mRuby
mRuby (Minimalist Ruby) is an offshoot of official Ruby and is led by many of the same developers. It implements a subset of Ruby that’s designed for a minimal memory footprint and for use embedded inside C programs where memory might be tight, such as inside devices. The idea is to allow hardware developers access to Ruby as a scripting language.
You can install mRuby via your ruby version manager (rbenv install mruby-3.1.0), or you can install it standalone from the download site.[62] If you install it via a version manager, you can run it using ruby; if you install it standalone, the command is mruby.
