Insert Line Break every X number of characters

[Thomas Frenkel]

I never responded with the solution to my question. If you want the expression to respect manually input line breaks you need a second loop wrapped around like this:

txt=value;
lineLength=50;
finStr = "";
splt1=txt.split("\r");
for(n = 0; n < splt1.length; n++){
	outStr = "";
	newLine = "";
	splt2 = splt1[n].split(" ");
	for (i = 0; i < splt2.length; i++)
		{
			if ((newLine + " " + splt2[i]).length > lineLength){
			if (outStr != "") outStr += "\r";		
			outStr += newLine;
			newLine = splt2[i];
			}else{
			if (newLine != "") newLine += " ";
			newLine += splt2[i];
			}
			}
			if (newLine != ""){
			if (outStr != "") outStr += "\r";
			outStr += newLine;
		}
	finStr+=outStr+"\r";
}
finStr;

Yeah I got it working in the end with…

m = thisComp.layer("Captions");
n=0;
fs = text.sourceText.style.fontSize * 1000/effect("boxWidth")("Slider");
if (m.marker.numKeys > 0){
  n = m.marker.nearestKey(time).index;
  if (m.marker.key(n).time > time) n--;
}
if (n > 0)
	{text.sourceText.createStyle().setFontSize(fs).setText(m.marker.key(n).comment);
}else{
	text.sourceText.createStyle().setFontSize(fs).setText("");
}

I’m just goofing around making a flexible subs generator.
