Criar aplicações web, escrever shell scripts facilmente, escrever de forma concisa, criar casos de teste usando integração com JUnit, ou prototipar, nunca foi tão interessante.

Groovy trabalha de forma transparente com todos os objetos e bibliotecas Java existentes e compila diretamente para Java bytecode tanto no desenvolvimento de aplicações como no modo script.

Groovy fornece poder adicional :

  • conceitos de linguagem aprimorados
    • Suporte a closures - blocos de código reutilizáveis
    • Sintaxe nativa parar listas e mapas
    • Suporte ao padrão Gof Builder através na noção de builders
    • Operadores regex ao nível de sintaxe e sequências de escape
    • Suporte nativo a JavaBean
    • Sobrecarga de operadores  para simplificar o trabalho com Collections e Maps
    • Iteração polimórfica e autoboxing
    • Estensão da biblioteca padrão da Java através do GDK
  • características padrão úteis para aumentar a produtividade do desenvolvedor, tais como:
  • ótimos módulos criados pelo usuários
    • Grails : Groovy on rails para o fácil desenvolvimento de aplicações multi-camada
    • Gram : uma ferramenta do tipo xdoclet para processar marcações doclet tags ou anotações do Java 5
    • COM Scripting
    • GroovySWT : wrapper em torno do SWT, a biblioteca gráfica do Eclipse
    • GroovySOAP: acessando web services com Groovy
    • GSP : Groovy server pages
    • GSQL : acessando banco de dados com Groovy
    • Process : manipulando processos externos
    • XML-RPC : RPC (Remote Procedure Call) sobre HTTP realmente fácil
    • Jabber-RPC: RPC sobre sistemas de mensagens instantâneas baseadas em Jabber (incluindo o Google Talk)
    • GoogleDataSupport: use facilmente as APIs de dados do Google dentro doGroovy
    • GORM : Mapeamento Objeto-Relacional do Grails
    • Groovy Monkey: port do Eclipse Monkey para Groovy com algumas melhorias

Codifique com prazer!!!

Static compilation in the new Groovy 2.0 beta
The Groovy development team is pleased to announce the release of the last beta version in the 2.0.0 release cycle!

This version introduces two major enhancements: the @CompileStatic annotation (which enables static compilation of Groovy code) and support for invokedynamic (known as indy)!

If you already gave a try to the static type checker available in previous beta releases of Groovy 2.0, static compilation is a step further. Basically, replacing the @TypeChecked annotation with @CompileStatic, your code will be statically compiled.

Support for the new "invokedynamic" JVM instructions is also bundled into this distribution. However, as we must maintain binary compatibility with previous versions of Groovy and JDKs (especially, support for JDK 5 and 6), the indy-enabled version of Groovy is available in a separate jar. If you use Maven, Ivy or Gradle, the jar is available using the "indy" classifier. If you use the distribution zip, you will find two jars in a separate directory ("indy"), corresponding to groovy.jar and groovy-all.jar (for embedded version).

We strongly encourage you to test both static compilation (and type checking) and invoke dynamic support because this release is the last beta: the next Groovy version will be an RC with modularisation included. More than ever, we need beta testers!

You can download Groovy 2.0.0-beta-3 at the regular place: http://docs.codehaus.org/display/GROOVY/Download

For those who are interested in bug fixes since beta 2, you can read the release notes: http://jira.codehaus.org/secure/ReleaseNote.jspa?projectId=10242&version=18244

Thanks to all our contributors and all your feedback!

Less than a week for GR8Conf Call for Papers

GR8Conf are conferences about all the great technologies based on or using Groovy in a way or another. So in other words, that's the grooviest conference you can find, where developers and leads of all the famous Groovy-based projects deliver the latest news and updates about their projects. So be sure to come, learn with them, engage with the community, tell about your usage of those technologies (Grails, Gradle, Griffon, Spock, Gaelyk, etc.)

GR8Conf Europe and GR8Conf US have their Call for Paper still open, for less than a week. So if you haven't yet submitted your proposals, please hurry up!

We're looking forward to having you here!
