class Pry
# Default commands used by Pry.
# @notes
# @note
# If you plan to replace the default Commands class with a custom
# one then it must have a `commands` method that returns a Hash.
# The Hash should be set up so that the key is the command String
# (or Regexp)
class Commands
attr_accessor :out
def initialize(out)
@out = out
end
# This method returns a hash that defines the commands implemented for the REPL session.
# The hash has the following form:
#
# * Each key is a command, it should either be a String or a
# Regexp or an Array.
# * Where it is an Array, each element should be a String or a
# Regexp, and the elements are considered to be aliases.
# * Each value is the action to take for the command. The value
# should be a `proc`.
# * If the proc needs to generate output it should write to the
# `opts[:output]` object, as follows: `opts[:output].puts "hello world"`
# * When the proc is invoked it is passed parameters in the form
# of an options hash, the parameters are as follows:
#
# * `opts[:val]` The current line of input.
# * `opts[:eval_string]` The cumulative lines of input for a multi-line input.
# * `opts[:target]` The receiver of the Pry session.
# * `opts[:nesting]` The nesting level of the current Pry Session.
# * `opts[:output]` The `output` object for the current Pry session.
# * `opts[:captures]` The Regexp captures for the command (if
# any) - This can be used to implement command parameters.
#
# @return [Hash] The commands hash.
# @example A 'hello' command.

# /^hello\s*(.+)/ => proc do |opts|
