Is there a way to not remove whitespace at the end of file?

[computersarecool]

I actually like the extra new line at the end of the file. Is there a way not to remove it?

[lewang]

Not currently. What's the usecase?

I have been told it is good practice

Have you consulted the documentation for require-final-newline?

[computersarecool]

Yes and I currently have it set to t which means it should add a new line when the file is about to be saved. Unfortunately it looks like butler removes the newline after this.

Ok, that's a bug then. I'll take a closer look when I get a chance.

Thanks

It looks like you have code here specifically trying to avoid this but it is removing the newline on my files.

Can you give repro steps from emacs -Q? I just saved a file that had require-final-newline set to t and the final newline was added.

Steps to reproduce:

Start emacs -Q
Install ws-butler
Visit file testing.js
Enable linum-mode (to see line numbers)
Enable ws-butler-mode

Type const http = require('http') followed by 3 new lines
On line 2 type console.log(http)
Type C-x C-s

File will be truncated to two lines
wc -l testing.js = 2
