# retrail.nvim

Retrail is a small Neovim plugin for managing trailing whitespace. It has two

main features:

1. Highlight trailing whitespace.

1. Trim trailing whitespace upon `:write`.

## Installation

Install this plugin using your favorite plugin manager. For example, using

[lazy]:

```lua

{

  "kaplanz/retrail.nvim",

  opts = {}, -- calls `setup` using provided `opts`

},

```

To manually set up the plugin, call the `setup` function:

```lua

require("retrail").setup()

```

## Configuration

While the [defaults] should work for most users out of the box, the following

options can be configured as such:

```lua

require("retrail").setup {

  -- Highlight group to use for trailing whitespace.

  hlgroup = "Search",

  -- Pattern to match trailing whitespace against. Edit with caution!

  pattern = "\\v((.*%#)@!|%#)\\s+$",

  -- Enabled filetypes.

  filetype = {

    -- Strictly enable only on `include`ed filetypes. When false, only disabled

    -- on an `exclude`ed filetype.

    strict = false,

    -- Included filetype list.

    include = {},

    -- Excluded filetype list. Overrides `include` list.

    exclude = {

      "",

      "aerial",

      "alpha",

      "checkhealth",

      "cmp_menu",

      "diff",

      "lazy",

      "lspinfo",

      "man",

      "mason",

      "TelescopePrompt",

      "toggleterm",

      "Trouble",

      "WhichKey",

    },

  },

  -- Enabled buftypes.

  buftype = {

    -- Strictly enable only on `include`ed buftypes. When false, only disabled

    -- on an `exclude`ed buftype.

    strict = false,

    -- Included buftype list.

    include = {},

    -- Excluded buftype list. Overrides `include` list.

    exclude = {

      "help",

      "nofile",

      "prompt",

      "quickfix",

      "terminal",

    }

  },

  -- Trim on write behaviour.

  trim = {

    -- Auto trim on BufWritePre

    auto = true,

    -- Trailing whitespace as highlighted.

    whitespace = true,

    -- Final blank (i.e. whitespace only) lines.

    blanklines = false,

  }

}

```

## Commands
