Overview

A RacketCon talk presenting Fructure, a prototype extensible structured editing engine in Racket. Language providers define syntactic forms and refactorings as rewrite rules, and editing operates on program structure rather than on text.

On Hacker News

Cited as a leading example of structural editing whenever threads discuss alternatives to text-based code editors.

I've seen a few attempts at "structure editors" which are keyboard driven but limit what you can type so it's always syntactically correct. Fructure is an example which looked promising! [VIDEO]

For folks interested in this sort of thing, Andrew Blinn gave a neat talk[1] pertaining to structured editing at Racketcon, which credits Cyrus’ work with Hazel. [1] [VIDEO]

disconcision · 2021-08 · Reference

using a lisp here simplifies things from implementation and interaction model perspectives. you already have a simple, canonical AST out of the box, which in-principle suffices to support the entire language, not just a toy version. so it makes sense lisps are attractive targets for getting something rolling in this space, though it's certainly debatable whether it's long-term the best choice. (my own efforts in this space (a structured editor in racket), which i was able to get going as a novice programmer: [VIDEO] )
