# 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](https://github.com/manifoldco/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](https://github.com/spf13/cobra),
|
|
[urfave/cli](https://github.com/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](https://godoc.org/github.com/manifoldco/promptui).

## Basic Usage
|
|
|
|
### Prompt
|
|
|
|
```go
|
|
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
|
|
|
|
```go
|
|
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)
|
|
}
|
