# Nim — Statically Typed Compiled Language That Feels Like Python

## Quick Use
```bash
# Install Nim via choosenim
curl https://nim-lang.org/choosenim/init.sh -sSf | sh

# Hello world
echo 'echo "Hello, Nim!"' > hello.nim
nim c -r hello.nim
```

## Introduction
Nim is a statically typed compiled systems programming language that combines Python-like readability with the performance of C. It compiles to C, C++, Objective-C, or JavaScript, making it suitable for systems programming, web backends, scripting, and game development.

## What Nim Does
- Compiles to C/C++/JS for native or browser-based execution
- Provides powerful metaprogramming through templates and macros
- Supports multiple memory management strategies including ARC and ORC
- Offers a comprehensive standard library covering IO, networking, and parsing
- Enables cross-compilation to virtually any platform with a C compiler

## Architecture Overview
Nim's compiler parses source into an AST, runs macro expansions, performs semantic analysis with type inference, and emits C (or other target) source code. The generated C is then compiled by GCC, Clang, or MSVC. The ORC memory manager uses reference counting with a cycle collector, providing deterministic cleanup without stop-the-world pauses.

## Self-Hosting & Configuration
- Install via `choosenim` or your OS package manager
- Manage dependencies with `nimble`, Nim's built-in package manager
- Configure compiler options in `nim.cfg` or `config.nims` files
- Cross-compile by specifying `--cpu` and `--os` flags
- Use `nim doc` to generate HTML documentation from source comments

## Key Features
- Indentation-based syntax familiar to Python developers
- Compile-time code execution and AST manipulation via macros
- Deterministic memory management with ARC/ORC (no tracing GC needed)
- Uniform function call syntax for clean method-chaining style
- First-class async/await for non-blocking IO

## Comparison with Similar Tools
- **Python** — Nim has similar syntax but is compiled and statically typed, offering much higher runtime speed
- **Rust** — Rust has stricter safety guarantees; Nim is easier to learn with faster compile times
- **Go** — Go uses a GC and has no generics templates; Nim offers more compile-time flexibility
- **V** — V is newer with fewer libraries; Nim has a mature ecosystem and proven macro system
- **Crystal** — Crystal compiles via LLVM with Ruby-like syntax; Nim compiles via C with Python-like syntax

## FAQ
**Q: What memory management does Nim use?**
A: Nim defaults to ORC, an automatic reference counting system with a cycle collector. You can also choose ARC (no cycle collector) or manual memory management.

**Q: Can Nim compile to JavaScript?**
A: Yes. Nim has a JavaScript backend, enabling code sharing between server and browser.

**Q: How mature is the Nim ecosystem?**
A: Nim has been in development since 2008 and has a stable 2.x release series with thousands of community packages on the Nimble directory.

**Q: Is Nim suitable for embedded or real-time systems?**
A: Yes. With ARC and manual memory management, Nim can run on resource-constrained platforms with deterministic behavior.
