Hi ultra config,

Can you please help me with this?

I want the pattern in leaf to take only 2 strings as input.
The strings are
["IPv4"]
["IPv6"]
Along with the square brackets and quotations. If the address mentioned is ipv4 then they also should mention that they mentioned ipv4 as ["IPv4"] and for ipv6 also the same.
So the pattern for this given is
'((["IPv4"] | ["IPv6"]))' ;
But this didn't work
Also tried
'(([\"IPv4\"] | [\"IPv6\"]))' ; this one is working but it is also taking all kinds of strings which is not the requirement so can you help in getting only ["IPv4"] and ["IPv6"]


Thank you

Super clear.

Excellent tutorial!
Thank you for putting this together.

Thanks a lot for putting this together!

How yang revisions are supported by yang libraries. AFAIK it is done by maintaining different file for each revision per module such as <module>@<revision-date>.yang files. Any other information I can read about the same?

Thanks, can you please share the link of the written blog you are using for explanation

This makes easy to understand, Thanks mate

Thank you, well explained !

Ultra Config, how can I validate a yang file in windows or save as file.yang? Or which editor can recognize a yang file? Thanks

Thank you for a great overview. FYI, I did encounter few problems for which I've noted the solutions below.
1. One needs to use switch `-x` to ignore yang version error
2. When using python virtual environment, export PYANG_XSLT_DIR=env/share/yang/xslt and export PYANG_RNG_LIBDIR=env/share/yang/schema
