(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. * 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. .. [1] These issues refer to the `previous issue tracker`__. .. __: http://github.com/cburroughs/pep8.py/issues 0.3.1 (2009-09-14) ------------------ * Fixes for comments: do not count them when checking for blank lines between items. * Added setup.py for pypi upload and easy_installability. 0.2 (2007-10-16) ---------------- * Loads of fixes and improvements. 0.1 (2006-10-01) ---------------- * First release. pep8-1.4.6/docs/0000755000076500000240000000000012164557320015513 5ustar florentxiclunastaff00000000000000pep8-1.4.6/docs/advanced.rst0000644000076500000240000000445312065354422020016 0ustar florentxiclunastaff00000000000000.. currentmodule:: pep8 ============== Advanced usage ============== Automated tests --------------- You can also execute `pep8` tests from Python code. For example, this can be highly useful for automated testing of coding style conformance in your project:: import unittest import pep8 class TestCodeFormat(unittest.TestCase): def test_pep8_conformance(self): """Test that we conform to PEP8.""" pep8style = pep8.StyleGuide(quiet=True) result = pep8style.check_files(['file1.py', 'file2.py']) self.assertEqual(result.total_errors, 0, "Found code style errors (and warnings).") If you are using `nosetests` for running tests, remove `quiet=True` since Nose suppresses stdout. There's also a shortcut for checking a single file:: import pep8 fchecker = pep8.Checker('testsuite/E27.py', show_source=True) file_errors = fchecker.check_all() print("Found %s errors (and warnings)" % file_errors) Skip file header ---------------- Another example is related to the `feature request #143 `_: skip a number of lines at the beginning and the end of a file. This use case is easy to implement through a custom wrapper for the PEP 8 library:: #!python import pep8 LINES_SLICE = slice(14, -20) class PEP8(pep8.StyleGuide): """This subclass of pep8.StyleGuide will skip the first and last lines of each file.""" def input_file(self, filename, lines=None, expected=None, line_offset=0): if lines is None: assert line_offset == 0 line_offset = LINES_SLICE.start or 0 lines = pep8.readlines(filename)[LINES_SLICE] return super(PEP8, self).input_file( filename, lines=lines, expected=expected, line_offset=line_offset) if __name__ == '__main__': pep8style = PEP8(parse_argv=True, config_file=True) report = pep8style.check_files() if report.total_errors: raise SystemExit(1) This module declares a lines' window which skips 14 lines at the beginning and 20 lines at the end. If there's no line to skip at the end, it could be changed with ``LINES_SLICE = slice(14, None)`` for example. You can save it in a file and use it with the same options as the original ``pep8``. pep8-1.4.6/docs/api.rst0000644000076500000240000000502712137054613017017 0ustar florentxiclunastaff00000000000000======== pep8 API ======== .. module:: pep8 The library provides classes which are usable by third party tools. .. contents:: :local: .. _main_classes: Checker Classes --------------- The :class:`StyleGuide` class is used to configure a style guide checker instance to check multiple files.

Fork away! * `Source code `_ and `issue tracker `_ on GitHub. * `Continuous tests `_ against Python 2.5 through 3.3 and PyPy, on `Travis-CI platform `_. .. _available on GitHub: https://github.com/jcrocholl/pep8 Contribute ~~~~~~~~~~ You can add checks to this program by writing plugins. Each plugin is a simple function that is called for each line of source code, either physical or logical. Physical line: * Raw line of text from the input file. Logical line: * Multi-line statements converted to a single line. * Stripped left and right. * Contents of strings replaced with ``"xxx"`` of same length. * Comments removed. The check function requests physical or logical lines by the name of the first argument:: def maximum_line_length(physical_line) def extraneous_whitespace(logical_line) def blank_lines(logical_line, blank_lines, indent_level, line_number) The last example above demonstrates how check plugins can request additional information with extra arguments. All attributes of the :class:`Checker` object are available. Some examples: * ``lines``: a list of the raw lines from the input file * ``tokens``: the tokens that contribute to this logical line * ``line_number``: line number in the input file * ``blank_lines``: blank lines before this one * ``indent_char``: first indentation character in this file (``" "`` or ``"\t"``) * ``indent_level``: indentation (with tabs expanded to multiples of 8) * ``previous_indent_level``: indentation on previous line * ``previous_logical``: previous logical line The docstring of each check function shall be the relevant part of text from `PEP 8`_. It is printed if the user enables ``--show-pep8``. Several docstrings contain examples directly from the `PEP 8`_ document. :: Okay: spam(ham[1], {eggs: 2}) E201: spam( ham[1], {eggs: 2}) These examples are verified automatically when pep8.py is run with the ``--doctest`` option. You can add examples for your own check functions. The format is simple: ``"Okay"`` or error/warning code followed by colon and space, the rest of the line is example source code. If you put ``'r'`` before the docstring, you can use ``\n`` for newline and ``\t`` for tab. Then be sure to pass the tests:: $ python pep8.py --testsuite testsuite $ python pep8.py --doctest $ python pep8.py --verbose pep8.py .. _PEP 8: http://www.python.org/dev/peps/pep-0008/ Changes ~~~~~~~ .. include:: ../CHANGES.txt :start-line: 3 pep8-1.4.6/docs/index.rst0000644000076500000240000000345612065361363017364 0ustar florentxiclunastaff00000000000000.. pep8 documentation master file pep8's documentation ==================== *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/ Contents: .. toctree:: :maxdepth: 2 intro advanced API developer * Online documentation: http://pep8.readthedocs.org/ * Source code and issue tracker: https://github.com/jcrocholl/pep8 Indices and tables ================== * :ref:`genindex` * :ref:`search` Credits ======= Created by Johann C.

