## nvim-autopairs
|
||||
|
||||
A minimalist autopairs for Neovim written by Lua.
|
||||
|
||||
Requires neovim 5.0+
|
||||
|
||||
``` lua
|
||||
require('nvim-autopairs').setup()
|
||||
|
||||
```
|
||||
## Default value
|
||||
|
||||
``` lua
|
||||
local charMap = { "'" , '"' , '{' , '[' , '(' , '`'}
|
||||
local charEndMap = { "'" , '"' , '}' , ']' , ')' , '`'}
|
||||
local disable_filetype = { "TelescopePrompt" }
|
||||
local break_line_filetype = {'javascript' , 'typescript' , 'typescriptreact' , 'go'}
|
||||
local html_break_line_filetype = {'html' , 'vue' , 'typescriptreact' , 'svelte' , 'javascriptreact'}
|
||||
|
||||
```
|
||||
|
||||
### override default value
|
||||
|
||||
``` lua
|
||||
require('nvim-autopairs').setup({
|
||||
disable_filetype = { "TelescopePrompt" , "vim" },
|
||||
})
|
||||
```
|
||||
|
||||
### Break line on html or inside pairs
|
||||
|
||||
By default nvim-autopairs don't mapping `<CR>` on insert mode
|
||||
if you want to do that you need to mapping it by your self
|
||||
|
||||
``` text
|
||||
Before Input After
|
||||
------------------------------------
|
||||
{|} <CR> {
|
||||
|
|
||||
}
|
||||
------------------------------------
|
||||
<div>|</div> <CR> <div>
|
||||
|
|
||||
</div>
|
||||
|
||||
```
|
||||
|
||||
## sample of mapping `<CR>`
|
||||
|
||||
``` lua
|
||||
-- this is my mapping with completion-nvim
|
||||
local remap = vim.api.nvim_set_keymap
|
||||
local npairs = require('nvim-autopairs')
|
||||
|
||||

|
||||
|
||||

|
||||
if vim.fn.pumvisible() ~= 0 then
|
||||
if vim.fn.complete_info()["selected"] ~= -1 then
|
||||
require'completion'.confirmCompletion()
|
||||
return npairs.esc("<c-y>")
|
||||
else
|
||||
vim.fn.nvim_select_popupmenu_item(0 , false , false ,{})
|
||||
require'completion'.confirmCompletion()
|
||||
return npairs.esc("<c-n><c-y>")

end

end

return npairs.esc("<cr>")
|
||||
end
|
||||
|
||||
remap('i' , '<CR>','v:lua.MUtils.completion_confirm()', {expr = true , noremap = true})
