Takes a String containing a constant name, and returns the canonical path of the constant (i.e. where it's defined, even if it's accessed differently.). If the constant does not exist, a NameError is thrown. @param constant_name (String) the constant name @return (Object) the actual named constant.
# File lib/octiron/support/constantize.rb, line 21 def constantize(constant_name) names = constant_name.split('::') # Trigger a built-in NameError exception including the ill-formed # constant in the message. if names.empty? Object.const_get(constant_name, false) end # Remove the first blank element in case of '::ClassName' notation. if names.size > 1 && names.first.empty? names.shift end # Note: this would be much more complex in Ruby < 1.9.3, so yay for not # bothering to support these! return names.inject(Object) do |constant, name| next constant.const_get(name) end end
