# 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. There really isn't a reason to have this in a plugin other than wanting to disseminate it for new users or people who didn't know you could do this. You could (should) instead just yank and put the code right in your configuration.
