Great, thanks David, that did the trick.
And someone might want to fix the "racket --help" output, if you ask me.
Happy holidays!

Re: [racket-users] racket -m from commandline

2022-12-17 Thread David Van Horn 
You likely want to also use the -t option so that the module is required.
Here's an example:

% cat try.rkt

#lang racket

(provide main)

(define (main . args)

  (displayln (cons "HELLO:" args)))

% racket -tm try.rkt there

(HELLO: there)

[racket-users] racket -m from commandline

2022-12-17 Thread whuk...@gmail.com 
racket --help says:

  -m, --main
 Call `main` with command-line arguments, print results

but I cannot get this to work. All I get is 

main: not defined or required into the top-level environment

in all (to me) conceivable variants. Could anyone provide an actually 
working example?
Please don't recommend books or so, I have a life.

Thanks.
