This is the very basic scripting language that I used in Voxelgarden.
It's not intended to make anything serious. It's very specific use case is to be a very barebones scripting language that exists as a thin layer over C++ code so some behavior can be specified in configuration files instead of hardcoded.
It's also the result of a fit of piqué because I was pretty angry with Minecraft scripting and wanted to prove that I could write a better language in a week. I'm pretty sure I did.
The full code can be found in my GitLab.
