Experiments in Dynamic Software, Visualisations, Creating a JVM Language, UI, and More

For detail about what this repository is about, see this article.

This is a soup of unpolished code from my explorations of Clojure's (and the JVM's) potential to create dynamic and humane computing experiences.

The projects in this repository are viewed in a graphical application, powered by Skija and JWM.

Usage: clojure -M:dev or bb dev

Important note: repository has been configured specifically for my personal computer (running Windows), so you may need to make some modifications to get some of the code working. Also, certain locally-installed fonts are assumed to be present.

Contents:

• Dependency graph viewer
• JVM language ("Squawk") that acts as a dynamic version of Java, as a Lisp dialect.
  • Text editor and navigator implemented in Squawk
• Error boundaries that show an image of the canvas before the error
• Stacktrace viewer where you can expand the frames to see the source of the relevant var and the line of the call site
  • Collapses repeating frames of a StackOverflowError
• Basic text input (broken)
• Basic vim-like editor -- to be done better
• Clojure var browser (editor is broken)
• Basic file browser with delete function
• Partially implemented structural Clojure editor (a bit broken on high-DPI displays)
• Glamorous Toolkit -like inspector (digger) -- use tap>
• Quantum circuit simulation
• Some partially implemented stuff for catching errors (see statusbar) and suspending/restarting threads via Java Debug Interface
• Visual display monitor brightness control (requires macOS and ddcctl command-line tool)
• Experiments developing new UI toolkits
• Text box with most features that you would expect
• Experiment with a more interesting file tree viewer
