Glisp, an acronym for Graphical LISP, is the prototyping project to experiment what if a design tool meets a way of creative coding, and obtain the self-bootstrapping power of LISP. This tool looks like the integration of Illustrator and Processing IDE at a glance. And in fact, it adopts both benefits of intuitiveness of direct manipulation on GUI and abstractness of programming language.

Glisp literally uses a customized dialect of Lisp as a project file. As the Code as Data concept of Lisp, the project file itself is the program to generate an output at the same time as a tree structure representing SVG-like list of shapes. And even the large part of the app's built-in features are implemented by the identical syntax to project files. By this nature so-called homoiconicity, artists can dramatically hack the app and transform it into any tool which can be specialized in various realms of graphics -- daily graphic design, illustration, generative art, drawing flow-chart, or whatever they want. I call such a design concept "purpose-agnostic". Compared to the most of existing design tools that are strictly optimized for a concrete genre of graphics such as printing or UI of smartphone apps, I believe the attitude that developers intentionally keep being agnostic on how a tool should be used by designers makes it further powerful.

Features list I've been fantasizing

✨: High priority
🍡: Personally think it'd be cool
🌶️: Important but I have no clue how to do

• UI enhancements
  • ✨Selects path/group by clicking viewport
  • ✨Transplants Programmable Pen Tool
  • Touch-screen support
  • Much more intuitive interface for designers I prototyped here
• Improve the GUI to allow non-programmers edit the project without seeing any Lisp code
  • ✨Layer list view
• Lisp interpreter optimization/enhancement
  • 🌶️ Incremental evaluation system to avoid the overhead by re-calculating entire project for each tweak
  • Incremental Lisp parser
  • 🌶️ Enables to refer other node's value by relative path without explicitly defining a symbol, like Houdini's ch("../transform/tx") expression
  • Headless REPL environment to render images by command (partially supported)
  • Standalone JS library to dynamically render the sketch embedded in a web page
• Timeline features
  • Video exporter
  • AE-like layer view and curve editor
  • 🍡 Velocity/acceleration based easing editor
• Raster image manipulation
  • Writes custom filters in GLSL (Interactive Shader Format might be useful)
  • 🍡 Captures still image from video input (e.g. webcam) to make a stop-motion
• Abstraction of user inputs
  • Not only mice and keyboards, add support to bind commands with any controller's inputs via OSC/MIDI on the fly while you design. The notion "remembering hotkeys" will be vanished.
  • 🍡 Wouldn't it be cool if we can even use Leap Motion to record an animation...?
  • Input hooks. Quantizing, copying, flipping, and smoothing the mouse coordinate for instances.

Helpful Repositories

• The implementation of Lisp interpreter is the modified version of Make a Lisp project.
• Boolean Operator and some bezier manipulations by Paper.js.
• Bezier curve analyzation by Bezier.js
