Hi Alia, authors,
OK, so the tooling is still a bit rough and ready, but I've tweaked it a
bit and run it on the VRRP module.
The tooling itself:
(1) Alpha/beta level quality, generally it seems to work OK, but the
results need to be carefully checked (e.g. by diffing the old and new
modules to see what has changed).
(2) Is just a fork of pyang with some extra modules (it is sync'ed with
Martin's latest pyang github repository today).
(3) Current code is available at: https://github.com/rgwilton/pyang
- Feel free to clone, extend, pull requests, etc.
(4) How does it work?:
- It looks through the parallel config/state trees finding nodes with
the same names on equivalent paths.
- It that match then it checks description and reference and merges them
together. If it merges it flags it with a "FIX ME" comment.
- It also tries to handle augmentations and groupings, by heuristically
checking for "-state" in the grouping name.
(5) Stuff that is known not to work:
- It should, but currently doesn't, validate that the same type is used
between the config and state leaves!
- I've not tried it with submodules, I'm not sure how it will fare.
(6) Generically it is used like this (from the directory that contains
the split YANG module):
- clone the github repository above, and ensure pyang's normal
dependencies are available.
- run these commands:
cd <pyang directory>
source env.sh
cd <yang module directory>
"pyang -f yang --max-line-length 69 --ietf-split-to-combined-tree
--remove-state-nodes <src.yang> > <tgt.yang>"
(7) Actual example steps on VRRP (draft-ietf-rtgwg-yang-vrrp-04), module
extracted by rcfstrip:
# Generate a 'clean' tree for more informative diff (or else many
whitespace changes are reported).
pyang -f yang --ietf --max-line-length 69 [email protected] >
[email protected]
pyang -f yang --ietf-split-to-combined-tree --remove-state-nodes
--max-line-length 69 [email protected] >
[email protected]
diff [email protected] [email protected] >
vrrp-nmda.diff
# Checking the tree output is also sensible.
pyang -f tree [email protected] > [email protected]
pyang -f tree --ietf [email protected] >
[email protected]
diff [email protected] [email protected] >
vrrp-nmda-tree.diff
The new VRRP YANG module, New tree output, model diff, and tree diff are
all attached.
Requires manual fixing:
- revision date/history
- a few "FIX ME" comments to merge config/state description strings.
- check that leaf types match for any config/state nodes on equivalent
paths where the state leaf has been removed.
Thanks,
Rob

As is customary, I have done my AD review of
draft-ietf-rtgwg-yang-vrrp-04. First, I would like to thank the
authors, Xufeng, Athanasios, Ravi, Acee,and Mingui, as well as the WG
for their work on this draft. It is clear and well-written.
My one issue is that it does not conform to the NMDA guidelines. I
know that the transformation can be done largely programmatically -
and Acee & Xufeng are quite familiar with the details. I've also cc'd
Rob Wilton who has some tooling to potentially help.
From the shepherd's report, I understand that there is an
implementation. That implies that the existing model should be in the
appendix.
I would be delighted to forward this draft to IETF Last Call (and my
apologies for the long delay in review) after it has been updated.
Thanks,
Alia
