conduit-extra-1.1.11: Batteries included conduit: adapters for common libraries.

Safe HaskellNone




A full tutorial for this module is available on FP School of Haskell:

Note that this is a very thin layer around the Data.Streaming.Process module. In particular, it:

  • Provides orphan instances for conduit
  • Provides some useful helper functions



sourceCmdWithConsumer :: MonadIO m => String -> Consumer ByteString m a -> m (ExitCode, a) Source

Like sourceProcessWithConsumer but providing the command to be run as a String.

Since 1.1.2

sourceProcessWithConsumer :: MonadIO m => CreateProcess -> Consumer ByteString m a -> m (ExitCode, a) Source

Given a CreateProcess, run the process, with its output being used as a Source to feed the provided Consumer. Once the process has completed, return a tuple of the ExitCode from the process and the output collected from the Consumer.

Since 1.1.2

withCheckedProcessCleanup :: (InputSource stdin, OutputSink stderr, OutputSink stdout, MonadIO m, MonadMask m) => CreateProcess -> (stdin -> stdout -> stderr -> m b) -> m b Source

Same as withCheckedProcess, but kills the child process in the case of an exception being thrown by the provided callback function.
