On save trailing whitespace is removed

[JohnVillalovos]

When I save a file (in this case a PHP file) the trailing whitespace is being removed. Which I'm a fan of, but I am working on a preexisting code base and this is generating a lot of unrelated changes when submitting PRs.

I'm not sure which plugin or setting is causing this but I would like to be able to turn it off.

Thanks!

Did you enable php LSP? In that case it's probably the conform plugin auto-format-on-save. You can try adding php on the disable list by making this change:

diff --git a/init.lua b/init.lua
index 88658ef..f7cb136 100644
--- a/init.lua
+++ b/init.lua

@dam9000 Thanks. I should have mentioned that I had already completely commented out the conform section as that really messed things up for doing PRs.

So something else is removing the trailing whitespace.

Sounds like it might be caused by the editorconfig integration https://neovim.io/doc/user/editorconfig.html. you might want to disable the trim_trailing_whitespace option

Woo hoo! That was it! Thanks!

So the project I was doing a PR for has a .editorconfig in the repo that has trim_trailing_whitespace set. But they don't seem to have trimmed the whitespace yet on a lot of the files ☹️

When I uncommented the line in .editorconfig it stopped removing the trailing whitespace.

I'll go ahead and close this.
