Re: [Haskell-cafe] Haskell mode for Emacs question
Interesting. I have a similar, but worse problem. For me, ':load'ing main.hs would fail to find the imported files.

On my Mac I've had the same problem. Commenting out lines (unless (equal default-directory root) (setq default-directory root) (inferior-haskell-send-command proc (concat ":cd " default-directory))) solved it for me.

Re: [Haskell-cafe] Haskell mode for Emacs question
mmm, it seems that the code is searching for the location of a cabal file and uses that as the current directory, assuming all source code is relative to that directory, instead of using the source directive in that cabal file.

Re: [Haskell-cafe] Haskell mode for Emacs question
It's too bad Visual Haskell was not continued, since a free version of the Visual Studio platform is available now. I felt Visual Haskell was very promising, like on the fly type inference with tool tips, code completion, built in Cabal support, etc... On Thu, Jan 22, 2009 at 6:50 PM, John A.

Re: [Haskell-cafe] Haskell mode for Emacs question
After emacs started your GHCi session, when you manually type :cd "the full path of the directory of your Main.hs" :load "Main.hs" Does it work then? Can you use GHCi from outside Emacs?

looks like a neath editor. too bad on windows you don't get anti aliased fonts (I guess it uses an old J2SE or something?) at first sight I was not able to find Haskell support in the freely downloadable version. is this available in the commercial version?

Re: [Haskell-cafe] Haskell mode for Emacs question
No, Haskell support in the free version too. However, you'll have to add the tools to compile .hs files in the "Tools" menu. You can pipe the output to directly highlight errors/warnings in the document (which is what's done in the screenshot below), because the editor understands what GHC errors/warnings look like.
