Examples

Example 1: Iterate over an array

Goal: Show a message for each element in the array.

{
  "type": "forEach",
  "params": {
    "path": "theList",
    "leadingDelimiter": "{:",
    "trailingDelimiter": ":}",
    "actions": [
      {
        "type": "if",
        "params": {
          "condition": {
            "mode": "equal",
            "left": "{:index:}",
            "right": "0"
          },
          "then": [
            {
              "type": "showMessage",
              "params": {
                "text": "first: {:element.text:} of {:count:}"
              }
            }
          ],
          "else": [
            {

              "params": {
                "text": "second: {:element.text:} of {:count:}",
                "asToast": true

            }
          ]
        }
      }
    ]
  }

Example 2: Iterate over an object

Goal: Show a message for each element in the object.

    "trailingDelimiter": ":}",
    "actions": [

        "params": {
          "condition": {
