You need to have guix in the %load-path variable, then load the module
containing `specifications->manifest`. The easiest way is to just run 

    guix repl

from a terminal (or shell in emacs) to get a repl.


Or if you want to use geiser you can use guix shell to setup the right
environment and launch emacs

    guix shell guix guile --emacs

Once you got the correct load path setup you can just import the module
containing `specifications->manifest` in the repl.

    (use-modules (gnu packages))

To find which module that contain that procedure, you can search for it
in the guix manual and it will say just above it what module it
contains.

Alternative you can clone the guix repo and call something like
consult-ripgrep in emacs on it with the search term
#specifications->manifest#define

The guix manual will also describe how to setup emacs for hacking on
guix [0] that might be useful.

I hope that helps.
