This is probably useful, but I don't think it belongs in the depend output, since depend is designed to generate Makefile dependency rules.

[miott]

This is probably useful, but I don't think it belongs in the depend output, since depend is designed to generate Makefile dependency rules.

Makefile dependency rules point to filenames. It is within the specification that a yang file can be named using its latest revision number as shown in the example above (openconfig-network-instance@2021-01-25.yang). I can make a change to the output so the revision number can be added to the Makefile rule.

[mbj4668]

Good idea!

[miott7]

Tested all output options: --depend-recurse --depend-target ALL --depend-extension .txt --depend-include-path --depend-include-revision.

Note: Option --depend-include-path will ignore --depend-include-revision just like --depend-extension does because in that case the actual file path and file names are used as prerequisites.

Command: pyang -f depend --depend-recurse --depend-target ALL --depend-include-revision -o ~/pyang/depend-target-rev.txt openconfig-network-instance@2021-01-25.yang

Result: ALL : ietf-yang-types@2013-07-15 ietf-inet-types@2013-07-15 openconfig-network-instance-types@2021-05-21 openconfig-policy-types@2016-05-12 openconfig-routing-policy@2016-05-12 openconfig-local-routing@2016-05-11 openconfig-interfaces@2018-01-05 openconfig-extensions@2020-06-16 openconfig-network-instance-l3@2018-11-21 openconfig-types@2019-04-16 openconfig-bgp@2016-06-21 openconfig-mpls@2016-12-15 openconfig-vlan@2016-05-26 openconfig-ospfv2@2021-03-17 openconfig-policy-forwarding@2021-05-19 openconfig-segment-routing@2017-01-12 openconfig-isis@2017-01-13 openconfig-aft@2017-01-13 openconfig-pim@2021-04-21 openconfig-igmp@2019-07-09 openconfig-evpn@2020-11-24 openconfig-network-instance-l2@2021-01-25 ietf-interfaces@2018-02-20 openconfig-yang-types@2018-11-21 openconfig-bgp-common@2016-06-21 openconfig-bgp-common-multiprotocol@2016-06-21 openconfig-bgp-common-structure@2016-06-21 openconfig-bgp-peer-group@2016-06-21 openconfig-bgp-neighbor@2016-06-21 openconfig-bgp-global@2016-06-21 openconfig-bgp-types@2016-06-21 openconfig-mpls-types@2016-12-15 openconfig-mpls-rsvp@2016-12-15 openconfig-mpls-ldp@2016-12-15 openconfig-mpls-te@2016-12-15 openconfig-mpls-igp@2016-12-15 openconfig-mpls-static@2016-12-15 openconfig-mpls-sr@2016-12-15 openconfig-vlan-types@2016-05-26 openconfig-if-ethernet@2020-05-06 openconfig-if-aggregate@2018-01-05 iana-if-type@2019-02-08 openconfig-ospfv2-global@2019-11-28 openconfig-ospfv2-area@2019-11-28 openconfig-ospfv2-area-interface@2021-03-17 openconfig-ospfv2-lsdb@2019-11-28 openconfig-ospfv2-common@2019-11-28 openconfig-ospf-types@2018-11-21 openconfig-bfd@2021-03-17 openconfig-if-types@2018-11-21 openconfig-inet-types@2017-08-24 openconfig-pf-forwarding-policies@2021-05-19 openconfig-pf-path-groups@2021-05-19 openconfig-pf-interfaces@2021-05-19 openconfig-packet-match@2017-05-26 openconfig-packet-match-types@2017-05-26 openconfig-isis-types@2017-01-13 openconfig-isis-lsp@2017-01-13 openconfig-isis-routing@2017-01-13 openconfig-isis-lsdb-types@2017-01-13 openconfig-aft-types@2017-01-13 openconfig-pim-types@2018-11-21 openconfig-acl@2017-05-26 openconfig-igmp-types@2018-11-21 openconfig-evpn-types@2020-10-08
