Abilian Development Tools (abilian-devtools or adt)

Abilian Development Tools (ADT) is a curated collection of Python development tools that includes formatters, testing frameworks, style checkers, type checkers, and supply chain audit tools. By adding abilian-devtools = '*' to your project's requirements.in or pyproject.toml, you can access over 40+ curated projects and plugins. Proper configuration and usage in your project is still required. Additionally, the package provides a command-line interface (CLI) called adt to help users get started with various development tasks such as running tests, security audits, and code formatting. ADT was developped at Abilian as a tool to help manage dozens of Python projects (open source or not). We hope it can be useful to others too.

What this is?

This is a curated, and opiniated, collection of best-of-breed Python development tools:

• Formatters (black, isort, docformatter)
• Testing frameworks (pytest and friends, nox)
• Style checkers (ruff, flake8 and friends)
• Type checkers (mypy, pyright)
• Supply chain audit (pip-audit, safety, reuse, vulture, deptry)
• And more.

Obviously, all the credit goes to the creators and maintainers of these wonderful projects. You have all our gratitude!

Usage

Instead of having to track all the 40+ projects and plugins we have curated, you just need to add abilian-devtools = '*' in your project's requirements.in or pyproject.toml.

You still need to properly configure and call them in your own projects.

For example configuration, see, for instance, https://github.com/abilian/nua (Makefile, pyproject.toml, setup.cfg, tasks.py, noxfile.py...).

CLI helper

As a bonus, we're providing a CLI called adt which can help you get started:

$ adt
adt (0.5.x)

Usage:
  adt <command> [options] [arguments]

Options:
  -V  Show version and exit
  -d  Enable debug mode
  -v  Increase verbosity

Available commands:
  all           Run everything (linters and tests).
  audit         Run security audit.
  bump-version  Bump version in pyproject.toml, commit & apply tag.
  check         Run checker/linters on specified files or directories.
  clean         Cleanup cruft.
  cruft         Run cruft audit.
  format        Format code in specified files or directories.
  help-make     Helper to generate the `make help` message.
  test          Run tests.

Why this?

We have created Abilian DevTools to help us maintain our own projects, and we thought it could be useful to others.

Here are some of the reasons why we have created this project:

• Streamlined Tool Collection: Abilian Devtools brings together a wide range of Python development tools in a single, curated package. This allows developers to focus on their work without spending time searching for and integrating individual tools.

• Consistency: By using a curated set of best-of-breed tools, our team can achieve a consistent level of code quality, style, and security across their projects.

• Simplified Dependency Management: Instead of managing individual dependencies for each tool, developers only need to add abilian-devtools to their project's requirements.in or pyproject.toml. This makes it easier to maintain and update dependencies over time.

• Easy-to-use CLI: The adt command-line utility simplifies common development tasks such as running tests, code formatting, and security audits. This can save time and effort, especially for those new to these tools.

• Up-to-date Toolset: Abilian Devtools aims to provide an up-to-date collection of tools, ensuring that developers have access to the latest features and improvements without having to manually track and update each tool.

Roadmap

Here are some ideas for future improvements:

• Support for additional tools: for instance, tools that deal with changelogs (via Conventional Commits), versioning, documentation...

• Monorepo support: Better support for monorepos.

• Customization: The curated nature of Abilian Devtools means that it comes with a predefined set of tools. Your project may require additional or alternative tools, or different settings. ADT could help managing (and updating) settings according to your own tastes and needs.

• Generating configuration and supporting files: Currently our projects are generated from a template by third-party tools (Cruft or Cookiecutter, using this template). ADT could help generating configuration files for the various tools (pyproject.toml, setup.cfg, noxfile.py, Makefile, tasks.py...).

• Updating configuration and supporting files: As tools and best practices evolves, and for long-running projects, configuration need to be adapted over time, which can become quite time-consuming, specially when you are working on many small projects (or monorepos). Tools like Cruft or Medikit) can help, but in our experience are too fragile. ADT could help with this.

• CI/CD: ADT could help with CI/CD integration.
