Installation
------------
-Use [vim-pathogen](https://github.com/tpope/vim-pathogen) if you're not using
-it already. Then, simply put the contents of this repository in your
-`~/.vim/bundle` directory.
+
+Make sure you've installed the
+[flake8](https://pypi.python.org/pypi/flake8/) package.
+
+If you use vim >= 8, install this plugin with:
+```
+mkdir -p ~/.vim/pack/flake8/start/
+cd ~/.vim/pack/flake8/start/
+git clone https://github.com/nvie/vim-flake8.git
+```
+
+Otherwise, install [vim-pathogen](https://github.com/tpope/vim-pathogen)
+if you're not using it already. Then, simply put the
+contents of this repository in your `~/.vim/bundle` directory.
Usage
-----
It shows the errors inside a quickfix window, which will allow your to quickly
jump to the error locations by simply pressing [Enter].
+If any of `g:flake8_show_in_gutter` or `g:flake8_show_in_file` are set to `1`, call:
+
+ call flake8#Flake8UnplaceMarkers()
+
+To remove all markers. No default mapping is provided.
Customization
-------------
another key. It autodetects whether it has been remapped and won't register
the `<F7>` key if so. For example, to remap it to `<F3>` instead, use:
- autocmd FileType python map <buffer> <F3> :call Flake8()<CR>
+ autocmd FileType python map <buffer> <F3> :call flake8#Flake8()<CR>
+
+For flake8 configuration options please consult the following page:
+
+http://flake8.pycqa.org/en/latest/user/configuration.html
+
+To customize the location of your flake8 binary, set `g:flake8_cmd`:
+
+ let g:flake8_cmd="/opt/strangebin/flake8000"
+
+To customize the location of quick fix window, set `g:flake8_quickfix_location`:
+
+ let g:flake8_quickfix_location="topleft"
+
+To customize the height of quick fix window, set `g:flake8_quickfix_height`:
+
+ let g:flake8_quickfix_height=7
+
+To customize whether the quickfix window opens, set `g:flake8_show_quickfix`:
+
+ let g:flake8_show_quickfix=0 " don't show
+ let g:flake8_show_quickfix=1 " show (default)
+
+To customize whether the show signs in the gutter, set `g:flake8_show_in_gutter`:
+
+ let g:flake8_show_in_gutter=0 " don't show (default)
+ let g:flake8_show_in_gutter=1 " show
+
+To customize whether the show marks in the file, set `g:flake8_show_in_file`:
+
+ let g:flake8_show_in_file=0 " don't show (default)
+ let g:flake8_show_in_file=1 " show
+
+To customize the number of marks to show, set `g:flake8_max_markers`:
+
+ let g:flake8_max_markers=500 " (default)
+
+To customize the gutter markers, set any of `flake8_error_marker`, `flake8_warning_marker`,
+`flake8_pyflake_marker`, `flake8_complexity_marker`, `flake8_naming_marker`. Setting one to
+the empty string disables it. Ex.:
+
+ flake8_error_marker='EE' " set error marker to 'EE'
+ flake8_warning_marker='WW' " set warning marker to 'WW'
+ flake8_pyflake_marker='' " disable PyFlakes warnings
+ flake8_complexity_marker='' " disable McCabe complexity warnings
+ flake8_naming_marker='' " disable naming warnings
+
+To customize the colors used for markers, define the highlight groups, `Flake8_Error`,
+`Flake8_Warning`, `Flake8_PyFlake`, `Flake8_Complexity`, `Flake8_Naming`:
+
+ " to use colors defined in the colorscheme
+ highlight link Flake8_Error Error
+ highlight link Flake8_Warning WarningMsg
+ highlight link Flake8_Complexity WarningMsg
+ highlight link Flake8_Naming WarningMsg
+ highlight link Flake8_PyFlake WarningMsg
+To show the error message of the current line in the ruler, call `flake8#ShowError()`:
+
+ " add binding to call the function
+ nnoremap <C-K> :call flake8#Flake8ShowError()<cr>
+
Tips
----
A tip might be to run the Flake8 check every time you write a Python file, to
enable this, add the following line to your `.vimrc` file (thanks
-[Godefroid](http://github.com/gotcha)!):
-
- autocmd BufWritePost *.py call Flake8()
-
-To ignore errors, in your .vimrc:
+[Godefroid](https://github.com/gotcha)!):
- let g:flake8_ignore="E501,W293"
+ autocmd BufWritePost *.py call flake8#Flake8()
This plugin goes well together with the following plugin:
-- [PyUnit](http://github.com/nvie/vim-pyunit) (unit test helper under `<F8>`
+- [PyUnit](https://github.com/nvie/vim-pyunit) (unit test helper under `<F8>`
and `<F9>`)

+
+Max line lengths
+----------------
+
+One particular customization a lot of people like to make is relaxing the
+maximum line length default. This is a config setting that should be set in
+flake8 itself. (vim-flake8 "just" invokes it and deals with showing the output
+in Vim's quickfix window.)
+
+To do so, put the following into your `~/.config/flake8` file:
+
+ [flake8]
+ max-line-length = 120
+
+
+History
+-------
+1.6: Deprecated configuring flake8 options through Vim settings. Instead,
+advise users to use the `~/.config/flake8` config file.
+
+ - Decprecated options:
+ - `g:flake8_builtins`
+ - `g:flake8_ignore`
+ - `g:flake8_max_line_length`
+ - `g:flake8_max_complexity`
+
+ - New options:
+ - `g:flake8_quickfix_height`
+
+1.5: Added markers and the option to don't show the quickfix window, also split
+functions into a autoload file. Added:
+
+ - Options:
+ - `g:flake8_show_quickfix`
+ - `g:flake8_show_in_gutter`
+ - `g:flake8_show_in_file`
+ - `g:flake8_max_markers`
+ - `flake8_error_marker`
+ - `flake8_warning_marker`
+ - `flake8_pyflake_marker`
+ - `flake8_complexity_marker`
+ - `flake8_naming_marker`
+ - Functions:
+ - `flake8#Flake8UnplaceMarkers()`
+ - `flake8#Flake8()`
+ - Highlighting:
+ - `Flake8_Error`
+ - `Flake8_Warning`
+ - `Flake8_Complexity`
+ - `Flake8_Naming`
+ - `Flake8_PyFlake`
+
+1.4: Suppress output to stdout.
+
+1.3: Added the following options:
+
+ - `g:flake8_builtins="_,apply"`
+ - `g:flake8_max_complexity=10`
+
+1.2: Added the following options:
+
+ - `g:flake8_cmd="/opt/strangebin/flake8000"`
+ - `g:flake8_max_line_length=120`
+ - `g:flake8_ignore="E501,W293"`
+
+1.1: Added `g:flake8_ignore` option.
+
