gobzip2

Pure Go implementation of bzip2 compression and decompression, based on the bzip2 1.0.8 reference C implementation.

Unlike the standard library's compress/bzip2 which only supports decompression, this package provides both compression and decompression.

Install

go get github.com/KarpelesLab/gobzip2

Usage

Compression

var buf bytes.Buffer
w := gobzip2.NewWriter(&buf)
w.Write([]byte("hello, world"))
w.Close()

Decompression

data, err := io.ReadAll(r)
