(c) Simon Marlow 2005 (c) Lemmih 2006
Synopsis
- getImports :: DynFlags -> StringBuffer -> FilePath -> FilePath -> IO (Either ErrorMessages ([(Maybe FastString, Located ModuleName)], [(Maybe FastString, Located ModuleName)], Located ModuleName))
- mkPrelImports :: ModuleName -> SrcSpan -> Bool -> [LImportDecl GhcPs] -> [LImportDecl GhcPs]
- getOptionsFromFile :: DynFlags -> FilePath -> IO [Located String]
- getOptions :: DynFlags -> StringBuffer -> FilePath -> [Located String]
- optionsErrorMsgs :: DynFlags -> [String] -> [Located String] -> FilePath -> Messages
- checkProcessArgsResult :: MonadIO m => DynFlags -> [Located String] -> m ()

Arguments
| :: DynFlags | |
| -> StringBuffer | Parse this. |
| -> FilePath | Filename the buffer came from. Used for reporting parse error locations. |
| -> FilePath | The original source filename (used for locations in the function result) |
| -> IO (Either ErrorMessages ([(Maybe FastString, Located ModuleName)], [(Maybe FastString, Located ModuleName)], Located ModuleName)) | The source imports and normal imports (with optional package names from -XPackageImports), and the module name. |
Parse the imports of a source file.
Throws a SourceError if parsing fails.
mkPrelImports :: ModuleName -> SrcSpan -> Bool -> [LImportDecl GhcPs] -> [LImportDecl GhcPs] Source #
Parse OPTIONS and LANGUAGE pragmas of the source file.
Throws a SourceError if flag parsing fails (including unsupported flags.)
Arguments
| :: DynFlags | |
| -> StringBuffer | Input Buffer |
| -> FilePath | Source filename. Used for location info. |
| -> [Located String] | Parsed options. |
Parse OPTIONS and LANGUAGE pragmas of the source file.
Throws a SourceError if flag parsing fails (including unsupported flags.)
checkProcessArgsResult :: MonadIO m => DynFlags -> [Located String] -> m () Source #
Complain about non-dynamic flags in OPTIONS pragmas.
Throws a SourceError if the input list is non-empty claiming that the
input flags are unknown.
