Well, the obvious first step would be not redirecting stdin from /dev/null.
It's kinda hard to get useful data from there.

What is this supposed to do?  You have a loop that reads stdin until
EOF, and then you have another process that wants to read the same stdin
after EOF.

Did you want vim to read from the user's terminal instead of script's stdin?
If that's the case, then:

vim main.sh </dev/tty

It would help if you would SAY what you are doing, instead of always
making people guess.  There's plenty of room left in the email for
a description of the problem.

By the way, read -d $'\n' is redundant.  That's just the same as read.
