[racket] DivaScheme plt broken, due to changes in GUI in v.6(?)

[Wade McReynolds]

Hi, I'm trying again after some time to use the Divascheme editing package
and it's broken in Racket 6.x. I've been told it's probably due to changes
in the GUI, but I'm lost as to interpreting the errors. Any ideas as to the
source of the problem?

The newest version of DivaScheme I can find is:

https://github.com/dyoo/divascheme

It was last updated 7 years ago - and was written for Racket 4.x.

Since then a lot has happened, so you most likely need to fix
several things.

I should have added the error message I'm running into, in case anybody
recognizes something. (I'm a rank novice myself.)

BTW, until someone ports DivaScheme to Racket 6.x...
I think DivaScheme was inspired by Taylor Campbell's `paredit.el` for Emacs:
http://emacswiki.org/emacs/ParEdit
If you want to try out the general approach to sexp-oriented editing, or
just see a video demonstration, you might want to look at `paredit.el`
for now.
