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 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.

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

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

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

Parsing of Haskell source elements,

parseModule :: String -> ParseResult (Module SrcSpanInfo) Source

Parse of a string, which should contain a complete Haskell module.

Parse of a string containing a Haskell statement.

parseStmtWithMode :: ParseMode -> String -> ParseResult (Stmt SrcSpanInfo) Source

Parse of a string containing a Haskell type, using an explicit mode.

parseStmtWithComments :: ParseMode -> String -> ParseResult (Stmt SrcSpanInfo, [Comment]) Source

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.
