regexp-engine
regexp-engine is a regexp engine written entirely in Ruby that makes it possible to search in text with advanced search patterns. It supports Perl 5 and some Perl 6 syntax and is fairly compatible with Ruby's native regexp engine, passing almost 98% of the Rubicon tests. The implementation is simple and contains no optimizations.

Changes: This release adds UTF-16BE and UTF-16LE support. The parse-tree can be used for debugging Ruby's internal Regexp class.
- 02 Jun 2004 14:01
Changes: Most of the parser has been rewritten in order to deal with multiple encodings. UTF-8 support has been tested and implemented. For full compatibility with Ruby's native Regexp engine, the String class has been extended with: #sub, #gsub, #match, #scan, #split. The syntax has been extended with octal, hex, widehex, and atomic grouping. A problem with word-boundary anchors has been fixed.

Changes: This release added lookbehind positive/negative of variable width. Other engines usually only supports fixed width, so this is a major achievement.

Changes: The allocation model was refactored so that the Context class now has a role of a caretaker (Memento pattern). This has paved the way for more advanced patterns where lookahead is being used inside of repeats. Now 96.66% of the 1560 rubicon tests passes OK. This is an improvement of 0.66% since the last release.
