runIO :: IO a -> Q a

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.

Querying the compiler

Reify

reify :: Name -> Q Info

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.

reifyModule :: Module -> Q ModuleInfo

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

data Info

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

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

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

• InstanceD (with empty [Dec])
• DataInstD or NewtypeInstD (with empty derived [Name])
• TySynInstD

type ParentName = Name

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

type SumAlt = Int

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:

• (#_|#) has SumAlt 1 (out of a total SumArity of 2)
• (#|_#) has SumAlt 2 (out of a total SumArity of 2)

type SumArity = Int

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

type Arity = Int

In PrimTyConI, arity of the type constructor

type Unlifted = Bool

In PrimTyConI, is the type constructor unlifted?

Language extension lookup

data Extension

The language extensions known to GHC.

Note that there is an orphan Binary instance for this type supplied by the GHC.LanguageExtensions module provided by ghc-boot. We can't provide here as this would require adding transitive dependencies to the template-haskell package, which must have a minimal dependency set.

extsEnabled :: Q [Extension]

List all enabled language extensions.

isExtEnabled :: Extension -> Q Bool

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

Name lookup

lookupTypeName :: String -> Q (Maybe Name)

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)

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

Fixity lookup

reifyFixity :: Name -> Q (Maybe Fixity)

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.

Instance lookup

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

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.

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

Is the list of instances returned by reifyInstances nonempty?

Roles lookup

reifyRoles :: Name -> Q [Role]

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.

Annotation lookup

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

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

Constructor strictness lookup

reifyConStrictness :: Name -> Q [DecidedStrictness]

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.

Typed expressions

unType :: TExp a -> Exp

Names

data Name

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.

Constructing names

mkName :: String -> Name

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") |]

newName :: String -> Q Name

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.

Deconstructing names

nameBase :: Name -> String

The name without its module prefix.

Examples

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

nameModule :: Name -> Maybe String

Module prefix of a name, if it exists.

Examples

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

namePackage :: Name -> Maybe String

A name's package, if it exists.

Examples

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

nameSpace :: Name -> Maybe NameSpace

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

>>> 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

data Con

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.

type Kind = Type

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.

type Cxt

Arguments

 = [Pred]

(Eq a, Ord b)

type Pred = Type

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

type PatSynType = Type

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

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:

(a) Reification always returns a pattern synonym's *fully* specified type in abstract syntax.

(b) 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.

(c) 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/syntax-extns.html#pattern-synonyms.
