Node.js pad

Build Status

Node Pad is a simple and elegant function to pad strings in both left and right directions.

Usage

pad('pad', 5)      // "pad  " 
pad(5, 'pad')      // "  pad" 
pad('pad', 5, '+') // "pad++" 
pad(5, 'pad', '+') // "++pad" 

Options

Options are provided as a third argument and are all optional. A string argument it is interpreted as the "char" option. Accepted options include:

  • char (string)
    The character used to fill the gap.
  • colors (boolean)
    Ajust to hidden terminal color characters, you may also use require 'pad/lib/colors' to avoid passing this option.
  • strip (boolean)
    Remove characters from text if length smaller than text length, default to "false".

Left padding: pad(length, text, [options])

Left padding occurs when the first argument is a number and the second argument is a string.

var pad = require('pad');
pad(5, 'pad', '-').should.eql('-pad');

Right padding: pad(text, length, [options])

Right padding occurs when the first argument is a string and the second argument is a number.

var pad = require('pad');
pad('pad', 6).should.eql('pad   ');
