Multiple Choice #82

Open ryangurn opened 6 years ago

ryangurn commented 6 years ago

When attempting to use the mutiple choice option, I get the following panic. Please let me know what other information would help assist in getting this fixed moving forward, I will also look into the code to see if there is anything I can do to fix it and submit a PR if I figure something out.

func Test(c *ishell.Context) {
    choice := c.MultiChoice([]string{
        "Golangers",
        "Go programmers",
        "Gophers",
        "Goers",
    }, "What are Go programmers called ?")
    if choice == 2 {
        c.Println("You got it!")
    } else {
        c.Println("Sorry, you're wrong.")
    }
}
panic: runtime error: index out of range

I have the same problem and surprised that this issue goes back to 2018. I wonder whether the project is still maintained or abandoned...
