Discussion on: Shareable CLI demo?

[Ben Lovy]

The WASM thing is absolutely overkill, with you there 100%.

Are the prompts for 'configuration' only?

Not really - the prompts are the main event. It builds a branching tree of prompts from the input file provided, and can refer to previously received responses.

The "real" option would be to ditch text prompts and build graphical widgets, which sounds fun, too, but not a one-day thing.

This definitely sounds like it fits. I've never mucked about with TCP before but I don't think there's anything in my way conceptually, at least.

I've just scrapped around with this in Go - I'm sure you can convert to Rust with ease - using cowsay as the target command line app:

package main

import (
    "fmt"
    "net"
    "os"
    "os/exec"
)

func main() {
    listen, err := net.Listen("tcp", "127.0.0.1:6000")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    conn, err := listen.Accept()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    cmd := exec.Command("cowsay")
    cmd.Stdin = conn
    cmd.Stdout = conn
    cmd.Start()
    cmd.Wait()
}

Above and beyond, David, thanks for the sample!

That might be exactly the ticket - no real need to translate to Rust, I might just start with your Go template if you don't mind, that looks like less friction.
