Question

I want to match something but exclude `\t

in ruby : [^\t] which mean match anything but\t`

what is it’s equivalence in vim ?

Answer 1

In vim’s syntax, you usually have to escape those brackets. But there’s a switch you can use at the beginning of your regex, \v, which turns on “very magic” handling so you don’t.

It’s bad for compatibility to change the default regex syntax, but I prefer not to have to type backslashes all the time. I have these in my .vimrc, which automatically inserts the very-magic switch for me.

" set the "very magic" option in common searches
nnoremap / /\v
vnoremap / /\v
cnoremap s/ s/\v

See :help \v for more examples.
