pep8radius
----------
`PEP8 <http://legacy.python.org/dev/peps/pep-0008/>`__ clean only the
parts of the files touched since the last commit, a previous commit or
(the merge-base of) a branch.

Fixing the entire project of PEP8 infractions ("PEP8 storms") can lead
to merge conflicts, add noise to merges / pull requests and break (git)
blame. pep8radius solves this problem by fixing only those PEP8
infractions incontained on the lines of the project which you've been
working, leaving these sections "better than you found it" whilst
keeping your commits focused on the areas of the codebase you were
actually working on.
Installation
------------
From pip:
.. code:: sh
$ pip install pep8radius
Usage
-----

Usage gif of pep8radius
- Move to project directory
- Make some changes to the project
- Run ``pep8radius --diff # view a diff of proposed fixed``
- Run ``pep8radius --in-place # apply the fixes``
- Commit your changes
Against a branch you can use the same syntax as with git diff:
.. code:: sh
$ pep8radius master # branch name to compare against (compares against merge-base)
$ pep8radius c12166f # commit hash
$ pep8radius master --in-place # these work with other options too
You can also fix docstrings
(`PEP257 <http://legacy.python.org/dev/peps/pep-0257/>`__) using the
`docformatter <https://pypi.python.org/pypi/docformatter>`__ option:
.. code:: sh
$ pep8radius --docformatter --diff
*Note: can also use ``btyfi`` alias for ``pep8radius``.*
--------------
It can be nice to pipe the diff to
`cdiff <https://pypi.python.org/pypi/cdiff>`__ (which makes diffs pretty
and has lots of options):
.. code:: sh
$ pep8radius --diff --no-color | cdiff
$ pep8radius --diff --no-color | cdiff --side-by-side
You can get strange results if you don't use no-color.
I actually use the following git alias (which allows ``git rad`` and
``git rad -i``):
.. code:: sh
[alias]
rad = !pep8radius master --diff --no-color $@ | cdiff --side-by-side
which outputs the corrections as follows:

