Synopsis

Documentation

trace :: String -> a -> a #

The trace function outputs the trace message given as its first argument, before returning the second argument as its result.

For example, this returns the value of f x but first outputs the message.

>>> let x = 123; f = show
>>> trace ("calling f with x = " ++ show x) (f x)
"calling f with x = 123
123"

The trace function should only be used for debugging, or for monitoring execution. The function is not referentially transparent: its type indicates that it is a pure function but it has the side effect of outputting the trace message.

class Monad m => MonadFix (m :: Type -> Type) where #

Monads having fixed points with a 'knot-tying' semantics. Instances of MonadFix should satisfy the following laws:

Purity
mfix (return . h) = return (fix h)
Left shrinking (or Tightening)
mfix (\x -> a >>= \y -> f x y) = a >>= \y -> mfix (\x -> f x y)
Sliding
mfix (liftM h . f) = liftM h (mfix (f . h)), for strict h.
Nesting
mfix (\x -> mfix (\y -> f x y)) = mfix (\x -> f x x)

This class is used in the translation of the recursive do notation supported by GHC and Hugs.

Methods

mfix :: (a -> m a) -> m a #

The fixed point of a monadic computation. mfix f executes the action f only once, with the eventual output fed back as the input. Hence f should not be strict, for then mfix f would diverge.

class Functor f => Applicative (f :: Type -> Type) where #

A functor with application, providing operations to

  • embed pure expressions (pure), and
  • sequence computations and combine their results (<*> and liftA2).

A minimal complete definition must include implementations of pure and of either <*> or liftA2. If it defines both, then they must behave the same as their default definitions:

(<*>) = liftA2 id
liftA2 f x y = f <$> x <*> y

Further, any definition must satisfy the following:

Identity
pure id <*> v = v
Composition
pure (.) <*> u <*> v <*> w = u <*> (v <*> w)
Homomorphism
pure f <*> pure x = pure (f x)
Interchange
u <*> pure y = pure ($ y) <*> u

The other methods have the following default definitions, which may be overridden with equivalent specialized implementations:

As a consequence of these laws, the Functor instance for f will satisfy

It may be useful to note that supposing

forall x y. p (q x y) = f x . g y

it follows from the above that

liftA2 p (liftA2 q u v) = liftA2 f u . liftA2 g v

If f is also a Monad, it should satisfy

(which implies that pure and <*> satisfy the applicative functor laws).

Minimal complete definition

pure, ((<*>) | liftA2)

Methods

pure :: a -> f a #

Lift a value.

(<*>) :: f (a -> b) -> f a -> f b infixl 4 #

Sequential application.

A few functors support an implementation of <*> that is more efficient than the default one.

Using ApplicativeDo: 'fs <*> as' can be understood as the do expression

do f <- fs
   a <- as
   pure (f a)

liftA2 :: (a -> b -> c) -> f a -> f b -> f c #

Lift a binary function to actions.

Some functors support an implementation of liftA2 that is more efficient than the default one. In particular, if fmap is an expensive operation, it is likely better to use liftA2 than to fmap over the structure and then use <*>.

This became a typeclass method in 4.10.0.0. Prior to that, it was a function defined in terms of <*> and fmap.

Using ApplicativeDo: 'liftA2 f as bs' can be understood as the do expression

do a <- as
   b <- bs
   pure (f a b)

(*>) :: f a -> f b -> f b infixl 4 #

Sequence actions, discarding the value of the first argument.

'as *> bs' can be understood as the do expression

do as
   bs

This is a tad complicated for our ApplicativeDo extension which will give it a Monad constraint. For an Applicative constraint we write it of the form

do _ <- as
   b <- bs
   pure b

(<*) :: f a -> f b -> f a infixl 4 #

Sequence actions, discarding the value of the second argument.

Using ApplicativeDo: 'as <* bs' can be understood as the do expression

do a <- as
   bs
   pure a

data Plugin #

Plugin is the compiler plugin data type. Try to avoid constructing one of these directly, and just modify some fields of defaultPlugin instead: this is to try and preserve source-code compatibility when we add fields to this.

Nonetheless, this API is preliminary and highly likely to change in the future.

Plugin 

Fields

class Monad m => MonadIO (m :: Type -> Type) where #

Monads in which IO computations may be embedded. Any monad built by applying a sequence of monad transformers to the IO monad will be an instance of this class.

Instances should satisfy the following laws, which state that liftIO is a transformer of monads:

Methods

liftIO :: IO a -> m a #

Lift a computation from the IO monad.

Methods

(==) :: IORef a -> IORef a -> Bool #

(/=) :: IORef a -> IORef a -> Bool #

foldlM :: (Foldable t, Monad m) => (b -> a -> m b) -> b -> t a -> m b #

Monadic fold over the elements of a structure, associating to the left, i.e. from left to right.

foldrM :: (Foldable t, Monad m) => (a -> b -> m b) -> b -> t a -> m b #

Monadic fold over the elements of a structure, associating to the right, i.e. from right to left.

(<$>) :: Functor f => (a -> b) -> f a -> f b infixl 4 #

An infix synonym for fmap.

The name of this operator is an allusion to $. Note the similarities between their types:

 ($)  ::              (a -> b) ->   a ->   b
(<$>) :: Functor f => (a -> b) -> f a -> f b

Whereas $ is function application, <$> is function application lifted over a Functor.

Examples

Expand

Convert from a Maybe Int to a Maybe String using show:

>>> show <$> Nothing
Nothing
>>> show <$> Just 3
Just "3"

Convert from an Either Int Int to an Either Int String using show:

>>> show <$> Left 17
Left 17
>>> show <$> Right 17
Right "17"

Double each element of a list:

>>> (*2) <$> [1,2,3]
[2,4,6]

Apply even to the second element of a pair:

>>> even <$> (2,2)
(2,True)

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.

getEvBindsTcPluginM :: TcPluginM EvBindsVar #

Access the EvBindsVar carried by the TcPluginM during constraint solving. Returns Nothing if invoked during tcPluginInit or tcPluginStop.

unsafeTcPluginTcM :: TcM a -> TcPluginM a #

This function provides an escape for direct access to the TcM monad. It should not be used lightly, and the provided TcPluginM API should be favoured instead.

hasCompleteSig :: TcSigFun -> Name -> Bool #

No signature or a partial signature

plusImportAvails :: ImportAvails -> ImportAvails -> ImportAvails #

Union two ImportAvails

This function is a key part of Import handling, basically for each import we create a separate ImportAvails structure and then union them all together with this function.

data NameShape #

A NameShape is a substitution on Names that can be used to refine the identities of a hole while we are renaming interfaces (see RnModIface). Specifically, a NameShape for ns_module_name A, defines a mapping from {A.T} (for some OccName T) to some arbitrary other Name.

The most intruiging thing about a NameShape, however, is how it's constructed. A NameShape is *implied* by the exported AvailInfos of the implementor of an interface: if an implementor of signature H exports M.T, you implicitly define a substitution from {H.T} to M.T. So a NameShape is computed from the list of AvailInfos that are exported by the implementation of a module, or successively merged together by the export lists of signatures which are joining together.

It's not the most obvious way to go about doing this, but it does seem to work!

NB: Can't boot this and put it in NameShape because then we start pulling in too many DynFlags things.

FrontendResult describes the result of running the frontend of a Haskell module. Usually, you'll get a FrontendTypecheck, since running the frontend involves typechecking a program, but for an hs-boot merge you'll just get a ModIface, since no actual typechecking occurred.

This data type really should be in HscTypes, but it needs to have a TcGblEnv which is only defined here.

data TcGblEnv #

TcGblEnv describes the top-level of the module at the point at which the typechecker is finished work. It is this structure that is handed on to the desugarer For state that needs to be updated during the typechecking phase and returned at end, use a TcRef (= IORef).

  • when figuring out what things are really unused

ImportAvails 

Fields

  • imp_mods :: ImportedMods

    Domain is all directly-imported modules

    See the documentation on ImportedModsVal in HscTypes for the meaning of the fields.

    We need a full ModuleEnv rather than a ModuleNameEnv here, because we might be importing modules of the same name from different packages. (currently not the case, but might be in the future).

  • imp_dep_mods :: ModuleNameEnv (ModuleName, IsBootInterface)

    Home-package modules needed by the module being compiled

    It doesn't matter whether any of these dependencies are actually used when compiling the module; they are listed if they are below it at all. For example, suppose M imports A which imports X. Then compiling M might not need to consult X.hi, but X is still listed in M's dependencies.

  • imp_dep_pkgs :: Set InstalledUnitId

    Packages needed by the module being compiled, whether directly, or via other modules in this package, or via modules imported from other packages.

