This plugin was born as a personal need to get some little special
features from other editors into my preferred one. The Eclipse IDE editor has an auto-complete for open-close pair of characters feature that I always wanted into Vim.
As soon as you type a character that could have a matching (closing)
counterpart, Eclipse automatically puts its counterpart in front of your cursor, and it is smart enough to ignore the closing character afterwards, if typed, but just moves your cursor one character forward.
But the Eclipse editor does not stop there. If you type an opening
character on any part of your code that should not have a pair completion, it will not insert the closing character for you.
The AutoClose plugin is an attempt to reproduce this behavior for Vim.
