Parsing of Haskell source files

parseFile :: FilePath -> IO (ParseResult Module)

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

parseFileWithMode :: ParseMode -> FilePath -> IO (ParseResult Module)

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

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

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

parseFileWithComments :: ParseMode -> FilePath -> IO (ParseResult (Module, [Comment]))

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

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

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

parseFileContents :: String -> ParseResult Module

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

parseFileContentsWithMode :: ParseMode -> String -> ParseResult Module

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

parseFileContentsWithExts :: [Extension] -> String -> ParseResult Module

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

parseFileContentsWithComments :: ParseMode -> String -> ParseResult (Module, [Comment])

Parse a source file from a string using a custom parse mode and retaining comments.

parseFileContentsWithCommentsAndPragmas :: ParseMode -> String -> ParseResult (Module, [Comment], [UnknownPragma])

Parse a source file from a string using a custom parse mode retaining comments as well as unknown pragmas.

Read extensions declared in LANGUAGE pragmas

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

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