WattleScript is a scripting engine written in C# for runtimes supporting .NET Standard 2.0 and newer. (.NET 4.7.2+, .NET Core 3.1+). It is a dual-language environment, providing support for Lua 5.2 code as well as its own language, Wattle.

Using WattleScript is as easy as:

var script = new Script();
script.DoString("print('Hello World!')");

WattleScript is based off the tried and tested MoonSharp project, inheriting its VM design and test suite. The design focuses on easy and fast interop with .NET objects and functions.

• Wattle scripting language.
• Lua mode 99% compatible with Lua 5.2, differences documented here.
• Easily configured sandbox for safe execution of untrusted scripts.
• Minimal garbage generation at runtime
• No external dependencies
• Easy and performant interop with CLR objects, with runtime code generation where supported
• Source Generator for AOT interop.
• Support for awaiting on returned values
• Supports dumping/loading bytecode
• Support for the complete Lua standard library with very few exceptions (mostly located in the debug module).
• json module for loading json into tables safely at runtime.
