Amber

By Nicolas Petton petton.nicolas@gmail.com and 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 is considered as the reference implementation.
Amber includes a canvas to generate HTML, like Seaside
Amber can use Javascript libraries and the current IDE is built on jQuery
You can inline Javascript code and there are many ways to interact between Amber and Javascript

Building Amber

Since 0.10.0 Amber uses Grunt.js as build system. To compile Amber on the commandline execute the following commands:

cd ${Amber_DIR}

npm install

./node_modules/grunt/bin/grunt
