A wide-character aware text alignment function for use in terminals / on the
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'
align.center(str, length) →
with spaces added to both sides such that that it is length
chars long and centered in the spaces.
align.left(str, length) →
with spaces to the right such that it is length
align.right(str, length) →
with spaces to the left such that it is length
These functions were originally taken from
. Changes include switching to the
MUCH faster pad generation function from
, making center alignment pad
both sides and adding left alignment.
