def sort_a_file
  #
  # Part 1: Define the file (in the project's root directory)
  filename  = "supercalifragilistic_expialidocious.txt"
  #
  # Part 2: Sort the contents
  file_handle = File.new(filename)        # Create a File's I/O Source variable
  
    # ---------------------------------------------------------------------
    #                                     # Optionally, an I/O Source variable
    #                                     # may have been opened with the 'r'
    #                                     # flag meaning 'readable'
    #
    # file_handle = File.open(filename, 'r')
    # ---------------------------------------------------------------------
    
  lines       = file_handle.readlines     # Read all lines from the I/O source
  file_handle.close                       # Close the I/O source
  #
  # Part 3: Sort the contents
  lines.sort!                             # Sort all the lines read
  #
  # Part 4: Write the contents back
  file_handle = File.open(filename, 'w')  # Set a I/O Source as a writeable file
  file_handle.write(lines)                # Write all lines into the I/O Source
  file_handle.close                       # Close the I/O source

# Execute the method at start

Instructions

This is more of a simple feature and/or a tool, and not really used as a game system in itself. Comically, I've used it to sort through massive lists I've accumulated.



FAQ

A lot of the file size is from comments explaining what each line generally performs.



Compatibility

Given it is nothing but RUBY, it isn't just an RMXP script but should work cross-Ruby-platform.



Terms and Conditions

No credit required. Its too simple.
