The joy of Ruby debugging - Pry universe
summary
Claims that Pry transforms Ruby debugging by letting code stop at runtime with binding.pry, inspect live objects including private methods, view source and docs, edit files and reload without restarting, and attach remotely with pry-remote. Demo walks through a Hanoi solver: Pry exposes a double-pop bug, permits in-place fix, and reruns tests until all assertions pass. Plugins like pry-rescue and pry-bug add automatic repl-on-exception and stack navigation so debugging becomes interactive and much faster.
