regex backreferences

[Douglas A. Ruisaard]

None of the links to acquire nor contact Thierry on his site (<https://sunny-tdz.com/livecode/sunnyrex>) work.  They just hang indefinitely... but the web site, itself, appears to be functrional.

Can anyone provide an alternative means to contact this developer?

Thanks for confirming, Jacque and Kaveh. I figured that was the case. I can stop beating my head against it now!

Now for a trip to workaround land!

This is a major shortcoming and I have wanted this for years. Thierry has
filled the gap with his excellent SunnyRex library
<https://sunny-tdz.com/livecode/sunnyrex>. I have used it successfully, I
recommend it, and it works well. He has also supported me well after I
purchased SunnyRex. But it is a proprietary dependency and that is
something at the back of my mind.

It would be great if LiveCode could add this feature. Or perhaps come to an
agreement with Thierry so that we reduce dependencies.

I wish it did, but replaceText doesn't support back references. The
parameters at the end are treated as literals, whether as actual quoted
literals or variables containing a value.

If there isn't a feature request for it, there should be.

Hi all,

Does the replaceText() function allow the use of backreferences to
retain
groupings of text between matches. For example, if I have some text like
this:

<p><span style=‘cruft'>Good stuff here.</span></p>

I want to end up something like this:

<h1>Good stuff here.”</h1>

In BBedit I can search for <p><span style=“cruft”>(.*)</span></p> and
replace it with <h1>\1</h1> and it preserves the run of text designated
by
parentheses.
(I know, I can get more fancy on matching the runs of html tags, but I’m
mainly interested in retaining the text, not in regex madness.)

In LC this does not work:

 put replaceText(myText,"<p><span
 style=“cruft”>(.*)</span></p>”,”<h1>\1</h1>”) into myText

I just end up with <h1>\1</h1>, when I want <h1>Good stuff here.</h1>

Can replaceText even do this?
