AW: [plt-scheme] word completion for module based languages

as I already mentioned in the last mail, which unfortunately wasn't sent to
the list, my language is not augmenting the capability-value method. I read
docs, looked in the source, tried different things, the whole day but didn't
come to a solution. Concerning the capability-value example below I must
make a stupid mistake, because whereever I put it in my code I get 

expand: unbound variable in module in:
drscheme:language-configuration/internal:get-all-manual-keywords

Well, I looked up in private/drsig.ss that get-all-manual-keywords is a
method of drscheme:language-configuration/internal since I thought this
might be the mistake because
drscheme:language-configuration:get-all-manual-keywords brought up the
respective mistake. So what I'm doing wrong?

On the other hand I found that 'drscheme:autocomplete-words is #t. Also it
seems to me get-all-manual-keywords is the default for
'drscheme:autocomplete-words is #t. So it should just work without
augmenting capability-value. Is that true? In my language "no completions
available .." is the only thing I see.

'gui-debugger:debug-button is also #t. I defined the method
debugger:supported? in the
drscheme:language:module-based-language->language-mixin of my language. The
button is there and clickable not depending on my debugger:supported?
method. But after clicking the debugger panels don't show up although in the
background something happens. If I want to debug (+ 1 2) after some time the
interaction window opens and displays the result. The debugger:supported?
method seems also to be set to #t by default. But something suppresses the
debugging.

Any help appreciated.
Robert

[ Matthew? Greg? A debugger question below. ]

Is your language augmenting the capability-value method? Perhaps you need
something like this:

      (define/augment (capability-value key)
        (cond
          [(eq? key 'drscheme:autocomplete-words)
           (drscheme:language-configuration:get-all-manual-keywords)]
          [else (drscheme:language:get-capability-default key)]))

You might want to check over the docs for

  drscheme:language:register-capability

to see if there are other capabilities you want to enable.

For the debugger, it looks like you want to both respond with #t to the
'gui-debugger:debug-button capability (add to the above method), and define
the debugger:supported? method, which should also return #t. I'm just
inferring that from the source, tho, so Matthew or Greg may know better.
