Abort git merge using libgit2sharp

Question

In libgit2sharp I'm doing a fetch and merge for an upstream branch, and I want to be able to abort the merge similar to:

git merge --abort

when the MergeStatus is:

LibGit2Sharp.MergeStatus.Conflicts

Is this currently possible (using v.0.20.1)? If not, does anybody know what it would require to implement something like that?

Answer 1

The git-merge --abort command is shorthand for git reset --merge, and both a git-reset --merge and a git-reset --hard will abort the merge and clean up the repository, differing in how they update modified files.

LibGit2Sharp does not currently offer a reset parallel to the merge option. However if you use the Repository.Reset method with the ResetMode.Hard option your merge will be aborted (though with git-reset --hard semantics).
