            hello();}|
            world();
        }

        See Fly Mode section for details

Fly Mode
--------
Fly Mode will always force closed-pair jumping instead of inserting. only for ")", "}", "]"

If jumps in mistake, could use AutoPairsBackInsert(Default Key: `<M-b>`) to jump back and insert closed pair.

the most situation maybe want to insert single closed pair in the string, eg ")"

Fly Mode is DISABLED by default.

add **let g:AutoPairsFlyMode = 1** .vimrc to turn it on

Default Options:

    let g:AutoPairsFlyMode = 0
    let g:AutoPairsShortcutBackInsert = '<M-b>'

Shortcuts
---------

    System Shortcuts:
        <CR>  : Insert new indented line after return if cursor in blank brackets or quotes.
        <BS>  : Delete brackets in pair
        <M-p> : Toggle Autopairs (g:AutoPairsShortcutToggle)
        <M-e> : Fast Wrap (g:AutoPairsShortcutFastWrap)
        <M-n> : Jump to next closed pair (g:AutoPairsShortcutJump)
        <M-b> : BackInsert (g:AutoPairsShortcutBackInsert)

    If <M-p> <M-e> or <M-n> conflict with another keys or want to bind to another keys, add

        let g:AutoPairShortcutToggle = '<another key>'

    to .vimrc, if the key is empty string '', then the shortcut will be disabled.

Options
-------
*   g:AutoPairs

        Default: {'(':')', '[':']', '{':'}',"'":"'",'"':'"', '`':'`'}

*   b:AutoPairs

        Default: g:AutoPairs

        Buffer level pairs set.

*   g:AutoPairsShortcutToggle

        Default: '<M-p>'

        The shortcut to toggle autopairs.

*   g:AutoPairsShortcutFastWrap

        Default: '<M-e>'

        Fast wrap the word. all pairs will be consider as a block (include <>).
        (|)'hello' after fast wrap at |, the word will be ('hello')
        (|)<hello> after fast wrap at |, the word will be (<hello>)

*   g:AutoPairsShortcutJump

        Default: '<M-n>'

        Jump to the next closed pair

*   g:AutoPairsMapBS

        Default : 1

        Map <BS> to delete brackets, quotes in pair
        execute 'inoremap <buffer> <silent> <BS> <C-R>=AutoPairsDelete()<CR>'

*   g:AutoPairsMapCR

        Default : 1

        Map <CR> to insert a new indented line if cursor in (|), {|} [|], '|', "|"
        execute 'inoremap <buffer> <silent> <CR> <C-R>=AutoPairsReturn()<CR>'

*   g:AutoPairsCenterLine

        Default : 1

        When g:AutoPairsMapCR is on, center current line after return if the line is at the bottom 1/3 of the window.

*   g:AutoPairsMapSpace

        Default : 1

        Map <space> to insert a space after the opening character and before the closing one.
        execute 'inoremap <buffer> <silent> <CR> <C-R>=AutoPairsSpace()<CR>'

*   g:AutoPairsFlyMode

        Default : 0

        set it to 1 to enable FlyMode.
        see FlyMode section for details.

*   g:AutoPairsShortcutBackInsert

        Default : <M-b>

        Work with FlyMode, insert the key at the Fly Mode jumped postion

Buffer Level Pairs Setting
--------------------------

Set b:AutoPairs before BufEnter

eg:

    " When the filetype is FILETYPE then make AutoPairs only match for parenthesis
    au Filetype FILETYPE let b:AutoPairs = {"(": ")"}

TroubleShooting
---------------
    The script will remap keys ([{'"}]) <BS>,
    If auto pairs cannot work, use :imap ( to check if the map is corrected.
    The correct map should be <C-R>=AutoPairsInsert("\(")<CR>
    Or the plugin conflict with some other plugins.
    use command :call AutoPairsInit() to remap the keys.


* How to insert parens purely

    There are 3 ways

    1. use Ctrl-V ) to insert paren without trigger the plugin.

    2. use Alt-P to turn off the plugin.

    3. use DEL or <C-O>x to delete the character insert by plugin.


Known Issues
-----------------------
There are the issues I cannot fix.

Compatible with Vimwiki - [issue #19](https://github.com/jiangmiao/auto-pairs/issues/19)

    Description: When works with vimwiki `<CR>` will output `<SNR>xx_CR()`
    Reason: vimwiki uses `<expr>` on mapping `<CR>` that auto-pairs cannot expanding.
    Solution A: Add

        " Copy from vimwiki.vim s:CR function for CR remapping
        function! VimwikiCR()
          let res = vimwiki#lst#kbd_cr()
          if res == "\<CR>" && g:vimwiki_table_mappings
            let res = vimwiki#tbl#kbd_cr()
          endif
          return res
        endfunction
        autocmd filetype vimwiki inoremap <buffer> <silent> <CR> <C-R>=VimwikiCR()<CR><C-R>=AutoPairsReturn()<CR>

    to .vimrc, it will make vimwiki and auto-pairs 'Return' feature works together.

    Solution B: add `let g:AutoPairsMapCR = 0` to .vimrc to disable `<CR>` mapping.

Compatible with viki - [issue #25](https://github.com/jiangmiao/auto-pairs/issues/25)

    Description: When works with viki `<CR>` will output viki#ExprMarkInexistentInElement('ParagraphVisible','<CR>')
    Reason: viki uses `<expr>` on mapping `<CR>` that auto-pairs cannot expanding.
    Solution A: Add

        autocmd filetype viki inoremap <buffer> <silent> <CR> <C-R>=viki#ExprMarkInexistentInElement('ParagraphVisible',"\n")<CR><C-R>=AutoPairsReturn()<CR>`

    to .vimrc, it will make viki and auto-pairs works together.

    Solution B: add `let g:AutoPairsMapCR = 0` to .vimrc to disable `<CR>` mapping.

    Remarks: Solution A need NOT add `let g:AutoPairsMapCR = 0` to .vimrc, if Solution A still cannot work, then have to use Solution B to disable auto-pairs `<CR>`.

Breaks '.' - [issue #3](https://github.com/jiangmiao/auto-pairs/issues/3)

    Description: After entering insert mode and inputing `[hello` then leave insert
                 mode by `<ESC>`. press '.' will insert 'hello' instead of '[hello]'.
    Reason: `[` actually equals `[]\<LEFT>` and \<LEFT> will break '.'
    Solution: none
