gracjanpolak:
I'm happy to announce a ReadP style parser for ByteStrings,
Text.ParserCombinators.ReadP.ByteString.
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bytestringreadp
Text.ParserCombinators.ReadP.ByteString is an adaptation of
Text.ParserCombinators.ReadP to work over Data.ByteString as input
stream representation. This gives enormous improvements in terms of
parsing speed but most significantly in memory usage.
Features:
* ReadP style parser over ByteString input
* Drop-in replacement for Text.ParserCombinators.ReadP
* Fast
* Good memory usage
The algorithm is slightly modified to exploit ByteString as random access
data input structure. Unlike original ReadP, that stressed garbage collection
very much by creating a lot of conses (:), this parser has very good memory
allocation behaviour.
Package works out of the box with GHC 6.8.1, with slight (cabal) modifications
also with GHC 6.6.1.
Thanks to everyone for their support! Happy hacking!
Great work, Gracjan. I hope to try it out soon. I think this is the
first of the many bytestring parser projects started to actually get
released onto Hackage! Well done!
