What is the simplest way to compare the version of the file that I

Take a look at BBEdit it makes backups of every change you make to
text files, also look at Time Machine
Sample of BBEdit AUTOMATIC backups (I only show the content of one
day's worth). You don't have to anything BBEdit does it all
automatically.
Each of the backup directories at the bottom has similar contents :
