🌿 Willow

by Ghosthx-Code

A Lightweight Open Source Programming Language

Willow is an experimental programming language featuring a custom lexer, parser, and AST system. It is designed to explore language design, compilation, and low-level control with a clean and minimal syntax.

Version 0.0.2

---

🚀 Features

• Custom-built lexer, parser, and AST
• Simple and readable syntax
• Experimental function and type system
• Designed for future compiler/LLVM integration

---

📦 Installation

git clone https://github.com/Ghosthx-Code/willow.git
gcc willow/build/oak.c -o oak
sudo mv /usr/local/bin/
cd willow
make

---

✨ Example

@define <willow>;

func main() ? <- i32 {
    printfl:("Hello, world")?;
}

🧠 Language Notes

• ? → marks execution flow / control points
• <- → defines return types
• : → used for function-style calls and declarations
• ; → terminates statements

---

🛠 Roadmap

• If lexer, parser, ast does not work fix it
• Make lexer, parser, ast faster
• Full expression support (+ - * /)
• Function arguments + returns
• Better type system
• LLVM backend / compiler
• Standard library

---

🚧 Status

⚠️ Willow is in early development. Expect breaking changes and incomplete features.
