Maybe existing style utilities can determine paragraph length globally. As far as I can see, InTools’s style utility doesn’t, but a basic version is not difficult to script. The example below creates a text file Paragraph_count.txt on your desktop with the name of each document followed by a list of stories, each with a list of paragraph index and word count. The file is opened after script finishes.
I said ‘basic’ because, well, it’s basic. It doesn’t do footnotes or tables, it includes stories on master pages, and you get just a raw count. And that’s the reason why general utilities tend not to include what you want: there are endless ways to customise the presentation of the data, so the script you’re after will typically be a custom job.
(function () {
var i, j;
var report;
var stories, par;
var f;
report = [];
for (i = 0; i < app.documents.length; i++) {
report.push (app.documents[i].name);
stories = app.documents[i].stories.everyItem().getElements();
for (j = 0; j < stories.length; j++) {
report.push ('Story ' + stories[j].id);
par = stories[j].paragraphs.everyItem().getElements();
for (k = 0; k < par.length; k++) {
report.push ('Par. ' + k + ':' + par[k].words.length);
}
}
}
f = File ('~/Desktop/Paragraph_count.txt');
f.encoding = 'UTF-8';
f.open('w');
f.write(report.join('\r'));
f.close();
f.execute();
}());
