sourcery-rules-generator 0.2.0

Generate architecture rules for Python projects.

Sourcery Rules Generator

This is an experimental project. It might become a part of the Sourcery CLI.

Sourcery Rules Generator creates architecture rules for your project.

The generated rules can be used by Sourcery to review your project's architecture.

Currently, the project can create dependency rules.

Usage

You can create Sourcery rules based on a template with the command:

sourcery-rules <TEMPLATE-NAME> create

Supported templates:

• dependencies
• naming (coming soon)

For example:

sourcery-rules dependencies create

Create Dependencies Rules

With the dependencies template, you can create rules to check the dependencies:

• between the packages of your application
• to external packages.

Let's say your project has an architecture like this:

You can create rules to ensure:

• no other package imports api
• only api imports core
• only db import SQLAlchemy
• etc.

Run the command:

sourcery-rules dependencies create

You'll be prompted to provide:

• a package name
• the packages that are allowed to import the package above

The 2nd parameter is optional.
E.g. it makes sense to say that no other package should import the api or cli package of your project.

=>

2 rules will be generated:

• 1 for import statements
• 1 for from ... import statements

Using the Generated Rules

The generated rules can be used by Sourcery to review your project. If you copy the generated rules into your project's .sourcery.yaml, Sourcery will use them automatically.

All the generated rules have the tag architecture. Once you've copied them to your .sourcery.yaml, you can run them with:

sourcery review --enable architecture .
