Logtalk - Object oriented extension to Prolog
|
|
Release 2.15.2
|
|
|
|
Copyright (c) 1998-2003 Paulo Moura. All Rights Reserved.
|
|
=================================================================
|
|
|
|
This folder contains several examples of Logtalk programs. Most of
|
|
these examples need objects, protocols, and categories that are
|
|
defined in the Logtalk standard library or in other examples, so
|
|
you should load them first (see the NOTES file inside the library
|
|
folder and inside each example folder).
|
|
|
|
Some examples may redefine objects already loaded from other examples.
|
|
You may want to restart Logtalk after trying each example.
|
|
|
|
Some of the examples code have been adopted from public available
|
|
Prolog code and from known Prolog text books and are copyrighted by
|
|
the respective authors.
|
|
|
|
These are programming examples, meaning that you should study the
|
|
source files to fully understand them.
|
|
|
|
All examples are formatted using four spaces tabs.
|
|
|
|
By default, compiling an example generates a .xml documenting file for each
|
|
compiled entity (object, category, or protocol). See the xml sub-directory
|
|
for instructions on how to browse the .xml files for on-line reading or how
|
|
to convert the files to print-ready format.
