Hi All,
I need replace all num of a list
I use this:
Code: Select all
function getTextWithoutNumber pText
put "0123456789" into tNum
repeat for each char tReplace in tNum
replace tReplace with "" in pText
end repeat
return pText
end getTextWithoutNumber
but I guess there is a more elegant way.
Best regards
Jean-Marc

Bonjour Jean-Marc,
more elegant, Umm, kind of subjective feeling..
Anyway, here is one *I* feel strongly elegant
Code: Select all
function getTextWithoutNumber pText
return replaceText( pText, "\d+", empty)
end getTextWithoutNumber
HTH,
Thierry

Thierry does this in one line, as usual.
But I think that Jean-Marc, by formulating his handler so that only ten iterations are required to filter any length of text, as opposed to looping through each char in the text itself:
Code: Select all
...
repeat for each char tChar in tText
if tChar is not in "0123456789" then put tChar after tFilteredText...
is already pretty elegant. I only mention this to catch the eye of relatively new users who might appreciate this method, as opposed to that even more "basic" way...

Well, I'm using a pure Livecode build-in function
Code: Select all
...
repeat for each char tChar in tText
if tChar is not in "0123456789" then put tChar after tFilteredText...
is already pretty elegant.
Certainly,
and it's always nice and instructive to show different solutions
and let the reader decide...

Of course you are. And I even use regex, though I need to tread carefully in that arena, where you are adept.
I just want to teach.

Yes, and so do I; a mixture of helping and sharing.
Have a nice sunday,

@Thierry,
Exactly what I have searched
Thanks
@Craig,
Yes LiveCode is a wonderful tool for learn coding
From simple to complex we can try different ways
Best regards
