GnuPG-related options assume that "pinentry_mac" package is installed about dotfiles HOT 4 CLOSED

The dotfiles.pinentry-mac module is something I used in the past to create a symlink to pinentry_mac in /usr/local/bin.

https://github.com/midchildan/dotfiles/blob/9128258ef19e93818b51fc7258aeb1152f7857bb/home/.config/nixpkgs/home.d/dotfiles/modules/pinentry-mac.nix

from dotfiles.

The gnupg module that you referenced will actually work without any additional configuration. While pinentry_mac won't be available in PATH or ~/Applications, it'll be present in the Nix store.

Here's a simplified version of the relevant configuration:

home.file.".gnupg/gpg-agent.conf".text = ''
  pinentry-program ${pkgs.pinentry_mac}/Applications/pinentry-mac.app/Contents/MacOS/pinentry-mac
'';

When Home Manager sees this, it builds a derivation similar to the following:

pkgs.writeTextFile {
  name = "gpg-agent.conf";
  text = ''
    pinentry-program ${pkgs.pinentry_mac}/Applications/pinentry-mac.app/Contents/MacOS/pinentry-mac
  '';
}

Nix sees that this derivation depends on pkgs.pinentry_mac, and instantiates it in the Nix store. ${pkgs.pinentry_mac} is also replaced with the store path.

The key here is that there are other ways to use a package other than including it in home.packages.

Oh, that was not apparent to me. Thank you for explaining that.

I'm not sure that I have any other reason to refer to the pinentry-mac program other than for GnuPG to prompt me, so perhaps it being present but sort of "hidden" would be enough.

I confirmed that yes, pinentry-mac is available, in one case at a path like /nix/store/h0j374ylb8g411sv9wnb55859v6fq2n2-pinentry-mac-1.1.1.1/Applications/pinentry-mac.app/Contents/MacOS/pinentry-mac.
