usethis

Automatically manage Python tooling and configuration: linters, formatters, and more. A CLI for declaratively configuring your Python projects following best practices.

usethis is a command-line interface to automate the configuration of popular Python tools, workflows, and frameworks. You can use it to declaratively add, remove, and configure tools in an existing project, as well as set up a new project from scratch. It won't break your existing configuration, and ensures all tools work together smoothly.

usethis gives detailed messages about what it is doing (and what you need to do next).

  • Output beginning with ✔ represents a task which usethis has automated.
  • Output beginning with ☐ represents a task which you need to perform manually.
  • Output beginning with ℹ gives hints and tips.

Inspired by an R package of the same name, this package brings a similar experience to the Python ecosystem as a CLI tool.
