module: package_facts
short_description: Package information as facts
description:
  - Return information about installed packages as facts.
options:
  manager:
    description:
      - The package manager used by the system so we can query the package information.
      - Since 2.8 this is a list and can support multiple package managers per system.
      - The 'portage' and 'pkg' options were added in version 2.8.
      - The 'apk' option was added in version 2.11.
      - The 'pkg_info' option was added in version 2.13.
    default: ['auto']
    choices: ['auto', 'rpm', 'apt', 'portage', 'pkg', 'pacman', 'apk', 'pkg_info']
    type: list
    elements: str
  strategy:
    description:
      - This option controls how the module queries the package managers on the system.
        C(first) means it will return only information for the first supported package manager available.
        C(all) will return information for all supported and available package managers on the system.
    choices: ['first', 'all']
    default: 'first'
    type: str
    version_added: "2.8"
version_added: "2.5"
requirements:
    - For 'portage' support it requires the C(qlist) utility, which is part of 'app-portage/portage-utils'.
    - For Debian-based systems C(python-apt) package must be installed on targeted hosts.
    - For SUSE-based systems C(python3-rpm) package must be installed on targeted hosts.
      This package is required because SUSE does not include RPM Python bindings by default.
