I want to highlight trailing space at the end of a line in vim. The following command works:
:match Error /\v\s+\n/
But I'm having trouble mapping this to a key:
nnoremap <leader>w :execute "normal! :match Error " . '/\v\s+\n/' . "\<cr>"
Vim responds with:
E114: Missing quote: "\
E15: Invalid expression: "normal! :match Error " . '/\v\s+\n/' . "\
Update:
Having just seen this: http://vim.wikia.com/wiki/Highlight_unwanted_spaces I've got the mapping working, by just writing:
nnoremap <leader>w :match Error /\v\s+\n/<cr>
Can anyone explaing what the problem is with the original execute normal! ... construct which prevents it from working?
