如何在git中查找GitHub发布标签是否已预发布？

Question

While creating the release in github, i have checked the checkbox for pre-release. So in the releases page this tag is marked as pre-release. (with a red color label)

now I am checking out the release to local a

git fetch upstream
git checkout -b release-v1.0 release-v1.0

now I want to know if the release is a pre-release or not in the local machine. Is there a command for doing this this?

Answer 1

GitHub Releases are an additional feature on top of git tags. Same as for Pull Request, Issues, and Forks, there is no such concept in git.

When you create a release a new git tag will be created with the same name. But all the properties like

• Release name
• Description
• Pre-release satus

Are attached to the release, not to the tag.

You can poll GitHub API for an additional info:

GET /repos/:owner/:repo/releases/:id

{
 ...
  "prerelease": false
}

You can use command-line wrapper hub https://github.com/github/hub which will hide http calls for you.

Some commands like hub release show should work for you.

Just in case if you hit the rate limit (I am working in a large software shop) so it's almost impossible to use API requests (without authorization). My Goal was was to check is get the last stable release into our ci/cd pipeline.

function get_recent_stable_relese(){
    URL=$(curl -Ls -o /dev/null -w %{url_effective} $1)
    VERSION=$(basename ${URL})
    if [[ -z $VERSION ]]; then
        exit 1;
    fi
    echo $VERSION
    exit 0;
}

BOX_LATEST_RELEASE=http://github.com/box/box-content-preview/releases/latest
echo $(get_recent_stable_relese ${BOX_LATEST_RELEASE})

so latest becomes last release version which you can use to checkout code.
