Melpa precedence over Marmalade about emacs.d HOT 9 CLOSED

Yes and no. Precedence is not directly supported by package.el, but there's a workaround -- see the "Customizations" section of the documentation on http://melpa.milkbox.net/

from emacs.d.

Thank you for the pointer. I have set (setq package-archive-exclude-alist '("marmalade" . slime)) as detailed there, to prevent the installation of package slime@marmalade, but it still gets installed instead of the melpa's one. Where am I getting it wrong?

from emacs.d.

Have you also installed and initialised melpa.el, as described on that page?

from emacs.d.

Sorry I can't make it work (I feel like a dufus.)

I installed melpa.el as described, and initialised it. Then evaluated (setq package-archive-exclude-alist '("marmalade" . slime)). Finally M-x package-install RET slime RET.

Still installing from marmalade. (I probably am a dufus).

from emacs.d.

Hang on, I think I misread your original message - sorry. If you have both Marmalade and Melpa in your package-archives list, then you shouldn't need to do anything further -- Melpa will always appear to have the highest-numbered package versions, so its packages will always have precedence over those from Marmalade.

So in this case you can ignore my advice about melpa.el, though it may prove useful to you at some point.

Given the behaviour you've reported, my guess is that you need to update your list of available packages. You can do this most easily by running M-x package-list-packages RET. The version of Slime listed there should then be the one from Melpa, which you can then install by pressing i then x.

Apologies for my confusion.

from emacs.d.

Alas, I run that command but no luck. the list of packages shows no sign of slime 20120501 (from melpa), but only the one installed by default, slime 20100404.1 from marmalade.

I was wondering , if that priority mechanism is already in place, why .emacs.d would download the marmalade one the first time anyway?

from emacs.d.

Wow... I'm really being an idiot today. I didn't even notice that this was filed as an "emacs.d" issue, and so I answered it as if it was a Melpa issue!

So the final answer is that this behaviour is according to my personal preferences, because I use the old Slime version in order to be compatible with Clojure.

If you want to change this in your fork, look at line 77 of init-elpa.el. There's a list of packages in that block of code, and if you remove "slime" from the list then re-evaluate the block of code, you should be able to see the Melpa version of Slime in the package list. :-)

(No guarantees that the rest of the emacs.d is compatible with that newer slime, though!)

Thanks for your patience,

Wonderful, it works perfectly now.

Your .emacs.d is indeed a treasure trove of interesting code.

Thank you so much for your help and all your time.
