Hi, and sorry for the delay!
Konrad Hinsen <konrad.hinsen@fastmail.net> skribis:

I have some comments regarding style and how to deal with multiple
scripts, but I think we’re pretty much there.

Should be: [@var{file} @var{args}@dots{}]
The square brackets show it’s optional.

“When one or more @var{file} argument is provided, each @var{file} is

To avoid car/cdr (info "(guix) Data Types and Pattern Matching"), I
suggest something along these lines:
(define scripts ;plural, no?
(reverse
(filter-map (match-lambda
(('script . script) script)
(_ #f))
opts)))
> + (define script-file
> + (let ((file (car script))
> + (directory (getcwd)))
> + (canonicalize-path
> + (cond ((string-prefix? "/" file) file)
> + (else (string-append directory "/" file))))))
I think we can just use file names as they arrive, without attempting to
canonicalize them or anything.

> + ;; Run script
> + (save-module-excursion
> + (lambda ()
> + (set-program-arguments (cons script-file (cdr script)))
> + (set-user-module)
> + (load script-file))))
=> (for-each load scripts)
> +cat > "$tmpfile"<<EOF

Rather:
#!$(type -P env)
This will ensure it works even in Guix build environments.
Could you send an updated patch?
Thank you!
Ludo’.
