Zig Expression Interpreter

This is my personal project for learning the Zig programming language by building a mathematical expression interpreter.

Project Overview

I'm exploring Zig by building a practical expression evaluator with reverse Polish notation (RPN). The goal is to understand Zig's features like comptime, manual memory management, and error handling through hands-on implementation.

Current Features

• Static memory allocation with fixed buffers
• RPN expression evaluation
• Basic arithmetic operations (+, -, *, /)
• Stack-based implementation
• Compile-time checks and error handling

Building and Testing

zig build test

Project Structure

• main.zig - Entry point and tests
• Calculator.zig - Expression evaluator
• stack.zig - Static buffer stack implementation

Plans

1. Extract Lexer (implement regex matching?)
2. Extract Parser (to AST) (Implement Pratt Parser to use traditional infix notation and more operators)
3. Extract Evaluator

Author Notes

I'm learning Zig because it offers the simplicity and control I wanted in a systems programming language. This project represents my hands-on approach to understanding Zig's unique features and design philosophy.
