class Lift (t :: TYPE r) where #
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

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
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.
Multiplicity annotations for data types are currently not supported in Template Haskell (i.e. all fields represented by Template Haskell will be linear).

Recover from errors raised by reportError or fail.
reportError :: String -> Q () #
Report an error to the user, but allow the current splice's computation to carry on. To abort the computation, use fail.
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.

class Monad m => Quote (m :: Type -> Type) where #
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
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.
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") |]
Typed wrapper around an Exp.
This is the typed representation of terms produced by typed quotes.

type VarBangType = (Name, Bang, Type) #
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.

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.
Varieties of allowed instance overlap.

newtype Code (m :: Type -> Type) (a :: TYPE r) #
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 typea, then the quotation has typeQuote m => Code m a - typed splices inside of typed quotes, written as
$$(...)where...is an arbitrary expression of typeQuote m => Code m a
Traditional expression quotes and splices let us construct ill-typed expressions:
>>>fmap ppr $ runQ (unTypeCode [| True == $( [| "foo" |] ) |])GHC.Types.True GHC.Classes.== "foo">>>GHC.Types.True GHC.Classes.== "foo"<interactive> error: • Couldn't match expected type ‘Bool’ with actual type ‘[Char]’ • In the second argument of ‘(==)’, namely ‘"foo"’ In the expression: True == "foo" In an equation for ‘it’: it = True == "foo"
With typed expressions, the type error occurs when constructing the Template Haskell expression:
>>>fmap ppr $ runQ (unTypeCode [|| True == $$( [|| "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" ||])

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
pattern P :: forall universals. required constraints
=> forall existentials. provided constraints
=> t1 -> t2 -> ... -> tn -> tconsisting of four parts:
- the (possibly empty lists of) universally quantified type variables and required constraints on them.
- the (possibly empty lists of) existentially quantified type variables and the provided constraints on them.
- the types
t1,t2, ..,tnofx1,x2, ..,xn, respectively - the type
tof<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
pprPatSynTypeabbreviates 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
PatSynSigDeither 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 InstanceDec = Dec #
InstanceDec describes 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]DataInstDorNewtypeInstD(with empty derived[)Name]TySynInstD
In PrimTyConI, arity of the type constructor
In UnboxedSumE, UnboxedSumT, and UnboxedSumP, the total number of
SumAlts. For example, (#|#) has a SumArity of 2.
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 #

