ReplaceText problem

[Sjatplat]

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!

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")

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.

The Regex pro was a tad faster than me

[Sjatplat]

Klaus, thanks anyway

Thierry, Perfect! That worked.

What does the "\" do?

Thierry, Perfect! That worked.

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

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 ?

Followinf this regex post, why (Thierry )

Désolé Monsieur,
I'm an expert only on cheese and some regex

why 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,

Thierry

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.
