More Schemes from John

[lassik]

Here's a list of the Schemes given in https://bitbucket.org/cowan/r7rs-wg1-infra/src/default/ImplementationContrasts.md that don't (I think) already have images:

racket scsh sisc foment scm ypsilon nexj jscheme ksi sigscheme shoe mini-scheme scheme9 rscheme s7 unlikely siod bdc xlisp rep elk umb llava sxm sizzle lmu dfsch inlab oaklis

Links to their home pages can be found at the above link.

I would say the Racket REPL has the highest priority: only the current version really matters here, though perhaps both standard Racket and Racket CS are worth having. SCM is important because it provides full access to SLIB, which has many good ideas in it that haven't really been mined yet. Oaklisp is the most deviant Scheme: it branched off after R3RS, and represents a complete re-engineering of Scheme over an OO core. Other than these there is no priority as far as I am concerned: create images whenever you feel like it. New Schemes not on the above list are also of interest, of course.

Of those, we already have:

racket scsh foment scm ypsilon ksi sigscheme shoe scheme9 (we call it by its cond-expand identifier: s9fes) s7 unlikely siod rep elk dfsch oaklisp mini-scheme xscheme (aka xlisp) rscheme sizzle sxm umb

Java Schemes we are missing:

sisc nexj jscheme bdc llava

C Schemes we are missing:

lmu inlab

Note: the following are separate things:

• XLisp/XScheme, a Scheme-like Lisp from David Betz (this is what's usually meant by both "xlisp" and "xscheme"). By appearances, "XLisp" and "XScheme" were released separately, but are much the same codebase; XLisp came earlier.
• XScheme, a version of STk that is unrelated to the XScheme by David Betz.

TODO:

• make sure we have tarballs for all of the above in lambdaconservatory/scheme-release-archive.
• also find any github mirrors for them.
