Get Tag GitHub Action

This is a simple GitHub Action that can be used to get git-tags from the repository that the action is run in. It can be used to get a list of all git-tags in the repository or to get only the newest git-tag.

Usage

In order to return the newest git-tag, the action can be used as follows:

- name: Get Tag
  uses: cmdaltent/action-get-tag@v2
  id: get-tag
- name: Print Tag
  run: echo ${{ steps.get-tag.outputs.tag }}

In order to return all git-tags, the action can be used as follows:

- name: Get Tags
  uses: cmdaltent/action-get-tag@v2
  with:
    newest_tag_only: 'false'
  id: get-tags
- name: Print Tags
  §run: echo ${{ steps.get-tags.outputs.tags }}

Both actions need the full history of the repository to be checked out. This can be achieved as follows:

- name: Checkout repository with full history
  uses: actions/checkout@v4
  with:
    fetch-depth: 0

If only the latest commit is being checked out, the action will return an empty list [] if all tags are being fetched or an empty string '' if only the latest commit is being fetched unless the latest commit contains a valid git-tag.
