## Features

- Insert in pair

      input: [
      output: [|]

- Delete in pair

      input: foo[<BS>]
      output: foo

      input: {|} (press <CR> at |)
      output: {
          |
      }          (press } to close the pair)
      output: {
      }|         (the inserted blank line will be deleted)

- Insert spaces before closing characters, only for [], (), {}

      {
          hello();}|
          world();
      }

      See Fly Mode section for details

- Multibyte Pairs

      Support any multibyte pairs such as <!-- -->, <% %>, """ """
      See multibyte pairs 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:AutoPairsShortcutToggle = '<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:AutoPairsMapCh

      Default : 1

      Map <C-h> to delete brackets, quotes in pair

- 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:AutoPairsMultilineClose

      Default : 1

      When you press the key for the closing pair (e.g. `)`) it jumps past it.
      If set to 1, then it'll jump to the next line, if there is only whitespace.
      If set to 0, then it'll only jump to a closing pair on the same line.

- g:AutoPairsShortcutBackInsert

      Default : <M-b>

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

- g:AutoPairsMoveCharacter

      Default: "()[]{}\"'"

      Map <M-(> <M-)> <M-[> <M-]> <M-{> <M-}> <M-"> <M-'> to
      move character under the cursor to the pair.

## 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 = {"(": ")"}
    au FileType php      let b:AutoPairs = AutoPairsDefine({'<?' : '?>', '<?php': '?>'})

## Multibyte Pairs

    The default pairs is {'(':')', '[':']', '{':'}',"'":"'",'"':'"', '`':'`'}
    You could also define multibyte pairs such as <!-- -->, <% %> and so on

- Function AutoPairsDefine(addPairs:dict[, removeOpenPairList:list])

      add or delete pairs base on g:AutoPairs

      eg:
          au FileType html let b:AutoPairs = AutoPairsDefine({'<!--' : '-->'}, ['{'])
          add <!-- --> pair and remove '{' for html file

      the pair implict start with \V, so if want to match start of line ^ should be write in \^ vim comment {'\^"': ''}

- General usage

      au FileType php      let b:AutoPairs = AutoPairsDefine({'<?' : '?>', '<?php': '?>'})

      the first key of closed pair ? will be mapped

      pairs: '<?' : '?>', '<?php': '?>'
      input: <?
      output: <?|?>

      input: <?php
      output: <?php|?>

      input: he<?php|?> (press <BS> at|)
      output: he|

      input: <?php|?> (press ? at|)
      output: <?php?>|

      pair: '[[':']]'
      input: [[|]] (press <BS>)
      output: | ([[ and ]] will be deleted the [['s priority is higher than [ for it's longer)

- Modifier

      The text after //  in close pair is modifiers

      n - do not map the first charactor of closed pair to close key
      m - close key jumps through multi line
      s - close key jumps only in the same line
      k[KEY] - map the close key to [KEY]

          by default if open key equals close key the multi line is turn off

          "<?": "?>"      ? jumps only in the same line
          "<?": "?>//m"   force ? jumping through multi line
          "<?php":"?>"    ? will jump through multi line
          "<?php":"?>//s" force ? only jumping in the same line
          "<?": "?>//n"   do not jump totally
          "<?": "?>//k]"  use key ] to jump through ?>

      for 'begin' 'end' pair, e is a charactor, if map e to jump will be annoy, so use modifier 'n' to skip key map

      au FileType ruby     let b:AutoPairs = AutoPairsDefine({'begin': 'end//n]'})

      input: begin
      output: begin|end

      input: begin|end (press <BS> on |)
      output: |

      input: begin|end (press e on |)
      output: begineend (will not jump for e is not mapped)

- Advanced usage

      au FileType rust     let b:AutoPairs = AutoPairsDefine({'\w\zs<': '>'})

      if press < after a word will generate the pair

      when use regexp MUST use \zs to prevent catching
      if use '\w<' without \zs,  for text hello<|> press <BS> on | will output 'hell', the 'o' has been deleted

      pair: '\w\zs<': '>'
      input: h <
      output: h <

      input: h<
      output: h<|>

      input: h<|> press <BS>
      output: h|

      pair: '\w<': '>' (WRONG pair which missed \zs)
      input: h<|> press <BS>
      output: | (charactor 'h' is deleted)

      the 'begin' 'end' pair write in

      au FileType ruby     let b:AutoPairs = AutoPairsDefine({'\v(^|\W)\zsbegin': 'end//n'})

      will be better, only auto pair when at start of line or follow non-word text

## 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 x to delete the character insert by plugin.

- Swedish Character Conflict

  Because AutoPairs uses Meta(Alt) key as shortcut, it is conflict with some Swedish character such as å. To fix the issue, you need remap or disable the related shortcut.

## Known Issues

Breaks ‘.’ - issue #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 '.'.
            After version 7.4.849, Vim implements new keyword <C-G>U to avoid the break
    Solution: Update Vim to 7.4.849+
