Garnish - A Terminal UI Framework for SSH based applications
Garnish is a Terminal UI Framework based on the Ratatouille view architecture, but adapted for Erlang’s ssh framework.
Sitting on :ssh - as an ssh_cli server channel - allows secure remote access to the Elixir app. The view architecture, shamelessly copied from Ratatouille, enables simple TUI apps to be built, typically for operator/admin experiences (which is the use case I have). Under the covers, the logical render of the view is translated into terminal escape sequences. This is also removes the need for the ex_termbox NIF that Ratatouille required.
I did diverge a little the app model, which I made a little more idiomatic from an OTP perspective, but the view modules and the render/1 callback are exactly as they were in Ratatouille.
This is the initial early release, expect some rough edges. EDIT: Notably, it only supports xterm-256color right now and is untested on other terminals, but it will pretty easy to add others, which I plan to do.

This is so cool! A modern foundation of text BBS and MUD, anyone? I had similar idea awhile back but got intimidated by the amount of work it would require. Thanks again for the library; I will use it in a future project.
Have you connected with the author of Ratatouille? It would make a lot of sense if you can work together to extract out the view layer as a separate library.
Another idea is to fuse the Mosh server with Garnish, so client can connect with mosh client instead of ssh to enjoy roaming, auto-reconnecting, and latency optimization. It will be a lot of work but the benefit is huge.

I’m using this library on two different projects at the moment, and wanted to share how helpful it’s been. Exposing a TUI dashboard over SSH is tremendously valuable, and I look forward to future developments!

Curious to see this project in action, but the Asciinema recording on the GitHub project page seems to have expired.

Oh I didn’t even realise that was a thing, thx for letting me know

Garnish is exactly the ratatouille view framework with some module renaming. I spoke to the author and he was happy to see the code reused.
The rendering code is more expensive than I’d like but it’s fine for a few users which is my use-case, so I’m unlikely to invest too much time chasing this down.
