  AE script to duplicate and rename.

  Posted by Tom Holmes on October 12, 2015 at 11:28 am

  Hey guys,

  Im trying to create my first script for AE.

  I have a comp called ‘1234_client_project_name_mon’… i want to have a script that duplicates it 6 times and replaces ‘mon’ with tue, wed, thu etc so i end up with 7 identical comps called.
  1234_client_project_name_mon, 1234_client_project_name_tue, 1234_client_project_name_wed etc.

  here what i have so far:

  var day = [“MON”,”TUE”,”WED”,”THU”,”FRI”,”SAT”,”SUN”];
  var active = app.project.activeItem; // defines ‘active’ as the active comp
  var compname = active.name; // defines ‘compname’ as the name of the active comp
  var namearray = compname.split(“_”); // defines ‘namearray’ as array of strings between the underscores.
  var suffix = namearray[namearray.length-1]; // defines ‘suffix’ as the string after the last underscore
  var prefix = compname.replace (new RegExp (suffix, “g”),””); //defines ‘prefix’ as the comp name minus the string after last underscore.
  var activeRoot = app.project.activeItem.parentFolder;

  for (var i=1; i<=6; i++) {
  var newname = (prefix+day[i]);
  active.duplicate();
  active.name=newname;
  }

  this seems to kind of work, but i end up with all the comp names ending in ‘2’ except for the original active item which has been renamed to ‘…_SUN’ (without 2)

  Am i going about it the complete wrong way?

  Thanks

  Tom

  I think I’d do it like this:

  
var days = ["tue","wed","thu","fri","sat","sun"];
var myComp = app.project.activeItem;
var myName = myComp.name;
var newComp;

  for (var i = 0; i < days.length; i++){
newComp = myComp.duplicate();
newComp.name = myName.substr(0,myName.length-3) + days[i];
}
