Prompt interface overview

The following Prompts are supported by the Golang SDK:

  • Checkbox
  • Confirm
  • Datetime
  • Editor
  • Input
  • List
  • Number
  • Password
  • Secret

To create a prompt in your Op, you need to create a new Prompt object (whose methods are the above listed supported Prompts):

func NewPrompt() *Prompt

Alternatively, the Prompt object is included in the Client object:

client := NewClient()
client.Prompt.Checkbox(...)

func (*Prompt) Checkbox

func (*Prompt) Checkbox(name, msg string, choices []string, options ...CheckboxOption) ([]string, error)

Checkbox presents a list of options to the user, who can select multiple items in the interface (i.e. terminal or Slack).

choices is the list of string options that can be selected.

Example:

p := ctoai.NewPrompt()
resp, err := p.PromptCheckbox("tools", "Which interpreters would you like to have included in your OS image?", []string{"Lua", "Node.js", "Perl", "Python 2", "Python 3", "Raku", "Ruby"}, OptCheckboxDefaultValues([]string{"Lua"}), OptCheckboxFlag("C")) // user selects Luaif err != nil {
    panic(err)
}

fmt.Println(resp)

Output:

Lua

Type:

type CheckboxOption func(*daemon.CheckboxPromptBody)

func OptCheckboxDefaultIndex

func OptCheckboxDefaultIndex(defaultIndexes []int) CheckboxOption

func OptCheckboxDefaultValues

    panic(err)
}

fmt.Println(resp)

if err != nil {
    panic(err)
}

fmt.Println(resp)

Output:

[the output will equal time.Now() in 2006-01-02 15:04:05 format]

Type:

type DatetimeOption func(*daemon.DatetimePromptBody)

func OptDatetimeDefault

func OptDatetimeDefault(defaultValue time.Time) DatetimeOption

func OptDatetimeVariant

func OptDatetimeVariant(variant string) DatetimeOption
