cookiecutter-pypackage-minimal
|
|
==============================
|
|
|
|
An opinionated, minimal cookiecutter template for Python packages, and some guidelines for Python packaging.
|
|
|
|
Usage
|
|
-----
|
|
|
|
::
|
|
|
|
pip install cookiecutter
|
|
git clone https://github.com/borntyping/cookiecutter-pypackage-minimal.git
|
|
cookiecutter cookiecutter-pypackage-minimal/
|
|
|
|
You should then change the classifiers in `{{ package_name }}/setup.py` - it is assumed that the project will run on the latest versions of Python 2 and 3, so you should remove any classifiers that do not apply. The full list of PyPI classifiers can be found [here](https://pypi.python.org/pypi?:action=list_classifiers).
|
|
|
|
Fill out the README, and - if necessary - add a license to the project.

Explanation
|
|
-----------
|
|
|
|
The decisions `cookiecutter-pypackage-minimal` makes should all be explained here.
|
|
|
|
### README
|
|
|
|
* **README should use reStructuredText format**
|
|
This is the format used by most Python tools, and is expected by setuptools
|
|
* **As few README files as possible**
|
|
Additional README files (AUTHORS, CHANGELOG, etc) should be left to the user to create when necessary.
|
|
|
|
### `setup.py`
|
|
|
|
* **Use setuptools**
|
|
It's the standard packaging library for Python. `distribute` has merged back into `setuptools`, and `distutils` is less capable.
|
|
* **setup.py should not import anything from the package**
|
|
When installing from source, the user may not have the packages dependencies installed, and importing the package is likely to raise an `ImportError`.
|
|
* **setup.py should be the canonical source of package dependencies**
|
|
There is no reason to duplicate dependency specifiers (e.g. also using `requirements.txt`)
|
|
See the testing section below for testing dependencies.
|
|
|
|
### Testing
|
|
|
|
* **Use [Tox](http://testrun.org/tox/latest/) to manage test environments**
|
|
Tox provides isolation, runs tests across multiple Python versions, and ensures the package can be installed.
|
|
* **Uses [pytest](http://pytest.org/latest/) as the default test runner**
|
|
This can be changed easily, though pytest is a easier, more powerful test library and runner than the standard library's unittest.
|
|
* **Define testing dependencies in `tox.ini`**
|
|
Avoid duplicating dependency definitions, and use `tox.ini` as the canonical description of how the unittests should be run.
