2009/1/22 Peter Verswyvelen I have a silly problem.

I'm using Emacs with the Haskell mode extension on Windows

I have a source file in say

c:/foo/src/main.hs

main.hs is importing some other modules in that same src directory

When I invoke GHCi from within Emacs, the first thing it does is

:cd c:/foo

and then

:load "src/main.hs"

But of course GHCi won't find the imported modules now, since the current directory is wrong.

If I type in GHCi

:cd src :load "main.hs"

then it compiles fine.

Does anyone have an idea why Emacs or the Haskell mode is switching to the parent directory of src instead of src itself, and how to fix this?

Thanks a lot, Peter

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? On Fri, Jan 23, 2009 at 1:09 AM, Andrew Wagner wrote:

Hmm, strange. This doesn't appear to fix my problem. Perhaps I have something bigger broken locally :(

Hello John, Thursday, January 22, 2009, 8:50:39 PM, you wrote: thanks, support of over-internet and intranet collaboration looks very promising these days (even if not saying about ability to highlight error place ;) btw, i was unable to download mp4 video from http://vimeo.com/1653402 (online players doesn't work in my browser)

Not that you're looking to switch editors, but if you want something a little more hassle-free:

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. De Goes wrote:

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.

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?