  • imp_trust_pkgs :: Set InstalledUnitId

    This is strictly a subset of imp_dep_pkgs and records the packages the current module needs to trust for Safe Haskell compilation to succeed. A package is required to be trusted if we are dependent on a trustworthy module in that package. While perhaps making imp_dep_pkgs a tuple of (UnitId, Bool) where True for the bool indicates the package is required to be trusted is the more logical design, doing so complicates a lot of code not concerned with Safe Haskell. See Note [RnNames . Tracking Trust Transitively]

  • imp_trust_own_pkg :: Bool

    Do we require that our own package is trusted? This is to handle efficiently the case where a Safe module imports a Trustworthy module that resides in the same package as it. See Note [RnNames . Trust Own Package]

  • imp_orphs :: [Module]

    Orphan modules below us in the import tree (and maybe including us for imported modules)

  • imp_finsts :: [Module]

    Family instance modules below us in the import tree (and maybe including us for imported modules)

findPluginModule :: HscEnv -> ModuleName -> IO FindResult #

Locate a plugin module requested by the user, for a compiler plugin. This consults the same set of exposed packages as findImportedModule, unless -hide-all-plugin-packages or -plugin-package are specified.

findImportedModule :: HscEnv -> ModuleName -> Maybe FastString -> IO FindResult #

Locate a module that was imported by the user. We have the module's name, and possibly a package name. Without a package name, this function will use the search path and the known exposed packages to find the module, if a package is specified then only that package is searched for the module.

type LInjectivityAnn pass = Located (InjectivityAnn pass) #

Located Injectivity Annotation

data InjectivityAnn pass #

If the user supplied an injectivity annotation it is represented using InjectivityAnn. At the moment this is a single injectivity condition - see Note [Injectivity annotation]. `Located name` stores the LHS of injectivity condition. `[Located name]` stores the RHS of injectivity condition. Example:

type family Foo a b c = r | r -> a c where ...

This will be represented as "InjectivityAnn r [a, c]"

FunBind

Function-like Binding

FunBind is used for both functions f x = e and variables f = x -> e and strict variables !x = x + 1

Reason 1: Special case for type inference: see tcMonoBinds.

Reason 2: Instance decls can only have FunBinds, which is convenient. If you change this, you'll need to change e.g. rnMethodBinds

But note that the form f :: a->a = ... parses as a pattern binding, just like (f :: a -> a) = ...

Strict bindings have their strictness recorded in the SrcStrictness of their MatchContext. See Note [FunBind vs PatBind] for details about the relationship between FunBind and PatBind.

AnnKeywordIds

Fields

  • fun_ext :: XFunBind idL idR

    After the renamer, this contains the locally-bound free variables of this defn. See Note [Bind free vars]

  • fun_id :: Located (IdP idL)
     
  • fun_matches :: MatchGroup idR (LHsExpr idR)

    The payload

  • fun_co_fn :: HsWrapper

    Coercion from the type of the MatchGroup to the type of the Id. Example:

         f :: Int -> forall a. a -> a
         f x y = y
    

    Then the MatchGroup will have type (Int -> a' -> a') (with a free type variable a'). The coercion will take a CoreExpr of this type and convert it to a CoreExpr of type Int -> forall a'. a' -> a' Notice that the coercion captures the free a'.

  • fun_tick :: [Tickish Id]

    Ticks to put on the rhs, if any

PatBind

Pattern Binding

The pattern is never a simple variable; That case is done by FunBind. See Note [FunBind vs PatBind] for details about the relationship between FunBind and PatBind.

Located Signature

data Sig pass #

Signatures and pragmas

Constructors

TypeSig (XTypeSig pass) [Located (IdP pass)] (LHsSigWcType pass)

An ordinary type signature

f :: Num a => a -> a

After renaming, this list of Names contains the named wildcards brought into scope by this signature. For a signature _ -> _a -> Bool, the renamer will leave the unnamed wildcard _ untouched, and the named wildcard _a is then replaced with fresh meta vars in the type. Their names are stored in the type signature that brought them into scope, in this third field to be more specific.

PatSynSig (XPatSynSig pass) [Located (IdP pass)] (LHsSigType pass)

A pattern synonym type signature

pattern Single :: () => (Show a) => a -> [a]
ClassOpSig (XClassOpSig pass) Bool [Located (IdP pass)] (LHsSigType pass)

A signature for a class method False: ordinary class-method signature True: generic-default class method signature e.g. class C a where op :: a -> a -- Ordinary default op :: Eq a => a -> a -- Generic default No wildcards allowed here

IdSig (XIdSig pass) Id

A type signature in generated code, notably the code generated for record selectors. We simply record the desired Id itself, replete with its name, type and IdDetails. Otherwise it's just like a type signature: there should be an accompanying binding

FixSig (XFixSig pass) (FixitySig pass)

An ordinary fixity declaration

    infixl 8 ***
InlineSig (XInlineSig pass) (Located (IdP pass)) InlinePragma

An inline pragma

{#- INLINE f #-}
SpecSig (XSpecSig pass) (Located (IdP pass)) [LHsSigType pass] InlinePragma

A specialisation pragma

{-# SPECIALISE f :: Int -> Int #-}
SpecInstSig (XSpecInstSig pass) SourceText (LHsSigType pass)

A specialisation pragma for instance declarations only

{-# SPECIALISE instance Eq [Int] #-}

(Class tys); should be a specialisation of the current instance declaration

MinimalSig (XMinimalSig pass) SourceText (LBooleanFormula (Located (IdP pass)))

A minimal complete definition pragma

{-# MINIMAL a | (b, c | (d | e)) #-}
SCCFunSig (XSCCFunSig pass) SourceText (Located (IdP pass)) (Maybe (Located StringLiteral))

A "set cost centre" pragma for declarations

{-# SCC funName #-}

or

{-# SCC funName "cost_centre_name" #-}
CompleteMatchSig (XCompleteMatchSig pass) SourceText (Located [Located (IdP pass)]) (Maybe (Located (IdP pass)))

A complete match pragma

{-# COMPLETE C, D [:: T] #-}

Used to inform the pattern match checker about additional complete matchings which, for example, arise from pattern synonym definitions.

Create a Coercion that unwraps an implicit-parameter or overloaded-label dictionary to expose the underlying value. We expect the Type to have the form `IP sym ty` or `IsLabel sym ty`, and return a Coercion `co :: IP sym ty ~ ty` or `co :: IsLabel sym ty ~ Proxy# sym -> ty`. See also Note [Type-checking overloaded labels] in TcExpr.

evId :: EvId -> EvExpr #

Any sort of evidence Id, including coercions

foldEvBindMap :: (EvBind -> a -> a) -> a -> EvBindMap -> a #

isErasableHsWrapper :: HsWrapper -> Bool #

Is the wrapper erasable, i.e., will not affect runtime semantics?

maybeTcSubCo :: EqRel -> TcCoercion -> TcCoercion #

If the EqRel is ReprEq, makes a SubCo; otherwise, does nothing. Note that the input coercion should always be nominal.

isTcReflexiveCo :: TcCoercion -> Bool #

This version does a slow check, calculating the related types and seeing if they are equal.

parenthesizeHsContext :: forall (p :: Pass). PprPrec -> LHsContext (GhcPass p) -> LHsContext (GhcPass p) #

parenthesizeHsContext p ctxt checks if ctxt is a single constraint c such that hsTypeNeedsParens p c is true, and if so, surrounds c with an HsParTy to form a parenthesized ctxt. Otherwise, it simply returns ctxt unchanged.

parenthesizeHsType :: forall (p :: Pass). PprPrec -> LHsType (GhcPass p) -> LHsType (GhcPass p) #

parenthesizeHsType p ty checks if hsTypeNeedsParens p ty is true, and if so, surrounds ty with an HsParTy. Otherwise, it simply returns ty.

hsTypeNeedsParens :: PprPrec -> HsType pass -> Bool #

hsTypeNeedsParens p t returns True if the type t needs parentheses under precedence p.

pprHsExplicitForAll :: forall (p :: Pass). OutputableBndrId p => ForallVisFlag -> Maybe [LHsTyVarBndr (GhcPass p)] -> SDoc #

Version of pprHsForAll or pprHsForAllExtra that will always print forall. when passed Just []. Prints nothing if passed Nothing

pprHsForAllExtra :: forall (p :: Pass). OutputableBndrId p => Maybe SrcSpan -> ForallVisFlag -> [LHsTyVarBndr (GhcPass p)] -> LHsContext (GhcPass p) -> SDoc #

Version of pprHsForAll that can also print an extra-constraints wildcard, e.g. _ => a -> Bool or (Show a, _) => a -> String. This underscore will be printed when the 'Maybe SrcSpan' argument is a Just containing the location of the extra-constraints wildcard. A special function for this is needed, as the extra-constraints wildcard is removed from the actual context and type, and stored in a separate field, thus just printing the type will not print the extra-constraints wildcard.

pprHsForAll :: forall (p :: Pass). OutputableBndrId p => ForallVisFlag -> [LHsTyVarBndr (GhcPass p)] -> LHsContext (GhcPass p) -> SDoc #

Prints a forall; When passed an empty list, prints forall ./forall -> only when -dppr-debug is enabled.

splitLHsInstDeclTy :: LHsSigType GhcRn -> ([Name], LHsContext GhcRn, LHsType GhcRn) #

Decompose a type class instance type (of the form forall tvs. context => instance_head) into its constituent parts.

