RegexBuddy is your perfect companion for working with regular expressions. Easily create regular expressions that match exactly what you want. Clearly understand complex regexes written by others. Quickly test any regex on sample strings and files, preventing mistakes on actual data. Debug without guesswork by stepping through the actual matching process. Use the regex with source code snippets automatically adjusted to the particulars of your programming language. Collect and document libraries of regular expressions for future reuse. GREP (search-and-replace) through files and folders. Integrate RegexBuddy with your favorite searching and editing tools for instant access.

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.

DIFileFinder is collection of Delphi components (Embarcadero / CodeGear, Borland) to search the file system for files and or folders matching (or not matching!) particular attributes and / or name patterns. Pattern syntax includes standard wildcards as well as full Perl compatible regular expressions. DIFileFinder supports inclusion as well as exclusion filters.
