🌿 Jump to symbols in your code with live preview, built-in fuzzy finding, and other modules. Inspired by Zed, it preserves symbol order while guiding you through your codebase.
“Namu” means “tree🌳” in Korean—just like how it helps you navigate the structure of your code.
Warning
🚧 Beta Status: This plugin is currently in beta. While it's functional, you may encounter breaking changes as we improve and refine the architecture. Your feedback and contributions are welcome!
namu_showcase.mp4
- 🔍 Live Preview: See exactly where you'll land before you jump
- 🌳 Order Preservation: Maintains symbol order as they appear in your code, even after filtering
- 📐 Smart Auto-resize: Window adapts to your content in real-time as you type and filter, no need for a big window with only a couple of items
- 🚀 Zero Dependencies: Works with any LSP-supported language out of the box
- 🎯 Context Aware: Always shows your current location in the codebase
- 🌑 Initially Hidden Mode: Start with an empty list and populate it dynamically as you type, just like the command palette in Zed and VS Code
- ⚡ Powerful Filtering:
- Built-in fuzzy finding that understands code structure
- Filter by symbol types (functions, classes, methods)
- Use regex patterns (e.g.,
^__to filter out Python's__init__methods)
- 🎨 Quality of Life:
- Auto-select when only one match remains
- Remembers cursor position when you cancel
- Customizable window style and behavior
- ✂️ Multi-Action Workflow: Perform multiple operations while Namu is open (or close it after, you choose!):
- Delete, yank, and add to CodeCompanion chat (more plugins coming soon)
- Works with both single and multiple selected symbols
Namu is powered by Selecta, a minimal and flexible fuzzy finder that's also used by:
- 🎨 Colorscheme Picker: Live preview with your code and switch themes with persistence
- 🔄 vim.ui.select: Enhanced wrapper for Vim's built-in selector
- 📦 More modules coming soon, including buffers and diagnostics!
- Neovim >= 0.10.0
- Configured LSP server for your language (Treesitter fallback coming soon)
- Treesitter (for live preview functionality)

- colorscheme: Select and apply a colorscheme.
- help: Display help for all commands.
To use the Namu command, enter the following in command mode:

}- Type to filter symbols - it's fuzzy, so no need to be exact, though it prioritizes exact words first
- Use regex patterns for precise filtering (e.g.,
^test_for test functions) - Press
<CR>to jump,<Esc>to cancel
🌳 Order Preservation
Maintains symbol order as they appear in your code, even after filteringpreserve_order.mp4
🌑 Initially Hidden Mode
Start with an empty list and populate it dynamically as you type, just like the command palette in Zed and VS Codeinitinally_hidden.mp4
🔍 Live Preview & Context Aware
focus on the current location in the codebase when open so you know where you are in the codelive_preview.mp4
⚡ Auto-select
if only one match remains, automatically select it. In the video I didn't press enter, yet the jump was done automatically.auto_select.mp4
I made this plugin for fun at first and didn't know I could replicate what Zed has, and to be independent and free from any pickers. Pull requests are welcome! Just please be kind and respectful. Any suggestions to improve and integrate with other plugins are also welcome.
- Zed editor for the idea.
- Mini.pick @echasnovski for the idea of
getchar(), without which this plugin wouldn't exist. - Magnet module (couldn’t find it anymore on GitHub, sorry!), which intrigued me a lot.
- @folke for handling multiple versions of Neovim LSP requests in Snacks.nvim.
- tests and ci structure, thanks to @Oli CodeCompanion
- A simple mechanism to persist the colorscheme, thanks to this Reddit comment.