Note that this function looks through parentheses, so it will work on types such as (forall tvs. ...). The downside to this is that it is not generally possible to take the returned types and reconstruct the original type (parentheses and all) from them.

splitLHsQualTy :: LHsType pass -> (LHsContext pass, LHsType pass) #

Decompose a type of the form context => body into its constituent parts.

Note that this function looks through parentheses, so it will work on types such as (context => ...). The downside to this is that it is not generally possible to take the returned types and reconstruct the original type (parentheses and all) from them.

splitLHsForAllTyInvis :: LHsType pass -> ([LHsTyVarBndr pass], LHsType pass) #

Decompose a type of the form forall tvs. body into its constituent parts. Note that only invisible foralls (i.e., forall a., with a dot) are split apart; visible foralls (i.e., forall a ->, with an arrow) are left untouched.

This function is used to split apart certain types, such as instance declaration types, which disallow visible foralls. For instance, if GHC split apart the forall in instance forall a -> Show (Blah a), then that declaration would mistakenly be accepted!

Note that this function looks through parentheses, so it will work on types such as (forall a. ...). The downside to this is that it is not generally possible to take the returned types and reconstruct the original type (parentheses and all) from them.

splitLHsSigmaTyInvis :: LHsType pass -> ([LHsTyVarBndr pass], LHsContext pass, LHsType pass) #

Decompose a sigma type (of the form forall tvs. context => body) into its constituent parts. Note that only invisible foralls (i.e., forall a., with a dot) are split apart; visible foralls (i.e., forall a ->, with an arrow) are left untouched.

This function is used to split apart certain types, such as instance declaration types, which disallow visible foralls. For instance, if GHC split apart the forall in instance forall a -> Show (Blah a), then that declaration would mistakenly be accepted!

splitLHsPatSynTy :: LHsType pass -> ([LHsTyVarBndr pass], LHsContext pass, [LHsTyVarBndr pass], LHsContext pass, LHsType pass) #

Decompose a pattern synonym type signature into its constituent parts.

Note that this function looks through parentheses, so it will work on types such as (forall a. ...). The downside to this is that it is not generally possible to take the returned types and reconstruct the original type (parentheses and all) from them.

mkSumTy :: [Type] -> Type #

mkTupleTy1 :: Boxity -> [Type] -> Type #

Make a tuple type. The list of types should not include any RuntimeRep specifications. Boxed 1-tuples are *not* flattened. See Note [One-tuples] and Note [Don't flatten tuples from HsSyn] in MkCore

mkTupleTy :: Boxity -> [Type] -> Type #

sumTyCon :: Arity -> TyCon #

Type constructor for n-ary unboxed sum.

cTupleTyConNameArity_maybe :: Name -> Maybe Arity #

If the given name is that of a constraint tuple, return its arity. Note that this is inefficient.

isBuiltInOcc_maybe :: OccName -> Maybe Name #

Built-in syntax isn't "in scope" so these OccNames map to wired-in Names with BuiltInSyntax. However, this should only be necessary while resolving names produced by Template Haskell splices since we take care to encode built-in syntax names specially in interface files. See Note [Symbol table representation of names].

Moreover, there is no need to include names of things that the user can't write (e.g. type representation bindings like $tc(,,,)).

tyConAppNeedsKindSig #

Arguments

:: Bool

Should specified binders count towards injective positions in the kind of the TyCon? (If you're using visible kind applications, then you want True here.

-> TyCon 
-> Int

The number of args the TyCon is applied to.

-> Bool

Does T t_1 ... t_n need a kind signature? (Where n is the number of arguments)

Does a TyCon (that is applied to some number of arguments) need to be ascribed with an explicit kind signature to resolve ambiguity if rendered as a source-syntax type? (See Note [When does a tycon application need an explicit kind signature?] for a full explanation of what this function checks for.)

classifiesTypeWithValues :: Kind -> Bool #

Does this classify a type allowed to have values? Responds True to things like *, #, TYPE Lifted, TYPE v, Constraint.

True of any sub-kind of OpenTypeKind

isKindLevPoly :: Kind -> Bool #

Tests whether the given kind (which should look like TYPE x) is something other than a constructor tree (that is, constructors at every node). E.g. True of TYPE k, TYPE (F Int) False of TYPE 'LiftedRep

splitVisVarsOfType :: Type -> Pair TyCoVarSet #

Retrieve the free variables in this type, splitting them based on whether they are used visibly or invisibly. Invisible ones come first.

synTyConResKind :: TyCon -> Kind #

Find the result Kind of a type synonym, after applying it to its arity number of type variables Actually this function works fine on data types too, but they'd always return *, so we never need to ask

tyConsOfType :: Type -> UniqSet TyCon #

All type constructors occurring in the type; looking through type synonyms, but not newtypes. When it finds a Class, it returns the class TyCon.

resultIsLevPoly :: Type -> Bool #

Looking past all pi-types, is the end result potentially levity polymorphic? Example: True for (forall r (a :: TYPE r). String -> a) Example: False for (forall r1 r2 (a :: TYPE r1) (b :: TYPE r2). a -> b -> Type)

isTypeLevPoly :: Type -> Bool #

Returns True if a type is levity polymorphic. Should be the same as (isKindLevPoly . typeKind) but much faster. Precondition: The type has kind (TYPE blah)

tcIsRuntimeTypeKind :: Kind -> Bool #

Is this kind equivalent to TYPE r (for some unknown r)?

This considers Constraint to be distinct from *.

tcIsLiftedTypeKind :: Kind -> Bool #

Is this kind equivalent to *?

This considers Constraint to be distinct from *. For a version that treats them as the same type, see isLiftedTypeKind.

nonDetCmpTc :: TyCon -> TyCon -> Ordering #

Compare two TyCons. NB: This should never see Constraint (as recognized by Kind.isConstraintKindCon) which is considered a synonym for Type in Core. See Note [Kind Constraint and kind Type] in Kind. See Note [nonDetCmpType nondeterminism]

eqTypes :: [Type] -> [Type] -> Bool #

Type equality on lists of types, looking through type synonyms but not newtypes.

eqTypeX :: RnEnv2 -> Type -> Type -> Bool #

Compare types with respect to a (presumably) non-empty RnEnv2.

seqTypes :: [Type] -> () #

seqType :: Type -> () #

isValidJoinPointType :: JoinArity -> Type -> Bool #

Determine whether a type could be the type of a join point of given total arity, according to the polymorphism rule. A join point cannot be polymorphic in its return type, since given join j a b x y z = e1 in e2, the types of e1 and e2 must be the same, and a and b are not in scope for e2. (See Note [The polymorphism rule of join points] in CoreSyn.) Returns False also if the type simply doesn't have enough arguments.

Note that we need to know how many arguments (type *and* value) the putative join point takes; for instance, if j :: forall a. a -> Int then j could be a binary join point returning an Int, but it could *not* be a unary join point returning a -> Int.

