[ANN] Gaelyk 1.0 is here, the lightweight Groovy toolkit for Google App Engine

[Guillaume Laforge]

Hi all,

I'm very happy to announce the final release of Gaelyk 1.0, the lightweight Groovy toolkit for Google App Engine!

It took some time to get to 1.0, but it's now here, with the key feature I've been missing since the beginning of the project, in particular the Query DSL which allows you to write queries like this one:

def latestArticles = datastore.execute {

select all from articles

sort desc by dateCreated

where author == params.author

limit 10

}

If you want to learn more about this lightweight framework, head over to:

http://gaelyk.appspot.com/

You can learn everything through the tutorial:

And download the JAR or the template project here:

Should you want to ask questions on the Google Groups, get involved in the community, participate in the development of this Open Source project, have a look at our community page:

http://gaelyk.appspot.com/community

This release wouldn't have been possible with all the great contributions of you all, your pull requests on GitHub, your Gradle plugins, your bug reports, your questions on the Google Group, etc. So I'd like to tell you all a big thank you for all your work and contributions. They were very much appreciated, and keep them coming!

The change log:

• GAE SDK updated to 1.5.2 and Groovy to 1.8.1
• Introduction of a Query DSL for creating SQL-like queries against the datastore
• Updated template project with a Gradle build, the usage of Gradle GAE / Gaelyk plugins, and the support of Spock for testing Groovlets
• Introduction of the plugins page in the Gaelyk website, for referencing known plugins
• By annotating classes with GaelykBindings, the same services and variables are injected in your classes as properties, as the ones which are injected in Groovlets and templates
• The validation closures of the routes in your URL mapping have access to the request, so you can validate a URL depending on what's in your request (attribute, session, etc.)
• Added a DSLD file (DSL descriptor) for Eclipse for easing code-completion and navigation
• Added a get() method on Key, as well as on lists of keys
• Ability to convert lists to Keys
• Added two encoded string and key conversion utilities
• Additional datastore.get() methods to retrieve entities by their keys more concisely
• Problems with the recent XMPP support fixed
• Fixed inability to access the various services and variables from within binding/before/after blocks in plugin descriptors

Thanks a lot for your attention, and enjoy developing Groovy applications on Google App Engine!

Congratulations Guillaume, and thanks for all the hard work!

[Kunal]

awesome... congratulations. I had been waiting for this announcement for long :)
Thanks Guillaume for all your hard work.

Great,
I will take the opportunity of the holidays to discover this framework.
Congratulations for your work!

In the template is it normal that the data insered is "bart" and the data searched is "marco". The test fails if we don't modify it.
The 'dataStoreGroovlet.groovy' file seems to be missing too

Looks like I messed the template a bit :-)

I've restored the sample groovlet, and fixed the test, and pushed those changes to GitHub, sorry for the inconvenience.

I'll certainly release a point release sometime soon, in case people find some bugs, and the template will be fixed in there, but if you're impatient, you can pick up the two files (the test and the groovlet) from GitHub.

Thanks a lot, 

I'm just discovering Gaelik but I already love it.

I less than one day I am already able to deploy a mini blog engine on GAE.

It's really  simple, powerfull and elegant! I

Super, I'm just starting with Groovy and Gaelyk and was using Maven
for the build so far. I'll definitly switch to Gradle to learn it too.
I was also missing examples to the blog engine is very appreciated to
just read some code.
Thanks !

A good example I used to start : http://globalgateway.wordpress.com/2010/10/21/simple-crud-with-gaelyk/ (both post and comments are interesting)
