PBR is a nice little add-on to simplify the setup and the deplyoment of your packages.

PBR stands for Python Build Reasonableness

and it is

A library for managing setuptools packaging needs in a consistent manner.

in their own words.

Installation

pip install pbr

setup.py

The first thing we can optimize is the structure of the setup.py file:

from setuptools import setup

setup(
    setup_requires=['pbr'],
    pbr=True
)

pyproject.toml

We need to add a pyproject.toml with the following content:

[build-system]
requires = ["pbr>=5.7.0", "setuptools>=36.6.0", "wheel"]
build-backend = "pbr.build"

setup.cfg

We also add a setup.cfg file which will contain the package metadata:

[metadata]
name = easy_pattern
author = Joern Boegeholz
author-email = boegeholz.joern@gmail.com
summary = A Pseudo-DSL for Python RegEx
description-file = README.md
home-page = https://github.com/jboegeholz/easypattern
license = MIT
classifier =
    Development Status :: 4 - Beta
    Intended Audience :: Developers
    Intended Audience :: Information Technology
    License :: OSI Approved :: MIT License
    Operating System :: OS Independent
    Programming Language :: Python
keywords =
    tutorial

[files]
packages =
    easy_pattern

classifier is a list of “trove classifiers”

Build a release

Tag the current version:

git tag -am "Version 0.3.0" 0.3.0

build the distribution

python setup.py sdist

under dist you will now find the release easy_pattern-0.3.0.tar.gz

Conclusion

Pros

• Automatically generates version from git tag
• Creates changelog

Cons

• YAD – yet another dependency & YACF – yet another config file
