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 jаvascript. 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.

The loss of source codes is a very serious problem for many developers. From my personal experience I can say that it is indeed a terrible misfortune. Imagine you write the program, spend your force, time and money, release compiled program to the customers... But one morning you see that all your sources are gone (it may be your cat, or aliens. Who knows?) You are in panic. What should you do? Tear one's hair? There is no need. Just take the VB Decompiler and simply decompile your project! VB Decompiler restores the source code from the pseudo code (P-Code) as close as possible to the original. So, after some modifications you may get really workable source code.
