chine 0.1.2

A Python linting tool

chine

Chine is a static architecture checker for Python. It parses your code with ast, reads declared architecture roles, and reports dependency violations without importing or executing your modules.

What chine checks

Declare a role at module level:

__architecture_role__ = "use_case"

Supported roles:

• use_case
• domain_policy (and domain)
• adapter

Current rules:

• ARCH001: use case modules must not import adapter modules
• ARCH002: domain/domain_policy modules must not import adapter modules
• ARCH003: domain/domain_policy modules must not import use case modules

Modules without __architecture_role__ are treated as untyped (Any) for architecture checks.

Installation

Install from PyPI:

pip install chine

Or with pipx:

pipx install chine

End-user usage

Show CLI help:

chine --help

Check the current directory:

chine check

Check a specific path:

chine check src/

Show version:

chine --version

When no violations are found, chine exits successfully. If violations are found, it prints each ARCH rule violation with file and line number and exits with a non-zero status.
