term-list

Renders an interactive list to the terminal that users can navigate using the arrow keys. Developers can bind to "keypress" events to support removal or opening of items etc.

Installation

$ npm install term-list

Example

A fully interactive list demonstrating removal via backspace, and opening of the websites via the return key.

var List = require('term-list');
var exec = require('child_process').exec;

var list = new List({ marker: '\033[36m› \033[0m', markerLength: 2 });
list.add('http://google.com', 'Google');
list.add('http://yahoo.com', 'Yahoo');
list.add('http://cloudup.com', 'Cloudup');
list.add('http://github.com', 'Github');
list.start();

setTimeout(function(){
  list.add('http://cuteoverload.com', 'Cute Overload');
  list.draw();
}, 2000);

setTimeout(function(){
  list.add('http://uglyoverload.com', 'Ugly Overload');
  list.draw();
}, 4000);

list.on('keypress', function(key, item){
  switch (key.name) {
    case 'return':
      exec('open ' + item);
      list.stop();
      console.log('opening %s', item);
      break;
    case 'backspace':
      list.remove(list.selected);
      break;
  }
});

list.on('empty', function(){
  list.stop();
});
