ASTN (Abstract Syntax Tree Notation)

ASTN is designed with the ambition to make editing data files a pleasure. Proper and thourough error reporting. Syntax highlighting. Code completion. All the things you are accustomed to when writing code for a programming language. Without having to develop a language. Write (or find) a schema and you're good to go.

ASTN is a human-editable data format designed to represent abstract syntax trees in a clear, concise, and structured way. It extends JSON’s capabilities by introducing additional notation features to better express complex data structures. ASTN is a superset of JSON, meaning that every JSON file is a valid ASTN file. ASTN files can easily be converted back to JSON files