git rad
--------------
You can pipe in a diff directly, to fix the lines modified in it with
``--from-diff`` (this is somewhat experimental, please report failing
diffs!).
For example:
.. code:: sh
$ git diff master | pep8radius --diff --from-diff=-
Requirements
------------
pep8radius uses `autopep8 <https://pypi.python.org/pypi/autopep8>`__,
and in turn `pep8 <https://pypi.python.org/pypi/pep8>`__. The
docformatter option, to fix docstrings, uses
`docformatter <https://pypi.python.org/pypi/docformatter>`__.
VCS Support
-----------
`Git <http://git-scm.com/>`__, `Mecurial
(hg) <http://mercurial.selenic.com/>`__, (tentatively)
`Bazaar <http://bazaar.canonical.com/en/>`__. Please request support for
other version control systems on
`github <https://github.com/hayd/pep8radius/issues/5>`__.
Options
-------
.. code:: sh
$ pep8radius --help
usage: pep8radius [-h] [--version] [-d] [-i] [--no-color] [-v]
[--from-diff DIFF] [-p n] [-a] [--experimental]
[--exclude globs] [--list-fixes] [--ignore errors]
[--select errors] [--max-line-length n] [--indent-size n]
[-f] [--no-blank] [--pre-summary-newline] [--force-wrap]
[--global-config GLOBAL_CONFIG] [--ignore-local-config]
[rev]
PEP8 clean only the parts of the files which you have touched since the last
commit, a previous commit or (the merge-base of) a branch.
positional arguments:
rev commit or name of branch to compare against
optional arguments:
-h, --help show this help message and exit
--version print version number and exit
-d, --diff print the diff of fixed source vs original
-i, --in-place make the fixes in place; modify the files
--no-color do not print diffs in color (default is to use color)
-v, --verbose print verbose messages; multiple -v result in more
verbose messages (one less -v is passed to autopep8)
--from-diff DIFF Experimental: rather than calling out to version
control, just pass in a diff; the modified lines will
be fixed
pep8:
Pep8 options to pass to autopep8.
-p n, --pep8-passes n
maximum number of additional pep8 passes (default:
infinite)
-a, --aggressive enable non-whitespace changes; multiple -a result in
more aggressive changes
--experimental enable experimental fixes
--exclude globs exclude file/directory names that match these comma-
separated globs
--list-fixes list codes for fixes and exit; used by --ignore and
--select
--ignore errors do not fix these errors/warnings (default: E24)
--select errors fix only these errors/warnings (e.g. E4,W)
--max-line-length n set maximum allowed line length (default: 79)
--indent-size n number of spaces per indent level (default 4)
docformatter:
Fix docstrings for PEP257.
-f, --docformatter Use docformatter
--no-blank Do not add blank line after description
--pre-summary-newline
add a newline before the summary of a multi-line
docstring
--force-wrap force descriptions to be wrapped even if it may result
in a mess
config:
Change default options based on global or local (project) config files.
--global-config filename
path to global pep8 config file; if this file does not
exist then this is ignored (default: ~/.config/pep8)
--ignore-local-config
don't look for and apply local config files; if not
passed, defaults are updated with any config files in
the project's root dir
Run before you commit, against a previous commit or branch before merging.
*For more information about these options see
`autopep8 <https://pypi.python.org/pypi/autopep8>`__.*
As a module
-----------
Pep8radius also exports lightweight wrappers around autopep8 so that you
can fix line ranges of your code with ``fix_code`` or ``fix_file``.
Here's the example "bad code" from `autopep8's
README <https://github.com/hhatto/autopep8/blob/master/README.rst#usage>`__:
.. code:: py
import math, sys;
def example1():
####This is a long comment. This should be wrapped to fit within 72 characters.
some_tuple=( 1,2, 3,'a' );
some_variable={'long':'Long code lines should be wrapped within 79 characters.',
'other':[math.pi, 100,200,300,9876543210,'This is a long string that goes on'],
'more':{'inner':'This whole logical line should be wrapped.',some_tuple:[1,
20,300,40000,500000000,60000000000000000]}}
return (some_tuple, some_variable)
def example2(): return {'has_key() is deprecated':True}.has_key({'f':2}.has_key(''));
class Example3( object ):
def __init__ ( self, bar ):
#Comments should have a space after the hash.
if bar : bar+=1; bar=bar* bar ; return bar
else:
some_string = """
Indentation in multiline strings should not be touched.
Only actual code should be reindented.
"""
return (sys.path, some_string)
You can pep8 fix just the line ranges 1-1 (the imports) and 12-21 (the
``Example3``\ class) with
``pep8radius.fix_code(code, [(1, 1), (12, 21)])`` (where code is a
string of the above), which returns the code fixed within those ranges:
.. code:: py
import math
import sys
def example1():
####This is a long comment. This should be wrapped to fit within 72 characters.
some_tuple=( 1,2, 3,'a' );
some_variable={'long':'Long code lines should be wrapped within 79 characters.',
'other':[math.pi, 100,200,300,9876543210,'This is a long string that goes on'],
'more':{'inner':'This whole logical line should be wrapped.',some_tuple:[1,
20,300,40000,500000000,60000000000000000]}}
return (some_tuple, some_variable)
def example2(): return {'has_key() is deprecated':True}.has_key({'f':2}.has_key(''));
class Example3(object):
def __init__(self, bar):
# Comments should have a space after the hash.
if bar:
bar += 1
bar = bar * bar
return bar
else:
some_string = """
Indentation in multiline strings should not be touched.
Only actual code should be reindented.
"""
return (sys.path, some_string)
You can use ``fix_file`` to do this directly on a file, which gives you
the option of doing this in place.
.. code:: py
pep8radius.fix_code('code.py', [(1, 1), (12, 21)], in_place=True)
You can also pass the same arguments to pep8radius script itself using
the ``parse_args``. For example ignoring long lines (E501) and use the
options from your global config files:
.. code:: py
args = pep8radius.parse_args(['--ignore=E501', '--ignore-local-config'],
apply_config=True)
pep8radius.fix_code(code, [(1, 1), (12, 21)], options=args)
