Writing an Extension for Flake8
|
||||
===============================
|
||||
|
||||
Since Flake8 is now adding support for extensions, we require ``setuptools``
|
||||
so we can manage extensions through entry points. If you are making an
|
||||
existing tool compatible with Flake8 but do not already require
|
||||
``setuptools``, you should probably add it to your list of requirements. Next,
|
||||
you'll need to edit your ``setup.py`` file so that upon installation, your
|
||||
extension is registered. If you define a class called ``PackageEntryClass``

We used ``P10`` here, but in reality, you should check to prevent as much
|
||||
future overlap as possible with other extensions. ``W`` and ``E`` followed by
|
||||
three digits should be considered entirely reserved for pep8. ``F`` should be
|
||||
considered reserved for Pyflakes and ``C`` for McCabe. Also, in anticipation
|
||||
of possible pylint integration, ``W`` and ``E`` followed by four digits should
|
||||
be considered reserved. We have no way of checking for those though, so while
|
||||
we ask you not use them, we can not (currently) prevent you from doing so.
|
||||
|
||||
A Real Example: McCabe
|
||||
If you intend to publish your extension, choose a unique code prefix
|
||||
following the convention for :ref:`error codes <error-codes>`.
|
||||
In addition, you can open a request in the `issue tracker
|
||||
<https://bitbucket.org/tarek/flake8/issues>`_ to register the prefix in the
|
||||
documentation.

.. TODO: describe the API required for the 3 kind of extensions:
|
||||
* physical line checkers
|
||||
* logical line checkers
|

* AST checkers
