Readme for process-conduit-

process-conduit: Conduit for processes


This package provides conduit for processes. Also this provides quasi-quoters for process using it.


$ cabal update
$ cabal install process-conduit


Haddock documents are here:

Quasi Quoters

process-conduit has three quasi-quoters, cmd, scmd and ccmd.

The result type of cmd is Lazy ByteString, but execution will perform strictly.

The result type of scmd and ccmd are GSource m ByteString and GConduit ByteString m ByteString respectively.

If a command is failed, an exception is thrown.

Commands are executed in run-time, not compile-time.
