Welcome to Nim
Nim (formerly known as "Nimrod") is a statically typed, imperative programming language that tries to give the programmer ultimate power without compromises on runtime efficiency. This means it focuses on compile-time mechanisms in all their various forms.
Beneath a nice infix/indentation based syntax with a powerful (AST based, hygienic) macro system lies a semantic model that supports a soft realtime GC on thread local heaps. Asynchronous message passing is used between threads, so no "stop the world" mechanism is necessary. An unsafe shared memory heap is also provided for the increased efficiency that results from that model.
Tags and Flavors
Image tags indicate Nim versions. The latest stable version is additionally tagged with latest, the latest development version—with devel.
Images come in three flavors: regular, slim, and onbuild. Regular images include the Nim compiler and Nimble package manager. Slim images include only the compiler. Onbuild images are meant to be used in Dockerfiles for Nimble packages because they invoke nimble build on build.
