why's (poignant) Guide to Ruby, sometimes calledw(p)GtR or just "the poignant guide", is an introductory book to theRuby programming language,[1] written bywhy the lucky stiff. The book is distributed under theCreative Commons Attribution-ShareAlike license.

The book is unusual among programming books in that it includes much strange humor and many narrative side tracks which are sometimes completely unrelated to the topic. Many motifs have become inside jokes in the Ruby community, such as references to the words "chunky bacon". The book includes many characters which have become popular as well, particularly the cartoonfoxes andTrady Blix, a large black feline friend of why's, who acts as a guide to the foxes (and occasionally teaches them some Ruby).

The book is published inHTML andPDF. Chapter three was reprinted inThe Best Software Writing I: Selected and Introduced byJoel Spolsky (Apress, 2005).
