This seems to work fine. Thanks. Couldn't find the source snippet in the hide sources online. I take it the source is from the ghc port you are working on right now? Are the sources available or do you need anybody to test? :) Thanks again.

ghc api / calling functions?
Dear all, Is there a way to use the ghc api to call functions directly instead of evaluating statements (more or less similar to hs-plugins)? So far, thanks to some info pages, I have been able to load sessions and make modules, however there seems to be little or no documentation on calling functions directly. Any info/pointers appreciated. Thanks. Kind regards, Maarten ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
