🚀 Neovim 0.12 Pure Native Configuration

A zero-framework, minimalist, and hyper-fast Neovim 0.12 configuration. This setup is the result of a complete migration from Neovim 0.11 and LazyVim, moving away from third-party abstraction layers in favor of pure native APIs.

✨ Highlights

• vim.pack Package Management: Leveraging the new built-in Neovim 0.12 plugin manager. No more lazy.nvim or packer.nvim overhead.
• Native LSP Configuration: Using the state-of-the-box declarative vim.lsp.config and vim.lsp.enable() patterns.
• Native Autocomplete: Powered by the new 0.12 'autocomplete' option for a "batteries-included" feel.
• Native Undo Tree: Persistent, visual undo history accessible via :Undotree.
• Decoupled Architecture: Every plugin has its own isolated configuration file in lua/plugins/. Clean, readable, and modular.
• Optimized for Swift/iOS: Full development support for Apple's ecosystem including sourcekit-lsp, Treesitter, and custom Swift-specific indentation.

🛠️ Tech Stack

• Fuzzy Finder: Telescope
• IDE Features: nvim-lspconfig, Mason, Conform, nvim-lint
• Syntax: nvim-treesitter (main branch; parsers compiled via the tree-sitter CLI)
• Others: Bufferline, Trouble, Dropbar, Molten

⚙️ Installation & Management

1. Clone: git clone https://github.com/your-username/nvim-config ~/.config/nvim
2. Bootstrap: Launch Neovim. The vim.pack manager will automatically detect and install all plugins on the first run.
3. Update Plugins: Run :lua vim.pack.update(). This will open a confirmation buffer; review the changes and run :w to apply the updates.
4. Restart: Use the new 0.12 :restart command to apply structural changes without quitting Neovim.

🧰 Troubleshooting

Treesitter parsers require the tree-sitter CLI

nvim-treesitter tracks its main branch (the rewrite). Two things differ from the old master branch:

• setup() no longer reads ensure_installed / auto_install / highlight / indent. Parsers are installed with require("nvim-treesitter").install{...} and highlighting is turned on per-buffer with vim.treesitter.start() (both handled in lua/plugins/treesitter.lua).

• Parsers are compiled from source, so the tree-sitter CLI must be on PATH. On macOS the CLI is a separate Homebrew formula from the library:

  brew install tree-sitter-cli   # NOT `tree-sitter`, which is library-only

If you see nvim-treesitter parser missing <lang> or files open with no syntax highlighting, install the CLI, then run :lua require("nvim-treesitter").install{ "typescript", ... } (or just reopen Neovim; missing parsers install on startup).

Trouble <leader>cS says "No results for lsp"

Two independent causes, both handled in the current config:

• Server not attached yet. The LSP keymaps wait for LspAttach before opening Trouble, so firing on a freshly-opened buffer no longer fails silently.
• Cursor sitting on a symbol whose only location is the current line (e.g. an interface property whose definition equals its single reference). Trouble hides current-line results by default; this config sets include_current = true on the lsp mode so those symbols still show. Cursor-follow speed is controlled by updatetime (set to 250 in lua/config/options.lua).
