Neovim Configuration

Portable Neovim configuration using lazy.nvim and native LSP (Neovim 0.11+).

Installation

Standalone (any system)

git clone git@github.com:itme-brain/nvim.git ~/.config/nvim

As part of NixOS config

git clone --recurse-submodules git@github.com:itme-brain/nixos.git

Features

• Native LSP (vim.lsp.config) - no manual server list needed
• Smart LSP picker (<leader>css) - auto-detects installed servers for current filetype
• Portable - works on NixOS (LSPs via extraPackages) or any system (LSPs via Mason)
• Mason - auto-disabled on NixOS, auto-installs essentials elsewhere

LSP Setup

On NixOS, LSPs come from:

• neovim.extraPackages (global essentials)
• Project devShell (project-specific)

On other systems, Mason auto-installs:

• lua_ls - Lua/Neovim
• nil_ls - Nix
• bashls - Bash/Shell
• jsonls - JSON
• html - HTML
• cssls - CSS
• marksman - Markdown
• taplo - TOML
• yamlls - YAML

The smart picker (<leader>css) scans all lspconfig servers and shows only those with binaries installed.
