The use_module/1
predicate from section 6.3
defines import and export relations based on the filename from which a
module is loaded. If modules are created differently, such as by
asserting predicates into a new module as described in section
6.13, this interface cannot be used. The interface below provides
for import/export from modules that are not created using a module file.
- export(+PredicateIndicator,
...)
-
Add predicates to the public list of the context module. This implies
the predicate will be imported into another module if this module is
imported with use_module/[1,2].
Note that predicates are normally exported using the directive module/2. export/1
is meant to handle export from dynamically created modules.
- import(+PredicateIndicator,
...)
-
Import predicates PredicateIndicator into the current context
module. PredicateIndicator must specify the source module
using the <module>:<pi> construct.
Note that predicates are normally imported using one of the directives use_module/[1,2].
The import/1
alternative is meant for handling imports into dynamically created
modules. See also export/1
and export_list/2.
