Object model intro
Raw
obj_model_intro_gamut.md

The Ruby Object Model (intro) aka "How Ruby Works"

What

The underlying structures that Ruby uses to interpret your code

Why

More effective (explains more, simpler) than whatever you're otherwise doing

Plan

  • Memorize
    • Symbol table (a hash table, its keys are always symbols)
    • Almost all of Ruby is implemented in 3 core structures
      • Object (data / noun)
        • store instance variables (symbol table)
        • store class pointer
      • Class (procedure / verb)
        • store instance methods (symbol table)
        • store superclass pointer
      • Binding (aka scope... stored on the stack)
        • store local variables (symbol table)
        • store self pointer
  • Quick chat... maybe
