This package provides a mocking framework which integrates well with built-in testing package, but can be used in other contexts too.

This package defines basic interfaces to handle tar files. It is similar to fs.FS, but for tar files.

This package provides a library for reading RAR archives with Golang.

Package extract allows to extract archives in zip,tar.gz or tar.bz2 formats easily.

This package provides a library for reading RAR archives with Golang.

Package lzip implements the lzip compressed format and supports reading and writing of lzip compressed streams.

This package provides a Go implementation of the Snappy compression format.

This package provides a multi-format Go library for working with archives and compression formats with a unified API and as virtual file systems compatible with io/fs.

lz4 provides a streaming interface to LZ4 data streams as well as low level compress and uncompress functions for LZ4 data blocks. The implementation is based on the reference C one.

This package implements reader/writer library eStargz - a lazily-pullable image format.

This package is an implementation of Roaring bitmaps as described at https://roaringbitmap.org/about/ in Go. Roaring bitmaps are fast compressed bitmap data structures (also called bitset). They are ideally suited to represent sets of integers over relatively small ranges.

This package provides a Golang file reader for archive files generated with ar.

Package compress is a collection of compression libraries implementing Golang modules:

brotli

Implements the Brotli format, described in RFC 7932.

bzip2

Implements the BZip2 compressed data format.

flate

Implements the DEFLATE format, described in RFC 1951.

xflate

Implements the XFLATE format, an random-access extension to DEFLATE.

compress provides various compression algorithms.

Package archiver facilitates convenient, cross-platform, high-level archival and compression operations for a variety of formats and compression algorithms.

Features:

• stream-oriented APIs

• automatically identify archive and compression formats

• traverse directories, archive files, and any other file uniformly as io/fs file systems

• compress and decompress files

• create and extract archive files

• walk or traverse into archive files

• extract only specific files from archives

• insert (append) into .tar and .zip archives

• read from password-protected 7-Zip files

• numerous archive and compression formats supported

• extensible (add more formats just by registering them)

• cross-platform, static binary

• pure Golang (no cgo)

• multithreaded Gzip

• adjust compression levels

• automatically add compressed files to zip archives without re-compressing

• open password-protected rar archives

Supported compression formats:

• brotli (.br)

• bzip2 (.bz2)

• flate (.zip)

• gzip (.gz)

• lz4 (.lz4)

• lzip (.lz)

• snappy (.sz)

• xz (.xz)

• zlib (.zz)

• zstandard (.zst)

Supported archive formats:

• .zip

• .tar (including any compressed variants like .tar.gz)

• .rar (read-only)

• .7z (read-only)

This package implements a functionality for pristinely disassembling a tar archive, and stashing needed raw bytes and offsets to reassemble a validating original archive.

This package implements a functionality for pristinely disassembling a tar archive, and stashing needed raw bytes and offsets to reassemble a validating original archive.

This package implements a native XZ decompression in Golang.

This package provides a support of reading and writing of xz compressed streams. It includes also a gxz command for compressing and decompressing data. The package is completely written in Go and doesn't have any dependency on any C code.

MinLZ is a LZ77-type compressor with a fixed byte-aligned encoding, in the similar class to Snappy and LZ4.

Package sevenzip provides read access to 7-zip archives inspired by std archive/zip. It is implemented in pure Go without external libraries or binaries needed.

Package archive provides helper functions for dealing with archive files.

This package provides a library for encoding and decoding ZIP archive format's "Extra Fields". The intention is to eventually support and provide a low-level API for the majority of PKWARE's and Info-ZIP's extra fields.

Package zip provides support for reading and writing ZIP archives.
