PromptConfig
Fields pPrompt :: String pBasicCharacters :: [Char] pAdvancedCharacters :: [Char] only shown on help pDefault :: Maybe Char pHelp :: [Char]

promptYorn :: String -> IO Bool Source #

Prompt the user for a yes or no

promptChar :: PromptConfig -> IO Char Source #

Prompt the user for a character, among a list of possible ones. Always returns a lowercase character. This is because the default character (ie, the character shown in uppercase, that is automatically selected when the user presses the space bar) is shown as uppercase, hence users may want to enter it as uppercase.
