Hava Programming Language

Hava is a simple interpreted programming language written in Python.
The goal of this project is to explore how programming languages are designed and executed, while providing a clean and intuitive syntax in Turkish.

Motivation

I built Hava to understand how programming languages work internally — not just how to use them.
This project focuses on concepts like parsing, execution flow, and language design.

Technical Overview

Hava consists of three main components:

• Lexer: Tokenizes input using defined language rules
• Parser: Builds structured instructions based on grammar
• Interpreter: Executes instructions using a custom runtime environment

The interpreter evaluates code dynamically by walking through the parsed structure and executing operations step by step.

Features

• Simple and readable syntax (Turkish-based)
• Variables and assignments
• Arithmetic operations (+, -, *, /)
• Conditional statements (if / else)
• Loops
• Function definitions and calls
• Interpreter-based execution

Example Code

Hava > fonksiyon test1():: hava_isim = "hava" :
Hava > test1():
Hava > yaz(hava_isim):

Output:

hava

Running the Project

Run the interpreter with:

python run-interpreter.py

Then write your code in the interactive console.

Notes

• This project is in beta and still under development
• Currently interpreter-based (no compiler yet)
• Designed as a learning-focused project

Learning Outcome

Through this project, I gained hands-on experience with:

• how interpreters execute code
• structuring a custom programming language
• designing syntax and execution logic

This project reflects my interest in understanding programming beyond surface-level coding.
