flake8 for code in rst files and docstrings
Project description
flake8-rst module
Allows run flake8 on code snippets in docstrings or RST files.
Idea
idea proposed by Mike Bayer on https://github.com/zzzeek/sqlalchemy/pull/362
That said, if there was some alternate form of "doctest" that could simply test a code example both for Python syntax, pep8 compliance (which would be AWESOME) as well as symbol consistency, that would be helpful. The tool could be configured with common imports and symbols significant to SQLAlchemy examples and be helpful as a basic sanity check for code examples. As it is, when writing new documentation I have to organize and run the code in a separate .py file to make sure it does the right thing. So this is a problem, just my experience with doctest in writing the tutorials has shown me what it's good at and where it's likely getting in the way.
Realization inspired by https://github.com/asottile/blacken-docs
Usage
You can install tool from pip pip install flake8-rst
.
Tool search sourcecode
and code-block
blocks, crop and run flake8 on it:
.. sourcecode:: python
class Example(Base):
pass
or
.. code-block:: python
class Example(Base):
pass
Supporting all flake8 arguments and flags except jobs (temporary), with additional one:
flake8-rst --bootstrap "import test"
flake8-rst bootstraps code snippets with this code, useful for fix import errors.
Load configuration from [flake8-rst]
ini sections, like flake8.