TODO: See Note [Excess polymorphism and join points]

isPrimitiveType :: Type -> Bool #

Returns true of types that are opaque to Haskell.

isStrictType :: HasDebugCallStack => Type -> Bool #

Computes whether an argument (or let right hand side) should be computed strictly or lazily, based only on its type. Currently, it's just isUnliftedType. Panics on levity-polymorphic types.

isDataFamilyAppType :: Type -> Bool #

Check whether a type is a data family type

isAlgType :: Type -> Bool #

See Type for what an algebraic type is. Should only be applied to types, as opposed to e.g. partially saturated type constructors

getRuntimeRep :: HasDebugCallStack => Type -> Type #

Extract the RuntimeRep classifier of a type. For instance, getRuntimeRep_maybe Int = LiftedRep. Panics if this is not possible.

getRuntimeRep_maybe :: HasDebugCallStack => Type -> Maybe Type #

Extract the RuntimeRep classifier of a type. For instance, getRuntimeRep_maybe Int = LiftedRep. Returns Nothing if this is not possible.

dropRuntimeRepArgs :: [Type] -> [Type] #

Drops prefix of RuntimeRep constructors in TyConApps. Useful for e.g. dropping 'LiftedRep arguments of unboxed tuple TyCon applications:

dropRuntimeRepArgs [ 'LiftedRep, 'IntRep , String, Int]

isRuntimeRepKindedTy :: Type -> Bool #

Is this a type of kind RuntimeRep? (e.g. LiftedRep)

mightBeUnliftedType :: Type -> Bool #

Returns:

  • False if the type is guaranteed lifted or
  • True if it is unlifted, OR we aren't sure (e.g. in a levity-polymorphic case)

isUnliftedType :: HasDebugCallStack => Type -> Bool #

See Type for what an unlifted type is. Panics on levity polymorphic types; See mightBeUnliftedType for a more approximate predicate that behaves better in the presence of levity polymorphism.

isLiftedType_maybe :: HasDebugCallStack => Type -> Maybe Bool #

Returns Just True if this type is surely lifted, Just False if it is surely unlifted, Nothing if we can't be sure (i.e., it is levity polymorphic), and panics if the kind does not have the shape TYPE r.

isCoVarType :: Type -> Bool #

Does this type classify a core (unlifted) Coercion? At either role nominal or representational (t1 ~ t2) See Note [Types for coercions, predicates, and evidence] in TyCoRep

coAxNthLHS :: forall (br :: BranchFlag). CoAxiom br -> Int -> Type #

Get the type on the LHS of a coercion induced by a type/data family instance.

mkFamilyTyConApp :: TyCon -> [Type] -> Type #

Given a family instance TyCon and its arg types, return the corresponding family type. E.g:

data family T a
data instance T (Maybe b) = MkT b

Where the instance tycon is :RTL, so:

mkFamilyTyConApp :RTL Int  =  T (Maybe Int)

closeOverKindsDSet :: DTyVarSet -> DTyVarSet #

Add the kind variables free in the kinds of the tyvars in the given set. Returns a deterministic set.

closeOverKindsList :: [TyVar] -> [TyVar] #

Add the kind variables free in the kinds of the tyvars in the given set. Returns a deterministically ordered list.

closeOverKindsFV :: [TyVar] -> FV #

Given a list of tyvars returns a deterministic FV computation that returns the given tyvars with the kind variables free in the kinds of the given tyvars.

closeOverKinds :: TyVarSet -> TyVarSet #

Add the kind variables free in the kinds of the tyvars in the given set. Returns a non-deterministic set.

binderRelevantType_maybe :: TyCoBinder -> Maybe Type #

Extract a relevant type, if there is one.

isAnonTyCoBinder :: TyCoBinder -> Bool #

Does this binder bind a variable that is not erased? Returns True for anonymous binders.

mkAnonBinder :: AnonArgFlag -> Type -> TyCoBinder #

Make an anonymous binder

appTyArgFlags :: Type -> [Type] -> [ArgFlag] #

Given a Type and a list of argument types to which the Type is applied, determine each argument's visibility (Inferred, Specified, or Required).

Most of the time, the arguments will be Required, but not always. Consider f :: forall a. a -> Type. In f Type Bool, the first argument (Type) is Specified and the second argument (Bool) is Required. It is precisely this sort of higher-rank situation in which appTyArgFlags comes in handy, since f Type Bool would be represented in Core using AppTys. (See also #15792).

tyConArgFlags :: TyCon -> [Type] -> [ArgFlag] #

Given a TyCon and a list of argument types to which the TyCon is applied, determine each argument's visibility (Inferred, Specified, or Required).

Wrinkle: consider the following scenario:

T :: forall k. k -> k
tyConArgFlags T [forall m. m -> m -> m, S, R, Q]

After substituting, we get

T (forall m. m -> m -> m) :: (forall m. m -> m -> m) -> forall n. n -> n -> n

Thus, the first argument is invisible, S is visible, R is invisible again, and Q is visible.

partitionInvisibles :: [(a, ArgFlag)] -> ([a], [a]) #

Given a list of things paired with their visibilities, partition the things into (invisible things, visible things).

filterOutInferredTypes :: TyCon -> [Type] -> [Type] #

Given a TyCon and a list of argument types, filter out any Inferred arguments.

filterOutInvisibleTypes :: TyCon -> [Type] -> [Type] #

Given a TyCon and a list of argument types, filter out any invisible (i.e., Inferred or Specified) arguments.

splitForAllVarBndrs :: Type -> ([TyCoVarBinder], Type) #

Like splitPiTys but split off only named binders and returns TyCoVarBinders rather than TyCoBinders

splitPiTys :: Type -> ([TyCoBinder], Type) #

Split off all TyCoBinders to a type, splitting both proper foralls and functions

splitPiTy :: Type -> (TyCoBinder, Type) #

Takes a forall type apart, or panics

splitPiTy_maybe :: Type -> Maybe (TyCoBinder, Type) #

Attempts to take a forall type apart; works with proper foralls and functions

splitForAllTy_co_maybe :: Type -> Maybe (TyCoVar, Type) #

Like splitForAllTy_maybe, but only returns Just if it is a covar binder.

splitForAllTy_ty_maybe :: Type -> Maybe (TyCoVar, Type) #

Like splitForAllTy_maybe, but only returns Just if it is a tyvar binder.

splitForAllTy_maybe :: Type -> Maybe (TyCoVar, Type) #

isFunTy :: Type -> Bool #

Is this a function?

isPiTy :: Type -> Bool #

Is this a function or forall?

isForAllTy_co :: Type -> Bool #

Like isForAllTy, but returns True only if it is a covar binder

isForAllTy_ty :: Type -> Bool #

Like isForAllTy, but returns True only if it is a tyvar binder

isForAllTy :: Type -> Bool #

Checks whether this is a proper forall (with a named binder)

splitForAllTysSameVis :: ArgFlag -> Type -> ([TyCoVar], Type) #

Like splitForAllTys, but only splits a ForAllTy if sameVis argf supplied_argf is True, where argf is the visibility of the ForAllTy's binder and supplied_argf is the visibility provided as an argument to this function.

splitForAllTys :: Type -> ([TyCoVar], Type) #

Take a ForAllTy apart, returning the list of tycovars and the result type. This always succeeds, even if it returns only an empty list. Note that the result type returned may have free variables that were bound by a forall.

mkTyConBindersPreferAnon #

Arguments

:: [TyVar]

binders

-> TyCoVarSet

free variables of result

-> [TyConBinder] 

Given a list of type-level vars and the free vars of a result kind, makes TyCoBinders, preferring anonymous binders if the variable is, in fact, not dependent. e.g. mkTyConBindersPreferAnon (k:*),(b:k),(c:k) We want (k:*) Named, (b:k) Anon, (c:k) Anon

All non-coercion binders are visible.

mkLamTypes :: [Var] -> Type -> Type #

mkLamType for multiple type or value arguments

mkLamType :: Var -> Type -> Type #

Makes a (->) type or an implicit forall type, depending on whether it is given a type variable or a term variable. This is used, for example, when producing the type of a lambda. Always uses Inferred binders.

Like mkForAllTys, but assumes all variables are dependent and Inferred, a common case

mkInvForAllTy :: TyVar -> Type -> Type #

Like mkTyCoInvForAllTy, but tv should be a tyvar

mkTyCoInvForAllTy :: TyCoVar -> Type -> Type #

Make a dependent forall over an Inferred variable

discardCast :: Type -> Type #

Drop the cast on a type, if any. If there is no cast, just return the original type. This is rarely what you want. The CastTy data constructor (in TyCoRep) has the invariant that another CastTy is not inside. See the data constructor for a full description of this invariant. Since CastTy cannot be nested, the result of discardCast cannot be a CastTy.

newTyConInstRhs :: TyCon -> [Type] -> Type #

Unwrap one layer of newtype on a type constructor and its arguments, using an eta-reduced version of the newtype if possible. This requires tys to have at least newTyConInstArity tycon elements.

splitListTyConApp_maybe :: Type -> Maybe Type #

Attempts to tease a list type apart and gives the type of the elements if successful (looks through type synonyms)

repSplitTyConApp_maybe :: HasDebugCallStack => Type -> Maybe (TyCon, [Type]) #

Like splitTyConApp_maybe, but doesn't look through synonyms. This assumes the synonyms have already been dealt with.

Moreover, for a FunTy, it only succeeds if the argument types have enough info to extract the runtime-rep arguments that the funTyCon requires. This will usually be true; but may be temporarily false during canonicalization: see Note [FunTy and decomposing tycon applications] in TcCanonical

tcSplitTyConApp_maybe :: HasCallStack => Type -> Maybe (TyCon, [Type]) #

Split a type constructor application into its type constructor and applied types. Note that this may fail in the case of a FunTy with an argument of unknown kind FunTy (e.g. FunTy (a :: k) Int. since the kind of a isn't of the form TYPE rep). Consequently, you may need to zonk your type before using this function.

