scrapligo -- scrap(e c)li (but in go!) -- is a Go library focused on connecting to devices, specifically network devices (routers/switches/firewalls/etc.) via SSH and NETCONF.

NOTE this is a work in progress, use with caution!

Key Features:

• Easy: It's easy to get going with scrapligo -- if you are familiar with go and/or scrapli you are already most of the way there! Check out the examples linked above to get started!
• Fast: Do you like to go fast? Of course you do! All of scrapli is built with speed in mind, but this port of scrapli to go is of course even faster than its python sibling!
• But wait, there's more!: Have NETCONF devices in your environment, but love the speed and simplicity of scrapli? You're in luck! NETCONF support is built right into scrapligo!

Running the Examples

You need Go 1.16+ installed. Clone the repo and go run any of the examples in the examples folder.
