Ruby In-Depth Reference

Comprehensive reference for the Ruby programming language and its reference implementation (MRI/CRuby) — covering the object model, metaprogramming, core types, control flow, I/O and encoding, concurrency, garbage collection, the RubyGems/Bundler package system, the interpreter CLI and tooling, environment variables, and the standard library.

Data Flow

Source file (.rb)

    → YARV compiler (compile AST to bytecode instructions)
      → YARV VM (per-instruction dispatch)
        → runtime services (ObjectSpace, GC, Thread scheduler, load path)
          → I/O, exit
