Usage
=====
::
>>> from packageurl import PackageURL
>>> purl = PackageURL.from_string("pkg:maven/org.apache.commons/io@1.3.4")
>>> print(purl.to_dict())
{'type': 'maven', 'namespace': 'org.apache.commons', 'name': 'io', 'version': '1.3.4', 'qualifiers': None, 'subpath': None}
>>> print(purl.to_string())
pkg:maven/org.apache.commons/io@1.3.4
>>> print(str(purl))
pkg:maven/org.apache.commons/io@1.3.4
>>> print(repr(purl))
PackageURL(type='maven', namespace='org.apache.commons', name='io', version='1.3.4', qualifiers={}, subpath=None)
Utilities
=========
Django models
^^^^^^^^^^^^^
`packageurl.contrib.django.models.PackageURLMixin` is a Django abstract model mixin to
use Package URLs in Django.
SQLAlchemy mixin
^^^^^^^^^^^^^^^^
`packageurl.contrib.sqlalchemy.mixin.PackageURLMixin` is a SQLAlchemy declarative mixin
to use Package URLs in SQLAlchemy models.
URL to PURL
^^^^^^^^^^^
`packageurl.contrib.url2purl.get_purl(url)` returns a Package URL inferred from an URL.
::
>>> from packageurl.contrib import url2purl
>>> url2purl.get_purl("https://github.com/package-url/packageurl-python")
PackageURL(type='github', namespace='package-url', name='packageurl-python', version=None, qualifiers={}, subpath=None)
PURL to URL
^^^^^^^^^^^
- `packageurl.contrib.purl2url.get_repo_url(purl)` returns a repository URL inferred
from a Package URL.
- `packageurl.contrib.purl2url.get_download_url(purl)` returns a download URL inferred
from a Package URL.
- `packageurl.contrib.purl2url.get_inferred_urls(purl)` return all inferred URLs
(repository, download) from a Package URL.
::
>>> from packageurl.contrib import purl2url
>>> purl2url.get_repo_url("pkg:gem/bundler@2.3.23")
"https://rubygems.org/gems/bundler/versions/2.3.23"
>>> purl2url.get_download_url("pkg:gem/bundler@2.3.23")
"https://rubygems.org/downloads/bundler-2.3.23.gem"
>>> purl2url.get_inferred_urls("pkg:gem/bundler@2.3.23")
["https://rubygems.org/gems/bundler/versions/2.3.23", "https://rubygems.org/downloads/bundler-2.3.23.gem"]
Run tests
=========
Install test dependencies::
python3 thirdparty/virtualenv.pyz --never-download --no-periodic-update .
bin/pip install -e ."[test]"
Run tests::
bin/pytest tests
Make a new release
==================
- Start a new release branch
- Update the CHANGELOG.rst, AUTHORS.rst, and README.rst if needed
- Bump version in setup.cfg
- Run all tests
- Install restview and validate that all .rst docs are correct
- Commit and push this branch
- Make a PR and merge once approved
- Tag and push that tag. This triggers the pypi-release.yml workflow that takes care of
building the dist release files and upload those to pypi::
VERSION=v0.x.x
git tag -a $VERSION -m "Tag $VERSION"
git push origin $VERSION
- Review the GitHub release created by the workflow at
https://github.com/package-url/packageurl-python/releases
