In PrimTyConI, is the type constructor unlifted?
data DecidedStrictness Source #
Unlike SourceStrictness and SourceUnpackedness, DecidedStrictness
refers to the strictness annotations that the compiler chooses for a data constructor
field, which may be different from what is written in source code.
Note that non-unpacked strict fields are assigned DecidedLazy when a bang would be inappropriate,
such as the field of a newtype constructor and fields that have an unlifted type.
See reifyConStrictness for more information.

A single data constructor.
The constructors for Con can roughly be divided up into two categories:
those for constructors with "vanilla" syntax (NormalC, RecC, and
InfixC), and those for constructors with GADT syntax (GadtC and
RecGadtC). The ForallC constructor, which quantifies additional type
variables and class contexts, can surround either variety of constructor.
However, the type variables that it quantifies are different depending
on what constructor syntax is used:
- If a
ForallCsurrounds a constructor with vanilla syntax, then theForallCwill only quantify existential type variables. For example:
data Foo a = forall b. MkFoo a b
In MkFoo, ForallC will quantify b, but not a.
- If a
ForallCsurrounds a constructor with GADT syntax, then theForallCwill quantify all type variables used in the constructor. For example:
data Bar a b where
MkBar :: (a ~ b) => c -> MkBar a b
In MkBar, ForallC will quantify a, b, and c.
Multiplicity annotations for data types are currently not supported in Template Haskell (i.e. all fields represented by Template Haskell will be linear).

class Monad m => Quote m where Source #
The Quote class implements the minimal interface which is necessary for
desugaring quotations.
- The
Monad msuperclass is needed to stitch together the different AST fragments. newNameis used when desugaring binding structures such as lambdas to generate fresh names.
Therefore the type of an untyped quotation in GHC is `Quote m => m Exp`
For many years the type of a quotation was fixed to be `Q Exp` but by
more precisely specifying the minimal interface it enables the Exp to
be extracted purely from the quotation without interacting with Q.
Methods
newName :: String -> m Name Source #
Generate a fresh name, which cannot be captured.
For example, this:
f = $(do
nm1 <- newName "x"
let nm2 = mkName "x"
return (LamE [VarP nm1] (LamE [VarP nm2] (VarE nm1)))
)will produce the splice
f = \x0 -> \x -> x0
In particular, the occurrence VarE nm1 refers to the binding VarP nm1,
and is not captured by the binding VarP nm2.
Although names generated by newName cannot be captured, they can
capture other names. For example, this:
g = $(do nm1 <- newName "x" let nm2 = mkName "x" return (LamE [VarP nm2] (LamE [VarP nm1] (VarE nm2))) )
will produce the splice
g = \x -> \x0 -> x0
since the occurrence VarE nm2 is captured by the innermost binding
of x, namely VarP nm1.

newtype TExp (a :: TYPE (r :: RuntimeRep)) Source #
Represents an expression which has type a. Built on top of Exp, typed
expressions allow for type-safe splicing via:
- typed quotes, written as
[|| ... ||]where...is an expression; if that expression has typea, then the quotation has typeQ(TExpa) - typed splices inside of typed quotes, written as
$$(...)where...is an arbitrary expression of typeQ(TExpa)
Traditional expression quotes and splices let us construct ill-typed expressions:
>>>fmap ppr $ runQ [| True == $( [| "foo" |] ) |]GHC.Types.True GHC.Classes.== "foo">>>GHC.Types.True GHC.Classes.== "foo"<interactive> error: • Couldn't match expected type ‘Bool’ with actual type ‘[Char]’ • In the second argument of ‘(==)’, namely ‘"foo"’ In the expression: True == "foo" In an equation for ‘it’: it = True == "foo"
With typed expressions, the type error occurs when constructing the Template Haskell expression:
>>>fmap ppr $ runQ [|| True == $$( [|| "foo" ||] ) ||]<interactive> error: • Couldn't match type ‘[Char]’ with ‘Bool’ Expected type: Q (TExp Bool) Actual type: Q (TExp [Char]) • In the Template Haskell quotation [|| "foo" ||] In the expression: [|| "foo" ||] In the Template Haskell splice $$([|| "foo" ||])
Representation-polymorphic since template-haskell-2.16.0.0.

Fields

An abstract type representing names in the syntax tree.
Names can be constructed in several ways, which come with different
name-capture guarantees (see Language.Haskell.TH.Syntax for
an explanation of name capture):
- the built-in syntax
'fand''Tcan be used to construct names, The expression'fgives aNamewhich refers to the valuefcurrently in scope, and''Tgives aNamewhich refers to the typeTcurrently in scope. These names can never be captured. lookupValueNameandlookupTypeNameare similar to'fand''Trespectively, but theNames are looked up at the point where the current splice is being run. These names can never be captured.newNamemonadically generates a new name, which can never be captured.mkNamegenerates a capturable name.
Names constructed using newName and mkName may be used in bindings
(such as let x = ... or x -> ...), but names constructed using
lookupValueName, lookupTypeName, 'f, ''T may not.

One equation of a type family instance or closed type family. The arguments are the left-hand-side type and the right-hand-side result.
For instance, if you had the following type family:
type family Foo (a :: k) :: k where forall k (a :: k). Foo @k a = a
The Foo @k a = a equation would be represented as follows:
TySynEqn(Just[PlainTVk,KindedTVa (VarTk)]) (AppT(AppKindT(ConT''Foo) (VarTk)) (VarTa)) (VarTa)
Instances
data TypeFamilyHead Source #
Common elements of OpenTypeFamilyD and ClosedTypeFamilyD. By
analogy with "head" for type classes and type class instances as
defined in Type classes: an exploration of the design space, the
TypeFamilyHead is defined to be the elements of the declaration
between type family and where.
