i need small console themes moving text , blinking text timeout, etc. need without graphics.

i don't have limited questions jumbled words game, if user press ctrl+c or ctrl+d should print score in alert box.

also if press ctrl+c or ctrl+d, errors printing in console. don't want print. how do this?

here code:

class string def black;          "\e[30m#{self}\e[0m" end def red;            "\e[31m#{self}\e[0m" end def green;          "\e[32m#{self}\e[0m" end def brown;          "\e[33m#{self}\e[0m" end def blue;           "\e[34m#{self}\e[0m" end def magenta;        "\e[35m#{self}\e[0m" end def cyan;           "\e[36m#{self}\e[0m" end def gray;           "\e[37m#{self}\e[0m" end  def bg_black;       "\e[40m#{self}\e[0m" end def bg_red;         "\e[41m#{self}\e[0m" end def bg_green;       "\e[42m#{self}\e[0m" end def bg_brown;       "\e[43m#{self}\e[0m" end def bg_blue;        "\e[44m#{self}\e[0m" end def bg_magenta;     "\e[45m#{self}\e[0m" end def bg_cyan;        "\e[46m#{self}\e[0m" end def bg_gray;        "\e[47m#{self}\e[0m" end  def bold;           "\e[1m#{self}\e[22m" end def italic;         "\e[3m#{self}\e[23m" end def underline;      "\e[4m#{self}\e[24m" end def blink;          "\e[5m#{self}\e[25m" end def reverse_color;  "\e[7m#{self}\e[27m" end end   puts "\n\t\t\t\tselect game level\n".magenta.bold puts "\t\t\t\t\t 1. easy ".brown.bold puts "\t\t\t\t\t 2. intermediate ".brown.bold puts "\t\t\t\t\t 3. difficult ".brown.bold  $opt=gets.chomp  # read word word randomly:  def read_word()     if $opt == "1"  # easy level- 4 character words          word=file.read('/usr/share/dict/words').lines.select {|l| (3..4).cover?(l.strip.size)}.sample.strip      elsif $opt == "2" # intermediate level - 4 9 characters words         word=file.read('/usr/share/dict/words').lines.select {|l| (4..9).cover?(l.strip.size)}.sample.strip      elsif $opt == "3" # difficult level - 9 10 characters words         word=file.read('/usr/share/dict/words').lines.select {|l| (9..19).cover?(l.strip.size)}.sample.strip      else         puts "in valid option"         exit 0     end     suffle(word) end   # suffle characters in words , parse validate function def suffle(word)     puts "#{word}".split(//).sort_by{rand}.join     puts word=word.downcase     validate(word) end   # read word stdin , validate def validate(word)     input=gets.chomp     input=input.downcase     if input.eql? word          puts "you right. next word".brown         read_word()     else         # if press enter below error printed. ignore checked input.length != 0         if input.length != 0                 puts "try again please".red.bg_black.italic             validate(word)         else             validate(word)         end     end end read_word()
