ini VS kelseyhightower/envconfig

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.

To configure the app I'd take a look at https://github.com/kelseyhightower/envconfig

envconfig

- Having one way of configuring the app is excellent. You can either prefer environment variables, a file, or flags. You can do what Viper does by reading the file and unmarshalling it. The built-in flag package is enough for your flag-based config needs. If you want to prefer environment variables, I prefer https://github.com/kelseyhightower/envconfig

To extract values from the system environment, I utilize envconfig, a Go package. Envconfig facilitates mapping system environment variables to a Go struct. These Go structs are exposed through a config package, enabling other parts of the application to access them.

You could prefix your env vars and use this package. https://github.com/kelseyhightower/envconfig

kelseyhightower/envconfig

Pretty much all of our services and pkgs use https://github.com/kelseyhightower/envconfig. It’s dead simple, gets out of your way, and is battle tested
