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

Constructors

Fields

- ms_mod :: Module

  Identity of the module

- ms_hsc_src :: HscSource

  The module source either plain Haskell, hs-boot, or hsig

- ms_location :: ModLocation

  Location of the various files belonging to the module

- ms_hs_hash :: Fingerprint

  Content hash of source file

- ms_obj_date :: Maybe UTCTime

  Timestamp of object, if we have one

- ms_dyn_obj_date :: !(Maybe UTCTime)

  Timestamp of dynamic object, if we have one

- ms_iface_date :: Maybe UTCTime

  Timestamp of hi file, if we have one See Note [When source is considered modified] and #9243

- ms_hie_date :: Maybe UTCTime

  Timestamp of hie file, if we have one

- ms_srcimps :: [(PkgQual, Located ModuleName)]

  Source imports of the module

- ms_textual_imps :: [(PkgQual, Located ModuleName)]

  Non-source imports of the module from the module *text*

- ms_ghc_prim_import :: !Bool

  Whether the special module GHC.Prim was imported explicitly

- ms_parsed_mod :: Maybe HsParsedModule

  The parsed, nonrenamed source, if we have it. This is also used to support "inline module syntax" in Backpack files.

- ms_hspp_file :: FilePath

  Filename of preprocessed source file

- ms_hspp_opts :: DynFlags

  Cached flags from `OPTIONS`, `INCLUDE` and `LANGUAGE` pragmas in the modules source code

- ms_hspp_buf :: Maybe StringBuffer

  The actual preprocessed source, if we have it

Instance details Defined in GHC.Unit.Module.ModSummary Methods ppr :: ModSummary -> SDoc Source #

ms_unitid :: ModSummary -> UnitId Source #

ms_installed_mod :: ModSummary -> InstalledModule Source #

ms_mod_name :: ModSummary -> ModuleName Source #

ms_imps :: ModSummary -> [(PkgQual, Located ModuleName)] Source #

Textual imports, plus plugin imports but not SOURCE imports.

ms_plugin_imps :: ModSummary -> [(PkgQual, Located ModuleName)] Source #

Plugin imports

ms_mnwib :: ModSummary -> ModuleNameWithIsBoot Source #

ms_home_srcimps :: ModSummary -> [Located ModuleName] Source #

Like `ms_home_imps`, but for SOURCE imports.

ms_home_imps :: ModSummary -> [(PkgQual, Located ModuleName)] Source #

All of the (possibly) home module imports from a `ModSummary`; that is to say, each of these module names could be a home import if an appropriately named file existed. (This is in contrast to package qualified imports, which are guaranteed not to be home imports.)

msHiFilePath :: ModSummary -> FilePath Source #

msDynHiFilePath :: ModSummary -> FilePath Source #

msHsFilePath :: ModSummary -> FilePath Source #

msObjFilePath :: ModSummary -> FilePath Source #

msDynObjFilePath :: ModSummary -> FilePath Source #

msDeps :: ModSummary -> [(PkgQual, GenWithIsBoot (Located ModuleName))] Source #

Returns the dependencies of the ModSummary s.

isBootSummary :: ModSummary -> IsBootInterface Source #

Did this `ModSummary` originate from a hs-boot file?

findTarget :: ModSummary -> [Target] -> Maybe Target Source #

Find the first target in the provided list which matches the specified `ModSummary`.
