Teach git name-rev to take multiple --refs stored as a string list of patterns. The list of patterns will be matched inclusively, and each ref only needs to match one pattern to be included. A ref will only be excluded if it does not match any of the given patterns. Additionally, if any of the patterns would allow abbreviation, then we will abbreviate the ref, even if another pattern is more strict and would not have allowed abbreviation on its own. Add tests and documentation for this change. The tests expected output is dynamically generated. This is in order to avoid hard-coding a commit object name in the test results (as the expected output is to simply leave the commit object unnamed).

NAME
|
|
----
|
|
git-name-rev - Find symbolic names for given revs
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git name-rev' [--tags] [--refs=<pattern>]
|
|
( --all | --stdin | <commit-ish>... )
|
|
|
|
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. The pattern
|
|
can be one of branch name, tag name or fully qualified ref name. If
|
|
given multiple times, use refs whose names match any of the given shell
|
|
patterns. Use `--no-refs` to clear any previous ref patterns given.
|
|
|
|
--all::
|
|
List all commits reachable from all refs
|
|
|
|
--stdin::
|
|
Transform stdin by substituting all the 40-character SHA-1
|
|
hexes (say $hex) with "$hex ($rev_name)". When used with
|
|
--name-only, substitute with "$rev_name", omitting $hex
|
|
altogether. Intended for the scripter's use.
|
|
|
|
--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 omitted from the name, matching the output
|
|
of `git-describe` more closely.
|
|
|
|
--no-undefined::
|
|
Die with error code != 0 when a reference is undefined,
|
|
instead of printing `undefined`.
|
|
|
|
--always::
|
|
Show uniquely abbreviated commit object as fallback.
|
|
|
|
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/v0.99~940
|
|
------------
|
|
|
|
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