If you only need the TyCon, consider using tcTyConAppTyCon_maybe.

splitTyConApp :: Type -> (TyCon, [Type]) #

Attempts to tease a type apart into a type constructor and the application of a number of arguments to that constructor. Panics if that is not possible. See also splitTyConApp_maybe

tyConAppArgs_maybe :: Type -> Maybe [Type] #

The same as snd . splitTyConApp

tyConAppTyCon_maybe :: Type -> Maybe TyCon #

The same as fst . splitTyConApp

tyConAppTyConPicky_maybe :: Type -> Maybe TyCon #

Retrieve the tycon heading this type, if there is one. Does not look through synonyms.

mkTyConApp :: TyCon -> [Type] -> Type #

A key function: builds a TyConApp or FunTy as appropriate to its arguments. Applies its arguments to the constructor from left to right.

applyTysX :: [TyVar] -> Type -> [Type] -> Type #

piResultTys :: HasDebugCallStack => Type -> [Type] -> Type #

(piResultTys f_ty [ty1, .., tyn]) gives the type of (f ty1 .. tyn) where f :: f_ty piResultTys is interesting because: 1. f_ty may have more for-alls than there are args 2. Less obviously, it may have fewer for-alls For case 2. think of: piResultTys (forall a.a) [forall b.b, Int] This really can happen, but only (I think) in situations involving undefined. For example: undefined :: forall a. a Term: undefined (forall b. b->b) Int This term should have type (Int -> Int), but notice that there are more type args than foralls in undefineds type.

funArgTy :: Type -> Type #

Just like piResultTys but for a single argument Try not to iterate piResultTy, because it's inefficient to substitute one variable at a time; instead use 'piResultTys"

Extract the function argument type and panic if that is not possible

funResultTy :: Type -> Type #

Extract the function result type and panic if that is not possible

splitFunTy_maybe :: Type -> Maybe (Type, Type) #

Attempts to extract the argument and result types from a type

splitFunTy :: Type -> (Type, Type) #

Attempts to extract the argument and result types from a type, and panics if that is not possible. See also splitFunTy_maybe

pprUserTypeErrorTy :: Type -> SDoc #

Render a type corresponding to a user type error into a SDoc.

userTypeError_maybe :: Type -> Maybe Type #

Is this type a custom user error? If so, give us the kind and the error message.

isLitTy :: Type -> Maybe TyLit #

Is this a type literal (symbol or numeric).

isStrLitTy :: Type -> Maybe FastString #

Is this a symbol literal. We also look through type synonyms.

isNumLitTy :: Type -> Maybe Integer #

Is this a numeric literal. We also look through type synonyms.

repSplitAppTys :: HasDebugCallStack => Type -> (Type, [Type]) #

Like splitAppTys, but doesn't look through type synonyms

splitAppTys :: Type -> (Type, [Type]) #

Recursively splits a type as far as is possible, leaving a residual type being applied to and the type arguments applied to it. Never fails, even if that means returning an empty list of type applications.

splitAppTy :: Type -> (Type, Type) #

Attempts to take a type application apart, as in splitAppTy_maybe, and panics if this is not possible

tcRepSplitAppTy_maybe :: Type -> Maybe (Type, Type) #

Does the AppTy split as in tcSplitAppTy_maybe, but assumes that any coreView stuff is already done. Refuses to look through (c => t)

repSplitAppTy_maybe :: HasDebugCallStack => Type -> Maybe (Type, Type) #

Does the AppTy split as in splitAppTy_maybe, but assumes that any Core view stuff is already done

splitAppTy_maybe :: Type -> Maybe (Type, Type) #

Attempt to take a type application apart, whether it is a function, type constructor, or plain type application. Note that type family applications are NEVER unsaturated by this!

mkAppTys :: Type -> [Type] -> Type #

repGetTyVar_maybe :: Type -> Maybe TyVar #

Attempts to obtain the type variable underlying a Type, without any expansion

getCastedTyVar_maybe :: Type -> Maybe (TyVar, CoercionN) #

If the type is a tyvar, possibly under a cast, returns it, along with the coercion. Thus, the co is :: kind tv ~N kind ty

getTyVar_maybe :: Type -> Maybe TyVar #

Attempts to obtain the type variable underlying a Type

getTyVar :: String -> Type -> TyVar #

Attempts to obtain the type variable underlying a Type, and panics with the given message if this is not a type variable type. See also getTyVar_maybe

mapCoercion :: Monad m => TyCoMapper env m -> env -> Coercion -> m Coercion #

mapType :: Monad m => TyCoMapper env m -> env -> Type -> m Type #

isRuntimeRepVar :: TyVar -> Bool #

Is a tyvar of type RuntimeRep?

isUnliftedTypeKind :: Kind -> Bool #

Returns True if the kind classifies unlifted types and False otherwise. Note that this returns False for levity-polymorphic kinds, which may be specialized to a kind that classifies unlifted types.

kindRep_maybe :: HasDebugCallStack => Kind -> Maybe Type #

Given a kind (TYPE rr), extract its RuntimeRep classifier rr. For example, kindRep_maybe * = Just LiftedRep Returns Nothing if the kind is not of form (TYPE rr) Treats * and Constraint as the same

kindRep :: HasDebugCallStack => Kind -> Type #

Extract the RuntimeRep classifier of a type from its kind. For example, kindRep * = LiftedRep; Panics if this is not possible. Treats * and Constraint as the same

expandTypeSynonyms :: Type -> Type #

Expand out all type synonyms. Actually, it'd suffice to expand out just the ones that discard type variables (e.g. type Funny a = Int) But we don't know which those are currently, so we just expand all.

expandTypeSynonyms only expands out type synonyms mentioned in the type, not in the kinds of any TyCon or TyVar mentioned in the type.

Keep this synchronized with synonymTyConsOfType

data TCvSubst #

Type & coercion substitution

The following invariants must hold of a TCvSubst:

  1. The in-scope set is needed only to guide the generation of fresh uniques
  2. In particular, the kind of the type variables in the in-scope set is not relevant
  3. The substitution is only applied ONCE! This is because in general such application will not reach a fixed point.

type TvSubstEnv = TyVarEnv Type #

A substitution of Types for TyVars and Kinds for KindVars

tidyTopType :: Type -> Type #

Calls tidyType on a top-level type (i.e. with an empty tidying environment)

tidyOpenTypes :: TidyEnv -> [Type] -> (TidyEnv, [Type]) #

Grabs the free type variables, tidies them and then uses tidyType to work over the type itself

tidyTypes :: TidyEnv -> [Type] -> [Type] #

tidyOpenTyCoVar :: TidyEnv -> TyCoVar -> (TidyEnv, TyCoVar) #

Treat a new TyCoVar as a binder, and give it a fresh tidy name using the environment if one has not already been allocated. See also tidyVarBndr

tidyFreeTyCoVars :: TidyEnv -> [TyCoVar] -> TidyEnv #

Add the free TyVars to the env in tidy form, so that we can tidy the type they are free in

tidyVarBndrs :: TidyEnv -> [TyCoVar] -> (TidyEnv, [TyCoVar]) #

This tidies up a type for printing in an error message, or in an interface file.

It doesn't change the uniques at all, just the print names.

tyCoVarsOfTypesWellScoped :: [Type] -> [TyVar] #

Get the free vars of types in scoped order

tyCoVarsOfTypeWellScoped :: Type -> [TyVar] #

Get the free vars of a type in scoped order

scopedSort :: [TyCoVar] -> [TyCoVar] #

Do a topological sort on a list of tyvars, so that binders occur before occurrences E.g. given [ a::k, k::*, b::k ] it'll return a well-scoped list [ k::*, a::k, b::k ]

This is a deterministic sorting operation (that is, doesn't depend on Uniques).

It is also meant to be stable: that is, variables should not be reordered unnecessarily. This is specified in Note [ScopedSort] See also Note [Ordering of implicit variables] in RnTypes

noFreeVarsOfType :: Type -> Bool #

Returns True if this type has no free variables. Should be the same as isEmptyVarSet . tyCoVarsOfType, but faster in the non-forall case.

tyCoFVsOfType :: Type -> FV #

The worker for tyCoFVsOfType and tyCoFVsOfTypeList. The previous implementation used unionVarSet which is O(n+m) and can make the function quadratic. It's exported, so that it can be composed with other functions that compute free variables. See Note [FV naming conventions] in FV.

