autopep8 automatically formats Python code to conform to the `PEP 8`_ style
|
|
guide. It uses the pycodestyle_ utility to determine what parts of the code
|
|
needs to be formatted. autopep8 is capable of fixing most of the formatting
|
|
issues_ that can be reported by pycodestyle.

Installation
|
|
============
|
|
|
|
From pip::
|
|
|
|
$ pip install --upgrade autopep8
|
|
|
|
Consider using the ``--user`` option_.

|
|
|
|
Requirements
|
|
============

|
|
|
|
autopep8 also fixes some issues not found by pycodestyle_.
|
|
|
|
- Correct deprecated or non-idiomatic Python code (via ``lib2to3``). Use this
|
|
for making Python 2.7 code more compatible with Python 3. (This is triggered
|
|
if ``W690`` is enabled.)
|
|
- Normalize files with mixed line endings.
|
|
- Put a blank line between a class docstring and its first method
|
|
declaration. (Enabled with ``E301``.)
|
|
- Remove blank lines between a function declaration and its docstring. (Enabled
|
|
with ``E303``.)
|
|
|
|
autopep8 avoids fixing some issues found by pycodestyle_.
|
|
|
|
- ``E112``/``E113`` for non comments are reports of bad indentation that break
|
|
syntax rules. These should not be modified at all.
|
|
- ``E265``, which refers to spacing after comment hash, is ignored if the
|
|
comment looks like code. autopep8 avoids modifying these since they are not
|
|
real comments. If you really want to get rid of the pycodestyle_ warning,
|
|
consider just removing the commented-out code. (This can be automated via
|
|
eradicate_.)
|
|
|
|
.. _eradicate: https://github.com/myint/eradicate
|
|
|
|
|
|
More advanced usage
|
|
===================
|
|
|
|
By default autopep8 only makes whitespace changes. Thus, by default, it does
|
|
not fix ``E711`` and ``E712``. (Changing ``x == None`` to ``x is None`` may
|
|
change the meaning of the program if ``x`` has its ``__eq__`` method
|
|
overridden.) Nor does it correct deprecated code ``W6``. To enable these
|
|
more aggressive fixes, use the ``--aggressive`` option::
|
|
|
|
$ autopep8 --aggressive <filename>
|
|
|
|
Use multiple ``--aggressive`` to increase the aggressiveness level. For
|
|
example, ``E712`` requires aggressiveness level 2 (since ``x == True`` could be
|
|
changed to either ``x`` or ``x is True``, but autopep8 chooses the former).
|
|
|
|
``--aggressive`` will also shorten lines more aggressively. It will also remove
|
|
trailing whitespace more aggressively. (Usually, we don't touch trailing
|
|
whitespace in docstrings and other multiline strings. And to do even more
|
|
aggressive changes to docstrings, use docformatter_.)
|
|
|
|
.. _docformatter: https://github.com/myint/docformatter
|
|
|
|
To enable only a subset of the fixes, use the ``--select`` option. For example,
|
|
to fix various types of indentation issues::
|
|
|
|
$ autopep8 --select=E1,W1 <filename>
|
|
|
|
Similarly, to just fix deprecated code::
|
|
|
|
$ autopep8 --aggressive --select=W6 <filename>
|
|
|
|
The above is useful when trying to port a single code base to work with both
|
|
Python 2 and Python 3 at the same time.
|
|
|
|
If the file being fixed is large, you may want to enable verbose progress
|
|
messages::
|
|
|
|
$ autopep8 -v <filename>
|
|
|
|
Passing in ``--experimental`` enables the following functionality:
|
|
|
|
- Shortens code lines by taking its length into account
|
|
|
|
::
|
|
|
|
$ autopep8 --experimental <filename>
|
|
|
|
Use as a module
|
|
===============
|
|
|
|
The simplest way of using autopep8 as a module is via the ``fix_code()``
|
|
function:
|
|
|
|
>>> import autopep8
|
|
>>> autopep8.fix_code('x= 123\n')
|
|
'x = 123\n'
|
|
|
|
Or with options:
|
|
|
|
>>> import autopep8
|
|
>>> autopep8.fix_code('x.has_key(y)\n',
|
|
... options={'aggressive': 1})
|
|
'y in x\n'
|
|
>>> autopep8.fix_code('print( 123 )\n',
|
|
... options={'ignore': ['E']})
|
|
'print( 123 )\n'
|
|
|
|
|
|
Configuration
|
|
=============
|
|
|
|
By default, if ``$HOME/.config/pycodestyle`` (``~\.pycodestyle`` in Windows
|
|
environment) exists, it will be used as global configuration file.
|
|
Alternatively, you can specify the global configuration file with the
|
|
``--global-config`` option.
|
|
|
|
Also, if ``setup.cfg``, ``tox.ini``, ``.pep8`` and ``.flake8`` files exist
|
|
in the directory where the target file exists, it will be used as the
|
|
configuration file.
|
|
|
|
``pep8``, ``pycodestyle``, and ``flake8`` can be used as a section.
|
|
|
|
configuration file example::
|
|
|
|
[pycodestyle]
|
|
max_line_length = 120
|
|
ignore = E501
|
|
|
|
pyproject.toml
|
|
--------------
|
|
|
|
autopep8 can also use ``pyproject.toml``.
|
|
section must use ``[tool.autopep8]``, and ``pyproject.toml`` takes precedence
|
|
over any other configuration files.
|
|
|
|
configuration file example::
|
|
|
|
[tool.autopep8]
|
|
max_line_length = 120
|
|
ignore = "E501,W6" # or ["E501", "W6"]
|
|
|
|
|
|
Testing
|
|
=======
|
|
|
|
Test cases are in ``test/test_autopep8.py``. They can be run directly via
|
|
``python test/test_autopep8.py`` or via tox_. The latter is useful for
|
|
testing against multiple Python interpreters. (We currently test against
|
|
CPython versions 2.7, 3.6 3.7 and 3.8. We also test against PyPy.)
|
|
|
|
.. _`tox`: https://pypi.org/project/tox/
|
|
|
|
Broad spectrum testing is available via ``test/acid.py``. This script runs
|
|
autopep8 against Python code and checks for correctness and completeness of the
|
|
code fixes. It can check that the bytecode remains identical.
|
|
``test/acid_pypi.py`` makes use of ``acid.py`` to test against the latest
|
|
released packages on PyPI.
|
|
|
|
|
|
Troubleshooting
|
|
===============
|
|
|
|
``pkg_resources.DistributionNotFound``
|
|
--------------------------------------
|
|
|
|
If you are using an ancient version of ``setuptools``, you might encounter
|
|
``pkg_resources.DistributionNotFound`` when trying to run ``autopep8``. Try
|
|
upgrading ``setuptools`` to workaround this ``setuptools`` problem::
|
|
|
|
$ pip install --upgrade setuptools
|
|
|
|
Use ``sudo`` if you are installing to the system.
