# Tree Notation: an antifragile program notation

## TL;DR

Tree Notation introduces a universal, simple syntax enabling the creation of new programming languages called Tree Languages, which are represented as geometric trees, offering advantages over traditional languages.

## Contribution

The paper proposes Tree Notation as a universal syntax and introduces Tree Languages, a new family of 2D programming languages based on geometric trees.

## Key findings

- Tree Notation simplifies language design.
- Tree Languages are written as geometric trees.
- Advantages over traditional programming languages.

## Abstract

This paper presents Tree Notation, a new simple, universal syntax. Language designers can invent new programming languages, called Tree Languages, on top of Tree Notation. Tree Languages have a number of advantages over traditional programming languages. We include a Visual Abstract to succinctly display the problem and discovery. Then we describe the problem--the BNF to abstract syntax tree (AST) parse step--and introduce the novel solution we discovered: a new family of 2D programming languages that are written directly as geometric trees.
