viper VS ini

The code uses Viper to load configuration files in the application.

github.com/spf13/viper

Instead of directly accessing environment variables with os.Getenv(), integrating a configuration handler like viper might make it maintainable.

I guess most people are using https://github.com/spf13/viper but I don't know if I should read everything from

Use Viper for config file or environmental variable configuration -- it's going to save you a whole lot of time.

Cobra and Viper.

I've mostly been using https://github.com/spf13/viper of late for my go projects. It supports the standard config formats, (json, yaml, toml etc) and lets you override any value with a ENV value.

Not only that, the "unmarshall to struct" method doesn't work at all for environment variables. https://github.com/spf13/viper/issues/188

I am very new to golang and am trying to write a Program that uses INI Cobfiguration Files. The library that I am using, has built in functions to output the Key as a certain type (string, int, bool, etc). However as I will be accessing several different Keys of different types, I wrote a wrapper that takes the section and key name and the output type, passes that to the libraries functions and outputs the result as the any type. While trying to pass the output into another function that requires a string, it throws the error that it is unable to convert any to string as string requires type assertion. I couldn't find much about the any type, but it seems luke i will either need to redesign my wrapper function, use an alternative to any or find a way to convert any to string or []byte at least.
