This repository contains patches (and ruby tarballs) which provide enhanced runtime support to allow beautiful, feature-rich debuggers or profilers for Ruby 1.9.x or 2.x. Some of the patches are useful for other things as well.

A debugger which makes use of all of these features is https://github.com/rocky/rb-trepanning.

Features

  • a call frame object (RubyVM::Frame)
  • support for fast debugger breakpoints, "step over" and "step out"
  • access to instruction sequences at runtime
  • access inside Ruby to VM registers
  • More accurate location information
  • access to C parameters in a C call
  • memory addresses of C functions (useful in conjunction with gdb)
  • seeing and changing event filters dynamically
