Project description
pypi-parker lets you easily park package names on PyPI to protect users of your packages from typosquatting.
Typosquatting is a problem: in general, but also on PyPI. There are efforts being taken by pypa to protect core library names, but this does not (and really cannot and probably should not attempt to) help individual package owners. For example, reqeusts rather than requests, or crytpography rather than cryptography. Because of the self-serve nature of PyPI, individual package owners are left to their own devices to protect their users. This is not inherently a problem: in my opinion this is a reasonable balance to keep the barrier to entry for publishing PyPI package low. However, tooling should exist to make it easy for package owners to protect their users. That is what pypi-parker sets out to do.
Objectives
Self-serve is a good thing. Let’s not try and get rid of that. Work with it instead.
Package owners should be able to easily protect users of their packages from malicious typosquatting.
It should be easy for package owners to introduce pypi-parker into their existing package builds.
Parked packages should:
fail fast and not do anything else
be self documenting, both in metadata and in source
contain functionally complete setup.py files to allow whitelisted external validators to work
The readme_renderer validator is run on each generated package before building.
What does it do?
pypi-parker provides a custom distutils command park that interprets a provided config file to generate empty Python package source distributables. These packages will always throw an ImportError when someone tries to install them. You can customize the ImportError message to help guide users to the correct package.
Using the Config File
pypi-parker uses a configparser config file to determine what packages to generate and what metadata to include with each.
There are two special sections: names and DEFAULT.
DEFAULT : Values in DEFAULT are used if that key is not present in a package-specific section.
names : Keys in names are interpretted as package names that should all use only the values in DEFAULT.
Unless otherwise indicated, all key/value pairs loaded for each package are loaded directly into the setup call for that generated package.
Special Packages
If you want to specify custom values for specific packages, you can add additional sections for those packages. For any sections found aside from DEFAULT and names, the section name is used as the package name.
Special Section Keys
description_keys : This line-delimited value is used with str.format to build the final description value.
classifiers : If multiple lines are provided for this value, and each line will be treated as a separate entry.
description :
This value cannot contain multiple lines.
This value is also used for the ImportError message in the generated setup.py.
Default Values
config file name : park.cfg
classifiers : Development Status :: 7 - Inactive
description : parked using pypi-parker
long_description :
This package has been parked either for future use or to protect against typo misdirection. If you believe that it has been parked in error, please contact the package owner.

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-oma2zoy6-build/Ok, how do I use it?
Install pypi-parker wherever you will be running your builds.
pip install pypi-parker
Define the package names you want to target in your config file.
Call setup.py with the park command.
python setup.py park
If you want to use a custom config file, specify it with the park-config argument.
python setup.py park --park-config={filename}
Upload the resulting contents of dist to your package index of choice.
