pycodestyle (formerly called pep8) - Python style guide checker
===============================================================
pycodestyle is a tool to check your Python code against some of the style
conventions in [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 [here](https://github.com/PyCQA/pycodestyle/issues/466).
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 ``pycodestyle.py`` with ``pip``:
$ pip install pycodestyle
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
^
Place imports 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
