40c3e31955 ENHANCED: phrase_from_file/[2,3] now read the file lazily. 
This allows processing extremely large files. In addition, the
efficient string representation helps to reduce memory usage.

These features unleash the full power of Prolog for text processing,
the exact use case Prolog was designed for.

How about an actual raven for a logo?
 2020-05-27 00:19:41 -03:00
Markus Triska
7cc92ec1c1 ADDED: Logo. 
Motivation and considerations:

- A Scryer certainly needs a raven. Ravens are among the most
  intelligent animals on earth.
- When writing Prolog programs, a few strokes are often enough.
- Purple is the colour most associated with magic and royalty,
  indicating the almost surreal and pure features provided by Scryer,
  in the lineage of Marseille Prolog.
- The shape of the silhouette looks a bit like an "S" for "Scryer".
- A square which surrounds the image is traditionally associated with
  finishing a proof (square, Latin "quadratum", has the same starting
  letters as "quod erat demonstrandum").

I call this raven: *Cryer*. Cryer is an archaic spelling for "crier",
an officer who makes public announcements in a court of justice.
The Prolog top-level likewise makes announcements about what is true.
