inputs:
  override-ref:
    description: |
      The commit or git ref to checkout and build for. When running this action on github.com,
      the default value is sufficient.
    required: true
    default: ${{ github.server_url == 'https://github.com' && github.sha || 'main' }}
  override-repository:
    description: |
      The GitHub repository to clone RustPython from. When running this action on github.com,
      the default value is sufficient. Useful for Forks.
    required: true
    default: ${{ github.server_url == 'https://github.com' && github.repository || 'RustPython/RustPython' }}
  override-rustpython-path:
    description: |
      override value for path to the Python Lib. The default is to use the value of the environment
      variable 'RUSTPYTHONPATH'. Most users will find the default 'Lib' sufficient.
    required: true
    default: ${{ github.server_url == 'https://github.com' && github.repository || 'Lib' }}
  override-path:
    description: |
      Path to setup. When running this action on github.com, the default value
      is sufficient. MUST be a path to a directory named 'rustpython'.
    required: true
    default: ${{ github.server_url == 'https://github.com' && github.workspace || 'rustpython' }}
  github-token:
    description: |
      The token used to authenticate when fetching RustPython commits from
      https://github.com/RustPython/RustPython.git. When running this action on github.com,
      the default value is sufficient. When running on GHES, you can pass a personal access
      token for github.com if you are experiencing rate limiting.
    default: ${{ github.server_url == 'https://github.com' && github.token || '' }}
