Description

This is by far the most extensive Moose release to date. Just take a look at these two trailers:

The key highlights are:

  • It is based on Pharo 3.0.
  • Roassal2 is a complete reimplementation of the core visual engine of Moose.
  • Roassal2 replaced Roassal, EyeSee and Graph-ET, and it features many new things including smooth animations, new composeable builders and several new layouts.
  • All built-in Moose visualizations use Roassal2.
  • Glamour has been extended with a Pager browser and with Rubric as the main text editor.
  • GTSpotter is a new tool that makes it possible to find objects fast.
  • GTInspector saw major usability improvements based on the Pager browser, and it now comes with many object specific extensions.
  • GTPlayground provides a new way to handle scripts and when combined with GTInspector, it can replace the dedicated easels and editors.
  • Moose Finder has been extended with the ability of handling in place visualizations.
  • GTDebugger has been strengthen and was made more robust.
  • PetitParser has been extended with the notion of context which enables elegant island parsing.

New Smalltalk book: Programming Smalltalk

A new book about Smalltalk will be released March 2015:

Programming Smalltalk - Object-Orientation from the Beginning: An introduction to the principles of programming by Johannes Brauer

on Amazon

" A straightforward, step-by-step introduction to clear and elegant object-oriented programming. Using a language that's perfect for this kind of programming, the book has been tested in numerous courses and workshops over ten years.

Programming Smalltalk is particularly suited for readers with no prior programming knowledge. Starting from the first principles of programming, it teaches you how to use and create algorithms (reusable rules for problem-solving) and the basic building blocks of software. It goes on to explain how to develop complete applications and has a whole chapter on web applications as well as case studies.

Now translated into English, this edition was completely revised to be consistent with the latest version of Cincom® VisualWorks®, a professional Smalltalk environment. All examples were created using VisualWorks, which is available without cost for educational purposes, and can be downloaded and installed on any up-to-date computer. "
