Would it be possible to extend this to React Native [1], so we can write mobile apps in Racket?

Got it. In other words: "Urlang is a Racket flavoured S-expression syntax for Javascript" Thank you for your explanation - still seems like a good fit for one of my projects (as I needed something more lightweight than Whalesong) so I will try it out shortly.

Hi Greg, Think of Urlang as JavaScript with s-expression syntax. The core urlang language includes constructs that mirror JavaScript almost one-to-one. So Urlang is not "Racket to JavaScript compiler". There are few miniscule differences: - functions support optional arguments - The = operator generates === in JavaScript - if will only count the false value as false (zero is not considered to be true) That said: Urlang does support macros, which means you can write constructs that expand into core Urlang. In urlang/for you will find a Racket-ish for constructs. That is for, for*, for/sum, for*/sum etc https://github.com/soegaard/urlang/blob/master/urlang/for.rkt In urlang/extra you will find some often used macros: These constructs can be used as expressions: ; (begin0 expr statement ...) ; (when test statement ... expr) ; (unless test statement ... expr) ; (cond [test statement ... expr] ...) ; (case val-expr clause ...) ; where clause is [(datum ...) statement ... expr] ; or [elsestatement ... expr] ; (letrec ([id val-expr] ...) statement ... expr) ; (let* ([id val-expr] ...) statement ... expr) ;; These constructs can be used as statements: ; (swhen test statement ...) ; (sunless test statement ...) ; (scond [test statement ...] ...) https://github.com/soegaard/urlang/blob/master/urlang/extra.rkt We are working on making some more examples. /Jens Axel -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
