A terminal emulator (such as xterm, tmux, or emacs) is responsible for displaying a pseudoterminal in a different context (such as an x server, another terminal, or an emacs buffer respectively). Terminals are divided into three types: virtual terminals (on boot or as presented by [C-]A-F<N>), ‘true’ terminals (exposed on serial ports), and pseudoterminals (controlled by other programs). Essentially, you have a virtual terminal running X running Xterm which controls a pseudoterminal with tmux attached controlling another pseudoterminal.

Login shells are a special flag set when launching shells, sometimes. They typically read different settings (e.g. Bash reads ~/.bash_profile instead of ~/.bashrc). Most shells will launch as a login shell if their command name (argv[0]) begins with a hyphen; Bash also allows explicit bash -l to run a login shell.

Note that Tuwunel maintainers are banned from the Matrix foundation and have openly threatened Continuwuity developers.

overall we need something to text

pretty much Matrix’s entire point

(plus send files)

also implemented in pretty much every server and client; I think even Element can send files

call

look into e.g. #matrixrtc:continuwuity.org — sable requires a setting to show the call button in non-DM rooms

video/screen share

unfortunately this is the only thing I’m not confident is supported

bonus for emojis, stickers

should be available with any im.ponies-compatible client such as sable

Not telemetry? Continuwuity just uses it to post release announcements to the admin room; I think there’s a way to disable it if you prefer.

Thanks; didn’t have it saved like that

There aren’t any unhandled errors! There aren’t any unvalidated inputs!

or creatures :3
