I have completely rewritten From HtDP to Racket based on a new approach that gives, I hope, more opportunity to introduce Racket. The new version is on its own git repo:
This repo contains the documentation, which is more detailed than in previous posts. It is available under the doc/
directory within the repo. The main html doc is htdp2racket.html
.
If you don't want to fork the repo, you can still look at the documentation by downloading the doc directory and opening the html file referred above on your web browser.
