A simple GitHub action to post a Slack message when a new version is released.

The following inputs briefly explained here are fully declared and documented in action.yml:

• github_token [Required] - GitHub token
• slack_token [Required] - Slack token
• channel_id [Required] - Channel ID where to post (shown in 'channel details', e.g. 'C03AA0A0A3A')
• project_name [Required] - Project name to display
• repo_owner_name [Optional] - Repository owner name
• repo_name [Optional] - Repository name
• release_tag [Optional] - Git tag of the GitHub release to announce (for example v1.2.0). When omitted, the latest release for the repository is used.

Run this action on new tag push or new release!

on:
  push:
    tags:
      - "v1*"
jobs:
  examplejob:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
          ref: main
      - name: Notify new release on Slack
        uses: brainfish-ai/slack-notify-release
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          slack_token: ${{ secrets.SLACK_TOKEN }}
          channel_id: C03AA0A0A3A
          project_name: My Project

To announce a specific release instead of the latest one, set release_tag (it must match an existing release’s tag name):

      - name: Notify new release on Slack
        uses: brainfish-ai/slack-notify-release
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          slack_token: ${{ secrets.SLACK_TOKEN }}
          channel_id: C03AA0A0A3A
          project_name: My Project
          release_tag: ${{ github.ref_name }}

On a workflow triggered by push tags, github.ref_name is the tag that was pushed (for example v1.0.0).
