As far as I read on that site, it’s about $30 per book per year. If I
participated in writing an open source book about Ruby, I’d rather do
that for free (as in free beer [but I would accept being paid for it

Germany 2004: To boldly spy where no GESTAPO / STASI has spied before
Hi!
I think it is a good idea to illustrate how Ruby can be used as a

that generates HTML out of it. It is a quick hack but should give an
idea of how a more complex solution (including a couple of output
formats) could look like. For more take a look at the source of the

They are working out subscriptions. The initial $30 is for a first purchase.
That would make good sense to me.
(FWIW, those who have MacOS X already have PDF ‘print’ capabilities
from any application, so PDFs could be created from, say, HTML+CSS)

OpenOffice will export to PDF.
Also, there was an attempt at a community-driven Ruby book at
http://www.rubydoc.org/book.
Good writing is time-consuming, and hard to do well. A Ruby book,
unless its something along the lines of a cookbook or “Ruby Hacks,”
should have a consistent author’s voice and theme. If it purports to
teach people Ruby, then what is offered in the early chapters should lay
the foundation for more advanced and interesting topics later on.
I’ve worked on a few Wrox books where 8-to-12 writers were all pitching
in on different topics. While the books were constructed to have a
central theme, they often came off as a collection of magazine articles.
This can be useful, but I don’t think we need to think in terms of a
book in order to assemble a collection of tutorials.

IMHO the most sensible technology to use for a new collaborative Ruby book
would be WikiMedia. See http://www.wikibooks.org.
However, http://www.rubydoc.org/book/ is an existing collaborative Ruby
book. Why start another when you can help that?
These things just don’t tend to happen, for the reasons James mentioned:
difficult and time consuming.

docbook is an option. Is coughxmlcough but goes to pdf, html, or

Hi!
What about those who can’t read german? Should we send your site to
google to translate? Do you need someone to make an English version
of your example document?
Maybe you misunderstood something:
a) The example document is part of the message I sent and in English.
b) The class that does the HTML representation does not generate a
table of contents because that is a bit more involved.
c) The reference to the Ruby source of the German FAQ[1] is present
because it implements more - like a table of contents and a LaTeX
representation. That would have gone beyond the scope of a message
that is nothing but a suggestion of how something could be done.
d) I would have suggested the text even if it were written in Klingon
because the language uses does not have anything to do with the
layout. At least if the language fits into the usual typographic
scheme. The text could be in Turkish - it simply wouldn’t matter.

I don’t think that the actual format is very important. What is
needed?
Headlines of several levels
Paragraphs
italics, bold, typewriter
Preformatted text
Itemization
Enumeration
Description lists
Tables
Graphics
This can be done in HTML 3.2+, LaTeX, RTF and even in Ruby.
Yes, Ruby. The german edition of the comp.lang.ruby FAQ is a Ruby
script that generates HTML and LaTeX.
http://oss.erdfunkstelle.de/ruby/FAQ.rb
It may sound a bit strange but it was a proof of concept and it
works. All other representations are generated from the Ruby source.
