Toml.Generic

This module makes it possible to easily derive the TOML classes using the DerivingVia extension.

For example:

data Physical = Physical {
    color :: String,
    shape :: String
    }
    deriving (Eq, Show, Generic)
    deriving (ToTable, ToValue, FromValue) via GenericTomlTable Physical

These derived instances would allow you to match TOML {color="red", shape="round"} to value Coord 1 2.

data Coord = Coord Int Int
    deriving (Eq, Show, Generic)
    deriving (ToValue, FromValue) via GenericTomlArray Physical

These derived instances would allow you to match TOML [1,2] to value Coord 1 2.
