pipettor - robust, easy to use Unix process pipelines
Project description
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.
- Documentation: https://pipettor.readthedocs.org.

- remove use of deprecated pipes module
0.5.0 (2020-12-25)

0.4.0 (2018-04-21)
- Allow passing through universial newline mode for PY2.
- Fix bug with not using specified log level.
