The tests for the Sieve of Eratosthenes snippets.

Generate prime numbers below some limit. This snippet incorporates some DSL like keywords to describe the prime algorithm.

Generate prime numbers below some limit. This snippet uses groovy categories to locate the appropriate methods in common classes.

Generate prime numbers blow some limit using the Sieve of Eratosthenes algorithm. This snippet uses some object abstractions to simplify the algorithm.

A possible implementation of the Sieve of Eratosthenes for generating prime numbers below some limit.

Conway's Game of Life - a solution for GroovyQuiz.com. You can download all of the sources and an executable jar.

Try to create a DSL for a finite state machine.

/**
* GOAL: Write a quick-and-dirty DSL in Groovy that emulates Bruce Tate's
* example "acts_as_statemachine" Ruby code at
* http://www-128.ibm.com/developerworks/java/library/j-cb03137/index.html,
* within 20 minutes or less (i.e. steer clear of MOP-magic engineering ;).

Using the SwingX JXMapViewer and using a special tile factory to retrieve Google Maps tiles, from a Groovy SwingBuilder.

This is an example from practice. The domain is a whater flow messure system. I wrote a blog entry where I fully described the evolution of this class - in german.

A GroovyClassLoader demonstration. The given domain is a german water flow meter system; I think, you shouldn't be able to understand the domain, but you should be able to understand, how to load a Groovy class in Java via a GroovyClassLoader.

Recursively iterate over folders and files to check for differences.

Using a JGroups ReplicatedHashtable from Groovy

Sudoku solver in Groovy.

SQL-like DSL for finding classes and methods

if you use the same buildfiles on your local codebase and your continuous integration buildserver, the if-attribute for ant's targets comes in handy...

for this ant buildfile snippet to only create+publish javadoc when executed on the buildserver, the buildserver only has to set the referred system property, e.g. on its startup by using a Java D-option "-Dcontinuous.build=true" ...
