[back to package description]

streamly-zip

Stream data from zip archives using the Haskell streamly library.

Comparison with streamly-archive

This library was created because libarchive (which streamly-archive relies on) does not seem to have support for jumping to specific files even when the format supports it.

Requirements

Install libzip on your system.

Quick start

module Main where

import qualified Data.ByteString as B
import Data.Function
import qualified Streamly.Data.Fold as F
import qualified Streamly.Data.Stream.Prelude as S
import Streamly.External.Zip

main :: IO ()
main = do
  -- Obtain an archive.
  z <- openZip "/path/to/archive.zip" []

  -- Output a particular file to stdout.
  S.unfold unfoldFileAtPath (z, [], "file.txt")
    & S.mapM B.putStr
    & S.fold F.drain
