I was wondering what the state of the System.Process module described on

is?

I have tried to use the various POpen-like implementations out there, but _none_ of them works with the most current GHC. Is there any way to communicate with external programs at the moment? Posix-only would be suffice at the moment.

I posted code with POSIX & Windows versions recently: http://www.haskell.org//pipermail/libraries/2004-June/002265.html It's nearly finished, I hope to get it into GHC 6.4. You need to compile with -threaded in order to get a non-blocking waitForProcess. Cheers, Simon
