" File: autoclose.vim
" Author: Karl Guertin <grayrest@gr.ayre.st>
" Version: 1.2
" Last Modified: June 18, 2009
" Description: AutoClose, closes what's opened.
"
" This plugin closes opened parenthesis, braces, brackets, quotes as you
" type them. As of 1.1, if you type the open brace twice ({{), the closing
" brace will be pushed down to a new line.
"
" You can enable or disable this plugin by typing \a (or <Leader>a if you
" changed your Leader char). You can define your own mapping and will need
" to do so if you have something else mapped to \a since this plugin won't
" clobber your mapping. Here's how to map \x:
"
" nmap <Leader>x <Plug>ToggleAutoCloseMappings
"
" You'll also probably want to know you can type <C-V> (<C-Q> if mswin is
" set) and the next character you type doesn't have mappings applied. This
" is useful when you want to insert only an opening paren or something.
"
" NOTE: If you're using this on a terminal and your arrow keys are broken,
" be sure to :set ttimeout and :set ttimeoutlen=100
"
" Version Changes: --------------------------------------------------{{{2
" 1.2 -- Fixed some edge cases where double the closing characters are
" entered when exiting insert mode.
" Finally (!) reproduced the arrow keys problem other people were
" running into and fixed.
" Typing a closing character will now behave consistently (jump
" out) regardless of the plugin's internal state.
"
" As a part of the close fix, I've opted to not try tracking the
" position of the closing characters through all the things that
" could be done with them, so arrowing/jumping around and not
" winding up back where you started will cause the input to not be
" repeatable.
" June 18, 2009
" 1.1.2 -- Fixed a mapping typo and caught a double brace problem,
" September 20, 2007
" 1.1.1 -- Missed a bug in 1.1, September 19, 2007
" 1.1 -- When not inserting at the end, previous version would eat chars
" at end of line, added double open->newline, September 19, 2007
" 1.0.1 -- Cruft from other parts of the mapping, knew I shouldn't have
" released the first as 1.0, April 3, 2007
