Nim

Nim

Nim is a system and applications programming language that is statically typed and compiled, designed to be efficient, expressive, and elegant. Being general-purpose it can fill a wide range of uses but has found a niche in game development and systems programming including embedded systems.

About Nim

Nim is a general-purpose language designed and developed by Andreas Rumpf and first appearing in 2008. Designed to be efficient, expressive, and elegant. Nim is statically typed and compiled but lets you write elegant code that runs efficiently. Nim lets you target many platforms by compiling code to C, C++, JavaScript, or Objective-C. Nim syntax is similar to Python and shares many of Python's characteristics but draws inspiration from a number of languages, such as C, C++, C#, Lisp, Ada, Go, Oberon, and others.

As Nim is a general-purpose language it can be used in various places but has been filling a real niche in the area of Game development and Systems Programming including Embedded systems.

Nim gives you a lot of the convenience you find in Python and other languages, like easy to read syntax, a package management system for using new libraries in your projects, and user-friendly tracebacks for debugging errors.

Nim gives you the speed and portability of C, but with a high-performance garbage-collector and elegant syntax that makes the language very approachable to new people. Nim also gives you control, letting you change the garbage-collector or turn it off completely giving you the option to manage memory yourself. You have a variety of programming paradigms and abstraction layers with Nim.

Key Features of Nim

Strong static typing

Modern static type system with type inference, tuples, generics, and sum types.

Fast

Compiles to C/C++/ObjC with no runtime or virtual machine, for blazing fast results.

Expressive

Friendly syntax, macro system and generics allow for expressive DSLs and code reusability.

Interoperable

Easy FFI with the target languages (C/C++/ObjC/JavaScript) for excellent interop.

Cross-platform

Runs on (and cross-compiles to) all major desktop OSs and embedded devices.

Custom memory management

Deterministic memory management, with destructors and move semantics (inspired by C++ and Rust).
