It's a Fast and Minimalism Style Completion Plugin for vim/nvim.
Vim-easycomplete is a fast and minimalism style completion plugin for both vim and nvim. It aims to be available out of the box on linux and mac. It is implemented in pure VimScript and is extremely simple to configure without installing Node and a bunch of Node modules. Thank nvim-cmp and coc.nvim. They inspired me a lot.

It contains these features:
- Full lsp support. Easy to install LSP Server with one command
- Keywords/Directory support
- Implemented based on pure vimscript
- Snippet support via Snippets.
- Fast performance
- AI coding assistant via tabnine.
Requires Vim 8.2 or higher version on MacOS/Linux/FreeBSD. Neovim 0.6.0 or higher.
Lua config with Packer.nvim:
use { 'jayli/vim-easycomplete', requires = {'SirVer/ultisnips'}}
-- Tabnine aicoding support, default is 1
-- You should install tabnine first by ":InstallLspServer tabnine"
vim.g.easycomplete_tabnine_enable = 1
-- Tabnine coding suggestion, default is 0
vim.g.easycomplete_tabnine_suggestion = 0
-- Using nerdfont for lsp icons, default is 0
vim.g.easycomplete_nerd_font = 1
-- Add window border for pum, default is 1 (for nvim 0.11 or higher)
vim.g.easycomplete_winborder = 1
-- Pmenu format, default is {"abbr", "kind", "menu"}
vim.g.easycomplete_pum_format = {"kind", "abbr", "menu"}
-- Useful keymap
vim.keymap.set('n', 'gr', ':EasyCompleteReference<CR>')
vim.keymap.set('n', 'gd', ':EasyCompleteGotoDefinition<CR>')
vim.keymap.set('n', 'rn', ':EasyCompleteRename<CR>')
vim.keymap.set('n', 'gb', ':BackToOriginalBuffer<CR>')
Run :PackerInstall
Vimscript config with vim-plug:
Plug 'jayli/vim-easycomplete'
Plug 'SirVer/ultisnips'

- Go: gopls required. (
go get golang.org/x/tools/gopls) - Vim Script: vimls required.

You can add filetypes whitelist for specified language plugin. In most cases, it is not necessary to do so:
let g:easycomplete_filetypes = {
\ "sh": {
\ "whitelist": ["shell"]
\ },
\ "r": {
\ "whitelist": ["rmd", "rmarkdown"]
\ },
\ }Vim-EasyComplete does not integration snippets by default. If you want snippet support, please install ultisnips. UltiSnips is compatible with Vim-EasyComplete. UltiSnips required python3 installed.
Solution of "E319: No python3 provider found" Error in neovim 0.4.4 with ultisnips
In addition to associating AI matching words in the complete menu, there are multiple options for AI coding suggestions.
Vim-easycomplete integrates Tabnine built-in.Install TabNine: :InstallLspServer tabnine. Then restart your vim/nvim.
You can config TabNine by g:easycomplete_tabnine_config witch contains two properties:
- line_limit: The number of lines before and after the cursor to send to TabNine. If the option is smaller, the performance may be improved. (default: 1000)
- max_num_result: Max results from TabNine showing in the complete menu. (default: 3)
let g:easycomplete_tabnine_config = {
\ 'line_limit': 1000,
\ 'max_num_result' : 3,
\ }TabNine works well without APIKey. If you have a Tabnine's Pro API key or purchased a subscription license. To configure, you'll need to use the TabNine' magic string. Type Tabnine::config in insert mode to open the configuration panel.
Enable TabNine inline suggestion: let g:easycomplete_tabnine_suggestion = 1.
Vim-easycomplete is working well with deepseek-coder.nvim.
If you are an Alibaba engineer, then Aone-copilot is the best choice.
Set g:easycomplete_nerd_font = 1 to enable default nerdfonts configuration.
If you want to customize the kind icon, you can modify the configuration with https://nerdfonts.com installed. Examples.
You can add custom Pmenu styles by defining these highlight groups:
EasyFuzzyMatch: highlight fuzzy matching character. It links to "Constant" by default if it's not defined.EasyPmenu: Pmenu style. It links to "Pmenu" by default.EasyPmenuKind: PmenuKind style. It links to "PmenuKind" by default.EasyPmenuExtra: PmenuExtra style. It links to "PmenuExtra" by default.EasyFunction: Function kind icon style. links to "Conditional" by default.EasySnippet: Snippet kind icon style. links to "Keyword" by default.EasyTabNine: TabNine kind icon style. links to "Character" by default.EasySnippets: TabNine snippets suggestion style. links to "LineNr" by default
When g:easycomplete_winborder is set to 1. The guibg of Pmenu will be set to be the same as the Normal guibg.
