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.

Have Fun!

A further library(util/tree) was realized, that
uses the rules of Okasaki's Red-Black tree with
destructive updates. change_arg/3 has become
our favorite gadget to realize imperative
datastructures in Prolog.

No setup_call_cleanup/3 brakets are needed, since
we can rely on its Prolog garbage collector
integration. We compared hash table versus red
black tree. For the million row challenge we see
an overhead below 10%.

Dogelog Player is a Prolog system written in 100%
Prolog. We discovered that XSB Prolog provides an
interesting predicate unnumbervars/3 which we
recently ported to Dogelog Player. Together with
numbervars/3 it can be used to compile and
execute λ-Prolog.

We moved from Prolog to λ-Prolog without overdoing
it. Our only concession to lambda calculus was
alpha conversion to avoid variable clashes. We
could not only demonstrate “what-if” queries, but
also parametrization of unchanged
predicate arguments.

Dogelog Player is a Prolog system written
in 100% Prolog. We discovered that XSB Prolog
provides an interesting predicate unnumbervars/3
and did a rework of library(aggregate). We show
how the library can be used for anomaly
detection in time series.

Together with the non-ISO core extension call_nth/2
from library(sequence) one can quickly define
sliding windows computations in Prolog itself.
We compute moving variance and moving delta for
actual bitcoin market prices. Using both indicators
we can identify an abnormally in november.

Dogelog Player is a Prolog system that is 100%
written in Prolog itself. Previously only tested
with node.js, we produced a release that is able
to run on the newly available Bun command line
JavaScript engine. bun.js itself is realized with
the novel programming language Zig.

To use bun.js we fixed a programming error in that
we replaced our operating system success test by
falsy tests (!err). We found 4 non-critical discrepancies
among novacore and libraries. Possibly due to an older
JavaScript version, bun.js was slightly slower
than node.js.
