Re: [netmod] Fwd: Re: How to grep through a YANG? With grepyang

Hi Ariel,

This looks like an interesting/useful tool.

Have you considered hooking into pyang as a pyang extension?

pyang is one of the defacto standard tools that folks interacting with 
yang often use.  If your aim to get widespread usage of your tool making 
it a pyang extension may be one way to achieve that. E.g. this would 
then allow your tool to generate tree output for selected yang 
subtree(s) nodes that you find, or other nice things.

Thanks,
Rob
