Hi all, I'm using ghc/ghci 6.8.2 and looking at the System.Process module. Hoogle lists functions like readProcess and readProcessWithExitCode but they don't seem to exist. Is 6.8.2 too early?

It seems the answer is yes, 6.8.2 is too early. Now trying to create reimplement readProcess in terms of runInteractiveProcess.

Why do this extra work instead of simply upgrading to 6.8.3?

Mainly because 6.8.2 is installed on my Ubuntu system using a pre-compiled package (including a bunch of pre-compiled libraries). I much prefer to use the the native packaging system because most of the time it works so much better than anything else. Also, the "extra work" became a few minor tweaks to this code: http://www.cse.unsw.edu.au/~dons/code/newpopen/System/Process/Run.hs Cheers, Erik -- ----------------------------------------------------------------- Erik de Castro Lopo ----------------------------------------------------------------- "Using Java as a general purpose application development language is like going big game hunting armed with Nerf weapons." -- Author Unknown

So nag the Ubuntu ghc maintainer about being several versions behind. Or if
they're actually not several versions behind, you're just using an old
version of ubuntu, install a copy of ghc from a newer version of ubuntu.

I'm running the current latest release of Ubuntu and using the latest ghc they offer. The Ubuntu people just grab their version from Debian. I'm actually tracking the Debian Haskell mailing list and just in the last week there was an announcement of ghc-6.10.1 going into the experimental repository. Then they need to compile all the libraries with the new compiler. I'm thinking of grabbing the debian source package from Debian experimental and building it on Ubuntu.
