Amber is an implementation of the Smalltalk language that runs on top of the JavaScript runtime. It is designed to make client-side development faster and easier.

Overview
--------

Amber is written in itself, including the parser and compiler. Amber compiles into efficient JavaScript, mapping one-to-one with the equivalent JavaScript. There is no interpretation at runtime.

Some highlights:

-    Amber features an IDE with a Class browser, Workspace, Transcript, a ReferencesBrowser supporting senders/implementors and class references, basic Inspector and even a beginning of a Debugger and a unit TestRunner.
-    [Pharo Smalltalk](http://www.pharo-project.org) is considered as the reference implementation.
-    Amber includes a canvas to generate HTML, like [Seaside](http://www.seaside.st)
-    Amber can use Javascript libraries and the current IDE is built on [jQuery](http://www.jquery.com)
-    You can inline Javascript code and there are many ways to interact between Amber and Javascript


Getting Amber
-------------

Amber is shipped as a cli tool to create new projects and assist with development tasks in a [npm](http://npmjs.org) package  `amber-cli`
and as a library to be used by projects in a [bower](https://github.com/bower/bower) package `amber`.

Do this [1] to create an Amber project of your own and start working in it:

    # Install the CLI tool `amber-cli` and supporting tools
    npm install -g amber-cli bower grunt-cli

    # Initialize your project (directory must be empty)
    cd /path/to/myproject
    amber init

    # (optional) Install backward compatibility
    bower install amber-compat-es5 --save   # be loadable in older browsers
    bower install amber-compat-ie8 --save   # additional tweaks to load in IE8

    # Serve amber on localhost:4000
    amber serve

The [Getting started](https://github.com/amber-smalltalk/amber/wiki/Getting-started) page shows more details on ways to obtain Amber and start a project.

[1] For installation to work, you need to install `node`, `npm` and `git` (in Windows, use Git for Windows and select "Run Git from Windows Command Prompt" and "Checkout Windows-style, commit Unix-style" installation options).
