pycodestyle is a tool to check your Python code against some of the style
conventions in `PEP 8`_.

.. _PEP 8: http://www.python.org/dev/peps/pep-0008/

.. note::

    This package used to be called ``pep8`` but was renamed to ``pycodestyle``
    to reduce confusion. Further discussion can be found `in the issue where
    Guido requested this
    change <https://github.com/PyCQA/pycodestyle/issues/466>`_, or in the
    lightning talk at PyCon 2016 by @IanLee1521:
    `slides <https://speakerdeck.com/ianlee1521/pep8-vs-pep-8>`_
    `video <https://youtu.be/PulzIT8KYLk?t=36m>`_.

Features
--------

* Plugin architecture: Adding new checks is easy.

* Parseable output: Jump to error location in your editor.

* Small: Just one Python file, requires only stdlib. You can use just
  the ``pycodestyle.py`` file for this purpose.

* Comes with a comprehensive test suite.

Installation
------------

You can install, upgrade, and uninstall ``pycodestyle.py`` with these commands::

  $ pip install pycodestyle
  $ pip install --upgrade pycodestyle
  $ pip uninstall pycodestyle

There's also a package for Debian/Ubuntu, but it's not always the
latest version.

Example usage and output
------------------------

::

  $ pycodestyle --first optparse.py
  optparse.py:69:11: E401 multiple imports on one line
  optparse.py:77:1: E302 expected 2 blank lines, found 1
  optparse.py:88:5: E301 expected 1 blank line, found 0
  optparse.py:222:34: W602 deprecated form of raising exception
  optparse.py:347:31: E211 whitespace before '('
  optparse.py:357:17: E201 whitespace after '{'
  optparse.py:472:29: E221 multiple spaces before operator
  optparse.py:544:21: W601 .has_key() is deprecated, use 'in'

You can also make ``pycodestyle.py`` show the source code for each error, and
even the relevant text from PEP 8::

  $ pycodestyle --show-source --show-pep8 testsuite/E40.py
  testsuite/E40.py:2:10: E401 multiple imports on one line
  import os, sys
           ^
      Imports should usually be on separate lines.

      Okay: import os\nimport sys
      E401: import sys, os


Or you can display how often each error was found::

  $ pycodestyle --statistics -qq Python-2.5/Lib
  232     E201 whitespace after '['
  599     E202 whitespace before ')'
  631     E203 whitespace before ','
  842     E211 whitespace before '('
  2531    E221 multiple spaces before operator
  4473    E301 expected 1 blank line, found 0
  4006    E302 expected 2 blank lines, found 1
  165     E303 too many blank lines (4)
  325     E401 multiple imports on one line
  3615    E501 line too long (82 characters)
  612     W601 .has_key() is deprecated, use 'in'
  1188    W602 deprecated form of raising exception

------------------

Bug fixes:

* Fix a crash with E125 on multi-line strings. (Issue #263)


1.5 (2014-03-26)
----------------

* Report E131 instead of E121 / E126 if the hanging indent is not
  consistent within the same continuation block.  It helps when
  error E121 or E126 is in the ``ignore`` list.

  with a tab. (Issue #237)

* Fix a rare false positive W602. (Issue #34)


1.4.6 (2013-07-02)
------------------

Changes:

* Honor ``# noqa`` for errors E711 and E712. (Issue #180)

* When both a ``tox.ini`` and a ``setup.cfg`` are present in the project
  directory, merge their contents.  The ``tox.ini`` file takes
  precedence (same as before). (Issue #182)

* Give priority to ``--select`` over ``--ignore``. (Issue #188)

* Compare full path when excluding a file. (Issue #186)

* New option ``--hang-closing`` to switch to the alternative style of
  closing bracket indentation for hanging indent.  Add error E133 for
  closing bracket which is missing indentation. (Issue #103)

* Accept both styles of closing bracket indentation for hanging indent.
  Do not report error E123 in the default configuration. (Issue #103)

Bug fixes:

* Do not crash when running AST checks and the document contains null bytes.
  (Issue #184)

* Fix false positive E121 with multiple brackets. (Issue #203)


1.4.5 (2013-03-06)
------------------

* When no path is specified, do not try to read from stdin.  The feature
  was added in 1.4.3, but it is not supported on Windows.  Use ``-``
  filename argument to read from stdin.  This usage is supported
  since 1.3.4. (Issue #170)

* Do not require ``setuptools`` in setup.py.  It works around an issue
  with ``pip`` and Python 3. (Issue #172)

* Add ``__pycache__`` to the ignore list.

* Change misleading message for E251. (Issue #171)

* Do not report false E302 when the source file has a coding cookie or a
  comment on the first line. (Issue #174)

* Reorganize the tests and add tests for the API and for the command line
  usage and options. (Issues #161 and #162)

* Ignore all checks which are not explicitly selected when ``select`` is
  passed to the ``StyleGuide`` constructor.


1.4.4 (2013-02-24)
------------------

  errors.


1.4.3 (2013-02-22)
------------------

* Hide the ``--doctest`` and ``--testsuite`` options when installed.

