promptui

Interactive prompt for command-line applications.

We built Promptui because we wanted to make it easy and fun to explore cloud services with manifold cli.

Overview

Promptui is a library providing a simple interface to create command-line prompts for go. It can be easily integrated into spf13/cobra, urfave/cli or any cli go application.

Promptui has two main input modes:

• Prompt provides a single line for user input. Prompt supports optional live validation, confirmation and masking the input.

• Select provides a list of options to choose from. Select supports pagination, search, detailed view and custom templates.

For a full list of options check GoDoc.

Basic Usage

Prompt

package main
import (
"errors"
"fmt"
"strconv"
"github.com/manifoldco/promptui"

)
func main() {
validate := func(input string) error {
_, err := strconv.ParseFloat(input, 64)
if err != nil {
return errors.New("Invalid number")
}
return nil
}
prompt := promptui.Prompt{
	Label:    "Number",
	Validate: validate,
}

result, err := prompt.Run()

if err != nil {
	fmt.Printf("Prompt failed %v\n", err)
	return
}

fmt.Printf("You choose %q\n", result)

}

Select

package main
import (
"fmt"
"github.com/manifoldco/promptui"

)
func main() {
prompt := promptui.Select{
Label: "Select Day",
Items: []string{"Monday", "Tuesday", "Wednesday", "Thursday", "Friday",
"Saturday", "Sunday"},
}
_, result, err := prompt.Run()

if err != nil {
	fmt.Printf("Prompt failed %v\n", err)
	return
}

fmt.Printf("You choose %q\n", result)

}
