How to set a config name without an extension

[raulb]

👋 ,

I'm having trouble understanding the necessary options to configure a file name without an extension (example: ~/.bashrc).

The error I'm having is exactly coming from https://github.com/gssbzn/viper/blob/717d682741fa3aeb6d3ce1a670e60b3908e71444/viper.go#L1429-L1431.

For context, I'm setting viper to write a file in the home directory:viper.AddConfigPath(home), and its name as viper.SetConfigName(".filename").

In #722, apparently the ability to write in files without an extension was added, and later in #827 this was only possible when config type was set. In my tests, for any valid config type, those end up being added to the file anyways. In other words, I haven't found a way create an extensionless file per the specs.

Any tips on how to accomplish this?

Thank you 🙏
