Pipettor Overview

pipettor - robust, easy to use Python package for running Unix process pipelines

Features

• Creating process pipelines in Python is either complex (e.g. subprocess), or not robust (e.g. os.system()). This package 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.

• Popen-style File-like objects for reading or writing a pipeline.
