Creating Groovy DSLs that Developers can Actually Use

In this presentation, Guillaume, Paul, and Andrew will show you how to leverage Groovy to build a Domain-Specific Language (DSL) used to control a rover on Mars! Various metaprogramming techniques and integration mechanisms will be demonstrated. But the language itself is only the first part of the story. Developers cannot be expected to properly use a DSL without first-class IDE support and documentation.

The presentation will start by building the DSL from scratch, using the power of Groovy to create a concise and readable mini-language, and showing how to secure its integration. The second part of the presentation will demonstrate how to integrate the DSL into Groovy-Eclipse with custom content assist, navigation, searching, and inline documentation.

Functional Groovy

Groovy doesn't claim to be a fully-fledged functional programming language but it does provide the Java or Groovy developer with a whole toolbox of features for doing functional style programs. This talk looks at the key Groovy features which support a functional style. Topics covered include using closures, currying and partial evaluation, closure composition, useful functional-centric AST macros, useful functional-centric runtime meta-programming tricks, trampolining, using Java functional libraries, immutable data structures, lazy and infinite lists, using Groovy 2's static typing and approaches for moving beyond Java's type system.

There are many advantages to using a functional style in your programs. Learn what can be done to leverage functional style while retaining many of the productivity gains of the Groovy programming language.

Writing your own Groovy 2.0 module

Learn about the modularization features in Groovy 2.0 including everything you need to know to write and use your own modules.

Provides an overview of the modularization (m12n) mechanism in Groovy 2.0 including: * The different parts of m12n. * The use of m12n features within the standard distribution. * Turning standard features on and off. * How to write and use your own module (illustrated by making modules for some existing open source libraries). * m12n futures (what other features are planned in future releases)
