Go JSON/v2 Package

Re:Go JSON/v2 Package by sureglymop on Saturday October 07, 2023 @03:07AM (#37799661)

Does anyone know if there is a good "config validation" package in go? I want to read in a json config file from the user, validate it with a schema that even checks for missing keys or keys that shouldn't be in the file, then if there are errors I want to print to the user the exact line of the file that is the problem. The assumption is that the user will misconfigure something and should thus be informed.

validator has worked well for me, but it doesn't operate on files, rather it validates the structs after unmarshaling.

I am using validator now and it's okay. I did have to write some custom validators and it wasn't too well documented. Unfortunately it's a bit hard to generate the right error messages for the user to see exactly where the misconfiguration is.
