I tried to bump the pinned Racket version in racket2nix from 7.1 to
7.2, and I ran into issues:
raco setup: 3 making: /nix
open-output-file: cannot open output file

The "fediverse" means the federated (decentralized) social web.
And Spritely, as I've said here recently, is a series of demos
and writeups which show how to "level up" the fediverse with
some new ideas to make it more powerful and resilient.
I just finished writing the documentation for Spritely
WOW. I finish read the doc about #:final
That is so beatiful thing. Thank you to you three

Thanks for the feedback!
I will study this code and make more functional

Well, if you call `(exit 0)`, your Racket program really will exit with
code 0 without doing anything else: the function `exit` never returns, so,
in your case, `execute` never returns, `refine-main` never returns, and
Rackunit never gets a chance to look at any output it may or may not have
writte
Thanks a lot.
Sorry about the simple error.

Your mistake is in the above line. You want to write refine-main not

(define (refine-main)
(display next-string) ;;feito
(set! next-command (shell-parser (my-read-line))) ;;TODO my-read-line

This is refine-main
"shell-parser" is just a PEG-based parser, that return a struc
I went ahead and added some info on the difference between Racket and
Python appends to https://github.com/racket/racket/wiki/Python-to-Racket .
Sorry to whoever for the salvo of poorly documented revisions.

I've written and use a `find-executable-path*` inspired by Emacs'
`exec-path-from-shell` (which I'm pretty sure I learned about from Greg on
this list) that gives the same API as `find-executable-path`, but with a
special case for Mac OS:
https://docs.racket-lang.org/adjutor/Experimental.html#%28pa
Well, there's no imediate return, i need to type exit 0 to finally the test
works
I am using read-line to read input. Today later I will post more code(of
refine-main).
Thanks

I don't know what `refine-main` does, but this simple version works for me:
#lang racket
(require rackunit)
(define (refine-main)
(display (read-line))) ;echo
(check-equal?
(with-output-to-string
