% start by compiling and loading the Prolog module files as objects:

| ?- logtalk_load(modules(loader)). ...

% call one of the module exported predicates using message-sending:

| ?- test::names.

paulo carlos helena yes

% same goal as above but the call is made using a meta-predicate % imported from other module:

| ?- test::test.

paulo carlos helena yes

% test the compilation of the module export/1 directive; module % exported predicates become public predicates:

| ?- exports::current_predicate(Pred).

Pred = p/1 yes

| ?- exports::predicate_property(p(_), Prop).

Prop = public ; Prop = static ; Prop = declared_in(exports) ; Prop = defined_in(exports) yes

% call the module exported/public predicate using message-sending:

| ?- exports::p(N).

N = 1 ; N = 2 ; N = 3 yes

% test the compilation and use of meta-predicates:

| ?- test::names(Names).

Names == [paulo, carlos, helena] yes

| ?- test::test(Names).

Names == [paulo, carlos, helena] yes
