Show Interactions a la Dr. Racket

[devn]

I assume the following would be quite a bit of work, but Dr. Racket has an absolutely beautiful system where you can "show interactions", which means that when your mouse hovers over a variable or function, an arrow or arrow(s) are rendered on the screen that show how that thing came to be. For example:

(ns foo.core)

(def hello "hello")

(defn hello-someone [someone]
  (str hello ", " someone))

When hovering over someone, an arrow is drawn from [someone] to someone.
When hovering over hello, an arrow is drawn from (def hello ...) to (str hello ...).

I know this is probably pie in the sky, but every time I see this in Dr. Racket I am flabbergasted at how nice that is.

The editor-known-as Dr Scheme was my general purpose lisp editor, and this a request that i was thinking about raising. So I think it was very handy as well.

It's basically a scoped search with highlighting (that was easily said).

@arthuredelstein can we draw arrows over the code window ATM with clooj?

This is an awesome feature.

@frenchy64 @arthuredelstein Is this worth looking into or am I making trouble?

Hi Devin,

Sorry, I should have responded earlier. I'm not familiar with this
feature -- can you point me to a screenshot or other details to help
me decide?

Thanks,
Arthur

Hi Devin,

I like the functionality (showing all locations of a name) but I'm not
sure I would do it with arrows. What about highlighting every
occurrence of a given name? Netbeans has a similar functionality (see
http://oi39.tinypic.com/23t4a6u.jpg
Here the variable "softTable_" has been selected on line
165, and as a result of this selection, every other occurrence is
automatically highlighted).
