lookupLocalOccThLvl_maybe :: Name -> RnM (Maybe (TopLevelFlag, ThLevel)) Source #
lookupOccRn_overloaded :: Bool -> RdrName -> RnM (Maybe (Either Name [FieldOcc Name])) Source #
Like lookupOccRn_maybe, but with a more informative result if
the RdrName happens to be a record selector:
- Nothing -> name not in scope (no error reported)
- Just (Left x) -> name uniquely refers to x, or there is a name clash (reported)
- Just (Right xs) -> name refers to one or more record selectors; if overload_ok was False, this list will be a singleton.
lookupGlobalOccRn_overloaded :: Bool -> RdrName -> RnM (Maybe (Either Name [FieldOcc Name])) Source #
unknownNameSuggestions :: DynFlags -> GlobalRdrEnv -> LocalRdrEnv -> ImportAvails -> RdrName -> SDoc Source #
Called from the typechecker (TcErrors) when we find an unbound variable
addNameClashErrRn :: RdrName -> [GlobalRdrElt] -> RnM () Source #
Arguments
| :: HsSigCtxt | |
| -> SDoc | description of thing we're looking up, like "type family" |
| -> Located RdrName | |
| -> RnM (Located Name) |
Lookup a name in relation to the names in a HsSigCtxt
lookupFixityRn_help :: Name -> RnM (Bool, Fixity) Source #
lookupFixityRn_help returns (True, fixity) if it finds a Fixity
in a local environment or from an interface file. Otherwise, it returns
(False, fixity) (e.g., for unbound Names or Names without
user-supplied fixity declarations).
lookupFieldFixityRn :: AmbiguousFieldOcc Name -> RnM Fixity Source #
Look up the fixity of a (possibly ambiguous) occurrence of a record field
selector. We use lookupFixityRn' so that we can specifiy the OccName as
the field label, which might be different to the OccName of the selector
Name if DuplicateRecordFields is in use (Trac #1173). If there are
multiple possible selectors with different fixities, generate an error.
