A regular expression library for Luau. Adapted from a regex implementation by github user Blockzez (https://github.com/Blockzez).

The Match object resulting from exec has the following fields:

• [1..n] - The array potion of the Match object contains captured groups
• n - The length of the array of resulting captured groups
• index - The index in the original string where the match begins
• input - The original string passed into exec

Flags

The following flags can be provided via the second argument to RegExp.new:
