Hi.
Can't you add a parser function too ?
A parser function needs to return an object:
* either the JSON object from some JSON library, but that means
binding the Velocity tool to a specific JSON library and I tried to
avoid this for the moment until we reach an agreement regarding the
JSON library to use
* a wrapper for the JSON object from some JSON library to hide the
JSON implementation, but that's a lot of work and I don't have time
for it right now
* a Java object, but for this you need a JSON-Java mapping, which is
specific to the JSON library used and it requires some work to make a
generic binding method
Right now, we have to use groovy for JSON parsing. It would be better to
have it in velocity directly, don't you think ?
Yes, but I don't have time for it right now.
Thanks,
Marius

http://lists.xwiki.org/mailman/listinfo/devs Hi devs,
Following the discussion on
http://lists.xwiki.org/pipermail/devs/2012-March/049889.html I'd like
to add a JSON Velocity tool that has (for now) just one method:
/**
* Serialize a Java object to the JSON format.
* <p>
* Examples:
* <ul>
* <li>numbers and boolean values: 23, 13.5, true, false</li>
* <li>strings: "one\"two'three" (quotes included)</li>
* <li>arrays and collections: [1, 2, 3]</li>
* <li>maps: {"number": 23, "boolean": false,
"string": "value"}</li>
* <li>beans: {"enabled": true, "name": "XWiki"} for
a bean that has
#isEnabled() and #getName() getters</li>
* </ul>
*
* @param object the object to be serialized to the JSON format
* @return the JSON-verified string representation of the given object
*/
public String serialize(Object object)
This method is able to do what both of the initially proposed methods
were able and it doesn't expose the JSON library used (so that we can
change it later if we want). I'll use json-lib for the initial
implementation and we can move to Jackson or other JSON library later.
WDYT? I'd like to commit this ASAP.
Thanks,
Marius
