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

closing bracket indentation for hanging indent. Add error E133 for

closing bracket which is missing indentation. (Issue #103)

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)

usage and options. (Issues #161 and #162)

* 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``.

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.

* 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 occurrence 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 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)

* 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.

* 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.

0.4 (2009-10-20)

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

* 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.
