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.

Constructors

type Unlifted = Bool Source #

In PrimTyConI, is the type constructor unlifted?

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 -> Code Q 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 ≡ unTypeCode (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
  deriving Lift

data Con Source #

A 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 ForallC surrounds a constructor with vanilla syntax, then the ForallC will 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 ForallC surrounds a constructor with GADT syntax, then the ForallC will 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).

recover Source #

Arguments

:: Q a

handler to invoke on failure

-> Q a

computation to run

-> Q a 

Recover from errors raised by reportError or fail.

reportError :: String -> Q () Source #

Report an error to the user, but allow the current splice's computation to carry on. To abort the computation, use fail.

runIO :: IO a -> Q a Source #

The runIO function lets you run an I/O computation in the Q monad. Take care: you are guaranteed the ordering of calls to runIO within a single Q computation, but not about the order in which splices are run.

Note: for various murky reasons, stdout and stderr handles are not necessarily flushed when the compiler finishes running, so you should flush them yourself.

runQ :: Quasi m => Q a -> m a Source #

class Monad m => Quote (m :: Type -> Type) where Source #

The Quote class implements the minimal interface which is necessary for desugaring quotations.

  • The Monad m superclass is needed to stitch together the different AST fragments.
  • newName is 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.

reify :: Name -> Q Info Source #

reify looks up information about the Name. It will fail with a compile error if the Name is not visible. A Name is visible if it is imported or defined in a prior top-level declaration group. See the documentation for newDeclarationGroup for more details.

It is sometimes useful to construct the argument name using lookupTypeName or lookupValueName to ensure that we are reifying from the right namespace. For instance, in this context:

data D = D

which D does reify (mkName "D") return information about? (Answer: D-the-type, but don't rely on it.) To ensure we get information about D-the-value, use lookupValueName:

do
  Just nm <- lookupValueName "D"
  reify nm

and to get information about D-the-type, use lookupTypeName.

reifyModule :: Module -> Q ModuleInfo Source #

reifyModule mod looks up information about module mod. To look up the current module, call this function with the return value of thisModule.

newDeclarationGroup :: Q [Dec] Source #

Template Haskell is capable of reifying information about types and terms defined in previous declaration groups. Top-level declaration splices break up declaration groups.

For an example, consider this code block. We define a datatype X and then try to call reify on the datatype.

module Check where

data X = X
    deriving Eq

$(do
    info <- reify ''X
    runIO $ print info
 )

This code fails to compile, noting that X is not available for reification at the site of reify. We can fix this by creating a new declaration group using an empty top-level splice:

data X = X
    deriving Eq

$(pure [])

$(do
    info <- reify ''X
    runIO $ print info
 )

We provide newDeclarationGroup as a means of documenting this behavior and providing a name for the pattern.

Since top level splices infer the presence of the $( ... ) brackets, we can also write:

data X = X
    deriving Eq

newDeclarationGroup

$(do
    info <- reify ''X
    runIO $ print info
 )

data Info Source #

Obtained from reify in the Q Monad.

Constructors

ClassI Dec [InstanceDec]

A class, with a list of its visible instances

ClassOpI Name Type ParentName

A class method

TyConI Dec

A "plain" type constructor. "Fancier" type constructors are returned using PrimTyConI or FamilyI as appropriate. At present, this reified declaration will never have derived instances attached to it (if you wish to check for an instance, see reifyInstances).

FamilyI Dec [InstanceDec]

A type or data family, with a list of its visible instances. A closed type family is returned with 0 instances.

PrimTyConI Name Arity Unlifted

A "primitive" type constructor, which can't be expressed with a Dec. Examples: (->), Int#.

DataConI Name Type ParentName

A data constructor

PatSynI Name PatSynType

A pattern synonym

VarI Name Type (Maybe Dec)

A "value" variable (as opposed to a type variable, see TyVarI).

The Maybe Dec field contains Just the declaration which defined the variable - including the RHS of the declaration - or else Nothing, in the case where the RHS is unavailable to the compiler. At present, this value is always Nothing: returning the RHS has not yet been implemented because of lack of interest.

