Nim (formerly named Nimrod) is an imperative, multi-paradigm, compiled programming language designed and developed by Andreas Rumpf. It is designed to be "efficient, expressive, and elegant", supporting metaprogramming, functional, message passing, procedural, and object-oriented programming styles by providing several features such as compile time code generation, algebraic data types, a foreign function interface (FFI) with C and compiling to JavaScript, C and C++..

Example from Compiler Explorer:
# Type your code here, or load an example. proc square(num: int): int {.exportc.} = num * num
Example from Riju:
echo "Hello, world!"
Example from hello-world:
echo("Hello World")
Example from the Hello World Collection:
# Hello world in Nim echo "Hello World"
Example from Linguist:
# from: # Special configuration file for the Nim project # gc:markAndSweep hint[XDeclaredButNotUsed]:off path:"$projectPath/.." path:"$lib/packages/docutils" path:"$nim" define:useStdoutAsStdmsg symbol:nimfix define:nimfix cs:partial #define:useNodeIds define:booting define:noDocgen
Example from Wikipedia:
proc printf(formatstr: cstring) {.header: "<stdio.h>", varargs.} printf("%s %d\n", "foo", 5)
