how to get the short hash of a commit ?

[kforner]

I did not manage to figure out how to get the short hash of a commit.
I can get it manually via: git rev-parse --short my_commit.
Is there a way using git2r ?

Thanks

Sorry, that feature is not supported in git2r.

[kforner]

not yet, or is there a reason not to ? I mean would you accept a PR for instance ?
Thanks.

A PR would be much appreciated 👍
Maybe a good starting point is https://libgit2.github.com/libgit2/#HEAD/type/git_oid_shorten
Thanks

[kforner]

ok. What I'm not sure to understand, is do I need to add all current OIDs in the repository tree in the git_oid_shorten instance ?
Otherwise I can't see how it could need to increase the length.

@kforner did you find a solution how to extract the short hash?
