Thanks for the quick response. I wouldn't have gotten as far as I have so far without your 'Fear of Macros' page, so thanks for that as well!

There is a form that defines a function and another form to call one. I may be missing something, but I didn't think I could use the name as valid syntax since this is the form that is creating it. If passing a symbol in would work then I could potentially change my lexer to do that instead of a string. > If the idea is that users will supply the name as a string like > "some-name", then yes your macro would need to do the > > (string->symbol (syntax->datum #'magic-name)) > > thing you already have -- but *also* convert that result back to syntax: > > (datum->syntax #'magic-name > (string->symbol (syntax->datum #'magic-name))) > > I tried this in my with-syntax and for some reason the identifier was still not visible to the code that is calling it, which is in the same module. Any ideas? These macros are part of a language and aren't used directly from normal racket code. Perhaps there is some added complexity there? -- Jonathan -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
