Attached is a module containing ByteString analogs of two functions from System.Process: readProcess and readProcessWithExitCode. I use these a

and would love to see them incorporated into a standard library, though I'm not sure which one.

Sorry, didn't know attachments were excluded. The two functions are available in the Unixutils library:

Some time ago I fixed some asynchronous exception bugs in those functions. Take a look at the current implementation:

You might want to incorporate these changes into your library.

It looks like this will have to wait for bytestring 0.10, which has NFData instances. I guess there are ways to hack this...

I have the process-extras library on Hackage which contains readProcessWithExitCode variants for ByteString and Text.

How about adding the same function for the lazy variants? John

I'd be happy to apply patches which add readProcess and make other improvements :-).

I made a pull request that fixes some asynchronous exception bugs and adds the System.Process.Text.Lazy module:

Awesome. I've merged the pull request. I'll release a new version shortly. Cheers, David

Does this depend on bytestring >= 0.10?

No. I just released a new version of process-extras with Bas van Dijk's improvements: http://hackage.haskell.org/package/process-extras-0.2.0 Cheers, David
