Often users want to know not which tagged version a commit came after, but which tagged version a commit is contained within. This latter task is the job of git-name-rev, but most users are looking to git-describe to do the job. Junio suggested we make `git describe --contains` run the correct tool, `git name-rev`, and that's exactly what we do here. The output of name-rev was adjusted slightly through the new --name-only option, allowing describe to execv into name-rev and maintain its current output format. Signed-off-by: Shawn O.

NAME
|
|
----
|
|
git-name-rev - Find symbolic names for given revs
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git-name-rev' [--tags] [--refs=<pattern>]
|
|
( --all | --stdin | <committish>... )
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Finds symbolic names suitable for human digestion for revisions given in any
|
|
format parsable by git-rev-parse.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--tags::
|
|
Do not use branch names, but only tags to name the commits
|
|
|
|
--refs=<pattern>::
|
|
Only use refs whose names match a given shell pattern.
|
|
|
|
--all::
|
|
List all commits reachable from all refs
|
|
|
|
--stdin::
|
|
Read from stdin, append "(<rev_name>)" to all sha1's of nameable
|
|
commits, and pass to stdout
|
|
|
|
--name-only::
|
|
Instead of printing both the SHA-1 and the name, print only
|
|
the name. If given with --tags the usual tag prefix of
|
|
"tags/" is also ommitted from the name, matching the output
|
|
of gitlink::git-describe[1] more closely. This option
|
|
cannot be combined with --stdin.
|
|
|
|
EXAMPLE
|
|
-------
|
|
|
|
Given a commit, find out where it is relative to the local refs. Say somebody
|
|
wrote you about that fantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a.
|
|
Of course, you look into the commit, but that only tells you what happened, but
|
|
not the context.
|
|
|
|
Enter git-name-rev:
|
|
|
|
------------
|
|
% git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a
|
|
33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99^0~940
|
|
------------
|
|
|
|
Now you are wiser, because you know that it happened 940 revisions before v0.99.
|
|
|
|
Another nice thing you can do is:
|
|
|
|
------------
|
|
% git log | git name-rev --stdin
