================= Flake8 Spellcheck

|CircleCI| |Black| |PyPi|

Flake8 Plugin that spellchecks variables, functions, classes and other bits of your python code.

You can create an allowlist for words that are specific to your project simply by adding them a .spellcheck-allowlist file in the root of your project directory. Each word you add should be separated by a newline.

Spelling is assumed to be in en_US.

This plugin supports python 3.8+

Codes

• SC100 - Spelling error in comments
• SC200 - Spelling error in name (e.g. variable, function, class)

Enable Django support

You can enable support for a Django dictionary by adding the following to your flake8 configuration (e.g. your .flake8 file):

.. code-block:: ini

[flake8]
dictionaries = en_US,python,technical,django

Enable pandas support

You can enable support for pandas DataFrames by adding the following to your flake8 configuration (e.g. your .flake8 file):

.. code-block:: ini

[flake8]
dictionaries = en_US,python,technical,pandas

Specify Targets

Both comments and names (variable names, function names...) are spellchecked by default. You can specify what targets to spellcheck in your flake8 configuration (e.g. in your .flake8 file):

.. code-block:: ini

[flake8] spellcheck-targets = comments

The above configuration would only spellcheck comments

.. code-block:: ini

[flake8] spellcheck-targets = names

The above configuration would only spellcheck names

Specify Allowlist

You can specify a list of allowed words - spellcheck will then not raise errors when those words are encountered. You can define the list of allowed words either as a file or as a configuration parameter.

By default, spellcheck will try to load a .spellcheck-allowlist file in the root of your project. You can override the file name using the --spellcheck-allowlist-file CLI parameter, or in your flake8 configuration (e.g. in your .flake8 file):

.. code-block:: ini

[flake8] spellcheck-allowlist-file = your-allowlist-file

You can also define the allowlist directly using the --spellcheck-allowlist CLI parameter (this takes a comma-separated list of words to allow) or using the flake8 configuration (e.g. in your .flake8 file):

.. code-block:: ini

[flake8] spellcheck-allowlist = your, allowed, words

Ignore Rules

.. code-block:: ini

[flake8] ignore = SC100, SC200

Contributing

If you have found word(s) which are listed as a spelling error but are actually correct terms used in python or in technical implementations (e.g. http), then you can very easily contribute by adding those word(s) to the appropriate dictionaries:

• python dictionary <flake8_spellcheck/python.txt>_
• technical dictionary <flake8_spellcheck/technical.txt>_
• django dictionary <flake8_spellcheck/django.txt>_
• pandas dictionary <flake8_spellcheck/pandas.txt>_

Before you submit a PR, it is recommended to run check-sorting.sh in the root of this repository, to verify that all the dictionary files are still sorted correctly. Sorting is enforced by CI, so you'll need to make sure the files are sorted before your PR can be merged.

Development

• Install poetry <https://github.com/python-poetry>__
• Install golang <https://go.dev/doc/install>__ (required by some of our pre-commit hooks)
• Run poetry install
• Run poetry run pre-commit install --install-hooks

You can run tests with poetry run pytest.
