Hi,

I compiled and ran the demo. The test seems to work okay, but fails for example.kw. Any thoughts?
Thanks much in adv,

Hoon,

P.S: The old example init does not work anymore?
void initexample()
{
// experimental initialization stuff
init_rtype();
example = new ExtensionModule("example");
example->add("sum", ex_sum, "sum(arglist) = sum of arguments");
example->add("test", ex_test, "test(arglist) runs a test suite");
example->add("r", r_new, "r(start,stop,stride)");
Dict d = example->initialize();
Object b(FromAPI(new r(1,10,2)));
d["a_constant"] = b.getAttr("c");
}

    The kw() example function fails unless you pass at least
    one keyword argument:
    E.kw(1, two=2)
    works. But the source code for ex_keyword looks like it
    should work even without keword args.

    Fixed in the current code. THe code needed to take account of
    the keywords dict being a NULL poiinter.

    NOte that E.kw( dict ) passes one param, a dict.
    Maybe you wanted E.kw( a=1, b=2 ) ?
