Warning

Plugin moved to https://github.com/deathbeam/myplugins.nvim, all development will continue there

autocomplete.nvim

Very simple and minimal autocompletion for cmdline and buffer using LSP and Tree-sitter with signature help.

Originally I made this just for my dotfiles as I did not needed most of stuff existing plugins provided I had some issues with the ones that were close to what I wanted so as a learning exercise I decided to try and implement it by myself. Then I just extracted the code to separate plugin in case anyone else wanted to use it too. Just a warning, there might be some bugs and as this requires Neovim 0.10+ (e.g nightly), that one can also have bugs by itself.

Installation

Just use lazy.nvim or :h packages with git submodules or something else I don't care. Read the documentation of whatever you want to use.

Warning

cmd completion requires latest Neovim 0.11+ (e.g nightly)

Usage

Just require either buffer or cmd module or both and call setup on them.

Note

You dont need to provide the configuration, below is just default config, you can just call setup with no arguments for default.

-- LSP signature help
require("autocomplete.signature").setup {
    border = nil, -- Signature help border style
    width = 80, -- Max width of signature window
    height = 25, -- Max height of signature window
    debounce_delay = 100
}

-- buffer autocompletion with LSP and Tree-sitter
require("autocomplete.buffer").setup {
    border = nil, -- Documentation border style
    entry_mapper = nil, -- Custom completion entry mapper
    debounce_delay = 100,
}

-- cmdline autocompletion
require("autocomplete.cmd").setup()

You also probably want to enable popup in completeopt to show documentation preview:

vim.o.completeopt = 'menuone,noselect,noinsert,popup'

And you also ideally want to set the capabilities so Neovim will fetch documentation when resolving completion items:

-- Here we grab default Neovim capabilities and extend them with ones we want on top
local capabilities = vim.tbl_deep_extend('force', 
    vim.lsp.protocol.make_client_capabilities(), 
    require('autocomplete.capabilities')
)

-- Now set capabilities on your LSP servers
require('lspconfig')['<YOUR_LSP_SERVER>'].setup {
    capabilities = capabilities
}
