Dynamic languages such as JRuby, Groovy, and Jython are increasingly playing an important role in the web these days. The associated frameworks such as Rails, Grails, and Django are gaining importance because of the agility provided by them. This session gives an overview of various Dynamic Languages and associated Web frameworks that can be used on the GlassFish project.
While some find Groovy language still in its infancy, others know that there is now Groovy++ and are all eyes and ears on what “++” of the language is going to bring, which itself was touted by some as Java++.
The session looks at the fundamentals of Scala with examples to highlight its unique features like case classes and pattern matching, for comprehensions, traits, functions as values and others. It also looks at Scala’s support for writing internal as well as external DSLs.
Spring’s support for scripting languages allows you to extend your Java applications with beans defined in a scripting language, such as Groovy. Spring container transparently instantiates, configure and dependency injects the beans across these supported languages. Beans defined in a scripting language like Groovy come with some handy advantages such as ability to “refresh” the already loaded Groovy classes when the underlying source files change.
Python scripting language use has increased by 45% since Spring 2008 according the an Evans Data North American Development Survey. Only 13% of developers used Python before Google announced its App Engine platform in Spring 2008, which at the time only supported Python, but that number has increased to 20.3% today. Other scripting language use remained relatively constant, with only small gains or losses in popularity among languages such as Ruby, PHP, Perl and Actionscript.
Noop is a new language that attempts to blend the best lessons of languages old and new, while syntactically encouraging industry best-practices and discouraging the worst offenses. Noop is initially targeted to run on the Java Virtual Machine, is what the Noop site says.
