List the properties for predicate(s)

predicate_properties(M:Name/Arity,(predicate(M:Name/Arity),properties(Bag))) :-
    ground(M),
    ground(Name),
    ground(Arity),
    var(Bag), !,
    compound_name_arity(Head,Name,Arity),
    bagof(Property, predicate_property(M:Head,Property), Bag).

predicate_properties(M:Name/Arity,Sets) :-
    var(Sets), !,
    setof(pi(M:Name/Arity),local_predicate_generator(Name,M:Name/Arity),PI_set),
    predicate_properties(PI_set,Sets).

predicate_properties(PI_set,Sets) :-
    member(pi(M:Name/Arity),PI_set),
    bagof(Set,predicate_properties(M:Name/Arity,Set),Sets).

local_predicate_generator(Name,M:Name/Arity) :-
    current_predicate(M:Name/Arity),
    local_predicate(M:Name/Arity).

local_predicate(M:Name/Arity) :-
    compound_name_arity(Head,Name,Arity),
    \+ predicate_property(M:Head,imported_from(_)).

I made this a Discourse Wiki topic so that anyone with a proper trust level can edit this. If you want to improve the code, add some documentation, or other, feel free.

There will probably be a few more topics in this category related to Prolog code analysis that I might pull together into a Wiki, but for now having the code in a more prominent place is better than being buried in a Wiki discussion topic.

SWI-Prolog includes some graphical tools related to code analysis,.

Prolog Navigator

?- prolog_ide(open_navigator(.)).
true.

Cross-referencer

?- gxref.
true.

Also see: Prolog code walker

Note: prolog_walk_code/1 is used by Pack callgraph.
For an example of using using callgraph see this post.
