Source Code, PDF and Presentation about Groovy 1.8 from JFall 2011

Mr. Haki (of “Groovy Goodness” fame) has posted slides and code from a Groovy 1.8 presentation of his at JFall 2011 (an annual conference put on by the NLJUG). There is also “an extensive PDF with content” (1.8 recipes, similar to his Groovy Goodness posts). The whole of it is on GitHub.

Groovy Static Type Checker: Status Update

For the last month, Cédric Champeau has been employed at SpringSource and working on Groovy. Among other things, he is working on a static type checker for Groovy. (As he puts it: “…the main goal of this project is to make the compiler grumpy, meaning it will complain where regular Groovy does not.”) This project has been discussed on the Groovy mailing list for some time now. The official (well, by Cédric) update, posted on the 3rd, goes into some detail on what is and is not dealt with, and in what manner, in Groovy’s “grumpy mode.”

Converting Groovy Maps To Query Strings

Ken Kousen has put up another classic ( ) “Stuff I’ve learned recently…” post (“Yesterday I was teaching a class on Groovy when I suddenly realized there was a simpler way to do something I’d been doing for years”), this time on converting a Groovy map to a query string for use in a RESTful web service.

Gaelyk Presentation At SpringOne2GX

Guillaume Laforge has posted the slides from his Gaelyk session at SpringOne 2GX.

Our sources tell us that Groovy and Grails people across the world have been conspiring together to make this week one with scarcely any Groovy news whatsoever. However, they were unable to counteract the powerful groovy forces that, left unattended, resulted in

SpringOne 2GX

Last month, which is to say “last week” (literally, “yesterday”), on the 25th, about 21 groovy Groovy and Grails experts got together with some Spring people for the third annual SpringOne 2GX. The attendees (and speakers) have started the review posts. These are currently available:

Glen Smith: “SpringOne2GX 2011 was one Groovy Show!”

“What a fantastic time we all had at SpringOne 2GX in Chicago over the last week. My head is jam packed full of information and I have so many new things to add to my list of cool Groovy tech to explore!”

Guillaume Laforge: “Groovy Domain-Specific Languages in Chicago”

“With my friend Paul King, we ran our Groovy Domain-Specific Languages talk again this year in Chicago, for the SpringOne2GX conference. I’ve uploaded the slides on Slideshare, and Paul has pushed the examples on Github.”

The Grails Podcast: “Episode 128: Groovy Grails BOF at SpringOne2GX”

“This episode is a live recording that was made at SpringOne2GX on the Wednesday night, so there’s about 50 or 60 Groovy and Grails guys hanging out, talking with the project leads and the core committers about all things Groovy and Grails.”

Griffon-ness

Andres Almiray, having already warned us that there was Griffon news to be coming up, has this week put up a couple of new posts on various Griffon-related topics:

Griffon: to SQL or NoSQL

A common question asked in the Griffon mailing list is: can GORM be used with Griffon? Sadly the answer is no, not yet. However this doesn’t mean there’s no persistence support for Griffon at all….

Griffon: hanging by a thread

Java Swing developers are well aware of the golden Swing Rule. Given that it’s so easy to break it we at Griffon try to make your life easier by sticking to conventions.…

There is more at his blog, which you should be reading anyway.

Six Ways To Become A Better Grails Programmer

Tomas Lin covers six ways in which Grails developers can take advantage of  many learning opportunities; half of them involve helping others learn.

SpringOne 2GX

The “premier Java event of 2011” — SpringOne2GX, put on by SpringSource and the excellent folks at No Fluff Just Stuff, begins today. Of course, you cannot sign up at this late hour, but I can at least taunt you with the schedule, to let you see exactly what you’re missing (don’t worry — I am sadly not attending it, either). Check back here next week; if any attendees get to posting about the conference afterwards, as Mr. Haki did with GR8Conf, I will try to let you know here.

“Groovy Goodness” by Mr. Haki is back

Mr. Haki has returned to his series on Groovy language features after a few months away. Many of the bits he discusses are new in Groovy 1.8, and all are worth the reading.

Patching bean-fields On 2.0.0.M2

The bean-fields plugin by Marc Palmer is messed up a bit in Grails 2.0 M2 by a breaking change in that release. This will not be an issue in RC1. In the meantime: Glen Smith explains how to resolve it with a simple modification to the taglib.

Groovy On GitHub

This summer, the Groovy team (with help from Matthew McCullough) moved Groovy’s source to GitHub. See the links in this post by Guillaume Laforge.
