Yes that would be ideal. One day.

This is really awesome and saved the day for me. It works well! I read
up a bit on the above because wasn't that familiar with some of the
direnv magic above.
use guix --ad-hoc address@hidden gcc-toolchain pkg-config libxml2 libxslt
layout ruby
Thanks a lot! This setup also works nicely with emacs-direnv.
However with an old puppet 3 project using ruby 2.1.10 setup using the below I
get these weird
errors. Any idea?
$ cd ~/src/fnb/puppet-main
direnv: loading .envrc
direnv: using guix --ad-hoc address@hidden gcc-toolchain pkg-config libxml2
libxslt

$ cat .envrc
use guix --ad-hoc address@hidden gcc-toolchain pkg-config libxml2 libxslt

Was getting similar issues when running bundle there.
