Pebble is a strongly and statically typed scripting language, written in and embeddable in C#.
The intent with Pebble was to create a scripting language that was easy to use by people who aren't necessarily full-time programmers. For example, game designers. The conventional wisdom is that dynamically typed languages are easier for beginners because they don't require them to write out the types. I vigorously disagree. It may be faster to write code in a dynamically typed language, but I don't it's faster to write correct code. You can't avoid the problems that come with type limits, conversions, etc by ignoring them. Plus, the whole point of type systems is to help you find errors in your code.
Pebble was created for use in Unity games, though there's nothing in it that specifically ties it to Unity.
Windows: There is a Visual Studio 2017 project in the vs folder. OS X: Install Mono, then run buildosx.sh.
Include all of the .cs files in the /src and /src/lib directories. CLI.cs isn't necessary but without the PEBBLECLI preprocessor symbol defined it will do nothing. CLI.cs in general provides a good example of how to use Pebble, but in essence you just create an Engine, register optional libraries, and call RunScript.
Engine engine = new Engine();
List<ParseErrorInst> errors = new List<ParseErrorInst>();
engine.RunScript("Print(\"Hello, world!");", ref errors, false);
In lieu of standard documentation, Pebble instead has examples/tutorial.txt, which is Pebble script file which contains tons of examples of how (almost) every feature in the language works.
