Same idea. I replace  with a character that would not 
be found in any text string. Your version will work as long as there are no 
tabs already in your text.

Thanks Peter, none that I can see although I would probably write:

put quote & "v" & quote & ":" into tempDelim -- i.e. a 4 char delimiter with
embedded quotes
replace tempDelim with tab in tString
set the itemdelimiter to tab

Same idea though and much easier than fussing with replacetext and regular
expressions. I probably didn't think this would work because of the embedded
quotes.

delimiters have to be single characters, I believe.  Not tested but I think
the idea failed on me once.

Re: matchChunk question

Any reason not to just use

put numtochar(8) into tempDelim
replace <4-char-sequence> with tempDelim in tString
set the itemdelimiter to tempDelim

?

Re: matchChunk question

[Mark Smith]

Thanks, worked perfectly. changing the expression to "(\" & quote & "v" & "\"
& quote & ":)" resulted in true, 422, 425 in the output. What I am
attempting to do is define a rather complicated item delimiter, in this case
made up of the 4 char sequence "v":  If I can define where this occurs I can
break the input up into chunks. 

Best,

-- Mark

Hi Mark,

You need to put the part of the regex that you want to know the start and end 
position of inside parantheses. In your case, this seems to be the entire regex.

matchChunk question

[Mark Smith]

Hi, shouldn't the following place the start position and end position of the
regular expression found in the input field into the output field?


on mouseUp
   local startpos, endpos
   put fld"input" into tinput
   put "\" & quote & "v" & "\" & quote & ":" into tregularexpression 
   put matchchunk(tinput, tregularexpression, startpos, endpos) into
fld"output"
   put ", " & startpos & ", " & endpos after fld"output"
end mouseUp


What I am getting in output is: true, ,

With no start and end positions. Anyone see the error of my ways? Thanks

-- Mark

PS lc 5.0.2, on a Mac
