The spec code also references these links: http://matt.might.net/articles/implementation-of-regular-expression-matching-in-scheme-with-derivatives/ http://www.ccs.neu.edu/home/turon/re-deriv.pdf https://github.com/clojure/spec.alpha/blob/master/src/main/clojure/clojure/spec/alpha.clj#L1369-L1372 Similarly SheX the RDF validator I mentioned also appears to be influenced by this area; which finally clarifies a suspicion I'd had for a while... Section 9 of this paper also cites some other derivate implementations, e.g. Relax NG for validating XML: https://pdfs.semanticscholar.org/7b7f/770d2243247688befe98b3aed0ea70b15e15.pdf R. > Regards /Henning > > > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > --- > You received this message because you are subscribed to the Google Groups > "Clojure" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to clojure+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
