[plt-scheme] word completion for module based languages

Thanks. I'm still hoping one of the debugger guys knows what is going
on there, but for autocompletions, you need this method:

      (define (make-mytest-plt-elk-language base)
        (class (drscheme:language:module-based-language->language-mixin

(drscheme:language:simple-module-based-language->module-based-language-mixin
                 base))
          (inherit get-language-position)
          (define/override (get-language-name)
            language-name-plt-elk)
          (define/augment (capability-value key)
            (cond
              [(eq? key 'drscheme:autocomplete-words)
               (get-all-manual-keywords)]
              [else (drscheme:language:get-capability-default key)]))
          (define (debugger:supported?) #t)
          (super-instantiate ())))

with this helper function defined yourself. I didn't export
get-all-manual-keywords since it was so short and I wasn't sure that I
would be able to support that interface indefinitely. But in any case,
it is easy to write it yourself with the current world.

      (define get-all-manual-keywords
        (let ([words #f])
          (λ ()
            (unless words
              (set! words (text:get-completions/manuals #f)))
            words)))


hth,
Robby
