The Prolog cross-referencer located in qplib(tools)
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. See the file library('xref.doc')
for more information.
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.
