Previous: Automatic update, Up: Programmable and automated package definition [Contents][Index]
If you’ve started browsing the existing package definitions, you might have
noticed that a significant number of them have a inherit
field:
(define-public adwaita-icon-theme
(package (inherit gnome-icon-theme)
(name "adwaita-icon-theme")
(version "3.26.1")
(source (origin
(method url-fetch)
(uri (string-append "mirror://gnome/sources/" name "/"
(version-major+minor version) "/"
name "-" version ".tar.xz"))
(sha256
(base32
"17fpahgh5dyckgz7rwqvzgnhx53cx9kr2xw0szprc6bnqy977fi8"))))
(native-inputs (list `(,gtk+ "bin")))))
All unspecified fields are inherited from the parent package. This is very convenient to create alternative packages, for instance with different source, version or compilation options.
