inconsistency in tags() ?

[kforner]

If I tag a repo using git2r::tag(), git2r::tags() output is a (list of) git_tabobject.

but if I add the tag using the git command: git tag toto_1, the output is a (list of) git_commitobject.

Is this expected ? (This is not documented)
My use case is to sort the tags by time (cf next issue).

Thanks.

The goal was not to make git2r identical to command line git, but being able to work with the git data structures from R and run some basic git commands. I think that the documentation says that tag returns a git_tag object and that tags return a list of git_tag objects.

Sorry I was not clear enough.
Suppose I create two tags, one using command-line git, and one using git2r::tag, then
git2r::tags output a list of two objects, one is git_tag, the other a git_commit

Thanks, for the follow up. git2r creates an annotated tag. However, it seems that git2r reads a lightweight tag as a commit. I have to look into this and see if it can be improved.

Any updates on this? I see the same behavior in git2r version 0.25.2. I'm using git2r to retrieve information about tags and having to test for, handle and align the values from the different return values adds overhead - plus the 'git commit' object that git2r returns does not include the tag name for a lightweight tag.
