RegexKit is an Objective-C framework for regular expressions using the PCRE library for Mac OS X Cocoa and GNUstep. It includes an extensive collection of category additions for the NSArray, NSDictionary, NSSet, and NSString Foundation objects. License: BSD License (revised) Changes: This release adds many improvements in the handling of Unicode strings. The NSString additions and RKEnumerator class now calculate character indexes and NSRange values the same way the Foundation NSString class does for all string encodings. Perl style u, l, U, L, and E escape sequences for case conversions were added, along with digit for capture subpattern references in replacement reference strings.
