datadata HsModule p

Haskell Module

All we actually declare here is the top-level structure for a module.

Constructors

HsModule
- hsmodExt :: XCModule p
  HsModule extension point
- hsmodName :: Maybe (XRec p ModuleName)
  Nothing: "module X where" is omitted (in which case the next field is Nothing too)
- hsmodExports :: Maybe (XRec p [LIE p])
  Export list
  - Nothing: export list omitted, so export everything
  - Just []: export nothing
  - Just [...]: as you would expect...
- hsmodImports :: [LImportDecl p]
- hsmodDecls :: [LHsDecl p]
  Type, class, value, and interface signature decls
XModule !(XXModule p)

datadata AnnsModule

Constructors

AnnsModule
- am_sig :: EpToken "signature"
- am_mod :: EpToken "module"
- am_where :: EpToken "where"
- am_decls :: [TrailingAnn]
  Semis before the start of top decls
- am_cs :: [LEpaComment]
  Comments before start of top decl, used in exact printing only
- am_eof :: Maybe (RealSrcSpan, RealSrcSpan)
  End of file and end of prior token

datadata HsParsedModule

Constructors

HsParsedModule
- hpm_module :: Located (HsModule GhcPs)
- hpm_src_files :: [FilePath]
  extra source files (e.g. from #includes). The lexer collects these from '# file line' pragmas, which the C preprocessor leaves behind. These files and their timestamps are stored in the .hi file, so that we can force recompilation if any of them change (#3589)

datadata XModulePs

Haskell Module extension point: GHC specific

Constructors

XModulePs
- hsmodAnn :: EpAnn AnnsModule
- hsmodLayout :: EpLayout
  Layout info for the module. For incomplete modules (e.g. the output of parseHeader), it is EpNoLayout.
- hsmodDeprecMessage :: Maybe (LWarningTxt GhcPs)
  reason/explanation for warning/deprecation of this module
- hsmodHaddockModHeader :: Maybe (LHsDoc GhcPs)
  Haddock module info and description, unparsed
