Hi Shalu,
Here is a quick one for a start:
Code: Select all
put "xxx, zzz, usa-uk,usa--uk,usa---uk,zzz" into T
put replaceText( T, "usa-+uk", "USA_UK" )
You might find interesting to check in the dictionary:
replaceText(), matchChunk() and matchText().
They all works with regular expressions (regex)
Good luck,
Thierry

repeat for each word tLine in sha
put matchtext(tLine, "(\w\-\-\w)") into ssa
if ssa is true then
answer tLine

Hi shalu,
beginner or not, do NOT open two threads for the same problem!
I merged these two threads!
Best

Hi.
Regex is the basis for the power behind replaceText(), matchChunk() and matchText(), as Thierry mentioned. He is our regex guru.
But am I missing your question? Did you simply want to replace all instances of words that contain "-" with another character? Or to eliminate that hyphen from the text entirely? If so. why not just:
Code: Select all
put the text of fld "SSS" into sha
replace "-" with "_" in sha
--or
replace "-" with empty in sha
That sort of thing.

If you're using LiveCode 7 try the "trueWord" chunk type rather than "word". The "word" chunk type uses the old-style rules, maintained in v7 for backward compatibility. But with v7's inclusion of the comprehensive Unicode libraries for smarter parsing, the "trueWord" chunk type allows us to to accommodate more natural-language expressions.
For example, if you put this in a field:
...and then put this in a button:
Code: Select all
on mouseUp
put the number of words of fld 1 \
&cr& the number of trueWords of fld 1
end mouseUp
...you'll get:
2
5

I think what shalu wants to do is put the hyphenated words into a different field, not sure if they need to be deleted from the original field or not.
Is that correct shalu?

If what Pete is saying is true, then the problem goes away. Put this into a button script, with field 1 the field of interest, and a fld 2 to hold the extracted data:
Code: Select all
on mouseUp
set the itemdel to "-"
get fld 1
repeat with y = 1 to the number of items of it
put the last word of item y of it & "-" & the first word of item y + 1 of it & return after temp
end repeat
put temp into fld 2
end mouseUp
But I suspect there is more to this...
