Usage

Here's a simple example of how to use DynamicCursesInput:

require "curses"
require "dynamic_curses_input"

begin
  Curses.init_screen
  Curses.start_color
  Curses.addstr("You should be able to use the left and right arrow keys to switch between characters in the line, and selectively edit them.\n")
  Curses.addstr("Enter your name: ")
  name = DCI.catch_input(true)
  Curses.addstr("\nYou entered: #{name}")
  Curses.getch

  # Log the output
  logger.info("Name entered: #{name}")
ensure
  Curses.close_screen
