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

  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
  

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 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 氓.
  
  To fix the issue, you need remap or disable the related shortcut.
