Expression to copy all text parameters to another comp

[artrfx]

Can I script text source to look at another text in a source comp and match sizing/kerning differences made in the source comp via script? I would need it to match kerning/text size (through character editor) per character.
So I could edit a text freely in one comp, and have those changes all update in some other comp's text I have the expression on?

Yes? No?

Check out 

text.sourceText.style

Most likely only works if all your text is the same format.

Thanks for your response... I have tried everything on that page but this applies source of the style based on one specific letter or overall applied to the entire text. 
For text that need per character style, have that be mirrored, like the word "MacDonalds" in all caps, having smaller and larger letters be matched.

Yea, per character doesn't work unforunately. One of the big painpoints in expressions for text layers over the years, people often resort to multiple stacked text layers and offsetting position, it's not fun.

Basically, no, you can't automatically apply multiple, per-character styles via expression (or script). Once you apply an expression to Source Text all characters are going to get the same styling/formatting as the first character.

Thanks! This was basically the same snag I kept running into, wasnt sure if I was missing anything.
