I would like to retain (for now) the ability to link Git changesets to workitems stored in TFS.
I already wrote a tool (using a hook from Git) in which I can inject workitemidentifiers into the message of a Git changeset.
However, I would also like to store the identifier of the Git commit (the hash) into a custom TFS workitem field. This way I can examine a workitem in TFS and see what Git changesets are associated with the workitem.
How can I easily retrieve the hash from the current commit from Git?
To turn arbitrary extended object reference into SHA-1, use simply git-rev-parse, for example
git rev-parse HEAD
git rev-parse --verify HEAD
Sidenote: If you want to turn references (branches and tags) into SHA-1, there is
git show-ref and
