What is the difference between BufRead and BufEnter?

Question

I am confused between the two events BufRead and BufEnter. What is the difference between them?

Some example scenarios where I would choose one

Answer 1

BufRead is triggered after the buffer has been populated with the content of a file.

BufEnter is triggered after you enter a buffer for editing.

You may use BufNew, BufRead or BufAdd if you want to do something upon the creation of the buffer: setting some global variable, populating a buffer list of your own for use in a script.

You may use BufEnter when you want to set specific options depending on the filetype or whatever.
