Project description
purl2vcs is an add-on library working with the PurlDB to find the version control system (VCS) URL of a package and detect the commit, and tags for a given version.
In the future, it will also find paths and branches, which is useful for monorepos.
Usage
First, import the main module: from purl2vcs import find_source_repo
To use the functions you first need to acquire some Package objects: Use the get_package_object_from_purl(package_url) passing a PURL string to get an object from the database
To find the source repository of a Package, call get_source_repo(package) to will get a PackageURL object back.
To generate all the source repository URLs of a Package, call get_repo_urls(package).
To convert a single source repo URLs to PURLs, call convert_repo_url_to_purls
To convert a list of source repo URLs to PURLs, call convert_repo_urls_to_purls
To find the commit or tags from a source repo PURL use get_tags_and_commits
The low level get_tags_and_commits is used in find_package_version_tag_and_commit to find the tag and commit of a given package version in a source repo PURL.
