This source package is a collection of utilities intended to make it easier for Go programs to work with System Package Data Exchange files. It currently works with files conformant to versions 2.1, 2.2 and 2.3 of the SPDX specification and provides the following packages:

• spdx - in-memory data model for the sections of an SPDX document

• tagvalue - tag-value document reader and writer

• rdf - RDF document reader

• json - JSON document reader and writer

• yaml - YAML document reader and writer

• builder - builds empty SPDX document (with hashes) for directory contents

• idsearcher - searches for SPDX short-form IDs and builds an SPDX document

• licensediff - compares concluded licenses between files in two packages

• reporter - generates basic license count report from an SPDX document

• spdxlib - various utility functions for manipulating SPDX documents in memory

• utils - various utility functions that support the other tools-golang packages

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)
