What would you like to do?

TLDR. I have two questions, though... the first one got answered after I typed all this up.

  1. How can I access objects inside of another object. (SOMEONE GAVE ME AN ANSWER. Feel free to skip to #2)

  2. I've attached by pry error output and gem list below, as will as troubleshooting and steps to reproduce it on my machine. (It's functionality is intermittent)

More detail on how I got the answer to #1

I was using IRB instead of Pry, couldn't tell that the objects were inside of an array. So, it's an array, so I can iterate through it with all the enumerables.

I was also causing myself probems because I'd not included attr_reader on appropriate Child variables, so I coudln't get to them when I DID try iterating through the array (before I knew for sure that it was an array.)

2. Troubleshooting Pry

Pry works if it's the only gem installed. It's working right now, because I've removed both pry-state and pry-byebug.

If I install pry-state or pry-byebug, I get the errors copied below anytime I enter a pry session, either by calling pry from the command line, or running a ruby file and hitting binding.pry.

I'd like to have some sort of debugger inside of pry, be it pry-state OR pry-byebug (or both!)

Finally, in case it's relevant, I edited my .pryrc file to customize the prompt:

# pulled from https://github.com/pry/pry/issues/493, slightly customized
Pry.prompt = [
  proc { |obj, nest_level, pry| "[#{pry.input_array.size}] \e[0;32mpry> \e[0m"},
]
