  • ANN: Dogelog Player 1.0.3 (Signal Handling)

    From Mostowski Collapse@21:1/5 to All on Wed Jan 18 00:51:35 2023
    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.

    We already reported about our new library(markup)
    that allows non-blocking generation of tables and charts.
    We will report here how two small additions allow the
    smooth generation of animations.

    To perform some animation our plan is to clear a SVG port,
    then populate it, then sleep some time and then repeat the
    process. Unfortunately auto-yielding might show an incomplete
    scene causing flickering despite the double buffering. There is
    a new predicate shield/1 to the rescue.

    The Dogelog Player is a Prolog system for the JavaScript
    and the Python platform. On both platforms the Prolog
    system is basically single-threaded but is executed as an
    asynchronous procedure that automatically yields. We
    recently added Ctrl-C and exception chaining.

    We discovered the Logtalk idiom which provides a solution
    in ISO core standard only to the cleanup problem of a
    deterministic goal. We gave the idiom the new predicate name setup_once_cleanup/3 and equipped it with exception
    chaining, written in Prolog itself.
