Hyper-Interactive

Hyper-Interaction is a very small tiny library to help making a command line app become interactive. It allowes user to fill in qustionaire, making configuration or just a simple information input.

go get -u github.com/hyperjumptech/hyper-interactive

Simple text input

import (
	"fmt"
	interactive "github.com/hyperjumptech/hyper-interactive"
)

...
name := interactive.Ask("Whats your name ?", "Bruce Wayne", false)
fmt.Println("Hi " + name)
...

The command line will look like

$ interact
Whats your name ? [default "Bruce Wayne"] : Ferdinand
Hi Ferdinand

Default Answer

If you see [default __], simply hit enter will use the default value as your answer.

Confirming your Answer

All question type have a confirmation flag in their argument. For example

// the last argument is a confirmation flag
name := interactive.Ask("Whats your name ?", "Bruce Wayne", true) 
fmt.Println("Hi " + name)

This will result

$ interact
Whats your name ? [default "Bruce Wayne"] : Ferdinand
"Ferdinand", are you sure? (y/n/Y/N) [default : Y] ? Y
Hi Ferdinand

You will get result

The logic in all of those ask function will make sure the user fill in the correct answer.

• User are ensured to choose valid option
• User are ensured to specify valid number
• User are ensured to specify valid time format
• etc

Asking for Options

options := []string {
    "One","Two","Three",
    "Four","Five","Six",
    "Seven","Eight","Nine",
    "Ten",
}
choosen := interactive.Select("Please choose", options, 1,1, true)
fmt.Printf("You choose number %d\n", choosen)
