Synopsis

Initialisation

defaultErrorHandler :: ExceptionMonad m => FatalMessager -> FlushOut -> m a -> m a Source #

Install some default exception handlers and run the inner computation. Unless you want to handle exceptions yourself, you should wrap this around the top level of your program. The default handlers output the error message(s) to stderr and exit cleanly.

defaultCleanupHandler :: ExceptionMonad m => DynFlags -> m a -> m a Source #

Deprecated: Cleanup is now done by runGhc/runGhcT

This function is no longer necessary, cleanup is now done by runGhc/runGhcT.

withSignalHandlers :: ExceptionMonad m => m a -> m a Source #

Temporarily install standard signal handlers for catching ^C, which just throw an exception in the current thread.

withCleanupSession :: GhcMonad m => m a -> m a Source #

GHC Monad

data Ghc a Source #

A minimal implementation of a GhcMonad. If you need a custom monad, e.g., to maintain additional state consider wrapping this monad or using GhcT.

class (Functor m, ExceptionMonad m, HasDynFlags m, HasLogger m) => GhcMonad m where Source #

A monad that has all the features needed by GHC API calls.

In short, a GHC monad

  • allows embedding of IO actions,
  • can log warnings,
  • allows handling of (extensible) exceptions, and
  • maintains a current session.

If you do not use Ghc or GhcT, make sure to call initGhcMonad before any call to the GHC API functions can occur.

data HscEnv Source #

HscEnv is like Session, except that some of the fields are immutable. An HscEnv is used to compile a single module from plain Haskell source code (after preprocessing) to either C, assembly or C--. It's also used to store the dynamic linker state to allow for multiple linkers in the same address space. Things like the module graph don't change during a single compilation.

Historical note: "hsc" used to be the name of the compiler binary, when there was a separate driver and compiler. To compile a single module, the driver would invoke hsc on the source code... so nowadays we think of hsc as the layer of the compiler that deals with compiling a single module.

runGhc Source #

Arguments

:: Maybe FilePath

See argument to initGhcMonad.

-> Ghc a

The action to perform.

-> IO a 

Run function for the Ghc monad.

It initialises the GHC session and warnings via initGhcMonad. Each call to this function will create a new session which should not be shared among several threads.

Any errors not handled inside the Ghc action are propagated as IO exceptions.

runGhcT Source #

Arguments

:: ExceptionMonad m 
=> Maybe FilePath

See argument to initGhcMonad.

-> GhcT m a

The action to perform.

-> m a 

Run function for GhcT monad transformer.

It initialises the GHC session and warnings via initGhcMonad. Each call to this function will create a new session which should not be shared among several threads.

initGhcMonad :: GhcMonad m => Maybe FilePath -> m () Source #

Initialise a GHC session.

If you implement a custom GhcMonad you must call this function in the monad run function. It will initialise the session variable and clear all warnings.

The first argument should point to the directory where GHC's library files reside. More precisely, this should be the output of ghc --print-libdir of the version of GHC the module using this API is compiled with. For portability, you should use the ghc-paths package, available at http://hackage.haskell.org/package/ghc-paths.

printException :: GhcMonad m => SourceError -> m () Source #

Print the error message and all warnings. Useful inside exception handlers. Clears warnings after printing.

handleSourceError Source #

Arguments

:: MonadCatch m 
=> (SourceError -> m a)

exception handler

-> m a

action to perform

-> m a 

Perform the given action and call the exception handler if the action throws a SourceError. See SourceError for more information.

needsTemplateHaskellOrQQ :: ModuleGraph -> Bool Source #

Determines whether a set of modules requires Template Haskell or Quasi Quotes

Note that if the session's DynFlags enabled Template Haskell when depanal was called, then each module in the returned module graph will have Template Haskell enabled whether it is actually needed or not.

data Backend Source #

Code generation backends.

GHC supports several code generation backends serving different purposes (producing machine code, producing ByteCode for the interpreter) and supporting different platforms.

Constructors

NCG

Native code generator backend.

