GitHub Action to bump the current dotnet .csproj project version, or a part of it, to the next higher revision. Places the bumped version into a context variable for later reference.

In a GitHub Workflow that runs after pushing a tag:

name: Auto-bump-version on merging a Pull Request

on:
  pull_request:
    branches:
      - main
    types: [closed]

jobs:
  build:
    runs-on: ubuntu-latest
    if: github.event.pull_request.merged == true
    steps:
      - name: Checkout
        uses: actions/checkout@v2

      - name: Bump version
        id: package_version
        uses: KageKirin/bump-csproj-version@v0
        with:
          file: src/a_project.csproj
          patch: true

      - name: Commit new version
        run: |
          git commit -am "CI: bump version to ${{ steps.test.package_version.version }}"
          git tag -m "CI: create new tag" v${{ steps.test.package_version.version }}
          git push --follow-tags https://${{ github.token }}@github.com/OWNER/REPO

This represents the path to the .csproj to retrieve the version number from.

This is the Regular Expression used to verify the version. It defaults to an equivalent of major.minor.patch and requires all 3 integers to be present.

This is the XPath locator for the Version element. It defaults to //PropertyGroup/Version.

These 3 input variables represent the 3 levels of semantic versioning. They must be set to true or false depending on which version level you want to increment.

This the version string as retrieved from the package.json after writing to the file.

The action will fail if:

• it can't open the file
• it fails to retrieve the <Version> element
  • note that a newly created project does not contain any <Version> tag.
• the version string does not match the provided regex
