About EGG

When I started my coding journey, I was always curious about how programming languages actually work. It felt like magic — how a few lines of code could be executed by a computer.

One day, when I had very little programming knowledge and only knew the basics of Python, I tried to create my own programming language. At that time, it was a simple program that could take input and produce output. I got stuck when I tried to make it more complex and add more features. That was when I realized that this was not the proper way to build a programming language.

You can check that early attempt here:

For this version, I studied how programming languages actually work. It was not an easy journey because there were not many proper resources available about this topic. However, I kept learning and managed to build:

• Lexer
• Parser
• AST (Abstract Syntax Tree)
• Interpreter architecture

During this process, I also learned new DSA concepts. These were new to me because, on 1/7/26, I had not started studying data structures and algorithms seriously yet.

I learned concepts like:

• Trees
• Binary trees
• Tree traversal
• Recursive structures

and implemented those ideas while building the parser.

The algorithms required to build a parser looked extremely complex before I started. I never thought I would be able to understand them, but eventually, I did.

Features

EGG currently supports:

• Variables
• Functions
• If statements
• For loops
• While loops
• Lists
• Dictionaries
• Basic programming language features

Why EGG?

EGG was not created to compete with large programming languages.

The goal of EGG is to explore, learn, and share the process of creating a programming language.

EGG is a project focused on understanding how programming languages work internally and experimenting with language design.

Built With

• Python
• Lexer
• Parser
• AST
• Interpreter

Because EGG is built with Python, it may not be the fastest programming language. However, it provides a simple way to learn how interpreters and programming languages work internally.

Example

var name = "World"

fun greet(person) {
    show("Hello " + person)
}

greet(name)

Output:

Hello World

Future Plans

Possible future improvements:

• Add a module import system
• Improve error messages
• Create a standard library
• Improve performance
• Add more built-in functions
