You might want to do a quick "cvs update" because I just updated
some of the "cruft" that had been sitting in the Shell.java class
for some time. Oh wait, I take that back. I checked the "user"
visible CVS at scriptics and last nights changes are not in there
yet (you will have to wait until tommorow).
I do not really think it is a good idea to reimplement the
IO stuff from Jacl in Tcl Blend. Much of the Jacl IO
stuff in the Shell class is just a bunch of ugly
hacks that are needed because the Java IO libs
do not support non blocking IO. If you really want to
make the Shell class work in both Jacl and Tcl Blend, it
might be better to abstract out the bits that do the IO
from the bits that send the event to the interp. The bits
that send to values to the interp is what you want to
show off anyway.
