mkName :: String -> Name Source #
Generate a capturable name. Occurrences of such names will be resolved according to the Haskell scoping rules at the occurrence site.
For example:
f = [| pi + $(varE (mkName "pi")) |] ... g = let pi = 3 in $f
In this case, g is desugared to
g = Prelude.pi + 3
Note that mkName may be used with qualified names:
mkName "Prelude.pi"
See also dyn for a useful combinator. The above example could
be rewritten using dyn as
f = [| pi + $(dyn "pi") |]
unTypeCode :: forall (r :: RuntimeRep) (a :: TYPE r) m. Quote m => Code m a -> m Exp Source #
Extract the untyped representation from the typed representation
unsafeCodeCoerce :: forall (r :: RuntimeRep) (a :: TYPE r) m. Quote m => m Exp -> Code m a Source #
Unsafely convert an untyped code representation into a typed code representation.
class Lift (t :: TYPE r) where Source #
A Lift instance can have any of its values turned into a Template
Haskell expression. This is needed when a value used within a Template
Haskell quotation is bound outside the Oxford brackets ([| ... |] or
[|| ... ||]) but not at the top level. As an example:
add1 :: Int -> Q (TExp Int) add1 x = [|| x + 1 ||]
Template Haskell has no way of knowing what value x will take on at
splice-time, so it requires the type of x to be an instance of Lift.
A Lift instance must satisfy $(lift x) ≡ x and $$(liftTyped x) ≡ x
for all x, where $(...) and $$(...) are Template Haskell splices.
It is additionally expected that lift x ≡ unTypeQ (liftTyped x)
Lift instances can be derived automatically by use of the -XDeriveLift
GHC language extension:
{-# LANGUAGE DeriveLift #-}
module Foo where
import Language.Haskell.TH.Syntax
data Bar a = Bar1 a (Bar a) | Bar2 String

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.

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.

Instances
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.

Since the advent of ConstraintKinds, constraints are really just types.
Equality constraints use the EqualityT constructor. Constraints may also
be tuples of other constraints.

Instances
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)

To avoid duplication between kinds and types, they
are defined to be the same. Naturally, you would never
have a type be StarT and you would never have a kind
be SigT, but many of the other constructors are shared.
Note that the kind Bool is denoted with ConT, not
PromotedT. Similarly, tuple kinds are made with TupleT,
not PromotedTupleT.
