module: ovirt_network_facts
short_description: Retrieve information about one or more oVirt/RHV networks
author: "Ondra Machacek (@machacekondra)"
deprecated:
    removed_in: 3.0.0  # was Ansible 2.13
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt.ovirt.ovirt_network_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV networks."
notes:
    - "This module returns a variable C(ovirt_networks), which
       contains a list of networks. You need to register the result with
       the I(register) keyword to use it."
options:
    pattern:
      description:
        - "Search term which is accepted by oVirt/RHV search backend."
        - "For example to search network starting with string vlan1 use: name=vlan1*"
extends_documentation_fragment:
- community.general.ovirt_facts

'''


EXAMPLES = '''
# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

- name: Gather information about all networks which names start with vlan1
  ovirt_network_info:
    pattern: name=vlan1*
  register: result

- name: Print gathered information
  ansible.builtin.debug:
    msg: "{{ result.ovirt_networks }}"
'''


RETURN = '''
ovirt_networks:
    description: "List of dictionaries describing the networks. Network attributes are mapped to dictionary keys,
                  all networks attributes can be found at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/network."
    returned: On success.
