Research direction

The panic occurs at actions.go line 121 in the MultiChoice method. Examine the method to understand how it handles the slice of choices and the index. The test code shows a simple usage with four options; check for off-by-one errors or incorrect bounds checking. Run the provided test to reproduce the panic, then look at the surrounding code to see what assumptions are being violated.

Written by the indexing model from the issue text.

Description

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
