Hi, I have written a #lang, which works ok when it is in its own file. Now, I'd like to make it embedded through a macro such as '(my-lang ...)'
What I would like is essentially expand that: #lang racket ... standard racket source ... (my-lang ...) ... standard racket source ... to that: #lang racket ... standard racket source ... ... racket source expanded from my-lang ... ... standard racket source ... But there's a problem, because although the 'my-lang' macro will expand my-lang code to racket code, it must expand to a valid expression, i.e: (define-syntax (my-lang stx) #`(my-lang-expand (open-input-string (cadr (syntax->datum stx))))) could yield '(begin (define a 3) a)' while I would want '(define a 3) a' so that the 'a' from 'my-lang' becomes a valid top-level identifier in the whole (racket) program. I understand that this impllies that the '(my-lang ...)' macro would then modify its parent expression (the main program), so I guess that means breaking the normal expansion process. Is that possible? Is there a better way? Thanks! Raoul -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
