rearranging live text
First time poster, long time lurker (and appreciator of the wonders to be found here).
I am looking for help with an expression that will take a line of text of varying length and swapping the last half of the text with the first to create a resulting layer of text.
So the master text layer might say…
“ONCE IN A WHILE I’M THINKING OF YOU”
And the second text layer would say…
“I’M THINKING OF YOU ONCE IN A WHILE”
I have some conceptual grasp of getting lengths, indexing, and splitting into strings, but I’m having trouble getting this effect to work.
Thinking ahead, I would also have to account for an odd number of words, and making sure that there is a properly placed space after swapping the text around.
Any help would be much appreciated.
Thank you.

How does the expression know where to split the text?

Thanks for the quick reply Dan. I would think spaces would work for this purpose.

Maybe something like this:
sp = value.split(" ");
if (sp.length > 1){
a = b = "";
n = Math.floor(sp.length/2);
for (i = 0; i < sp.length; i++){
if (i < n){
b += sp[i] + " ";
}else{
a += sp[i] + " ";
}
}
a+b
}else
value

This worked like magic, Dan. Wait, WAS it magic?
Once this project I’m working on is public, I will share with you what this handiwork was for.
Much appreciated.
