JSON Templating Engine

The JSON Templating Engine is a user-friendly templating engine designed to streamline the process of generating large numbers of JSON files. It adheres to standard JSON syntax, and files should have the .templ extension.

Example: Creating a Loot Table with All Possible Potions

Below is a real-life example demonstrating how to create a loot table that includes all possible potions using the JSON Templating Engine:

{
  "$template": {
    "pools": [
      {
        "rolls": 1,
        "entries": [
          {
            "$comment": "Iterate over the range of 5 to 42 (inclusive)",
            "{{#5..42}}": {
              "type": "item",
              "name": "minecraft:potion",
              "weight": 1,
              "functions": [
                {
                  "function": "minecraft:set_data",
                  "$comment": "Set the data field to the index value. The '=' sign forces conversion to a number",
                  "data": "{{=value}}"
                }
              ]
            }
          }
        ]
      }
    ]
  }
}

In the JSON example above, we want to create a loot table that includes all possible potions. To achieve this, we repeat the block from the field {{#5..42}} and replace the value variable with a number between 5 and 42 for each iteration.

You can preview the result online in the ‘JSON Templating Engine’ section.
