wide-align

A wide-character aware text alignment function for use in terminals / on the console.

Usage

var align = require('wide-align')

// Note that if you view this on a unicode console, all of the slashes are
// aligned. This is because on a console, all narrow characters are
// an en wide and all wide characters are an em. In browsers, this isn't
// held to and wide characters like "古" can be less than two narrow
// characters even with a fixed width font.

console.log(align.center('abc', 10))     // '   abc    '
console.log(align.center('古古古', 10))  // '  古古古  '
console.log(align.left('abc', 10))       // 'abc       '
console.log(align.left('古古古', 10))    // '古古古    '
console.log(align.right('abc', 10))      // '       abc'
console.log(align.right('古古古', 10))   // '    古古古'

Functions

align.center(str, length) → str

Returns str with spaces added to both sides such that that it is length chars long and centered in the spaces.

align.left(str, length) → str

Returns str with spaces to the right such that it is length chars long.

align.right(str, length) → str

Returns str with spaces to the left such that it is length chars long.

Origins

These functions were originally taken from cliui. Changes include switching to the MUCH faster pad generation function from lodash, making center alignment pad both sides and adding left alignment.
