postal-address 0.9.0

Motivation

« What ties us to territory is tax. » – Kevin Deldycke, 2014-11-07

The reason above is why we need fine-grained and meticulous territory management and normalization. This project aims to solve this problem once for all.

Don’t get me wrong, this work is a huge undertaking. Postal address parsing, normalization and rendering is hard. Much harder than you think. Please read the famous Falsehoods programmers believe about addresses pamphlet.

This library is still in its early stages, but is good enough to implement the new European Directives on VAT, which requires all e-commerce shops to guess the locality of their EU customers depending on their billing address.

Install

This package is available on PyPi, so you can install the latest stable release and its dependencies with a simple pip call:

$ pip install postal-address

Development

Check out latest development branch:

$ git clone git@github.com:scaleway/postal-address.git
$ cd ./postal-address
$ python ./setup.py develop

Run unit-tests:

$ python ./setup.py nosetests

Run PEP8 and Pylint code style checks:

$ pip install pep8 pylint
$ pep8 postal-address
$ pylint --rcfile=setup.cfg postal-address

Stability policy

Here is a bunch of rules we’re trying to follow regarding stability:

• Patch releases (0.x.n → 0.x.(n+1) upgrades) are bug-fix only. These releases must not break anything and keeps backward-compatibility with 0.x.* and 0.(x-1).* series.

• Minor releases (0.n.* → 0.(n+1).0 upgrades) includes any non-bugfix changes. These releases must be backward-compatible with any 0.n.* version but are allowed to drop compatibility with the 0.(n-1).* series and below.

• Major releases (n.*.* → (n+1).0.0 upgrades) are not planned yet: we’re still in beta and the final feature set of the 1.0.0 release is not decided yet.

Release process

Start from the develop branch:

$ git clone git@github.com:scaleway/postal-address.git
$ git checkout develop

Revision should already be set to the next version, so we just need to set the released date in the changelog:

$ vi ./CHANGES.rst

Create a release commit, tag it and merge it back to master branch:

$ git add ./postal_address/__init__.py ./CHANGES.rst
$ git commit -m "Release vX.Y.Z"
$ git tag "vX.Y.Z"
$ git push
$ git push --tags
$ git checkout master
$ git pull
$ git merge "vX.Y.Z"
$ git push

Push packaging to the test cheeseshop:

$ pip install wheel
$ python ./setup.py register -r testpypi
$ python ./setup.py clean
$ rm -rf ./build ./dist
$ python ./setup.py sdist bdist_egg bdist_wheel upload -r testpypi

Publish packaging to PyPi:

$ python ./setup.py register -r pypi
$ python ./setup.py clean
$ rm -rf ./build ./dist
$ python ./setup.py sdist bdist_egg bdist_wheel upload -r pypi

Bump revision back to its development state:

$ pip install bumpversion
$ git checkout develop
$ bumpversion --verbose patch
$ git add ./postal_address/__init__.py ./CHANGES.rst
$ git commit -m "Post release version bump."
$ git push

Now if the next revision is no longer bug-fix only:

$ bumpversion --verbose minor
$ git add ./postal_address/__init__.py ./CHANGES.rst
$ git commit -m "Next release no longer bug-fix only. Bump revision."
$ git push
