It has not been packaged, but it should not be difficult to add a
variant for the stable version by inheriting from the “lilypond” package
definition and overriding the version and source fields. You can add a
module defining such a package to your GUIX_PACKAGE_PATH (see the manual
for more information about how to use this feature).
Something like this might work (untested):
--8<---------------cut here---------------start------------->8---
;;; This file is not part of GNU Guix but is distributed under the same
;;; license as GNU Guix.
(define-module (custom packages variants)
#:use-module (guix utils)
#:use-module (guix packages)
#:use-module (guix download)
#:use-module (gnu packages)
#:use-module (gnu packages music))
(define lilypond-stable
(package (inherit lilypond)
(version "2.18.2")
(source (origin
(method url-fetch)
(uri (string-append
"http://download.linuxaudio.org/lilypond/sources/v";
(version-major+minor version) "/"
name "-" version ".tar.gz"))
(sha256
(base32
"01xs9x2wjj7w9appaaqdhk15r1xvvdbz9qwahzhppfmhclvp779j"))))))
--8<---------------cut here---------------end--------------->8---
After putting this in $GUIX_PACKAGE_PATH/custom/packages/variants.scm
and setting GUIX_PACKAGE_PATH you should be able to install it with
guix package -i lilypond@2.18
Hope this helps!
