Gives Pry _1, _2, _3, etc. variables (`_n` is equivalent to `_out_[n]`).
require 'binding_of_caller'
class Object
def method_missing(name, *args)
if name =~ /^_(\d+)$/
binding.of_caller(2).eval("self").output_array[$1.to_i]
else
super
end
end

Turning 'p' into a method that can be run on any object.
[1] pry(main)> module Kernel; alias old_p p; def p(*args); if args.any?; old_p(*args.dup); else; old_p(self); end; nil; end; end
=> nil
[2] pry(main)> p [1,2,3]
[1, 2, 3]
=> nil
[3] pry(main)> [1,2,3].each(&:p)
1
2
3
=> [1, 2, 3]

Put Pry's history in different files (by date).

## History
PRY_CONFIG_DIR = File.expand_path("~/.pry")
Pry.history.loader = proc do |&block|
Dir["#{PRY_CONFIG_DIR}/history-*.log"].sort_by { |f| File.mtime f }.last(2).each do |fn|
File.foreach(fn) { |line| block.call(line) }
end
