## Overview
**A general-purpose systems language that's easy to read, fast to run, and keeps your memory safe.**
Olive was built for when you want the speed of a low-level language without the headache of complex syntax. It uses a clean, indentation-based structure and a smart ownership model to provide consistent performance without a garbage collector.
## Why Olive?
- **Clean Syntax**: No braces, no semicolons. Indentation defines the structure, keeping your code readable and consistent.
- **Fearless Safety**: A borrow checker catches memory errors and data races at compile time. No null pointers, no double-frees.
- **Blazing Fast**: Optimized to native code via the Cranelift backend. It's designed to run close to the metal with zero-cost abstractions.
- **Modern Concurrency**: True async/await that's easy to use and extremely efficient.
- **Native Interop**: Interface with C or Rust libraries through a C-compatible ABI with built-in FFI support.
- **Friendly Errors**: When things go wrong, the compiler tells you exactly where and why, with suggestions on how to fix it.
## A Taste of Olive
```python
# A generic function to calculate average
fn average[T: Numeric](numbers: [T]) -> float:
let mut total = 0.0
for n in numbers:
total += float(n)
return total / float(len(numbers))
async fn process_data(data: [int]):
print(f"Processing {len(data)} items...")
let avg = average(data)
print(f"Result: {avg:.2f}")
fn main():
let data = [10, 20, 30, 40, 50]
# Spawning an async task
async:
await process_data(data)
main()
```
## Getting Started
