Prompts

Input

Ask a simple question requiring the user to type any string. It returns always a String

import FortyTwo (input)

main :: IO String
main = input "What's your name?"

inputWithDefault will let you define a fallback answer if no answer will be provided

import FortyTwo (inputWithDefault)

main :: IO String
main = inputWithDefault "What's your name?" "Undefined"

Confirm

Confirm prompt returning a boolean either True or False. If no answer will be provided it will return False

import FortyTwo (confirm)

main :: IO Bool
main = confirm "Are you old enough to see this?"

confirmWithDefault will let you define a fallback answer if no answer will be provided

import FortyTwo (confirmWithDefault)

main :: IO Bool
main = confirmWithDefault "Are you old enough to see this?" True

Password

Password prompt hiding the values typed by the user. It will always return a String

import FortyTwo (password)

main :: IO String
main = password "What's your secret password?"

Select

Select prompt letting users decide between one of many possible answers. It will always return a String

import FortyTwo (select)

main :: IO String
main = select
         "What's your favourite color?"
         ["Red", "Yellow", "Blue"]

selectWithDefault will let you define a fallback answer if no answer will be provided

import FortyTwo (selectWithDefault)

main :: IO String
main = selectWithDefault
         "What's your favourite color?"
         ["Red", "Yellow", "Blue"]
         "Red"

Multiselect

Multiselect prompt letting users decide between multiple possible choices. It will always return a collection [String]

import FortyTwo (multiselect)

main :: IO [String]
main = multiselect
         "What are your favourite films?"
         ["Titanic", "Matrix", "The Gladiator"]

multiselectWithDefault will let you define a fallback answer if no answer will be provided

import FortyTwo (multiselectWithDefault)

main :: IO [String]
main = multiselectWithDefault
         "What are your favourite films?"
         ["Titanic", "Matrix", "The Gladiator"]
         ["The Gladiator"]