unTypeQ :: forall a m. Quote m => m (TExp a) -> m Exp #
Discard the type annotation and produce a plain Template Haskell expression
Representation-polymorphic since template-haskell-2.16.0.0.
unsafeTExpCoerce :: forall a m. Quote m => m Exp -> m (TExp a) #
Annotate the Template Haskell expression with a type
This is unsafe because GHC cannot check for you that the expression really does have the type you claim it has.
Representation-polymorphic since template-haskell-2.16.0.0.
liftCode :: forall a m. m (TExp a) -> Code m a #
Lift a monadic action producing code into the typed Code
representation
hoistCode :: Monad m => (forall x. m x -> n x) -> Code m a -> Code n a #
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 #
Variant of (>>=) which allows effectful computations to be injected into code generation.
bindCode_ :: Monad m => m a -> Code m b -> Code m b #
Variant of (>>) which allows effectful computations to be injected into code generation.
joinCode :: Monad m => m (Code m a) -> Code m a #
A useful combinator for embedding monadic actions into Code
myCode :: ... => Code m a
myCode = joinCode $ do
x <- someSideEffect
return (makeCodeWith x)
report :: Bool -> String -> Q () #
Deprecated: Use reportError or reportWarning instead
Report an error (True) or warning (False),
but carry on; use fail to stop.
reportWarning :: String -> Q () #
Report a warning to the user, and carry on.
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.
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.
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 . If the function
Just (Fixity 7 InfixR)bar does not have a fixity declaration, then reifyFixity 'bar returns
Nothing, so you may assume bar has defaultFixity.
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.
newDeclarationGroup :: Q [Dec] #
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
)
reifyInstances :: Name -> [Type] -> Q [InstanceDec] #
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 [contains theTupleT2 `AppT`ConT''A `AppT`ConT''B ]instance (Eq a, Eq b) => Eq (a, b)regardless of whetherAandBthemselves implementEqreifyInstances ''Show [produces every available instance ofVarT(mkName"a") ]Eq
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.
reifyRoles :: Name -> Q [Role] #
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 [. The NominalR, PhantomR]NominalR is
the role of the invisible k parameter. Kind parameters are always nominal.
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.
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.
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 [ under most
circumstances, but it would return DecidedLazy, DecidedLazy][ if the
DecidedStrict, DecidedStrict]-XStrictData language extension was enabled.
isInstance :: Name -> [Type] -> Q Bool #
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.
getPackageRoot :: Q FilePath #
Get the package root for the current package which is being compiled. This can be set explicitly with the -package-root flag but is normally just the current working directory.
The motivation for this flag is to provide a principled means to remove the assumption from splices that they will be executed in the directory where the cabal file resides. Projects such as haskell-language-server can't and don't change directory when compiling files but instead set the -package-root flag appropiately.
makeRelativeToProject :: FilePath -> Q FilePath #
The input is a filepath, which if relative is offset by the package root.
addDependentFile :: FilePath -> Q () #
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 #
Obtain a temporary file path with the given suffix. The compiler will delete this file after compilation.
addTopDecls :: [Dec] -> Q () #
Add additional top-level declarations. The added declarations will be type checked along with the current declaration group.
addForeignFile :: ForeignSrcLang -> String -> Q () #
Deprecated: Use addForeignSource instead
addForeignSource :: ForeignSrcLang -> String -> Q () #
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 (831 + 1) ++ " " ++ show "libraries/template-haskell/Language/Haskell/TH/Syntax.hs"
, ...
]addForeignFilePath :: ForeignSrcLang -> FilePath -> Q () #
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 () #
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 () #
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) #
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 () #
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 #
Determine whether the given language extension is enabled in the Q monad.
extsEnabled :: Q [Extension] #
List all enabled language extensions.
putDoc :: DocLoc -> String -> Q () #
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) #
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.
addrToByteArray :: Int -> Addr# -> ByteArray #
nothingName :: Name #
nonemptyName :: Name #
dataToQa :: (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 #
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 #
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.
dataToPatQ :: (Quote m, Data a) => (forall b. Data b => b -> Maybe (m Pat)) -> a -> m Pat #
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.
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.EitherJust "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.EitherJust "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.idJust VarName>>>nameSpace (mkName "id")Nothing -- only works for top-level variable names>>>nameSpace 'Data.Maybe.JustJust DataName>>>nameSpace ''Data.Maybe.MaybeJust TcClsName>>>nameSpace ''Data.Ord.OrdJust TcClsName

Notes
Unresolved Infix
When implementing antiquotation for quasiquoters, one often wants to parse strings into expressions:
parse :: String -> Maybe Exp
But how should we parse a + b * c? If we don't know the fixities of
+ and *, we don't know whether to parse it as a + (b * c) or (a
+ b) * c.
In cases like this, use UInfixE, UInfixP, UInfixT, or PromotedUInfixT,
which stand for "unresolved infix expressionpatterntype/promoted
constructor", respectively. When the compiler is given a splice containing a
tree of UInfixE applications such as
UInfixE (UInfixE e1 op1 e2) op2 (UInfixE e3 op3 e4)
it will look up and the fixities of the relevant operators and reassociate the tree as necessary.
- trees will not be reassociated across
ParensE,ParensP, orParensT, which are of use for parsing expressions like
(a + b * c) + d * e
InfixE,InfixP,InfixT, andPromotedInfixTexpressions are never reassociated.- The
UInfixEconstructor doesn't support sections. Sections such as(a *)have no ambiguity, soInfixEsuffices. For longer sections such as(a + b * c -), use anInfixEconstructor for the outer-most section, and useUInfixEconstructors for all other operators:
InfixE Just (UInfixE ...a + b * c...) op Nothing
Sections such as (a + b +) and ((a + b) +) should be rendered
into Exps differently:
(+ a + b) ---> InfixE Nothing + (Just $ UInfixE a + b)
-- will result in a fixity error if (+) is left-infix
(+ (a + b)) ---> InfixE Nothing + (Just $ ParensE $ UInfixE a + b)
-- no fixity errors- Quoted expressions such as
[| a * b + c |] :: Q Exp [p| a : b : c |] :: Q Pat [t| T + T |] :: Q Type
will never contain UInfixE, UInfixP, UInfixT, PromotedUInfixT,
InfixT, 'PromotedInfixT, ParensE, ParensP, or ParensT constructors.
