Resource expansion

Sometimes, you may wish to use respackopts values inside your text files (for example as model transforms), without switching between a bunch of similar files. For this purpose, respackopts allows replacing text in files via resource expansion.

You can use the expansions block in your .rpo to replace content with a value computed through executing a custom μScript block. Values can be accessed in the script in a the same exact way as in condition objects, as the same language and object representation is used, though the result of a script is a string and not a boolean here.

I should probably point out here that, since the result here is always a string, string concatenation via the || operator is possible and recommended. For example, the following is a valid script: 'Text ' || (someNumber * 15) || someBoolean

Example:

conf.json:

{
  "id": "examplePack",
  "version": 6,
  "capabilities": ["FileFilter", "DirFilter"],
  "conf": {
    "oakFence": {
      "uvLock": true,
      "invertOrientation": false,
      "yFactor": 0
    }
  }
}

oak_fence.json.rpo:

{
  "expansions": {
    "uvlock": "examplePack.oakFence.uvLock",
    "orientation": "!examplePack.oakFence.invertOrientation",
    "y000": "examplePack.oakFence.yFactor + 0",
    "y090": "examplePack.oakFence.yFactor + 90",
    "y180": "examplePack.oakFence.yFactor + 180",
    "y270": "examplePack.oakFence.yFactor + 270"
  }
}

oak_fence.json:

{
  "multipart": [
    {
      "apply": {
        "model": "minecraft:block/oak_fence_post"
      }
    },
    {
      "when": {
        "north": "${orientation}"
      },
      "apply": {
        "model": "minecraft:block/oak_fence_side",
        "y": ${y000},
        "uvlock": ${uvlock}
      }
    },
    {
      "when": {
        "east": "${orientation}"
      },
      "apply": {
        "model": "minecraft:block/oak_fence_side",
        "y": ${y090},
        "uvlock": ${uvlock}
      }
    },
    {
      "when": {
        "south": "${orientation}"
      },
      "apply": {
        "model": "minecraft:block/oak_fence_side",
        "y": ${y180},
        "uvlock": ${uvlock}
      }
    },
    {
      "when": {
        "west": "${orientation}"
      },
      "apply": {
        "model": "minecraft:block/oak_fence_side",
        "y": ${y270},
        "uvlock": ${uvlock}
      }
    }
  ]
}

Explanation

The expansions block contains a key ("uvlock") and a script, which is executed when the file is loaded. All instances of the key (formatted as ${name} -> ${lights} in this example) will be replaced by the result of the script. Make sure to only use this feature on text files as unexpected results my occur otherwise
