Klyvos

Klyvos is a programming language project I built as a challenge to myself when I was 17. The goal was to understand how programming languages actually work internally instead of treating compilers and runtimes like black boxes.

The project includes:

• a lexer and parser using ANTLR
• an AST-based compilation pipeline
• a custom bytecode format (.klvb)
• a stack-based virtual machine written in Java

Example Syntax

const a = 10
const b = 5

println(a + b)

Notes

I built most parts from scratch, including the instruction system and execution model. The project was mainly an experiment in language design, parsing, and runtime execution.

It gave me a much better understanding of how interpreters, compilers, and virtual machines work under the hood.
