Package Exports

pad
pad/lib/colors

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pad) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Node.js pad

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

Usage

The API is quite simple:

const pad = require('pad')
pad('pad', 5)      // "pad  "
pad(5, 'pad')      // "  pad"
pad('pad', 5, '+') // "pad++"
pad(5, 'pad', '+') // "++pad"

For TypeScript users, the type definition file is located in "./lib/index.d.ts" and declared inside the "package.json" file.

This package is written for ES6 supported by Node.js version 7.5 and above. For older browsers or older versions of Node.js, use the modules inside "./lib/es5".

const pad = require('pad/lib/es5')
pad('pad', 5)      // "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".
fixed_width (boolean)
An optimization option to disable the usage of the wcwdith package to handle the discovery of characters using more than one column for display. one column to display
wcwidth_options (object)
Options passed to the wcwidth package used to calculate the display width of characters using more than one column.

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   ');
