'egg-source-url' did not return the URL, but the quoted expression. This did break the updater, which expects the URL as a string. * guix/import/egg.scm(egg-source-url): Remove. (egg->guix-package)[egg-content]: Use quoted expression directly. (latest-release): Call egg-uri instead of egg-source-url.

;;; Commentary:
|

;;;
|
||
;;; (guix import egg) provides package importer for CHICKEN eggs. See the
|
||
;;; official specification format for eggs
|
||
;;; <https://wiki.call-cc.org/man/5/Egg%20specification%20format>.
|
||
;;;
|
||
;;; The following happens under the hood:
|
||
;;;
|
||
;;; * <git://code.call-cc.org/eggs-5-all> is a Git repository that contains
|
||
;;; all versions of all CHICKEN eggs. We look clone this repository and, by
|
||
;;; default, retrieve the latest version number, and the PACKAGE.egg file,
|
||
;;; which contains a list of lists containing metadata about the egg.
|
||
;;;
|
||
;;; * All the eggs are stored as tarballs at
|
||
;;; <https://code.call-cc.org/egg-tarballs/5>, so we grab the tarball for
|
||
;;; the egg from there.
|
||
;;;
|
||
;;; * The rest of the package fields will be parsed from the PACKAGE.egg file.
|
||
;;;
|
||
;;; Todos:
|
||
;;;
|
||
;;; * Support for CHICKEN 4?
|
||
;;;
|
||
;;; * Some packages will specify a specific version of a depencency in the
|
||
;;; PACKAGE.egg file, how should we handle this?
|
||
;;;
|
||
;;; Code:
|
||
|
||
|
||
;;;
|
||
;;; Egg metadata fetcher and helper functions.
