# nvim-cmp



A completion engine plugin for neovim written in Lua.

Completion sources are installed from external repositories and "sourced".

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.



```lua

call plug#begin(s:plug_dir)

Plug 'neovim/nvim-lspconfig'

Plug 'hrsh7th/cmp-nvim-lsp'

Plug 'hrsh7th/cmp-buffer'

Plug 'hrsh7th/cmp-path'

Plug 'hrsh7th/cmp-cmdline'

Plug 'hrsh7th/nvim-cmp'



" For vsnip users.

Plug 'hrsh7th/cmp-vsnip'

Plug 'hrsh7th/vim-vsnip'



" For luasnip users.

" Plug 'L3MON4D3/LuaSnip'

" Plug 'saadparwaiz1/cmp_luasnip'



" For ultisnips users.

" Plug 'SirVer/ultisnips'

" Plug 'quangnguyen30192/cmp-nvim-ultisnips'



" For snippy users.

" Plug 'dcampos/nvim-snippy'

" Plug 'dcampos/cmp-snippy'



call plug#end()



lua <'] = cmp.mapping.scroll_docs(-4),

      [''] = cmp.mapping.scroll_docs(4),

      [''] = cmp.mapping.complete(),

      [''] = cmp.mapping.abort(),

      [''] = cmp.mapping.confirm({ select = true }), -- Accept currently selected item. Set `select` to `false` to only confirm explicitly selected items.

    }),

    sources = cmp.config.sources({

      { name = 'nvim_lsp' },

      { name = 'vsnip' }, -- For vsnip users.

      -- { name = 'luasnip' }, -- For luasnip users.

      -- { name = 'ultisnips' }, -- For ultisnips users.

      -- { name = 'snippy' }, -- For snippy users.

    }, {

      { name = 'buffer' },

    })

  })



  -- Set configuration for specific filetype.

  cmp.setup.filetype('gitcommit', {

    sources = cmp.config.sources({

      { name = 'git' }, -- You can specify the `git` source if [you were installed it](https://github.com/petertriho/cmp-git).

    }, {

      { name = 'buffer' },

    })

  })



  -- Use buffer source for `/` and `?` (if you enabled `native_menu`, this won't work anymore).

  cmp.setup.cmdline({ '/', '?' }, {

    mapping = cmp.mapping.preset.cmdline(),

    sources = {

      { name = 'buffer' }

    }

  })



  -- Use cmdline & path source for ':' (if you enabled `native_menu`, this won't work anymore).

  cmp.setup.cmdline(':', {

    mapping = cmp.mapping.preset.cmdline(),

    sources = cmp.config.sources({

      { name = 'path' }

    }, {

      { name = 'cmdline' }

    }),

    matching = { disallow_symbol_nonprefix_matching = false }

  })



  -- Set up lspconfig.

  local capabilities = require('cmp_nvim_lsp').default_capabilities()

  -- Replace  with each lsp server you've enabled.

  require('lspconfig')[''].setup {

    capabilities = capabilities

  }

EOF

```