You can use just the pep8.py file for this purpose. * Comes with a comprehensive test suite. Disclaimer ---------- This utility does not enforce every single rule of PEP 8. It helps to verify that some coding conventions are applied but it does not intend to be exhaustive. Some rules cannot be expressed with a simple algorithm, and other rules are only guidelines which you could circumvent when you need to. Always remember this statement from `PEP 8`_: *A style guide is about consistency. Consistency with this style guide is important. Consistency within a project is more important. Consistency within one module or function is most important.* Among other things, these features are currently not in the scope of the ``pep8`` library: * **naming conventions**: this kind of feature is supported through plugins. Install `flake8 `_ and the `pep8-naming extension `_ to use this feature. * **docstring conventions**: they are not in the scope of this library; see the `pep257 project `_. * **automatic fixing**: see the section *PEP8 Fixers* in the :ref:`related tools ` page. 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:: $ sudo apt-get install pep8 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 Quick help is available on the command line:: $ pep8 -h Usage: pep8 [options] input ... Options: --version show program's version number and exit -h, --help show this help message and exit -v, --verbose print status messages, or debug with -vv -q, --quiet report only file names, or nothing with -qq --first show first occurrence of each error --exclude=patterns exclude files or directories which match these comma separated patterns (default: .svn,CVS,.bzr,.hg,.git) --filename=patterns when parsing directories, only check filenames matching these comma separated patterns (default: *.py) --select=errors select errors and warnings (e.g. E,W6) --ignore=errors skip errors and warnings (e.g. E4,W) --show-source show source code for each error --show-pep8 show text of PEP 8 for each error (implies --first) --statistics count errors and warnings --count print total number of errors and warnings to standard error and set exit code to 1 if total is not null --max-line-length=n set maximum allowed line length (default: 79) --hang-closing hang closing bracket instead of matching indentation of opening bracket's line --format=format set the error format [default|pylint|] --diff report only lines changed according to the unified diff received on STDIN Testing Options: --benchmark measure processing speed Configuration: The project options are read from the [pep8] section of the tox.ini file or the setup.cfg file located in any parent folder of the path(s) being processed. Allowed options are: exclude, filename, select, ignore, max-line-length, hang-closing, count, format, quiet, show-pep8, show-source, statistics, verbose. --config=path user config file location (default: ~/.config/pep8) Configuration ------------- The behaviour may be configured at two levels. The user settings are read from the ``~/.config/pep8`` file. Example:: [pep8] ignore = E226,E302,E41 max-line-length = 160 At the project level, a ``tox.ini`` file or a ``setup.cfg`` file is read if present (``.pep8`` file is also supported, but it is deprecated). If none of these files have a ``[pep8]`` section, no project specific configuration is loaded. If the ``ignore`` option is not in the configuration and not in the arguments, only the error codes ``E226`` and ``E241/E242`` are ignored (see below).

because they are not rules unanimously accepted, and `PEP 8`_ does not enforce them. The check **E133** is mutually exclusive with check **E123**. Use switch ``--hang-closing`` to report **E133** instead of **E123**. **(^)** These checks can be disabled at the line level using the ``# noqa`` special comment. This possibility should be reserved for special cases. *Special cases aren't special enough to break the rules.* Note: most errors can be listed with such one-liner:: $ python pep8.py --first --select E,W testsuite/ --format '%(code)s: %(text)s' .. _related-tools: Related tools ------------- The `flake8 checker `_ is a wrapper around ``pep8`` and similar tools.

Rocholl Author-email: johann@rocholl.net License: Expat license 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 Links ----- .. image:: https://api.travis-ci.org/jcrocholl/pep8.png?branch=master :target: https://travis-ci.org/jcrocholl/pep8 :alt: Build status * `Read the documentation `_ * `Fork me on GitHub `_ 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. * 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. .. [1] These issues refer to the `previous issue tracker`__. .. __: http://github.com/cburroughs/pep8.py/issues 0.3.1 (2009-09-14) ------------------ * Fixes for comments: do not count them when checking for blank lines between items. * Added setup.py for pypi upload and easy_installability. 0.2 (2007-10-16) ---------------- * Loads of fixes and improvements. 0.1 (2006-10-01) ---------------- * First release.

Rocholl Author-email: johann@rocholl.net License: Expat license 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.

(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. * 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. ..
