Get Started!

Ready to contribute? Here's how to set up `scrapy-redis` for local development.

Setup environment
~~~~~~~~~~~~~~~~~

1. Fork the `scrapy-redis` repo on GitHub.
2. Clone your fork locally::

       git clone git@github.com:your_name_here/scrapy-redis.git

3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development::

       pip install virtualenv==20.0.23
       virtualenv --python=/usr/bin/python3 ~/scrapy_redis
       source ~/scrapy_redis/bin/activate
       cd scrapy-redis/
       pip install -r requirements-install.txt
       pip install .

4. Create a branch for local development::

       git checkout -b name-of-your-bugfix-or-feature

   Now you can make your changes locally.

Setup testing environment
~~~~~~~~~~~~~~~~~~~~~~~~~

1. When you're done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox::

       pip install -r requirements-tests.txt
       flake8 src/ tests/
       python -m pytest --ignore=setup.py
       tox

2. Note that if the error of `No module named scrapy_redis` shows, please check the install `scrapy-redis` of your branch by::
   
       pip install .

3. Or change the import lines::

       from scrapy_redis import xxx # from this
       from src.scrapy_redis import xxx # to this

4. 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

5. Submit a pull request through the GitHub website.

Pull Request Guidelines
-----------------------

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

1. The pull request should include tests.
2. 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.
3. Make sure that the tests pass for all supported Python versions.

Tips
----

To run a subset of tests::

    pytest tests/test_scrapy_redis
