easily create complex multi-column command-line-interfaces.


var ui = require('cliui')()

ui.div('Usage: $0 [command] [options]')

  text: 'Options:',
  padding: [2, 0, 2, 0]

    text: "-f, --file",
    width: 20,
    padding: [0, 4, 0, 4]
    text: "the file to load." +
      chalk.green("(if this description is long it wraps).")
    width: 20
    text: chalk.red("[required]"),
    align: 'right'


Layout DSL

cliui exposes a simple layout DSL:

If you create a single ui.row, passing a string rather than an object:

as an example…

var ui = require('./')({
  width: 60

  'Usage: node ./bin/foo.js\n' +
  '  <regex>\t  provide a regex\n' +
  '  <glob>\t  provide a glob\t [required]'


will output:

Usage: node ./bin/foo.js
  <regex>  provide a regex
  <glob>   provide a glob          [required]


cliui = require('cliui')

cliui({width: integer})

Specify the maximum width of the UI being generated. If no width is provided, cliui will try to get the current window’s width and use it, and if that doesn’t work, width will be set to 80.

cliui({wrap: boolean})

Enable or disable the wrapping of text in a column.

cliui.div(column, column, column)

Create a row with any number of columns, a column can either be a string, or an object with the following options:

cliui.span(column, column, column)

Similar to div, except the next row will be appended without a new line being created.


Resets the UI elements of the current cliui instance, maintaining the values set for width and wrap.
