Thank you for considering improving Loguru, any contribution is much welcome!

Asking questions

If you have any question about Loguru, if you are seeking for help, or if you would like to suggest a new feature, you are encouraged to open a new issue so we can discuss it. Bringing new ideas and pointing out elements needing clarification allows to make this library always better!

Reporting a bug

If you encountered an unexpected behavior using Loguru, please open a new issue so we can fix it as soon as possible! Be as specific as possible in the description of your problem so we can fix it as quickly as possible.

An ideal bug report includes:

  • The Python version you are using
  • The Loguru version you are using (you can find it with print(loguru.__version__))
  • Your operating system name and version
  • Your development environment and local setup (IDE, Terminal, project context, anything that could be useful)
  • Some minimal reproducable example

Implementing changes

If you are willing to enhance Loguru by implementing non-trivial changes, please open a new issue first to keep a reference about why such modifications are made (and potentialy avoid unneeded work). Then, the workflow would look as follow:

  1. Fork the Loguru project from Github

  2. Clone the repository locally:

    $ git clone
    $ cd loguru
  3. Activate your virtual environment:

    $ python -m virtualenv env
    $ source env/bin/activate
  4. Create a new branch from master:

    $ git checkout master
    $ git branch fix_bug
    $ git checkout fix_bug
  5. Install Loguru in development mode:

    $ pip install -e .[dev]
  6. Implement the modifications wished. During the process of development, honor PEP 8 as much as possible.

  7. Add unit tests (don’t hesitate to be exhaustive!) and ensure none are failing using:

    $ pytest tests
  8. Remember to update documentation if required

  9. Update the changelog.rst file with what you improved

  10. add and commit your changes, rebase your branch on master, push your local project:

    $ git add .
    $ git commit -m 'Add succinct explanation of what changed'
    $ git rebase master
    $ git push origin fix_bug
  11. Finally open a pull request before getting it merged!
