4.11.4 Converting Non-module Files into Module Files

The Prolog cross-referencer can automatically generate module/2 declarations from its cross-reference information. This is useful if you want to take a set of files making up a program and make each of those files into a module file. For more information, see The Cross-Referencer

Alternatively, if you have a complete Prolog program consisting of a set of source files {file1, file2, …}, and you wish to encapsulate it in a single module mod, then this can be done by creating a “driver” file of the following form:


:- module(mod, [ … ]).

:- ensure_loaded(file1).
:- ensure_loaded(file2).

When a module is created in this way, none of the files in the program {file1, file2, …} have to be changed.
