Dogmatic

An opinionated Python linter and formatter built on Ruff, with native rules for typed data boundaries, explicit dependency injection, async execution, pytest, and named constants.

uv tool install dogmatic
dogmatic check .
dogmatic format .

The Python package also supports python -m dogmatic. Dogmatic uses Ruff's configuration format, including [tool.ruff] in pyproject.toml, ruff.toml, and existing rule selectors and suppressions.

Dogmatic's release version is independent of its Ruff engine version. Ruff's required-version setting checks the engine version, currently 0.16.6.

Application-specific checks are opt-in preview rules. For example:

[tool.ruff.lint]
preview = true
extend-select = [
    "custom-prefer-dataclass",
    "custom-explicit-dependencies",
    "custom-no-service-locator",
    "custom-no-import-side-effects",
    "custom-no-bare-constants",
    "custom-no-thread-execution",
    "custom-no-test-mocking",
    "custom-require-pydantic-input",
]

Run dogmatic rule <rule-name> for a rule's behavior and examples.

Dogmatic includes Ruff, originally developed by Astral Software Inc., under the MIT license. The upstream project is available at astral-sh/ruff. Dogmatic is an independent distribution; its application-specific policies are not upstream Ruff rules.
