pd-code-sanity

Validate the structural invariants of planar-diagram codes.

Installation

pip install pd-code-sanity

Quick start

from pd_code_sanity import sanity; the function returns a boolean.

PD codes are lists of four-entry crossings. Each arc label must occur exactly twice. Functions validate their inputs and do not mutate caller-owned PD-code lists unless explicitly documented.

Development

Use Python 3.10 or newer for Python packages. Build distributions with poetry build. Run the package's tests or examples before publishing. C++ projects require a modern standards-compliant compiler.
