| 1 | +# SystemScript Language Overview |
| 2 | + |
| 3 | +SystemScript is a multi-paradigm systems programming language designed for complete hardware and software control. The language provides direct hardware manipulation capabilities alongside high-level abstractions, enabling development across the entire computing stack. |
| 4 | + |
| 5 | +## Language Characteristics |
| 6 | + |
| 7 | +### Design Philosophy |
| 8 | + |
| 9 | +SystemScript bridges the gap between low-level system programming and high-level application development through: |
| 10 | + |
| 11 | +- C-like syntax with extended capabilities |
| 12 | +- Recursively enumerable parsing system |
| 13 | +- Optional type safety with explicit unsafe operations |
| 14 | +- Zero-cost abstractions |
| 15 | +- Direct hardware access primitives |
| 16 | + |
| 17 | +### Target Use Cases |
| 18 | + |
| 19 | +- Operating system kernel development |
| 20 | +- Device driver implementation |
| 21 | +- Network protocol development |
| 22 | +- Security research and vulnerability analysis |
| 23 | +- Web application development |
| 24 | +- Embedded systems programming |
| 25 | +- High-performance computing |
| 26 | + |
| 27 | +## Core Features |
| 28 | + |
| 29 | +### Type System |
| 30 | + |
| 31 | +SystemScript implements a strong, static type system with: |
| 32 | + |
| 33 | +- Primitive types (integers, floats, booleans, characters) |
| 34 | +- Derived types (pointers, references, arrays, slices, strings) |
| 35 | +- User-defined types (structures, enumerations, unions) |
| 36 | +- Type inference where unambiguous |
| 37 | +- Generic type parameters |
| 38 | + |
| 39 | +### Memory Management |
| 40 | + |
| 41 | +Multiple memory management strategies available: |
| 42 | + |
| 43 | +- Manual allocation and deallocation |
| 44 | +- Reference counting |
| 45 | +- Region-based allocation |
| 46 | +- Stack allocation |
| 47 | +- Direct memory mapping for hardware access |
| 48 | + |
| 49 | +### Concurrency Model |
| 50 | + |
| 51 | +Built-in concurrency primitives: |
| 52 | + |
| 53 | +- Native thread support |
| 54 | +- Atomic operations |
| 55 | +- Synchronization primitives (mutexes, read-write locks) |
| 56 | +- Async/await syntax |
| 57 | +- Coroutines and generators |
| 58 | + |
| 59 | +### Safety Mechanisms |
| 60 | + |
| 61 | +Safety enforced through: |
| 62 | + |
| 63 | +- Default bounds checking |
| 64 | +- Null pointer validation |
| 65 | +- Explicit unsafe blocks for unchecked operations |
| 66 | +- Memory protection attributes |
| 67 | +- Compile-time verification where possible |
| 68 | + |
| 69 | +## Platform Support |
| 70 | + |
| 71 | +### Operating Systems |

| 73 | +- Linux (all distributions) |
| 74 | +- Windows (7 and later) |
| 75 | +- macOS (10.12 and later) |
| 76 | +- FreeBSD |
| 77 | +- OpenBSD |
| 78 | +- Bare metal (no OS) |
| 79 | + |
| 80 | +### Architectures |
| 81 | + |
| 82 | +- x86 (32-bit) |
| 83 | +- x86_64 (64-bit) |
| 84 | +- ARM (32-bit) |
| 85 | +- ARM64 (AArch64) |

|
| 169 | +import system.io; |
| 170 | +
|
| 171 | +fn main() -> i32 { |
