ANN: Dogelog Player 1.2.4 (Non-Backtracking Hashtable)


Admin User, created Nov 02. 2024

Dear All,

We are happy to announce a new edition of the Dogelog player:

- New library(misc/dict):
  We have moved some predicates from the library(misc/json) into our own library(misc/dict).  We made sure that the data structure of the Prolog dicts now follows the input order semantics.

- New library(util/hash):
  To enable the implementation of hash tables, Novacore now has a term_hash/2 predicate.  The implementation differs from the Prolog dict in that change_arg/3 is used for destructive updates.  We have also dispensed with the input order.

- Improved library(sequence):
  Hash tables can easily be used to model sets of keys, for example by using the value "true" as an indicator.  This allowed us to re-implement the distinct/1 predicate.  The use of numbervars/3 ensures that key variants are identified.

For more details: Dogelog

Have Fun!
