A suite of datatypes describing the (semi-concrete) abstract syntax of Haskell 98 http://www.haskell.org/onlinereport/ plus registered extensions, including:
- multi-parameter type classes with functional dependencies (MultiParamTypeClasses, FunctionalDependencies)
- parameters of type class assertions are unrestricted (FlexibleContexts)
forall
types as universal and existential quantification (RankNTypes, ExistentialQuantification, etc)- pattern guards (PatternGuards)
- implicit parameters (ImplicitParameters)
- generalised algebraic data types (GADTs)
- template haskell (TemplateHaskell)
- empty data type declarations (EmptyDataDecls)
- unboxed tuples (UnboxedTuples)
- regular patterns (RegularPatterns)
- HSP-style XML expressions and patterns (XmlSyntax)
All nodes in the syntax tree are annotated with something of a user-definable data type. When parsing, this annotation will contain information about the source location that the particular node comes from.

The instance declaration rule, which is, roughly, the part of the instance declaration before the where
keyword.
Example: instance Ord a => Ord (Maybe a)
is represented as
IRule () Nothing (Just (CxSingle () (ClassA () (UnQual () (Ident () "Ord")) [ TyVar () (Ident () "a") ]))) (IHApp () (IHCon () (UnQual () (Ident () "Ord"))) (TyParen () (TyApp () (TyCon () (UnQual () (Ident () "Maybe"))) (TyVar () (Ident () "a")))))
An optional explicit forall after instance
is supported:
instance forall a . Ord a => Ord (Maybe a) where
becomes
IRule () (Just [ UnkindedVar () (Ident () "a") ]) ...

The instance head. The split between rule/head allow us to represent
instance (Bounded a => Bounded [a]) where
faithfully.
The structure of InstHead
follows one of DeclHead
.
For example, instance C (Maybe a) Int where
is represented as
IHApp () (IHApp () (IHCon () (UnQual () (Ident () "C"))) (TyParen () (TyApp () (TyCon () (UnQual () (Ident () "Maybe"))) (TyVar () (Ident () "a"))))) (TyCon () (UnQual () (Ident () "Int")))))

If the GADT is declared using the record syntax, e.g.
data Ty where TCon :: { field1 :: Int, field2 :: Bool } -> Ty
then the fields are stored as a list of FieldDecl
s, and the final type
(Ty
in the above example) is stored in the last Type
field.
If the GADT is declared using the ordinary syntax, e.g.
data Ty where TCon :: Int -> Bool -> Ty
then
is Maybe
[FieldDecl

, and the whole constructor's
type (such as Int -> Bool -> Ty
) is stored in the last Type
