Synopsis

Re-exported modules

Parsing of Haskell source files

parseFile :: FilePath -> IO (ParseResult (Module SrcSpanInfo)) Source #

Parse a source file on disk, using the default parse mode.

parseFileWithMode :: ParseMode -> FilePath -> IO (ParseResult (Module SrcSpanInfo)) Source #

Parse a source file on disk, supplying a custom parse mode.

parseFileWithExts :: [Extension] -> FilePath -> IO (ParseResult (Module SrcSpanInfo)) Source #

Parse a source file on disk, with an extra set of extensions to know about on top of what the file itself declares.

parseFileWithCommentsAndPragmas :: ParseMode -> FilePath -> IO (ParseResult (Module SrcSpanInfo, [Comment], [UnknownPragma])) Source #

Parse a source file on disk, supplying a custom parse mode, and retaining comments as well as unknown pragmas.

parseFileContents :: String -> ParseResult (Module SrcSpanInfo) Source #

Parse a source file from a string using the default parse mode.

parseFileContentsWithMode :: ParseMode -> String -> ParseResult (Module SrcSpanInfo) Source #

Parse a source file from a string using a custom parse mode.

parseFileContentsWithExts :: [Extension] -> String -> ParseResult (Module SrcSpanInfo) Source #

Parse a source file from a string, with an extra set of extensions to know about on top of what the file itself declares.

Read extensions declared in LANGUAGE pragmas

readExtensions :: String -> Maybe (Maybe Language, [Extension]) Source #

Gather the extensions declared in LANGUAGE pragmas at the top of the file. Returns Nothing if the parse of the pragmas fails.
