# Using the native parser

# -------------
# templates/nxos_show_interface.yaml
# - example: Ethernet1/1 is up
#   getval: '(?P<name>\S+) is (?P<oper_state>\S+)'
#   result:
#     "{{ name }}":
#         name: "{{ name }}"
#         state:
#         operating: "{{ oper_state }}"
#   shared: True
#
# - example: admin state is up, Dedicated Interface
#   getval: 'admin state is (?P<admin_state>\S+)'
#   result:
#     "{{ name }}":
#         name: "{{ name }}"
#         state:
#         admin: "{{ admin_state }}"
#
# - example: "  Hardware: Ethernet, address: 0000.5E00.5301 (bia 0000.5E00.5301)"
#   getval: '\s+Hardware: (?P<hardware>.*), address: (?P<mac>\S+)'
#   result:
#     "{{ name }}":
#         hardware: "{{ hardware }}"
#         mac_address: "{{ mac }}"

# Using the ntc_templates parser

# -------------
# The ntc_templates use 'vendor_platform' for the file name
# it will be derived from ansible_network_os if not provided
# example cisco.ios.ios => cisco_ios

- name: Run command and parse with ntc_templates
  ansible.utils.cli_parse:
    command: "show interface"

# Using the pyats parser

# -------------
# The pyats parser uses 'os' to locate the appropriate parser
# it will be derived from ansible_network_os if not provided
# in the case of pyats: cisco.ios.ios => iosxe

- name: Run command and parse with pyats
  ansible.utils.cli_parse:

# Value PLATFORM (\w+)
#
# Start
#   ^\s+(NXOS: version|system:\s+version)\s+${OS}\s*$$
#   ^\s+(NXOS|kickstart)\s+image\s+file\s+is:\s+${BOOT_IMAGE}\s*$$
