Report bugs at

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

daops could always use more documentation, whether as part of the official daops 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

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 daops for local development.

  1. Fork the daops repo on GitHub.

  2. Clone your fork locally:

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

    # For virtualenv environments:
    $ mkvirtualenv daops
    # For Anaconda/Miniconda environments:
    $ conda create -n daops python=3.6
    $ cd daops/
    $ pip install -e .
  4. Create a branch for local development:

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

    Now you can make your changes locally!

  5. When you’re done making changes, check that you verify your changes with black and run the tests, including testing other Python versions with tox:

    # For virtualenv environments:
    $ pip install black pytest tox
    # For Anaconda/Miniconda environments:
    $ conda install -c conda-forge black pytest tox
    $ black daops tests
    $ python test
    $ tox
  6. Before committing your changes, we ask that you install pre-commit in your virtualenv. Pre-commit runs git hooks that ensure that your code resembles that of the project and catches and corrects any small errors or inconsistencies when you git commit:

    # For virtualenv environments:
    $ pip install pre-commit
    # For Anaconda/Miniconda environments:
    $ conda install -c conda-forge pre_commit
    $ pre-commit install
  7. Commit your changes and push your branch to GitHub:

    $ git add *
    $ git commit -m "Your detailed description of your changes."
    # `pre-commit` will run checks at this point:
    # if no errors are found, changes will be committed.
    # if errors are found, modifications will be mades. Simply `git commit` again.
    $ git push origin name-of-your-bugfix-or-feature
  8. Submit a pull request through the GitHub website.


daops uses the loguru library as its primary logging engine. In order to integrate this kind of logging in processes, we can use their logger:

The mechanism for enabling log reporting in scripts/notebooks using loguru is as follows:

For convenience, a preset logger configuration can be enabled via daops.enable_logging().

Pull Request Guidelines

Before you submit a pull request, please follow these guidelines:

  1. Open an issue on our GitHub repository with your issue that you’d like to fix or feature that you’d like to implement.

  2. Perform the changes, commit and push them either to new a branch within roocs/daops or to your personal fork of daops.


Try to keep your contributions within the scope of the issue that you are addressing. While it might be tempting to fix other aspects of the library as it comes up, it’s better to simply to flag the problems in case others are already working on it.

Consider adding a “# TODO:” comment if the need arises.

  1. Pull requests should raise test coverage for the daops library. Code coverage is an indicator of how extensively tested the library is. If you are adding a new set of functions, they must be tested and coverage percentage should not significantly decrease.

  2. If the pull request adds functionality, your functions should include docstring explanations. So long as the docstrings are syntactically correct, sphinx-autodoc will be able to automatically parse the information. Please ensure that the docstrings adhere to one of the following standards:

  3. The pull request should work for Python 3.6, 3.7 and 3.8 as well as raise test coverage. Pull requests are also checked for documentation build status and for PEP8 compliance.

    The build statuses and build errors for pull requests can be found at:


PEP8 and Black is strongly enforced. Ensure that your changes pass Flake8 and Black tests prior to pushing your final commits to your branch. Code formatting errors are treated as build errors and will block your pull request from being accepted.
