regex backreferences

[Kaveh]

Hi all

I emailed Thierry on 23 Dec and I have had no response. It looks like his last
post
<https://forums.livecode.com/viewtopic.php?f=9&t=36139&p=207519#p207519> on
the Forum was in July 2021.

His software for backreferences <https://sunny-tdz.com/livecode/sunnyrex> works
beautifully. It is closed source and commercial. I purchased it and used it
successfully. He also provided good support.

Precisely because I could not have my stacks dependent on proprietary
software, I stopped using his sunnYrex program and started implementing
backreferences myself. it is not an easy task and I even wonder if an
efficient method is possible using LiveCode scripting.

But I have made a start and if anyone is interested I am happy to
collaborate.

The ideal would be if LiveCode could implement this. The feature request
ticket is here <https://quality.livecode.com/show_bug.cgi?id=21534>.

Regards
Kaveh
