Efficient, expressive, elegant
Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula.
- Nim generates native dependency-free executables, not dependent on a virtual machine, which are small and allow easy redistribution.
- The Nim compiler and the generated executables support all major platforms like Windows, Linux, BSD and macOS.
- Nim's memory management is deterministic and customizable with destructors and move semantics, inspired by C++ and Rust. It is well-suited for embedded, hard-realtime systems.
- Modern concepts like zero-overhead iterators and compile-time evaluation of user-defined functions, in combination with the preference of value-based datatypes allocated on the stack, lead to extremely performant code.
- Nim is self-contained: the compiler and the standard library are implemented in Nim.
- Nim has a powerful macro system which allows direct manipulation of the AST, offering nearly unlimited opportunities.
- Macros cannot change Nim's syntax because there is no need for it — the syntax is flexible enough.
- Modern type system with local type inference, tuples, generics and sum types.
- Statements are grouped by indentation but can span multiple lines.
