• New version of Wraith Scheme (parallel processing R5 Scheme for Macinto

    From Jay Freeman@21:1/5 to All on Sat Mar 4 00:27:48 2023
    Today I released version 2.28 of Wraith Scheme.

    Wraith Scheme 2.28 is a shareware and open-source full R5 Scheme
    implementation for the Apple Macintosh, with enhancements for
    parallel processing, by which I mean multiple copies of the
    Wraith Scheme application (separate Unix processes) all running
    at once, sharing Scheme main memory.

    Wraith Scheme 2.28 is a full 64-bit Macintosh application, that
    runs on Macintoshes using either Intel processors or Apple's
    proprietary ARM-based processors ("Apple silicon"), and that
    are running at least MacOS 11.6 ("Big Sur").

    This release also contains a release of a derivative R5 Scheme
    program, Weasel Scheme, which runs on a Raspberry Pi 400.

    There is no new release of Pixie Scheme III or Pixie Scheme II
    at this time.

    Wraith Scheme 2.28 adds other enhancements, notably procedures
    for fast operations on matrices whose values are 64-bit IEEE
    floating-point numbers.

    These pages also include links to a whole lot of documentation
    for these programs.

    Source for Wraith Scheme 2.28, for Pixie Scheme II 1.02, and for
    Pixie Scheme III 1.12 is available under the GNU General Public
    License; for details, and to download the source distributions,
    see the software page of my web site.

    The makefile for Wraith Scheme 2.28 contains targets to build
    Weasel Scheme.
