#1169 fixed Control.Monad.Cont documentation Andriy Andriy
Description

Currently this important monad module does not have any haddock comment.

Per Jeff Newbern's gracious permission included relevant information from his cool tutorial "All About Monads" http://www.nomaware.com/monads/, created a couple of examples.

#3441 worksforme readProcess ... (exit 11): failed simonmar Andriy
Description

When one haskell script (here Parent.hs) runs another script (Child.hs), it fails at some point with an error:

Parent.hs: readProcess: ./Child.hs "param1" "param2" ... "paramN" (exit 11): failed

Details:

I have a set of haskell scripts. Each script has following interpreter spec as the first line:

#!/usr/bin/env runghc

These scripts manage some Java building process. Child.hs is long-running. It can run for a few hours. It builds a Java application, runs tests on it. About once a week the parent script fails with the error above. I use the script about 2-5 times a day.

My system is Ubuntu 8.04 (Hardy Heron). I installed GHC 6.10.3 locally, I also have GHC 6.8.2 installed from the Ubuntu repositories.

Besides the problem itself, it is not clear what "exit 11" means.

#1340 fixed Hpc Documentation AndyGill AndyGill
Description

The -fhpc flag needs documentation in the GHC manual, and perhaps some small examples. Hpc itself needs better documentation, linked from the GHC documentation.
