Modern Groovy DSLs
06 July 2016 - David Clark
Abstract
Making DSL's in groovy has changed a lot since Groovy 1.0. Back then it was
all about what you could do dynamically: implementing propertyMissing and
methodMissing, adding operator overloading, using named parameters, and
leaving off semi-colons. All of those are still valid groovy, but Groovy
has added a lot of features to make DSL's safer, faster, and easier to use.
These are features like the @DelegatesTo annotation, script base classes,
type checking extensions, extension modules, and the old standby, closure
delegation.
We'll also talk about what makes a good DSL and when you want to implement
one.
Bio
David Clark is a software engineer working for ResearchNow. His current
responsibilities are 1) developing tools for improving database deployment
speed and accuracy and 2) Improving and simplifying data access in
ResearchNow applications. Both make heavy use of Groovy. In the past he
worked in Telecommunications and the financial/banking worlds using Java
technologies. He has used Groovy since the 1.0 release in 2007.
