justify

Left or right (or both) justify text using a custom width and character

Usage

var justify = require('justify');

justify('foo', 'bar', 10);
// => "foo    bar"

justify('foo', 'bar', 15);
// => "foo         bar"

You can pass a custom character or string to use a spacer as well, justify will cycle through all characters in c until a string of the right size is created

justify('foo', 'bar', 15, {c: '.'});
// => "foo.........bar"

justify('foo', 'bar', 15, {c: '-='});
// => "foo-=-=-=-=-bar"

You can also omit the first or second argument (or both) to left or right justify a string only

justify('foo', null, 10);
// => "foo       "

justify(null, 'bar', 10);
// => "       bar"

justify(null, null, 10);
// => "          "

justify(null, null, 20, {c: '#'});
// => "####################"

This module also gracefully handles size constraint violations

justify('foo', 'bar', 7);
// => "foo bar"

justify('foo', 'bar', 6);
// => "foobar"

justify('foo', 'bar', 5);
// => "foobar"

justify('foo', 'bar', 5, {throw: true});
// => [Error: justify: strings cannot fit into width 2]