Eta-expanded because that makes it run faster (apparently) See Note [FV eta expansion] in FV for explanation.

tyCoVarsOfTypeDSet :: Type -> DTyCoVarSet #

tyCoFVsOfType that returns free variables of a type in a deterministic set. For explanation of why using VarSet is not deterministic see Note [Deterministic FV] in FV.

mkAppTy :: Type -> Type -> Type #

Applies a type to another, as in e.g. k a

mkCastTy :: Type -> Coercion -> Type #

Make a CastTy. The Coercion must be nominal. Checks the Coercion for reflexivity, dropping it if it's reflexive. See Note [Respecting definitional equality] in TyCoRep

eqType :: Type -> Type -> Bool #

Type equality on source types. Does not look through newtypes or PredTypes, but it does look through type synonyms. This first checks that the kinds of the types are equal and then checks whether the types are equal, ignoring casts and coercions. (The kind check is a recursive call, but since all kinds have type Type, there is no need to check the types of kinds.) See also Note [Non-trivial definitional equality] in TyCoRep.

coreView :: Type -> Maybe Type #

This function Strips off the top layer only of a type synonym application (if any) its underlying representation type. Returns Nothing if there is nothing to look through. This function considers Constraint to be a synonym of TYPE LiftedRep.

By being non-recursive and inlined, this case analysis gets efficiently joined onto the case analysis that the caller is already doing

tcView :: Type -> Maybe Type #

Gives the typechecker view of a type. This unwraps synonyms but leaves Constraint alone. c.f. coreView, which turns Constraint into TYPE LiftedRep. Returns Nothing if no unwrapping happens. See also Note [coreView vs tcView]

isRuntimeRepTy :: Type -> Bool #

data SyntaxExpr p #

Syntax Expression

SyntaxExpr is like PostTcExpr, but it's filled in a little earlier, by the renamer. It's used for rebindable syntax.

E.g. (>>=) is filled in before the renamer by the appropriate Name for (>>=), and then instantiated by the type checker with its type args etc

This should desugar to

syn_res_wrap $ syn_expr (syn_arg_wraps[0] arg0)
                        (syn_arg_wraps[1] arg1) ...

where the actual arguments come from elsewhere in the AST. This could be defined using GhcPass p and such, but it's harder to get it all to work out that way. (noSyntaxExpr is hard to write, for example.)

noExtCon :: NoExtCon -> a #

Eliminate a NoExtCon. Much like absurd.

noExtField :: NoExtField #

Used when constructing a term with an unused extension point.

data NoExtField #

A placeholder type for TTG extension points that are not currently unused to represent any particular value.

This should not be confused with NoExtCon, which are found in unused extension constructors and therefore should never be inhabited. In contrast, NoExtField is used in extension points (e.g., as the field of some constructor), so it must have an inhabitant to construct AST passes that manipulate fields with that extension point as their type.

data NoExtCon #

Used in TTG extension constructors that have yet to be extended with anything. If an extension constructor has NoExtCon as its field, it is not intended to ever be constructed anywhere, and any function that consumes the extension constructor can eliminate it by way of noExtCon.

This should not be confused with NoExtField, which are found in unused extension points (not constructors) and therefore can be inhabited.

class Convertable a b | a -> b where #

Conversion of annotations from one type index to another. This is required where the AST is converted from one pass to another, and the extension values need to be brought along if possible. So for example a SourceText is converted via id, but needs a type signature to keep the type checker happy.

Variable Binder

A TyCoVarBinder is the binder of a ForAllTy It's convenient to define this synonym here rather its natural home in TyCoRep, because it's used in DataCon.hs-boot

A TyVarBinder is a binder with only TyVar

mkBoxedTupleTy :: [Type] -> Type #

Build the type of a small tuple that holds the specified type of thing Flattens 1-tuples. See Note [One-tuples].

unboxedTupleKind :: [Type] -> Kind #

Specialization of unboxedTupleSumKind for tuples

mkPromotedListTy #

Arguments

:: Kind

of the elements of the list

-> [Type]

elements

-> Type 

Make a *promoted* list.

nameStableString :: Name -> String #

Get a string representation of a Name that's unique and stable across recompilations. Used for deterministic generation of binds for derived instances. eg. "$aeson_70dylHtv1FFGeai1IoxcQr$Data.Aeson.Types.Internal$String"

pprNameUnqualified :: Name -> SDoc #

Print the string of Name unqualifiedly directly.

stableNameCmp :: Name -> Name -> Ordering #

Compare Names lexicographically This only works for Names that originate in the source code or have been tidied.

localiseName :: Name -> Name #

Make the Name into an internal name, regardless of what it was to begin with

mkFCallName :: Unique -> String -> Name #

Make a name for a foreign call

mkSystemName :: Unique -> OccName -> Name #

Create a name brought into being by the compiler

mkWiredInName :: Module -> OccName -> Unique -> TyThing -> BuiltInSyntax -> Name #

Create a name which is actually defined by the compiler itself

mkExternalName :: Unique -> Module -> OccName -> SrcSpan -> Name #

Create a name which definitely originates in the given module

mkInternalName :: Unique -> OccName -> SrcSpan -> Name #

Create a name which is (for now at least) local to the current module and hence does not need a Module to disambiguate it from other Names

nameIsFromExternalPackage :: UnitId -> Name -> Bool #

Returns True if the Name comes from some other package: neither this package nor the interactive package.

nameIsLocalOrFrom :: Module -> Name -> Bool #

Returns True if the name is (a) Internal (b) External but from the specified module (c) External but from the interactive package

The key idea is that False means: the entity is defined in some other module you can find the details (type, fixity, instances) in some interface file those details will be stored in the EPT or HPT

True means: the entity is defined in this module or earlier in the GHCi session you can find details (type, fixity, instances) in the TcGblEnv or TcLclEnv

The isInteractiveModule part is because successive interactions of a GHCi session each give rise to a fresh module (Ghci1, Ghci2, etc), but they all come from the magic interactive package; and all the details are kept in the TcLclEnv, TcGblEnv, NOT in the HPT or EPT. See Note [The interactive package] in HscTypes

type PredType = Type #

A type of the form p of constraint kind represents a value whose type is the Haskell predicate p, where a predicate is what occurs before the => in a Haskell type.

We use PredType as documentation to mark those types that we guarantee to have this kind.

It can be expanded into its representation, but:

  • The type checker must treat it as opaque
  • The rest of the compiler treats it as transparent

Consider these examples:

f :: (Eq a) => a -> Int
g :: (?x :: Int -> Int) => a -> Int
h :: (r\l) => {r} => {l::Int | r}

Here the Eq a and ?x :: Int -> Int and rl are all called "predicates"

type Kind = Type #

The key type representing kinds in the compiler.

type ThetaType = [PredType] #

A collection of PredTypes

makeDynFlagsConsistent :: DynFlags -> (DynFlags, [Located String]) #

Resolve any internal inconsistencies in a set of DynFlags. Returns the consistent DynFlags as well as a list of warnings to report to the user.

canonicalizeHomeModule :: DynFlags -> ModuleName -> Module #

Given a ModuleName of a signature in the home library, find out how it is instantiated. E.g., the canonical form of A in p[A=q[]:A] is q[]:A.

rtsIsProfiled :: Bool #

Was the runtime system built with profiling enabled?

warningHierarchies :: [[String]] #

Warning group hierarchies, where there is an explicit inclusion relation.

Each inner list is a hierarchy of warning groups, ordered from smallest to largest, where each group is a superset of the one before it.

Separating this from warningGroups allows for multiple hierarchies with no inherent relation to be defined.

The special-case Weverything group is not included.

warningGroups :: [(String, [WarningFlag])] #

Warning groups.

As all warnings are in the Weverything set, it is ignored when displaying to the user which group a warning is in.

xFlags :: [FlagSpec Extension] #

fLangFlags :: [FlagSpec Extension] #

These -f<blah> flags can all be reversed with -fno-<blah>

fFlags :: [FlagSpec GeneralFlag] #

wWarningFlags :: [FlagSpec WarningFlag] #

These -W<blah> flags can all be reversed with -Wno-<blah>

flagsForCompletion :: Bool -> [String] #

Make a list of flags for shell completion. Filter all available flags into two groups, for interactive GHC vs all other.

allNonDeprecatedFlags :: [String] #

All dynamic flags option strings without the deprecated ones. These are the user facing strings for enabling and disabling options.

putLogMsg :: DynFlags -> WarnReason -> Severity -> SrcSpan -> PprStyle -> MsgDoc -> IO () #

Write an error or warning to the LogOutput.

parseDynamicFlagsFull #

Arguments

:: MonadIO m 
=> [Flag (CmdLineP DynFlags)]

valid flags to match against

-> Bool

are the arguments from the command line?

