The JSON parser in the Scala library was a short project by Derek Chen-Becker.  It's no longer really supported.  The best JSON implementation on Scala is the lift-json libraries.

do everyone here agree with this? Does scala.util.parsing.json.JSON worth trying?

Thanks

I've been using the Dispatch [1] json libs, which I like. To be honest, its not documented very well, though. Takes some getting used to, but once you get it its pretty cool.

scala....JSON is sooo slooow.

better choice is a liftweb one or you can grab one here:

https://github.com/vladimirk/butter4s/blob/master/json/src/butter4s/json/Parser.scala

It's based on liftweb-json, but produces result of lists-and-maps
instead of case classes, handles parsing of primitives (while liftweb
handles only objects and arrays) and a bit faster.

Actually I personally like scala's Parsers Combinators, and it is sad to see this comment and to see the JSON library becoming obsolete.

OK, let me just correct this. The JSON library is not unsupported. I have a patch
waiting to go into the next Scala release and I'm happy to fix bugs that people
report in Scala's Trac. Now, as for performance, lift-json is going to be a whole
lot faster because it's written to be fast. Scala's JSON is written using the
parser combinator library which has some limitations in terms of performance.

In other words, it's not going anywhere and it's quite useful as a bundled parser,
but if you're going to be working with lots of JSON it would behoove you to look
at some of the other options that people have mentioned.

Cheers,

Derek

This seems to be true for the whole dispatch thing, and for unfiltered as well.
Really sad, as I think many people could really profit from being tutored into that
matter. But having to explore how these things work in sometimes .. ahem ... unconventional
ways, does not help to target the mass.

If they at least were on github (or other public dvcs), people could at least contribute documentation back more easily.
