Explicit representation of Haskell datatype information

data HType Source

A concrete representation of any Haskell type.

Constructors

Maybe HType 
List HType 
Tuple [HType] 
Prim String String

separate Haskell name and XML name

String 
Defined String [HType] [Constr]

A user-defined type has a name, a sequence of type variables, and a set of constructors. (The variables might already be instantiated to actual types.)

Instances

data Constr Source

A concrete representation of any user-defined Haskell constructor. The constructor has a name, and a sequence of component types. The first sequence of types represents the minimum set of free type variables occurring in the (second) list of real component types. If there are fieldnames, they are contained in the final list, and correspond one-to-one with the component types.

Constructors

Constr String [HType] [HType] 

Instances

Helper functions to extract type info as strings

showHType :: HType -> ShowS Source

showConstr :: Int -> HType -> String Source

Project the n'th constructor from an HType and convert it to a string suitable for an XML tagname.

Conversion from Haskell datatype to DTD

toDTD :: HType -> DocTypeDecl Source

toDTD converts a concrete representation of the Haskell type of a value (obtained by the method toHType) into a real DocTypeDecl. It ensures that PERefs are defined before they are used, and that no element or attribute-list is declared more than once.
