Understanding Ruby Proc Internals Through proc.c

May 26, 2026 Ruby’s elegance hides an extremely sophisticated runtime underneath. Features like blocks, lambdas, closures, binding, method(:foo), and even &:to_s rely on a dense set of VM internals implemented in CRuby’s proc.c. This file is one of the best entry points for understanding how Ruby models executable code objects. The source analyzed here comes … Continue reading Understanding Ruby Proc Internals Through proc.c

MRI Internals: How Ruby Arrays Became a VM Playground

May 12, 2026 If you still think Ruby’s Array is β€œjust a C struct with some methods on top,” you’re about 5 years out of date. Modern MRI tells a very different story. Today, Array sits at the intersection of: Ruby code (array.rb) VM intrinsics (Primitive.*) C runtime (array.c) JIT specialization (YJIT) And the result … Continue reading MRI Internals: How Ruby Arrays Became a VM Playground
