NIM(7)

AUTHORS: Andreas Rumpf
HISTORY: Andreas Rumpf, a German developer, started the language in 2008 under the name Nimrod, aiming to combine Python-like readability with the speed of C and powerful compile-time metaprogramming. Instead of generating machine code directly, its compiler emits C, C++ or JavaScript and lets existing compilers do the rest. The language was renamed Nim in 2014 and reached version 1.0 in 2019.
USAGE: A niche language with a small, dedicated community. It is used for command-line tools, games, scripting and some systems work, and notably for Nimbus, an Ethereum client developed by Status.
