10.33 The PiLLoW Web Programming Library—library(pillow)

This third-party library is unsupported, and included ‘as-is’.

The PiLLoW library (“Programming in Logic Languages on the Web”) is a free Internet/WWW programming library for Logic Programming Systems that simplifies the process of writing applications for such environment. The library provides facilities for generating HTML or XML structured documents by handling them as Prolog 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.

PiLLoW is documented in its own reference manual, located in https://cliplab.org/Software/pillow/pillow.html. The following points are worth noting wrt. the PiLLoW reference manual:

• PiLLoW is automatically installed with the SICStus Prolog distribution. No extra action needs to be taken.
• PilloW comes as a single library module, library(pillow).

  This subsumes the various load_package/1 and use_module/1 queries mentioned in the PiLLoW reference manual.
