DebugProgram class supports Qore Program debugging via ProgramControl.
One instance may be assigned to one or more ProgramControl instances which may run in one or more threads. ProgramControl is added to the debugging list, next the program being debugged notifies the debugger when the next execution event occurs. Calling of notification method is always performed in the program thread. When the program flow is to be interrupted then it happens in the notification method of this class. Then debugger decides to continue and then returns from the notification function and passes Debug Run State Constants value "step option" code back.
The debugger should probably handle control in separate thread.
The DebugProgram class defines the interface and the real functionality should be implemented in a child class.
- Restrictions:
- MUST HAVE: Qore::PO_ALLOW_DEBUGGER
- Example:
const code = "for (int i=0; i<10; i++) {}";
class MyDebugProgram dbg() inherits DebugProgram {
private:
onAttach(ProgramControl pgm, reference rs) {
rs = DebugStep;
}
}
ProgramControl p = ProgramControl::getProgram();
dbg.addProgram(p);
pgm.parse(code);
pgm.saveProgram();
pgm.run();
