# jj-mini.diff

A Neovim plugin to provide `mini.diff`-like functionality for Jujutsu (`jj`) repositories, with a focus on displaying Git signs for changes.

## Features

*   **Jujutsu Git Signs:** Visually indicate added, modified, and deleted lines directly in your Neovim buffer, reflecting changes in your `jj` working copy.
*   **Seamless Integration:** Designed to integrate smoothly with Neovim's existing `diff` capabilities and user interface.

## Installation

You can install `jj-mini.diff` using your favorite Neovim plugin manager.

**lazy.nvim:**

```lua
{
  "your-github-username/jj-mini.diff", -- Replace with the actual repository path
  config = function()
    require("jj_mini_diff").setup({
      -- Your configuration options here
    })
  end,
}
```

## Usage

To activate the plugin, call the `setup()` function in your Neovim configuration:

```lua
require("jj_mini_diff").setup({
  -- Optional: Customize signs or autocmd events
  -- signs = {
  --   add = { text = "++", texthl = "DiffAdd", numhl = "DiffAdd" },
  --   change = { text = "//", texthl = "DiffChange", numhl = "DiffChange" },
  --   delete = { text = "--", texthl = "DiffDelete", numhl = "DiffDelete" },
  -- },
  -- autocmd_events = { "BufReadPost", "BufWritePost", "CursorHold", "InsertLeave" },
})
```

The plugin will automatically place and update signs in files within a Jujutsu repository on `BufReadPost`, `BufWritePost`, and `CursorHold` events by default.

You can also manually refresh the signs for the current buffer at any time:

```lua
:lua require("jj_mini_diff").refresh_signs()
```

## Configuration

The `setup()` function accepts an optional table for configuration.

```lua
require("jj_mini_diff").setup({
  signs = {
    add = { text = "│", texthl = "JjDiffAdd", numhl = "JjDiffAdd" },
    change = { text = "│", texthl = "JjDiffChange", numhl = "JjDiffChange" },
    delete = { text = "─", texthl = "JjDiffDelete", numhl = "JjDiffDelete" },
  },
  autocmd_events = { "BufReadPost", "BufWritePost", "CursorHold" },
})
```

*   **`signs`**: A table to customize the text, text highlight group (`texthl`), and number highlight group (`numhl`) for each sign type.
    *   `add`: For added lines.
    *   `change`: For changed lines.
    *   `delete`: For deleted lines.
*   **`autocmd_events`**: A list of Neovim autocommand events that will trigger a sign refresh.
