simple-prompt

A simple commandline text prompt library for user input.

The SimplePrompt module provides:

  • prompt: returns a string
  • promptNonEmpty prompts for non-empty string
  • promptInitial with pre-filled initial input
  • promptPassword prompts for password
  • promptChar prompts for a character
  • promptKeyPress waits for a key press
  • promptEnter waits for Enter key
  • yesNo expects y/n answer
  • yesNoDefault [y/N] or [Y/n]

It uses haskeline to read the input.

The SimplePrompt.Internal module provides lower-level access to functional haskeline InputT monad transformer-based prompt functions:

  • runPrompt, getPrompt*
  • untilInput, mapInput, clearedInput, nonEmptyInput.
