Wow, that was really fast. Thanks 😃

I think this slightly changes (in a backwards incompatible way) how config files are loaded.

Before, if $XDG_CONFIG_HOME/polybar/config didn't exist (but the env variable did), it would try $HOME/.config/polybar/config, now the function directly returns an empty string.

Please also add these changes to the changelog (https://github.com/polybar/polybar/blob/master/CONTRIBUTING.md#changelog)

These changes also need to be reflected in doc/man/polybar.5.rst, in the first section.

Ah I see what you mean. It looks like I might've went wrong there when refactoring the code. I will go ahead and fix this

Sorry, I forgot to do that 😅. I will upload the changes shortly.

Awesome. Looks like it works now :)

Please remove the extra newlines in CHANGELOG.md again and I'll merge this.

[patrick96]

The lack of newlines was intentional because that's also how keep a changelog does it. Please remove them again.

[kamui-fin]

Sorry about that, my IDE most likely auto formatted it

[patrick96]

Yeah, I thought as much ;)

[patrick96]

Looks good now. Thanks a lot 🚀
