Illustrator 2017 script for creating layers from spot colors in document

[denisc31888652]

Hello, i have script that I use in my workflow everyday but with new Illustrator 2017 I get an error.

The script is trying to find 4 spot color in document (Cut, Crease, Reverse crease and Outside bleed) and put every single color in own layer named as follows:

Spot color "Cut" > layer "Thru-cut"

Spot color "Crease" > layer "Crease"

Spot color "Outside bleed" > layer "Bleed"

Spot color "Reverse crease" > layer "Crease"

Script that I have used in old Illustrator is this:

#target Illustrator
//Apply to myDoc the active document
var myDoc = app.activeDocument;
//define firts caracter and how many layers do you need
var layerIniName =65;
var numberOfLayers=2;

//Create the layers
for(var i=0; i<=numberOfLayers; i++) {
var layerName = String.fromCharCode(layerIniName)
var myLayer = myDoc.layers.add();
myLayer.name = layerName
layerIniName++
} 

// JavaScript Document 
var doc = app.activeDocument; 
// name indexed object 
var layernames = { 
'A':'Bleed / Grafika', 
'B':'Crease', 
'C':'Thru-cut' 
}; 
// loop through all layers 
for (var i = 0; i < doc.layers.length; i++) 
{ 
//Set up Variable to access layer name 
var currentLayer = app.activeDocument.layers; 
if (layernames[currentLayer.name]) 
{ 
  currentLayer.name = layernames[currentLayer.name]; 
} 
} 


var doc = app.activeDocument;
var paths = doc.pathItems;
var destLayer = doc.layers.getByName ("Thru-cut");


for (var g=0; g<paths.length;g++){
    if (paths.strokeColor.typename == "SpotColor" && paths.strokeColor.spot.name == "Cut") {
        paths.move(destLayer, ElementPlacement.PLACEATBEGINNING);
    };
};

var doc = app.activeDocument;
var paths = doc.pathItems;
var destLayer = doc.layers.getByName ("Crease");


for (var g=0; g<paths.length;g++){
    if (paths.strokeColor.typename == "SpotColor" && paths.strokeColor.spot.name == "Crease") {
        paths.move(destLayer, ElementPlacement.PLACEATBEGINNING);
    };
};

var doc = app.activeDocument;
var paths = doc.pathItems;
var destLayer = doc.layers.getByName ("Bleed / Grafika");


for (var g=0; g<paths.length;g++){
    if (paths.strokeColor.typename == "SpotColor" && paths.strokeColor.spot.name == "Outside Bleed") {
        paths.move(destLayer, ElementPlacement.PLACEATBEGINNING);
    };
};

var doc = app.activeDocument;
var paths = doc.pathItems;
var destLayer = doc.layers.getByName ("Crease");


for (var g=0; g<paths.length;g++){
    if (paths.strokeColor.typename == "SpotColor" && paths.strokeColor.spot.name == "Reverse crease") {
        paths.move(destLayer, ElementPlacement.PLACEATBEGINNING);
    };
};

Can anybody help me resolve this script with new Illustrator?

Thanks

Denis

Hi,

Let's try to make things simple.

var main = function(layerCount) {
var doc, layers;
if ( !app.documents.length ) {
alert("This scripts needs an open document !");
return;
}
//The doc
doc = app.activeDocument;
//Adding useful layers
addLayers ( doc );
//Moving items onto specific layers
moveItems ( doc );
}
var moveItems = function ( doc ) {
var items = doc.pageItems, item, n = items.length, sc, tn, sn, 
layers = getLayersDB(doc),
cutLayer = layers['Thru-cut'],
creaseLayer = layers.Crease,
bleedLayer = layers['Bleed / Grafika'];
while ( n-- ) {
item = items;
sc = item.strokeColor;
tn = sc.typename;
if ( tn =="SpotColor" ) {
sn = sc.spot.name;
if ( sn=="Cut") {
item.move(cutLayer, ElementPlacement.PLACEATBEGINNING);
}
else if ( /^(Reverse )?Crease$/i.test( sn ) ){
item.move(creaseLayer, ElementPlacement.PLACEATBEGINNING);
}
else if ( sn=="Outside Bleed") {
item.move(bleedLayer, ElementPlacement.PLACEATBEGINNING);
}
}
}
}
var addLayers = function ( doc ) {
var layers = getLayersDB ( doc );
var layerNames = [
'Bleed / Grafika',
'Crease',
'Thru-cut'
],
name;
while ( name = layerNames.pop() )  !layers[name]  && addLayer ( doc, name );
};
var addLayer = function ( doc, name ) {
doc.layers.add().name = name;
}
var getLayersDB = function ( doc ) {
var db = {}, layers = doc.layers, n = layers.length, layer;
while ( n-- ) {
layer = layers;
db[layer.name] = layer;
}
return db;
}
main();
