Package gotesttools is a collection of packages to augment testing and support common patterns.

Packages:

• assert - compare values and fail the test when a comparison fails

• env - test code which uses environment variables

• fs - create temporary files and compare a filesystem tree to an expected value

• golden - compare large multi-line strings against values frozen in golden files

• icmd - execute binaries and test the output

• poll - test asynchronous code by polling until a desired state is reached

• skip - skip a test and print the source code of the condition used to skip the test

This package provides an idiomatic Go retry module.

The Go XML Formatter, xmlfmt, will format the XML string in a readable way.

This package provides ciinfo, a tool to get details about the current Continuous Integration environment, including checking if running in a CI system, which CI system, build id, and more.

This is a reimplementation of ci-info in Go.

• 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)

• gzip (.gz)

• lz4 (.lz4)

• lzip (.lz)

• snappy (.sz)

• xz (.xz)

• .rar (read-only)

• .7z (read-only)

A seekable stream is a valid Zstandard stream made from one or more compressed frames followed by a final skippable frame containing a seek table. Standard Zstandard decoders can read the stream from the beginning, while Reader uses the seek table to serve Read, ReadAt, and Seek calls by uncompressed byte offset and exposes the parsed metadata through Reader.SeekTable.

The package accepts small encoder and decoder interfaces and is tested with github.com/klauspost/compress/zstd.

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 provides an command line interface (CLI) tool.

go-rpmutils is a Golang library for parsing RPM file archives. It's a slimmed version of go-rpmutils.

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.

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.

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

This package provides a Go wrapper to zstd C library.

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.

Package xz implements XZ decompression natively in Go.

This package provides some Golang interfaces for handling RPM packages, such extracting RPM header and CPIO content.

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 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.

Package rpmpack packs files to rpm files. It is designed to be simple to use and deploy, not requiring any filesystem access to create rpm files.

Fastzip is an opinionated Zip archiver and extractor with a focus on speed. Features:

• archiving and extraction of files and directories can only occur within a specified directory

• permissions, ownership (uid, gid on linux/unix) and modification times are preserved

• buffers used for copying files are recycled to reduce allocations

• files are archived and extracted concurrently

• by default, github.com/klauspost/compress/flate library is used for compression and decompression

This package implements parallel gzip compression and decompression in Golang and is fully compatible with compress/gzip from the standard library. This is beneficial for large amounts of data, say more than 1MB at a time, as otherwise the internal gzip library will likely be faster.

This package is a brotli compressor and decompressor implemented in Go. It was translated from the reference implementation (https://github.com/google/brotli) with the c2go tool at https://github.com/andybalholm/c2go.
