XRegExp 0.5: JavaScript regex library

XRegExp is a JavaScript library that provides an augmented, cross-browser implementation of regular expressions, including support for additional modifiers and syntax. Several convenience methods and a new, powerful recursive-construct parser that uses regex delimiters are also included.

Here's the feature list:

• Added regex syntax:
  • Comprehensive named capture support.
  • Comment patterns: (?#…).
• Added regex modifiers (flags):
  • s (singleline), to make dot match all characters including newlines.
  • x (extended), for free-spacing and comments.
• Added awesome:
  • Reduced cross-browser inconsistencies.
  • Recursive-construct parser with regex delimiters.
  • An easy way to cache and reuse regex objects.
  • The ability to safely embed literal text in your regex patterns.
  • A method to add modifiers to existing regex objects.
  • Regex call and apply methods, which make generically working with functions and regexes easier.

All of this can be yours for the low, low price of 2.4 KB. :-) Version 0.5 also introduces extensive documentation and code examples. Get it while it's hot! XRegExp: JavaScript regular expression library.
