In a foreign function, how do I unify an 'input' Variable with a list?

[hits-nlp]

I have switched to the refactor branch in the meantime.

Now I want to write a function like this:

def my_function(input_var, output_var):
# compute some list of values based on input_var

'assign' / unify this list with output_var, such that it is accessible from within prolog.

return True

Prolog.register(my_function)

I managed, somehow dirty, to assign a list value to output_var._value, which is probably wrong, and which did not pass the value to output_var such that it was accessible.

Is what I want to do possible?

Thanks,
Christoph

OK, got it myself ;-)
I applied the changes submitted by @tkchouaki in one of the pull requests.
Seems to work now...
