You can get Ruby from ftp://ftp.netlab.co.jp/pub/lang/ruby
from the mirror sites listed on page 526 in Appendix
C. There you will find the latest
stable release, as well as various development releases.
You'll always find source code releases of Ruby; you may also find
prebuilt binaries for Windows or other operating systems (like
the binary distribution of Ruby for Windows at
Sidebar: The Very Latest Ruby
For those who just have to be on the very latest, hot-off-the-press and
untested cutting edge (as we were while writing this book),
you can get development versions straight from the developers'
The Ruby developers use CVS (Concurrent Version System, freely
available from https://www.cvshome.com) as their revision control
system. You can check files out as an anonymous user from their
archive by executing the following CVS commands:
% cvs -d :pserver:[email protected]jp:/home/cvs
(Logging in to [email protected])
CVS password: guest
% cvs -d :pserver:[email protected]:/home/cvs
The complete source code tree, just as the developers last left it,
will now be copied to a ``ruby'' subdirectory on your machine,
updating your local source tree from a repository on the other side of
the world. Isn't it a great time to be alive?
