Description

Abstract syntax definitions for Template Haskell.

Synopsis

Documentation

sequenceQ :: forall m. Monad m => forall a. [m a] -> m [a] Source #

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") |]

mkNameL :: String -> Uniq -> Name Source #

Only used internally

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
  deriving Lift

Levity-polymorphic since template-haskell-2.16.0.0.

class Monad m => Quote m 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.

data Con Source #

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 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.

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.

data TySynEqn Source #

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 [PlainTV k, KindedTV a (VarT k)])
           (AppT (AppKindT (ConT ''Foo) (VarT k)) (VarT a))
           (VarT a)

type Kind = Type Source #

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.

Varieties of allowed instance overlap.

Constructors

Overlappable

Overlaps

Both Overlapping and Overlappable

Incoherent

Both Overlappable and Overlappable, and pick an arbitrary one if multiple choices are available.

type PatSynType = Type Source #

A pattern synonym's type. Note that a pattern synonym's fully specified type has a peculiar shape coming with two forall quantifiers and two constraint contexts. For example, consider the pattern synonym

pattern P x1 x2 ... xn = <some-pattern>

P's complete type is of the following form

pattern P :: forall universals.   required constraints
          => forall existentials. provided constraints
          => t1 -> t2 -> ... -> tn -> t

consisting of four parts:

  1. the (possibly empty lists of) universally quantified type variables and required constraints on them.
  2. the (possibly empty lists of) existentially quantified type variables and the provided constraints on them.
  3. the types t1, t2, .., tn of x1, x2, .., xn, respectively
  4. the type t of <some-pattern>, mentioning only universals.

Pattern synonym types interact with TH when (a) reifying a pattern synonym, (b) pretty printing, or (c) specifying a pattern synonym's type signature explicitly:

  • Reification always returns a pattern synonym's fully specified type in abstract syntax.
  • Pretty printing via pprPatSynType abbreviates a pattern synonym's type unambiguously in concrete syntax: The rule of thumb is to print initial empty universals and the required context as () =>, if existentials and a provided context follow. If only universals and their required context, but no existentials are specified, only the universals and their required context are printed. If both or none are specified, so both (or none) are printed.
  • When specifying a pattern synonym's type explicitly with PatSynSigD either one of the universals, the existentials, or their contexts may be left empty.

See the GHC user's guide for more information on pattern synonyms and their types: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#pattern-synonyms.

type Unlifted = Bool Source #

In PrimTyConI, is the type constructor unlifted?

type Arity = Int Source #

In PrimTyConI, arity of the type constructor

type SumArity = Int Source #

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

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 ParentName = Name Source #

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

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.

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 type a, then the quotation has type Q (TExp a)
  • typed splices inside of typed quotes, written as $$(...) where ... is an arbitrary expression of type Q (TExp a)

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" ||])

-> Q a

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.

reify :: Name -> Q Info Source #

reify looks up information about the Name.

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.

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 visible instances 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 Eq

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

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

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

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.

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.

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.

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

Is the list of instances returned by reifyInstances nonempty?

location :: Q Loc Source #

The location at which this computation is spliced.

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.

addDependentFile :: FilePath -> Q () Source #

Record external files that runIO is using (dependent upon). The compiler can then recognize that it should re-compile the Haskell file when an external file changes.

Expects an absolute file path.

Notes:

  • ghc -M does not know about these dependencies - it does not execute TH.
  • The dependency is based on file content, not a modification time

addTempFile :: String -> Q FilePath Source #

Obtain a temporary file path with the given suffix. The compiler will delete this file after compilation.

addTopDecls :: [Dec] -> Q () Source #

Add additional top-level declarations. The added declarations will be type checked along with the current declaration group.

addForeignFile :: ForeignSrcLang -> String -> Q () Source #

Deprecated: Use addForeignSource instead

addForeignSource :: ForeignSrcLang -> String -> Q () Source #

Emit a foreign file which will be compiled and linked to the object for the current module. Currently only languages that can be compiled with the C compiler are supported, and the flags passed as part of -optc will be also applied to the C compiler invocation that will compile them.

Note that for non-C languages (for example C++) extern C directives must be used to get symbols that we can access from Haskell.

To get better errors, it is recommended to use #line pragmas when emitting C files, e.g.

