DIPcre is an advanced regular expression engine for Boland Delphi 4/5/6/7. Regular expressions are a very powerfull extension of wildcard (?*) matching and allow to find almost any pattern within any text string or memory buffer.
The implemented regular expression syntax is Perl 5 compatible and provides full substring capturing, case sensitive and insensitive matching, greedy and non-greedy repetition quantifiers, backtracking, assertions and more. DIPcre not only searches, but also formats and replaces text based on regular expressions.
Unicode is supported via UTF-8.
In addition, DIPcre includes two regular expression edits: TDIPcreEdit and TDIPcreComboBox. Both validate user entry against a regular expression pattern and are quite similar to, but more powerfull then Delphi's TMaskEdit.
DIPcre utilizes *.obj files compiled from the PCRE C-library which compile straight into your exe. The library also ships with Borland's C++ Builder and it used in PHP and the Linux KDE, among others. This makes DIPcre the most powerfull regular expression library for Delphi, both freeware and commercial.
DIPcre comes with full Html Help plus a detailed example project to understand, design and test your regular expressions. It is fully functional with no restrictions. Commercial use and Source Code registration is available for a small fee. |
