Is there a way to run guile function from command line

Question

So I have a simple file.scm file with following code in it:

#!/usr/bin/guile -s 
!#
(define (printer arg)
  (display arg))

I know you can execute it inside guile repl by doing a (load "file.scm"), and then by invoking the function like (printer "this").

Is there is any way to run that function through the command-line terminal such as guile "file.scm" (printer "this") ?

Answer 1

According to the manual, something like

guile -l file.scm -c '(printer "this")'

will work.

Answer 2

You could just use the -e flag

guile -e printer file.scm 1 2 3

Or better yet

#!/usr/bin/env -S guile -e printer
!#

(define (printer args)
  (display args))

and run as

./file.scm 1 2 3
