Description

An umbrella module for the various functionality of the package. Also provides some convenient functionality for dealing directly with source files.

Parsing of Haskell source files

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

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

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

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

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

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])) Source

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

parseFileContents :: String -> ParseResult Module Source

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

parseFileContentsWithMode :: ParseMode -> String -> ParseResult Module Source

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

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

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

Read extensions declared in LANGUAGE pragmas

readExtensions :: String -> Maybe [Extension] Source

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