Compiles Cmm code into textual assembler, then relies on an external assembler toolchain to produce machine code.

Only supports a few platforms (X86, PowerPC, SPARC).

See GHC.CmmToAsm.

LLVM

LLVM backend.

Compiles Cmm code into LLVM textual IR, then relies on LLVM toolchain to produce machine code.

It relies on LLVM support for the calling convention used by the NCG backend to produce code objects ABI compatible with it (see "cc 10" or "ghccc" calling convention in https://llvm.org/docs/LangRef.html#calling-conventions).

Support a few platforms (X86, AArch64, s390x, ARM).

See GHC.CmmToLlvm

ViaC

Via-C backend.

Compiles Cmm code into C code, then relies on a C compiler to produce machine code.

It produces code objects that are *not* ABI compatible with those produced by NCG and LLVM backends.

Produced code is expected to be less efficient than the one produced by NCG and LLVM backends because STG registers are not pinned into real registers. On the other hand, it supports more target platforms (those having a valid C toolchain).

See GHC.CmmToC

Interpreter

ByteCode interpreter.

Produce ByteCode objects (BCO, see GHC.ByteCode) that can be interpreted. It is used by GHCi.

Currently some extensions are not supported (foreign primops).

See GHC.StgToByteCode

NoBackend

No code generated.

Use this to disable code generation. It is particularly useful when GHC is used as a library for other purpose than generating code (e.g. to generate documentation with Haddock) or when the user requested it (via -fno-code) for some reason.

Note that dynamicNow (i.e., dynamic objects built with `-dynamic-too`) always implicitly enables Opt_PIC, Opt_ExternalDynamicRefs, and disables Opt_SplitSections.

data GhcMode Source #

The GhcMode tells us whether we're doing multi-module compilation (controlled via the GHC API) or one-shot (single-module) compilation. This makes a difference primarily to the GHC.Unit.Finder: in one-shot mode we look for interface files for imported modules, but in multi-module mode we look for source files in order to check whether they need to be recompiled.

Instances

parseTargetFiles :: DynFlags -> [String] -> (DynFlags, [(String, Maybe Phase)], [String]) Source #

Parse command line arguments that look like files. First normalises its arguments and then splits them into source files and object files. A source file can be turned into a Target via guessTarget

getSessionDynFlags :: GhcMonad m => m DynFlags Source #

Grabs the DynFlags from the Session

setSessionDynFlags :: GhcMonad m => DynFlags -> m () Source #

Updates both the interactive and program DynFlags in a Session. This also reads the package database (unless it has already been read), and prepares the compilers knowledge about packages. It can be called again to load new packages: just add new package flags to (packageFlags dflags).

getProgramDynFlags :: GhcMonad m => m DynFlags Source #

Returns the program DynFlags.

setProgramDynFlags :: GhcMonad m => DynFlags -> m Bool Source #

Sets the program DynFlags. Note: this invalidates the internal cached module graph, causing more work to be done the next time load is called.

Returns a boolean indicating if preload units have changed and need to be reloaded.

getInteractiveDynFlags :: GhcMonad m => m DynFlags Source #

Get the DynFlags used to evaluate interactive expressions.

setInteractiveDynFlags :: GhcMonad m => DynFlags -> m () Source #

Set the DynFlags used to evaluate interactive expressions. Also initialise (load) plugins.

Note: this cannot be used for changes to packages. Use setSessionDynFlags, or setProgramDynFlags and then copy the unitState into the interactive DynFlags.

interpretPackageEnv :: Logger -> DynFlags -> IO DynFlags Source #

Find the package environment (if one exists)

We interpret the package environment as a set of package flags; to be specific, if we find a package environment file like

clear-package-db
global-package-db
package-db blah/package.conf.d
package-id id1
package-id id2

we interpret this as

[ -hide-all-packages
, -clear-package-db
, -global-package-db
, -package-db blah/package.conf.d
, -package-id id1
, -package-id id2
]

There's also an older syntax alias for package-id, which is just an unadorned package id

id1
id2

Targets

data Target Source #

A compilation target.

