You can contribute in many ways:

Types of Contributions¶

Report Bugs¶

Report bugs at https://github.com/AdRoll/python-hll/issues.

If you are reporting a bug, please include:

Your operating system name and version.
Any details about your local setup that might be helpful in troubleshooting.
Detailed steps to reproduce the bug.

Fix Bugs¶

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features¶

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation¶

python-hll could always use more documentation, whether as part of the official python-hll docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback¶

The best way to send feedback is to file an issue at https://github.com/AdRoll/python-hll/issues.

If you are proposing a feature:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!¶

Ready to contribute? Here’s how to set up python-hll for local development.

Fork the python-hll repo on GitHub.

Clone your fork locally:

$ git clone git@github.com:your_name_here/python-hll.git

Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
```
$ cd python-hll/
$ mkvirtualenv python_hll
$ python setup.py develop
$ pip install -r requirements_dev.txt
```
Create a branch for local development:
```
$ git checkout -b name-of-your-bugfix-or-feature
```
Now you can make your changes locally.
When you’re done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:
```
$ make lint
$ make test-fast
```
To run one test file or one test:
```
$ py.test --capture=no tests/test_sparse_hll.py
$ py.test --capture=no tests/test_sparse_hll.py::test_add
```
To run slow tests:
```
$ make test
```

Commit your changes and push your branch to GitHub:

$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

Submit a pull request through the GitHub website.

Pull Request Guidelines¶

Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.
The pull request should work for Python 2.7, 3.4, 3.5 and 3.6, and for PyPy. Make sure that the tests pass for all supported Python versions.

Deploying¶

A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in HISTORY.rst). Then run:

$ # Run bumpversion patch, or bumpversion minor, or bumpversion major.
$ # This will tag the code and increment/commit new version numbers.
$ bumpversion patch
$ git push
$ git push --tags
$ make release  # use your pypi credentials
$ # Log in to https://python-hll.readthedocs.io/ and publish the latest docs
