Ruby magic

Posted on Tuesday January 23, 2007 by Julian I. Kamil

These are links to excellent articles from eigenclass.org on some magic that can be performed with Ruby:

• Inspecting a live Ruby process, easier if you cheat

This shows how to turn the GNU debugger gdb into a Ruby interpreter, making it useful for debugging Ruby code.

• Using DL to unfreeze objects

This shows how to use the Ruby/DL extension to manipulate the internals of Ruby objects. Needless to say, proceed with caution!

• A simple full-text search engine in 200 lines of Ruby

As the title says, a walk-through of the implementation of a single-term, extensible, and fast search engine in just a few lines of code.

These are great reads for those who want to get to know the naked Ruby better.
