TySON
TypeScript as a Configuration Language. TySON stands for TypeScript
...You can think of TySON as JSON + comments + types + basic logic using TypeScript syntax. TySON files use the .tson extension. The goal is to make it possible for all major programming languages to read configurations written in TypeScript using native libraries. That is, a go program should be able to read TySON using a go library, a rust program should be able to read TySON using a rust library, and so on. Our first implementation is written in pure go, and a rust implementation will follow.
