Charm – tools to make the command line glamorous
TUIs over ssh/telnet can be a lot of fun. Especially in cases where multiple people can interact with each other on the server. It simplifies the programming model as you only have one state on the backend that you render to multiple connections. Syncing up everyone becomes trivial. You can also use some React concepts, like rendering a virtual TUI and sending just the right set of minimal escape sequences back to the user to bring their display up to date.
A few months ago I implemented a telnet chat server[0] for fun and it was surprisingly easy to do so. Even by using a wasm vm that I was still working on at the same time.

Launch HN: Lunatic (YC W21) – An Erlang Inspired WebAssembly Platform
We are investing a lot of effort into making Lunatic feel native to the particular language and ecosystem. If you look at the Rust chat server we built in Lunatic (https://github.com/lunatic-solutions/chat), it fully integrates with cargo. You just run your typical “cargo run” command, it will compile the app to wasm and use lunatic to run it. If you want to run your test, you can just do “cargo test”.
wasm-bindgen is necessary only because it’s really hard right now to merge the wasm world and the JS one in the browser. We have the advantage here of staying out of the browser.

How I built a telnet chat server in 2021 with WebAssembly
It took me around a week to build it with Rust + Lunatic and you can check out the code here. If you would like to try it out you can connect to it with:

The Stakker actor runtime: Beyond "Go++"
Recently I implemented a command line chat server in Rust using an actor framework. I model each TCP connection as an actor.

I built a telnet chat server with WebAssembly
Hi HN,
I'm working on an Erlang inspired WebAssembly runtime for the backend[0]. Recently I added TCP support and was looking for apps I could build with it. I ended up building a telnet line chat app. It was a great dogfooding experience and has a nice retro feel to it.
You can access the US server with:
> telnet lunatic.chat
or the EU one with:
> telnet eu.lunatic.chat
Pick the one closer to you, as all the rendering is done on the backend and lower latency will mean better UX.
The server is open source[1] and written in Rust. The Rust code is then compiled to WebAssembly and runs on top of Lunatic. Each connection runs in a separate (lightweight) process, has it's own state and sends just a diff of esc-sequences back to the terminal to bring it up to date with the current render buffer. Everything is deployed to an ARM Linux box.

Is it too early to use Zig for CLI tooling ideas?
I think zig might actually be the best language for CLI if it had a charm ( https://github.com/charmbracelet/charm ) like eco system
