Get Older Versions of Standalone Tarball

[WammKD]

Is there a way to get specific versions of the standalone tarball? I'd love to package this for Guix but package management, there, tries to be deterministic and I can't guarantee that if I can't guarantee what I'm downloading is the exact same thing I downloaded from a URL as last time.

I've managed to get it run so, with being able to point at a particular version number to download, I could create a package of this and make it easier for other users to download and use, as well.

@WammKD, we apologize for the belated response here.

Can you let us know if this still relevant and what will you need from us? Do you need to be able to download specific versions of the tarball and not the last one available on the stable channel?

Thanks for getting back!

I was trying to package the Heroku CLI for the Linux distribution GNU Guix as its non-standard file structure makes the binary need a little tweaking before it'll work (while a package could do that for whomever's downloading it); ideally, I'd do a package that builds from source but Guix doesn't, yet, have enough JS support in place to work with Yarn or Lerna, yet.

I think I have a package which can build from the binary Tarball but it's basically a constantly moving target, if I'm always pointing to the latest version. If I could specify which version, I could make available a stable package of the Heroku CLI for Guix, I think.

So, in terms of what I need, basically what you said: being able to download specific versions of the Tarball. Ideally, just a URL I can link to, and download from, to ready the binary (similarly to how I can do that, now, with the latest CLI version).

There's a JSON file always located at https://cli-assets.heroku.com/versions/heroku-linux-x64-tar-gz.json that contains a list of versions and download URLs for the tarballs. Do you think that would be helpful to get you started?

Thanks! I suspect yes (sounds like the type of thing I was looking for but, for the life of me, couldn't seem to find it) but my laptop just bit the dust a few days ago so I can't thoroughly check, quite yet.

Once I've got a working computer again, I'll check for sure and report back here.
