require "pry"

### REPL EXAMPLE
#
# ARGV array holds any additional parameters when the program is run
#
# STDIN.gets.chomp - waits for the user to input on the terminal
#
#


def command_line_repl
  case ARGV[0]

  when "help"
    puts "Here is a list of available commands:"
    puts "find 1 - find candidate with id 1"
    puts "all - all candidates"
    puts "qualified - qualified candidates"
    puts "quit"
  else
    puts "enter your command to continue"
    puts "available commands are: find [id], qualified, all, or quit"
    input = ""
    while !input.eql?("quit")
      # gets requests user to input a command
      # stored in variable input
      input = STDIN.gets.chomp
      commands_array = input.chomp.split(' ')
      if commands_array.length.eql?(1) && !commands_array[0].match(/quit/i)
        puts "command of qualified or all detected"
        # if statements to run appropriate methods qualified or all
      else
        puts "need to code here to run the find command if present"
        # check command_array for find 1 command
        # ie. commands_array[0] ==  "find"
        # then id = command_array[1]
        # execute find method or exit for next loop
      end
    end
