Amber Smalltalk, formerly known as Jtalk, is an implementation of the Smalltalk-80 language that runs on the JavaScript runtime of a web browser. It is designed to enable client-side development using the Smalltalk programming language.[1]
Amber includes an integrated development environment with a class browser, workspace, transcript, object inspector and debugger. Amber is written in itself, including the compiler, and compiles into JavaScript, mapping one-to-one with the JavaScript equivalent. Amber was created by Nicolas Petton.[2]
Amber was influenced by an earlier Smalltalk in browser project, called "Clamato", created by Avi Bryant.[2][3] Both Amber and Clamato use Parsing Expression Grammar (PEG) libraries for parsing Smalltalk sourcecode. Amber uses the JavaScript based PEG.js library[4]Cite error: The <ref> tag has too many names (see the help page). written by David Majda and Clamato uses PetitParser, a Smalltalk based library written by Lukas Renggli.[2] Both Clamato and Amber were influenced by earlier work by Dan Ingalls in developing the Lively Kernel implementation of Morphic in the web browser using JavaScript.[2][5]
Started with version 0.12.0, Amber modules are compiled to AMD modules. Starting in version 0.12.6, the development helper CLI tool is extracted to dedicated module 'amber-cli', which can be installed from npm; and setting up the project and its JS ecosystem (bower, npm, grunt) is greatly simplified using this CLI tool by issuing 'amber init' and answering a few questions. This makes Amber Smalltalk easier to use for people coming from Smalltalk world having little JS experience. new text here
