c0df8cb578 update answer to use the latest toplevel improvements 2020-04-19 19:18:47 +02:00
Markus Triska
450591d5a9 ENHANCED: the toplevel interaction now supports RETURN as a synonym for "." 
This is made possible due to the recent improvements by @notoria.

786f0b5ca2 incorporate the latest improvements in the description of partial strings 
As of 6e4b76a3b4, the use of
partial_string/3 can be replaced by (=)/2 in this example.

fac6d54986 extend description of strings and partial strings 
Also, explain in more detail what this feature means to Prolog
application programmers, and the strategic direction of Scryer.

8b1df2e9ca ADDED: CLP(ℤ), Constraint Logic Programming over Integers 
library(clpz) implements declarative integer arithmetic.

The most important predicates for reasoning about integers are:

    (#=)/2    equality
    (#\=)/2   disequality
    (#<)/2    less than
    (#>)/2    greater than
    (#=<)/2   less than or equal to
    (#>=)/2   greater than or equal to

In addition, the library provides several global constraints, such as
all_distinct/1 and global_cardinality/2, and reification predicates
that reflect the truth values of constraints into integer variables.

Enumeration predicates such label/1 and labeling/2 can be used to
search for solutions over finite domains.

Almost all Prolog programs also reason about integers. Therefore, I
recommend to add this library to your .scryerrc configuration file so
that declarative integer arithmetic is available in all your programs.

Enjoy!
