ReplaceText problem

Hi - since the "word" chunk includes punctuation I want to find another way to replace only the word and not the punctation,
I'm trying the replaceText function but it gives me a strange output.
Code: Select all
put replaceText("[Apple].","[Apple]","Orange")
outputs:
[OrangeOrangeOrangeOrangeOrange].
what is happening here?

Hei Sjat,
no idea, but this is surely not what you exspected!?
What about this:
Code: Select all
on mouseUp
put "Apple. Apple, Apple!" into tText
put replaceText(tText,"Apple","Orange")
end mouseUp
-> Orange. Orange, Orange!
Best

Thanks Klaus, I'm using variables.
There is something happening when the text contains square brackets....
I use square brackets in my text as references to be replaced with other words etc.
I found that using the chunk expression "word" it spits back the word AND period/punctuation mark. I need to use "word" because I don't want to replace ALL the words.
like this:
Code: Select all
on mouseup
put "[tomato]" into tMatchword
put field "text" into tText
repeat with tLoop=1 to the number of words in tText
if word tLoop of tText = tMatchword then put random(1000) into word tLoop of tText
end repeat
end mouseup
The problem with this is that the tMatchword will not be found if there is a punctuation mark after a word.

Umm, this is right
your regex contains a character class, which means any character inside the [ ]
will try to match some char in your text.
So, the A matches the A and is replaced by Orange,
then the p matches the p and is replaced by .., and so on.
If I understand what you want, try this one:
Code: Select all
put replaceText("[Apple].","\[Apple]","Orange")

Thierry

Hej Sjat,
ah, I understand.
Sorry, but my example is the only bit of regex I understood until today
There are some Regex pros here in the forum and they will hopefully chime in.

Klaus, thanks anyway
Thierry, Perfect! That worked.
What does the "\" do?

What does the "\" do?
the square brackets have some meanings in a regex;
it's called a character class. If you want to match a square bracket then
you need to escape it, so it is seen as a single char. The trick is you need to
escape only the opening bracket;
the regex engine is smart and then understand what you want
Dos this make sense?

Thierry

@Thierry
Yes, that makes sense, thank you. But now I want to know more about the regex engine
Have any links?
BTW: do you think I should use curly brackets for my reference tags? just to make sure to be safe from future problems, I mean.

Hi to all.
Followinf this regex post, why (Thierry
) the code following doesn't work despite the "\" char in front of the char "°" ?
Code: Select all
put "C'est la ligne n\°:" into laLigne
laLigne return the string "C'est la ligne n\:"
What am I missing ?

Umm, should ask the support
If you want a quote in your string, you have to do that:
Code: Select all
put "C'est la ligne n" & quote & ":" into laLigne
Bon dimanche,

OK Thierry, no problem.
I understood, thanks to you, the use of quotes in a string.
What I notice is that when using the special char "°" which is gotten by <Alt + 0176> it doesn't show in LC6.5.2 on my machine, despite the char "\" in front of it...
Bon dimanche as well.
