#terminal-menu-disabler

A package that extends terminal-menu, making it capable of enabling/disabling menu items on the fly.

#example

var menu = require('terminal-menu')({ width: 30, x: 2, y: 2 });
var disabler = require('terminal-menu-disabler')(menu, {
  // uncomment following line to make forground
  // color of disabled menu items red
  // fgi: 'red',
  disabled: [
    // you can have a list of labels to be disabled
    // at startup here.
  ]
});

var sd = 'Self Distruct',
    esd = 'Enable \'Self Distruct\' (!)';

menu.reset();
menu.write('MARVIN\'S TODO LIST\n');
menu.write('-----------------------------\n');

menu.add('Complain');
menu.add('Whine');
menu.add('Do Nothing');
menu.add(sd);

menu.write('-----------------------------\n');
menu.add(esd);
menu.add('EXIT');

menu.on('select', function (label) {
  if (label === esd) {
    menu.enableMenu(sd);
    menu.disableMenu(esd);
  } else {
    menu.close();
    console.log('Marvin will ' + label.toLowerCase() + ' now!');
  }
});
menu.createStream().pipe(process.stdout);
menu.disableMenu(sd);

#usage

var disabler = require('terminal-menu-disabler')
disabler(menu, opts);

• menu is an instance of a terminal menu created with terminal-menu
• opts is an object, which may have following properties
  • opts.fgi: Foreground color for inactive menu items. This also becomes the background color for inactive menu items when it is selected.
  • opts.disabled: An array of string literals indicating the menu items to be disabled on startup.

After calling disabler(menu, opts), two functions will be injected to menu, which you can use to enable/disable individual menu items.

• menu.enableMenuItem(item)
• menu.disableMenuItem(item)

item can be a label (string) or a zero based index (number) of a menu item.
