PiLLoW version 1.1, included with the latest version of Ciao Prolog (1.6#1), is now available for SICStus 3.8, SWI Prolog 3.3, and YAP 4.3.0. Improvements from the previous version include handling of XML code, templates (HTML/XML code with 'named holes' which are associated to logical variables), and a reference manual. Please see:

for details.

The PiLLoW library (``Programming in Logic Languages on the Web'') is a public domain Internet/WWW programming library for Logic Programming Systems which simplifies the process of writing applications for this environment. The library provides facilities for generating HTML or XML structured documents by handling them as Herbrand terms, producing HTML forms, writing form handlers, processing HTML templates, accessing and parsing WWW documents (either HTML or XML), accessing code posted at HTTP addresses, etc. The PiLLoW library has been developed in the context of the &-Prolog and Ciao systems, but it has been adapted to a number of popular Logic Programming systems. PiLLoW is distributed under the GNU Library General Public License.

P.S. If you have ported PiLLoW to other Prologs, please let us know!
