zlib: Compression and decompression in the gzip and zlib formats

[ bsd3, codec, library ] [ Propose Tags ]

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.

Flags

Manual Flags

NameDescriptionDefault
non-blocking-ffi

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.

Enabled
bundled-c-zlib

Use the bundled zlib C sources. For GHCJS and WASM this is the default.

Disabled
Automatic Flags
NameDescriptionDefault
pkg-config

Use pkg-config(1) to locate foreign zlib library.

Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
