# 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. ~50 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, highlight, and priority
- 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:

```lua
"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:

```lua
require("tiny-lightbulb").setup({
  sign = "💡",           -- sign column text
  hl = "DiagnosticWarn",  -- highlight group
  priority = 10,          -- extmark priority
})
```

## 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.
