Looking back at your code, it looks like `set-s-lst` should do more of its work at compile time, as opposed to run time.
Specifically, it *expands* into code that computes `key-val` (that code is within an #'). It should instead be computing that list at compile time, so that `set-s` can actually act on it. You'd want something like that: (define-syntax (set-s-lst stx) (syntax-case stx () [(_ id label lst-val lst-key) (let ([key-val (for/list ([key (syntax->list #'lst-key)] [val (syntax->list #'lst-val)]) #`(#,key #,val))]) #`(set-s id label #,key-val))])) Vincent On Wed, 13 Apr 2016 20:40:54 -0500, Héctor Mc wrote: > > I understand that struct is not collections of key-value, > in the code appear in this way for reference, even label. > The problem that I have is in the macro set-s in the > formation of the accesors to fields of structure. > > This generates (set-usuario-key! ..) instead of (set-usuario-nom! ..) > into with-syntax. > > -- > You received this message because you are subscribed to the Google Groups > "Racket Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to racket-users+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 "Racket Users" group.
