Metal Mercury Mode: Library not found

Metal Mercury Mode: Library not found

[Volker Wysk]

Hi

I'm trying to install the Metal Mercury Mode (for the Mercury
programming language) and get this message on startup:

   Warning (initialization): An error occurred while loading 
   `/home/v/.emacs':                                                  
               
   File is missing: Cannot open load file, No such file or directory, 
   dash                                                              
  
I've added this to my .emacs, like it's described in the M.M.M.
documentation:

   (add-to-list 'load-path "~/.emacs.d/metal-mercury-mode")
   (require 'metal-mercury-mode)

The files are in place:

   desktop ~ $ ls -l ~/.emacs.d/metal-mercury-mode/
   insgesamt 72
   -rw-r----- 1 v v 35147 Jul 20 20:58 LICENSE.md
   -rw-r----- 1 v v  8718 Jul 20 20:58 mercury-font-lock.el
   -rw-r----- 1 v v  8277 Jul 20 20:58 mercury-indentation.el
   -rw-r----- 1 v v  4975 Jul 22 13:11 metal-mercury-mode.el
   -rw-r----- 1 v v   941 Jul 20 20:58 README.md

Somehow the metal-mercury-mode isn't found. Even though
"~/.emacs.d/metal-mercury-mode/" is in the load path...

So how to find out what's going wrong?

Regards,
Volker

It seems Metal Mercury Mode requires dash which is another 3rd-party
package.  So you need to install that as well.  You can install it from
MELPA using the package manager.

That's the solution, it works now. It's the package "elpa-dash" on my
Ubuntu system.

Thanks!

You can also install it from GNU ELPA, of course.

Gosh, obviously I've checked list-packages first to determine it was
also listed for GNU ELPA but it isn't.  If you have MELPA as an
additional archive, aren't the ELPA versions listed anymore if the
package is provided by both?  I'm pretty sure packages used to be listed
for both but usually the MELPA one "won" because of the astronomical
version number.