TyVarI Name Type

A type variable.

The Type field contains the type which underlies the variable. At present, this is always VarT theName, but future changes may permit refinement of this.

type InstanceDec = Dec Source #

InstanceDec describes a single instance of a class or type function. It is just a Dec, but guaranteed to be one of the following:

type ParentName = Name Source #

In ClassOpI and DataConI, name of the parent class or type

type SumAlt = Int Source #

In UnboxedSumE and UnboxedSumP, the number associated with a particular data constructor. SumAlts are one-indexed and should never exceed the value of its corresponding SumArity. For example:

type SumArity = Int Source #

In UnboxedSumE, UnboxedSumT, and UnboxedSumP, the total number of SumAlts. For example, (#|#) has a SumArity of 2.

type Arity = Int Source #

In PrimTyConI, arity of the type constructor

extsEnabled :: Q [Extension] Source #

List all enabled language extensions.

isExtEnabled :: Extension -> Q Bool Source #

Determine whether the given language extension is enabled in the Q monad.

lookupTypeName :: String -> Q (Maybe Name) Source #

Look up the given name in the (type namespace of the) current splice's scope. See Language.Haskell.TH.Syntax for more details.

lookupValueName :: String -> Q (Maybe Name) Source #

Look up the given name in the (value namespace of the) current splice's scope. See Language.Haskell.TH.Syntax for more details.

reifyFixity :: Name -> Q (Maybe Fixity) Source #

reifyFixity nm attempts to find a fixity declaration for nm. For example, if the function foo has the fixity declaration infixr 7 foo, then reifyFixity 'foo would return Just (Fixity 7 InfixR). If the function bar does not have a fixity declaration, then reifyFixity 'bar returns Nothing, so you may assume bar has defaultFixity.

reifyType :: Name -> Q Type Source #

reifyType nm attempts to find the type or kind of nm. For example, reifyType 'not returns Bool -> Bool, and reifyType ''Bool returns Type. This works even if there's no explicit signature and the type or kind is inferred.

reifyInstances :: Name -> [Type] -> Q [InstanceDec] Source #

reifyInstances nm tys returns a list of all visible instances (see below for "visible") of nm tys. That is, if nm is the name of a type class, then all instances of this class at the types tys are returned. Alternatively, if nm is the name of a data family or type family, all instances of this family at the types tys are returned.

Note that this is a "shallow" test; the declarations returned merely have instance heads which unify with nm tys, they need not actually be satisfiable.

  • reifyInstances ''Eq [ TupleT 2 `AppT` ConT ''A `AppT` ConT ''B ] contains the instance (Eq a, Eq b) => Eq (a, b) regardless of whether A and B themselves implement Eq
  • reifyInstances ''Show [ VarT (mkName "a") ] produces every available instance of Show

There is one edge case: reifyInstances ''Typeable tys currently always produces an empty list (no matter what tys are given).

In principle, the *visible* instances are * all instances defined in a prior top-level declaration group (see docs on newDeclarationGroup), or * all instances defined in any module transitively imported by the module being compiled

However, actually searching all modules transitively below the one being compiled is unreasonably expensive, so reifyInstances will report only the instance for modules that GHC has had some cause to visit during this compilation. This is a shortcoming: reifyInstances might fail to report instances for a type that is otherwise unusued, or instances defined in a different component. You can work around this shortcoming by explicitly importing the modules whose instances you want to be visible. GHC issue #20529 has some discussion around this.

isInstance :: Name -> [Type] -> Q Bool Source #

Is the list of instances returned by reifyInstances nonempty?

If you're confused by an instance not being visible despite being defined in the same module and above the splice in question, see the docs for newDeclarationGroup for a possible explanation.

reifyRoles :: Name -> Q [Role] Source #

reifyRoles nm returns the list of roles associated with the parameters (both visible and invisible) of the tycon nm. Fails if nm cannot be found or is not a tycon. The returned list should never contain InferR.

