Prefix not stripped from version tag

[JonasDoe]

Hey, since I can't imagine that being a bug nobody noticed yet, here's my issue in a discussion. ;) I basically try to get the version tag from steps.branch-name.outputs.tag, but instead of, say, 0.7.27, I end up with something like refs/tags/v0.7.27.
Here's the beginning of my workflow file:

name: Publish docker image for release
on:
  release:
    types: [published]

jobs:
  generate:
    name: Create release docker image
    runs-on: ubuntu-latest
    timeout-minutes: 15
    steps:
      - name: Get branch name
        id: branch-name
        uses: tj-actions/branch-names@v7.0.3
        with:
          strip_tag_prefix: true
      - name: Print version
        run: echo ${DOCKER_TAG} # Prints refs/tags/v0.7.27 instead of 0.7.27
        env:
          DOCKER_TAG: ${{ steps.branch-name.outputs.tag }}
...

Am I doing something wrong? Thank you in advance!

Hi @JonasDoe, I believe the bug is with the use of strip_tag_prefix input which is set to true as opposed to a character that you’ll like to strip from the tag which in your case wouldn’t be necessary. To resolve the bug you can remove the strip_tag_prefix input.

Well, actually I want to strip the initial "v" - it is necessary in my case. ;) But alright, if it's a real bug I can create an issue for it! Thank you so far!

@JonasDoe if you want to strip the leading v, you’ll need to explicitly pass the v to the strip_tag_prefix input.

Oh, I see! Sry for the hassle!

No worries it appears this might not be too obvious so I’ve updated the docs to reflect the changes you’ll need to make. Let me know if you run into any other issues or have any questions. Thanks
