Ruby script to translate Objective-C method calls into MacRuby

Objective-C to MacRuby method translate

#!/usr/bin/env ruby
# Translates an objective C method call on the pasteboard,
# as copied from the docs, into MacRuby syntax, placing it
# back on the pasteboard.

# @example
#     '+ (NSColor *)colorWithCalibratedRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha'
#  =>  'colorWithCalibratedRed(red, green:green, blue:blue, alpha:alpha)'
