The Ruby Compiler Survey

The Ruby Compiler Survey is a project cataloguing, preserving, and dissecting compilers for the Ruby programming language. In this context, a compiler is something that eventually produces machine code from Ruby code, whether that’s ahead-of-time or just-in-time. There are a surprisingly large number of attempts to write compilers for Ruby, using very varied approaches, so a comparative study is interesting. Some of these compilers were being lost to time and action was needed now to preserve and document them.
