SLIB (full/general) in Kawa?

[Sudarshan S Chawathe]

Does anyone have any suggestions for getting SLIB working in Kawa?

I mean the full/general SLIB distribution, not only the few parts that
are already in Kawa.  When I try to include SLIB's kawa.init file, I get
errors that seem related to the use of colons in SLIB identifiers.  In
particular, I thought I'd check if someone had SLIB running before
getting in too deep. (I'm also not sure if it is possible to "escape" a
colon to at least enable a very hackish "search and replace" kind of
workaround by modifying a local copy of the SLIB sources.)

I found an old thread/bug-report in the old Savannah repository:

  http://savannah.gnu.org/bugs/?19263

but nothing specific in the current Gitlab repository and in general am
unsure of the current state of things on this front.

I'll also take the occasion to say a heartfelt thanks and best wishes
for the new year to all of the Kawa community.

One possibility is to use the --r7rs command-line option:
https://www.gnu.org/software/kawa/Options.html#Options-for-language-selection

You can escape a colon either by surrounding it with vertical bars,
or by prefixing it with a backslash (both methods come from Common Lisp):

'|ab:cd| (or 'ab|:|cd) or 'ab\:cd

Thank you!

Thanks for the quick help.  I was able to make some progress using the
r7rs option, which I had forgotten about.  It means using the (invoke
foo 'bar baz ...) instead of (foo:bar baz ...) but I could probably get
used to that quite easily.

That's very good to know; I'll plan to try this alternative a bit later.
