Flake8 meet isort

=================

Use `isort`_ to check if the imports on your python files are sorted the way you expect.



Add an ``.isort.cfg`` to define how you want your imports sorted and run flake8 as you usually do.



See `isort documentation`_ for ``.isort.cfg`` available options.



Install

-------

Install with pip::



    $ pip install flake8-isort



Install with conda::



    $ conda install -c conda-forge flake8-isort



Configuration

-------------

If using the `select` `option from flake8`_ be sure to enable the `I` category as well, see below for the specific error codes reported by `flake8-isort`.



See ``flake8 --help`` for available flake8-isort options.



Error codes

-----------

+------------+-----------------------------------------------------------+

| Error code | Description                                               |

+============+===========================================================+

| I002       | no configuration found (.isort.cfg or [isort] in configs) |

+------------+-----------------------------------------------------------+

| I003       | isort expected 1 blank line in imports, found 0           |

+------------+-----------------------------------------------------------+

+------------+-----------------------------------------------------------+



Requirements

------------

- Python 3.8, 3.9, 3.10, 3.11 and pypy3

- flake8

- isort



Relation to flake8-import-order

-------------------------------



As an alternative to this flake8 plugin, there's `flake8-import-order`_ that could be worth checking out. In contrast to this plugin that defers all logic to isort, the flake8-import-order comes bundled with it's own logic.



flake8-import-order comes with a few predefined set of styles meanwhile this plugin can be customized a bit more. But the biggest difference could lie in that flake8-isort actually has the corresponding sorting engine isort that can sort the import orders of your existing python files. Meanwhile flake8-import-order has no such corresponding tool, hence big existing projects who want to adopt either would get a more automized experience choosing flake8-isort.
