Re: guix shell readline issue with R

[Edouard Klein]

Credit where credit is due, the shebang's idea comes from guix's manual.

You can also do the following:

#+begin_src bash
#!/usr/bin/env bash
# Autowrap self in guix shell
if [ -z "${GUIX_ENVIRONMENT:-}" ]
then
    guix shell YOUR DEPENDENCIES HERE -- "$0" "$@"
    exit 0
fi
ACTUAL CONTENTS OF THE SCRIPT HERE
#+end_src

Cheers !

Edouard
