Making all paths into a group without selection

Question

I'm working on a script that will take every pathItem in a document and put it into a group (all pathItems in the document are groupless upon opening it, so there won't be other groups already in the document).
I have a script that creates a group, then puts the highest placed pathItem into the group. I just can't figure out how to have to grab all pathitems in the document, or loop this one action until everything is in a single group. Also the kicker is, as the title suggests this script has to work without selecting anything by hand first (in other words having to click something to select it). Now if there's was a way to select everything with a script that would be awesome.
Here's what I have so far:
#target Illustrator
//based on script from Carlos Canto
var doc = app.activeDocument
if ( app.documents.length > 0 ) {
doc = app.activeDocument;
newGroupItem = doc.activeLayer.groupItems.add();
var gi = doc.groupItems[0]; // the topmost existing group
var all = doc.pathItems[0]; // all paths in document
all.move (gi, ElementPlacement.PLACEATBEGINNING); // move selected path inside the group
all.evenodd = true; // necessary to determine "insideness" or to make holes.
I also have this that I found here on the forum
#target Illustrator
// GroupFromSel.jsx
// regards pixxxelschubser
if ( app.documents.length > 0 && app.activeDocument.selection.length > 0) {
    var aDoc = app.activeDocument;
    var Sel = aDoc.selection;
    var GroupFromSel = aDoc.groupItems.add();
    for ( i = Sel.length-1; i >= 0; i--) {
        Sel[i].moveToBeginning( GroupFromSel )
But saddly it requires selecting so two scripts, two possible solutions. I'm just working on both until I can get one to work.
Any ideas?

Answer 1

var all = doc.pathItems[0]; // all paths in document
that's only the top most pathItem, change that to
var all = doc.pathItems; // all paths in document
...and loop thru "all" and move each inside your group
#target Illustrator
//based on script from Carlos Canto
if ( app.documents.length > 0 ) {
    doc = app.activeDocument;
    var gi = doc.activeLayer.groupItems.add();
    var all = doc.pathItems; // all paths in document
    for (i=0; i<all.length; i++) {
        eachPath = all[i];
        eachPath.move (gi, ElementPlacement.PLACEATBEGINNING); // move all pathItems inside the group
else
    alert('no documents to process');
for this set up we will run into trouble if you have other groups with pathItems
