pylint module boundaries

a pylint plugin to enforce boundaries between modules in your project. similar to nx's enforce-module-boundaries eslint plugin

example

say you have three packages in your project - common, package1, and package2 - you can use the banned-imports rule to prevent common from importing anything from package1 or package2, thus avoiding issues such as circular dependencies.

Pylint can then be used to detect any violations of this rule:

see usage below for a config example

installing

poetry install pylint-module-boundaries

usage

`pyproject.toml` example

[tool.pylint.MASTER]
load-plugins = "pylint_module_boundaries"
banned-imports = '''
{
    "common(\\..*)?": ["package1(\\..*)?", "package2(\\..*)?"],
    "scripts(\\..*)?": ["package1(\\..*)?", "package2(\\..*)?"]
}
'''
banned-imports-check-usages = true

options

option	type	description	default
`banned-imports`	`string`	a JSON object pairing regexes matching modules to arrays of regexes matching modules that they are not allowed to import from. due to the limitations in config types allowed by pylint, this has to be a JSON object represented as a string. note that these regexes must be a full match, so to match any submodules you should append `(\\..*)?` to the regex (double `\` required because it's JSON). yes, i know this option is quite annoying to use but its purpose is to be as flexible as possible. i plan to add an easier to use option in the future that covers most basic use cases. see this issue	`{}`
`banned-imports-check-usages`	`boolean`	whether usages of the imports should be checked as well as the imports themselves. works on imports of entire modules but can potentially cause false positives depending on your use case	`true`
