tiny-lightbulb.nvim
A tiny lightbulb for Neovim 0.12+. Shows a sign when LSP code actions are available on the current line.
Zero config. ~40 lines of Lua.
Features
- Displays a 💡 in the sign column when code actions are available
- Clears instantly on cursor move
- Async LSP requests with stale-response handling
- Configurable sign text and highlight group
- Works out of the box — no setup call required
Requirements
- Neovim >= 0.12
- At least one LSP server that supports code actions
Installation
Add to your vim.pack.add() call:
"https://github.com/swaits/tiny-lightbulb.nvim",
Done. The plugin auto-loads with sensible defaults.
Configuration
All options are optional. Call setup() only if you want to customize:
require("tiny-lightbulb").setup({
sign = "💡", -- sign column text
hl = "DiagnosticWarn", -- highlight group
})
How it works
On CursorHold, the plugin asks all attached LSP clients whether code
actions exist for the current line. If any are returned, an extmark sign
is placed. On CursorMoved, the sign is cleared and any in-flight LSP
responses are discarded via a generation counter.
