How to increase the char column width for the scalacheck console output?

When running scalacheck from an sbt console the output is limited by 76 char column width:

$ sbt test:console

import scalaz._
import Scalaz._
import scalacheck.ScalazProperties._
import scalacheck.ScalazArbitrary._
import scalacheck.ScalaCheckBinding._

scala> monad.laws[List].check

Is there any way to increase that limit?

It is impossible as the width value is hard coded in ConsoleReporter. However, if you are running your tests with the main defined in Properties, you can do the following:

object MyCheck extends Properties("My property check") {

  override def overrideParameters(p: Test.Parameters) =
      p.withTestCallback(WideConsoleReporter)

  ...

}

And then in your own code, create WideConsoleReporter based on ConsoleReporter.

This is unfortunately not possible to change, as it is hard-coded in ScalaCheck (in https://github.com/rickynils/scalacheck/blob/master/src/main/scala/org/scalacheck/util/ConsoleReporter.scala). I suggest opening an issue at ScalaCheck's Github page.
