For all those us interested in groovy and JSON ... JSON will be becoming
even easier to use in Groovy ... Let's se what we can do about this or
for this in Sling ;-) [Besides upgrading to 1.8 once it is published]

Hi all,
As part of the Groovy 1.8 roadmap, we had an item for *supporting JSON* in
Groovy, similarily as to how we support XML, namely by providing a parser
(slurper) and a builder.
I've implemented a Groovy *JsonSlurper* and *JsonParser*, in the *
groovy.json* package.
It's currently in Trunk.
You can play with those parser and builder by using a snapshot of Groovy 1.8
that you can find on Bamboo, for example:
http://bamboo.ci.codehaus.org/browse/GROOVY-CORE-5493/artifact/deliverables
You can have a look at the *JSON GEP* that Andres and I started a few months
ago (GEP-7):
http://docs.codehaus.org/display/GroovyJSR/GEP+7+-+JSON+Support
It shows some of the examples.
But you can have a better overview of the various possibilities by looking
at the test cases here:
http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/test/groovy/json/
In particular the builder tests:
http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/test/groovy/json/JsonBuilderTest.groovy
And the parser tests:
http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/test/groovy/json/JsonSlurperTest.groovy
http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/test/groovy/json/RealJsonPayloadsTest.groovy
And you can have a look at the sources too:
http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/main/groovy/json/
<http://svn.codehaus.org/groovy/trunk/groovy/groovy-core/src/main/groovy/json/>Be
sure to look at the JavaDocs which show various examples as well.
Although JSON and XML are pretty different, it would be nice if xml builders
and json builder would be even closer (which is one of the goals of the
built-in JSON support), as for example the following cases are not covered
by the current implementation:
http://docs.codehaus.org/display/GroovyJSR/GEP+7+-+JSON+Support#GEP7-JSONSupport-Openquestions
I'd be interested in your input as how you'd expect such calls on the
builder should serialize the JSON output, or even if we should even support
them at all.
Thanks for your attention.
