Get_dict_ex/3 does not exist?

get_dict_ex/3 seems to not be accessible:

:- begin_tests(get_dict_ex).

   nonempty_dict(foo{x:alpha, y:bravo, z:charlie}).

   test("bagof/3 collects with get_dict_ex/3", [true(T)]) :-
      bagof(Key-Value,  get_dict_ex(Key,Dict,Value), Bag),
      T = (SortedBag == [x-alpha, y-bravo, z-charlie]).
:- end_tests(get_dict_ex).

rt(get_dict_ex) :- run_tests(get_dict_ex).


?- rt(_).
% PL-Unit: get_dict_ex 
ERROR: user://1:12:
        test bagof/3 collects with get_dict_ex/3: received error: findall_loop/4: Unknown procedure: plunit_get_dict_ex:get_dict_ex/3
% 1 test failed
% 0 tests passed

Maybe it has been removed or renamed? Once could just use .get/2 (“dot-get/2”) after all.

I see. That has existed in the exploratory phase introducing dicts. Eventually became ‘$get_dict_ex’/3 as I considered it to be too obscure for the public API. Will delete from the docs.

P.s. If you write tests, please consider making pull requests on the test suite.

Okay. Currently I’m attaching them to the manual as explainers.

I am pretty sure David knows this already, for others who don’t there is a wiki that shows how to do this GitHub Pull Request.

If anyone finds a problem or bug with it, as it is a wiki please fix or let me know. I will warn you my Git skills are horrible; no matter how many times I get good at it for a few weeks after the next long pause I seem to forget it all again.

Thanks. Be aware that the current page annotation system is pretty broken en contains a lot of outdated or otherwise dubious messages. This will probably be integrated with Discourse in due time. Not sure what should happen to the old annotations. I guess we can migrate them, but they probably need reviewing and cleanup first.
