Re: maximum number of radio targets?

[Carsten Dominik <dominik@science.uva.nl>]

Hi John, I think you are *clearly* overdoing the radiolink feature.   
The problem is that the implementation uses font-lock to activate  
matches, so that these are always up to date.  This clearly means that  
the number of links must be limited.  I am not sure what the  
limitation is in Emacs, but I would also suspect that, with this many  
radio targets, you should be feeling the speed impact with every  
single character you type - oy you must either have a *very* fast  
machine - or be a sloooow typist :-)     ?

With this many links, I guess a different implementation for radio  
links would be needed, one that does not use font-lock, but some  
mechanism that uses idle time.

We don't have such a mechanism yet. There are some plans, in  
particular to support automatic inter-file links like HOWM does it, by  
these have not moved beyond the "wishful thinking" stage.

This could be a nice extension!  Anyone feels challenged to implement  
it?
