Rosie Pattern Language

Modern text pattern matching to replace regex


The language reference contains some representative snippets that demonstrate Rosie’s unique features, and you might also like to look through the source code for Rosie’s standard library modules such as the date-parsing module.

Examples of Rosie v0.99, as well as some blog posts and Tech Talks, may be found on IBM developerWorks Open.

There were some changes when Rosie v1.0.0 was released, so please be aware the the IBM content may not match exactly what Rosie looks like today.
