Do not use branch names, but only tags to name the commits

Only use refs whose names match a given shell pattern. The pattern can be a branch name, a tag name, or a 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.

Do not use any ref whose name matches a given shell pattern. The pattern can be one of branch name, tag name or fully qualified ref name. If given multiple times, a ref will be excluded when it matches any of the given patterns. When used together with --refs, a ref will be used as a match only when it matches at least one --refs pattern and does not match any --exclude patterns. Use --no-exclude to clear the list of exclude patterns.

List all commits reachable from all refs

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. This option was called --stdin in older versions of Git.

$ cat sample.txt

An abbreviated revision 2ae0a9cb82 will not be substituted.
The full name after substitution is 2ae0a9cb8298185a94e5998086f380a355dd8907,
while its tree object is 70d105cc79e63b81cfdcb08a15297c23e60b07ad

$ git name-rev --annotate-stdin <sample.txt

An abbreviated revision 2ae0a9cb82 will not be substituted.
The full name after substitution is 2ae0a9cb8298185a94e5998086f380a355dd8907 (master),
while its tree object is 70d105cc79e63b81cfdcb08a15297c23e60b07ad

$ git name-rev --name-only --annotate-stdin <sample.txt

An abbreviated revision 2ae0a9cb82 will not be substituted.
The full name after substitution is master,
while its tree object is 70d105cc79e63b81cfdcb08a15297c23e60b07ad

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.

Die with error code != 0 when a reference is undefined, instead of printing undefined.

Show uniquely abbreviated commit object as fallback.
