Subpackage Descriptions
single ================== license-expression ================== ``license-expression`` is a comprehensive utility library to parse, compare, simplify and normalize license expressions (such as SPDX license expressions) using boolean logic. - License: Apache-2.0 - Python: 3.9+ - Homepage: https://github.com/aboutcode-org/license-expression/ - Install: `pip install license-expression` also available in most Linux distro. Software project licenses are often a combination of several free and open source software licenses. License expressions -- as specified by SPDX -- provide a concise and human readable way to express these licenses without having to read long license texts, while still being machine-readable. License expressions are used by key FOSS projects such as Linux; several packages ecosystem use them to document package licensing metadata such as npm and Rubygems; they are important when exchanging software data (such as with SPDX and SBOM in general) as a way to express licensing precisely. ``license-expression`` is a comprehensive utility library to parse, compare, simplify and normalize these license expressions (such as SPDX license expressions) using boolean logic like in: `GPL-2.0-or-later WITH Classpath-exception-2.0 AND MIT`. It includes the license keys from SPDX https://spdx.org/licenses/ (version 3.26) and ScanCode LicenseDB (from scancode-toolkit version 32.3.1, last published on 2025-01-10). See https://scancode-licensedb.aboutcode.org/ to get started quickly. ``license-expression`` is both powerful and simple to use and is a used as the license expression engine in several projects and products such as: - AboutCode-toolkit https://github.com/aboutcode-org/aboutcode-toolkit - AlekSIS (School Information System) https://edugit.org/AlekSIS/official/AlekSIS-Core - Barista https://github.com/Optum/barista - Conda forge tools https://github.com/conda-forge/conda-smithy - DejaCode https://dejacode.com - DeltaCode https://github.com/nexB/deltacode - FenixscanX https://github.com/SmartsYoung/FenixscanX - FetchCode https://github.com/aboutcode-org/fetchcode - Flict https://github.com/vinland-technology/flict and https://github.com/vinland-technology - license.sh https://github.com/webscopeio/license.sh - liferay_inbound_checker https://github.com/carmenbianca/liferay_inbound_checker - REUSE https://reuse.software/ and https://github.com/fsfe/reuse-tool - ScanCode-io https://github.com/aboutcode-org/scancode.io - ScanCode-toolkit https://github.com/aboutcode-org/scancode-toolkit - SecObserve https://github.com/MaibornWolff/SecObserve See also for details: - https://spdx.github.io/spdx-spec/appendix-IV-SPDX-license-expressions/ ``license-expression`` is also packaged for most Linux distributions. See below. Alternative: There is no known alternative library for Python, but there are several similar libraries in other languages (but not as powerful of course!): - JavaScript https://github.com/jslicense/spdx-expression-parse.js - Rust https://github.com/ehuss/license-exprs - Haskell https://github.com/phadej/spdx - Go https://github.com/kyoh86/go-spdx - Ada https://github.com/Fabien-Chouteau/spdx_ada - Java https://github.com/spdx/tools and https://github.com/aschet/spdx-license-expression-tools Build and tests status ====================== +--------------------------+------------------------+----------------------------------+ |**Linux & macOS (Travis)**| **Windows (AppVeyor)** |**Linux, Windows & macOS (Azure)**| +==========================+========================+==================================+ | | | | | |travis-badge-icon| | |appveyor-badge-icon| | |azure-badge-icon| | | | | | +--------------------------+------------------------+----------------------------------+
