valuegetModuleGraph :: GhcMonad m => m ModuleGraph

Get the module dependency graph.

valueisLoaded :: GhcMonad m => ModuleName -> m Bool

Deprecated. Prefer isLoadedModule and isLoadedHomeModule

Return True <==> module is loaded.

valueisLoadedModule :: GhcMonad m => UnitId -> ModuleName -> m Bool

Check whether a ModuleName is found in the HomePackageTable for the given UnitId.

valueisLoadedHomeModule :: GhcMonad m => Module -> m Bool

Check whether Module is part of the HomeUnitGraph.

Similar to isLoadedModule, but for Modules.

valuegetBindings :: GhcMonad m => m [TyThing]

Return the bindings for the current interactive session.

valuegetInsts :: GhcMonad m => m ([ClsInst], [FamInst])

Return the instances for the current interactive session.

valuegetNamePprCtx :: GhcMonad m => m NamePprCtx

datadata ModuleInfo

Container for information about a Module.

valuegetModuleInfo :: GhcMonad m => Module -> m (Maybe ModuleInfo)

Request information about a loaded Module

valuegetPackageModuleInfo :: HscEnv -> Module -> IO (Maybe ModuleInfo)

valueavailsToGlobalRdrEnv

valuegetHomeModuleInfo :: HscEnv -> Module -> IO (Maybe ModuleInfo)

valuemodInfoTyThings :: ModuleInfo -> [TyThing]

The list of top-level entities defined in a module

valuemodInfoExports :: ModuleInfo -> [Name]

valuemodInfoExportsWithSelectors :: ModuleInfo -> [Name]

valuemodInfoInstances :: ModuleInfo -> [ClsInst]

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

valuemodInfoIsExportedName :: ModuleInfo -> Name -> Bool

valuemkNamePprCtxForModule :: GhcMonad m => Module -> ModuleInfo -> m NamePprCtx

valuemodInfoLookupName :: GhcMonad m => ModuleInfo -> Name -> m (Maybe TyThing)
