Company backend about racket-mode

[greghendershott]

Although I don't use completion myself -- otherwise it would probably already be in racket-mode :) -- this sounds like a good idea.

In Racket I believe namespace-mapped-symbols would be the way to get the list of what is currently required. Which seems simple enough.

But not sure the best way to marshal that from Racket to Elisp.

It's not a tiny list, even in racket/base:

#lang racket
(length (namespace-mapped-symbols)) ; => 1837

2296 symbols in full #lang racket.

And serialized to a string:

(string-length (string-join (map symbol->string (namespace-mapped-symbols))
                            ","))
; => 30822

So I'd want to think about how to marshal from Racket to Elisp, cache it, and how to invalidate/refresh the cache.

Just an update that I started working on this recently. It's still in rough shape so nothing to push quite yet.

This is done as of commit af52ee8 and commit 72da219.

You should be able to get this via MELPA by updating racket-mode.

Please let me know how it works for you?
