Best Delphi Regex library

Hello,

I am searching a pure Delphi library with good full-Perl syntax support.

It should:

match groups (both named and numbered)
be able to match, replace, split
support look-ahead and look behind
come with source
be free
support Unicode
be compatible with Delphi 2009

Which library you prefer?

Here is a short list and discussion on the Delphi About.com site. I've heard good things about TPerRegEx, but haven't used it. The only drawback with it (for me) is the external dll.

Bruce -- you can link in the OBJ files and end up with no external DLL. It's very nice.

That is nice. I try to avoid deploying extra DLLs if I can help it.

DIRegEx has worked very well for me, and it doesn't require any external DLLs. However, the source code isn't free, so it may not meet your needs.

Jan Goyvaerts is the guy for Delphi regular expressions.

He has a nice set of classes based on the PCRE libraries that can be compiled into your Delphi applications.

He's the author of RegexBuddy, a popular application built with Delphi.

Nick, is this the one that will be added to D2010?

Gad D Lord 2009-08-16 21:18:46

There won't be a Regular Expressions Library in D2010, sadly. Probably next time around.

Nick Hodges 2009-08-16 22:33:29

TPerlRegEx meets all of Gad's requirements, except that it's not pure Delphi. It's a wrapper around PCRE, which is written in C.