-> DynFlags

current dynamic flags

-> [Located String]

arguments to parse

-> m (DynFlags, [Located String], [Warn]) 

Parses the dynamically set flags for GHC. This is the most general form of the dynamic flag parser that the other methods simply wrap. It allows saying which flags are valid flags and indicating if we are parsing arguments from the command line or from a file pragma.

parseDynamicFilePragma #

Arguments

:: MonadIO m 
=> DynFlags 
-> [Located String] 
-> m (DynFlags, [Located String], [Warn])

Updated DynFlags, left-over arguments, and list of warnings.

Like parseDynamicFlagsCmdLine but does not allow the package flags (-package, -hide-package, -ignore-package, -hide-all-packages, -package-db). Used to parse flags set in a modules pragma.

parseDynamicFlagsCmdLine #

Arguments

:: MonadIO m 
=> DynFlags 
-> [Located String] 
-> m (DynFlags, [Located String], [Warn])

Updated DynFlags, left-over arguments, and list of warnings.

Parse dynamic flags from a list of command line arguments. Returns the parsed DynFlags, the left-over arguments, and a list of warnings. Throws a UsageError if errors occurred during parsing (such as unknown flags or missing arguments).

updOptLevel :: Int -> DynFlags -> DynFlags #

Sets the DynFlags to be appropriate to the optimisation level

getVerbFlags :: DynFlags -> [String] #

Gets the verbosity flag for the current verbosity level. This is fed to other tools, so GHC-specific verbosity flags like -ddump-most are not included

getOpts #

Arguments

:: DynFlags

DynFlags to retrieve the options from

-> (DynFlags -> [a])

Relevant record accessor: one of the opt_* accessors

-> [a]

Correctly ordered extracted options

Retrieve the options corresponding to a particular opt_* field in the correct order

unsafeFlagsForInfer :: [(String, DynFlags -> SrcSpan, DynFlags -> Bool, DynFlags -> DynFlags)] #

A list of unsafe flags under Safe Haskell. Tuple elements are: * name of the flag * function to get srcspan that enabled the flag * function to test if the flag is on * function to turn the flag off

unsafeFlags :: [(String, DynFlags -> SrcSpan, DynFlags -> Bool, DynFlags -> DynFlags)] #

A list of unsafe flags under Safe Haskell. Tuple elements are: * name of the flag * function to get srcspan that enabled the flag * function to test if the flag is on * function to turn the flag off

safeImplicitImpsReq :: DynFlags -> Bool #

Are all implicit imports required to be safe for this Safe Haskell mode? Implicit imports are things in the prelude. e.g System.IO when print is used.

safeDirectImpsReq :: DynFlags -> Bool #

Are all direct imports required to be safe for this Safe Haskell mode? Direct imports are when the code explicitly imports a module

safeImportsOn :: DynFlags -> Bool #

Test if Safe Imports are on in some form

safeInferOn :: DynFlags -> Bool #

Is the Safe Haskell safe inference mode active

safeLanguageOn :: DynFlags -> Bool #

Is the Safe Haskell safe language in use

safeHaskellOn :: DynFlags -> Bool #

Is Safe Haskell on in some way (including inference mode)

packageTrustOn :: DynFlags -> Bool #

Is the -fpackage-trust mode on

dynFlagDependencies :: DynFlags -> [ModuleName] #

Some modules have dependencies on others through the DynFlags rather than textual imports

xopt_set_unlessExplSpec :: Extension -> (DynFlags -> Extension -> DynFlags) -> DynFlags -> DynFlags #

Set or unset a Extension, unless it has been explicitly set or unset before.

xopt :: Extension -> DynFlags -> Bool #

Test whether a Extension is set

wopt_set_fatal :: DynFlags -> WarningFlag -> DynFlags #

Mark a WarningFlag as fatal (do not set the flag)

wopt_fatal :: WarningFlag -> DynFlags -> Bool #

Test whether a WarningFlag is set as fatal

wopt :: WarningFlag -> DynFlags -> Bool #

Test whether a WarningFlag is set

gopt :: GeneralFlag -> DynFlags -> Bool #

Test whether a GeneralFlag is set

dopt :: DumpFlag -> DynFlags -> Bool #

Test whether a DumpFlag is set

languageExtensions :: Maybe Language -> [Extension] #

The language extensions implied by the various language variants. When updating this be sure to update the flag documentation in docsusers-guideglasgow_exts.rst.

defaultLogActionHPrintDoc :: DynFlags -> Handle -> SDoc -> PprStyle -> IO () #

Like defaultLogActionHPutStrDoc but appends an extra newline.

defaultDynFlags :: Settings -> LlvmConfig -> DynFlags #

The normal DynFlags. Note that they are not suitable for use in this form and must be fully initialized by runGhc first.

initDynFlags :: DynFlags -> IO DynFlags #

Used by runGhc to partially initialize a new DynFlags value

dynamicOutputFile :: DynFlags -> FilePath -> FilePath #

Compute the path of the dynamic object corresponding to an object file.

ifGeneratingDynamicToo :: MonadIO m => DynFlags -> m a -> m a -> m a #

whenGeneratingDynamicToo :: MonadIO m => DynFlags -> m () -> m () #

positionIndependent :: DynFlags -> Bool #

Are we building with -fPIE or -fPIC enabled?

targetRetainsAllBindings :: HscTarget -> Bool #

Does this target retain *all* top-level bindings for a module, rather than just the exported bindings, in the TypeEnv and compiled code (if any)? In interpreted mode we do this, so that GHCi can call functions inside a module. In HscNothing mode we also do it, so that Haddock can get access to the GlobalRdrEnv for a module after typechecking it.

isObjectTarget :: HscTarget -> Bool #

Will this target result in an object file on the disk?

versionedAppDir :: DynFlags -> MaybeT IO FilePath #

The directory for this version of ghc in the user's app directory (typically something like ~.ghcx86_64-linux-7.6.3)

settings :: DynFlags -> Settings #

"unbuild" a Settings from a DynFlags. This shouldn't be needed in the vast majority of code. But GHCi questionably uses this to produce a default DynFlags from which to compute a flags diff for printing.

flattenIncludes :: IncludeSpecs -> [String] #

Concatenate and flatten the list of global and quoted includes returning just a flat list of paths.

addQuoteInclude :: IncludeSpecs -> [String] -> IncludeSpecs #

Append to the list of includes a path that shall be included using `-iquote` when the C compiler is called. These paths only apply when quoted includes are used. e.g. #include "foo.h"

addGlobalInclude :: IncludeSpecs -> [String] -> IncludeSpecs #

Append to the list of includes a path that shall be included using `-I` when the C compiler is called. These paths override system search paths.

data WarnReason #

Used when outputting warnings: if a reason is given, it is displayed. If a warning isn't controlled by a flag, this is made explicit at the point of use.

Constructors

NoReason 
Reason !WarningFlag

Warning was enabled with the flag

ErrReason !(Maybe WarningFlag)

Warning was made an error because of -Werror or -Werror=WarningFlag

mainUnitId :: UnitId #

This is the package Id for the current program. It is the default package Id if you don't specify a package name. We don't add this prefix to symbol names, since there can be only one main package per program.

splitModuleInsts :: Module -> (InstalledModule, Maybe IndefModule) #

Given a possibly on-the-fly instantiated module, split it into a Module that we definitely can find on-disk, as well as an instantiation if we need to instantiate it on the fly. If the instantiation is Nothing no on-the-fly renaming is needed.

renameHoleUnitId' :: PackageConfigMap -> ShHoleSubst -> UnitId -> UnitId #

Like 'renameHoleUnitId, but requires only PackageConfigMap so it can be used by Packages.

renameHoleModule' :: PackageConfigMap -> ShHoleSubst -> Module -> Module #

Like renameHoleModule, but requires only PackageConfigMap so it can be used by Packages.

renameHoleUnitId :: DynFlags -> ShHoleSubst -> UnitId -> UnitId #

Substitutes holes in a UnitId, suitable for renaming when an include occurs; see Note [Representation of module/name variable].

p[A=A] maps to p[A=B] with A=B.

renameHoleModule :: DynFlags -> ShHoleSubst -> Module -> Module #

Substitutes holes in a Module. NOT suitable for being called directly on a nameModule, see Note [Representation of module/name variable]. p[A=A]:B maps to p[A=q():A]:B with A=q():A; similarly, A maps to q():A.

fsToUnitId :: FastString -> UnitId #

Create a new simple unit identifier from a FastString. Internally, this is primarily used to specify wired-in unit identifiers.

newSimpleUnitId :: ComponentId -> UnitId #

Create a new simple unit identifier (no holes) from a ComponentId.

stableUnitIdCmp :: UnitId -> UnitId -> Ordering #

Compares package ids lexically, rather than by their Uniques

newUnitId :: ComponentId -> [(ModuleName, Module)] -> UnitId #

Create a new, un-hashed unit identifier.

