I'm not sure if you have taken a look at https://github.com/spf13/viper

• setting defaults
• reading from JSON, TOML, YAML, HCL, and Java properties config files
• live watching and re-reading of config files (optional)
• reading from environment variables
• reading from remote config systems (etcd or Consul), and watching changes
• reading from command line flags
• reading from buffer
• setting explicit values

As added bonus, Viper has the ability to bind to flags. Specifically, Viper supports Pflags as used in the Cobra library.

Yes, I know of it :) FYI I will not implement it in boilr, but if I choose to use cobra I will probably use Viper as well in my rewrite here: stancr
