Providing full WWW connectivity for LP and CLP systems
Welcome to the PiLLoW package home page. This package is
a public domain HTML/XML/HTTP conectivity package for Logic
Programming and Constraint Programming systems.
Copyright: This package is provided under the GNU Library General Public License
Downloading: The package has been developed in the context of the
Ciao Prolog system and it comes as
part of this system's libraries, i.e., to use PiLLoW within Ciao you
only need to load the appropriate library. However, PiLLoW is also
available for a number of other popular LP/CLP systems, see the links below for downloading.
Support: The PiLLoW/Ciao developers can be reached at ciao@clip.dia.fi.upm.es.
Bugs should be reported to ciao-bug@clip.dia.fi.upm.es.
Specific professional support and maintenance services are
available. Please contact clip@dia.fi.upm.es for
details.
Subscribing to the PiLLoW/Ciao mailing list: If you
download PiLLoW, we highly recommended that you subscribe to the ciao-users@clip.dia.fi.upm.es
mailing list, so that you receive updates, bug fixes, and any other
related info. You can subscribe by checking the approriate
option during the download process, or by sending an ascii message to ciao-users-request@clip.dia.fi.upm.es,
containing in the body the word subscribe alone in one
line. Discussion is limited to PiLLoW or Ciao-Prolog related topics and we will
keep your email address strictly confidential. An archive of all
messages to the list is available.
Documentation: Apart from the reference manual included
with the distribution (as part of the Ciao reference manual in the case
of the Ciao system) and available on-line
below we have prepared an on-line tutorial describing Internet/WWW
programming in general and with PiLLoW in particular as
slides with examples (in pdf-recommended- or
html) or
as a (somewhat older) paper in on-line version or ps file. These documents explain the
functionality of most of the library. You have also access here to the
README and INSTALL files included with the distribution.
Examples: Here are some (very simple) examples of what can
be done with the package (the actual possibilities are of course
endless). They are prepared to run in the Ciao system, in
other systems they need minor changes, notably in the header.
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. Note, however, that this manual is written for the Ciao system, so if you use it in other systems, minor details in the documentation may not completely agree. For example, whereas in Ciao the library is a package which loads modules html and http, in the other systems it is just one module pillow. Thus, do not consider the Library usage information in other systems. PiLLoW is distributed under the GNU Library General Public License.

These are a few sample applications which have been interfaced to the
WWW using PiLLoW:
A simple HTML page and
the code to produce it
A simple form generator + handler and
the code to produce it
A richer form generator +
handler and
the code to produce it

pillow: The PiLLoW Web Programming Library
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 such 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. List of all available PiLLoW distributions (tared, gzipped)
