Editing Ruby (programming language) (section)

=== Matz's Ruby interpreter ===

The original Ruby [[interpreter (computer software)|interpreter]] is often referred to as [[Ruby MRI|Matz's Ruby Interpreter]] or MRI. This implementation is written in C and uses its own Ruby-specific [[virtual machine]].

The standardized and retired Ruby 1.8 [[Ruby MRI|implementation]] was written in [[C (programming language)|C]], as a single-pass [[interpreted language]].<ref name="1.8.7-retirement"/>

Starting with Ruby 1.9, and continuing with Ruby 2.x and above, the official Ruby interpreter has been [[YARV]] ("Yet Another Ruby VM"), and this implementation has superseded the slower virtual machine used in previous releases of MRI.
