Usage Notes
output
By default, stdout and stderr both print to the console. The foreground color (fg) and background color (bg) parameters are optional.
colors are automatically suppressed if the output buffer is not a TTY
input
The optional mode parameter accepts the following values:
- 'plain', plain input (no readline cursor, no history)
- 'quiet', like plain mode, but without feedback
- 'secret', special mode for password input
null(default), with readline and input history
