180 Various values from structured fields in referenced objects can be used to interpolate into the resulting output, or as sort keys\&.

182 For all objects, the following names can be used:
183 .PP
184 refname

186 The name of the ref (the part after $GIT_DIR/)\&. For a non\-ambiguous short name of the ref append
187 \fB:short\fR\&. The option core\&.warnAmbiguousRefs is used to select the strict abbreviation mode\&. If

190 \fB<N>\fR
191 slash\-separated path components from the front (back) of the refname (e\&.g\&.
192 \fB%(refname:lstrip=2)\fR

276 For any remote\-tracking branch
277 \fB%(upstream)\fR,
278 \fB%(upstream:remotename)\fR
279 and
280 \fB%(upstream:remoteref)\fR
281 refer to the name of the remote and the name of the tracked remote ref, respectively\&. In other words, the remote\-tracking branch can be updated explicitly and individually by using the refspec

For email fields (\fBauthoremail\fR, \fBcommitteremail\fR and \fBtaggeremail\fR), \fB:trim\fR can be appended to get the email without angle brackets, and \fB:localpart\fR to get the part before the \fB@\fR symbol out of the trimmed email\&.

645 Note that the sizes of objects on disk are reported accurately, but care should be taken in drawing conclusions about which refs or objects are responsible for disk usage\&. The size of a packed non\-delta object may be much larger than the size of objects which delta against it, but the choice of which object is the base and which is the delta is arbitrary and is subject to change during a repack\&.
646 .sp
647 Note also that multiple copies of an object may be present in the object database; in this case, it is undefined which copy\(cqs size or delta base will be reported\&.
