[Lift] Re: Typesafe JSON builder?
I've read some stuff about Jorge Ortiz's Json Parser and how its super type safe, i guess you could use that same logic to create your builder (and I would not be surprised if theres something like that laying around in Lift). I hope if there is, someone will point you in the right direction, all I can do is point you to that parser: http://technically.us/git?p=dispatch.git;a=blob;f=src/main/scala/dispatch/Json.scala;h=776da7b6c399d2985dfbed74bd31a197568360f9;hb=HEAD On Jul 9, 10:35 am, Jeppe Nejsum Madsen je...@ingolfs.dk wrote: Hi, Has anyone made a typesafe JSON builder?

Please take a look on JsObj. But what is your exact use case? ... generate JSON constructs from Scala and send then to browser?

That's what I'm using now and it's a pain:
def generateOptions = JsObj(
(title, My title),
(series, JsArray(JsObj((Label,MyLabel,
(seriesColors, JsArray(#00,#cc)),
(axes, JsObj(
(xaxis, JsObj(
(renderer, JsVar($.jqplot.CategoryAxisRenderer)),
(ticks, JsArray(data.flatMap(series = {series.labels.map(v
= v.toString)}) : _*))
)),
(yaxis, JsObj(
(min, 0),
(tickOptions, JsObj(
(formatString, %d)
))
))
)),
(seriesDefaults, JsObj(
(renderer, JsVar($.jqplot.BarRenderer)),
(rendererOptions, JsObj(
(barDirection, horizontal),
(barPadding, 8),
(barMargin,20),
(barWidth, 20)
))
)))
But what is your exact use case? ... generate JSON constructs from
Scala and send then to browser?
Yes, I want the above JSON object (which is just a subset of the full
capabilities) to be generated in Scala, so I:
- will get typechecking
- Don't have to remember field names
- Can't get autocompletion on valid values for things like
- e.g. barDirection
/Jeppe

[Lift] Re: Typesafe JSON builder?
Perhaps consider this other scala JSON lib:
http://github.com/jonifreeman/literaljson/tree/master
NB: I've not used this, im just adding it for discussion as it might
help you.
Cheers, Tim

In all seriousness, one of the pieces of Goat Rodeo
(http://goatrodeo.organd Goat Rodeo will become part of Lift once GR
is stable) is objects that
will know how to serialize themselves as JSON. So, you'll get type safety
and bi-direction serialization. In the mean time, I think Marius has some
stuff in Record that also does bi-directional JSON.
