pipettor 0.4.0

Creating process pipelines in Python is either complex (e.g. subprocess), or not robust (e.g. os.system()). This package provides aims to address these shortcomings.

Command pipelines are simply specified as a sequence of commands, with each command represented as a sequence of arguments.

Failure of any process in the pipeline results in an exception, with stderr included in the exception.

Pipeline stdin/stdout/stderr can be passed through from parent process, redirected to a file, or read/written by the parent process.

Asynchronous reading and writing to and from the pipeline maybe done without risk of deadlock.

Pipeline can run asynchronously or block until completion.

File-like objects for reading or writing a pipeline.
