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.