A target may be supplied with the actual text of the module. If so, use this instead of the file contents (this is for use in an IDE where the file hasn't been saved by the user yet).

Constructors

Target 

Fields

  • targetId :: !TargetId

    module or filename

  • targetAllowObjCode :: !Bool

    object code allowed?

  • targetContents :: !(Maybe (InputFileBuffer, UTCTime))

    Optional in-memory buffer containing the source code GHC should use for this target instead of reading it from disk.

    Since GHC version 8.10 modules which require preprocessors such as Literate Haskell or CPP to run are also supported.

    If a corresponding source file does not exist on disk this will result in a SourceError exception if targetId = TargetModule _ is used. However together with targetId = TargetFile _ GHC will not complain about the file missing.

setTargets :: GhcMonad m => [Target] -> m () Source #

Sets the targets for this session. Each target may be a module name or a filename. The targets correspond to the set of root modules for the program/library. Unloading the current program is achieved by setting the current set of targets to be empty, followed by load.

getTargets :: GhcMonad m => m [Target] Source #

Returns the current set of targets

addTarget :: GhcMonad m => Target -> m () Source #

Add another target.

removeTarget :: GhcMonad m => TargetId -> m () Source #

Remove a target

guessTarget :: GhcMonad m => String -> Maybe Phase -> m Target Source #

Attempts to guess what Target a string refers to. This function implements the --make/GHCi command-line syntax for filenames:

  • if the string looks like a Haskell source filename, then interpret it as such
  • if adding a .hs or .lhs suffix yields the name of an existing file, then use that
  • otherwise interpret the string as a module name

Loading/compiling the program

depanal Source #

Arguments

:: GhcMonad m 
=> [ModuleName]

excluded modules

-> Bool

allow duplicate roots

-> m ModuleGraph 

Perform a dependency analysis starting from the current targets and update the session with the new module graph.

Dependency analysis entails parsing the import directives and may therefore require running certain preprocessors.

Note that each ModSummary in the module graph caches its DynFlags. These DynFlags are determined by the current session DynFlags and the OPTIONS and LANGUAGE pragmas of the parsed module. Thus if you want changes to the DynFlags to take effect you need to call this function again. In case of errors, just throw them.

depanalE Source #

Arguments

:: GhcMonad m 
=> [ModuleName]

excluded modules

-> Bool

allow duplicate roots

-> m (ErrorMessages, ModuleGraph) 

Perform dependency analysis like in depanal. In case of errors, the errors and an empty module graph are returned.

load :: GhcMonad m => LoadHowMuch -> m SuccessFlag Source #

Try to load the program. See LoadHowMuch for the different modes.

This function implements the core of GHC's --make mode. It preprocesses, compiles and loads the specified modules, avoiding re-compilation wherever possible. Depending on the backend (see backend field) compiling and loading may result in files being created on disk.

Calls the defaultWarnErrLogger after each compiling each module, whether successful or not.

If errors are encountered during dependency analysis, the module depanalE returns together with the errors an empty ModuleGraph. After processing this empty ModuleGraph, the errors of depanalE are thrown. All other errors are reported using the defaultWarnErrLogger.

data LoadHowMuch Source #

Describes which modules of the module graph need to be loaded.

Constructors

LoadAllTargets

Load all targets and its dependencies.

LoadUpTo ModuleName

Load only the given module and its dependencies.

LoadDependenciesOf ModuleName

Load only the dependencies of the given module, but not the module itself.

data InteractiveImport Source #

Constructors

IIDecl (ImportDecl GhcPs)

Bring the exports of a particular module (filtered by an import decl) into scope

IIModule ModuleName

Bring into scope the entire top-level envt of of this module, including the things imported into it.

ppr :: SuccessFlag -> SDoc Source #

type WarnErrLogger = forall m. GhcMonad m => Maybe SourceError -> m () Source #

A function called to log warnings and errors.

workingDirectoryChanged :: GhcMonad m => m () Source #

Inform GHC that the working directory has changed. GHC will flush its cache of module locations, since it may no longer be valid.

