This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

[maintain] [Publish]

Byline simplifies writing interactive command-line applications by building upon ansi-terminal and haskeline. This makes it possible to print messages and prompts that include terminal escape sequences (such as setting text colors) that are automatically disabled when standard input is a file. It also means that Byline works on both POSIX-compatible systems and on Windows.

The primary features of Byline include printing messages, prompting for input, and generating custom menus. It was inspired by the highline Ruby library and the terminal library by Craig Roche.

Example

example :: MonadByline m => m Text
example = do
  sayLn ("Hey, I like " <> ("Haskell" <> fg magenta) <> "!")

  let question =
        "What's "
          <> ("your" <> bold)
          <> " favorite "
          <> ("language" <> fg green <> underline)
          <> "? "

  askLn question (Just "Haskell")
