YuPcre2 is a library of Delphi components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl, with just a few differences. There are two matching algorithms, the standard Perl and alternative DFA algorithm:

The Perl algorithm is what you are used to from Perl and j@vascript. It is fast and supports the complete pattern syntax. You will likely be using it most of the time.
DFA is a special purpose algorithm. If finds all possible matches and, in particular, it finds the longest. It never backtracks and supports partial matching better, in particular multi-segment matching of very long subject strings.
