API

boxup(input, [options])

input

Type: String

The text inside the box.

options

width

Type: Number, 'Percentage'

Default: auto

The width of the box, include padding and borders.

• width is a percentage string, the width is relative to the terminal's width.
• width is a number, it's a absolute width.

• any other invalid values will be treat as auto.

  Note: if the width is greater than tha terminal's max width, then we will take terminal's max width as the box's width.

textAlign

Type: String

Default: left

Values:

• left
• center
• right

Text alignment in the box.

boxAlign

Type: String

Default: left

Values:

• left
• center
• right

The alignment of the box.

borderStyle

Type: String

Default: single

Predefined values:

• single

  ┌───┐
  │foo│
  └───┘

• double

  ╔═══╗
  ║foo║
  ╚═══╝

• round (single sides with round corners)

  ╭───╮
  │foo│
  ╰───╯

• single-double (single on top and bottom, double on right and left)

  ╓───╖
  ║foo║
  ╙───╜

• double-single (double on top and bottom, single on right and left)

  ╒═══╕
  │foo│
  ╘═══╛

• classic

  +---+
  |foo|
  +---+

borderChars

Type: Object

Default: null

Specify the ANSII char used to build the box, can have the following keys:

{
    topLeft    : '+',
    topRight   : '+',
    bottomLeft : '+',
    bottomRight: '+',
    top       : '-',
    bottom    : '-',
    horizontal: '-',
    left    : '|',
    right   : '|',
    vertical: '|'
}

Which horizontal defined both top and bottom chars, as the same vertical defined both left and right chars.

If we have already specified a border style, such as single, we can use this option to midify some char:

var options = {
    borderStyle: 'single',
    borderChars: {
        topLeft    : '1',
        topRight   : '2',
        bottomLeft : '3',
        bottomRight: '4'
    }
};

If the borderStyle is empty or not a valid value, we should define necessary chars to build the box, that's to say, all the corners and all the borders should be specified:

var options = {
    borderStyle: '', // empty
    borderChars: {
        // corners are necessary
        topLeft    : '1',
        topRight   : '2',
        bottomLeft : '3',
        bottomRight: '4',

        // borders
        top   : '-',  // or horizontal: '-'
        bottom: '-',  // or horizontal: '-'
        right : '|',  // or vertical: '|'
        left  : '|'   // or vertical: '|'

    }
};

• black
• red
• green
• yellow

    margin: {
        top   : 1,
        right : 2,
