If you have some example of guix home profile that use dotfile manager
i'm interested :)
I'm planned to use chezmoi with pass (https://www.chezmoi.io/) in go
that use git to version file.

IIUC you can use Guix home directly and dispense with chezmoi.  However,
I did not know chezmoi before so there might be a use-case that is not
covered by Guix home, in principle though, Guix home is itself a dotfile
manager.

The only things holding me back at the moment is two things :





b) "password / secrets" management ?

Thanks,  in fact when i see *guix home* that was my first intention (like home-manager in nix). a) doom emacs flavour, how to manage the fact that doom use straigt.el to maintain packages I suppose i only save the .doom.d and ignore the .emacs.d that contain all packages downloaded by .doom.d/init.el and config.el There are two things, file to directly encrypt (like ssh key) and password to hide into configuration file (templating) b.1) So, that need to encrypt/decrypt more or less "on-the-fly" the files using gpg/yubikey or age like yadm ( https://yadm.io/docs/encryption ) or chezmoi (https://www.chezmoi.io/user-guide/encryption/gpg/) do ?

Actually I have no idea how to do that with guile / guix home for b.1 / b.2





I suppose guix home work well with guix on top of ubuntu ?

Best.

b.2) And for templating, like replacing ${mypassword} into some configuration file by getting info stored into password manager like "pass", i also don't know how to do that. c) synchronization of my .dotfiles between two different OS/System : Ubuntu (home) / Guix (work & home) Lot of people use Ubuntu in my work environment, so i need to maintain some sort of compatibility between both systems for my dotfile (before everyone use guix in 2030 ? :D).

  I use it for example to manage my Git config, Emacs config and
others.  The manual has a chapter about it:

https://guix.gnu.org/de/manual/devel/en/html_node/Home-Configuration.html#Home-Configuration

A simple example would be the following:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu home)
              (gnu home services)
              (gnu home services shells)
              (gnu services)
              (gnu packages admin)
              (guix gexp))


(home-environment
  (packages (list htop))
  (services
   (list
    (service home-bash-service-type
             (home-bash-configuration
              (environment-variables
               '(("HISTFILE" . "$XDG_STATE_HOME/bash_history")))))

    (simple-service 'git-config
                    home-files-service-type
                    (list `(".gitconfig"
                            ,(plain-file "gitconfig"
                                         "[user]
        email = daniel.meissner-...@ruhr-uni-bochum.de
        name = Daniel Meißner
")))))))
--8<---------------cut here---------------end--------------->8---

This would create a home-environment with the package ‘htop’, a bash
configuration that sets the HISTFILE env var as well as the .gitconfig
file with the above contents.  You can test this environment using:

   guix home container test-home.scm

This spawns a shell where your home environment is set up as specified
but using a container.  So your actual home directory is not modified.
You don’t have to embed all your config files inside the Scheme file
directly.  You can also load from other files, for example, you could
replace the ,(plain-file ...) call with a ,(local-file "gitconfig.txt")
which would use the contents of the file gitconfig.txt which lives next
to your Scheme file for the generation of the .gitconfig file.

Best
