Sandblocks: A Projectional Block-Based Editor for Squeak

25 October, 2024

[sandblocks]

Sandblocks is a projectional, block-based programming environment
written in Squeak/Smalltalk.

Projectional editors are promising for tasks like language
composition and domain-specific projections. Effective user
interaction requires clear communication of program structure and
supported editing operations. While making the abstract syntax tree
visible can enhance clarity, it often leads to increased space usage
and potential usability issues. Sandblocks is an early prototype of a
tree-oriented projectional editor for Squeak/Smalltalk, which aims to
minimize space while clearly visualizing the tree structure.

For more information on projectional editing, you can start by
reading Martin Fowler's explanation (here), in which he describes it
as an alternative to source editing.

Give it a Try!

You can find the simple installation instructions on the project page
here. The page specifically mentions Squeak 5.3, but it seems to work
similarly well with Squeak 6.0. Sandblocks is a research prototype,
so be sure to save often while working with it.

Have a great time with Smalltalk and keep on Squeaking!
