Readme!
====================

1. There is a GitHub issue that documents [breaking changes](https://github.com/hrsh7th/nvim-cmp/issues/231) for nvim-cmp. Subscribe to the issue to be notified of upcoming breaking changes.
2. This is my hobby project. You can support me via GitHub sponsors.
3. Bug reports are welcome, but don't expect a fix unless you provide minimal configuration and steps to reproduce your issue.
4. The `cmp.mapping.preset.*` is pre-defined configuration that aims to mimic neovim's native like behavior. It can be changed without announcement. Please manage key-mapping by yourself.

Concept
====================

- Full support for LSP completion related capabilities
- Powerful customizability via Lua functions
- Smart handling of key mappings
- No flicker


Setup
====================

### Recommended Configuration

This example configuration uses `vim-plug` as the plugin manager and `vim-vsnip` as a snippet plugin.

Plug 'hrsh7th/cmp-buffer'
Plug 'hrsh7th/cmp-path'
Plug 'hrsh7th/cmp-cmdline'
Plug 'hrsh7th/nvim-cmp'

Plug 'hrsh7th/cmp-vsnip'
Plug 'hrsh7th/vim-vsnip'

" For luasnip users.
" Plug 'L3MON4D3/LuaSnip'
