Hi,
Would it be possible to add the capability for functions to register how
they would like to complete themselves.
Currently, there is the .addFunctionInfo, but it allows only functions to
register a static list of potential completions, I was thinking of a way to
register not a fixed list of possible completions, but a __function__ that
would calculate completions dynamically.
This could be useful for the "new" function in R, if associated with
something that can retrieve the current list of S4 classes (not sure this
exists).
Another example of where this could be used would be the .jnew function
from rJava, where the first argument is a java class, associated with
something that can complete java class names.
That should be useful (library, data, etc. are already hard-coded to
do special completion, but there is no reason for them to be special).
I'll have to think about how best to implement this.
I should have time to work in this in a couple of weeks (I also hope
to tackle your earlier request on $ completion then).

Great.
I guess there are a few challenges, currently library, etc ... only use
the special completion feature for their first argument.
it might make sense to expand on this, for example the data argument of
a lattice call might be interested in the list of available data frames ...
Let me know if I can be of help when you tackle this.
