derive typeclass instances for decoding types from HOCON conf

confide

Build status

Confide port to Haskell (using GHC.Generics as opposed to Shapeless to generate FromConf typeclass instances). Uses deiko-config to parse HOCON .conf file and read in types

Usage

HOCON .conf file

a="hello"

b {
  y=true
  z {
    x=5
  }
}
