The Premise

EXECUTIVE SUMMARY

Chotulang is an ambitious endeavor to create a programming language from the ground up. It focuses on delivering a dynamic, Python-compatible environment that emphasizes clean syntax, functional programming paradigms, and an improved developer experience.

PROBLEM & MOTIVATION

Modern development often involves wrestling with syntactic baggage and opaque error reporting. The primary motivation behind Chotulang was to strip away unnecessary complexity and provide developers with pinpoint accuracy when things go wrong.

By implementing highly specific error reporting and resolving common developer pain points, Chotulang aims to significantly improve the overall Developer Experience (DX).

System Architecture

data_object

Lexical Analyzer

Responsible for precise token conversion and handling complex multi-character operators.

Feature: Token Conversion
Operators: |> , ??, ..

account_tree

Syntax Parser

Generates the Abstract Syntax Tree (AST) and manages intricate sub-expression handling for method chaining.

Core: AST Generation
Logic: Sub-expression Handler

memory

Evaluation Engine

Executes the AST, managing lexical scoping and the sophisticated implementation of closures.

Execution: AST Traversal
Memory: Lexical Scoping & Closures

Conclusion

Chotulang successfully demonstrates a complete, Turing-complete system-level programming logic built from the ground up. It serves as a testament to rigorous architectural planning and a commitment to elegant, functional design principles.
