# Ruby version determination

Determine the Ruby versions for your testing matrix based on the gemspec.

Maintaining your CI is tedious and your gem can already specify the compatible Ruby versions using [required_ruby_version](https://guides.rubygems.org/specification-reference/#required_ruby_version).

This action reads your gemspec and provides an output of compatible Ruby versions.

## Supported Ruby versions

A static list of compatible versions is maintained.

This is a subset of [setup-ruby's supported versions](https://github.com/ruby/setup-ruby#supported-versions).

* 3.4

* 3.3

* 3.2

* 3.1

* 3.0

* 2.7

* 2.6

* 2.5

* 2.4

## Example

A minimal example has a single job to determine the Ruby version matrix, using this repository.

Then there should be some task that uses the matrix, but the exact steps likely differ.

```yaml

jobs:

  setup_matrix:

    name: "Determine Ruby versions"

    runs-on: ubuntu-latest

    outputs:

      ruby: ${{ steps.ruby.outputs.versions }}

    steps:

      - id: ruby

        uses: voxpupuli/ruby-version@v1

  test:

    name: "Ruby ${{ matrix.ruby }}"

    runs-on: ubuntu-latest

    needs: setup_matrix

    strategy:

      matrix:

        ruby: ${{ fromJSON(needs.setup_matrix.outputs.ruby) }}

    steps:

      - uses: actions/checkout@v4

      - name: Setup ruby

        uses: ruby/setup-ruby@v1

        with:

          ruby-version: ${{ matrix.ruby }}

          bundler-cache: true

      - name: Run tests

        run: bundle exec rake test

```
