Putting " \ " in the config.jsonc will crash waybar in any module or module name or format types etc.

Waybar v0.11.0

To reproduce, add a \ into any part of the config that is uncommented, does not matter if module with \ is called or not, if its just a name or part of the formatting output

I wouldn't call that a crash. Waybar doesn't start because the config file is invalid that way. Not starting when the config is not valid sounds entirely sensible to me.

Outside of strings, \ is not a valid character in json, and inside of strings, \ starts an escape sequence in json. If you want to use \ in a string in json, you have to escape it like \\.

See
https://datatracker.ietf.org/doc/html/rfc8259
https://ecma-international.org/publications-and-standards/standards/ecma-404/
for details. Jsonc is a superset of json, so the same considerations apply to it.

I don't think there's a bug here.

Oh, yea I would agree. I have only used jsonc for waybar so I had no idea, thanks for the help!
