Wicked Good Ruby 2013 - Writing DSL's with Parslet by Jason Garber

A well-designed DSL improves programmer productivity and communication with domain experts. The Ruby community has produced a number of very popular external DSLs--Coffeescript, HAML, SASS, and Cucumber to name a few. Parslet makes it easy to write these kinds of DSLs in pure R ou'll learn the basics, feel out the limitations of several approaches and find some common solutions. In no time, you'll have the power to make a great new DSL, slurp in obscure file formats, modify or fork other people's grammars (like Gherkin, TOML, or JSON), or even write your own programming language!
