Break a line of text in half to the nearest word

[Andrei Popa]

Try this


function breakInTwo(myString) {
var mid = Math.floor(myString.length / 2);
var before = myString.lastIndexOf(" ", mid);
var after = myString.indexOf(" ", mid + 1);

if (before == -1 || (after != -1 && mid - before >= after - mid)) {
mid = after;
} else {
mid = before;
}
return myString.substring(0,mid)+"\n"+myString.substring(mid+1)
}
breakInTwo(text.sourceText)

Wow, this is absolutely brilliant!!!

I’m also running another expression to pull in the font style but I’m not sure if/how I can have them both running:

style.setFont(comp(“00 Color Control”).layer(“Headline Text Font Style”).text.sourceText);

Also, would it by any chance be possible to remove any existing line breaks first?

[Andrei Popa]


function breakInTwo(myString) {
myString = myString.replace(/\r?\n|\r/g, "");
var mid = Math.floor(myString.length / 2);
var before = myString.lastIndexOf(" ", mid);
var after = myString.indexOf(" ", mid + 1);

if (before == -1 || (after != -1 && mid - before >= after - mid)) {
mid = after;
} else {
mid = before;
}
return myString.substring(0, mid) + "\n" + myString.substring(mid + 1);
}
val = breakInTwo(text.sourceText);

style.setFont(comp("00 Color Control").layer("Headline Text Font Style").text.sourceText.style.font).setText(val);

I can’t thank you enough!

Sorry to ask again… instead of removing any existing line breaks instead could it be that if there is an existing line break not to run the expression?

[Andrei Popa]

This were easier if you knew what you wanted from the start :))

You can replace the last “value” with any other piece of expression you want. I say this because maybe you want to use the one with the font.


function breakInTwo(myString) {
var mid = Math.floor(myString.length / 2);
var before = myString.lastIndexOf(" ", mid);
var after = myString.indexOf(" ", mid + 1);

if (before == -1 || (after != -1 && mid - before >= after - mid)) {
mid = after;
} else {
mid = before;
}
return myString.substring(0, mid) + "\n" + myString.substring(mid + 1);
}
val = breakInTwo(text.sourceText);

if (text.sourceText.indexOf("\n") == -1 || text.sourceText.indexOf("\r") == -1) {
style.setFont(comp("00 Color Control").layer("Headline Text Font Style").text.sourceText.style.font).setText(val);
} else {
value;
}

So sorry, I’m completely new to this.
That seems to still add the line break when there is already a linebreak present…

[Andrei Popa]

I was joking, don’t worry, i’m here to help! ?

I made a mistake in the lase expression. Try this one. Again, you can replace “value” with some other expression if you need to.


function breakInTwo(myString) {
var mid = Math.floor(myString.length / 2);
var before = myString.lastIndexOf(" ", mid);
var after = myString.indexOf(" ", mid + 1);

if (before == -1 || (after != -1 && mid - before >= after - mid)) {
mid = after;
} else {
mid = before;
}
return myString.substring(0, mid) + "\n" + myString.substring(mid + 1);
}

if (text.sourceText.indexOf("\n") != -1 || text.sourceText.indexOf("\r") != -1) {
value;
} else {
val = breakInTwo(text.sourceText);
style.setFont(comp("00 Color Control").layer("Headline Text Font Style").text.sourceText.style.font).setText(val);
}

That works a charm!

Would it be easy to put in another statement that if the text length is less than say 20 characters no line break is added?

[Andrei Popa]

function breakInTwo(myString) {
var mid = Math.floor(myString.length / 2);
var before = myString.lastIndexOf(” “, mid);
var after = myString.indexOf(” “, mid + 1);

if (before == -1 || (after != -1 && mid – before >= after – mid)) {
mid = after;
} else {
mid = before;
}
return myString.substring(0, mid) + “\n” + myString.substring(mid + 1);
}

if (text.sourceText.indexOf(“\n”) != -1 || text.sourceText.indexOf(“\r”) != -1 || text.sourceText.length<20) {
value;
} else {
val = breakInTwo(text.sourceText);
style.setFont(comp(“00 Color Control”).layer(“Headline Text Font Style”).text.sourceText.style.font).setText(val);
}
