RegEx match single character that is not follow by a character

Question

I have a Regex that is almost what I need. I am sure this is a repeat of a repeat however I can't find the answer I am looking for.

Regex I need is an expression that will match a parenthesis that is not followed by a space, however I only want it to match the parenthesis.

(\([^\s])

This will match all parenthesis that are not followed by a space, however it matches the character that is directly after the parenthesis as well. How do I only get a match for the parenthesis?

Answer 1

Use zero width assertion lookahead

\((?=\S)

or

\((?=[^\s])
