Predicate searching by wildcard or similar

[Sean Charles]

Hi,

I just wrote a *really simple* testing framework for my project, it looks like this at the test script end:

test_package([it('should ensure that global values have expected settings', defaults_correctly_set_test)

    ,it('should correctly set the quiet flag on "-q"', respect_quiet('-q'))

    ,it('should correctly set the quiet flag on "--quiet"', respect_quiet('--quiet'))

    ,it('should correctly set the wrap flag on "--wrap"', respect_wrap)

    ,it('should correctly set the check flag on "--nocheck"', respect_check)

    ,it('should add unhandled options as source filenames', filename_check)

    ,it('should throw exceptions on unknown options', handle_unknown_options)

    ]).

The test_package predicate is called from the framework by the script, the script pulls in the file and that has an initialisation instruction:

:- initialization(run_tests).

run_tests :-

test_package(AllTests),

maplist(call, AllTests),

ink(normal, '*done*'),

stop.

What would have made it *really* nice was to have been able to find all predicates starting with test_ or ending with _test etc. so that I would not have needed to make the test_package predicate unify the variable with the list of tests to be run. Some tests mentioned above...

defaults_correctly_set_test :-

cl_set_defaults,

get_all_globals([],[],user_input,user_output,php,nowrap,check,plain,noisy).

respect_quiet(Flag) :-

cl_set_defaults,

process_option(Flag),

get_all_globals(_,_,_,_,_,_,_,_,quiet).

As you can see, having to enter the test predicate AND enter it in the test package isn’t ideal ALTHOUGH it does allow me to provide a nice label but I could have done that with a really long predicate name anyway.

So, how would I do that in GNU Prolog…if it is possible. The listing() predicate is not much help in this instance…

Thanks,

Sean.
