From f127404c45eff139037834a6464b68fbe1798e16 Mon Sep 17 00:00:00 2001 From: Andy Parkins Date: Fri, 26 Jan 2007 14:28:55 +0000 Subject: [PATCH] If abbrev is set to zero in git-describe, don't add the unique suffix When on a non-tag commit, git-describe normally outputs descriptions of the form v1.0.0-g1234567890 Some scripts (for example the update hook script) might just want to know the name of the nearest tag, so they then have to do x=$(git-describe HEAD | sed 's/-g*//') This is costly, but more importantly is fragile as it is relying on the output format of git-describe, which we would then have to maintain forever. This patch adds support for setting the --abbrev option to zero. In that case git-describe does as it always has, but outputs only the nearest found tag instead of a completely unique name. This means that scripts would not have to parse the output format and won't need changing if the git-describe suffix is ever changed.
