Feature request: guess project from path and save somewhere

[Mikolaj]

A feature request (unless it's bug that only affects me): I'd like to avoid answering questions for each of the dozens of files in my project whether I like the file to be included in the current project. I suppose this can be guessed from the path or the cabal file. Alternatively or in addition, this information could be saved somewhere for future session, e.g, in the desktop file, if that makes sense.

Yes, +1! The same thing happens to me with haskell-interactive-mode and this is painful. It breaks the editing flow when suddenly Emacs starts asking questions when I'm saving a file. I tend to re-start Emacs often and get these questions very frequently.

I would favor that the Haskell mode would simply guess which project a file belongs to by searching for a .cabal file upwards from the file hierarchy from the loaded file until it finds a .cabal file.

I'm not so keen on trying to cache this information in session files. Better to try to guess this well enough so that no cached information is necessary.

I usually only ever have a single active cabal session active. I think in this case, guessing the right active project should be easier.

Apparently the feature works for others, see #124. Also, it now works for me if I load files into emacs manually, one at a time.

Could everybody interested verify that the problem persists if you use no symbolic links in the paths of the files edited with emacs? I can't reproduce it any more when I use direct paths, with no links, see #124. If that's the same for everybody, I guess we can try to improve the code to cope with symbolic links, but we can alternatively write this down in a FAQ or other docs and I'd be happy to close the issue then.

Moving to 13.7 milestone.

This issue has not seen activity for a very long time. Is this still something we should be concerned about?

[Mikolaj]

Oh, I'm sorry, it's long ago fixed. thank you!
