You can split the text at linebreaks and then apply dan’s processing to each of the parts separately:

————

txt = thisComp.layer("Source Text").text.sourceText;

n = thisComp.layer("Controls").effect("Text width")("Slider");

function breakToGivenLength(txt,n){

var outStr = "";

var newLine = ""

var splt = txt.split(" ")

for (var i = 0; i < splt.length; i++){

if ((newLine + " " + splt[i]).length > n){

if (outStr != "") outStr += "\r";

outStr += newLine;

newLine = splt[i];

}else{

if (newLine != "") newLine += " ";

newLine += splt[i];

}

if (newLine != ""){

if (outStr != "") outStr += "\r";

outStr += newLine;

}

return outStr;

}

lines = txt.split(/|\r|\n|\x03/);

for(var i=0; i< lines.length; i++){

lines[i]=breakToGivenLength(lines[i],n);

}

lines.join("\n");

————

Note that this still does not deal properly at tabs, for example (it only breaks at simple line breaks but not at tabs).

I found this expression from Dan Ebberts, and it works beautifully until the
source text has line breaks.
After the line breaks, the first lines get shorter. It seems to add the
characters from the line above the break to the character count. See this

Is there a way to make this code aware of line breaks too, so that it just
keeps the line breaks from the source and starts on a new line with the
correct length?

The goal is that the user should just copy-paste text from a word document
or similar, into a field - and it should just work.

/jarle

txt = thisComp.layer("Source Text").text.sourceText;
n = thisComp.layer("Controls").effect("Text width")("Slider");
outStr = "";
newLine = ""
splt = txt.split(" ")
for (i = 0; i < splt.length; i++){
if ((newLine + " " + splt[i]).length > n){
   if (outStr != "") outStr += "\r";
   outStr += newLine;
   newLine = splt[i];
}else{
   if (newLine != "") newLine += " ";
   newLine += splt[i];
}
}
if (newLine != ""){
if (outStr != "") outStr += "\r";
outStr += newLine;
}
outStr;
