Neovim 0.11 LSP + Blink-cmp Setup Guide

This guide provides a complete configuration for setting up Neovim 0.11 with blink-cmp and LSP using lazy.nvim.

Key Features of Neovim 0.11

• Built-in vim.lsp.config: No need for nvim-lspconfig on 0.11+
• Built-in vim.lsp.enable(): Simplified LSP server activation
• Better default keymaps: Many LSP keybindings work out of the box
• Simplified blink-cmp integration: Automatic capability detection

Setup Overview

1. blink-cmp: Modern completion engine with LSP, snippets, path, and buffer sources
2. mason.nvim: LSP server installer/manager
3. LSP Configuration: Using Neovim 0.11's built-in vim.lsp.config and vim.lsp.enable()

File Structure

~/.config/nvim/
├── lua/
│   └── kiyo/
│       └── plugins/
│           ├── blink.lua        # Blink-cmp configuration
│           ├── mason.lua        # Mason LSP installer
│           └── lsp.lua          # LSP configuration
└── init.lua

Installation Steps

1. Copy the configuration files to your Neovim config directory
2. Restart Neovim
3. Lazy.nvim will automatically install plugins
4. Mason will install LSP servers specified in ensure_installed

Important Notes

Warning

On Neovim 0.11+, you do NOT need to manually set LSP capabilities when using vim.lsp.config. Blink-cmp capabilities are automatically detected.

Tip

If you want to see inline error messages (virtual text), it's now disabled by default in Neovim 0.11. Enable it with:

vim.diagnostic.config({ virtual_text = true })

Important

The keymap.preset in blink-cmp has several options:

• 'default': C-y to accept (recommended, similar to built-in)
• 'super-tab': Tab to accept (VSCode-like)
• 'enter': Enter to accept
• 'none': No default mappings

Default LSP Keybindings (Neovim 0.11)

These work automatically when LSP is attached:

• gd - Go to definition
• gD - Go to declaration
• gr - Go to references
• K - Hover documentation
• <C-k> - Signature help (in insert mode)
• <space>rn - Rename
• <space>ca - Code action
• <space>f - Format

Configured Language Servers

The example includes:

• TypeScript/JavaScript: ts_ls
• HTML: html
• CSS: cssls
• Lua: lua_ls
• Python: pyright
• Go: gopls
• Rust: rust_analyzer

Add or remove servers in mason.lua and lsp.lua as needed.
