# Pluto
**Pluto** is an interpreted programming language implemented in Rust. It features a simple syntax, variable declarations, arithmetic expressions, function calls, and more. Pluto is designed for learning and experimentation.
---
## Features
| Variables | `let` keyword for variable declaration |
| Arithmetic Expressions | Supports `+`, `-`, `*`, `/` |
| Floating Point Support | Both integers and floats supported |
| Function Calls | Built-in functions like `print` |
| Simple Syntax | Easy to read and write |
| Extensible | Add your own built-in functions in Rust |
---
## Example
Given the following Pluto code in `test.po`:
```pluto
let x = 5.5;
print(x + 5);
print(x);
```
**Output:**
```
10.5
5.5
```

## Getting Started
### Prerequisites
- Rust (edition 2021 or later)
### Build
```sh
cargo build --release
```
### Run
```sh
cargo run test.po
```
Or, after building:
```sh
./target/release/pluto test.po
```

## Language Syntax
| Variable Declaration | `let x = 10;` | Declare variable `x` |
| Arithmetic | `let y = x * 2 + 3;` | Expressions with `+ - * /` |
| Function Call | `print(y);` | Call built-in function |
| Float Support | `let z = 3.14;` | Floating point numbers |
---
## Built-in Functions
| print | Prints arguments to stdout | `print(x);` |
