Vim smart insert semicolon

Question

Is there a Vim plugin that can handle smart semicolon insertion, like the one in Eclipse?

Example (pipe character is insertion cursor):

foobar(|)
         


        

Answer 1

inoremap  ; getline('.')[-1:] == ';' ? '\' : ';'

The code above will check if there is ; at the end of the line.

If ; not exists, then it will add ; otherwise do nothing.
