pip_missing_reqs 1.1.2

pip-missing-reqs
================

It happens: you start using a module in your project and it works and you
don't realise that it's only being included in your `virtualenv`_ because
it's a dependency of a package you're using. This tool finds those modules so
you can include them in the `requirements.txt`_ for the project.

.. _`virtualenv`: https://virtualenv.pypa.io/en/latest/
.. _`requirements.txt`: https://pip.pypa.io/en/latest/user_guide.html#requirements-files

Assuming your project follows a layout like the suggested `sample project`_::

setup.py
setup.cfg
requirements.txt
sample/__init__.py
sample/sample.py
sample/tests/test_sample.py

.. _`sample project`: https://packaging.python.org/en/latest/tutorial.html#creating-your-own-project

Basic usage, running in your project directory::

<activate virtualenv for your project>
pip-missing-reqs --ignore-files=sample/tests/* sample

This will find all imports in the code in "sample" and check that the
packages those modules belong to are in the requirements.txt file.


Sample tox.ini configuration
----------------------------

To make your life easier, copy something like this into your tox.ini::

[pip-missing-reqs]
deps=-rrequirements.txt
commands=pip-missing-reqs --ignore-files=sample/tests/* sample


Excluding test files (or others) from this check
------------------------------------------------

Your test files will sometimes be present in the same directory as your
application source ("sample" in the above examples). The requirements for
those tests generally should not be in the requirements.txt file, and you
don't want this tool to generate false hits for those.

You may exclude those test files from your check using the --ignore-files
option.


Excluding modules from the check
--------------------------------

If your project has modules which are conditionally imported, or requirements
which are conditionally included, you may exclude certain modules from the
check by name (or glob pattern) using --ignore-mods::

# ignore the module spam
pip-missing-reqs --ignore-mods=spam sample
# ignore the whole package spam as well
pip-missing-reqs --ignore-mods=spam --ignore-mods=spam.* sample
