I made it work with PLT scheme 4, more or less - using enter! in a command-line mzscheme, at least. (boot) works, (opt (parse-ometa “a ::= ‘a’ => true;”)) works, I haven’t figured out how to parse actual data. See darcs repo at http://joyful.com/darcsweb/darcsweb.cgi?r=ometa-scheme;a=summary

Thanks for making your code available. I’m a Lisper interested in OMeta, so between your Scheme code and John Leuner’s Lisp port of the Squeak version (as mentioned above) I hope to get (a) my head around OMeta and (b) some Lisp code of my own that I understand.

I like your mention of extra (any?) error handling stuff, and the fact that your code is 803 lines of Scheme vs. 3000+ lines of Lisp and 5000+ lines of JavaScript… ;)

And now my question: I’ve downloaded the latest MzScheme, but it looks like your code won’t run in version 4 out of the box (not that I’ve used this particular box before).

If I want to study your code interactively, would I be best advised to download a slightly earlier version of MzScheme? Or should I hang on for the next release?

Thanks again,

John :^P
