Re: Debug Interface for the mozjs, how to start/stop/pause/continue the js engine

Thanks for your answer !

Ok for the jsdebugger.jsm being a browser only tool.

But how to make available the Debugger in the mozjs ? =

Currently any use of Debbuger[1], trigger an exception like this one : Exce=
ption at line 1 column 11 from file ><, errorMessage=3DReferenceError: Debu=
gger is not defined



[1] through a call JS::Evaluate with :
-------------------------
var dbg =3D new Debugger(root);
dbg.onEnterFrame =3D function (frame) {
    frame.onStep =3D function () {
        onStepCallback();
    };
}
-------------------------
