haskell-mode does not work in emacs 24.4.1 in archlinux

[adrianor]

I have installed haskell mode for emacs in archlinux via:
sudo pacman -S emacs-haskell-mode
No problem so far. On my init.el file I have the load:
(load "/usr/share/emacs/site-lisp/haskell-mode/haskell-mode.el")
However, if I do "M-x haskell-mode" I get:
Symbol's value as variable is void: haskell-font-lock-choose-keywords
And also my haskell code is not highlighted as it is suppose to be.

This sounds like a packaging issue to me; is the haskell-font-lock.el file being installed?

[adrianor]

Maibe it was not installed. I removed the application and clone the repo using git.
I followed the steps described here https://github.com/haskell/haskell-mode and everything works nicely.

So yes, there's a problem with the pacman package.

[fosskers]

Try emacs-haskell-mode-git from the AUR.

[purcell]

Yep, or you can M-x package-install it from MELPA.

[gracjan]

Is this one solved for you, @adrianor?

[gracjan]

@purcell? @adrianor? Can we close this?

[purcell]

I think so, thanks. @adrianor can re-open it if it's still a problem.

[adrianor]

no problem, can be closed

Reopened.

I just got exactly the same issue, even archlinux and emacs version are
the same. BUT I did install haskell-mode via cask (melpa). I guess this
topic should be reopened.

[gracjan]

Michał, can you check what version is pacman installing for you?

[gracjan]

@adamczykm: Michał, can you check what version is pacman installing for you?

[adamczykm]

@gracjan You were too fast :). Melpa package didn't create autoload file, so I, going by usual convention, required haskell-mode.el. Requiring haskell.el instead fixed all of the issues.
So maybe the thread didn't have to be reopened, it's strange though that the 'name-mode.el' isn't the root file. Thanks.

[gracjan]

@adamczykm: pacman package sure contains haskell-mode-autoloads.el (does not contain haskell-mode-autoloads.elc, not sure if that is the convention or what is the point).

pacman package also contains a lot of '*.elc' files which is arguably not a good thing as that depends on exact emacs version present.

@adamczykm: Can you report a bug to archlinux packager that did package haskell-mode?

[adamczykm]

I didn't use pacman. I used cask https://github.com/cask/cask

[gracjan]

Comfirmed, melpa package does not have autoloads inside.

Should melpa generate autoloads when installing? Should CASK generate autoloads when installing?

What is the convention here?

[purcell]

package.el generates autoloads at the point when the package is installed.

[gracjan]

Why does cask not do it? Should cask be doing it?

[purcell]

Not sure. I thought that cask just uses package.el and the package-build.el which provides the machinery for MELPA.

[gracjan]

Are autoload generated from *.el or there is a need for a special declaration file?

[purcell]

They're generated from the ;;;###autoload comments in the .el files, via the standard update-directory-autoloads function.

[gracjan]

@adamczykm: I load haskell-mode-autoloads.el not haskell-mode.el, like this:

(add-to-list 'load-path "~/Sources/haskell-mode")
(require 'haskell-mode-autoloads)

and then everything works.
