oxyba 0.31.1

my wrapper functions and classes for python

oxyba -- my wrapper functions and classes for python

Don't use this package.

I decided to apply the micro packaging approach instead of dumping everything into this package.

The oxyba package contains my wrapper functions and classes.

There is no particular purpose nor structure within this package. New wrapper functions and classes are just added to main package folder.

I advise against using any of this code in production.
Just don't. Feel free to copy code and adjust it to your own needs.

Installation

Check the source code at https://github.com/ulf1/oxyba

pip install oxyba

Load the package

I am going to use the ox shortcut

import oxyba as ox

Versioning

After v0.1.11 the versioning rules changed. A version X.Y.Z will have the following meaning.

• X: Major changes for the package
• Y: New function, class, module was added
• Z: Bugfixes, minor changes

Notes to myself

1. Update setup.py (version, requirements)
2. Update CHANGES.txt (what's added, changed, removed?)
3. Run: python setup.py sdist upload -r pypi

• use flake8 --ignore=F401
• use autopep8 --in-place oxyba/*.py