Note: Before changing the working directory make sure all threads running in the same session have stopped. If you change the working directory, you should also unload the current program (set targets to empty, followed by load).

parseModule :: GhcMonad m => ModSummary -> m ParsedModule Source #

Parse a module.

Throws a SourceError on parse error.

typecheckModule :: GhcMonad m => ParsedModule -> m TypecheckedModule Source #

Typecheck and rename a parsed module.

Throws a SourceError if either fails.

desugarModule :: GhcMonad m => TypecheckedModule -> m DesugaredModule Source #

Desugar a typechecked module.

loadModule :: (TypecheckedMod mod, GhcMonad m) => mod -> m mod Source #

Load a module. Input doesn't need to be desugared.

A module must be loaded before dependent modules can be typechecked. This always includes generating a ModIface_ and, depending on the DynFlags's backend, may also include code generation.

This function will always cause recompilation and will always overwrite previous compilation results (potentially files on disk).

data ParsedModule Source #

The result of successful parsing.

ppr :: CoreModule -> SDoc Source #

compileToCoreModule :: GhcMonad m => FilePath -> m CoreModule Source #

This is the way to get access to the Core bindings corresponding to a module. compileToCore parses, typechecks, and desugars the module, then returns the resulting Core module (consisting of the module name, type declarations, and function declarations) if successful.

compileToCoreSimplified :: GhcMonad m => FilePath -> m CoreModule Source #

Like compileToCoreModule, but invokes the simplifier, so as to return simplified and tidied Core.

Inspecting the module structure of the program

data ModuleGraph Source #

A 'ModuleGraph' contains all the nodes from the home package (only). See 'ModuleGraphNode' for information about the nodes.

Modules need to be compiled. hs-boots need to be typechecked before the associated "real" module so modules with {-# SOURCE #-} imports can be built. Instantiations also need to be typechecked to ensure that the module fits the signature. Substantiation typechecking is roughly comparable to the check that the module and its hs-boot agree.

The graph is not necessarily stored in topologically-sorted order. Use topSortModuleGraph and flattenSCC to achieve this.

mapMG :: (ModSummary -> ModSummary) -> ModuleGraph -> ModuleGraph Source #

Map a function f over all the ModSummaries. To preserve invariants f can't change the isBoot status.

mgLookupModule :: ModuleGraph -> Module -> Maybe ModSummary Source #

Look up a ModSummary in the ModuleGraph

data ModSummary Source #

Data for a module node in a ModuleGraph. Module nodes of the module graph are one of:

  • A regular Haskell source module
  • A hi-boot source module

ppr :: ModSummary -> SDoc Source #

data ModLocation Source #

Module Location

Where a module lives on the file system: the actual locations of the .hs, .hi and .o files, if we have them.

For a module in another unit, the ml_hs_file and ml_obj_file components of ModLocation are undefined.

The locations specified by a ModLocation may or may not correspond to actual files yet: for example, even if the object file doesn't exist, the ModLocation still contains the path to where the object file will reside if/when it is created.

Constructors

ModLocation 

Fields

  • ml_hs_file :: Maybe FilePath

    The source file, if we have one. Package modules probably don't have source files.

  • ml_hi_file :: FilePath

    Where the .hi file is, whether or not it exists yet. Always of form foo.hi, even if there is an hi-boot file (we add the -boot suffix later)

  • ml_obj_file :: FilePath

    Where the .o file is, whether or not it exists yet. (might not exist either because the module hasn't been compiled yet, or because it is part of a unit with a .a file)

  • ml_hie_file :: FilePath

    Where the .hie file is, whether or not it exists yet.

getModSummary :: GhcMonad m => ModuleName -> m ModSummary Source #

Return the ModSummary of a module with the given name.

The module must be part of the module graph (see hsc_mod_graph and ModuleGraph). If this is not the case, this function will throw a GhcApiError.

