pipettor 1.0.0

Description:

pipettor 1.0.0

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.

History
1.0.0 (2023-06-29)

Don't use a process group; as it caused signals to not get propagated. Processes are explicitly waited for by pid, so this will not consume the exit of other process not create by this module.

0.8.0 (2023-02-05)

make most optional arguments require keyword form to help prevent errors, especially if open() options are assumed
added more functions to make Popen objects file-like objects

0.7.0 (2023-01-06)

don't fail if invalid UTF-8 characters are written to capture stderr

0.6.0 (2022-11-16)

remove use of deprecated pipes module

0.5.0 (2020-12-25)

Removed Python-2 support.
Switch to using subprocess as a base rather interface directly
with Unix system calls. This lets subprocess deal with
various issues dealing with the Python interpreter environment.

0.4.0 (2018-04-21)

Allow passing through universial newline mode for PY2.
Fix bug with not using specified log level.

0.3.0 (2018-02-25)

added open-stying buffering, encoding, and errors options
source cleanup

0.2.0 (2017-09-19)

Simplified and log of info and errors levels by removing logLevel options.
Improvements to documentation.

0.1.3 (2017-06-13)

Documentation fixes

0.1.2 (2017-06-11)

First public release on PyPI.
