json - Working with concatenated JValues in liftjson -


using scala 2.8 , lift 2.2.

i'm calling github api , requesting repositories user. when user has less 30 repos 1 call made , there no need concatenate jvalues. however, when user has more 30 repos multiple calls made. concatenate these results these calls , "flatten" them. i.e. "repositories" name on jvalue should return repos not first 30.

the code below returns following: array(list(jobject(list(jfield(repositories,jarray(...jobject(list(jfield(repositories,jarray...))))))))

what want is: array(list(jobject(list(jfield(repositories,jarray(....))))) repositories name points all of repos.

i've wrestled bit , can't seem it.

import java.io._ import net.liftweb.json.jsonast._ import net.liftweb.json.jsonparser._ import org.apache.http.client.methods.httpget import org.apache.http.impl.client.{ defaulthttpclient }  object github extends application {   implicit val formats = net.liftweb.json.defaultformats    val client = new defaulthttpclient()    var repos = jarray(list[jvalue]())    //pick on mojombo since has 30+ repos requires calls api   var method = new httpget("http://github.com/api/v2/json/repos/show/" + "mojombo" +   "?page=1")    var response = client.execute(method)    var instream = response.getentity.getcontent();   var reader = new bufferedreader(new inputstreamreader(instream))   var line1 = reader.readline    method = new httpget("http://github.com/api/v2/json/repos/show/" + "mojombo" + "?page=2")    response = client.execute(method)    instream = response.getentity.getcontent();   reader = new bufferedreader(new inputstreamreader(instream))   val line2 = reader.readline    println(parse(line1) ++ parse(line2)) }

function 'merge' should merge jsons described:

parse(line1) merge parse(line2)

or more generically:

list(json1, json2, ...).foldleft(jnothing: jvalue)(_ merge _)
