Kiyotaka Oku

 

The document discusses Groovy, a dynamic language for the Java Virtual Machine. It has features from Python, Ruby, and Smalltalk, but uses Java-like syntax. Examples show Hello World programs in Java and Groovy. Later sections discuss Grails, a web framework for Groovy, and G*Magazine, a publication about Groovy. The document contains code samples for defining a Book domain class in Grails, implementing services with Spring Security annotations, writing Spock specifications, and Geb tests using the Page Object pattern.

Groovy is a dynamic programming language for the Java Virtual Machine (JVM) that includes features from languages like Python, Ruby, and Smalltalk. It uses syntax similar to Java but allows for dynamic features not available in Java. Hello World programs can be written in one line of Groovy code instead of the typical Java class and method structure. Groovy code can also be written like Java code for interoperability.

This document discusses using Groovy transformations like @EqualsAndHashCode to add functionality to classes at compile time through AST transformations. It provides an example of adding equals() and hashCode() methods to a Person class using the @EqualsAndHashCode transformation. It also shows how to create a customized Groovy shell that applies transformations like @ThreadInterrupt by configuring the CompilerConfiguration with ASTTransformationCustomizers.
