Hi all,
I have created a library, pipes-cliff, for interacting with subprocesses using Pipes.
It aims to be simple and straightforward. It's not as powerful as process-streaming--for instance you cannot combine standard output and standard error into the same stream (at least, not without doing the work yourself.) It doesn't do ByteString to Text conversions. But the API is (hopefully) easier to understand and works for the simple use cases that I need.
See also this previous thread for discussions of the various issues involved with streaming to and from subprocesses.
Feedback and bug reports welcome. Thanks. --Omari
