Polyfill missing if of actions/runner

Usage:

  • You have to surround the if condition with ${{...}} otherwise it won't work.
  • The pipe symbol ( | ) after step: is required, because inputs have to be strings.
  • Expression syntax will even work on places github wouldn't allow (step property)
  • Pre steps aren't executed, because they won't work with local actions.
- uses: ChristopherHX/conditional@a675ed4b9377f0f6e385f1c992f4a53de60ec521
  with:
    if: ${{steps.cacheaction.outputs.cache-hit != 'true'}}
    step: |
      uses: actions/setup-node@v3
      with:
        node-version: ${{inputs.nodever}}

Full example

How does it work?

This small composite action create a temporary child composite action in ./.github/conditional/tmp/, based on the evaluated condition and your provided step, therefore you can skip a uses directive. If the condition evaluates to false, it executes an empty action instead. The usage of - uses: actions/github-script@v6 allows this action to work on linux / windows / mac without the need for bash or downloading any other shell.
