autopairs.nvim

a simple neovim autopair plugin

installation

vim-plug

  Plug 'Sam-Programs/autopairs.nvim'
  lua << EOF
  require("autopairs").setup {}
  EOF

packer

use {
    "Sam-programs/autopairs.nvim",
    config = function() require("autopairs").setup {} end
}

setup

this is the default setup

require("autopairs").setup({
   wrapForwardKey = '<C-e>',
   wrapBackwradKey = '<C-a>',
   wordRegex = '%w',
   cmdline = true
   bracketList = {
      { '{',  '}' },
      { '(',  ')' },
      { '[',  ']' },
      { '\"', '\"' },
      { '\'', '\'' },
   },
})

features

the killer feature for this plugin is it never leaves insert mode so diagnostics and mode in lualine won't change Insert pair

{}-> {}

Delete pair

{|} -> |

word wrap + inverse wrap

<C-e>
(|)foo.bar -> (|foo).bar
(|foo).bar -> (|foo.bar)

<C-a>
(|foo.bar) -> (|foo).bar
(|)foo.bar -> (|foo).bar

Insert new indented line after Return

{|} -> {
           |
       }

Skip ' when the previous character is a letter

Ignore auto pair when the previous character is \

Very simple command line support

i didn't make a jump out of pair function becaues this does the job for me

vim.keymap.set("i", "<C-j>", "<down><end><cr>")

{
     |   C-j here
}
| and you go here

the formmating for Return uses cindenting if indentexpr is empty

this plugin doesn't have builtin cmp support because it's not that hard to impelement and i want you to create it your own customized autopairs for cmp

local kind = cmp.lsp.CompletionItemKind
-- auto add pairs
local function pair_on_confirm(event)
   local entry = event.entry
   local item = entry:get_completion_item()
   local keys = "()"
   local functionsig = item.label
   if item.kind == kind.Function or item.kind == kind.Method then
      -- auto skip empty functions
      if functionsig:sub(#functionsig - 1,#functionsig) ~= '()' then
         keys = keys .. '<left>'
         keys = vim.api.nvim_replace_termcodes(keys, true, false, true)
      end
      vim.api.nvim_feedkeys(keys, "n", false)
   end
end
cmp.event:on('confirm_done',pair_on_confirm) 

if u want to learn more about cmp read the types in its lua/cmp/types
