Simian Programming Language Interpreter

Simian is a lightweight and expressive custom programming language with a simple syntax designed for learning and experimentation. This interpreter, written in Go, demonstrates the implementation of a basic yet fully functional programming environment.

Features

• Dynamic Typing: Support for integers, booleans, and functions.
• Control Structures: Includes conditionals (if/else) and loops.
• Function Definitions: First-class functions with lexical scoping.
• Arithmetic Operations: Support for basic mathematical operations (+, -, *, /).
• Variable Bindings: Flexible variable declarations.
• REPL (Read-Eval-Print Loop): An interactive shell for immediate evaluation.

Getting Started

Run through Docker

1. Run the Docker image:

   docker run --rm -it ashabkhan/interpreter

Installation

1. Clone the repository:

   git clone https://github.com/ashab-k/interpeter_go.git
   cd simian-lang

2. Run the interpreter:

   go run main.go

3. Access the REPL (Read-Eval-Print Loop) for immediate code execution.

Usage

Once inside the REPL, you can execute Simian code directly:

let x = 5 * 3;
x + 2;
if (x > 10) { x - 1 } else { x + 1 };

To exit the REPL, use Ctrl+C or type exit.

Example Programs

Fibonacci Sequence

let fib = fn(n) {
  if (n < 2) {
    n
  } else {
    fib(n - 1) + fib(n - 2);
  }
};

fib(10);

Factorial

let factorial = fn(n) {
  if (n == 0) {
    1
  } else {
    n * factorial(n - 1);
  }
};

factorial(5);
