Break line expression to fit comp width

[Chris Voelz]

Change your text layer from point to paragraph and then set your text box size to what you want. You can also use \r to add a carriage return in your expression.

Hi.

thanks for the reply.

I’m creating the text layer and inserting the text all by script.

I could split at some white space or insert the \r. But one line can have 2 words and 7, then how to know when and where to break the line?

The problem is that I just can see if the line is too long after seeing the screen.

I’d like something similar to the auto-scale using expression but in this case the text size changes by each line and it’s not what I want.

I need some simple way of restricting the textbox to the comp width, and once the text reaches this dimension, it breaks the line and so on.

But I can just figure out a complicated one using a bunch of expressions.

Well,
to create a paragraph text you need just set an “addBoxText”.
The problem is that in the docs (https://ae-scripting.docsforadobe.dev/layers/layercollection/?highlight=addboxtext#layercollection-addboxtext) the “text” parameter is missing, and without it won’t work.

So, to add point text:
myTextLayer = comp.layers.addText(text);

And for paragraph text:

myTextLayer = parentComp.layers.addBoxText([width, height], text);

Hope it helps anyone with the same problem.
