Shelling

Hi.
I need to write a set of shell scripts and I would really like to do it with a lisp.  Is that a use case for guile or should I move towards scheme/scsh?

hello Tom,
i use sometimes guile as a shell script, your file should start with:

#!/usr/local/bin/guile -s
!#

and after the scheme code
for example :

(define stderr (current-error-port))

; parse the input file from command line
(define cmd-ln (command-line))
(define args (cdr cmd-ln))

(when (member "--help" options)
....

etc

regards,
Damien

Not discouraging you from gash, but babashka is pretty good for this

i did not understood you where searching a shell in scheme...
so going further it seems to exist a sort of terminal in scheme too:

it is for Kawa scheme not guile, but i never test it, i can not provide any
feed back....

Hi Tom,

I do write my shell scripts in Guile. For added nicety, I usually deploy
these scripts using Guix's G-expressions. This lets you easily manage
the dependencies of that script, and deploy to remote machines
effortlessly. See
https://systemreboot.net/post/deploy-scripts-using-g-expressions for
more details if you're interested.

Here's a more complex example of a guile script:
https://issues.genenetwork.org/topics/deploy/uthsc-vpn-with-free-software
This script connects to a university VPN. The script couldn't have come
together so nicely without Guile or Guix. The complete script itself is
at https://issues.genenetwork.org/topics/deploy/uthsc-vpn.scm

Cheers!
Arun
