Get Started!¶

Ready to contribute? Here’s how to set up qddate for local development.

Fork the qddate repo on GitHub.
Clone your fork locally:
Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
```
$ mkvirtualenv qddate
$ cd qddate/
$ python setup.py develop
```
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:
```
$ pip install -r tests/requirements.txt # install test dependencies
$ flake8 qddate tests
$ nosetests
$ tox
```
To get flake8 and tox, just pip install them into your virtualenv. (Note that we use max-line-length = 100 for flake8, this is configured in setup.cfg file.)

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.
Check https://travis-ci.org/ivbeg/qddate/pull_requests and make sure that the tests pass for all supported Python versions.
Follow the core developers’ advice which aim to ensure code’s consistency regardless of variety of approaches used by many contributors.
In case you are unable to continue working on a PR, please leave a short comment to notify us. We will be pleased to make any changes required to get it done.

Guidelines for Adding New Languages¶

English and Russian are the primary languages of the qddate. All languages are pre-configured and manually added for speed optimization. DateParser has function __matchPrefix which filters patterns and minimizes date comparisons.

Languages added using DATE_DATA_TYPES_RAW constant in consts.py. It’s combined, inherited patterns and it’s manually configured and not so simplified yet.
