Setting up multiple highlight rules in vim

Question

I am trying to set up rules to highlight both trailing whitespace and lines which are over a certain length by adding this to my .vimrc:

highlight ExtraWhitespace ctermbg=lightgray guibg=lightgray
match ExtraWhitespace /\s\+$/

highlight OverLength ctermbg=lightgray guibg=lightgray
match OverLength /\%>80v.\+/

However, it only seems to pick up whichever is last. I can't find a way to get them to both work simultaneously.

Answer 1

One way:

highlight EWOL ctermbg=lightgray ctermfg=black guibg=lightgray guifg=black
match EWOL /\%>20v.\+\|\s\+$/

Another:

highlight ExtraWhitespace ctermbg=lightgray ctermfg=black guibg=lightgray guifg=black
match ExtraWhitespace /\s\+$/

highlight OverLength ctermbg=lightgray ctermfg=black guibg=lightgray guifg=black
2match OverLength /\%>80v.\+/

Also available: 3match. Up to three matches can be active at a time. Or you can use matchadd() to create matches without limit to the quantity.
