hello();
world();
}|
(then press <M-b> at | to do backinsert)
output:
{
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 <C-O>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](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 '.'.
After version 7.4.849, Vim implements new keyword <C-G>U to avoid the break
Solution: Update Vim to 7.4.849+

See |Fly Mode| section for details
==============================================================================
3. Fly Mode *autopairs-flymode*
Fly Mode will always force closed-pair jumping instead of inserting. Only for
")", "}", "]". If jumps in mistake, you can use |g:AutoPairsBackInsert| (default
Key: <M-b>) to jump back and insert closed pair.
The most situation maybe you want to insert single closed pair in the string,
eg: >
")"
Fly Mode is DISABLED by default. To enable Fly Mode add following to your
'.vimrc': >
let g:AutoPairsFlyMode = 1
Default Options: >
let g:AutoPairsFlyMode = 0
let g:AutoPairsShortcutBackInsert = '<M-b>'
==============================================================================
4. Shortcuts *autopairs-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|)
To rebind keys <M-p>, <M-e> or <M-n> or in case of conflicts with
another keys:
let g:AutoPairsShortcutToggle = '<another key>'
If the key is empty string '', then the shortcut will be disabled.
==============================================================================
5. Options *autopairs-options*
*g:AutoPairs*
|g:AutoPairs| dict
Default: >
{'(':')', '[':']', '{':'}',"'":"'",'"':'"', '`':'`'}
Specifies which symbols should be automatically paired.
To append new pairs without overwriting defaults, add values in your `.vimrc`.:
let g:AutoPairs['<']='>'
This example will enable matching of `<` with `>`.
*b:AutoPairs*
|b:AutoPairs| dict
Default: |g:AutoPairs|
Buffer level pairs set.
You can set |b:AutoPairs| before |BufEnter|: >
au Filetype FILETYPE let b:AutoPairs = {"(": ")"}
This sets |AutoPairs| to only match for parenthesis for 'FILETYPE'.
*g:AutoPairsShortcutToggle*
|g:AutoPairsShortcutToggle| string
Default: <M-p>
The shortcut to toggle autopairs.
*g:AutoPairsShortcutFastWrap*
|g:AutoPairsShortcutFastWrap| string
Default: <M-e>
Fast wrap the word. All pairs will be considered as a block (including <>).
(|)'hello' after fast wrap at |, the word will be ('hello')
(|)<hello> after fast wrap at |, the word will be (<hello>)
*g:AutoPairsShortcutJump*
|g:AutoPairsShortcutJump| string
Default: <M-n>
Jump to the next closed pair.
*g:AutoPairsShortcutBackInsert*
|g:AutoPairsShortcutBackInsert| string
Default: <M-b>
Work with |autopairs-flymode|, insert the key at the Fly Mode jumped position.
*g:AutoPairsMapBS*
|g:AutoPairsMapBS| int
Default: 1
Map <BS> to delete brackets and quotes in pair, executes:
inoremap <buffer> <silent> <BS> <C-R>=AutoPairsDelete()<CR>
*g:AutoPairsMapCh*
|g:AutoPairsMapCh| int
Default: 1
Map <C-h> to delete brackets and quotes in pair.
*g:AutoPairsMapCR*
|g:AutoPairsMapCR| int
Default: 1
Map <CR> to insert a new indented line if cursor in (|), {|} [|], '|', "|".
Executes:
inoremap <buffer> <silent> <CR> <C-R>=AutoPairsReturn()<CR>
*g:AutoPairsCenterLine*
|g:AutoPairsCenterLine| int
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*
|g:AutoPairsMapSpace| int
Default: 1
Map <space> to insert a space after the opening character and before the
closing one.
Executes:
inoremap <buffer> <silent> <CR> <C-R>=AutoPairsSpace()<CR>
*g:AutoPairsFlyMode*
|g:AutoPairsFlyMode| int
Default: 0
Set it to 1 to enable |autopairs-flymode|.
*g:AutoPairsMultilineClose*
|g:AutoPairsMultilineClose| int
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.
==============================================================================
6. Troubleshooting *autopairs-troubleshooting*
This plugin remaps 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 conflicts 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.
--- Swedish Character Conflict ---
Because AutoPairs uses Meta(Alt) key as a shortcut, it conflicts with some
Swedish character such as å. To fix the issue, you need remap or disable the
related shortcut.
