[](https://github.com/echasnovski/mini.nvim/blob/main/LICENSE) ### Autocompletion and signature help plugin - Async (with customizable 'debounce' delay) 'two-stage chain completion': first builtin LSP, then configurable fallback. - Has functionality for completion item info and function signature (both in floating window appearing after customizable delay). See more details in [Features](#features) and [help file](../doc/mini-completion.txt). --- ⦿ This is a part of [mini.nvim](https://github.com/echasnovski/mini.nvim) library. Please use [this link](https://github.com/echasnovski/mini.nvim/blob/main/readmes/mini-completion.md) if you want to mention this module. ⦿ All contributions (issues, pull requests, discussions, etc.) are done inside of 'mini.nvim'. ⦿ See the repository page to learn about common design principles and configuration recipes. --- If you want to help this project grow but don't know where to start, check out [contributing guides of 'mini.nvim'](https://github.com/echasnovski/mini.nvim/blob/main/CONTRIBUTING.md) or leave a Github star for 'mini.nvim' project and/or any its standalone Git repositories. ## Demo https://user-images.githubusercontent.com/24854248/173044355-90bfc230-70c4-4932-b66b-103284558994.mp4 ## Features - Two-stage chain completion: - First stage is an LSP completion. Supports `additionalTextEdits`, like auto-import and others. - If first stage is not set up or resulted into no candidates, fallback action is executed. The most tested actions are Neovim's built-in insert completion. - Automatic display in floating window of completion item info (via 'completionItem/resolve' request) and signature help (with highlighting of active parameter if LSP server provides such information). - Automatic actions are done after some configurable amount of delay. This reduces computational load and allows fast typing (completion and signature help) and item selection (item info) - User can force two-stage completion via or fallback completion. ## Installation This plugin can be installed as part of 'mini.nvim' library (**recommended**) or as a standalone Git repository. There are two branches to install from: - `main` (default, **recommended**) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled). - `stable` will be updated only upon releases with code tested during public beta-testing phase in `main` branch. Here are code snippets for some common installation methods (use only one):

**Important**: don't forget to call `require('mini.completion').setup()` to enable its functionality. **Note**: if you are on Windows, there might be problems with too long file paths (like `error: unable to create file : Filename too long`). Try doing one of the following: - Enable corresponding git global config value: `git config --system core.longpaths true`. Then try to reinstall. - Install plugin in other place with shorter path. ## Default config ```lua -- No need to copy this inside `setup()`. Will be used automatically. { -- Delay (debounce type, in ms) between certain Neovim event and action. -- This can be used to (virtually) disable certain automatic actions by -- setting very high delay time (like 10^7). delay = { completion = 100, info = 100, signature = 50 }, -- Configuration for action windows: -- - `height` and `width` are maximum dimensions. -- - `border` defines border (as in `nvim_open_win()`). window = { info = { height = 25, width = 80, border = 'none' }, signature = { height = 25, width = 80, border = 'none' }, }, -- Way of how module does LSP completion lsp_completion = { -- `source_func` should be one of 'completefunc' or 'omnifunc'. source_func = 'completefunc', -- `auto_setup` should be boolean indicating if LSP completion is set up -- on every `BufEnter` event. auto_setup = true, -- `process_items` should be a function which takes LSP -- 'textDocument/completion' response items and word to complete. Its -- output should be a table of the same nature as input items. The most -- common use-cases are custom filtering and sorting. You can use -- default `process_items` as `MiniCompletion.default_process_items()`. process_items = --, }, -- Fallback action. It will always be run in Insert mode. To use Neovim's -- built-in completion (see `:h ins-completion`), supply its mapping as -- string. Example: to use 'whole lines' completion, supply ''. fallback_action = --` completion>, -- Module mappings. Use `''` (empty string) to disable one. Some of them -- might conflict with system mappings. mappings = { force_twostep = '', -- Force two-step completion force_fallback = '', -- Force fallback completion }, -- Whether to set Vim's settings for better experience (modifies -- `shortmess` and `completeopt`) set_vim_settings = true, } ``` ## Similar plugins - [hrsh7th/nvim-cmp](https://github.com/hrsh7th/nvim-cmp) - [Shougo/ddc.vim](https://github.com/Shougo/ddc.vim)
