Although I have over a dozen Ruby books (and still do not master the
language) I try to make frequent use of the online documentation, rdoc,
located at: http://www.ruby-doc.org/core/.
However, I was searching the *rdoc* for a method I new existed by reading "*The
Ruby Way* - Second Edition By: Hal" but could not find it. The method was *
find_all* which is part of *Array* class. I then looked a bit further and
noticed that a sizable number of methods for the same class are not found at
Since carrying books is a bit difficult a time, is there a definitive site,
book, or whatever where I can find all the docs for a given release of Ruby?
