# tidy.nvim 🧹

|
|
An [autocommand](https://neovim.io/doc/user/autocmd.html) that removes all
|
|
|
|
- trailing whitespace
|
|
- empty lines at the end of the buffer
|
|
|
|
on every `BufWritePre`.

## About
|
|
I originally wrote this as a wrapper around a couple of vim regex commands used for formatting files before I began using formatters. These commands are not mine, please see the `Credits` section below for sources. Even with real formatters in my setup now, I still like and use this because I like these specific formats to be applied to every buffer and don't want to have a formatting tool installed for them.

## Installation
|
|
- [packer.nvim](https://github.com/wbthomason/packer.nvim)
|
|
|
|
```lua
|
|
use({
|
|
"mcauley-penney/tidy.nvim",
|
|
config = function()
|
|
require("tidy").setup()
|
|
end
|
|
})
|
|
```
|
|
|
|
## Configuration
|
|
Tidy will work on all buffers using only the basic installation shown above. No configuration options are required. The options displayed below are simply examples.
|
|
|
|
```lua
|
|
require("tidy").setup({
|
|
filetype_exclude = { "markdown", "python" },
|
|
})
|
