Technical Papers
Over the years we have written a number of technical papers on various aspects of Dolphin Smalltalk and its underlying frameworks. These are available via the following links:
Stacks Image 156
The Interpreter Is Dead (Isn't It?) -- Why we chose to go with an interpretive Virtual Machine for Dolphin rather than one based on a JIT compiler. This paper was presented at the OOPSLA 99 Workshop:
“Simplicity, Performance and Portability in Virtual Machine Design”

Twisting the Triad -- An overview of the origins of Dolphin's MVP application framework, with respect to the more traditional Smalltalk MVC framework .

Extending SUnit to Test SASE Events -- A discussion of our extensions to SUnit (the Smalltalk unit testing framework) enabling tests to be written for Self-Addressed Stamped Envelope event based systems (#trigger:#when: etc.).
Stacks Image 159
ANSI Smalltalk/98 (X3J20) Draft -- Dolphin Smalltalk aims to be largely ANSI Smalltalk 98 compliant. The full standard is available for a reasonable charge from ANSI.org but the final draft is also available for free download via the adjacent link.
Here are the download files for current and previous versions of Dolphin Smalltalk together with various other miscellaneous downloadable resources. Click on each section title to expand the contents below it.

Installing Dolphin


Once you have downloaded and installed the software you will need a serial number to unlock the product the first time you run it. If you have not already done so, you can purchase a license for Dolphin Smalltalk X6 Professional from our Online Shop. If you intend to use the Community Edition then you can apply for a free serial number when you first run the software.

When you first install Dolphin you should always run a Live Update from the System Folder to ensure that you have the latest software patches

Tip: Serial Numbers


Your serial number, when you receive it, can contain both O (oh) and 0 (zero) characters. To avoid the possibility of mistyping it is advisable to use copy/paste to transfer it into the Dolphin unlock dialog.
