find all word non matching pattern in vim

Question

I've found the way to do this is using negative - lookahead and / or posistive lookbehind but I don't seem to find how to type it.

I'm trying to highlight all the lines where the word length is not present

I'm writing ( without success ) /length\@!/

What would be the correct way?

@jmort253 Not the same, I'm searching and want to highlight the non matching word. The referred answer hides the non matching lines and highlights the matching one. — OscarRyz, Mar 12 '12 at 00:19

Try /^$\(length$\@!.\)*$/

This is basically ^.*$ where . can't be followed by length.

In perl regex, it'd be ^((?!length).)*$.

(Make sure you have :set hlsearch to actually highlight all the relevant lines).

Mmhh I'm missing something but don't know what : http://i.stack.imgur.com/jG8l0.png – OscarRyz Mar 12 '12 at 00:25
Sorry, the regex has changed - I typo'd a backslash. It's been fixed now. – mathematical.coffee Mar 12 '12 at 00:27
mmmhh almost.. now I neeed to type an empty space to avoid having the `length` word highlighted :-( http://i.stack.imgur.com/j493o.png – OscarRyz Mar 12 '12 at 00:33
OK, adjusted regex one more time. – mathematical.coffee Mar 12 '12 at 00:53
