Current Release

Downloads come as *.zip, *.tar.gz, or *.dmg archives. On macOS, you must drag the included *.app file out of your ~/Downloads folder to avoid translocation; mv will not work. On Windows, you must confirm a SmartScreen warning since executables are not yet code-signed.

Current Trunk (Image/Bundles)

You can always take a look at the progress in the latest alpha version (aka. Trunk). Feel free to contribute to the next Squeak release with commits to the inbox. Alpha versions are not expected to be stable. All bundles (i.e., image + sources + vm) whose filename contains a YYYYMMDDhhmm token include the last stable VM. Some Trunk features might benefit from the latest VM (aka. nightly build), which can be downloaded from the OpenSmalltalk-VM repository on GitHub.

Custom Installation

The Squeak/Smalltalk programming system consists of three parts:

• a virtual machine for your platform,
• both image and changes files of a particular version, and
• a sources file for the particular image file.

The image, changes, and sources files should be kept in the same folder. The base name of the image file must match the one of the changes file.

Windows/macOS: You can either drag the image file onto the virtual machine or double click the virtual machine. If there is more than one image file in the folder, a window will appear asking you which one to open.

Linux: Make sure that you have X11 installed, and that the squeak.sh script is executable. For 32-bit Squeak on a 64-bit platform, also have 32-bit libraries installed. Run the script with the image file as a parameter.

Virtual Machines

The virtual machine (VM) executes Squeak image files on a particular platform. There may be more recent versions here than ones included in the all-in-one package.

Image and Changes

The image file contains a snapshot of all living objects in Squeak. The changes file represents a textual log of all source code run and modified—it is like a simple, local versions database.

Sources

The sources file contains all source code of the base system. Just like the changes file, it also includes comments, time stamps, and custom formatting.

The first version of Squeak was released in 1996 at Apple Computer. It is a direct descendant of Smalltalk-80. While Squeak still supports the Model-View-Controller (MVC) model, its preferred UI framework is Morphic, which has been derived from the framework of the same name developed for Self.

Squeak is a self-supporting system that allows to generate new virtual machines (VMs) mostly from Smalltalk code. Originally developed on the Macintosh, members of its user community have since ported it to numerous platforms including Windows, macOS, and Linux.
