Redis reply formatter

bash

#!/bin/bash

# define the formatter for 'sed' script
# the formatter will arrange and combine data to a line 
FORMATTER=':a;N;$!ba'   # define the label for removing the new line "\n"
FORMATTER+=';/\n\./s/\.\n/\./g'
    # search the all indentation lines that start with "." and remove the new 
    # line "\n"
    # e.g:
    #
    #   ...                 ...2|
    #   2|             =>   (integer)
    #   (integer)           650
    #   650

FORMATTER+=';/\n\?(.\+\n/s/(integer)\n/(integer) /g'
    # search the all lines that that start with "(" and remove the new line "\n"
    # e.g:
    #
    #   ...                 ...
    #   2|                  2|
    #   (integer)       =>  (integer) 650
    #   650

FORMATTER+=';/^[0-9]\+|\n/s/|\n/) /g'
    # replace the all lines that that start with "1|", "2|",... "104|"... etc.
    # with "1) ", "2) ", "104) " and remove the new line "\n"
    # e.g:
    #
    #   ...                 ...
    #   2|                  2) (integer)
