Lumen-Lang

A minimal, experimental programming language interpreter framework exploring language design, multi-kernel architectures, and separation of concerns between kernel logic and language semantics.

Quick Start

Requirements

• Git
• RustCore (https://www.rust-lang.org/tools/install)

Installation & Running

git clone https://github.com/ivanshim/lumen-lang.git
cd lumen-lang
cargo build
cargo run examples/lumen/loop.lm

Example Programs

# Lumen (Python-style indentation)
cargo run examples/lumen/fibonacci.lm

# RustCore (Rust-style curly braces)
cargo run examples/rust/demo.rs

# PythonCore (Python-like syntax)
cargo run examples/python/fibonacci.py

Language Features

All supported languages include:

• ✅ Variables and arithmetic expressions
• ✅ Comparison and logical operators
• ✅ If/else conditionals
• ✅ While loops with break/continue
• ✅ Proper operator precedence
• ✅ Lexical scoping

Supported Languages

| Language | File Extension | Style | Status | |----------|---|---|---| | Lumen | .lm | Python-style indentation | ✅ Active | | Rust | .rs | Rust-style curly braces | ✅ Active | | Python | .py | Python-like syntax | ✅ Active |

Development Tracks

Lumen has 4 independent development tracks, each with its own architecture and purpose:

Track 1: Microcode Kernel (src_microcode/kernel/)

• Design: Data-driven, table-based execution engine
• Pipeline: 4-stage (Ingest → Structure → Reduce → Execute)
• Principle: ALL language semantics in declarative schemas, ZERO semantic logic in kernel code
