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 |
Fields

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 #
