I know this regex divides a text into sentences. Can someone help me understand how?
/(?<!\..)([\?\!\.])\s(?!.\.)/
Portions:
([\?\!\.])\s: split by ending character (.,!,or?) which is followed by a whitespace character (space, tab, newline)(?<!\..)where the characters before this ‘ending character’ arent a.+anything(?!.\.)after the whitespace character any character directly followed by any.isn’t allowed.Those look-ahead (
(?!) & look-behind ((?<!) assertions mainly seem to prevent splitting on (whitespaced?) abbreviations (q. e. d.etc.).
