Logtalk 2.17.2 now available for downloading

[Paulo Moura]

Hi!

Logtalk 2.17.2 is now available for downloading from the Logtalk web 
site:

        http://www.logtalk.org/

Logtalk is an open source object-oriented extension to the Prolog 
programming language. Integrating logic programming with 
object-oriented and event-driven programming, it is compatible with 
most Prolog compilers. It supports both prototypes and classes. In 
addition, it supports component-based programming through 
category-based composition.

This version improves documentation for first time users, includes a 
new programming example, corrects some bugs related to operator 
handling and local dynamic predicates, updates the compiler to allow 
source files containing only directives, and replaces the examples 
Prolog loader utility files by Logtalk files, thus simplifying example 
loading for new users.


From the release notes:

* Updated the Logtalk compiler to allow compilation of source files 
which contain only directives and no entity definition.

* Simplified loading of library and example entities by using Logtalk 
source files as loader files.

* Some improvements to the documentation, including the QUICK_START 
file and the User Manual for first-time users, and to the example 
descriptions.

* Corrected a bug in handling of local object operators that are also 
global operators.

* Corrected a bug where dynamic directives are not being generated for 
dynamic predicates that lack a scope directive or an initial set of 
clauses.

* Corrected a bug where local dynamic predicates would need a private 
scope directive in order to allow clauses of the predicate to be 
retracted.

* Simplified compilation of dynamic and discontiguous predicate 
directives.

* Added new "logic" example implementing a translator from logic 
propositions to conjunctive normal form.

* Corrected a problem with wrong end-on-lines on some files.

* Added a shell script for easy integration of Logtalk with CIAO Prolog.


The CVS tag for this release is "lgt2172".


Happy logtalking!

Paulo
