Documentation

flake8-import-order-spoqa

This extends flake8-import-order to implement Spoqa's import order convention. It basically follows PEP 8 with our some additional rules:

  • Standard libraries shouldn't be imported using from ... import ... statement. It's because standard libraries tend to use general terms like open. We instead use always qualified imports to eliminate name pollution:

    import sys  # Yes
    
    from sys import version_info  # No

    However, there are few exceptions like typing module. They can be imported in both ways:

    import typing
    from typing import Optional  # `from ... import ...` must be latter
  • All other than standard libraries should be imported using from ... import ... statement:

    from flask import Flask  # Yes
    
    import flask  # No
  • Deeper relative imports should go former. This rule makes consistent even when relative imports are rewritten as absolute imports.

    from ..deeper import former
    from ...deepest import later
  • Imported names are splited to three categories: CONSTANT_NAME, ClassName, and normal_names, and follow that order:

    from something import CONST_A, CONST_B, ClassA, ClassB, any_func, any_var

Usage

Install the flake8-import-order-spoqa using pip, and then specify --import-order-style=spoqa option. Or you can specify it on the config file as well:

[flake8]
import-order-style = spoqa

Because runtime extensible styles is introduced from flake-import-order 0.12, you need to install flake-import-order 0.12 or later.

Changelog

Version 1.5.1

To be released.

Version 1.5.0

Released on August 31, 2018.

  • The dataclasses module, like typing, now can be imported without a qualifier (e.g., from dataclasses import ...).

Version 1.4.1

Released on August 6, 2018.

  • Python 3.7 can be supported by updating flake8-import-order to 0.18. See its changelog to know more about updates.

Version 1.4.0

Released on May 22, 2018.

  • Python 3.3 became no more supported.

Version 1.3.0

Released on February 12, 2018.

  • Older versions than flake8-import-order 0.17 are now unsupported. (Under the hood, since flake8-import-order 0.17 refactored their internals so that constants like IMPORT_3RD_PARTY, IMPORT_APP, IMPORT_APP_PACKAGE, IMPORT_APP_RELATIVE, and IMPORT_STDLIB are evolved to ImportType enum type, flake8-import-order-spoqa also became to follow that.) [#3]

Version 1.2.0

Released on November 27, 2017.

  • Older versions than flake8-import-order 0.16 are now unsupported. (Under the hood, since flake8-import-order 0.16 refactored their internals so that no more Style.check() method and Style.imports property exist, flake8-import-order-spoqa also became to follow that.)

Version 1.1.0

Released on October 31, 2017.

  • Older versions than flake8-import-order 0.14.2 are now unsupported.
