This is a small action which captures some logic I'd find myself needing in lots of different workflows.
Firstly, I wanted to retrieve the tag corresponding to the commit for the current workflow, and perform some action if this is a "tag workflow".
For example, I like to tag my Docker images with the git tag if there is one, else I tag the images with latest.
Or, you may want to automatically create a GitHub release corresponding to each tag, using actions/create-release.
Secondly, I often want to get the short commit SHA (conventionally the first 7 characters).
| Name | Description | Default |
|---|---|---|
| working_directory | Working directory in which to run git commands. |
Defaults to current working directory. |
| Name | Description |
|---|---|
| branch | HEAD branch. Empty if the current ref is a tag. |
| is_pr | 'true' if this is a PR workflow, else 'false'. |
| pr_head | The pull request head ref (the ref the PR is "coming from"). Empty if (!is_pr). |
| pr_base | The pull request base ref (the ref that is "receiving" the PR). Empty if (!is_pr). |
| short_sha | The first 7 characters of the HEAD commit. |
| tags | All tags that point at the HEAD commit. If there are no tags, this is the empty string. If there are multiple tags, they are sorted alphabetically and separated by spaces. |
| tag | If tags is not empty, this is the first tag alphabetically. This way, you can know that this output contains exactly one tag, or the empty string. |
| tags_count | The integer number of tags. |