An invisible parameter to a tycon is often a kind parameter. For example, if we have

type Proxy :: forall k. k -> Type
data Proxy a = MkProxy

and reifyRoles Proxy, we will get [NominalR, PhantomR]. The NominalR is the role of the invisible k parameter. Kind parameters are always nominal.

reifyAnnotations :: Data a => AnnLookup -> Q [a] Source #

reifyAnnotations target returns the list of annotations associated with target. Only the annotations that are appropriately typed is returned. So if you have Int and String annotations for the same target, you have to call this function twice.

data AnnLookup Source #

Annotation target for reifyAnnotations

reifyConStrictness :: Name -> Q [DecidedStrictness] Source #

reifyConStrictness nm looks up the strictness information for the fields of the constructor with the name nm. Note that the strictness information that reifyConStrictness returns may not correspond to what is written in the source code. For example, in the following data declaration:

data Pair a = Pair a a

reifyConStrictness would return [DecidedLazy, DecidedLazy] under most circumstances, but it would return [DecidedStrict, DecidedStrict] if the -XStrictData language extension was enabled.

newtype TExp (a :: TYPE r) Source #

Typed wrapper around an Exp.

This is the typed representation of terms produced by typed quotes.

Representation-polymorphic since template-haskell-2.16.0.0.

Constructors

TExp 

Fields

  • unType :: Exp

    Underlying untyped Template Haskell expression

newtype Code (m :: Type -> Type) (a :: TYPE r) Source #

Represents an expression which has type a, built in monadic context m. Built on top of TExp, typed expressions allow for type-safe splicing via:

  • typed quotes, written as [|| ... ||] where ... is an expression; if that expression has type a, then the quotation has type Quote m => Code m a
  • typed splices inside of typed quotes, written as $$(...) where ... is an arbitrary expression of type Quote m => Code m a

Traditional expression quotes and splices let us construct ill-typed expressions:

>>> fmap ppr $ runQ (unTypeCode [| 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 (unTypeCode [|| True == $$( [|| "foo" ||] ) ||])
<interactive> error:
    • Couldn't match type ‘[Char]’ with ‘Bool’
      Expected type: Code Q Bool
        Actual type: Code Q [Char]
    • In the Template Haskell quotation [|| "foo" ||]
      In the expression: [|| "foo" ||]
      In the Template Haskell splice $$([|| "foo" ||])

Constructors

Code 

Fields

unTypeCode :: forall a m. Quote m => Code m a -> m Exp Source #

Extract the untyped representation from the typed representation

unsafeCodeCoerce :: forall a m. Quote m => m Exp -> Code m a Source #

Unsafely convert an untyped code representation into a typed code representation.

hoistCode :: Monad m => (forall x. m x -> n x) -> Code m a -> Code n a Source #

Modify the ambient monad used during code generation. For example, you can use hoistCode to handle a state effect: handleState :: Code (StateT Int Q) a -> Code Q a handleState = hoistCode (flip runState 0)

bindCode :: Monad m => m a -> (a -> Code m b) -> Code m b Source #

Variant of (>>=) which allows effectful computations to be injected into code generation.

bindCode_ :: Monad m => m a -> Code m b -> Code m b Source #

Variant of (>>) which allows effectful computations to be injected into code generation.

joinCode :: Monad m => m (Code m a) -> Code m a Source #

A useful combinator for embedding monadic actions into Code myCode :: ... => Code m a myCode = joinCode $ do x <- someSideEffect return (makeCodeWith x)

liftCode :: forall a m. m (TExp a) -> Code m a Source #

Lift a monadic action producing code into the typed Code representation

data Name Source #

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 'f and ''T can be used to construct names, The expression 'f gives a Name which refers to the value f currently in scope, and ''T gives a Name which refers to the type T currently in scope. These names can never be captured.
  • lookupValueName and lookupTypeName are similar to 'f and ''T respectively, but the Names are looked up at the point where the current splice is being run. These names can never be captured.
  • newName monadically generates a new name, which can never be captured.
  • mkName generates 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.

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"

f = [| pi + $(dyn "pi") |]

>>> nameSpace 'Prelude.id
Just VarName