This function ignores boot modules and requires that there is only one non-boot module with the given name.

getModuleGraph :: GhcMonad m => m ModuleGraph Source #

Get the module dependency graph.

isLoaded :: GhcMonad m => ModuleName -> m Bool Source #

Return True <==> module is loaded.

topSortModuleGraph Source #

Arguments

:: Bool

Drop hi-boot nodes? (see below)

-> ModuleGraph 
-> Maybe ModuleName

Root module name. If Nothing, use the full graph.

-> [SCC ModuleGraphNode] 

Topological sort of the module graph

Calculate SCCs of the module graph, possibly dropping the hi-boot nodes The resulting list of strongly-connected-components is in topologically sorted order, starting with the module(s) at the bottom of the dependency graph (ie compile them first) and ending with the ones at the top.

Drop hi-boot nodes (first boolean arg)?

  • False: treat the hi-boot summaries as nodes of the graph, so the graph must be acyclic
  • True: eliminate the hi-boot nodes, and instead pretend the a source-import of Foo is an import of Foo The resulting graph has no hi-boot nodes, but can be cyclic

Inspecting modules

data ModuleInfo Source #

Container for information about a Module.

getModuleInfo :: GhcMonad m => Module -> m (Maybe ModuleInfo) Source #

Request information about a loaded Module

modInfoTyThings :: ModuleInfo -> [TyThing] Source #

modInfoInstances :: ModuleInfo -> [ClsInst] Source #

Returns the instances defined by the specified module. Warning: currently unimplemented for package modules.

modInfoSafe :: ModuleInfo -> SafeHaskellMode Source #

Retrieve module safe haskell mode

lookupGlobalName :: GhcMonad m => Name -> m (Maybe TyThing) Source #

Looks up a global name: that is, any top-level name in any visible module. Unlike lookupName, lookupGlobalName does not use the interactive context, and therefore does not require a preceding setContext.

findGlobalAnns :: (GhcMonad m, Typeable a) => ([Word8] -> a) -> AnnTarget Name -> m [a] Source #

type ModIface = ModIface_ 'ModIfaceFinal Source #

data ModIface_ (phase :: ModIfacePhase) Source #

A ModIface_ plus a ModDetails summarises everything we know about a compiled module. The ModIface_ is the stuff *before* linking, and can be written out to an interface file. The 'ModDetails is after linking and can be completely recovered from just the ModIface_.

When we read an interface file, we also construct a ModIface_ from it, except that we explicitly make the mi_decls and a few other fields empty; as when reading we consolidate the declarations etc. into a number of indexed maps and environments in the ExternalPackageState.

Constructors

ModIface 

Fields

  • mi_module :: !Module

    Name of the module we are for

  • mi_sig_of :: !(Maybe Module)

    Are we a sig of another mod?

  • mi_hsc_src :: !HscSource

    Boot? Signature?

  • mi_deps :: Dependencies

    The dependencies of the module. This is consulted for directly-imported modules, but not for anything else (hence lazy)

  • mi_usages :: [Usage]

    Usages; kept sorted so that it's easy to decide whether to write a new iface file (changing usages doesn't affect the hash of this module) NOT STRICT! we read this field lazily from the interface file It is *only* consulted by the recompilation checker

  • mi_exports :: ![IfaceExport]

    Exports Kept sorted by (mod,occ), to make version comparisons easier Records the modules that are the declaration points for things exported by this module, and the OccNames of those things

  • mi_used_th :: !Bool

    Module required TH splices when it was compiled. This disables recompilation avoidance (see #481).

  • mi_fixities :: [(OccName, Fixity)]

    Fixities NOT STRICT! we read this field lazily from the interface file

  • mi_warns :: Warnings

    Warnings NOT STRICT! we read this field lazily from the interface file

  • mi_anns :: [IfaceAnnotation]

    Annotations NOT STRICT! we read this field lazily from the interface file

  • mi_decls :: [IfaceDeclExts phase]

    Type, class and variable declarations The hash of an Id changes if its fixity or deprecations change (as well as its type of course) Ditto data constructors, class operations, except that the hash of the parent class/tycon changes

  • mi_globals :: !(Maybe GlobalRdrEnv)

    Binds all the things defined at the top level in the original source code for this module. which is NOT the same as mi_exports, nor mi_decls (which may contains declarations for things not actually defined by the user). Used for GHCi and for inspecting the contents of modules via the GHC API only.

