Hi  
I want to develop a command line environment using ruby, it can  
- edit the command line online, like vi mode or emacs mode  
in bash  
- support command history and history searching  
- the command is not the real shell command. It is just a  
string , when hit enter, this string will pass to another class to  
interpret.

```
    Is there any package to use?
   Or any other advice?
```

You could also pick up cmd [0], which is no longer in development but is  
fairly easily extended and might well suffice for simple cases.
