Enumerating the contents of a file split with a symbol

each_with_symbol.rb

# Enumerable module provides most of the list traversal classes, some of which are mixed-in to File class.
# #each_line, #each_slice etc are such methods. 

# What if you need to split against a custom symbol. This is particularly useful while processing reports or logs.
# For instance, one of the reports I get is see is of this format:

# \e!C\r
# <some header data>
# -----------------------------------------------------------------------
# Name           Account        Address               DoB
# -----------------------------------------------------------------------
# Some name      Some account   Some address          Some date of birth


# The \e!C\r is an escape character that presumably defines the start of the page for printer. The records in the file are not 
# uniform. One page might have only 4 lines whereas the next page may have full number of rows. The pages can be split like so:


class File
  def each_page(&block)
    read.split("\e!C\r").each do |page|
      block.call(page)
    end
  end
end

File.open("report.txt") do |file|
  file.each_page do |page|
    # do stuff to that page
  end
end
