Calling gpg encrypt inside mixed-text-file

Calling gpg encrypt inside mixed-text-file

Hi list

In a system configuration I won't to add a password file from a gpg 
encrypted file in the following manner:

(service radicale-service-type
			      (radicale-configuration
			       (config-file (mixed-text-file "radicale.conf" "
[auth]
type = htpasswd
htpasswd_filename = " (local-file "my-password.gpg ") "
htpasswd_encryption = plain
"))))

This obviously does not work, but how would I achieve to call gpg 
--decrypt --quiet inside the mixed-text-file?

Best

You'll need two things; ``computed-file'', and the ``(ice-9 popen)'' standard
library module. ``computed-file'' allows you to build a file-like object from
arbitrary code. Have a look here for an example from my configuration,

  https://git.sr.ht/~unmatched-paren/conf/tree/root/item/home.scm#L168

which removes all ``//'' comments from ``waybar.json'' before writing the
result to the store path.

Also see the Guix and Guile manuals on these two subjects,

  ``(ice-9 popen)'': https://www.gnu.org/software/guile/manual/html_node/Pipes.html
  ``computed-file'': https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html#index-computed_002dfile

Thanks for your pointers, will try if I can fiddle something together!