    (We need the source file to figure out the top-level environment, if we didn't compile this module from source then this field contains Nothing).

    Strictly speaking this field should live in the HomeModInfo, but that leads to more plumbing.

  • mi_insts :: [IfaceClsInst]

    Sorted class instance

  • mi_fam_insts :: [IfaceFamInst]

    Sorted family instances

  • mi_rules :: [IfaceRule]

    Sorted rules

  • mi_hpc :: !AnyHpcUsage

    True if this program uses Hpc at any point in the program.

  • mi_trust :: !IfaceTrustInfo

    Safe Haskell Trust information for this module.

  • mi_trust_pkg :: !Bool

    Do we require the package this module resides in be trusted to trust this module? This is used for the situation where a module is Safe (so doesn't require the package be trusted itself) but imports some trustworthy modules from its own package (which does require its own package be trusted). See Note [Trust Own Package] in GHC.Rename.Names

  • mi_complete_matches :: [IfaceCompleteMatch]
     
  • mi_doc_hdr :: Maybe HsDocString

    Module header.

  • mi_decl_docs :: DeclDocMap

    Docs on declarations.

  • mi_arg_docs :: ArgDocMap

    Docs on arguments.

  • mi_final_exts :: !(IfaceBackendExts phase)

    Either () or ModIfaceBackend for a fully instantiated interface.

  • mi_ext_fields :: ExtensibleFields

    Additional optional fields, where the Map key represents the field name, resulting in a (size, serialized data) pair. Because the data is intended to be serialized through the internal Binary class (increasing compatibility with types using Name and FastString, such as HIE), this format is chosen over ByteStrings.

Executing statements

execStmt Source #

Arguments

:: GhcMonad m 
=> String

a statement (bind or expression)

-> ExecOptions 
-> m ExecResult 

Run a statement in the current interactive context.

execStmt' :: GhcMonad m => GhciLStmt GhcPs -> String -> ExecOptions -> m ExecResult Source #

Like execStmt, but takes a parsed statement as argument. Useful when doing preprocessing on the AST before execution, e.g. in GHCi (see GHCi.UI.runStmt).

data ExecOptions Source #

Constructors

ExecOptions 

Fields

execOptions :: ExecOptions Source #

runDeclsWithLocation :: GhcMonad m => String -> Int -> String -> m [Name] Source #

Run some declarations and return any user-visible names that were brought into scope.

runParsedDecls :: GhcMonad m => [LHsDecl GhcPs] -> m [Name] Source #

Like runDeclsWithLocation, but takes parsed declarations as argument. Useful when doing preprocessing on the AST before execution, e.g. in GHCi (see GHCi.UI.runStmt).

Get/set the current context

setContext :: GhcMonad m => [InteractiveImport] -> m () Source #

Set the interactive evaluation context.

(setContext imports) sets the ic_imports field (which in turn determines what is in scope at the prompt) to imports, and constructs the ic_rn_glb_env environment to reflect it.

We retain in scope all the things defined at the prompt, and kept in ic_tythings. (Indeed, they shadow stuff from ic_imports.)

getContext :: GhcMonad m => m [InteractiveImport] Source #

Get the interactive evaluation context, consisting of a pair of the set of modules from which we take the full top-level scope, and the set of modules from which we take just the exports respectively.

setGHCiMonad :: GhcMonad m => String -> m () Source #

Set the monad GHCi lifts user statements into.

Checks that a type (in string form) is an instance of the GHC.GHCi.GHCiSandboxIO type class. Sets it to be the GHCi monad if it is, throws an error otherwise.

getGHCiMonad :: GhcMonad m => m Name Source #

Get the monad GHCi lifts user statements into.

