fromKeys :: Ord k => v -> [k] -> Map k v Source #
Initialize a Map from a default value and a list of keys
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") |]

type VarBangTypeQ = Q VarBangType #
An abstract type representing names in the syntax tree.
Name
s 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 aName
which refers to the valuef
currently in scope, and''T
gives aName
which refers to the typeT
currently in scope. These names can never be captured. lookupValueName
andlookupTypeName
are similar to'f
and''T
respectively, but theName
s 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.

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

fromList :: Ord k => [(k, a)] -> Map k a #
O(n*log n). Build a map from a list of key/value pairs. See also fromAscList
.
If the list contains more than one value for the same key, the last value
for the key is retained.
If the keys of the list are ordered, linear-time implementation is used,
with the performance equal to fromDistinctAscList
.
fromList [] == empty fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")] fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
traverseWithKey :: Applicative t => (k -> a -> t b) -> Map k a -> t (Map k b) #
O(n).
That is, behaves exactly like a regular traverseWithKey
f m == fromList
$ traverse
((k, v) -> (,) k $ f k v) (toList
m)traverse
except that the traversing
function also has access to the key associated with a value.
traverseWithKey (\k v -> if odd k then Just (succ v) else Nothing) (fromList [(1, 'a'), (5, 'e')]) == Just (fromList [(1, 'b'), (5, 'f')]) traverseWithKey (\k v -> if odd k then Just (succ v) else Nothing) (fromList [(2, 'c')]) == Nothing
adjust :: Ord k => (a -> a) -> k -> Map k a -> Map k a #
O(log n). Update a value at a specific key with the result of the provided function. When the key is not a member of the map, the original map is returned.
adjust ("new " ++) 5 (fromList [(5,"a"), (3,"b")]) == fromList [(3, "b"), (5, "new a")] adjust ("new " ++) 7 (fromList [(5,"a"), (3,"b")]) == fromList [(3, "b"), (5, "a")] adjust ("new " ++) 7 empty == empty
insert :: Ord k => k -> a -> Map k a -> Map k a #
O(log n). Insert a new key and value in the map.
If the key is already present in the map, the associated value is
replaced with the supplied value. insert
is equivalent to
.insertWith
const
insert 5 'x' (fromList [(5,'a'), (3,'b')]) == fromList [(3, 'b'), (5, 'x')] insert 7 'x' (fromList [(5,'a'), (3,'b')]) == fromList [(3, 'b'), (5, 'a'), (7, 'x')] insert 5 'x' empty == singleton 5 'x'
lookup :: Ord k => k -> Map k a -> Maybe a #
O(log n). Lookup the value at a key in the map.
The function will return the corresponding value as (
,
or Just
value)Nothing
if the key isn't in the map.
An example of using lookup
:
import Prelude hiding (lookup) import Data.Map employeeDept = fromList([("John","Sales"), ("Bob","IT")]) deptCountry = fromList([("IT","USA"), ("Sales","France")]) countryCurrency = fromList([("USA", "Dollar"), ("France", "Euro")]) employeeCurrency :: String -> Maybe String employeeCurrency name = do dept <- lookup name employeeDept country <- lookup dept deptCountry lookup country countryCurrency main = do putStrLn $ "John's currency: " ++ (show (employeeCurrency "John")) putStrLn $ "Pete's currency: " ++ (show (employeeCurrency "Pete"))
The output of this program:
John's currency: Just "Euro" Pete's currency: Nothing
A Map from keys k

extsEnabled :: Q [Extension] #
List all enabled language extensions.
isExtEnabled :: Extension -> Q Bool #
Determine whether the given language extension is enabled in the Q
monad.
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.
isInstance :: Name -> [Type] -> Q Bool #
Is the list of instances returned by reifyInstances
nonempty?
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.
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
.
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.
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
.
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.
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
.
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
.
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.
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.
Recover from errors raised by reportError
or fail
.
reportWarning :: String -> Q () #
Report a warning to the user, and carry on.
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
.
report :: Bool -> String -> Q () #
Report an error (True) or warning (False),
but carry on; use fail
to stop.

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.

Unlike SourceStrictness

, DecidedStrictness
refers to the strictness that the compiler chooses for a data constructor
field, which may be different from what is written in source code. See
reifyConStrictness
for more information.
Instances
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 theForallC
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 theForallC
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
.

Defined in Language.Haskell.TH.Syntax type Rep AnnLookup = D1 (MetaData "AnnLookup" "Language.Haskell.TH.Syntax" "template-haskell" False) (C1 (MetaCons "AnnLookupModule" PrefixI False) (S1 (MetaSel (Nothing :: Maybe Symbol) NoSourceUnpackedness NoSourceStrictness DecidedLazy) (Rec0 Module)) :+: C1 (MetaCons "AnnLookupName" PrefixI False) (S1 (MetaSel (Nothing :: Maybe Symbol) NoSourceUnpackedness NoSourceStrictness DecidedLazy) (Rec0 Name))) |
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
.
