The "problem" I am facing is that if I use the SWI-Prolog module system, defining modules and using them in other modules, if an imported module changes SWI-Prolog does not take it in consideration when loading the importing module. For example:
% file topmod.pl
:- module(topmod, [thetop/0]).
:- use_module(bottommod).
thetop :-
thebottom(S),
format('This is the top~nAnd this is ~w~n', [S]).
% file bottommod.pl
:- module(bottommod, [thebottom/1]).
thebottom('the bottom').
If I now load them:
?- [thetop].
% bottommod compiled into bottommod 0.00 sec, 2 clauses
% topmod compiled into topmod 0.00 sec, 6 clauses
true.
?- thetop.
This is the top
And this is the bottom
true.
If I now change the file:
% file bottommod.pl changes
- thebottom('the bottom').
+ thebottom('the foobar').
?- [thetop].
% topmod compiled into topmod 0.00 sec, 1 clauses
true.
?- thetop.
This is the top
And this is the bottom
true.
?- module(bottommod).
true.
?- listing.
thebottom('the bottom').
true.
How should I force Prolog to consult all the imported modules and the modules they import, short of using consult?
