Hopfli - Haskell bindings to the Zopfli library

Build Status Hackage-Deps Hackage License

Hopfli provides a pure interface to compress data using the Zopfli library.

Zopfli is a compression library released by Google in 2013, which can output either a raw DEFLATE stream, or one wrapped into zlib or gzip formats. Under default settings, the output produced by Zopfli is 3.7–8.3% smaller than that of gzip -9, though the algorithm is 81 times slower.

Example

import           Codec.Compression.Hopfli
import           Data.ByteString
import           System.IO                (stdin, stdout)

main :: IO ()
main = hGetContents stdin >>= hPut stdout . compressWith defaultCompressOptions GZIP
