[racket-users] R7RS

Does anyone know of a summary of R7RS-Small changes relative to R5RS (not relative to R6RS)? (I'm aware of "http://andykeep.com/SchemeWorkshop2015/papers/sfpw1-2015-clinger.pdf;, which addresses a different question.) -- You received this message because you are subscribed to the Google

Re: [racket-users] Re: Online IDE’s for Racket ?

I came across some old posts on compiling Racket for the web, but I was wondering if there was any recent activity on this. Has anyone ever compiled Racket (including DrRacket) for the web -- i.e. with Emscripten? (I know about things like Whalesong and RacketScript. But I don't think these

Re: [racket-users] Re: Racket Mode documentation

That also looks cool! Definitely a lot of overlap. Maybe some differences: - I'm documenting Emacs major modes (an "app" vs. a lib). So my doc is less concerned with example code that ought to be tested. More concerned with stuff like showing default key bindings. - I wanted the README to

If `define-values` is not strictly required, here's a more syntax-case-y recursive version: (define-syntax (aux stx) (syntax-case stx () [(_) #'(begin)] [(_ (var val) . rst) (identifier? #'var) #'(begin (define var val) (aux . rst))] [(_ var . rst)

this is pretty cool Greg! I, too, had a brief excursion into documenting with Org. It still needs work, but here is an org-source that can be executed to generate the REAME.org
