Trace to Opera Dragonfly

Question

I am using Opera on a Windows PC and developing for a device. I can telnet into the device and manually run the browser which gives me the browser output.

Is it possible to trace messages into both Dragonfly and the Opera console? I can see a window.alert() message show up in the console, but I would also like to trace messages for simpler debugging and status tracking both within Dragonfly on PC and Opera on the device.

Answer 1

function debug(text) {
  ((window.console && console.log) ||
   (window.opera && opera.postError) ||
   window.alert).call(this, text);
}

I'm not positive this will solve your problems (I don't have much experience with Dragonfly) but it seems that opera.postError is the general API call for console logging on Opera.

Answer 2

console.log will work in Opera and Dragonfly from Opera 11. We added support for both the Console and the Command Line APIs from Firebug. See http://my.opera.com/dragonfly/blog/getting-opera-dragonfly-ready-for-opera-11/ for more information.
