I guess I'm partly to blame here. The tar_scm source service documents that
feature in it's parameter manifest (/usr/lib/obs/services/tar_scm.service).
But I agree there is currently no easy way to introspect a service how to
really use it. That would probably be an osc feature.

If so, osc would have to pull down the .service file from the server.

But I'd settle for online documentation in the WebUI, perhaps
generated from the .service file.

The "versionformat" parameter capabilities depend on the underlying SCM. So
they look slightly different depending on that, here are some best-practice


In git's case, the tar_scm service uses --pretty-format=... A quick check of
the man-page reveals:

%ad: author date (format respects --date= option)

For --date, stackoverflow has all the answers with examples (that are also
found in the man-page):

So everything is already there.

Yes, I got what I want using %cd in versionformat.

Unfortunately the description in the .service file implies -
incorrectly - that the version string will be exactly what "git log
--pretty=format:" would give, which is *not* true. Firstly the output
is sanitised with a sed script. Secondly git is given the
--date=short option which changes the output of %cd. So just from
reading the documentation I would never have tried %cd.
