record-case?

record-case?

[Noah Lavine]

Hello,

I was just reading module/language/tree-il/compile-glil.scm, and I
noticed it used a construct called 'record-case'. It looked neat, but
I didn't see documentation for it in any of the obvious places in the
manual (the section on records or the pattern-matching section). Is it
public? If so, is there documentation somewhere?

Thanks,
Noah Lavine

Yes it looks like a cool thing, code for it is in
(use-moules (system base syntax)) 

There you see how it works ;-) But perhaps the author can point
to the pros and cons.

I find it limited and would rather add record matching support in
(ice-9 match), something I’ve been willing to look at for too long...

Said support is actually available upstream (in the ChibiScheme repo) so
it should be quite simple.

Thanks,
Ludo’.

Agreed, though perhaps a first step would be (after getting record
support into match.scm) making an implementation of record-case in terms
of ice-9 match. Should be simple.
