No problem buddy!
I'll probably have a couple other tiny PRs too, just to help us use it

@pombredanne
@DarthHater even more awesome :bow:

Hey @pombredanne - re PEP-561 typing (and beyond the official Rationale), we had a few downstream folk request us type the CycloneDX Python LIb as they had tools like mypy in their CI processes and it caused extra work (headaches) for them to deal with un-typed dependencies.

tldr: Hygiene I guess?

Re: help @pombredanne - is this the best place to talk specifically about the Python library?
Philippe Ombredanne
@pombredanne
@madpah sure thing
@madpah I feel that typed Python is another language at times and not my Python :P
but I can live with it as long as we are still supporting Python 3.6+ for now
so please go for it :+1:
Paul Horton
@madpah
Sure @pombredanne - will look at a PR then for typing a’la PEP-561
What CI is actually used for package-url Python @pombredanne ? It’s not clear from the repo?
Philippe Ombredanne
@pombredanne
@madpah I am ashamed
package-url/packageurl-python#83
The CI seem to be gone entirely :)
Paul Horton
@madpah
Oh dear. Any objection to me getting GitHub Actions or Circle CI up and running for it?
Philippe Ombredanne
@pombredanne
I will merge in a skeleton I use elsewhere with a decent CI setup and enable Azure + Appveyor at least
Paul Horton
@madpah
Sure - whatever you prefer.

@madpah perfect too

@madpah please go for it :)
Paul Horton
@madpah
Will do @pombredanne
Might need to get some permissions on the main https://github.com/package-url/packageurl-python repo @pombredanne
Philippe Ombredanne
@pombredanne
@madpah unrelated I think you found some use for https://github.com/nexB/pip-requirements-parser in some CycloneDX lib of yours and this sia wesome
Paul Horton
@madpah
We did @pombredanne !
Philippe Ombredanne
@pombredanne
@madpah Let me give you some access as you need. I guess you can be trusted as a committer?
@madpah done :)

@pombredanne PR for enabling GitHub Actions is with you for review (merging is blocked for me until 1 approver :-))

Anyone know why the python package isn't letting me get a url from a purl?

@app.command()
def get(purl: str):
    parsed = PackageURL.from_string(purl)
    typer.echo(f"Grabbing {parsed}")
    typer.echo("A", purl2url.get_url(purl))
    typer.echo("B", purl2url.get_url(parsed.to_string()))
    typer.echo("C", purl2url.get_url(str(parsed)))
    typer.echo("D", purl2url.get_url(parsed.to_string()))

For this I've tried the two following PURLs:

And for both of them I successfully parse and can print the purl, but the A, B, C, D echos after that are all empty (but don't crash).

@pombredanne
@tclasen because it has not been implemented yet : https://github.com/package-url/packageurl-python/blob/main/src/packageurl/contrib/purl2url.py :)
It should be reasonably straightforward using tidbits of code from https://github.com/nexB/fetchcode/blob/master/src/fetchcode/package.py and the expansive set in https://github.com/nexB/scancode-toolkit/tree/develop/src/packagedcode
@tclasen can I interest you in contributing these?
@TG1999 ^ ping
@tclasen please start with an issue

@pombredanne any chance you are gonna check this out soonish? package-url/packageurl-go#32 (coworker is demoing something that relies on it right now, hence asking)

Hi, I would like to contribute, but am unsure how to go about it. I've seen an issue where a contributing.md was discussed, but never got realized.
What is the preffered way to contribute? Should I open an issue to discuss my ideas, discuss them here or start writing the specifications I think are needed and then discuss in the PR?
Specifically I'm looking into creating an SBOM for a Windows 10 System and would like to add a type for Store Apps. The data you can get on those is very uniform and it should be easy to create a specification for those.
Philippe Ombredanne
@pombredanne
@ChronosMOT Hey :) for this the best is to start with a PR adding a type. That's the simplest and this is usually fairly straightforward .... BTW is there a way to directly download Store Apps? just curious?
ChronosMOT
@ChronosMOT
Hi @pombredanne . Ok, then I'll do that.
Appearantly there is https://lazyadmin.nl/it/install-microsoft-store-apps-without-store/ ^^
Philippe Ombredanne
@pombredanne
great :+1: that's best
I assume that there is likely some recipe to automatically derive these
ChronosMOT
@ChronosMOT
Well... After a quick try it seems that there is a website that lists the download-link for the app-package for each product on the store. There isn't really a good way to get to that download-link...
So you can download it apps without using the store, but it gets a bit involved ^^"

@pombredanne
if there is a will, there is a way! :)

I'm attempting to create an open-source universal downloader of sorts, based on PURL's. I've done this before in another life, and it was a PITA to come up with all the different URI's for the various artifact providers, the package-url spec seems very similar to what we ended up creating in house, and I'd love to build ontop of it.

Couple of questions:

  • is there already a known tool that will download artifacts given a PURL? (preferably a standalone binary written in Go?)
  • my first use-case is to download a github release asset (scrutiny-collector-metrics-windows-4.0-amd64.exe attached to this release https://github.com/AnalogJ/scrutiny/releases/tag/v0.4.8), is there a existing PURL format for something like that?
  • if not, which of the following would make the most sense?
    • pkg:github/AnalogJ/scrutiny@v0.4.8?file_name=scrutiny-collector-metrics-windows-4.0-amd64.exe&type=release_asset
    • pkg:github/AnalogJ/scrutiny@v0.4.8?type=release_asset#scrutiny-collector-metrics-windows-4.0-amd64.exe
