matrix-extra-inputs

This action is designed to be used to augment a GitHub Actions build matrix to contain extra inputs.

This converts any environment variables starting with EXTRA_INPUT_ into a camelcased input equivalent.

For example with an env of EXTRA_INPUT_CHECK_IT_OUT=hello, this will result in an input of checkItOut=hello.

The action produces an output called matrix-json which can passed directly to downstream actions by running fromJSON() on it.

Usage

- id: extra-inputs
  uses: chainguard-dev/actions/matrix-extra-inputs@main
  with:
    matrix-json: ${{ toJSON(matrix) }}
  env:
    EXTRA_INPUT_CHECK_IT_OUT: hello
- run: |
    echo '${{ steps.extra-inputs.outputs.matrix-json }}' > inputs.json
    echo "checkItOut value: $(jq -r .checkItOut inputs.json)"
