exports from Yi.Config.Simple which are useful to "core yi" rather than just config files.

customVariable :: YiConfigVariable a => Field aSource
Accessor for any YiConfigVariable
, to be used by modules defining
YiConfigVariable
s. Such modules should provide a custom-named field.
For instance, take the following hypothetical YiConfigVariable
:
newtype UserName = UserName { unUserName :: String } deriving(Typeable, Binary, Initializable) instance YiConfigVariable UserName $(nameDeriveAccessors ''UserName (n -> Just (n ++ "A"))) userName ::Field
String
userName = unUserNameA.
customVariable
Here, the hypothetical library would provide the field userName
to be used in preference to customVariable
.
