Dolphin Smalltalk, or "Dolphin" for short, is an implementation of the programming language Smalltalk for Microsoft Windows.

The Dolphin 7 version release coincided with the project becoming free and open-source software under an MIT License.1

Dolphin uses an integrated development environment. The toolset of this Smalltalk dialect include an integrated refactoring browser, a package browser and a WYSIWYG "view composer". Dolphin deviates from the conventional Smalltalk framework of model–view–controller (MVC), instead using model–view–presenter (MVP).

Features

  • Integration of the Refactoring Browser tools from Refactory Inc.
  • Package-based browsing environment as an alternative to a conventional Smalltalk class hierarchy browser.
  • A tabbed container to manage Dolphin browsers and tools and associating them together with a given idea or workflow. The goal is to save screen space and clutter and to help developers focus on their train of thought.
  • Source code management very similar to the ENVY source code manager that was available for some other commercial Smalltalk dialects.
