Regex Tester
Test regular expressions with live highlighting and capture groups. No uploads.
How does the regex tester work?
Enter a pattern, toggle the g, i,
m, and s flags, and paste in text to test
against it. Matches are highlighted inline as you type, with a running
match count and a breakdown of every match's capture groups below.
Invalid patterns show a clear error message instead of failing silently.
Everything runs on JavaScript's native RegExp engine in your
browser — your text and pattern are never sent anywhere.

ZeldaEiji Aonuma has said two entire dungeons cut from the original Wind Waker were reworked and reused piecemeal in later Zelda titles, which is why they couldn't simply be restored for the Wii U remaster.
