haskell-process file not found in haskell-mode

Question

I'm trying to follow the haskell wiki to set up emacs to program haskell. I'm using haskell mode, and that seems to be working and okay, but now I try to generate haskell tags to be able to open a file with the M-. shortcut. I installed hasktags and haskell-mode as described here : http://www.haskell.org/haskellwiki/Emacs/Project_navigation. However, when I try to generate the tags through M-x haskell-process-generate-tags I get a 'not found' error. I found a post on stack overflow about this, How do I set up haskell-mode to generate tags?, which described my problem and solved it by loading haskell-process from .emacs.d/el-get/haskell-mode/haskell-process.el as path.

However, I'm on Ubuntu, and I installed the haskell-mode (and haskell-platform and emacs of course) through aptitude, and that didn't seem to contain this haskell-process.el file mentioned in that post. I then tried to download the haskell-mode through el-get, and that didn't include the haskell-process file either.

So, my question is, am I correct in assuming that I need the haskell-process file to be able to generate the tags, and if so, where can I get that file? I think I saw it in the git repo of haskell-mode, and I can of course pluck it out and put it in my directory, but I've got the feeling that if I have to resort to that, it means I'm doing something wrong.

Answer 1

Emacs packages are usually outdated in Debian-based distributions, and I think, that Ubuntu still have very old version of haskell-mode. It's better to install haskell-mode via package.el, that is bundled together with Emacs. Fresh versions of haskell-mode for package.el are available via MELPA. The similar advice I can give for other Emacs packages ;-)
