Proof-of-concept shell interface outside a terminal.

This works with bash and the Go sh/interp package.

Build with:

go generate
go build

Run:

./web_shell
# Or, to get rid of the controlling terminal:
# (requires using `kill` to exit)
setsid ./web_shell

Clean:

rm web_shell lib/inject_tcsetpgrp.so

Shift-Enter to enter a new line.
Ctrl-C to interrupt a running command.
Double-click to collapse a command's output.

It's horrible in many ways. Most notably, the shell interpreter instance is global.
