TExp 

Fields

unTypeQ :: Q (TExp a) -> Q Exp Source #

newName :: String -> Q 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.

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.

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.

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.

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.

The functions lookupTypeName and lookupValueName provide a way to query the current splice's context for what names are in scope. The function lookupTypeName queries the type namespace, whereas lookupValueName queries the value namespace, but the functions are otherwise identical.

A call lookupValueName s will check if there is a value with name s in scope at the current splice's location. If there is, the Name of this value is returned; if not, then Nothing is returned.

The returned name cannot be "captured". For example:

f = "global"
g = $( do
         Just nm <- lookupValueName "f"
         [| let f = "local" in $( varE nm ) |]

In this case, g = "global"; the call to lookupValueName returned the global f, and this name was not captured by the local definition of f.

The lookup is performed in the context of the top-level splice being run. For example:

f = "global"
g = $( [| let f = "local" in
           $(do
               Just nm <- lookupValueName "f"
               varE nm
            ) |] )

Again in this example, g = "global", because the call to lookupValueName queries the context of the outer-most $(...).

Operators should be queried without any surrounding parentheses, like so:

lookupValueName "+"

Qualified names are also supported, like so:

lookupValueName "Prelude.+"
lookupValueName "Prelude.map"

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.

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.

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

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

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

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.

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

Get state from the Q monad.

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

Replace the state in the Q monad.

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.

returnQ :: a -> Q a Source #

bindQ :: Q a -> (a -> Q b) -> Q b Source #

sequenceQ :: [Q a] -> Q [a] Source #

class Lift t 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 ([| ... |]) but not at the top level. As an example:

add1 :: Int -> Q Exp
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.

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

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

dataToExpQ converts a value to a 'Q 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 :: Data a => a -> Q Exp Source #

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

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

dataToPatQ converts a value to a 'Q 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.

Much of Name API is concerned with the problem of name capture, which can be seen in the following example.

f expr = [| let x = 0 in $expr |]
...
g x = $( f [| x |] )
h y = $( f [| y |] )

A naive desugaring of this would yield:

g x = let x = 0 in x
h y = let x = 0 in y

All of a sudden, g and h have different meanings! In this case, we say that the x in the RHS of g has been captured by the binding of x in f.

What we actually want is for the x in f to be distinct from the x in g, so we get the following desugaring:

g x = let x' = 0 in x
h y = let x' = 0 in y

which avoids name capture as desired.

In the general case, we say that a Name can be captured if the thing it refers to can be changed by adding new declarations.

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.

type Rep NameSpace Source # 
type Rep NameSpace = D1 (MetaData "NameSpace" "Language.Haskell.TH.Syntax" "template-haskell" False) ((:+:) (C1 (MetaCons "VarName" PrefixI False) U1) ((:+:) (C1 (MetaCons "DataName" PrefixI False) U1) (C1 (MetaCons "TcClsName" PrefixI False) U1)))

type Uniq = Int Source #

nameBase :: Name -> String Source #

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 Source #

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 Source #

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 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

>>> 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

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") |]

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

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

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

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.

Default fixity: infixl 9

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, or UInfixT, which stand for "unresolved infix expressionpatterntype", 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, or ParensT, which are of use for parsing expressions like
(a + b * c) + d * e
  • InfixE, InfixP, and InfixT expressions are never reassociated.
  • The UInfixE constructor doesn't support sections. Sections such as (a *) have no ambiguity, so InfixE suffices. For longer sections such as (a + b * c -), use an InfixE constructor for the outer-most section, and use UInfixE constructors 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, InfixT, ParensE, ParensP, or ParensT constructors.