{-# LANGUAGE CPP #-}
...
addForeignSource LangC $ unlines
  [ "#line " ++ show (682 + 1) ++ " " ++ show "libraries/template-haskell/./Language/Haskell/TH/Syntax.hs"
  , ...
  ]

addForeignFilePath :: ForeignSrcLang -> FilePath -> Q () Source #

Same as addForeignSource, but expects to receive a path pointing to the foreign file instead of a String of its contents. Consider using this in conjunction with addTempFile.

This is a good alternative to addForeignSource when you are trying to directly link in an object file.

addModFinalizer :: Q () -> Q () Source #

Add a finalizer that will run in the Q monad after the current module has been type checked. This only makes sense when run within a top-level splice.

The finalizer is given the local type environment at the splice point. Thus reify is able to find the local definitions when executed inside the finalizer.

addCorePlugin :: String -> Q () Source #

Adds a core plugin to the compilation pipeline.

addCorePlugin m has almost the same effect as passing -fplugin=m to ghc in the command line. The major difference is that the plugin module m must not belong to the current package. When TH executes, it is too late to tell the compiler that we needed to compile first a plugin module in the current package.

getQ :: Typeable a => Q (Maybe a) Source #

Get state from the Q monad. Note that the state is local to the Haskell module in which the Template Haskell expression is executed.

putQ :: Typeable a => a -> Q () Source #

Replace the state in the Q monad. Note that the state is local to the Haskell module in which the Template Haskell expression is executed.

isExtEnabled :: Extension -> Q Bool Source #

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

extsEnabled :: Q [Extension] Source #

List all enabled language extensions.

dataToQa :: forall m a k q. (Quote m, Data a) => (Name -> k) -> (Lit -> m q) -> (k -> [m q] -> m q) -> (forall b. Data b => b -> Maybe (m q)) -> a -> m q Source #

dataToQa is an internal utility function for constructing generic conversion functions from types with Data instances to various quasi-quoting representations. See the source of dataToExpQ and dataToPatQ for two example usages: mkCon, mkLit and appQ are overloadable to account for different syntax for expressions and patterns; antiQ allows you to override type-specific cases, a common usage is just const Nothing, which results in no overloading.

dataToExpQ :: (Quote m, Data a) => (forall b. Data b => b -> Maybe (m Exp)) -> a -> m Exp Source #

dataToExpQ converts a value to a Exp representation of the same value, in the SYB style. It is generalized to take a function override type-specific cases; see liftData for a more commonly used variant.

liftData :: (Quote m, Data a) => a -> m Exp Source #

liftData is a variant of lift in the Lift type class which works for any type with a Data instance.

dataToPatQ :: (Quote m, Data a) => (forall b. Data b => b -> Maybe (m Pat)) -> a -> m Pat Source #

dataToPatQ converts a value to a Pat representation of the same value, in the SYB style. It takes a function to handle type-specific cases, alternatively, pass const Nothing to get default behavior.

nameBase :: Name -> String Source #

The name without its module prefix.

Examples

Expand
>>> nameBase ''Data.Either.Either
"Either"
>>> nameBase (mkName "foo")
"foo"
>>> nameBase (mkName "Module.foo")
"foo"

nameModule :: Name -> Maybe String Source #

Module prefix of a name, if it exists.

Examples

Expand
>>> nameModule ''Data.Either.Either
Just "Data.Either"
>>> nameModule (mkName "foo")
Nothing
>>> nameModule (mkName "Module.foo")
Just "Module"

namePackage :: Name -> Maybe String Source #

A name's package, if it exists.

Examples

Expand
>>> namePackage ''Data.Either.Either
Just "base"
>>> namePackage (mkName "foo")
Nothing
>>> namePackage (mkName "Module.foo")
Nothing

nameSpace :: Name -> Maybe NameSpace Source #

Returns whether a name represents an occurrence of a top-level variable (VarName), data constructor (DataName), type constructor, or type class (TcClsName). If we can't be sure, it returns Nothing.

Examples

Expand
>>> nameSpace 'Prelude.id
Just VarName
>>> nameSpace (mkName "id")
Nothing -- only works for top-level variable names
>>> nameSpace 'Data.Maybe.Just
Just DataName
>>> nameSpace ''Data.Maybe.Maybe
Just TcClsName
>>> nameSpace ''Data.Ord.Ord
Just TcClsName

mkNameU :: String -> Uniq -> Name Source #
