Configuration

By default python source code is checked with frosted,
pep8 and
mccabe code complexity utility.
The following options can be configured through global variables in .vimrc:

Auto-check file for errors on write:

let g:PyFlakeOnWrite = 1

List of checkers used:

let g:PyFlakeCheckers = 'pep8,mccabe,frosted'

Default maximum complexity for mccabe:

let g:PyFlakeDefaultComplexity=10

List of disabled pep8 warnings and errors:

let g:PyFlakeDisabledMessages = 'E501'

Default aggressiveness for autopep8:

let g:PyFlakeAggressive = 0

Default height of quickfix window:

let g:PyFlakeCWindow = 6 

Whether to place signs or not:

let g:PyFlakeSigns = 1 

When usign signs, this is the first id that will be used to identify the

1. Tweak this if you are using other plugins that also use the sign
   gutter

let g:PyFlakeSignStart = 1

Maximum line length for PyFlakeAuto command

let g:PyFlakeMaxLineLength = 100

Visual-mode key command for PyFlakeAuto

let g:PyFlakeRangeCommand = 'Q'

Force python 3 interface:

let g:PyFlakeForcePyVersion = 3

Commands

Disable/enable automatic checking of current file

:PyFlakeToggle

Run checks for current file

:PyFlake

Auto-fix pep8 errors for current file

:PyFlakeAuto

PyFlakeAuto command by default works with the whole file, but also accepts
line ranges. Select some lines in Python code, then use :'<,'>PyFlakeAuto to
re-format and fix pep8 errors for them. For every Python buffer Visual-mode
shortcut is added to quickly fix selection ('Q' by default). Set global
variable g:PyFlakeRangeCommand in .vimrc to change the key sequence. To
disable visual mode mapping, set this variable to empty string.
