Well, if you don't want to put the content of
files/waybar/modules-mic.sh file inside a Scheme string, then you need
to read the file to a string, e.g.:
--8<---------------cut here---------------start------------->8---
(simple-service 'shellcheck-wrapper
home-files-service-type
(list `("local/bin/shellcheck"
,(computed-file
"shellcheck-wrapper"
#~(begin
(use-modules (ice-9 rdelim))
(with-output-to-file #$output
(lambda ()
(display #$(with-input-from-file "/tmp/foo" read-string))))
(chmod #$output #o555))))))
--8<---------------cut here---------------end--------------->8---
Note that it's just an example which you should change according to your
needs. ;-) Also, it creates not an executable but a symlink to an
executable in a store, which I missed in a previous answer.
