Dear All,

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

- Signal Handling:
The Dogelog player now provides a post() routine
in the target language, which allows a rudimentary
posting of an exception to the Prolog interpreter.
This is already used in browser examples
for a button to abort Prolog execution.

- library(compat):
We added some bitwise operation which are outside
the ISO core standard, such as the evaluable
functions msb/1, lsb/1, etc.. Unfortunately not
all target languages have good support, so that
the implementations are a little bit a cludge.

- library(format):
Thats a new library with native support by
atom_number/4 for the various target languages.
The format/[2,3] itself is a pure Prolog implementation
still very minimal, without tab-stops, which
we will possibly anyway not need when later
generating HTML DOM.

Have Fun!

Dogelog player is a Prolog system written 100%
in Prolog targetting the JavaScript and the Python
platform. We have adopted the core benchmark suite
from formerly Jekejeke Prolog and usually run it for
both nodeJS and PyPy.

The benchmark suite gives some proof that the new
PyPy v7.3.10 offers a significant speed-up of ca. 25%
over its previous versions. We report month-to-month
benchmark results and some thoughts on the future
of the Dogelog player.

The new PyPy v7.3.10 is a motivation to keep the Python
target platform for the Dogelog player. It seems that
PyPy has once narrowed the gap to nodeJS. On the
other hand the Dogelog player gets reminded to
investigate new ideas such as an auto tuning garbage

collector and hopefully a speed-up changelog as well.

The Dogelog Player is a Prolog system that is 100%
implemented in Prolog itself. Although browsers provide
a document.write() JavaScript call, we created a
library(markup) that allows a more concurrent and
chirurgical output into an existing document.

The new library(markup) provides two enhancements,
escaped current output and new predicates. The new
predicate tag/2 that combines tag/1 with format_atom/3
offers quite some synergy. The new table generator and the
new chart generator provide encouraging examples.
