Description: pep8 - Python style guide checker
=================================
pep8 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/
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 pep8.py file for this purpose.
* Comes with a comprehensive test suite.
Installation
------------
You can install, upgrade, uninstall pep8.py with these commands::
$ pip install pep8
$ pip install --upgrade pep8
$ pip uninstall pep8
There's also a package for Debian/Ubuntu, but it's not always the
latest version.
Example usage and output
------------------------
::
$ pep8 --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 pep8.py show the source code for each error, and
even the relevant text from PEP 8::
$ pep8 --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::
$ pep8 --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

Changelog
=========
1.4.6 (2013-07-02)
------------------
* 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)
* Correctly report other E12 errors when E123 is ignored. (Issue #103)
* 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)
* Do not crash when running AST checks and the document contains null bytes.
(Issue #184)
* Fix false positive E261/E262 when the file contains a BOM. (Issue #193)
* Fix E701, E702 and E703 not detected sometimes. (Issue #196)
* Fix E122 not detected in some cases. (Issue #201 and #208)
* 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)
------------------
* Report E227 or E228 instead of E225 for whitespace around bitwise, shift
or modulo operators. (Issue #166)
* Change the message for E226 to make clear that it is about arithmetic
operators.
* Fix a false positive E128 for continuation line indentation with tabs.
* Fix regression with the ``--diff`` option. (Issue #169)
* Fix the ``TestReport`` class to print the unexpected warnings and
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 to change 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 to construct 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
length E501 or continuation line indentation E12*. (Issue #27)
* Fix AssertionError when the source file contains an invalid line
ending ``"\r\r\n"``. (Issue #119)
* Read the ``[pep8]`` section of ``tox.ini`` or ``setup.cfg`` if present.
(Issue #93 and #141)
* Add the Sphinx-based documentation, and publish it
on http://pep8.readthedocs.org/. (Issue #105)
1.3.4 (2012-12-18)
------------------
* Fix false positive E124 and E128 with comments. (Issue #100)
* Fix error on stdin when running with bpython. (Issue #101)
* Fix false positive E401. (Issue #104)
* Report E231 for nested dictionary in list. (Issue #142)
* Catch E271 at the beginning of the line. (Issue #133)
* Fix false positive E126 for multi-line comments. (Issue #138)
* Fix false positive E221 when operator is preceded by a comma. (Issue #135)
* Fix ``--diff`` failing on one-line hunk. (Issue #137)
* Fix the ``--exclude`` switch for directory paths. (Issue #111)
* Use ``-`` filename to read from standard input. (Issue #128)
1.3.3 (2012-06-27)
------------------
* Fix regression with continuation line checker. (Issue #98)
1.3.2 (2012-06-26)
------------------
* Revert to the previous behaviour for ``--show-pep8``:
do not imply ``--first``. (Issue #89)
* Add E902 for IO errors. (Issue #87)
* Fix false positive for E121, and missed E124. (Issue #92)
* Set a sensible default path for config file on Windows. (Issue #95)
* Allow ``verbose`` in the configuration file. (Issue #91)
* Show the enforced ``max-line-length`` in the error message. (Issue #86)
1.3.1 (2012-06-18)
------------------
* Explain which configuration options are expected. Accept and recommend
the options names with hyphen instead of underscore. (Issue #82)
* Do not read the user configuration when used as a module
(except if ``config_file=True`` is passed to the ``StyleGuide`` constructor).
* Fix wrong or missing cases for the E12 series.
* Fix cases where E122 was missed. (Issue #81)
1.3 (2012-06-15)
----------------
.. warning::
The internal API is backwards incompatible.
* Remove global configuration and refactor the library around
a ``StyleGuide`` class; add the ability to configure various
reporters. (Issue #35 and #66)
* Read user configuration from ``~/.config/pep8``
and local configuration from ``./.pep8``. (Issue #22)
* Fix E502 for backslash embedded in multi-line string. (Issue #68)
* Fix E225 for Python 3 iterable unpacking (PEP 3132). (Issue #72)
* Enable the new checkers from the E12 series in the default
configuration.
* Suggest less error-prone alternatives for E712 errors.
* Rewrite checkers to run faster (E22, E251, E27).
* Fixed a crash when parsed code is invalid (too many
closing brackets).
* Fix E127 and E128 for continuation line indentation. (Issue #74)
* New option ``--format`` to customize the error format. (Issue #23)
* New option ``--diff`` to check only modified code. The unified
diff is read from STDIN. Example: ``hg diff | pep8 --diff``
(Issue #39)
* Correctly report the count of failures and set the exit code to 1
when the ``--doctest`` or the ``--testsuite`` fails.
* Correctly detect the encoding in Python 3. (Issue #69)
* Drop support for Python 2.3, 2.4 and 3.0. (Issue #78)
1.2 (2012-06-01)
----------------
* Add E121 through E128 for continuation line indentation. These
checks are disabled by default. If you want to force all checks,
use switch ``--select=E,W``. Patch by Sam Vilain. (Issue #64)
* 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``.
* Report all errors for each checker, instead of reporting only the
first occurence for each line.
* Option ``--show-pep8`` implies ``--first``.
1.1 (2012-05-24)
----------------
* Add E901 for syntax errors. (Issues #63 and #30)
* Add E271, E272, E273 and E274 for extraneous whitespace around
keywords. (Issue #57)
* Add ``tox.ini`` configuration file for tests. (Issue #61)
* Add ``.travis.yml`` configuration file for continuous integration.
(Issue #62)
1.0.1 (2012-04-06)
------------------
* Fix inconsistent version numbers.
1.0 (2012-04-04)
----------------
* Fix W602 ``raise`` to handle multi-char names. (Issue #53)
0.7.0 (2012-03-26)
------------------
* Now ``--first`` prints only the first occurence of each error.
The ``--repeat`` flag becomes obsolete because it is the default
behaviour. (Issue #6)
* Allow to specify ``--max-line-length``. (Issue #36)
* Make the shebang more flexible. (Issue #26)
* Add testsuite to the bundle. (Issue #25)
* Fixes for Jython. (Issue #49)
* Add PyPI classifiers. (Issue #43)
* Fix the ``--exclude`` option. (Issue #48)
* Fix W602, accept ``raise`` with 3 arguments. (Issue #34)
* Correctly select all tests if ``DEFAULT_IGNORE == ''``.
0.6.1 (2010-10-03)
------------------
* Fix inconsistent version numbers. (Issue #21)
0.6.0 (2010-09-19)
------------------
* Test suite reorganized and enhanced in order to check more failures
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)
* Fix E211 to reject ``v = dic['a'] ['b']``. (Issue #17)
* 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.
* Allow a new line before closing ``)``, ``}`` or ``]``. (Issue #5)
0.5.0 (2010-02-17)
------------------
* 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.
