ls-remote: create '--sort' option
Create a '--sort' option for ls-remote, based on the one from for-each-ref. This e.g. allows ref names to be sorted by version semantics, so that v1.2 is sorted before v1.10. Signed-off-by: Harald Nordgren <haraldnordgren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

DESCRIPTION

@ -60,6 +60,16 @@ OPTIONS
|
||||
upload-pack only shows the symref HEAD, so it will be the only
|
||||
one shown by ls-remote.
|
||||
|
||||
--sort=<key>::
|
||||
Sort based on the key given. Prefix `-` to sort in descending order
|
||||
of the value. Supports "version:refname" or "v:refname" (tag names
|
||||
are treated as versions). The "version:refname" sort order can also
|
||||
be affected by the "versionsort.suffix" configuration variable.
|
||||
See linkgit:git-for-each-ref[1] for more sort options, but be aware
|
||||
keys like `committerdate` that require access to the objects
|
||||
themselves will not work for refs whose objects have not yet been
|
||||
fetched from the remote, and will give a `missing object` error.
|
||||
|
||||
<repository>::
|
||||
The "remote" repository to query. This parameter can be
|
||||
either a URL or the name of a remote (see the GIT URLS and
