Release Changes

GitHub Actions for checking changes between releases.

Changes are found by looking at new commits from the latest tag on the workflow branch. This can be helpful for skipping upload of sheduled builds etc. and an alternative to always upload on push.

Usage

Below is an example of skipping upload of releases to GitHub for sheduled builds and workflow dispatch triggers when no new commits have been added since last release. Pull requests will always indicate no changes.

name: ci

on:
  workflow_dispatch:
  schedule:
    - cron: '0 18 * * 1-5'
  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Build
        run: ./build.sh
      - name: Check release changes
        uses: polytech-com/release-changes-action@v2
        id: release
      - name: Upload to GitHub
        uses: softprops/action-gh-release@v1
        if: ${{ steps.release.outputs.changes == 'true' }}
        with:
          target_commitish: ${{ github.sha }}
