Adding Interactive Visual Syntax to Textual Code:

This paper proposes a mechanism for conveniently extending textual programming languages with problem-specific visual syntax. It argues the necessity of this language feature, demonstrates the feasibility with a robust prototype, and sketches a design plan for adapting the idea to other languages.

In an odd coincidence, I just linked a different project from 2/3 the same authors ten minutes ago 😊 https://futureofcoding.slack.com/archives/C5T9GPWFL/p1600422945001300?thread_ts=1600195910.451200&cid=C5T9GPWFL

Is a pre-print or something available to read?

I searched and couldn't find it anywhere

No worries. Lets wait for October.

Leif Andersen sent me a pre-print. I like the approach of the paper, which is to expand Racket's macro system to include

define-interactive-syntax

that operates at edit time. (In addition to the compile time and run time execution stages.)
