This is a pre-commit hook for Git that checks the code to be committed for Python PEP8 style compliance. The hook will prevent the commit in case style violations are detected.

1. Install the pep8 program: pip install pep8
2. Save pre-commit as your_project/.git/hooks/pre-commit
3. Mark pre-commit executable: chmod +x your_project/.git/hooks/pre-commit

The hook can be overridden: $ git commit --no-verify

Currently, the following PEP8 codes are checked for:

• E111 indentation is not a multiple of four
• E125 continuation line does not distinguish itself from next logical line
• E203 whitespace before ':'
• E261 at least two spaces before inline comment
• E262 inline comment should start with '# '
• E301 expected 1 blank line, found 0
• E302 expected 2 blank lines, found 1
• E303 too many blank lines (2)
• E502 the backslash is redundant between brackets
• E701 multiple statements on one line (colon)
• E711 comparison to None should be if cond is None:
• W291 trailing whitespace
• W293 blank line contains whitespace

All error codes can be found here, everything can be chosen by yourself.

In case you want to modify the list of codes to ignore, edit the ignore_codes list in the pre-commit file.

If you want to select only specific codes to scan for, use the select_codes list.
