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.
The document provides an overview of Griffon and its key concepts including views, models, and controllers. It discusses how Griffon uses SwingBuilder to define views, how models can be bound to views, and how controllers link models and views to handle user interactions. Code samples are provided to illustrate Griffon concepts like defining views, binding models to views, validation, and basic controller usage.
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.
The document discusses using GroovyConsole to run Groovy scripts and provides an interactive shell for Groovy. GroovyConsole allows adding custom menus and running code before and after script execution. It can be run from the command line with Java or by calling methods on the GroovyConsole class. The document also provides examples of running GroovyConsole on Jenkins and using MoteConsole as alternatives.
The document provides an overview of Groovy and Java code examples for performing common tasks like printing "Hello World", reading files, making web requests, using strings, importing packages, and using Swing/SwingBuilder for GUIs. It also shows examples of using Groovy with Java libraries for Excel files, Ant, and JSON. Additional sections cover parallel processing with GPars, contract programming with GContracts, method chaining, Grails basics, and Gaelyk controllers and views.
The document discusses Jenkins, an open source automation server. It provides links to Jenkins resources including its website and documentation on extending Jenkins. It also provides instructions on creating a Jenkins plugin using Maven and includes examples of plugins for adding a Twitter widget and servlet filter.
This document discusses using Groovy with Jenkins for continuous integration. It describes how to install Groovy on Jenkins, use Groovy scripts for initialization and through the Jenkins CLI, and leverage Groovy features like Grape for dependencies. Examples are given of initializing Jenkins, running scripts against it from the CLI or Groovy shell, and developing Groovy-based plugins. Benefits highlighted include Groovy's Java interoperability and how it enables dynamic Jenkins configurations and automation through scripts.
This document contains links and code snippets related to Groovy and GitHub Gists. It includes examples of using Groovy for tasks like playing MIDI notes, generating musical scores, adding nodes to a Jenkins server, and calculating factorials in different styles from a newbie to an expert programmer. The document also references a Greasemonkey script for running a Groovy web console in Firefox.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against developing mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
