Haskell as scripting language?
Is there a way to use haskell as scripting language in a) your own project? b) other projects such as vim (beeing written in C)? At the moment I'm interested, I don't have any real project..
For scenario (a) you can use hs-plugins and ghc
http://www.cse.unsw.edu.au/~dons/hs-plugins/
With hs-plugins you can get an "eval" command, or you can dynamically
load Haskell modules (from source or pre-compiled .o files).
GHC (>= 6.5) has an API that you can access from Haskell programs:
http://www.haskell.org/haskellwiki/GHC/As_a_library
I was wondering if the new GHC API gives you everything hs-plugins
does? If not will it ultimately do what hs-plugins does and replace
it, in the future?

It doesn't have the high level api. Sean Seefried actually implemented an hs-plugins-like interface to some bits of GHC, and I'd expect that hs-plugins 2 will just be a layer over ghc-api (or maybe part of ghc-api). Certainly the object loading and (ghci-based) evaluation could be moved from hs-plugins to ghc-api. The file merging operations, and possibly the native-code evaluation would require adding a layer over ghc-api. -- Don
Wow, that easy? Just eval "..."? Can't believe it.. Will have look at those examples.. Marc

For German readers, I put an example of a scripting task on that Wiki: http://www.wikiservice.at/dse/wiki.cgi?SpracheHaskell/Skripte
