Version 1.5.5 of Groovy has been released. This is a bug fix release with no major new functionality, however, improvements made to Groovyc (the groovy compiler) for 1.6 have been backported to the 1.5.x branch resulting in a compiler that is now three to five times faster. Check out the release notes for more information.

How easy is it to provide JSON/XML data for an Ajax call in a Grails web-app? The Agile Ajax blog has a quick tutorial showing that providing data to your Ajax applications could hardly be easier!

One of my favorite features of Groovy is the safe navigation operator. As a Java developer by day (heroic blogger by night?), I spend a good amount of time fixing bugs revolving around null pointer exceptions. With Groovy, the ? operator saves you from constantly having to check for null. Andrew Glover has a good example of Defensive Programming with Groovy over at The Disco Blog today.

Two articles today in the “What I like about…” category. The first one is from Jorge Lugo on what he likes about Groovy. Nice write up pointing out some of the niceties that Groovy gives you over Java (I especially like the safe dereferencing - The Groovy docs call this Safe Navigation).

The second article is from Debasish Ghosh on why he likes Scala’s lexically scoped open classes. Enjoy!

Andrew Glover over at The Disco Blog wrote today about Metaprogramming with Groovy. The ability to add proprietary or domain-specific behavior to objects is a great feature of JavaScript and Ruby and one that I use often at work. Mr. Glover explains the technique and gives an example of adding behavior to a class at runtime with Groovy.

Less than a week after releasing version 1.5.2, the Groovy team has announced 1.5.3. Apparently, 1.5.2 contained some regression bugs that have since been worked out. This is a minor bug-fix only release.

In other Groovy news, The Server Side has an interview with Dierk König regarding Canoo and testing with Groovy.

Groovy 1.5.2 was released today. This is being called a bug-fix release, but there are a few new features as well. Check out the announcement here and the release notes here.

Guillaume Laforge, project lead for Groovy, has a new article on Groovy Zone called “From Java to Groovy in a Few Easy Steps“. It’s a nice introduction for the Java developer whom is curious about Groovy and would like to get their feet wet.

Michael Kimsal has just posted the second part of a series [Part 1, Part 2] entitled “Grails for PHP developers”. They are a bit basic, but highlight where a PHP developer could get hung up writing a Grails application. For a more in-depth introduction to Grails, check out “Mastering Grails: Build your first Grails application” by Scott Davis.
