Amber [![Travis CI Status](https://secure.travis-ci.org/amber-smalltalk/amber.png)](https://travis-ci.org/#!/amber-smalltalk/amber)
=====

By Nicolas Petton <petton.nicolas@gmail.com> and [Amber contributors](https://github.com/NicolasPetton/amber/contributors)

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

Building Amber
--------------

Amber uses [Grunt.js](http://gruntjs.com/) as build system since version `0.10.0`.

If you already have Grunt.js v0.3.x installed locally run the following (otherwise ignore these lines):

    cd ${Amber_DIR}
    npm uninstall grunt

To install Grunt.js v0.4.x on the commandline execute the following commands:

    npm install -g grunt-cli grunt-init

Amber depends on some web libraries to work in browser, using bower to manage these dependencies.
To install bower, run:

    npm install -g bower

To get all dependencies, run:

    cd ${Amber_DIR}
    bower install   # dependencies for the web
    npm install     # dependencies for the cli development

And finally, compile Amber using the following command:

    cd ${Amber_DIR}
    grunt

For Windows support check the [Grunt.js on Windows](http://gruntjs.com/frequently-asked-questions#does-grunt-work-on-windows) page.
