genUniverseBi #

Arguments

:: Name	function of type `S -> [T]`
-> Q Exp

Generate TH code for a function that extracts all subparts of a certain type. The argument to genUniverseBi is a name with the type S -> [T], for some types S and T. The function will extract all subparts of type T from S.

genUniverseBi' :: TypeQ -> Q Exp #

genUniverseBiT #

Arguments

:: [TypeQ]	types not touched by `universeBi`
-> Name	function of type `S -> [T]`
-> Q Exp

Same as genUniverseBi, but does not look inside any types mention in the list of types.

genUniverseBiT' :: [TypeQ] -> TypeQ -> Q Exp #

genTransformBi #

Arguments

:: Name	function of type `(S->S) -> T -> T`
-> Q Exp

Generate TH code for a function that transforms all subparts of a certain type. The argument to genTransformBi is a name with the type (S->S) -> T -> T, for some types S and T. The function will transform all subparts of type S inside T using the given function.

genTransformBi' :: TypeQ -> Q Exp #

genTransformBiT :: [TypeQ] -> Name -> Q Exp #

Same as genTransformBi, but does not look inside any types mention in the list of types.

genTransformBiT' :: [TypeQ] -> TypeQ -> Q Exp #

genTransformBiM :: Name -> Q Exp #

genTransformBiM' :: TypeQ -> Q Exp #

genTransformBiMT :: [TypeQ] -> Name -> Q Exp #

genTransformBiMT' :: [TypeQ] -> TypeQ -> Q Exp #
