# L Language
**L** is a minimalist untyped functional programming language inspired by lambda calculus, designed for evaluating mathematical expressions and recursive functions.
## 🚀 Quick Start
### 1. Run the Web Playground
Experience L in a modern, interactive web interface.
```bash
stack run -- -w
```
Open **[http://localhost:3000](http://localhost:3000)** in your browser.
### 2. Run the CLI REPL
Use the interactive command-line interface.
```bash
stack run -- -r
```
## 📚 Documentation
Detailed documentation is available in the `docs/` directory:
- **[Getting Started](docs/getting_started.md)**: Installation, building, and running instructions.
- **[Language Reference](docs/language_reference.md)**: Syntax, built-in functions, and examples.
- **[Architecture Guide](docs/architecture.md)**: Overview of the codebase and project structure.
## 🌟 Key Features
- **Lambda Calculus Core**: First-class functions, recursion, and higher-order functions.
- **Simple Syntax**: Minimalist and easy to learn (similar to Haskell/ML).
- **Interactive Tools**: Built-in CLI REPL and Web Playground with execution tracing.
- **Traceable Execution**: See step-by-step evaluation of your code.
