Marmalade support

[rassie]

Marmalade is an alternative repository for package.el located at http://marmalade-repo.org/. Would be nice to have its explicit support in el-get. Implicit support is already possible by adding (add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages")) to init.el.

Interesting; for this to work you actually need the version of package.el from the emacs 24 repository: http://repo.or.cz/w/emacs.git/blob_plain/HEAD:/lisp/emacs-lisp/package.el

The version of package.el on tromey.com doesn't have a package-archives variable.

(setq el-get-sources 
  '((:name package 
     :url "http://repo.or.cz/w/emacs.git/blob_plain/HEAD:/lisp/emacs-lisp/package.el")))

Also, I note that you have to add a trailing slash to that URL or it breaks:

(add-to-list 
  'package-archives 
  '("marmalade" . "http://marmalade-repo.org/packages/"))

I further note that fully using package.el from emacs24 requires one more elisp file, package-x.el from the same repo, and that it doesn't include the original elpa package archive by default. So you may also need:

(add-to-list
'package-archives
'("tromey" . "http://tromey.com/elpa/"))

One of you should probably send us the full working new recipe of package.el, using the Emacs24 code and with support for tromey and marmalade archives. I'll be happy to apply such a change.

Also, has some testing been done wrt the packages.el from Emacs24 working fine with previous Emacs version, at least emacs 23?

[taoeffect]

Yeah, it'd be nice to make sure that this works emacs 23.

I'm using this recipe to get package.el working with emacs 23, the issue is that 'package-subdirectory-regexp' is not defined in package.el, I don't know where it went, it used to be there :) Anyway this recipe would work as a hack for emacs versions prior to 24. Marmelade support could be added in the post-init hook. I also commented the same snippet on #209

(:name aj-package
               :type http
               :url "http://repo.or.cz/w/emacs.git/blob_plain/HEAD:/lisp/emacs-lisp/package.el"
               :features package
               :post-init (lambda ()
                            (unless (boundp 'package-subdirectory-regexp)
                              (defconst package-subdirectory-regexp
                                "^\\([^.].*\\)-\\([0-9]+\\(?:[.][0-9]+\\)*\\)$"
                                "Regular expression matching the name of a package subdirectory. The first subexpression is the package name. The second subexpression is the version string."))
                            (setq package-archives '(("ELPA" . "http://tromey.com/elpa/")
                                                     ("gnu" . "http://elpa.gnu.org/packages/")))
                            ;; Don't init, elpa packages installed by el-get is initialized from loaddefs
                            ;;(package-initialize)
                            ))

I merged your post-init into the package24 recipe from el-get, and added the marmelade URL in package-archives. Is it ok enough this way?
