Implement Generic Command Modeling

See #95

2021 05 27 Edit

I'm modifying this issue to encompass a discussed and highly-requested ability to implement arbitrary commands that are in no way linked to address-family or VRFs, and only optionally use built-in validation.

+1 for that feature 👍
Would it be possible to allow more commands definitions/customization - in addition to those 5 already implemented (bgp, ping traceroute)?
Something like raw output from defined query.

Hey @brevius - we were discussing this on Telegram the other day, and I agree that we need to genericize the commands so that we end up with built-in commands that are fully validated (and parsed for consumption in a table, where possible), with the ability to add arbitrary commands as well. I've been thinking about various ways to handle this and I think I have some good ideas. I have a lot going on at work in the next couple of weeks, but I'll try to get it done as quickly as possible.

These are cisco nxos commands but these are my top 3..

bgp_summary: "show ip bgp summary"
bgp_peer_received: "show bgp ipv4 unicast neighbor {target} received-routes"
bgp_peer_advertised: "show bgp ipv4 unicast neighbor {target} advertised-routes"

[brevius]

Something usefull for JunOS:
bgp_peer_discarded: "show route receive-protocol bgp {target} table {vrf}.inet.0 hidden"

What about this issue? Will it be done?

@streamthing The vast majority of this is done in the v2.0.0 branch. Unfortunately, I've had a number of personal and professional obstacles over the past several months that's prevented me from working on much of anything development-related, hyperglass included. I'm hoping to get back to it very soon, though.

The v2.0.0 branch should be usable-ish, you'd just have to really study the codebase to get it working with custom generic commands, as one of the primary things left to do prior to release is write documentation.

@thatmattlove No problem, I'll wait for v2.0.0.
Great work, it's works very well! <3
