Documentation

flushFinderCaches :: HscEnv -> IO () Source #

data FindResult Source #

The result of searching for an imported module.

NB: FindResult manages both user source-import lookups (which can result in Module) as well as direct imports for interfaces (which always result in InstalledModule).

Constructors

Found ModLocation Module	The module was found
NoPackage UnitId	The requested package was not found
FoundMultiple [(Module, ModuleOrigin)]	_Error_: both in multiple packages
NotFound	Not found

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

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.

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

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.

findExactModule :: HscEnv -> InstalledModule -> IO InstalledFindResult Source #

Locate a specific Module. The purpose of this function is to create a ModLocation for a given Module, that is to find out where the files associated with this module live. It is used when reading the interface for a module mentioned by another interface, for example (a "system import").

findHomeModule :: HscEnv -> ModuleName -> IO FindResult Source #

findExposedPackageModule :: HscEnv -> ModuleName -> Maybe FastString -> IO FindResult Source #

mkHomeModLocation :: DynFlags -> ModuleName -> FilePath -> IO ModLocation Source #

mkHomeModLocation2 :: DynFlags -> ModuleName -> FilePath -> String -> IO ModLocation Source #

mkHiOnlyModLocation :: DynFlags -> Suffix -> FilePath -> String -> IO ModLocation Source #

mkHiPath :: DynFlags -> FilePath -> String -> FilePath Source #

Constructs the filename of a .hi file for a given source file. Does not check whether the .hi file exists

mkObjPath :: DynFlags -> FilePath -> String -> FilePath Source #

Constructs the filename of a .o file for a given source file. Does not check whether the .o file exists

addHomeModuleToFinder :: HscEnv -> ModuleName -> ModLocation -> IO Module Source #

uncacheModule :: HscEnv -> ModuleName -> IO () Source #

mkStubPaths :: DynFlags -> ModuleName -> ModLocation -> FilePath Source #

findObjectLinkableMaybe :: Module -> ModLocation -> IO (Maybe Linkable) Source #

findObjectLinkable :: Module -> FilePath -> UTCTime -> IO Linkable Source #

cannotFindModule :: DynFlags -> ModuleName -> FindResult -> SDoc Source #

cannotFindInterface :: DynFlags -> ModuleName -> InstalledFindResult -> SDoc Source #
