Is there a script for fixing 'one word on a line at end of paragraph'?

Hi,

Peter Kahrel, in GREP in InDesign CS3 (p. 37), to "avoid signle-word last lines" suggest this regex : \s(?=[-\w[:punct:]]+$) in Find what. ~S in Change to

One of the difficulties of fully implementing this by script is that judgment is required. Sometimes, the best result is a single word at the end of a paragraph.

Back in CS days, I wrote about an approach to this, here:

http://www.pdsassoc.com/index.php?Nav=tipssub&Ban=DeruntingParagraphs&Info=tipsCS/DeruntingParagraphs/index.html

I see you're using CS2. That rules out an approach that I was thinking might work involving GREP styles in CS4. Set up a style that looks for at least some fairly large number of characters at the start of a paragraph and then apply No Break to the last n characters, where n is say 15.

Consider: A paragraph that ends with

is it.

Another that ends with

serendipity.

Which of these needs attention? Perhaps neither!

I assume that one text frame is selected. I am on CS3 and it is not properly tested.

var myDoc = app.activeDocument;
var pars = myDoc.selection[0].paragraphs;
for (i = 0; i < pars.length; i++) {
    var par = pars;
    var lastLine = par.lines[-1];
    if (lastLine.words.length < 2) {
        var aWord = par.words[-2];
        var aSpace =  aWord.characters.previousItem(aWord.characters[0]);
        aSpace.contents = "\n";
    }
}

alert("Done");

Alternatively, to replace spaces with nonbreaking spaces you can use the following script:

var myDoc = app.activeDocument;
var pars = myDoc.selection[0].paragraphs;
for (i = 0; i < pars.length; i++) {
    var par = pars;
    var lastLine = par.lines[-1];
    if (lastLine.words.length < 2) {
        par.words[-2].characters.previousItem(par.words[-2].characters[0]).contents = SpecialCharacters.NONBREAKING_SPACE;
        par.words[-1].characters.previousItem(par.words[-1].characters[0]).contents = SpecialCharacters.NONBREAKING_SPACE;
    }
}

alert("Done");

But hyphenate parameter for the paragraphs should be off in this case.
