How di I use scripts?

[Steve_Dorsey@adobeforums.com]

I found a great paginating script, but I have no idea how to use it.

Thanks (script below)

myPages = app.documents[0].pages;

// Let's make sure that the pages are a multiple of four
app.documents[0].documentPreferences.allowPageShuffle = false;

if (myPages.length % 4 != 0) {
alert("Document length isn't a multiple of four.");
exit();
}

for (i=0; myPages.length>i; i++) {
origSection = myPages[i].appliedSection;
origNumbering = origSection.pageNumberStyle;
origSection.pageNumberStyle = PageNumberStyle.arabic;
pageName = myPages[i].name;
sectName = origSection.name;
if (sectName != "") {
pageName = pageName.split(sectName)[1];
}
pageNo = Number(pageName);
newSection = app.documents[0].sections.add(undefined, undefined, {pageStart:app.documents[0].pages[i], continueNumbering:false, pageNumberStart:pageNo, pageNumberStyle:origNumbering});
origSection.pageNumberStyle = origNumbering;
}
app.documents[0].documentPreferences.allowPageShuffle = true;

for (i=0; (myPages.length/2)>i; i++){
if (i % 2 == 0) {
app.documents[0].pages[myPages.length - 1].move(LocationOptions.before,app.documents[0].pages[i*2],BindingOptions.leftAlign);
} else {
app.documents[0].pages[myPages.length - 1].move(LocationOptions.after,app.documents[0].pages[i*2],BindingOptions.rightAlign);
}
}

Since this is a javascript script, save it as a plain text file with the extension .js in your scripts directory, which is almost certainly C:\Program Files\Adobe\InDesign CS\Presets\Scripts. Open the Scripps palette (Window->Scripting->Scripts. The filename you saved the script under should be there. Double-click on that filename.

Stu's advice on how to activate a JavaScript script posted like this in the forums is right on.

In the case of this particular script, please also note the advice posted here: Dave Saunders "InDesign won't impose pages!?!" 5/5/04 10:21am </cgi-bin/webx?14@@.3bb3c172/6>

The key points are:

1. Work on a copy of your document.

2. Be sure to activate the Spreads option in the print dialogs when printing (or exporting to PDF) the document that this script generates from your original.
