[back to package description]

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
  }
}

{-# LANGUAGE OverloadedStrings #-}
{-# LANGUAGE TypeApplications #-}

module Test where

import Data.Confide
import Data.Confide.Generic
import qualified Data.Text as T

data Foo = Foo {x :: Integer} deriving (Generic, Show)
data Bar = Bar {y :: Bool, z :: Foo} deriving (Generic, Show)
data Baz = Baz {a :: T.Text, b :: Bar} deriving (Generic, Show)

instance FromConf Foo
instance FromConf Bar
instance FromConf Baz

main :: IO ()
main = do
  c <- loadConfig "project/path/to/confFile.conf"
  baz <- get @Baz "" c
  print baz

GHCI

$ main 
Baz {a = "hello", b = Bar {y = True, z = Foo {x = 5}}}
