WattleScript

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.
