GUIs for the command line.

Why

Command line programs can be hard to learn / use / build.

How

cui is a preinstantiated object that can be require()'d by multiple files and maintain its state. Use cui.push() or cui.splice() to add views or actions (see the Usage section) to a sequence of frames. Users of your program only need to know the name of your program - cui can walk them through providing the rest of the arguments on its own. If a user does know the full command, they can still type it out of course, for example running the basic example any of the following ways is valid:

  • example/basic
  • example/basic Three
  • example/basic Three hi!

Install

npm install cui

Examples

The examples are all executable scripts - try cd'ing into the example folder and typing ./all

Usage

This code below is essentially the same as in example/basic:

var cui = require('cui')
 
cui.push({
  title: 'This is a very basic example.',
  type: 'buttons',
  data: [
    'One',
    'Two',
    'Three'
  ]
})
 
cui.push(function(cb) {
    if (cui.last(1) === 'Three') {
      cui.splice({
        title: 'Three is a special choice!',
        type: 'fields',
        data: 'Please type a word and press ENTER: '
      })
    }
    cb()
})
 
cui.push(function(cb) {
  console.log('You could do something now with: "' + cui.results.join('" and "') + '"')
    cb()
})

Properties

  • args any arguments passed
  • results an array of results collected by views or manually augmented by actions
  • cache a cache object that will be automatically loaded & saved if not null (as a json file named '.cui')

Methods

  • push() add a view or function to the end of the sequence
  • splice() add a view or function after the current frame
  • last(n) return cui.results[results.length - n]
  • print() basically console.log() but with the same indentation level as specified in lib/ui
  • save() persist the cache now - useful if your script may encounter future errors and exit early
