Methods

(<>) :: Q a -> Q a -> Q a Source #

sconcat :: NonEmpty (Q a) -> Q a Source #

stimes :: Integral b => b -> Q a -> Q a Source #

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

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.

Administration: errors, locations and IO

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.

reportWarning :: String -> Q () Source #

Report a warning to the user, and carry on.

report :: Bool -> String -> Q () Source #

Deprecated: Use reportError or reportWarning instead

Report an error (True) or warning (False), but carry on; use fail to stop.

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.

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.

Querying the compiler

Reify

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.

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.

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

type Unlifted = Bool Source #

In PrimTyConI, is the type constructor unlifted?

Language extension lookup

data Extension Source #

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] Source #

List all enabled language extensions.

isExtEnabled :: Extension -> Q Bool Source #

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

Name lookup

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.

Fixity lookup

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.

Type lookup

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.

Instance lookup

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).

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

Is the list of instances returned by reifyInstances nonempty?

Roles lookup

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.

Annotation lookup

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

Constructor strictness lookup

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.

Typed expressions

data 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" ||])

Lift a monadic action producing code into the typed Code representation

Names

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.

Constructing names

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") |]

Deconstructing names

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

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 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.

type Cxt Source #

Arguments

 = [Pred]
(Eq a, Ord b)

type Pred = Type Source #

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 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.

Documentation

putDoc :: DocLoc -> String -> Q () Source #

Add Haddock documentation to the specified location. This will overwrite any documentation at the location if it already exists. This will reify the specified name, so it must be in scope when you call it. If you want to add documentation to something that you are currently splicing, you can use addModFinalizer e.g.

do
  let nm = mkName "x"
  addModFinalizer $ putDoc (DeclDoc nm) "Hello"
  [d| $(varP nm) = 42 |]

The helper functions withDecDoc and withDecsDoc will do this for you, as will the funD_doc and other _doc combinators. You most likely want to have the -haddock flag turned on when using this. Adding documentation to anything outside of the current module will cause an error.

getDoc :: DocLoc -> Q (Maybe String) Source #

Retreives the Haddock documentation at the specified location, if one exists. It can be used to read documentation on things defined outside of the current module, provided that those modules were compiled with the -haddock flag.

data DocLoc Source #

A location at which to attach Haddock documentation. Note that adding documentation to a Name defined oustide of the current module will cause an error.

Constructors

ModuleDoc

At the current module's header.

DeclDoc Name

At a declaration, not necessarily top level.

ArgDoc Name Int

At a specific argument of a function, indexed by its position.

InstDoc Type

At a class or family instance.
