Subject: [home] Use guix repl as the Geiser Guile REPL backend.
X-Git-Url: https://git.ekhem.eu.org/?a=commitdiff_plain;h=0006bb59f4e0640e61ea803da6accf160cb0638c;p=guix.git

[home] Use guix repl as the Geiser Guile REPL backend.

Set geiser-guile-binary to ("guix" "repl") so the Geiser REPL
starts inside the Guix execution environment, giving it access to all
Guix-installed Guile libraries.
