Experimenting with replacing text in a Sketch document

ReplacingText

var replaceValues = function(string, values) {
  var newString = string;

  for (var i=0; i < values.length; i++) {
    var stringToken = "["+(i+1)+"]";
    newString = newString.replace(stringToken, values[i]);
  }

  return newString;
}

var values = [
  ["Cat", "miao"],
  ["Dog", "woof"],
  ["Quokka", "??"]
];

var template = context.selection[0];
var frame = template.frame()

var width = frame.width()
var height = frame.height()

for (var rowId=0; rowId < values.length; rowId++) {
  var rowValues = values[rowId];
  var instance = template.duplicate();

  var instanceFrame = instance.frame()
  instanceFrame.addX((width + 30) * (rowId + 1))

  // change the artboard/layer name
  var newName = replaceValues(instance.name(), rowValues);
  instance.setName(newName);

  var labels = instance.children();

  for (var labelId=0; labelId < labels.length(); labelId++) {
    var label = labels[labelId];

    if (! [label isKindOfClass:[MSTextLayer class]]) {
      continue
    }

    var existingText = label.stringValue()
    var newText = replaceValues(existingText, rowValues);

    label.setStringValue(newText)

    // reset name, so that the displayed string is update
    var name = label.name()
    label.setName(newText)
    label.setName(name)
  }
