Package Flags

Use the -f option with cabal commands to enable flags

    non-blocking-ffi (on by default)

    The (de)compression calls can sometimes take a long time, which prevents other Haskell threads running. Enabling this flag avoids this unfairness, but with greater overall cost.

    pkg-config (on by default)

    Use pkg-config executable to locate foreign zlib library.

    bundled-c-zlib (off by default)

    Use zlib-clib package with C sources instead of a system library. C sources are used for GHCJS and WASM unconditionally and on Windows unless pkg-config flag is on.

zlib CI Hackage

Compression and decompression in the gzip and zlib format

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the zlib, gzip and raw compression formats.

It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.
