What is it all about?

XRegExp provides augmented (and extensible) JavaScript regular expressions. You get new modern syntax and flags beyond what browsers support natively. XRegExp is also a regex utility belt with tools to make your client-side grepping and parsing easier, while freeing you from worrying about pesky aspects of JavaScript regexes like cross-browser inconsistencies and manually manipulating lastIndex.

Key Features

• Adds new regex and replacement text syntax, including comprehensive support for named capture. • Adds new regex flags: s, to make dot match all characters; x, for free-spacing and line comments; n, for explicit capture mode; and A, for astral mode (full 21-bit Unicode matching). • Provides a suite of functions that make complex regex processing easier. • Fixes or helps you avoid the most commonly encountered cross-browser inconsistencies in regex behavior and syntax. • Supports addons that add even more new regex syntax, flags, and methods. Offical addons support Unicode, recursive matching, and grammatical patterns.
