Description:

ParseTree allows taking any Ruby code and parsing it into an AST. This allows for two types of tools:

1. Code analysis
2. Custom DSL

We'll go through the power of the SexpProcessor class included with ParseTree and how they are made. We'll look at flog, ambition, and roodi and see what they offer us as Ruby developers. Finally, I'll turn our attention to see what the future has to offer with Ruby 1.9.1 and the included Ripper library.
