Variables

Variables are defined by Vintage and can be used in the following places:

• File & directory names, e.g. data/%[namespace]/function/load.mcfunction.
• Inside of MCFunction files, e.g. execute as @e run say %[id].
• Inside of JSON files, e.g. "key": "%[value]_test".

The format is %[<query>], where <query> must either be a GJSON query or an iterator using <iterator>.<index?>.

The value of variable must be a string, with the exception of special case.

Special case

In JSON files, if a value is "%[<key>]" (with no additional leading or following text), then it can be expanded into any value.

If the key ends with a question mark ?, then it will remove the key in the case that is isn't defined.

📁 Input (Definition file)

// definitions/my_definition.json { "key1": "Hello World!", "key2": { "abc": true } }

📁 Input (Some other file)

{ "example": "%[key2]", "may_be_removed": "%[because_it_is_optional?]" }

📦️ Output

{ "example": { "abc": true } }
