Adding Numbered Line to a Numbered List and Renumbering List

[montymay]

Hello

If you have a list of numbered lines in a field, numbered 1 through x, and you want to add numbered line i, where i =< x, what would be the method for renumbering the list? For example, you want to add the line "3) Oranges" to the following field:

1) Apples
2) Pears
3) Peaches
4) Cherries

so that it becomes:

1) Apples
2) Pears
3) Oranges
4) Peaches
5) Cherries

Thank you for your replies.

Wouldn't something like this work?

Code: Select all

repeat with x to the number of lines of myVar 
// I am guessing the cherries etc. are in a var or array...
	put line x & "your text" & cr after field "Field Name"
end repeat

Hi.

Will pseudoCode do?

Code: Select all

on mouseUp
   put yourData into temp
   put 3 into insertionLine -- you need to extract this number from your new line
   put return & "3) Oranges" after line (insertionLine - 1) of temp 
   
   repeat with y = (insertionLine + 1) to the number of lines of temp
     add 1 to the number at the beginning of line y of temp --very pseudo
   end repeat
   put temp into yourData
end mouseUp

Can you take it from here? If not, write back and I will give the whole thing, or someone will.

I have a handler in a library that I wrote about 30 years ago in HC. I use it everywhere:

Code: Select all

function onlyNumber tText
   repeat for each char tChar in tText
      if tChar is in ".0123456789" then put tChar after temp
   end repeat
   return temp
end onlyNumber

My opinion, this is faster:

from:

Code: Select all

set the htmlText of field 1 to "<ol><li>apples</li><li>Pears</li><li>Peaches</li><li>Cherries</li></ol>"

to

Code: Select all

set the htmlText of field 1 to "<ol><li>apples</li><li>Pears</li><li>Oranges</li><li>Peaches</li><li>Cherries</li></ol>"

@Craig, wouldn't "is a number" be faster? There's also "is an integer" and some others.
