That was the fundamental concept I was missing. I don’t recall seeing that in the documentation, but now that I know I’ll search for that and see if I glossed over it somehow. -Kevin -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Macro generating macro question
Hi Kevin, When you are writing macro generating macros there are two levels of ellipsis. The outer one, which you can write as ... as normal and the inner one which you need to escape. You can escape it with (... ...). That looks odd to me, so I usually bind it to an identifier named ooo. #lang racket (require (for-syntax syntax/parse racket/syntax)) (define-syntax (make-id-macro stx) (syntax-parse stx [(_ id) (with-syntax ([name (format-id #'id "do-~a" #'id)] [ooo #'(... ...)]) #'(define-syntax (name stx) (syntax-parse stx [(_ parms ooo) #'(list parms ooo)])))])) (make-id-macro foo) (do-foo 1 2) See you on Racket Discourse. /Jens Axel Den ons. 24. maj 2023 kl. 06.27 skrev Kevin Forchione : > Hi guys, > I’m stumped.

Hi Kevin The most active places for ‘Racketeers’ is the Racket [Discourse]( https://racket.discourse.group/) and [Discord](https://discord.gg/6Zq8sH5) Please join us! See also https://github.com/racket/racket/wiki/Macros - in particular i think you may find what you are looking for in https://docs.racket-lang.org/syntax-parse-example/index.html (many who prefer email just use discourse in ‘mailing list mode’) Best regards Stephen On Wed, 24 May 2023 at 05:27, Kevin Forchione wrote: > Hi guys, > I’m stumped.

[racket-users] Macro generating macro question
Hi guys, I’m stumped. In a nutshell I want to write a macro that is passed an id and will produce a macro called id that can take variable arguments. I’m sure I’m overlooking something fundamental. The basic form below “works” if I don’t have ellipsis aver the variables, but that’s not what I’m after. Here’s an example that is obviously wrong, but is along the lines of what I’m looking for: #lang racket (require (for-syntax syntax/parse racket/syntax)) (define-syntax (make-id-macro stx) (syntax-parse stx [(_ id) (with-syntax ([name (format-id #'id "do-~a" #'id)]) #'(define-syntax (name stx) (syntax-parse stx [(_ parms ...) #'( list parms ...)])))])) Any help in this and explaining why it fails would be greatly appreciated. -Kevin -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
