Hi Thierry,
OK, well, cool But can you help me understand?
Do you mean if I put this in the message box, making the replacements you
suggest:
put replaceText(abcd,(ab)(cd),\2\1)
I should get:
cdab
Because I get:
\2\1
What am I missing?

You can use back references in the *pattern matching text*,
but not in the replacement text.
Here is one working:
put replaceText( IILLoovveeRReeggeexx, (.)(?!\1), empty )
Not sure everybody will agree with the result :)

What system and LC version do you have?
Are you sure the copy/paste didn't spoil the original regex
or what else could
Agree - matchText and matchChunk would both benefit from the ability to
specify an array to fill with matches - we don't always know exactly how
many will appear ..

Yes, but just having a more complete implementation of PCRE regex would make a
big difference.
For example, LC's regex does not include back references.
Having the ability to use (PCRE compliant) back references would, I believe, in

I have very occasionally tried regex and can see that it is very powerful, but
to me it's also extremely opaque and I've never climbed far up the rather steep
learning curve. Partly this is because I've found that essentially all of the
stuff I would need regex for is do-able in native LC,
That is nice to know!
I was thinking I would speed up the
longer text processing. You just did
me a favor and save me a lot of time
plus made it easier and faster by not
using regex for text processing.
I still appreciate the info others gave
because I know I will use regex from
time to time.
Regex is GREAT!
I use it a LOT.
Anyone need any help to grasp how it works ?

I was interested in using a if then replace combination
but it seems it might be better done in LiveCode using
repeat for each. If the speed is not considerably faster
with regex it is not worth the trouble. The ability to read
my code like I am used to is more important than a small
increase in
