## nvim-autopairs
A super powerful autopair plugin for Neovim that supports multiple characters.
Requires neovim 0.7
## Installation
Install the plugin with your preferred package manager:
### [vim-plug](https://github.com/junegunn/vim-plug)
```vim
Plug 'windwp/nvim-autopairs'
lua << EOF
require("nvim-autopairs").setup {}
EOF
```
### [packer](https://github.com/wbthomason/packer.nvim)
```lua
use {
"windwp/nvim-autopairs",
config = function() require("nvim-autopairs").setup {} end
}
```
## Default values
``` lua
local disable_filetype = { "TelescopePrompt" }
local disable_in_macro = false -- disable when recording or executing a macro
local disable_in_visualblock = false -- disable when insert after visual block mode
local disable_in_replace_mode = true
local ignored_next_char = [=[[%w%%%'%[%"%.%`%$]]=]
local enable_moveright = true
local enable_afterquote = true -- add bracket pairs after quote
local enable_check_bracket_line = true --- check bracket in same line
local enable_bracket_in_quote = true --
local enable_abbr = false -- trigger abbreviation
local break_undo = true -- switch for basic rule break undo sequence
local check_ts = false
local map_cr = true
local map_bs = true -- map the <BS> key
local map_c_h = false -- Map the <C-h> key to delete a pair
local map_c_w = false -- map <c-w> to delete a pair if possible
```
### Override default values
``` lua
require('nvim-autopairs').setup({
disable_filetype = { "TelescopePrompt" , "vim" },
})
```
#### Mapping `<CR>`
```
Before Input After
------------------------------------
{|} <CR> {
|
}
------------------------------------
```
<details>
<summary><b>nvim-cmp</b></summary>
<h3>
You need to add mapping `CR` on nvim-cmp setup.
Check readme.md on nvim-cmp repo.
</h3>
``` lua
-- If you want insert `(` after select function or method item
local cmp_autopairs = require('nvim-autopairs.completion.cmp')
local cmp = require('cmp')
cmp.event:on(
'confirm_done',
cmp_autopairs.on_confirm_done()
)
```
You can customize the kind of completion to add `(` or any character.
```lua
local handlers = require('nvim-autopairs.completion.handlers')
cmp.event:on(
'confirm_done',
cmp_autopairs.on_confirm_done({
filetypes = {
-- "*" is a alias to all filetypes
["*"] = {
["("] = {
kind = {
cmp.lsp.CompletionItemKind.Function,
cmp.lsp.CompletionItemKind.Method,
},
handler = handlers["*"]
}
},
lua = {
["("] = {
kind = {
cmp.lsp.CompletionItemKind.Function,
cmp.lsp.CompletionItemKind.Method
},
---@param char string
---@param item item completion
---@param bufnr buffer number
handler = function(char, item, bufnr)
-- Your handler function. Inpect with print(vim.inspect{char, item, bufnr})
end
}
},
-- Disable for tex
tex = false
}
})
)
```
Don't use `nil` to disable a filetype. If a filetype is `nil` then `*` is used as fallback.

If you have a problem with indent after you press ` <CR> `
please check the settings of treesitter indent or install a plugin that has indent support for your filetype.
### Rule
nvim-autopairs uses rules with conditions to check pairs.
``` lua
local Rule = require('nvim-autopairs.rule')
local npairs = require('nvim-autopairs')
npairs.add_rule(Rule("$$","$$","tex"))
-- you can use some built-in conditions
local cond = require('nvim-autopairs.conds')
print(vim.inspect(cond))
npairs.add_rules({
Rule("$", "$",{"tex", "latex"})
-- don't add a pair if the next character is %
:with_pair(cond.not_after_regex("%%"))
-- don't add a pair if the previous character is xxx
:with_pair(cond.not_before_regex("xxx", 3))
-- don't move right when repeat character
:with_move(cond.none())
-- don't delete if the next character is xx
:with_del(cond.not_after_regex("xx"))
-- disable adding a newline when you press <cr>
:with_cr(cond.none())
},
-- disable for .vim files, but it work for another filetypes
Rule("a","a","-vim")
)
npairs.add_rules({
Rule("$$","$$","tex")
:with_pair(function(opts)
print(vim.inspect(opts))
if opts.line=="aa $$" then
-- don't add pair on that line
return false
end
end)
}
)
-- you can use regex
-- press u1234 => u1234number
npairs.add_rules({
Rule("u%d%d%d%d$", "number", "lua")
:use_regex(true)
})
-- press x1234 => x12341234
npairs.add_rules({
Rule("x%d%d%d%d$", "number", "lua")
:use_regex(true)
:replace_endpair(function(opts)
-- print(vim.inspect(opts))
return opts.prev_char:sub(#opts.prev_char - 3,#opts.prev_char)
end)
})
-- you can do anything with regex +special key
-- example press tab to uppercase text:
-- press b1234s<tab> => B1234S1234S
npairs.add_rules({
Rule("b%d%d%d%d%w$", "", "vim")
:use_regex(true,"<tab>")
:replace_endpair(function(opts)
return
opts.prev_char:sub(#opts.prev_char - 4,#opts.prev_char)
.."<esc>viwU"
end)
})
-- you can exclude filetypes
npairs.add_rule(
Rule("$$","$$")
:with_pair(cond.not_filetypes({"lua"}))
)
--- check ./lua/nvim-autopairs/rules/basic.lua
```
[Rules API](https://github.com/windwp/nvim-autopairs/wiki/Rules-API)
### Treesitter
You can use treesitter to check for a pair.
```lua
local npairs = require("nvim-autopairs")
local Rule = require('nvim-autopairs.rule')
npairs.setup({
check_ts = true,
ts_config = {
lua = {'string'},-- it will not add a pair on that treesitter node
javascript = {'template_string'},
java = false,-- don't check treesitter on java
}
})
local ts_conds = require('nvim-autopairs.ts-conds')
-- press % => %% only while inside a comment or string
npairs.add_rules({
Rule("%", "%", "lua")
:with_pair(ts_conds.is_ts_node({'string','comment'})),
Rule("$", "$", "lua")
:with_pair(ts_conds.is_not_ts_node({'function'}))
})
```
### Don't add pairs if it already has a close pair in the same line
if **next character** is a close pair and it doesn't have an open pair in same line, then it will not add a close pair
``` text
Before Input After
------------------------------------
( |)) ( ( (|))
```
``` lua
require('nvim-autopairs').setup({
enable_check_bracket_line = false
})
```
### Don't add pairs if the next char is alphanumeric
You can customize how nvim-autopairs will behave if it encounters a specific
character
``` lua
require('nvim-autopairs').setup({
ignored_next_char = "[%w%.]" -- will ignore alphanumeric and `.` symbol
})
```
``` text
Before Input After
------------------------------------
|foobar ( (|foobar
|.foobar ( (|.foobar
```
### Plugin Integration
``` lua
require('nvim-autopairs').disable()
require('nvim-autopairs').enable()
require('nvim-autopairs').remove_rule('(') -- remove rule (
require('nvim-autopairs').clear_rules() -- clear all rules
-- get rule " then modify it. It can return a list of rule or just a rule
require('nvim-autopairs').get_rule('"')
```
* Sample
```lua
-- remove add single quote on filetype scheme or lisp
require("nvim-autopairs").get_rule("'")[1].not_filetypes = { "scheme", "lisp" }
require("nvim-autopairs").get_rule("'")[1]:with_pair(cond.not_after_text("["}))
```
### FastWrap
``` text
Before Input After
--------------------------------------------------
(|foobar <M-e> then press $ (|foobar)
(|)(foobar) <M-e> then press q (|(foobar))
```
```lua
-- put this to setup function and press <a-e> to use fast_wrap
npairs.setup({
fast_wrap = {},
})
-- change default fast_wrap
npairs.setup({
fast_wrap = {
map = '<M-e>',
chars = { '{', '[', '(', '"', "'" },
pattern = [=[[%'%"%)%>%]%)%}%,]]=],
end_key = '$',
keys = 'qwertyuiopzxcvbnmasdfghjkl',
check_comma = true,
highlight = 'Search',
highlight_grey='Comment'
},
})
```
