Some pry commands:

  1. binding.pry to set "breakpoint"
  2. disable-pry to disable all breakpoints
  3. ls to look around
  4. whereami to see code above and below. whereami -n X to specify X lines above and below
  5. cd <object> to go into a particular object
  6. quit to continue running code until the next binding.pry line

Note that your gemfile should have the following if you want to actually use pry-debugger:

gem 'pry-debugger'
