It seemed like it could be fun and educational, so I started making a 9-like terminal for OS X using the native text widget:

But there are 2 things I’ve had trouble figuring out on my own:

1) Why do programs like ‘python’ show a prompt in 9term but not in my terminal?

2) Why does bash write your command to stdout? Why doesn’t rc? I use bash, so I made it erase the command you typed when you press enter, but that appears to be the wrong thing to do with rc.

There’s other stuff in BUGS.md but I feel more confident about those things. :)
