atan

atan bootstraps Python environments into DCC applications. It builds a virtual environment that is compatible with a target host, installs packages into it, and wires that environment into the host's startup so the packages are importable from inside the application.

The first supported host is Autodesk Maya 2025+, with uv doing the environment and package work.

Why

Maya ships its own isolated Python interpreter with no pip and no easy way to add third-party packages. atan gives you a repeatable, per-project environment whose Python version matches Maya's, verifies packages are compatible, and links it into Maya through the standard module mechanism — no manual sys.path hacking and nothing to reinstall each Maya launch.

cd my-anim-tools     # your tool project
atan init --maya 2025   # declare the environment in pyproject.toml
atan sync               # create the env, editable-install your project
atan launch             # start Maya 2025 with your code importable

Environments can also be managed standalone (atan create / install / link / verify / launch) without a project.

Status

This release reserves the package name while atan is in early development — it contains no functional code yet. Until a real release lands here, install from the repository:

uv tool install git+https://github.com/redd76/atan
