🛠️ Preprocess and Transform Input

Intercept and transform user input before IRB evaluates it. Useful for auto-wrapping methods or injecting debugging hooks.

module IRB
  class InputTransformer
    def transform(line)
      # Auto-wrap single-line `foo` calls in puts for quick inspection
      if line.strip =~ /^\w+$/
        "puts(#{line.strip})"
      else
        super
      end
    end
  end
end

Place this in ~/.irbrc to automatically wrap bare identifiers in puts. You can use this hook to inject logging, profiling, or custom DSL expansion.
