Diamond is a lightweight, interpreted programming language designed for simplicity and readability. Built with a Rust-based interpreter, Diamond offers fast execution and a clean syntax, perfect for scripting and exploring programming concepts.

• First-Class Functions: Easily define and use functions.
• Dynamic Typing: No need for type declarations.
• Control Structures: Includes if, while, and more.
• Built-in Functions: Perform common operations like getting array lengths, manipulating collections, and printing output.

diamond supports:

• fn to define functions
• let for variable declarations
• if, else, and while for control flow
• return for function returns

• len(arg): Get the length of a string or array.
• first(arg), last(arg): Access the first or last element of an array.
• rest(arg): Get all but the first element of an array.
• push(array, value): Append an element to an array.
• say(arg): Print values to the console.

1. Clone the repository:

git clone https://github.com/yourusername/diamond.git
cd diamond

2. Build the interpreter and the REPL binaries (requires Rust):

cargo build --release

3. Play with the language using the REPL or run a .dd file using the interpreter:

./target/release/repl

OR

./target/release/diamond examples/fibonacci.dd
