Efficiency concerns rule out both lists and lazy --- bytestrings. The usual use for lazy bytestrings would be to --- allow consumption of very large input without a large footprint. --- For this need, attoparsec's incremental input provides an --- excellent substitute, with much more control over when input --- takes place. If you must use lazy bytestrings, see the --- "Data.Attoparsec.ByteString.Lazy" module, which feeds lazy chunks --- to a regular parser. --- --- * Parsec parsers can produce more helpful error messages than --- attoparsec parsers. This is a matter of focus: attoparsec avoids --- the extra book-keeping in favour of higher performance. - --- $incremental --- --- attoparsec supports incremental input, meaning that you can feed it --- a bytestring that represents only part of the expected total amount --- of data to parse. If your parser reaches the end of a fragment of --- input and could consume more input, it will suspend parsing and --- return a 'T.Partial' continuation. --- --- Supplying the 'T.Partial' continuation with a bytestring will --- resume parsing at the point where it was suspended, with the --- bytestring you supplied used as new input at the end of the --- existing input. You must be prepared for the result of the resumed --- parse to be another 'T.Partial' continuation. --- --- To indicate that you have no more input, supply the 'T.Partial' --- continuation with an empty bytestring. --- --- Remember that some parsing combinators will not return a result --- until they reach the end of input. They may thus cause 'T.Partial' --- results to be returned. --- --- If you do not need support for incremental input, consider using --- the 'I.parseOnly' function to run your parser. It will never --- prompt for more input. --- --- /Note/: incremental input does /not/ imply that attoparsec will --- release portions of its internal state for garbage collection as it --- proceeds. Its internal representation is equivalent to a single --- 'ByteString': if you feed incremental input to a parser, it will --- require memory proportional to the amount of input you supply. --- (This is necessary to support arbitrary backtracking.) - --- $performance --- --- If you write an attoparsec-based parser carefully, it can be --- realistic to expect it to perform similarly to a hand-rolled C --- parser (measuring megabytes parsed per second). --- --- To actually achieve high performance, there are a few guidelines --- that it is useful to follow. --- --- Use the 'B.ByteString'-oriented parsers whenever possible, --- e.g. 'I.takeWhile1' instead of 'many1' 'I.anyWord8'. There is --- about a factor of 100 difference in performance between the two --- kinds of parser. --- --- For very simple byte-testing predicates, write them by hand instead --- of using 'I.inClass' or 'I.notInClass'.
