Introduction

A lightweight JavaScript-like scripting language running on the JVM, originally designed to add dynamic functionality to .yml configuration files in Minecraft Paper plugins.

Its Abstract Syntax Tree (AST) is built using a custom implementation of the Pratt Parser.

• Native support for Adventure API Component template strings and + operations
• Uses BigDecimal for numeric storage
• Supports array and string slicing syntax
• Supports configuration-friendly function calls like func{arg1="1", arg2="2"}
• Simple lexical scoping mechanism
• Allows registering native Java functions via ScriptObject and MethodHandle
• Includes built-in utility functions for interacting with the Minecraft environment, such as message(msg) and tp_to_player(player_name)

Use Cases

• Deserializing specific objects from configuration
• Allowing users to configure how predefined functions are executed
