Is it possible to checkout the source for a specific SHA?

[tiny sorrel]

Currently, when I need to checkout the source, I do this.

// clone repository with Dagger
repo := client.Git(repoUrl)
src, err := repo.Branch("master").Tree().ID(ctx)
if err != nil {
    return err
}

And it seems that there is no such method as SHA(string) in the repo.

Is there any way that I can checkout from a specific SHA?

Hi @tiny sorrel , yes that is possible, I believe there is an optional "ref" option to Git

Oh nevermind. Perhaps it is encoded in the url now? cc @opal palm

I guess what you are looking for is something like:

client.Git(repoUrl).Commit(repoSha).Tree()

That would feel more natural

As a workaround -- You can actually pass the commit inside Branch

client.Git(repoURL).Branch(commit).Tree()

[tiny sorrel]

Ah I see. Thank you so much for the prompt answer! And one minor suggestion - could you document this behavior (workaround) in the SDK doc?

For sure! /cc @opal palm @vital wraith

Should we have an explicit commit selector? This is a bit weird because Branch, Tag and Commit all do the same thing

Tangentially: there's no way NOT to use a selector (let it pick up the default branch), I think @scarlet bridge reported the same limitation (or was it someone else?)

[scarlet bridge]

I did!

Would it make any sense to rename Branch to Ref? Or is the terminology mapping to what buildkit calls it?

@scarlet bridge that's been suggested before, I also added a short explanation as to why I prefer specific terms rather than "ref"

[scarlet bridge]

Makes sense!
