Guix Environment Best Practices: Shell Hooks, Creating directories, and More

[jgart]

Hello Guix!

Could someone share an example or advice on how to currently achieve the following nix shell hook with guix environment/manifests/gexps/...: 

# define shell startup command
  hooks = ''
    # this allows mix to work on the local directory
    mkdir -p .nix-mix
    mkdir -p .nix-hex
    export MIX_HOME=$PWD/.nix-mix
    export HEX_HOME=$PWD/.nix-hex
    export PATH=$MIX_HOME/bin:$PATH
    export PATH=$HEX_HOME/bin:$PATH
    export LANG=en_US.UTF-8
    export ERL_AFLAGS="-kernel shell_history enabled"
  '';

in mkShell {
  buildInputs = inputs;
  shellHook = hooks;
}

Taken from this blog post on using nix shell for developing elixir:

Any help is greatly appreciated.

I believe in guix land this is best achieved with

#+BEGIN_SRC
guix environment -m environment.scm
#+END_SRC

Assuming the project that you are working on has such an
"environment.scm" file.

guile-haunt has "package.scm" file that does something like this:
