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:
lazy.nvim
return {
'windwp/nvim-autopairs',
event = "InsertEnter",
opts = {} -- this is equalent to setup({}) function
}vim-plug
Plug 'windwp/nvim-autopairs'
lua << EOF
require("nvim-autopairs").setup {}
EOFpacker
use {
"windwp/nvim-autopairs",
config = function() require("nvim-autopairs").setup {} end
}Default values
local disable_filetype = { "TelescopePrompt", "spectre_panel" }
local disable_in_macro = true -- 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
require('nvim-autopairs').setup({
disable_filetype = { "TelescopePrompt" , "vim" },
})Mapping <CR>

nvim-cmp
You need to add mapping `CR` on nvim-cmp setup. Check readme.md on nvim-cmp repo.
-- 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.
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 table item completion
---@param bufnr number buffer number
---@param rules table
---@param commit_character table<string>
handler = function(char, item, bufnr, rules, commit_character)
-- Your handler function. Inpect with print(vim.inspect{char, item, bufnr, rules, commit_character})
end
}
},
-- Disable for tex
tex = false
}
})
)Don't use nil to disable a filetype. If a filetype is nil then * is used as fallback.

local npairs = require('nvim-autopairs')
npairs.setup({ map_bs = false, map_cr = false })

end
end
remap('i', '<bs>', 'v:lua.MUtils.BS()', { expr = true, noremap = true })without completion plugin
-- add option map_cr
npairs.setup({ map_cr = true })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.
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
Treesitter
You can use treesitter to check for a pair.
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
Before Input After
------------------------------------
( |)) ( ( (|))
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
require('nvim-autopairs').setup({
ignored_next_char = "[%w%.]" -- will ignore alphanumeric and `.` symbol
})Before Input After
