About this Fork

The original author of this book is out of touch for years. I've modified the code to make it work with ruby 2.0.0. To preview it locally:

Read Ruby

Read Ruby is a book I’m writing about Ruby 1.9.2. It’s in a very rough state, but the latest version can always be viewed at ruby.runpaint.org.

Text and images are licensed under a Creative Commons license. Suggestions and issue reports are welcomed via the Issue Tracker.

Fork the GitHub repository, make commits and do pull requests.

To generate the book, you'll need:

Ruby 1.9.2 (or 1.9 trunk), which can be installed via rvm.
xsltproc (Available in an eponymous package on Debian and her derivatives).
The gems coderay, h5-min, nokogiri, sinatra, and w3c_validators. If you have the bundler gem installed, you can install the lot by executing bundle install in the repository root.
To validate the DocBook sources you'll need xmllint (packaged as libxml2-utils on Debian et al.) and/or oNVDL. (Validation will be skipped if these programs aren’t installed).
gzip for compressing HTML/CSS/JS. Installed by default on most systems.
