Please follow these coding conventions when writing code for inclusion in
Scrapy:
-* Unless otherwise specified, follow :pep:`8`.
-
-* It's OK to use lines longer than 79 chars if it improves the code
- readability.
+* We use `black `_ for code formatting.
+ There is a hook in the pre-commit config
+ that will automatically format your code before every commit. You can also
+ run black manually with ``tox -e black``.
* Don't put your name in the code you contribute; git provides enough
metadata to identify author of the code.

Pre-commit
==========
-Pre-commit is a tool that allows developers to specify a set of checks to be run
-automatically every time they make a commit. This can include code style checks,
-linting, and automated tests.
-The checks are defined in a configuration file called .pre-commit-config.yaml.
+We use `pre-commit`_ to automatically address simple code issues before every
+commit.
-By using pre-commit, developers can ensure that their code adheres to a consistent
-style and passes certain tests before they make a commit.
-This can help catch errors early in the development process and prevent them
-from being pushed to the main branch.
+Before you start writing a patch:
+#. `Install pre-commit `_.
+#. On the root of your local clone of the Scrapy repository, run the following command:
+ .. code-block:: bash
+
+ pre-commit install
-To use pre-commit, developers first need to install it on their local machine.
-Once it is installed, they can specify the checks they want to run in the .pre-commit-config.yaml file.
-After that, pre-commit will run automatically every time they make a commit.
+Now our pre-commit hooks will run every time you create a Git commit. Upon
+finding issues, pre-commit hooks aborts your commit, and they either fix
+the corresponding issues automatically or only report them to you. If they fix
+the issues automatically, creating your commit again should succeed. Otherwise,
+you may need to address the corresponding issues manually first.
