local-echo VS xterm.js

I just want to say thanks, I have been experimenting with using xterm.js to connect to terminal API in jupyter notebooks and it was worked really well, plug and play (even editors like vim were working without any extra effort).

Before that I was experimenting with using it as a custom shell for running commands inside a web application. In that use case it was a bit more challenging because I had never written to an actual tty before (ansi escape codes for coloring log files has been about the limit of my experience). For that use case I just really needed to send and receive text. I ended up using this library [ https://github.com/wavesoft/local-echo ] to smooth that process out until I could learn about how to do things properly.

Are any suggestions on 1. where to learn about how ttys work to things the right way, or 2. suggested libraries like local-echo that can wrap over some of the trickier bits of just getting text on the screen?

Thanks again for maintaining such a great & useful library!

I'm on the VS Code team and maintain xterm.js which is what Hyper's frontend is based on. There are actually multiple developments happening in this area.

First, there's a contribution from the author of DomTerm which adds grapheme cluster support to xterm.js, which will correctly merge and size things like emoji that are called out in the post. This is currently based on Unicode 15. See https://github.com/xtermjs/xterm.js/pull/4519

Second, while Windows Terminal does seem to work with emoji sometimes, it doesn't all the time. I'm not 100% sure, but I think it may only work on Windows ptys, not in WSL for example. Last time I spoke with the team they said they're working on a rewrite which could lead to proper emoji support.

Ooh, I lack the time to play with this, but I think someone could compile the lib to WebAssembly and tie it in to https://xtermjs.org/

Then you could have a web page with static DOM elements that do this effect!

xterm is a JavaScript library that provides a web-based terminal emulator with ANSI escape sequences, Unicode characters, and other features. It is easy to use and customize, making it a popular choice for adding a terminal interface to web applications.

Setting scrollback to infinite? #518

The simpler path would be starting the WASM port using Emacs character mode running alongside an in-browser terminal emulator such as XTerm.js.
