Title

Hatch: The only tool you need

Category

Packaging/tooling

Duration

30 minutes

Description

While other language ecosystems have a streamlined workflow that involves a single tool like Rust's Cargo and JavaScript's npm, maintaining Python projects has historically involved learning and using an ever-growing set of tools:

• packaging: distutils, setuptools, flit
• dependency management: pip, pip-tools, poetry
• Python management: pyenv, Homebrew, Windows store
• environments: virtualenv, tox, nox
• versioning: pbr, setuptools_scm, bump2version, versioneer
• builds: pip, build
• publishing: twine
• ...

This talk explains how Hatch can be that unified tool for Python.

Audience

Programmers at any level that wish to simplify their development experience.

Level

Any

Objectives
