Pep8ify: Clean your code with ease

Pep8ify is a library that modifies python source code to conform to pep8.

Installation

This library currently works with python 2.7, 3.2, and 3.3.

To install pep8ify, simply:

$ pip install pep8ify

Usage

To print a diff of changes that pep8ify will make against a particular source file or directory:

$ pep8ify source_folder

To have those changes written to the files:

$ pep8ify -w source_folder

By default, this will create backup files for each file that will be changed. You can add the -n option to not create the backups. Please do not do this if you are not using a version control system. Although this code is well-tested, there are most likely bugs still.

For more options about running particular fixers, read the lib2to3 documentation. This library is built on top of that one.

Fixes

A list of the available fixers can be found with the following:

$ pep8ify -l
Available transformations for the -f/--fix option:
blank_lines
compound_statements
extraneous_whitespace
imports_on_separate_lines
indentation
maximum_line_length
missing_newline
missing_whitespace
tabs
trailing_blank_lines
trailing_whitespace
whitespace_around_operator
whitespace_before_inline_comment
whitespace_before_parameters

All of these are set to run by default except for 'maximum_line_length'. To run all fixes including 'maximum_line_length', run:

$ pep8ify -f all -f maximum_line_length example.py
