Awesome pyproject.toml Awesome Link Checker GH Action Status


pyproject.toml is a new configuration file defined in PEP 518. It is design to store build system requirements, but it can also store any tool configuration for your Python project, possibly replacing the need for setup.cfg or other tool-specific files.

We think pyproject.toml is pretty awesome, so this awesome list contains projects already using it, or discussing its inclusion.

Do you know of any other project not included here? Please submit a PR!

  • Tox - A generic virtualenv manager to run test in different environments.

Code Formatting

  • autopep8 - A tool that automatically formats Python code to conform to the PEP 8 style guide.
  • Black - The uncompromising Python code formatter.
  • isort - A Python utility / library to sort imports alphabetically, and automatically separated into sections.

Code Analysis
