Abstract
--------

This is a JavaScript implementation of POSIX sprintf(3)-style string formatting
for use in [Node.js](http://nodejs.org/) based server and browser based client
environments.

Getting sprintf.js
------------------

You can conveniently get sprintf.js in various ways:

- Git: directly clone the official repository

  `$ git clone https://github.com/rse/sprintfjs.git`

- NPM: install as client component via the NPM package manager:

  `$ npm install sprintfjs`

- cURL: downloading only the main file from the repository

  `$ curl -O https://raw.github.com/rse/sprintfjs/master/sprintf.js`

API
---

The API is similar to POSIX [sprintf(3)](http://www.unix.com/man-page/posix/3/fprintf/).
It is exposed via AMD and CommonJS under the module name `sprintf`
and on the global `window` object in browser environments. The single
exposed API method is (in TypeScript definition notation):

    sprintf(fmt: String, ...arg: any[]): String;

It supports all standard POSIX [sprintf(3)](http://www.unix.com/man-page/posix/3/fprintf/)
features like `sprintf("%.2f", 12.3456)` &rarr; `12.35` and `sprintf("(%-6s)", "foo")` &rarr; `(foo   )` plus
(in addition to the usual positional arguments) two special argument referencing features:

- Indexed Arguments:<br/>
  `sprintf("%2$s baz %3$s baz %1$s", "foo", "bar", "quux")` &rarr; `bar baz quux baz foo`

- Named Arguments:<br/>
  `sprintf("%(bar)s baz %(quux)s baz %(foo)s", { foo: "foo", bar: "bar", quux: "quux" })` &rarr; `bar baz quux baz foo`
