仅获取git远程存储库的标签/引用 [英] Get only tags / references of a git remote repository

问题描述

是否可以在不下载对象/文件的情况下获取存储库(例如GitHub)的标签/引用?

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

我的用例是包装某些软件的最新Beta版本，这些软件具有悠久的历史，因此很容易克隆.

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

理想的是，在确定要使用的标签之后，我可以:

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

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

推荐答案

使用 git ls-remote :

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

这将给出如下输出:

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

您可能还希望通过--exit-code，以确保在没有匹配的引用返回时非0退出.

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

要仅获取标签名称，请传递:

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

建议:

• 传递--exit-code以确保在没有匹配的引用返回时退出非0的情况.
• 使用https://版本:速度更快，并且如果您要打包，则不想冒被要求输入ssh密钥的风险.
• --sort=-v:refname按版本而不是按字母顺序排序，并且顶部具有最大的版本
• 使用git -c versionsort.suffix=-防止2.0-rc在"2.0
之后"
• 在命令行末尾添加一个模式以进行过滤.例如，如果所有版本标签均以v开头，则为'v*'.

• 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.
