SPDX parser and tools.

Python library to to parse, validate and create SPDX documents

Linux	macOS	Windows

Information

This library implements SPDX tag/value and RDF parsers, validators and handlers in Python.

• Home: https://github.com/spdx/tools-python
• Issues: https://github.com/spdx/tools-python/issues
• Pypi: https://pypi.python.org/pypi/spdx-tools

History

This is the result of an initial GSoC contribution by @ah450 (or https://github.com/a-h-i) and is maintained by a community of SPDX adopters and enthusiasts.

License

Apache-2.0

Features

• API to create and manipulate SPDX documents.
• Parse and create Tag/Value, RDF, JSON, YAML, XML format SPDX files

TODOs

• Update to full SPDX v2.1
• Add to full license expression support

How to use

Command-line usage:

1. PARSER (for parsing any format):

• Use parser --file <filename> where <filename> is the location of the file.
  Try running : parser --file data/SPDXRdfExample.rdf.

• Or you can use parser only and then it will automatically prompt/ask for filename.

• for help - use parser --help

2. CONVERTOR (for converting one format to another):

• If I/O formats are known:

  • Use convertor --infile/-i <input_file> --outfile/-o <output_file> where <input_file> is the location of the file to be converted (Note: only RDF and Tag formated supported) and <output_file> is the location of the output file.
    Try running : convertor --infile data/SPDXRdfExample.rdf --outfile output.json

• If I/O formats are not known:

  • Use convertor --from/-f <input_format> <input_file> --to/-t <output_format> <output_file> where <input_format> is the manually enterred format of the input file (can be either rdf or tag) and <out_format> (can be tag, rdf, json, yaml, xml) is the manually enterred format of the output file. Try running : convertor --from tag data/SPDXTagExample.in --to yaml output.out

• If anyone format is known and other is not, you can use the mixture of the above two points.
  Ex. : convertor -f rdf data/SPDXRdfExample.xyz -o output.xml

• for help - use convertor --help

Installation

As always you should work in a virtualenv or venv. You can install a local clone of this repo with yourenv/bin/pip install . or install from PyPI with yourenv/bin/pip install spdx-tools. Note that on Windows it would be Scripts instead of bin.

How to run tests

Tests framework is using pytest

pip install pytest
pytest -vvs

Development process

We use the GitHub flow that is described here: https://guides.github.com/introduction/flow/

So, whenever we have to make some changes to the code, we should follow these steps:

1. Create a new branch: git checkout -b fix-or-improve-something
2. Make some changes and the first commit(s) to the branch: git commit --signoff -m 'What changes we did'
3. Push the branch to GitHub: git push origin fix-or-improve-something
4. Make a pull request on GitHub.
5. Continue making more changes and commits on the branch, with git commit --signoff and git push.
6. When done, write a comment on the PR asking for a code review.
7. Some other developer will review your changes and accept your PR. The merge should be done with rebase, if possible, or with squash.
8. The temporary branch on GitHub should be deleted (there is a button for deleting it).
9. Delete the local branch as well:

   git checkout master
   git pull -p
   git branch -a
   git branch -d fix-or-improve-something
   

Besides this, another requirement is that every change should be made to fix or close an issue: https://guides.github.com/features/issues/ If there is no issue for the changes that you want to make, create first an issue about it that describes what needs to be done, assign it to yourself, and then start working for closing it.
