Re: [racket-users] Unbound identifier error with syntax transformer that uses syntax-generating helper procedure

Thanks, that explanation helped. I had gaps in my knowledge. I also ended up daisy-chaining yet another submodule nested within the first, to require it both normally and for-template due to braid-shaped phase dependencies. Nothing seems to have gone wrong. On Tuesday, May 8, 2018 at

Re: [racket-users] Unbound identifier error with syntax transformer that uses syntax-generating helper procedure

The short answer is that you need a (require (for-template racket/base)) in your utilities submodule: (module utilities racket/base (provide compile-test) (require (for-template racket/base)) (define (compile-test) #`(lambda (i) (displayln `(input: ,i) But this answer

[racket-users] Unbound identifier error with syntax transformer that uses syntax-generating helper procedure

Hi, I'm having trouble writing a syntax transformer that uses a syntax-generating procedure defined elsewhere. When the procedure is defined locally, everything is fine. When the procedure is defined outside the transformer, I have to do a dance to make the procedure visible at the right

[racket-users] question on quasisyntax/loc

I'm having trouble understanding quasisyntax/loc in some cases. If I have the following example code: #lang racket (define here #'here) (define stx0 (syntax/loc here #'Y)) (define y #'Y) (define stx1 (quasisyntax/loc here #,y)) (displayln (format "here : line ~a" (syntax-line here)))

[racket-users] Provide form generator

Hi folks, I developed a provide form generator to take the pain out of writing module headers: https://github.com/dexterlagan/provide-generator It works great, but I wonder if there wouldn’t be a simpler and more standard way to write this. My original idea was to parse the module syntax

Thanks Matthias. I'm fairly new to Racket, and I thought the provide form was just a way to indicate which functions to expose. I'll look into it. Dexter -Original Message- From: Matthias Felleisen Sent: Tuesday, May 8, 2018 12:11 PM To: Dexter Lagan

Re: [racket-users] what do people use for number formatting?

My ancient, half-finished R4RS Scheme number-formatting library is still used by at least one program.  When I moved that library to the Racket new package system, I made an effort to deprecate it. But anyone improving modern-day idiomatic Racket formatting might want to take a quick peek at

Re: [racket-users] Provide form generator

Neat. Keep in mind that the API of a module should be considered a specification (purpose, signature) that the module body (generated later) lives up to. No, this is not how we always work in practice because software evolves, but that is the principle. > On May 8, 2018, at 11:21 AM,

Re: [racket-users] Provide form generator

Thank you for contributing.  A few suggestions: * You probably want to put your unit tests, and the `(require rackunit)`, inside `(module+ test ...)` forms.  That makes it better as a library or program, and also is what Racket expects for testing. * You can make this a full-fledged Racket

Does anyone have experience using Markdown format for embedded documentation in Racket, including generating Scribble docs (to be the most cooperative Racket citizen)? How well has that worked, in practice?  Do you end up having to kludge things, and do you find you can't express things you
