Scripting stroke alignment (JSX)

[GeorgeHunt88]

In the Illustrator JavaScript reference book (2017) there's no documented method of changing the stroke alignment of a pathItem that I can see.

I have a set of dynamically created rounded rectangles in a document which all require a stroke to be aligned to the inside of the path. The only other option I can think of is to calculate a new position by subtracting the stroke width from the pathItem width to get a new position for the pathItem but this seems so fiddly to get right.

There must be a way to set this option via scripting? 

Code so far:

      var doc = app.activeDocument;
      var pageItems = doc.pageItems;
      var artLayer = doc.layers.getByName('newFrames');
      
      for(var i = 0; i < pageItems.length; i++)
      {
            if(pageItems[i].name.match("linkedFrame"))
            {
                  var top = pageItems[i].position[1];
                  var left = pageItems[i].position[0];
                  
                  var border = artLayer.pathItems.roundedRectangle
                  (
                        top,       /* y */
                        left,       /* x */
                        new UnitValue(527, 'mm').as('pt'), 
                        new UnitValue(127, 'mm').as('pt'), 
                        new UnitValue(10, 'mm').as('pt'), 
                        new UnitValue(10, 'mm').as('pt') 
                  );
                  
                  var black = new RGBColor();
                  black.red = 255;
                  black.green = 0;
                  black.blue = 0;
                  
                  border.filled = false;
                  border.stroked = true;
                  border.strokeWidth = new UnitValue(2, 'mm').as('pt');
                  border.strokeColor = black;
            }
      }

I'd never needed to do this before, and I'm surprised it doesn't show as a PathItem property like all the other stroke options too. One way to get around this, though it may be complete overkill and someone might come in and give a much better solution, is to dynamically create an Action which you load, execute, then unload when needed:

function setStrokeAlignToInside() {
  if ((app.documents.length = 0)) {
    return;
  }
  var ActionString = [
    "/version 3",
    "/name [ 4",
    "	74657374",
    "]",
    "/isOpen 1",
    "/actionCount 1",
    "/action-1 {",

    "			/key 1836344690",

    "			]",
    "			/value 0",
    "		}",
    "		/parameter-5 {",
    "			/key 1684825454",
    "			/showInPalette -1",
    "			/type (integer)",
    "			/value 0",
    "		}",

    "			/value 1",
    "		}",
    "	}",
    "}"
  ].join("\n");
  createAction(ActionString);
  var ActionString = null;
  app.doScript("SetStroke", "test", false);
  app.unloadAction("test", "");
  function createAction(str) {
    var f = new File("~/ScriptAction.aia");
    f.open("w");
    f.write(str);
    f.close();
    app.loadAction(f);
    f.remove();
  }
}

We can set the Stroke alignment within an Action, but one problem is that we don't set only the alignment -- we also set the width, dashes, etc. You can record any Action, save it, open the .aia file in a text editor, and replace the ActionString variable above with it's contents to dynamically run it within a script without needing the user to have this action.

For the above to work, you'd likely want to clear you app.selection at the beginning of the loop, then set each PathItem.selected to true, run this action just after the stroked = true, then do the styling, and PathItem.selected = false to remove it from the selection so future actions don't affect it.
