Prevent outputting 'Frame number' when guard is executed. pry-stack_explorer が Guard 実行時に常に表示されるのを防ぐ。

pry-stack_explorer.rb

# monkey-patch the whereami command to show some frame information,
# useful for navigating stack.
Pry.config.commands.before_command("whereami") do |num|
  if PryStackExplorer.frame_manager(_pry_) && !internal_binding?(target)
    bindings      = PryStackExplorer.frame_manager(_pry_).bindings
    binding_index = PryStackExplorer.frame_manager(_pry_).binding_index

    # Add here
    # Ignore outputs when Frame number: 0/0 or 0/1
    unless binding_index == 0 && bindings.size <= 2
      output.puts "\n"
      output.puts "#{Pry::Helpers::Text.bold('Frame number:')} #{binding_index}/#{bindings.size - 1}"
      output.puts "#{Pry::Helpers::Text.bold('Frame type:')} #{bindings[binding_index].frame_type}" if bindings[binding_index].frame_type
    end
  end
