Get only tags / references of a git remote repository

问题

Is it possible to get the tags / references of a repository (eg GitHub) without downloading objects / files?

My use case is in packaging the latest beta release of some software which has a long history and is therefore large to clone.

Ideally after I determine the tag that I wish to use, I can then:

git clone -b "$tag" --depth=1

回答1:

Use git ls-remote:

$ git ls-remote -t --refs <URL>

This gives output such as:

8f235769a2853c415f811b19cd5effc47cc89433        refs/tags/continuous
24e666ed73486a2ac65f09a1479e91e6ae4a1bbe        refs/tags/continuous-develop
7c2cff2c26c1c2ad4b4023a975cd2365751ec97d        refs/tags/v2.0
35b69eed46e5b163927c78497983355ff6a5dc6b        refs/tags/v2.0-beta10

You probably also want to pass --exit-code to ensure a non-0 exit when no matching refs are returned.

To get only the tag names, pass through:

sed -E 's/^[[:xdigit:]]+[[:space:]]+refs\/tags\/(.+)/\1/g':

$ git ls-remote -t --exit-code --refs https://github.com/robert7/nixnote2.git \
  | sed -E 's/^[[:xdigit:]]+[[:space:]]+refs\/tags\/(.+)/\1/g'
continuous
continuous-develop
v2.0
v2.0-beta10

Suggestions:

Pass --exit-code to ensure a non-0 exit when no matching refs are returned.
Use the https:// version: it's faster and if you're packaging you don't want to run the risk of being asked for a ssh key.
--sort=-v:refname to sort by version rather than lexographically, and have the largest versions at the top
Use git -c versionsort.suffix=- to prevent 2.0-rc coming "after" 2.0
Add a pattern at the end of the command line to filter. Eg 'v*' if all version tags start with a v.
