Feature - CREATE_INITIAL_VERSION

[Jared-Hinze]

Hello,

I may be missing something obvious, but I believe I've noticed when beginning with a brand new repo that has no pre-existing tags that this github action fails to create the INITIAL_VERSION specified as a tag of its own. Instead, it creates the next tag version after the INITIAL_VERSION. I think it would be nice to allow users to create that specified tag to reduce extra code in workflows to check and do these things through other actions or scripts.

Given a new repository with no branches and an action configured simply as:

- name: AutoTagger
  id: tagger
  uses: anothrNick/github-tag-action@1.73.0
  env:
    INITIAL_VERSION: "1.0.0"
    TAG_PREFIX: v

your current code on line 136...

tag_commit=$(git rev-list -n 1 "$tag" || true )

...will produce the following error...

fatal: ambiguous argument 'v1.0.0': unknown revision or path not in the working tree.

...yet I will still get this v1.1.0 tag...

Bumping tag v1.0.0 - New tag v1.1.0
EVENT: creating local tag v1.1.0
EVENT: pushing tag v1.1.0 to origin

I believe this would be the ideal location to create the $tag...

#pseudo-ish code
create_initial_version=${CREATE_INITIAL_VERSION:-true}
...
tag_commit=$(git rev-list -n 1 "$tag" || true )
if [ $? -ne 0 ] && create_initial_version && !dryrun
then
    <create and push $tag>
    exit 0
fi

Thoughts?

For reference - to achieve what I'm thinking might be easily accomplished within this action I have something similar to my above description here:

jobs:
  generate_tag:
    name: Create next Release tag

    runs-on: ubuntu-latest

    outputs:
      tag: ${{ steps.tagN.outputs.new_tag || steps.tag1.outputs.new_tag }}

    permissions:
      contents: write

    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      INITIAL_VERSION: "1.0.0"
      TAG_PREFIX: v

    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4

      - name: Get tag metadata
        id: tagger
        uses: anothrNick/github-tag-action@1.73.0
        env:
          DRY_RUN: true

      - name: Check if tag exists
        uses: mukunku/tag-exists-action@v1.6.0
        id: check_tag
        with:
          tag: "${{ steps.tagger.outputs.old_tag }}"

      - name: Create first tag
        id: tag1
        if: ${{ steps.check_tag.outputs.exists == 'false' }}
        uses: anothrNick/github-tag-action@1.73.0
        env:
          CUSTOM_TAG: "${{ steps.tagger.outputs.old_tag }}"

      - name: Create next tag
        id: tagN
        if: ${{ steps.check_tag.outputs.exists == 'true' }}
        uses: anothrNick/github-tag-action@1.73.0
