[![Build Status](https://secure.travis-ci.org/adaltas/node-printf.png)](http://travis-ci.org/adaltas/node-printf)

A complete implementation of the **`printf` C functions family**

for [Node.JS][node], written in pure JavaScript.

**Bonus!** You get extra features, like the `%O` converter (which `inspect`s

the argument). See [Extra Features](#extra-features) below.

[![NPM](https://nodei.co/npm/printf.png?stars&downloads)](https://nodei.co/npm/printf/) [![NPM](https://nodei.co/npm-dl/printf.png)](https://nodei.co/npm/printf/)

Use it like you would in C (`printf`/`sprintf`):

It can also output the result for you, as `fprintf`:

assert.eql('  -42', printf('% 5d', -42));

assert.eql('42.90', printf('%.2f', 42.8952));

assert.eql('042.90', printf('%06.2f', 42.8952));

assert.eql('+hello+', printf('+%s+', 'hello'));

The `%O` converter will call [`util.inspect(...)`][util_inspect] at the argument:

assert.eql("Debug: { hello: 'Node', repeat: false }",

  printf('Debug: %O', {hello: 'Node', "repeat": false})

  printf('%2$s: %1$O', {"hello": 'Node'}, 'Test')

assert.eql("With colors: { bar: \u001b[33mtrue\u001b[39m, baz: \u001b[33mfalse\u001b[39m }",

  printf('With colors: %O', {bar: true, baz: false})

  printf('With colors: %+O', {bar: true, baz: false})

you can use **hashes** and **property names**!

  printf('%(temperature)s %(crevace)ss', {

Lenght and precision can now be variable:

assert.eql(' foo', printf('%*s', 'foo', 4));

assert.eql('      3.14', printf('%*.*f', 3.14159265, 10, 2));

assert.eql('000003.142', printf('%0*.*f', 3.14159265, 10, 3));

assert.eql('3.1416    ', printf('%-*.*f', 3.14159265, 10, 4));

Tests are written in [CoffeeScript][coffee] executed with [Mocha][mocha]. To use it, simple run `npm install`, it will install

Mocha and its dependencies in your project's `node_modules` directory followed by `npm test`.

The test suite is run online with [Travis][travis] against the versions 6, 7, 8 and 9 of
