`msmn.pry`

[gazayas]

I'd like to have a method in Masamune::AbstractSyntaxTree called pry which will stop at each point in the code where the node matches pry's parameters:

msmn.pry(type: :variables, token: "n")

Ideally I want to show the node class (i.e. - Masamune::AbstractSyntaxTree::VarField), the data from Ripper specifically for that node, and the corresponding Masamune::AbstractSyntaxTree::LexNode.

Then you could press enter to show the next node in the tree until you reach the final node.

In the pry gem, binding.pry is usually placed somewhere inside the code, but msmn.pry would be placed outside of the code block that we instantiate Masamune::AbstractSyntaxTree.new(code) with. Then we would just call pry afterwards.

So, something like this.

code = <<~CODE
  10.times do |n|
    puts n
  end
CODE

msmn = Masamune::AbstractSyntaxTree.new(code)
msmn.pry(type: :variables, token: "n")

I'd recommend shifting this to irb instead, since IRB has pretty supplanted pry in terms of features and isn't as needed anymore.
