Usage
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:
-https://flake8.readthedocs.org/en/latest/config.html
+http://flake8.pycqa.org/en/latest/user/configuration.html
To customize the location of your flake8 binary, set `g:flake8_cmd`:
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
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](https://github.com/gotcha)!):
- autocmd BufWritePost *.py call Flake8()
+ autocmd BufWritePost *.py call flake8#Flake8()
This plugin goes well together with the following plugin:
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
