How to checkout a bare repository?

[Reverier-Xu]

Hi, thank you for your awesome work!

I want to checkout the head commit from the bare repository to some working folder, then I wrote the code referring to the method here:

    pub fn checkout_head(&self, dst_path: impl AsRef<Path>) -> anyhow::Result<()> {
        let dst_path = dst_path.as_ref();
        let git_path = self.path.clone();
        debug!("index path: {}", git_path.join("index").as_path().display());
        let mut index = gix_index::File::at(git_path.join("index"), Sha1, Default::default())?;
        let odb = gix::odb::at(git_path.join("objects"))?
            .into_inner()
            .into_arc()?;
        let _outcome = gix_worktree::checkout(
            &mut index,
            dst_path,
            move |oid, buf| odb.find_blob(oid, buf),
            &mut progress::Discard,
            &mut progress::Discard,
            &AtomicBool::default(),
            gix_worktree::checkout::Options {
                overwrite_existing: true,
                ..Default::default()
            },
        )?;
        Ok(())
    }

But it failed with message An IO error occurred while opening the index, it seems that bare repository does not have index file.

any other ways that could do this? thank you for you help!

the method in git goes here:

git --work-tree=<working folder> --git-dir=<bare repository> checkout -f

Indices can be created on the fly by using a tree object.

However, please note that at this time the checkout implementation is nothing more than experimental, a lot of the required implementation is missing.

Further, I wonder if git worktree would be suitable for your use-case. There is also git archive if detached worktrees are desired, even though there is no gix counterpart yet.

I hope that helps.
