[OpenWrt-Devel] Convincing vim on Fedora to highlight 'bad' whitespace

[Daniel Dickinson]

Hi all,

While not strictly an OpenWrt topic, in the interests of helping other 
with the style guidelines, here's a snipped for your $HOME/.vimrc

The following is mostly from John Crispin, with one additional regex 
(for lines beginning with any number of sets of 8 spaces prior to 
non-whitespace text).

Also note that on Fedora vim-minimal is install by default as vi.  If 
you do not set up and alias or similar, when you type vi you get 
vim-minimal (which doesn't have the required functionality) instead of 
vim-enhanced (assuming you've installed it), for which you must use the 
command vim.

[below here goes in $HOME/.vimrc]

highlight link localWhitespaceError Error

highlight link localWhitespaceError Error
autocmd Syntax * syn match localWhitespaceError /\( \{8\}\)\+\ze[^\s]/ 
display
autocmd Syntax * syn match localWhitespaceError /\(\zs\%#\|\s\)\+$/ display
autocmd Syntax * syn match localWhitespaceError / \ze\t/ display

Regards,

Daniel
