation, but I'm not sure about this and I haven't performed a benchmark.
