or operation

Composite operation that takes a list of operations as parameter.

When called during omni up, it will execute operations in the list until one of them is available and succeeds. If none of the operations are available, the or operation will be considered unavailable. If none of the available operations succeed, the or operation will fail.

When called during omni down, it will execute all operations in the list.

Examples

  # Installs gawk using either homebrew or nix, whichever is available,
  # and if both are available will use homebrew in priority
  - or:
    - homebrew:
        install:
        - gawk
    - nix:
      - gawk
