Preface: Ruby provides an automatic constant called DATA, which is an IO object that references all text in the current file under an __END__ token. I find it convenient to use the __END__ area to store all sorts of stuff, rather than have to worry about distributing separate files.The problem: The DATA constant is determined from whatever ruby believes $0 to be. It doesn't work inside of other required libraries, so you'll see stuff like this all the time: END = File.open( __FILE__ ).read.split( /^__END__/, 2 ).last It works, but it's more work than I want to do.A workaround: Chunker solves this by parsing __END__ tokens for you, and making it available in the form of a 'DATA_END' constant. It installs this constant into the class that includes Chunker, so you can use it again and again, assuming you use a different file for each class. It also automatically parses out other things that look like tokens, so you can easily have multiple, distinct documents all embedded into the __END__ block.Usage: There is no direct interface to Chunker. Just include it from a class to have that file's __END__ data blocks magically become DATA_* IO constants within that class.Example: This produces the string "Yep.\n". require 'chunker' class Foom include Chunker end puts Foom.new.class.const_get( :DATA_WICKED ).read __END__ Stuff in the END block! __WOW__ Ultimate success! __WICKED__ Yep.
