Styling 😎
**********

Each language in the Apache Arrow project follows its own style guides.

In this section we will provide links to the existing documentation
to make it easier for you to find the relevant information about
linters and styling of the code.

.. tab-set::

   .. tab-item:: PyArrow

      :ref:`python-coding-style`.

   .. tab-item:: R package

      For the R package you can use
      `air <https://posit-dev.github.io/air/>`_ to format the code,
      and

      ``{lintr}``
      to check if the code follows the
      `tidyverse style <https://style.tidyverse.org/>`_.

      The instructions on how to use `air` and ``{lintr}``
      can be found in the
      `Styling and Linting section of the Common developer workflow tasks <https://arrow.apache.org/docs/r/articles/developers/workflow.html#styling-and-linting>`_.

Pre-commit
----------

It is useful to set up `pre-commit <https://pre-commit.com/>`_,
a multi-language package manager for pre-commit hooks. It will
check your code and will stop the commit process, described in
the following section, if there are any errors.

- `Pre-commit installation instructions <https://pre-commit.com/#installation>`_
- `Pre-commit hooks <https://pre-commit.com/hooks.html>`_