hashUnitId :: ComponentId -> [(ModuleName, Module)] -> FastString #

Generate a uniquely identifying FastString for a unit identifier. This is a one-way function. You can rely on one special property: if a unit identifier is in most general form, its FastString coincides with its ComponentId. This hash is completely internal to GHC and is not used for symbol names or file paths.

unitIdIsDefinite :: UnitId -> Bool #

A UnitId is definite if it has no free holes.

unitIdFreeHoles :: UnitId -> UniqDSet ModuleName #

Retrieve the set of free holes of a UnitId.

installedUnitIdEq :: InstalledUnitId -> UnitId -> Bool #

Test if a UnitId corresponds to a given InstalledUnitId, modulo instantiation.

installedModuleEq :: InstalledModule -> Module -> Bool #

Test if a Module corresponds to a given InstalledModule, modulo instantiation.

toInstalledUnitId :: UnitId -> InstalledUnitId #

Lossy conversion to the on-disk InstalledUnitId for a component.

indefUnitIdToUnitId :: DynFlags -> IndefUnitId -> UnitId #

Injects an IndefUnitId (indefinite library which was on-the-fly instantiated) to a UnitId (either an indefinite or definite library).

newIndefUnitId :: ComponentId -> [(ModuleName, Module)] -> IndefUnitId #

Create a new IndefUnitId given an explicit module substitution.

stableModuleCmp :: Module -> Module -> Ordering #

This gives a stable ordering, as opposed to the Ord instance which gives an ordering based on the Uniques of the components, which may not be stable from run to run of the compiler.

mkHoleModule :: ModuleName -> Module #

Create a module variable at some ModuleName. See Note [Representation of module/name variables]

moduleIsDefinite :: Module -> Bool #

A Module is definite if it has no free holes.

moduleFreeHoles :: Module -> UniqDSet ModuleName #

Calculate the free holes of a Module. If this set is non-empty, this module was defined in an indefinite library that had required signatures.

If a module has free holes, that means that substitutions can operate on it; if it has no free holes, substituting over a module has no effect.

moduleNameColons :: ModuleName -> String #

Returns the string version of the module name, with dots replaced by colons.

moduleNameSlashes :: ModuleName -> String #

Returns the string version of the module name, with dots replaced by slashes.

moduleStableString :: Module -> String #

Get a string representation of a Module that's unique and stable across recompilations. eg. "$aeson_70dylHtv1FFGeai1IoxcQr$Data.Aeson.Types.Internal"

stableModuleNameCmp :: ModuleName -> ModuleName -> Ordering #

Compares module names lexically, rather than by their Uniques

addBootSuffixLocnOut :: ModLocation -> ModLocation #

Add the -boot suffix to all output file paths associated with the module, not including the input file itself

addBootSuffixLocn :: ModLocation -> ModLocation #

Add the -boot suffix to all file paths associated with the module

addBootSuffix_maybe :: Bool -> FilePath -> FilePath #

Add the -boot suffix if the Bool argument is True

addBootSuffix :: FilePath -> FilePath #

Add the -boot suffix to .hs, .hi and .o files

data ModLocation #

Module Location

data IndefUnitId #

A unit identifier which identifies an indefinite library (with holes) that has been *on-the-fly* instantiated with a substitution indefUnitIdInsts. In fact, an indefinite unit identifier could have no holes, but we haven't gotten around to compiling the actual library yet.

An indefinite unit identifier pretty-prints to something like p[H=H,A=aimpl:A>] (p is the ComponentId, and the brackets enclose the module substitution).

data OverlapMode #

Constructors

NoOverlap SourceText

This instance must not overlap another NoOverlap instance. However, it may be overlapped by Overlapping instances, and it may overlap Overlappable instances.

Overlappable SourceText

Silently ignore this instance if you find a more specific one that matches the constraint you are trying to resolve

Example: constraint (Foo [Int]) instance Foo [Int] instance {--} Foo [a]

Since the second instance has the Overlappable flag, the first instance will be chosen (otherwise its ambiguous which to choose)

Overlapping SourceText

Silently ignore any more general instances that may be used to solve the constraint.

Example: constraint (Foo [Int]) instance {--} Foo [Int] instance Foo [a]

Since the first instance has the Overlapping flag, the second---more general---instance will be ignored (otherwise it is ambiguous which to choose)

Overlaps SourceText

Equivalent to having both Overlapping and Overlappable flags.

Incoherent SourceText

Behave like Overlappable and Overlapping, and in addition pick an an arbitrary one if there are multiple matching candidates, and don't worry about later instantiation

Example: constraint (Foo [b]) instance {-# INCOHERENT -} Foo [Int] instance Foo [a] Without the Incoherent flag, we'd complain that instantiating b would change which instance was chosen. See also note [Incoherent instances] in InstEnv

data FractionalLit #

Fractional Literal

Used (instead of Rational) to represent exactly the floating point literal that we encountered in the user's source program. This allows us to pretty-print exactly what the user wrote, which is important e.g. for floating point numbers that can't represented as Doubles (we used to via Double for pretty-printing). See also #2245.

data RealSrcSpan #

A RealSrcSpan delimits a portion of a text file. It could be represented by a pair of (line,column) coordinates, but in fact we optimise slightly by using more compact representations for single-line and zero-length spans, both of which are quite common.

The end position is defined to be the column after the end of the span. That is, a span of (1,1)-(1,2) is one character long, and a span of (1,1)-(1,1) is zero characters long.

data PrintUnqualified #

When printing code that contains original names, we need to map the original names back to something the user understands. This is the purpose of the triple of functions that gets passed around when rendering SDoc.

type QueryQualifyName = Module -> OccName -> QualifyName #

Given a Name's Module and OccName, decide whether and how to qualify it.

type QueryQualifyModule = Module -> Bool #

For a given module, we need to know whether to print it with a package name to disambiguate it.

type QueryQualifyPackage = UnitId -> Bool #

For a given package, we need to know whether to print it with the component id to disambiguate it.

data Module #

A Module is a pair of a UnitId and a ModuleName.

Module variables (i.e. H) which can be instantiated to a specific module at some later point in time are represented with moduleUnitId set to holeUnitId (this allows us to avoid having to make moduleUnitId a partial operation.)

data UnitId #

A unit identifier identifies a (possibly partially) instantiated library. It is primarily used as part of Module, which in turn is used in Name, which is used to give names to entities when typechecking.

There are two possible forms for a UnitId. It can be a DefiniteUnitId, in which case we just have a string that uniquely identifies some fully compiled, installed library we have on disk. However, when we are typechecking a library with missing holes, we may need to instantiate a library on the fly (in which case we don't have any on-disk representation.) In that case, you have an IndefiniteUnitId, which explicitly records the instantiation, so that we can substitute over it.

newtype InstalledUnitId #

An installed unit identifier identifies a library which has been installed to the package database. These strings are provided to us via the -this-unit-id flag. The library in question may be definite or indefinite; if it is indefinite, none of the holes have been filled (we never install partially instantiated libraries.) Put another way, an installed unit id is either fully instantiated, or not instantiated at all.

Installed unit identifiers look something like p+af23SAj2dZ219, or maybe just p if they don't use Backpack.

newtype ComponentId #

A ComponentId consists of the package name, package version, component ID, the transitive dependencies of the component, and other information to uniquely identify the source code and build configuration of a component.

This used to be known as an InstalledPackageId, but a package can contain multiple components and a ComponentId uniquely identifies a component within a package. When a package only has one component, the ComponentId coincides with the InstalledPackageId

Creates a FastString from a UTF-8 encoded [Word8]

mkFastString :: String -> FastString #

Creates a UTF-8 encoded FastString from a String

mkFastStringByteString :: ByteString -> FastString #

Create a FastString from an existing ForeignPtr; the difference between this and mkFastStringBytes is that we don't have to copy the bytes if the string is new to the table.

mkFastStringForeignPtr :: Ptr Word8 -> ForeignPtr Word8 -> Int -> IO FastString #

Create a FastString from an existing ForeignPtr; the difference between this and mkFastStringBytes is that we don't have to copy the bytes if the string is new to the table.

bytesFS :: FastString -> ByteString #

Gives the UTF-8 encoded bytes corresponding to a FastString

rnf :: FastZString -> () #

data FastString #

A FastString is a UTF-8 encoded string together with a unique ID. All FastStrings are stored in a global hashtable to support fast O(1) comparison.

It is also associated with a lazy reference to the Z-encoding of this string which is used by the compiler internally.

data Option #

When invoking external tools as part of the compilation pipeline, we pass these a sequence of options on the command-line. Rather than just using a list of Strings, we use a type that allows us to distinguish between filepaths and 'other stuff'. The reason for this is that this type gives us a handle on transforming filenames, and filenames only, to whatever format they're expected to be on a particular platform.
