By 'ranked output' I meant the following:
If I type, for instance, 'beef' and call the autocompete function. It  
will list:
beef
beef's
beefcake
beefcake's
....

Then I choose 'beefsteak'. After writing further stuff I type 'beef'  
again and call autocomplete. Now it will list:
beefsteak
beef
beef's
beefcake
...

'beefsteak' will listed at the top because NSSpellChecker remembers  
my last choice. And this is done via an unique inSpellDocumentWithTag.

If I write in 'a.m':

int utag = [NSSpellChecker uniqueSpellDocumentTag]

it causes an error because the program is started outside of a cocoa  
application; and there is no SpellDocument referring to.
Furthermore if the a.out is executed the NSSpellChecker is also  
closed, so there is no way to memorise my choices. (?)

I have no idea to pass the tag and language info from TM to a.out!

The same for language: If I type language:nil NSSpellChecker takes  
the language which is set in the document. But there is no document  
for a.out.

Well, I don't know. If I leave it out the program doesn't run.

I tried it out with language "de". I wrote 'Vermö' but nothing  
returns because the Ruby line:

word = Word.current_word(/\w./)

interprets the 'ö' as word boundary. If I type 'Vermög' it lists all  
words beginning with 'g'.

If I use TM directly and type

/PATH/TO/a.out "Vermö" "de"

it works perfectly.

To solve this problem you have to write within the Ruby script  
instead of

word = Word.current_word(/\w./)

word = `cat`

and set the input behaviour of the command to 'Selection' or 'Word'

I don't know but it seems to me that the easiest way to use this  
functionality is to wait for Allan. I guess to implement this in TM  
directly is the cleanest way (?)

Cheers,
