Sjacket stated goal is to become a common backend for Clojure editors.
- cheap, always up-to-date, parse trees and views
- structural transformations by simple sexpr transformations (you don't have to care about the source layout and comments, sjacket does its best to preserve them)
Sjacket is still in its infancy: despite having thought about it for a while https://twitter.com/cgrand/status/165471721531506689, I only wrote some code in a TDD (Talk Driven Development) fashion for EuroClojure 2012 (see Not So Homiconic.pdf for the slides).
The short term goal is to provide a demo ui which will serve as an example for integrators. Once the demo ui is done, work on the transformations will resume.
