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,

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)'':
