Declarative loops and list comprehensions
|
| |
Hi, After adding into B-Prolog 7.4 the foreach built-ins for describing loops and the list comprehension notation for constructing lists, I felt that these constructs could benefit Prolog in general. Therefore, I have made the updated interpreter available at: [link] It can easily be ported to other Prolog systems. B-Prolog compiles... more »

dif/2, an illustration
|
| |
The predicate dif/2 was proposed in A. Colmerauer's Prolog II language in 1981. His later work in constraint logic programming is well- known, and prompted by Markus Triska's enthusiasm for using this as introductory element of Prolog, I formulate the follow example both to illustrate the benefits of dif/2 and to elevate discussion of whether... more »

|
| |
In chapter 1.2 Bratko presents relation sister which uses predicate different. He "assumes" that it is known to the prolog system. However, both SWI prolog and Gnu prolog do not know about it.

| |

I can create a dialog in SWI-Prolog/XPCE with buttons and a picture, and use the buttons to request drawing in the picture and to quit the dialog, etc. The one thing I can't figure out is how to resize the picture. Sending it recogniser, new (resize_gesture) does not add any new behavior. Sending it an explicit... more »
