Introduction
------------

pkutils is a Python library_ that simplifies python module packaging. It is
intended to be used in your package's ``setup.py`` file.

With pkutils, you can

- Parse requirements files
- Determine your project's development status
- Read text files
- and much more...

Requirements
------------

pkutils has been tested and is known to work on Python 2.7, 3.5, and 3.6;
PyPy2.7; and PyPy3.5.

Motivation
----------

Python has a great packaging system, but to actually create and publish a
package requires a lot of work to do well. I designed pkutils to provide
many useful packaging use-cases out of the box. For example, to automatically
include the contents of your ``requirements.txt`` file, simply add the following
to ``setup.py``:

.. code-block:: python

import pkutils

...

requirements = list(pkutils.parse_requirements('requirements.txt'))
dev_requirements = list(pkutils.parse_requirements('dev-requirements.txt'))

setup(
...
install_requires=requirements,
tests_require=dev_requirements,
...)

.. _library:

Usage
-----

pkutils is intended to be used directly as a Python library.

``my_package/__init__.py``

.. code-block:: python

__version__ = '0.5.4'

__author__ = 'Reuben Cummings'
__description__ = 'My super awesome great package'
__email__ = 'reubano@gmail.com'
__license__ = 'MIT'
__copyright__ = 'Copyright 2015 Reuben Cummings'

You can ``__title__`` explicitly in your Python file. If you leave
``__title__`` unset, pkutils will use:

* The parent directory for paths ending in ``__init__.py``.
* The filename before the extention for other paths
(e.g. ``my_package`` for ``my_package.py``).

``setup.py``

.. code-block:: python

import pkutils

try:
from setuptools import setup
except ImportError:
from distutils.core import setup

requirements = list(pkutils.parse_requirements('requirements.txt'))
dependencies = list(pkutils.parse_requirements('requirements.txt', True))
dev_requirements = list(pkutils.parse_requirements('dev-requirements.txt'))
readme = pkutils.read('README.rst')
module = pkutils.parse_module('my_package/__init__.py')
version = module.__version__
project = module.__title__
email = module.__email__
user = pkutils.get_user(email)

setup(
name=project,
version=version,
description=module.__description__,
long_description=readme,
author=module.__author__,
author_email=email,
install_requires=requirements,
tests_require=dev_requirements,
dependency_links=dependencies,
setup_requires=['pkutils'],
url=pkutils.get_url(project, user),
download_url=pkutils.get_dl_url(project, user, version),
classifiers=[
pkutils.get_license(module.__license__),
pkutils.get_status(version),
...
],
...
)

This is then converted into something like the following:

.. code-block:: python

...

setup(
name='my_package',
version='0.5.4',
description='My super awesome great package',
long_description='my_package: a super awesome great...',
author='Reuben Cummings',
author_email='reubano@gmail.com',
install_requires=['semver==2.2.1'],
tests_require=['semver==2.2.1', 'wheel==0.24.0', 'flake8==2.5.1', ...],
dependency_links=[],
setup_requires=['pkutils'],
url='https://github.com/reubano/pkutils',
download_url='https://github.com/reubano/pkutils/archive/v0.5.4.tar.gz',
classifiers=[
'License :: OSI Approved :: MIT License',
'Development Status :: 4 - Beta',
...
],
...
)

Installation
------------

(You are using a `virtualenv`_, right?) [#]_

At the command line, install pkutils using either ``pip`` (*recommended*)

.. code-block:: bash

pip install -u pkutils

or ``easy_install``

.. code-block:: bash

easy_install pkutils

Please see the `installation doc`_ for more details.

Design Principles
-----------------

- minimize external dependencies
- prefer functions over objects
- keep the API as simple as possible

Scripts
-------

pkutils comes with a built in task manager ``manage.py``

Setup
~~~~~

.. code-block:: bash

pip install -r dev-requirements.txt

Examples
~~~~~~~~

*View available commands*

.. code-block:: bash

manage

*Show help for a given command*

.. code-block:: bash

manage <command> -h

*Run python linter and nose tests*

.. code-block:: bash

manage lint
manage test

Or if ``make`` is more your speed...

.. code-block:: bash

make lint
make test

Contributing
------------

Please mimic the coding style/conventions used in this repo.
If you add new classes or functions, please add the appropriate doc blocks with
examples. Also, make sure the python linter and nose tests pass.

Please see the `contributing doc`_ for more details.
