Installation¶

Requirements¶

Python 3.10 or later

Install from source¶

git clone https://github.com/duriantaco/ca9.git
cd ca9
pip install .

This installs the core library. The only required runtime dependency is packaging, which ca9 uses for PEP 440 version comparison.

Install with CLI support¶

The CLI requires click:

pip install ".[cli]"

Development install¶

pip install ".[dev]"
pre-commit install

Or use the Makefile:

make dev

This installs all development dependencies (pytest, ruff, tox, pre-commit, skylos) and sets up pre-commit hooks.
