You can also debug Parrot code by using the debug_init, debug_load and debug_break ops in ops/debug.ops.

int main(int argc, char *argv[])

Reads the PASM or PBC file from argv[1], loads it, and then calls Parrot_debug().

static void PDB_add_exception_handler(Parrot_Interp)

Adds a default exception handler to PDB.

*/

static void PDB_run_code(Parrot_Interp interp, int argc, char *argv[]) { new_runloop_jump_point(interp); if (setjmp(interp->current_runloop->resume)) { free_runloop_jump_point(interp); fprintf(stderr, "Caught exception\n"); return; }

    /* Loop to avoid exiting at program end */
    do {
        Parrot_runcode(interp, argc, argv);
        interp->pdb->state |= PDB_STOPPED;
    } while (! (interp->pdb->state & PDB_EXIT));
    free_runloop_jump_point(interp);
}