* Fix crash with AST checkers when the syntax is invalid. (Issue #160)

* Read from standard input if no path is specified.

* Initiate a graceful shutdown on ``Control+C``.

* Allow changing the ``checker_class`` for the ``StyleGuide``.


1.4.2 (2013-02-10)
------------------

* Support AST checkers provided by third-party applications.

* Register new checkers with ``register_check(func_or_cls, codes)``.

* Allow constructing a ``StyleGuide`` with a custom parser.

* Accept visual indentation without parenthesis after the ``if``
  statement. (Issue #151)

* Fix UnboundLocalError when using ``# noqa`` with continued lines.
  (Issue #158)

* Re-order the lines for the ``StandardReport``.

* Expand tabs when checking E12 continuation lines. (Issue #155)

* Refactor the testing class ``TestReport`` and the specific test
  functions into a separate test module.


1.4.1 (2013-01-18)
------------------

* Allow sphinx.ext.autodoc syntax for comments. (Issue #110)

* Report E703 instead of E702 for the trailing semicolon. (Issue #117)

* Honor ``# noqa`` in addition to ``# nopep8``. (Issue #149)

* Expose the ``OptionParser`` factory for better extensibility.


1.4 (2012-12-22)
----------------

* Report E226 instead of E225 for optional whitespace around common
  operators (``*``, ``**``, ``/``, ``+`` and ``-``).  This new error
  code is ignored in the default configuration because PEP 8 recommends
  to "use your own judgement". (Issue #96)

* Lines with a ``# nopep8`` at the end will not issue errors on line

* Add E721 for direct type comparisons. (Issue #47)

* Add E711 and E712 for comparisons to singletons. (Issue #46)

* Fix spurious E225 and E701 for function annotations. (Issue #29)

* Add E502 for explicit line join between brackets.

* Fix E901 when printing source with ``--show-source``.

----------------

* Fix W602 ``raise`` to handle multi-char names. (Issue #53)


0.7.0 (2012-03-26)
------------------

* Now ``--first`` prints only the first occurrence of each error.
  The ``--repeat`` flag becomes obsolete because it is the default
  behaviour. (Issue #6)

* Allow specifying ``--max-line-length``. (Issue #36)

* Make the shebang more flexible. (Issue #26)

* Add testsuite to the bundle. (Issue #25)

* Fixes for Jython. (Issue #49)

  with fewer test files.  Read the ``run_tests`` docstring for details
  about the syntax.

* Fix E225: accept ``print >>sys.stderr, "..."`` syntax.

* Fix E501 for lines containing multibyte encoded characters. (Issue #7)

* Fix E221, E222, E223, E224 not detected in some cases. (Issue #16)

* Exit code is always 1 if any error or warning is found. (Issue #10)

* ``--ignore`` checks are now really ignored, especially in
  conjunction with ``--count``. (Issue #8)

* Blank lines with spaces yield W293 instead of W291: some developers
  want to ignore this warning and indent the blank lines to paste their
  code easily in the Python interpreter.

* Fix E301: do not require a blank line before an indented block. (Issue #14)

* Fix E203 to accept NumPy slice notation ``a[0, :]``. (Issue #13)

* Performance improvements.

* Fix decoding and checking non-UTF8 files in Python 3.

* Fix E225: reject ``True+False`` when running on Python 3.

* Fix an exception when the line starts with an operator.

* Changed the ``--count`` switch to print to sys.stderr and set
  exit code to 1 if any error or warning is found.

* E241 and E242 are removed from the standard checks. If you want to
  include these checks, use switch ``--select=E,W``. (Issue #4)

* Blank line is not mandatory before the first class method or nested
  function definition, even if there's a docstring. (Issue #1)

* Add the switch ``--version``.

* Fix decoding errors with Python 3. (Issue #13 [1]_)

* Add ``--select`` option which is mirror of ``--ignore``.

* Add checks E261 and E262 for spaces before inline comments.

* New check W604 warns about deprecated usage of backticks.

* New check W603 warns about the deprecated operator ``<>``.

* Performance improvement, due to rewriting of E225.

* E225 now accepts:

  - no whitespace after unary operator or similar. (Issue #9 [1]_)

  - lambda function with argument unpacking or keyword defaults.

* Reserve "2 blank lines" for module-level logical blocks. (E303)

* Allow multi-line comments. (E302, issue #10 [1]_)


0.4.2 (2009-10-22)
------------------

* Decorators on classes and class methods are OK now.

----------------

* Support for all versions of Python from 2.3 to 3.1.

* New and greatly expanded self tests.

* Added ``--count`` option to print the total number of errors and warnings.

* Further improvements to the handling of comments and blank lines.
  (Issue #1 [1]_ and others changes.)

* Check all py files in directory when passed a directory (Issue
  #2 [1]_). This also prevents an exception when traversing directories
  with non ``*.py`` files.

* E231 should allow commas to be followed by ``)``. (Issue #3 [1]_)

* Spaces are no longer required around the equals sign for keyword
  arguments or default parameter values.
