FinderCache
Fields fcModuleCache :: IORef FinderCacheState fcFileCache :: IORef FileCacheState

type FinderCacheState = InstalledModuleEnv InstalledFindResult Source #

The FinderCache maps modules to the result of searching for that module. It records the results of searching for modules along the search path. On :load, we flush the entire contents of this cache.

data FindResult Source #

The result of searching for an imported module.

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

Constructors

Found ModLocation Module	The module was found
NoPackage Unit	The requested unit was not found
FoundMultiple [(Module, ModuleOrigin)]	_Error_: both in multiple packages
NotFound	Not found
Fields fr_paths :: [FilePath] Places where I looked fr_pkg :: Maybe Unit Just p => module is in this unit's manifest, but couldn't find the .hi file fr_mods_hidden :: [Unit] Module is in these units, but the module is hidden fr_pkgs_hidden :: [Unit] Module is in these units, but the unit is hidden fr_unusables :: [(Unit, UnusableUnitReason)] Module is in these units, but it is unusable fr_suggestions :: [ModuleSuggestion] Possible mis-spelled modules

data InstalledFindResult Source #

Constructors

InstalledFound ModLocation InstalledModule
InstalledNoPackage UnitId
InstalledNotFound [FilePath] (Maybe UnitId)

data FinderOpts Source #

Locations and information the finder cares about.

Should be taken from DynFlags via initFinderOpts.

FinderOpts

Fields

finder_importPaths :: [FilePath]
Where are we allowed to look for Modules and Source files
finder_lookupHomeInterfaces :: Bool
When looking up a home module:
- True: search interface files (e.g. in '-c' mode)
- False: search source files (e.g. in '--make' mode)
finder_bypassHiFileCheck :: Bool
Don't check that an imported interface file actually exists if it can only be at one location. The interface will be reported as InstalledFound even if the file doesn't exist, so this is only useful in specific cases (e.g. to generate dependencies with `ghc -M`)
finder_ways :: Ways
finder_enableSuggestions :: Bool
If we encounter unknown modules, should we suggest modules that have a similar name.
finder_workingDirectory :: Maybe FilePath
finder_thisPackageName :: Maybe FastString
finder_hiddenModules :: Set ModuleName
finder_reexportedModules :: Set ModuleName
finder_hieDir :: Maybe FilePath
finder_hieSuf :: String
finder_hiDir :: Maybe FilePath
finder_hiSuf :: String
finder_dynHiSuf :: String
finder_objectDir :: Maybe FilePath
finder_objectSuf :: String
finder_dynObjectSuf :: String
finder_stubDir :: Maybe FilePath
