The latest kernel is S39. The S prefix indicates that the kernel is conformant to the standards laid down in The Book of Shen, 4th edition .

The downloads include versions built with extensions which are documented by the developer. Unless stated, all versions should support the features documented in The Book of Shen . We are happy to point to new downloads posted in the newsgroup but we do insist on standards of reliability in these ports. There is a folder of test programs in the sources for people to test their ports. Any Shen implementation should pass these tests modulo any memory limitations of the platform.

Kernel Downloads

The source code and installation instructions for the kernel can be downloaded from here.

Shen/tk

Shen/tk includes the latest library and Shen release. It is designed to work with TCL/tk under Windows.

Platform Operating System Comments
SBCL Windows Ported by Mark Tarver, S39, based on standard installation SBCL 2.0.0.
Both Shen (including the Shen Library) and Shen/tk (including the Shen
IDE) are included.
Scheme Various Ported by Bruno Deferrari.

There are a large number of pre-S series ports which can be found here. This site is maintained by Bruno Deferrari who maintains Github sources.

Useful Downloads.

The Shen Library

The most important is the Shen library written by Mark Tarver, developed from the closed source Shen Professional. This includes the standard library documented in the 'Learn' section of this site. In 2024 the library was upgraded to include the code for Shen/tk and concurrency.

Lib 2.0 Released 05/07/2024.

The Logic Lab

This is detailed in the Shen education channel and is available in Spring 2023 here.

Yggdrasil

Generates stand alone programs from Shen programs; described and downloaded from here.

THORN

Theorem prover based on HORN clause logic described here.

Editors

There have been several editors developed for Shen. Downloads exist for Emacs and Robert Koeniger developed a version for Sublime.

Regex Parsing

Eric Schulte developed a regex parser in the manner of Perl for parsing large files.

Foreign Function Interface

Mark Tarver developed a file-based FFI designed to work with the Shen instruction set

Miscellaneous

A compendium of other work, some historically early, is held here..
