when u say line=reader.readLine() its a assignment which return Unit in scala, and its always not null .

so just have to compare against variable line

something like this shud work

while({line=reader.readline();line!=null) {
doSomething()
}

Not even if you wrote it in C. And recursive as well? This should be a one-liner nowadays. Maybe two.

Hi Mark, try this:

import scala.io.Source
import java.io.InputStream

def convertStreamToString(is: InputStream) : String =
Source.fromInputStream(is).getLines.reduceLeft(_ + _)

Source has a load of useful methods like fromFile or fromURL.

I was just playing around with code in the REPL so I was seeing what I could do just with the libraries available there. Haven't worked out how to import 3rd party libraries into that environment yet. I guess that would be a good next thing to work out! Thanks for the link though, will check that out.
