nnn-service-type for guix home

[jgart]

Hi Guixers,

Does it make sense to add nnn's configuration to the bash-service-type or to
create a new service altogether?

nnn is configured by setting environment variables:

I had originally proposed an nnn config for guix-home-manager:

For environment variables I think the best way is extending
'home-environment-variables-service-type' [1].  This approach could
configure nnn for not only for Bash, but e.g. Zsh.

Ah, thanks.

So, something like this?

(simple-service 'nnn-service-type
		home-environment-variables-service-type
		`(("NNN_BMS" . "d:$HOME/Documents;D:$HOME/Docs archive/")
          ("NNN_SSHFS" . ,(string-append sshfs "-o reconnect,idmap=user")) ; reference sshfs from store somehow
          ("NO_COLOR" . 1)
          ...))

            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

According to [1] this should be something like:
--8<---------------cut here---------------start------------->8---
(simple-service 'some-useful-env-vars-service
                home-environment-variables-service-type
                `(("NNN_SSHFS" . ,#~(format #f "~s"
                                            (format #f "~a -o reconnect,idmap=user"
                                                    #$(file-append sshfs "/bin/sshfs"))))))
--8<---------------cut here---------------end--------------->8---

which will be evaluated to:
--8<---------------cut here---------------start------------->8---
$ guix home build home.scm
/gnu/store/...-home

$ grep -RF NNN_SSHFS /gnu/store/...-home/
/gnu/store/...-home/setup-environment:export NNN_SSHFS="/gnu/store/...-sshfs-2.10/bin/sshfs -o reconnect,idmap=user"
--8<---------------cut here---------------end--------------->8---
