Syntax

Refer to this documentation, also see test/ for example files

Example input:

ScoreEntries:
   type: u8 =>
      0: change
      1: remove
   entries: []varint
      scoreboard_id: zigzag64
      objective_name: string
      score: li32
      _: type?
         if remove:
            entry_type: i8 =>
               1: player
               2: entity
               3: fake_player
            _: entry_type?
               if player or entity:
                  entity_unique_id: zigzag64
               if fake_player:
                  custom_name: string

Info

The differences to YAML:

• parent nodes with children can have a value
• keys starting with '!' are ignored in the final output

You can also embed JSON for custom ProtoDef types as usual, for example:

string: ["pstring", {"countType": "i32"}]

Note: the parser only supports this at a root level. To use nested json inside yaml, you can encapsulate a JSON array with a single quote. For example:

SomeType:
   some_string: '["pstring", {"countType": "i32"}]'