Inspecting the current context

getBindings :: GhcMonad m => m [TyThing] Source #

Return the bindings for the current interactive session.

getInsts :: GhcMonad m => m ([ClsInst], [FamInst]) Source #

Return the instances for the current interactive session.

findModule :: GhcMonad m => ModuleName -> Maybe FastString -> m Module Source #

Takes a ModuleName and possibly a UnitId, and consults the filesystem and package database to find the corresponding Module, using the algorithm that is used for an import declaration.

lookupModule :: GhcMonad m => ModuleName -> Maybe FastString -> m Module Source #

Like findModule, but differs slightly when the module refers to a source file, and the file has not been loaded via load. In this case, findModule will throw an error (module not loaded), but lookupModule will check to see whether the module can also be found in a package, and if so, that package Module will be returned. If not, the usual module-not-found error will be thrown.

isModuleTrusted :: GhcMonad m => Module -> m Bool Source #

Check that a module is safe to import (according to Safe Haskell).

We return True to indicate the import is safe and False otherwise although in the False case an error may be thrown first.

moduleTrustReqs :: GhcMonad m => Module -> m (Bool, Set UnitId) Source #

Return if a module is trusted and the pkgs it depends on to be trusted.

getNamesInScope :: GhcMonad m => m [Name] Source #

Returns all names in scope in the current interactive context

getRdrNamesInScope :: GhcMonad m => m [RdrName] Source #

Returns all RdrNames in scope in the current interactive context, excluding any that are internally-generated.

getGRE :: GhcMonad m => m GlobalRdrEnv Source #

get the GlobalRdrEnv for a session

moduleIsInterpreted :: GhcMonad m => Module -> m Bool Source #

Returns True if the specified module is interpreted, and hence has its full top-level scope available.

getInfo :: GhcMonad m => Bool -> Name -> m (Maybe (TyThing, Fixity, [ClsInst], [FamInst], SDoc)) Source #

Looks up an identifier in the current interactive context (for :info) Filter the instances by the ones whose tycons (or clases resp) are in scope (qualified or otherwise). Otherwise we list a whole lot too many! The exact choice of which ones to show, and which to hide, is a judgement call. (see #1581)

getNameToInstancesIndex Source #

Arguments

:: GhcMonad m 
=> [Module]

visible modules. An orphan instance will be returned if it is visible from at least one module in the list.

-> Maybe [Module]

modules to load. If this is not specified, we load modules for everything that is in scope unqualified.

-> m (Messages DecoratedSDoc, Maybe (NameEnv ([ClsInst], [FamInst]))) 

Retrieve all type and family instances in the environment, indexed by Name. Each name's lists will contain every instance in which that name is mentioned in the instance head.

Identifiers

type Id = Var Source #

Identifier

isImplicitId :: Id -> Bool Source #

isImplicitId tells whether an Ids info is implied by other declarations, so we don't need to put its signature in an interface file, even if it's mentioned in some other interface unfolding.

isExportedId :: Var -> Bool Source #

isExportedIdVar means "don't throw this away"

idDataCon :: Id -> DataCon Source #

Get from either the worker or the wrapper Id to the DataCon. Currently used only in the desugarer.

INVARIANT: idDataCon (dataConWrapId d) = d: remember, dataConWrapId can return either the wrapper or the worker

isDeadEndId :: Var -> Bool Source #

Returns true if an application to n args diverges or throws an exception See Note [Dead ends] in GHC.Types.Demand.

recordSelectorTyCon :: Id -> RecSelParent Source #

If the Id is that for a record selector, extract the sel_tycon. Panic otherwise.

Type constructors

data TyCon Source #

TyCons represent type constructors. Type constructors are introduced by things such as:

1) Data declarations: data Foo = ... creates the Foo type constructor of kind *

2) Type synonyms: type Foo = ... creates the Foo type constructor

3) Newtypes: newtype Foo a = MkFoo ... creates the Foo type constructor of kind * -> *

4) Class declarations: class Foo where creates the Foo type constructor of kind *

This data type also encodes a number of primitive, built in type constructors such as those for function and tuple types.

type Kind = Type Source #

The key type representing kinds in the compiler.

type PredType = Type Source #

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"

data RealSrcSpan Source #

A SrcSpan 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.
